Hello friends, suppose you are working on your computer and then you realize that your computer is too slow for you. For every computer user the slow computer is one of the most frustrating things in his/her work. You are working on your computer and then you see that your system is taking more than five seconds to open File Explorer or any other file. None of the Windows actually slow down with time, the slowness of your system depends on other factors — May be some kind of virus or high storage usage etc.

If your computer is slowing down and you want to make speed-up your PC then we are here. Today we will tell you some best tips / ways to make your Windows faster. You don’t need to buy any new laptop or PC.

Uninstall Your All Unused Applications / Programs

Whenever you buy a new PC, there are many applications or programs installed, which you don’t even use. So before heading towards next step please uninstall those unused programs. Some programs run in your background and you don’t know that they are running and consuming your storage and making your computer slow as well.

You can simply uninstall these programs from Control Panel as shown in this figure:

Your Unnecessary Startups

There is a Note before going through this step: This Step can affect your PC’s Startup. So use it well.

You can also disable your unnecessary startups in your PC. To do this:

• Go to Task Manager (you can open your Task Manager by Ctrl + Shift + Esc)

• Select Startup

• Disable those you don’t want

Done…

Delete Temporary Files

Temporary files also make your computer slow. To delete the Temporary files in your system you can simply open Run (WINKEY + R) and type temp and press enter. OR Go to This PC and open C Drive and then go to Windows and Temp. View files details and Delete those files which are older than the current dates.

Temp Files' Location

 

Disk Cleanup Your Drives

Clean up your disk by Disk Cleanup. It will not clean up your whole data but only clean the unwanted files. To clean the disk:

In This PC

• Right Click on the Drive / Disk you want to clean up
• Choose on Properties from the dialog box
• Select General and click on Disk Cleanup

Disable the Visual Effects, Shadows and Animation Effects

Windows offer you some beautiful shadows, animation etc. This makes your Windows appearance more beautiful. These effects hardly affect the performance of computer but may slow down it so we will recommend you to disable those shadows, visual effects etc. to disable it:

• Type sysdm.cpl in search box
• Click on Advance Tab
• Select Settings
• And disable some.

If you want to check each effect then you can but we will recommend you to choose ‘Adjust for best performance’ at the top and then click on OK.

Reboot Once / Again

Sometimes many computers start slowing down because they are not rebooted for long time so make sure to reboot your computer.

Scan for Malwares and Viruses

Malwares and Viruses are the common problems which are making your computer slow so please scan your computer fully for checking any malwares or viruses.

Update Your Antivirus

Sometimes your antivirus is out-dated so it will be unable to find different kind of virus. So please use updated antivirus and then scan your computer.

 
Update Your Windows

If your version of Windows is outdated then may it will affect your speed. So check the newer version of your windows.

Check Your Updates

Clean Your PC

Sometimes dust also creates the problem in working of PC. Try to open your PC and clean every part especially fans. You can find many tutorials on internet on How to clean your PC or Laptop etc.

Clean Everything and Start Again

If none of the steps are working then clean everything from your computer after taking your important data and then start your PC as new as it came.

Required More RAM

Random Access Memory also known as RAM. All applications runs on RAM so if the capacity of RAM is less than the required capacity of RAM for specific software then definitely it will slow down your computer. So if you have less RAM then increases it.

Hard Drive Storage

If your Hard Drive is storing very much of data (more than 85% of full capacity), then it will definitely affect your computer speed. So increase your Hard Drive or expand it.

Hardware Problems

Still have some problems, if you tried every single step given above then there are some problems in your Hardware and you have to change some of them.

Still Slow...

If your computer is still slow then it is the time to buy a new one…

I hope this article helps you. If you have any question related to this topic then feel free to comment below and if you have any other step then tell us we will add in this.

Hello friends, today we are going to talk about Encryption and Decryption…

Encryption

Encryption is actually a process of converting a data into such a manner that no one can read or access it except the authorized ones. In the process of encryption, the message or information gets encoded. That encoded information will not be access by anyone. The message or information which is encrypted is known as PlainText. A Cipher is the encrypted algorithm which is used in the process of encryption, means the PlainText (information) is encrypted by Cipher. After then, the PlainText converted into the CipherText, it can only be read by others when it will Decrypted.

