IV. Монологическая речь.

T.: What is a computer?

P.: Computer is a device.

T.: Who can tell us some words about computer?

Примерный текст пересказа.

Computer is a device for processing information. Computer has no intelligence by itself and is called hardware. A computer system is a combination of four elements.

  • Hardware
  • Software
  • Procedures
  • Data /Information

Software are the programs that tell the hardware how to perform a task. Without software instructions, the hardware doesn't know what to do.

The basic job of the computer is the processing of information. Computers take information in the form of instructions called programs and symbols called data. After that they perform various mathematical and logical operations, and then give the results (information). Computer is used to convert data into information. Computer is also used to store information in the digital form.

T.: How do we translate the words ‘’hardware’’ and ‘’software’’?

P .: ’’hardware’’- оборудование, устройство,’’software’’-программа.

V. Чтение, письмо, устная речь.

VII. Чтение с общим пониманием прочитанного.

Open your books at page 170(учебник английского языка под ред. А.П. Агабекяна) Let’s read the text about computer operations one by one.

The ability to follow the program sets computers apart from most tools. However, new tools ranging from

COMPUTER OPERATIONS.

Much of the processing computers can be divided into two general types of operation. Arithmetic procedures. Early computers performed mostly arithmetic operations, which gave the false impression that only engineers and scientists could benefit from computers .Of equal importance is the computers operations are computations with numbers such as addition, subtraction, and other mathematical ability to compare two values to determine if one is larger than, smaller than, or equal to the other. This is called a logical operation .The comparison may take place between numbers, letters, sounds, or even drawings The processingofthe computer is based on the computer’sability to perform logical and arithmetical operations.

Instructions must be given to the computer to tell it how to process the data it receives and the format needed for output and storage. The ability to follow the program sets computers apart from most tools. However, new tools ranging from typewriters to microwave ovens have embedded computers, or build-in computers .An embedded computer can accept data to use several options in it’s program, but the program itself cannot be changed. This makes these devices flexible and convenient but not the embedded computers itself.

Exercise 1. Question for general understanding:

  1. In what two major parts could be computer operations divided?
  2. What are arithmetic operations and what are logical operations?
  3. What are embedded computers?
  4. What modern devices have embedded
  5. 5What makes computer so different from other tools?

Exercise 2. Which sentences are true and which are false?Read and give the correct answers.

  1. Arithmetic operations are operations with numbers-subtraction and division.
  2. Early computers gave false impression about their capabilities.
  3. Logical operations are computer’s ability to compare two values.
  4. The major difference between the computer and tools lies in the flexibility of the program.
  5. Microwave oven’s program is flexible and could be changed because of the embedded computer.

Exercise 3.

T.: Complete the following sentences.Work individually,consult the text.

  1. The computers ability to compare two values to determine if one is larger than,smaller than or equal to the other is called…. .
  2. New tools ranging from typewriters to microwave ovens have embedded computers or……….computers.
  3. ……….are computations with numbers such as addition ,subtraction and other mathematical procedures.

Exercise 4.

T.: Arithmetic operation deals with numbers.Translate the sentences from Russian into English .Read the numerals correctly .

  1. There are two formats for floppy disks 5.25’ and 3.5’.(‘-inch-дюйм)
  2. 3.5’ disks are formatted 1.4 MB are widely used.
  3. The major chip is known as the 8255.

VIII .Аудирование .

T.: In this dialogue there are some numbers too.Listen to it and find the right variant .Work individually.

The History Of the Internet .

Presenter: Welcome to ‘’Future Now’.Today we are going to discuss the Internet with Dr .Jennifer May from Manchester University .Dr .May ,how did the Internet begin?

Dr.May:Well,it’s strange but the Internet was started by the military .In the 1960s the Pentagon were worried about communications after a nuclear war .And in 1969 they thought of linking computers into a network so that if one part of the network was destroyed ,other parts could continue working.

Presenter: And then scientists started to use the network ,right .

Dr .May: Yes ,people in universities all over the world began to use the network to share ideas .They used it for work and for fun .In the 1980s,people started calling it the Internet.

Presenter: Then it was in the mid-1990s that the Internet really began to grow fast.

Dr .May : Yes ,now the Internet is important for entertainment ,e-mail ,playing games and getting information.
