Activity 2.Answer  the  following questions.

1 What kind of  machineis  a computer ?

Computer is a machine that performs calculations and processes information with astonishing speed and pre­cision. A computer can handle vast amounts of information and solve complicated problems. It can take thou­sands of individual pieces of data and turn them into more usable information—with blinding speed and almost unfailing accuracy. 

2. 
   What can the most powerful computers do? 
   

The most powerful computers can perform billions of calculations per second.



3 What tasks do computers handle in business, education, manufacturing, transportation, and other fields? 

Computers handle many tasks in business, education, manufacturing, transportation, and other fields. They provide scientists and other researchers with a clearer understanding of nature. They give people who work with words an effective way to create documents. They enable designers and artists to see things that have never been seen before.. 
4 How are computers changing people's views of the world?

Computers produce new infor­mation so quickly and accurately that they are changing people's views of the world. For these and other rea­sons, the computer is one of the most interesting and important machines ever invented. 
5 What computer is the most common type of computer? 

The most common type of computer, by far, is the digital computer. Digital means having to do with num­bers. Digital computers perform tasks by changing one set of numbers into another set.
6. What is the function of digital computers?

All data - numerals, pictures, sounds, symbols, and words—are translated into numbers inside the computer. 
7. What parts do all digital computers have?

Digital computers are so widespread that the work of computer alone almost always refers to a digital computer. The largest digital computers are parts of computer systems that fill a large room. The smallest digital com­puters—some so tiny they can pass through the eye of a needle - are found inside wrist watches, pocket calcula­tors, and other devices.
8. What are the functions of the memory and the processor?
All digital computers have two basic parts—a memory and a processor. The memory receives data and holds them until needed. The memory is made up of a huge collection of switches. The processor changes data into useful information by converting numbers into other numbers. It reads numbers from the memory performs basic arithmetic calculations such as addition or sub­traction, and puts the  answer  back into the memory. The processor performs this activity over and over until the desired result is achieved. Both the memory and the processor are electronic— that is, they work by sending electrical signals through wires.
