Unit 8: Computers in our lives


The computers
Computers are a very important part of our lives. They tell us about delays to transport. They drive trains, analyse evidence and control buildings. Did you know that 60% of homes in Britain have got a PC?
A computer is a programmable machine designed to sequentially and automatically carry out a sequence of arithmetic or logical operations. The particular sequence of operations can be changed readily, allowing the computer to solve more than one kind of problem.
In our live are very important the computers because are in libraries, in the police station and in the school.
Smart home
The smart home is now a real possibility. It will become very common. A central computer will adjust the temperature, act as a burglar alarm and switch on lights ready for you to come back home. If the temperature outside changes, the smart home will adjust temperatures levels inside. The computer will also close the blinds when it gets dark or to stop too much sun from entering a room. And if you want to eat when you get home, the computer will turn the oven on for you!
I had a computer when I was 10
In a survey, 44 per cent of young people between 11 and 16 said their PC was a trusted friend. Twenty per cent said they were happier at their a computer than spending time with family or friends.