In simple language, unencrypted data is known as PlainText, the process is known as Cipher and the result of the Cipher process is known as CipherText, which is actually an encrypted data. Cipher and Code is almost the same things, in both cases the message is encrypted. The encrypted data can only be read by using the key which made it readable for other users.

 Encryption process is not new it was used in ancient time also. For example, Romans and Greeks also sent some secret messages in some unreadable codes. Just like nowadays, the message or information is converted into some unreadable form.

Simple Example for Better Understanding

To understand how this encryption process works, let’s take a simple example:

Firstly we will give every alphabet a unique sign. For example, if you want to write ‘A’ then you will write it ‘Z’, and if you want to write ‘Z’ then you will write ‘A’. To understand it better see the below table.

Here is a list of commonly used words with their code:

SIMPLE:  ABCDEFGHIJKLMNOPQRSTUVWXYZ

CODE:     ZYXWVUTSRQPONMLKJIHGFEDCBA

So according to the above table, if you want to write ‘NEXTISEASY’ then you will write ‘MVCGRHVZB’. This is how the encryption process works. The word NEXTISEASY can be read by anyone but no one can read that CODE which we have written in the place of NEXTISEASY.

Key

Key is very important in order to encrypt the data.  Key is used to unencrypt or encrypt the data known as Shared Key. A Shared Key is distributed to one or two people and those people can use their specific key to read the encrypted data or to encrypt the data. This means that the PlainText can be converted into CipherText or CipherText can be converted into PlainText by using Key.

Decryption

Decryption is the process of changing that unreadable format of data, known as CipherText, into the readable form of data, known as PlainText.  In Decryption, the computer transforms the data which was encrypted. Decryption can be done by using the Key.

Why Encryption?

The main purpose of the Encryption is to secure the confidential data by the attackers. Many organizations have very sensitive data to store so they encrypt that data to prevent their data from the hackers or to be used by others for some illegal works. Many governments use encryption process. Mostly payment card industries use this encryption process to protect their customers’ data because they (their customers) use their cards for payment in many sites so there are many chances that their ID will be hacked or steal, to prevent the spreading or hacking or stealing of their customers’ data they use encryption.

By 1970s, the encryption was only used by some governments to keep their files and information secure but in this modern era, some products or industries are now totally depend on this encryption. Some devices like set—top boxes, modems etc. use encryption process to provide best function. Even your smartphones and SIMs somehow use encryption process to give you best results with security. Every time you use the ATM you are using the process so-called encryption.

As we know that the Cyber Attacks are increasing every single day. So the need of Encryption is also increasing. Encryption can be used in any type whether it is your images on system or your emails in your account or your files or your any specific data etc. May be encryption is not 100% secure but it decrease the chances of attacks.

If you have any question or suggestion then please free to comment below... and Thanks for Reading...

Hello Friends, today we are going to talk about Troubleshooting...

Troubleshooting

Troubleshooting is problem solving applied whenever there is a failed process. It is used to repair that failed process on a system or a machine. It search logically and systemically whole process and find out the problem in process and then solve it. 

This solving process of troubleshooting helps the machine to do operational process again. It needed to find or identified the symptoms in process. When troubleshooting process end, it will requires your confirmation to repair it. If you give it the confirmation then it will repair it to its working state.

In general words, troubleshooting identified the trouble in the management which caused failure in the process. After that it describes the trouble as malfunction and start remedying that cause. While processing, any unaccepted or undesirable behavior take place is called as symptom. Symptom is responsible for the trouble in process.

To understand the process let’s take an example, you want to print something so you select the ‘print’ option from the menu and fill your requirements and the process of converting a soft copy to hard copy is taking place but then, some undesirable or unexpected behavior took place and failed the whole processing. The result – Nothing is printed. Then we can use Troubleshooting process for the correction so this type of similar process failure will not take place in further processes.

Troubleshooting process is applied when there is a sudden failure in your process. From above example, you printer was working well when it was plugged but suddenly your printer stopped due to some trouble.

To understand this concept better let’s take another simple example, when the light bulb burn out, it actually happened because there was cooling and heating in its filaments and there was also some fluctuations in power supply. So it doesn’t burn out suddenly it is because of its continuous small-small failure. So when we talk about electronic machines it also takes place.

