OPERATING SYSTEMS QUESTIONS

-What's an operating system? It is the most important program in a computer that allows the computer to run other programs. It obeys commands from the keyboard or mouse and desplays information on the screen. It also takes a large part in organizing files and it controlls peripheral devices. It is also responsible programs not inerfering with each other and the computer's security against viruses. For more information or other definitions on technological terms, webopedia is a very good site. Check it out here: http://www.webopedia.com/

-What is the difference between an OS, an application and an app? an OS is short for operating system which unlike an application is the program that runs other. An application is installed into the OS and has a much simpler interaction with the computer than an OS. And an app is just an abbreviation for application.

-Write a brief comparative report between Linux, Windows and Mac.

Both Mac and Linux are very good at preventing viruses but when you have a Windows it is recommended to have an antivirus program. Both Linux and Windows can be intalled on many different kinds of computers but on the other hand, Mac can only be installed on Apple computers, but in general, Mac works more efficiently and has less glitches (it is more reliable). When regarding price, Linux is the best since it is free and Mac is the most expensive of the three.Finally, when we look at compatibility, Windows is the best since it is what most people have.

-Why do you use the operating system that you use? (3 reasons)

The operating system I have always used is Windows. The first and main reason for this is because I find it very user friendly and not complicated at all to use. The second reason is that since it's the operating system that most people have, the programs on it are all similar and therefore there are less compatibility problems. The third and final reason I use it is because it is easy to install and download programs on it quickly.
