Definition of Operating System: And The Relationship to 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 (also known as applications or 'apps'): software needs to run on an operating system (OS).
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.
If you are what's known as a 'power user' (someone who works hard and long on their system and uses a variety of applications), you will likely already have a favorite OS that is robust enough for your specific needs. If you are a regular and/or 'light' user, then test a couple of options at your local computer store to see what works best for you.
Today's best operating systems offer pros and cons for each system:
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:
Know of a great free application or utility that I don't have listed? Let me know and I'll get it added in.
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.
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.
Computer applications are programs that allow you to do various tasks; word processing, spreadsheets, burn a DVD - you will find them all here.
Software for your system is more than the standard office type of product (such as a word processor, a spreadsheet program and more).
You also need to consider the software that operates your system and that helps it to operate efficiently (and to troubleshoot it when it doesn't run).
Make sure that you develop a working knowledge of what's available in these areas: operating systems to run your computer; monitoring software to protect your computer; utilities for managing and reporting on the functioning of components, such as the CPU and HD; benchmarking which will compare speed, BIOS and hardware details to other systems; and applications (such as a word processor) to run on your computer.