While troubleshooting process it starts from the simplest problem which could took place in process then lead to the less occur problems. In troubleshooting, troubleshooter checks each component one by one and head forward when there is no problem. It is a type of table it checks the component systematically and in an essential order. This systematical searching of problem gives it more accuracy and efficiency. There are the system in which troubleshooter checks the trouble in a failed process.

• Top-Down: Troubleshooter start checking from the Application layer to down. In this shooting technique, shooter checks the problem on the basis on user and application’s point of view.
• Bottom-Up: Troubleshooter start checking from the physical layer to up.
• Divide and Conquer: This is little bit typical to understand, in simple language – Troubleshooter start checking in the middle and the move to up or down. While using wireless or wired connectivity, it will best to use Divide and Conquer type of troubleshooting.

There will (may be) more than one error in the process. No problem, troubleshooter is made for more than one error so it can easily detect more than one error in process. Troubleshooting process is also used to find the viruses in a system. It uses in installing of cables and hubs etc.

Troubleshooting process is made to help you but if you had done all the steps and still your problem had not solved it’s better to take your laptop or computer to the repair shop. So it will be evaluated by the expert.

I hope you understand the working of Troubleshooting. If you have any question related to this topic then feel free to comment.

Hello friends today are talking about the biggest myth related to the battery life of smartphones. Is this myth really true or is it just a myth? Today are going to reveal it…

For those who are here for Single Line Answer

It is just a myth. The battery is totally depends on the usage of the user. More mAh doesn’t mean more battery life. mAh is actually a unit for measuring an ‘electric charge’. mAh means Milli-Ampere Hours.

So if you are here for complete detailed answer then you can read further for complete knowledge.

mAh – Milli-Ampere Hours

mAh is a unit of measuring an ‘Electric Charge’. Its full form is Milli-Ampere Hours. mAh is the most common and easiest way to express the quantity of small batteries like we use in our daily life and smartphones’ batteries are one of them. Its larger unit is Ah which is equal to 1000 mAh (1 Ah=1000 mAh). If the battery is of 1 Ah, this means that the battery can storage 1000 mAh of electric current in a time when it will fully charged.

A battery has a reservoir which helps to supply charge. If the battery will have to supply less charge in a time then its reservoir will last longer and drains later but if that battery will have to supply much more charge then its reservoir will gets drained quickly.

Relation Between mAh to Battery Life

If you want to calculate the exact battery’s life then you can easily find it with just a little calculation. Simply, divide the capacity of the battery by the current required by the object. For example if your battery has a capacity of 1000 mAh and your device required 500 mA to function then your device will work for two hours (1000/500=2). But if you replaced that battery with the larger one, for example 2000 mAh, in same device then that device will work for four hours (2000/500=4).

Usage is Important

The battery life any smartphone is totally depends on the usage of the user, as we say above. If you use many application simultaneously on a device then it will required more current to function that device. But if you use less applications then it will required less current to function.

To understand it let’s take an example, the average mileage of a car is depends on the weight of the car. If the weights of two cars are 2500 kg and 1500 kg then the mileage of heavy car will definitely less than the light one, if they have same engine. And it also depends on the driver. If the driving style of the heavy car will change then it may have same or more mileage than light one. So start using less application at a time to increase your battery life.

Some of the people also say that more mAh means that your camera will work for more hours. So it is actually true, you can say that if you have more mAh then your smartphone’s camera will stand for longer time than less mAh one.

We think that we are able to give all the information related to this topic. If you want to ask anything then comment below we love to hear from you and share it with your friends. If you have extra knowledge then comment below we will add this in our article.

Bitcoin is the world’s first digital currency and used as a worldwide payment system. It is cryptocurrency. Bitcoin is peer-to-peer digital currency and this transaction take place between users directly through cryptography. It was released as open-source software in 2009 by ‘Satoshi Nakamoto’. Some rumors also said that the Bitcoin was made by an unknown person and ‘Satoshi Nakamodo’ is just a group of people. The transaction works without an intermediary. Every transactions made by Bitcoin are verified by the network nodes. It is recorded in a public distributed ledger, which is known as a Blockchain. Bitcoin is completely an electronic form of money and not a physical coin; and nowadays it is using worldwide for transaction as we discuss.

Are Bitcoins Secured?

