People use computers in many ways. These devices are multi-purpose tools and many of us can't imagine live without them. I'm the one of them. Mostly I use my computer in my free time for entertainment and communication and sometimes in my study.
I've chosen to study informatics and that's why computer is necessary for me. First of all I'll need it to program. I learn programming languages such as C++, Java and others. Also I use computer for solving various mathematical tasks. It is quite useful in solving very difficult propositions. For these purposes are used special mathematic programs such as Mathematica, Mathcad, MatLAB. I must say I need computer to make assignments of maths, english, and other subjects. Furthermore I work with application programs. For example, I use word processor to write papers and essays, I make presentations using special programs. Computer also is needed for me to find the information I need.
For this purposes I use the Internet. I have some dictionaries, which I use for translating words and studying English.
But I use computer not only in my study but also for entertainment. Browsing the internet, I find much information about things that interest me. Chatting on IRC is very practical. I chat with my friends without spending much money, because I don't have to call them. Moreover, I am trying to work with media editing programs for photos and videos, but I do it very rarely.
So as you can see computer has become quite essential part of my life. I can use it in many ways.
