Information Well

This time we'll be learning about something which has already been in the market for a long time but still many of us doesn't understand its importance or how it is significantly better than its counterparts. That new thing is Solid State Drive (SSD). SSD is just another storage media like your pendrive and harddisk but it is way faster than either of them. In this post, we will learn what really makes an SSD faster than other storage media and how it can change our life forever. What really is an SSD ? What makes SSD better ? Role of SSD in laptops What really is an SSD ? SSD is a flash device just like pendrives, micro sd cards and embedded storage of our mobile phones. A flash device is basically made of transistors and semiconductors as compared to harddisk which has magnetic disk and moving parts. I may introduce some heavy terms here which may not make sense to you much but keep reading. So like i was saying, flash devices have ...

In the previous article , we discussed about cache and its properties. We also learnt some concepts and terminology related to cache. If you haven't read that article, i will recommend you to read that article first. This article contains many terms which i've discussed in that article. In this article, we will learn cache replacement strategies, cache mapping techniques and cache writing techniques. Below is the index of this complete cache tutorial.

Some of you may have already heard about the computer cache in your curriculum or some of you may have not. But this article is intended for all of those who want to understand cache concepts. The next part of it consists of developing a cache simulator using C programming language. I believe that this article will give a clear insight of cache and how it works. So lets see what we will be learning in this series of articles.

Lesson 1 Lesson 2 Lesson 3 Lesson 4 Learn Git : Lesson 1 Why Git or any VCS Image from git-scm Version control system is a software which maintains the records of changes done to a project and also the states of the project which you can switch anytime. As a programmer, it sometimes happens to me when i write a piece of code and it works but when i try to optimize it then it gets broken. Also i could not be able to traceback the changes and get my working code back. If this happens to you also then you might undo tens of times to get back the previous code. But what will you do if your project contains multiple files with hundred lines of code in each file. If you now brong some changes to more than one file then its not easily possible to get back the working code. Here comes the importance of a version control system. In a VCS, you can save the current state and continue to work on a different state but it doesn't mean that vcs creates a copy of the current state....

A USB port is a standard cable connection interface on personal computers and consumer electronics. USB ports allow stand-alone electronic devices to be connected via cables to a computer (or to each other). USB stands for Universal Serial Bus, an industry standard for short-distance digital data communications. USB allows data to be transferred between devices. USB ports can also supply electric power across the cable to devices without their own power source. Both wired and wireless versions of the USB standard exist, although only the wired version involves USB ports and cables. What Can You Plug Into a USB Port?: Many types of consumer electronics support USB interfaces. These types of equipment are most commonly used for computer networking: USB network adapters USB broadband and cellular modems for Internet access USB printers to be shared on a home network For computer-to-computer file transfers without a network, USB keys are also sometimes used to copy files betwee...
