Computer are used for many purposes such as to search for jobs, games, banking, learning, social networking, and much more is there to access over internet. Anyone who possesses a computer must have some knowledge about the different components involved in it.

- Central Processing Unit (CPU): 

This is the unit which is responsible for the running of the system. It contains all the necessary components required to run the system properly like hard drive, motherboard, processor, sound card, CD drive, fan, optical drive, RAM. You can modify these components in order to improve the performance.

- Monitor: It is a displaying unit that displays all the activities of CPU.

- Mouse: It is a device to point the items, closing and opening of program is easier with this device.

- Keyboard: It is used to execute commands and other tasks like input letters.

Ways to Stay Up to Date with Latest Software

With the latest developments of technology, it is almost impossible to keep the pace with this technological development, especially with computer technology. It is not just confined to some class or some people, it has become a major part of all the industries, educational institutions, banking sector and so on. Almost all the major work has been done through computers. 

Today, most of the transactions are made online. Computer are used for many purposes such as to search for jobs, games, banking, learning, social networking, and much more is there to access over internet.  New computer software are introduced each day and many old software are updated into new versions due to which it is sometimes become a hard task to operate a file or program with old versions. Here are few ways given to keep you up to date with latest version of software.


- Turn Updater On:

One best way to cope with this problem is to turn your updater on. It recognizes the new software and automatically downloads the available updates to your system. Many of the computer programs are now coming with automatic update option.

- Check the Internet: 

you can search on the internet for your required software update.New computer software are introduced each day and many old software are updated into new versions due to which it is sometimes become a hard task to operate a file or program with old versions.

- Check your Retailer: 

For programs and software that are licensed, it is better to contact your software retailer to have new or updated versions.

- Magazines: 

There are so many magazines and journals available in the market covering the recent technological development in computer and its different software applications. You can take help from them.

- Watch: 

There are some channels which include informative programs based on different software applications and their specifications and requirements. They can be helpful to know about recent applications.

Before selecting any software, it is important to see whether your PC (Personal Computer) has the required specifications or not. It is not recommendable to use those applications, which show higher specifications than your PC has. Those applications will not work properly or there are chances that your system get slow.

Systems Software

Systems Software are applications that are designed specifically for running the hardware on a personal computer and are used to maintain a platform for Application Software to be used. This means that systems software is designed to communicate with the internal parts of your computer such as the hard drive, RAM, ROM, cache, microprocessors, etc. so that the user doesn't have to. It contains all of the drivers necessary for this type of communication and, in the simplest sense, it is the interface between the user and the hardware.
The Operating System (OS) is not only one of the most important systems software on a computer, but is also the most frequently used. It is the software that runs in the background and brings the separate physical parts of the computer together in order to provide the seamless stream of activity that a user experiences. Some of its responsibilities include the transfer of data between the memory and disks (on the hard drive) as well as providing the information needed to display icons, text, cursors and other visible necessities on the display screen. 
This display is called the graphical user interface (GUI) and is entirely the result of the OS on the computer. This can be compared by viewing the differences between the Ubuntu OS and the Mac Snow Leopard OS. The icons between the two are positioned differently and they look different too. The Mac OS and GUI tends to have a more three dimensional aspect to it where Windows tends to appear more flat. It should also be remembered that the operating system conducts itself independently of both the user and any application software being used. 
This means that it is not directly dependent on the user or other programs in order to operate. Some other systems software would include BIOS and other device firmware. These help the user interact with other utilities such as diagnostic tools, language translators, data communication programs, as well as data management programs.
