It is a little difficult to explain, but in a few lines, a computer is a machine composed of two different parts; a physical one called ''Hardware'', that executes any command or instruction, and ''Software'', the non physical part that includes the instructions and data of what the hardware has to do
Basically, you have a screen where you can see the operative system an the programs installed on it, a mouse, that allows you to move and select things, and also a keyboard use for writing.
The first time that I used a computer was when I was 5-6 years old. My uncle taught me how to use it and then showed me the MAME32, a game emulator of classic arcade games. Since then I became an addict to computer games and computers.
I never had my own computer, until 2015 when my grandmother gave me my first laptop. I spent a lot of time doing different things, like watching videos, playing games, reading books and more. Now I don't have enough time to spend on my computer, but I can spend 6-8 hours if I have time.
I like it because you can do a lot of things on it and the most important thing, is the best way to have access to the internet.
Without my computer my life would be more difficult because I would have less access to information, and I would have to buy a lot of things that with my computer are free and easy to get.
