A computer is a system that is capable of performing a given, well-defined, variable sequence of operations.
In short, this is a super gadget. Many different functions and programs can be performed using a computer. I find the computer to be a very useful device. But when working with it, you need to follow the safety rules. Do not sit close to the screen, it is advisable to remove everything that can spoil or harm the computer, etc. But the computer is not very compact and does not fit everywhere. What is sometimes frustrating. The harm of a computer is that if you sit at it for a very long time, you can get a curvature of posture and become addicted. So use your computer in moderation!
We live in the world full of technological devices of all sorts. One of the most popular devices is the computer and it is important to know hoe to use it.
First of all you need to know that a basic computer system has two components: hardware and software. Hardware means components that can be touched by your hand: a monitor, a keyboard, a mouse and a system unit with a motherboard, memory modules and a disk drive inside. Software means instructions, programs, data and protocols.
To start working you need to do the following:
1. Press the power button and let the computer boot up.
2. Left-click on the Start button in the bottom right corner of the screen. This will bring up a menu of programmes.
3. Choose a programme you need and click on it. To work with programmes you need to click different menus and enter text by typing it from the keyboard.
4. If you need to search for some information, open a browser and type your question, then click Enter and you will see the search results with links to web-pages.
5. When you finish using your computer, it is important that you shut it down properly. You need to make sure that all running programs are stopped. Otherwise you may lose important data. Then click on the Start button and click on "Shut down".

In summer iwould like to visit Astrakhan. The fact is that i like travelling by car. I have already visited several cities and towns: Minsk, penza, tver, tula,kaluga. I think that it is very interesting to travel by car: you can stay in different hotels, eat in local restaurants and see different places. My trip to Astrakhan will take me two days to get there. I hope to visit historical places there and to taste a watermelon and vobla!