As it is an electronic currency so there is a problem of illegally copying of this currency. So preventing this, it uses network nodes in which it verifies every transactions of Bitcoin and recorded in public distributed ledger, Blockchain. For example, if I sent five Bitcoins to my friend from my Bitcoin address to my friend’s Bitcoin address. This transaction will be note and verified in a Blockchain and after the transaction, I haven’t any right on that five Bitcoins which transferred from my wallet to my friend’s wallet. So yes, we can say that Bitcoins are totally secured. But as we know technology is changing faster so we cannot give you assurance that Bitcoin are safe and always be safe.

Bitcoin Mining

Bitcoins are actually created as a reward for a process known as Mining. It can be exchanged for other countries, services, products etc. Over 100,000 merchants and vendors, in February 2015, accepted Bitcoin as a payment. And as we know that Bitcoin can also be held as an investment. Mining is a record-keeping service which is done by the use of computer processing power.

Transactions and Transaction-Fees

The transferring of Bitcoins from person to another is known as transactions. When a user sends Bitcoin by their wallet to someone else’s wallet, it uses the Bitcoin Address. Bitcoin address is a unique address of every user. 

Transaction consist one or more inputs and also one or more outputs. Since, transactions can have multiple outputs, users can send Bitcoins to multiple recipient in one transaction. If any input satoshis not accounted for in the transaction outputs become the transaction fees.

Transaction fees are optional. Transaction fees are based on the storage size of the transaction generated.

How to Get a Bitcoin Address?

In order to send or receive Bitcoins you will need to have your unique Bitcoin Address. If you want your unique Bitcoin address, you either download the bitcoin client or by getting an online wallet. There are two most popular Bitcoin Clients are:

• Bitcoin-qt
• Multibuilt

The main difference between these two clients is just the size of their blockchain that you need to be downloads. You need at least 10 Gigabyte (or 10 GB) of free hard disk in your system, to download the Bitcoin.

Where will your Bitcoin Stored?

When you downloaded the Bitcoin from one of the above client, after installing you will see the file called wallet.dat. The Bitcoins will also be stored in online wallet. There are some of the popular, specialized and safe websites in which you can store your Bitcoins securely.

If you want to store small amount of Bitcoins then online wallet is the best option for you. By using the online wallet you can easily use your Bitcoins for purchase. Bitcoin exchange is considered much safer place than online wallet.

Why You Have to Trade Bitcoins?

Bitcoin available 24/7

As you know that the stock markets closed in limited time but if you use Bitcoin so you will trade anytime. Unlike stock markets, Bitcoin have no official exchanges. There are thousands of exchanges in Bitcoin. There is no official Bitcoin price because there is no Bitcoin exchange.

Bitcoin is World wide

Bitcoin is not a physical currency but it is an electronic currency. It is currently increasing. The popularity of Bitcoin is extremely high. By using Bitcoins, you can trade anywhere in the world. No country actually declared that Bitcoin is Illegal. So until countries are not declaring this currency illegal, so you can use it anywhere.

How to Trade Bitcoin?

There are many websites for trading Bitcoins but we will not taking one website to explain. We simply explain you without any specific site. If you want to choose a website then simply search it and be sure to check it totally before signing up.

Open an Account

This step takes only few minutes. When you decide the exchange which you want to use for your Bitcoin, just sign up and make an account. You will need an IG trading account because you cannot buy or sell Bitcoin, you will not need an exchange account. You will need to confirm your account by email. Once you logged in and verified your details you will access your account.

Research

Before buying or trading the Bitcoins: firstly do research. Check the price of Bitcoins and news related to Bitcoins so you will get to know about the universe of Bitcoins. Don’t our, read others blog also related to this topic. May be you get something more. The point we want to tell you is to research as much as you can. Because it is new universe, so any feature can affect its price. You can observe the charts or many facts related to Bitcoins.

Strategy

After observing the all facts and figures related to new Bitcoin, you can make a strategy for trading. The only person who can make your strategy powerful is – You. You are the one who can understand your thinking better than anyone. Plan your strategy on your plans with keeping the facts and figures in your minds.

Risk Management

Before trading with Bitcoins, make a backup plan. It is a game of Profit and loss and there is no guarantee that you always win so always keep in mind that you can also lose and if you lose how you could deal with it. Never invest more than required on specific investment.

