Computer Software

There are many computer software programs; for example, pc monitoring software and computer applications. All computers run on an operating system. What is the definition of operating system? What are the best operating systems?

The definition of operating system is important in relation to software: software needs to run on an operating system. Your operating system is necessary: it recognizes input from the keyboard; sends output to the display screen; it keeps track of directories and files on your system disk; and it controls other devices such as the printer, disk drives, the mouse and more.

Today's best operating systems offer pros and cons for each system:

• the most widely recognized operating system is Windows by Microsoft: Windows 7 is the newest edition; Windows Vista; Windows XP. It is used globally for business and personal systems, relatively expensive, most common system for gamers, and often targeted by hackers/viruses;
• Linux - is usually available for free but requires a more advanced system knowledge; limited software programs available although experienced users can access other programs through a compatability layer;
• and Mac OS X - considered reliable and is well-loved by its user community; runs only on MacIntosh/Apple systems.

Got your computer all built, your operating system installed, and now you need some computer software to keep things running smoothly? Here is a list of free or inexpensive software that will help you do that.

There are a ton of free computer software applications out there these days. I have tried to gather together the most useful of them. I have concentrated on applications that will be the most useful to you in the following categories:

• Computer Monitoring Software
• Utilities and Benchmarking
• Computer Applications

My goal here was to collect together some of the most useful computer programs and free applications. I spend a lot of time on the web, and so come across a lot of these on a daily basis. I have kept the list to those that I have used, or those that others I know have used. So jump in, browse around and find the software that you need.

Computer Monitoring Software

This category includes programs that will monitor the health of your computer. Programs like virus scanning, firewalls, and anti-spyware are all in here.

Protect Your Computer

Utilities and Benchmarking

Computer utilities are smaller programs that allow you to get detailed information on your computer and monitor things like CPU temperature and fan speeds. Along with that is benchmarking that will report your computer's speed and allow you to compare it against other similar computers.

Inspect Your Computer

Computer Applications

Computer applications are programs that allow you to do various tasks; word processing, spreadsheets, burn a DVD - you will find them all here.