Benefits of Bitcoins

There are some benefits of Bitcoins:

Safe

Bitcoin is actually considered a safe currency because no one can steal it from you. Some website like PayPal allow you to t claim your money back but it takes long time.

Simple

Bitcoin is very simple currency. You can use it electronically and worldwide.

Easy to Carry

You can carry your electric currency easily either in wallet or online. And you can use it anywhere and anytime for purchase.

Risks of Bitcoins

As in every investment there are some risks in Bitcoin:

Easy to Lose

You can easily lose your Bitcoin. Unlike Credit card, it you CD is stolen then there is a chance that you will not lose you money but if your Bitcoin wallet gets hacked then you cannot get it back.

Trading is Actually Hard

Bitcoin trading is getting harder and harder at every moment and people seem it difficult to trade in this fast changing investment world.

Newness

Bitcoin trading is new and most of the countries are still not sure that Bitcoin is safe or not, so this may be the biggest risk in Bitcoins.

Lack of Stuff

Yes, you cannot buy everything by Bitcoin because there are not much shops which accept BItcoin for payments.

 

Risk and Benefit Both

There is one feature which act as a benefit in Bitcoin trading and also a risk. It is:

Untraceable

• (Benefit) You don’t need to afraid that some organization or someone is tracing your Bitcoins because it is untraceable. This is the best point for governments, so they will never be traced by anyone.
• (Risk) If Bitcoin is start using in the selling and buying of Drugs then it will become very tough for the government to track those authorities who are smuggling because Bitcoins are untraceable.

Last

After all, I think you understand everything about Bitcoin Trading. So if you like this article, then share it to your friends and comment below if you have any question related to this topic…

Visualizable questions in science and medication stretch out over a tremendous scope of scale, from singular particles and cells through the assortments of tissue and interstitial interfaces to finish organs, organ frameworks, and body parts.

The act of pharmaceutical and investigation of science have dependably depended on perceptions to contemplate the relationship of anatomic structure to biologic capacity and to identify and treat sickness and injury that aggravate or undermine typical life forms. Generally, these representations have been either immediate, through surgery or biopsy, or aberrant, requiring broad mental remaking. The potential for progressive development in the act of drug and in biologic examinations lies in coordinate, completely immersive, constant multi tangible combination of genuine and virtual data information streams into on the web, ongoing perceptions accessible amid real clinical methodology or organic analyses. In the field of logical representation, the expression "four dimensional perception" as a rule alludes to the way toward rendering a three dimensional field of scalar esteems.

"4D" is shorthand for "four-dimensional"- the fourth measurement being time. 4D perception takes three-dimensional pictures and adds the component of time to the procedure. The progressive abilities of new three-dimensional (3-D) and four-dimensional (4-D) restorative imaging modalities alongside PC reproduction and rendering of multidimensional medicinal and histologic volume picture information, hinder the requirement for physical analyzation or conceptual gathering of life systems and give capable new chances to therapeutic finding and treatment, and in addition for organic investigations.In complexity to 3D imaging demonstrative procedures, 4D enables specialist to envision inside life structures moving continuously. So doctors and sonographers can identify or preclude any number of issues, from vascular inconsistencies and hereditary disorders. Time will uncover the significance of 4d perception

4D-The Modern Dimensions

"4D" is shorthand for "four-dimensional"- the fourth measurement being time. 4D representation takes three-dimensional pictures and adds the component of time to the procedure.

As opposed to 3D imaging symptomatic procedures, 4D enables specialist to envision inside life systems moving progressively. For instance: Movement examples of embryos enables conclusions to be drawn about their advancement; increment of precision in ultrasound guided biopsies on account of the representation of needle developments continuously in every one of the 3 planes. So doctors and sonographers can identify or preclude any number of issues, from vascular oddities and hereditary disorders

3D Gives Life to 4D

Bolted inside 3-D biomedical pictures is critical data about the items and their properties from which the pictures are inferred. Endeavors to open this data to uncover answers to the riddles of shape and capacity are framed in the area of picture preparing and perception. An assortment of both standard and advanced techniques have been created to process (alter) pictures to specifically upgrade the perceivability and quantifiability of wanted question highlights and properties. For instance, both authenticity protecting and observation adjusting ways to deal with picture show have fundamentally propelled the down to earth handiness of 4-D biomedical imaging.

Numerous hazardous maladies or potentially personal satisfaction tribulations still require physical intercessions into the body to decrease or expel sickness or to reduce destructive or agonizing conditions. In any case, insignificantly intrusive or noninvasive mediations are presently inside achieve that adequately increment doctor execution in capturing or curing illness; lessen chance, agony, difficulties, and reoccurrence for the patient; and diminishing human services costs. What is yet required is engaged lessening of later and proceeding with propels in representation innovation to the level of training, so they can give new apparatuses and systems that doctors ''must have'' to treat their patients and enable researchers in biomedical investigations of structure-to work connections.

Shaping a picture is mapping some property of a protest onto picture space. This space is utilized to imagine the question and its properties and might be utilized to portray quantitatively its structure or capacity. Imaging science might be characterized as the investigation of these mappings and the advancement of approaches to better comprehend them, to enhance them, and to utilize them gainfully. The test of imaging science is to give propelled capacities to procurement, handling, representation, and quantitative examination of biomedical pictures to increment considerably the loyal extraction of valuable data that they contain.

Idea Of 4D Visualization

In the field of logical representation, the expression "four dimensional perception" for the most part alludes to the way toward rendering a three dimensional field of scalar esteems. While this worldview applies to a wide range of informational collections, there are likewise utilizes for imagining information that compare to genuine four-dimensional structures. Four dimensional structures have ordinarily been envisioned by means of wire outline techniques, however this procedure alone is normally lacking for a natural comprehension. The perception of four dimensional items is conceivable through wire outline techniques with broadened representation signs, and through beam following strategies. Both the strategies utilize genuine four-space seeing parameters and geometry.

The beam following methodology effortlessly settles the concealed surface and shadowing issues of 4D questions, and yields a picture as a three-dimensional field of RGB esteems, which can be rendered with an assortment of existing techniques. The 4D beam tracer likewise bolsters genuine four-dimensional lighting, reflections and refractions. The show of four-dimensional information is generally expert by allocating three measurements to area in three-space, and the rest of the measurement to some scalar property at every three-dimensional area. This task is very able for an assortment of four-dimensional information, for example, tissue thickness in an area of a human body, weight esteems in a volume of air, or temperature dispersion all through a mechanical question

4D Image Warping

For heartily measuring worldly morphological cerebrum changes, a 4D picture distorting component can be utilized. Longitudinal steadiness is accomplished by considering all fleeting MR pictures of an individual all the while in picture distorting, instead of by separately twisting a 3D layout to an individual, or by distorting the pictures of one time-point to those of some other time-point. Also, picture includes that are reliably perceived in unequaled focuses direct the twisting system, though spurious highlights that show up conflictingly at various time-focuses are dispensed with. This misshapening methodology altogether enhances power in identifying anatomical correspondences, subsequently delivering smooth and exact estimations of longitudinal changes. The trial comes about demonstrate the huge change of 4D distorting strategy over past 3D twisting technique in measuring unpretentious longitudinal changes of cerebrum structures.

Strategy:

4D-Hammer

It includes the accompanying two stages:

Rigid arrangement of 3D pictures of a given subject gained at various time focuses, with a specific end goal to create a 4D picture. 3D-HAMMER is utilized to build up the correspondences between neighboring 3D pictures, and after that adjust one picture (time t) to its past time picture (t-1) by an inflexible change computed from the built up

correspondences.

Hierarchical misshapening of the 4D map book to the 4D subject pictures, through a various leveled quality based coordinating technique. At first, the misshapening of the map book is affected basically by voxels with particular characteristic vectors, in this way limiting the odds of poor matches and furthermore diminishing computational weight. As the disfigurement continues, voxels with less unmistakable characteristic vectors step by step pick up impact over the twisting.

Conclusion

Propelled therapeutic imaging innovation permits the procurement of high settled 3D pictures after some time i.e.4D pictures of the thumping heart. 4D representation and PC bolstered exact estimation of therapeutic markers (ventricle volume, discharge portion, divider movement and so forth.) have the high potential to significantly streamline comprehension of the morphology and elements of heart cavities, at the same time lessen the likelihood of a false determination. 4D representation goes for giving all data helpfully in single, stereo, or intuitively turning enlivened perspectives.
