III. TRANSLATE THESE SENTENCES INTO VIETNAMES

1. A standard computer system consists of three main sections: the central processing

unit (CPU), the main memory and the peripherals.

2. The function of CPU is to execute program instructions and coordinate the

activities of all other units. it is the “brain” of the computer.

3. The nerve centre of a microcomputer is the central processing unit or CPU. This unit is built into a single microproceesor chip an intergrated circuit which executes program instructions and supervises the computer’s overall operation. 4. Information is processed and stored in computers as electrical signals. A computer

contains thousands of electronic circuits connected by switches.

5. 1s and 0s are grouped into eight digit codes that typically represent characters

( letters, numbers and symbols). Eight bits together are called a byte. In order to avoid astronomical figures and sums in the calculation of bytes, we use units such as kilobytes, megabytes and gigabytes. One kilobyte is 1,024 bytes . One megabyte is equivalent to 1,024 KB, and one gigabyte is 1,024 MB.We use these units (KB, MB, GB) to describe the RAM memory, the storage capacity to disks and the size of any application or document.

7. Ram (random access memory) is temporary i.e. Its information is lost when the computer is turned off. However, the Rom section ( read only memory) is permanent and contains instructions needed by the processor.

8. The size of RAM is very important if we want to increase the performance of a

computer when several applications are open at the same time or when a document is very complex.

9. Information stored on magnetic disk can retrieved faster than if that same

information were on tape.

10. A program written in one of the high level languages is called a source program. 11. The extension of internal storage in order to increase the capacity of primary

memory is called virtual storage.

12.The surface of a floppy disk is divided into concentric circles or “tracks”, which

are then divided into “ sectors”.

13.“Access time” is the time it takes your read/ write head to find any particular

record and “data transfer rate” is the average speed required to transmit data from a disk system to the Ram.

14. The total number of pixels in which the display is ivided both horizontally and

vertically is known as the resolution.

15. If you work in an office with a large number of computers, don’t sit too close to

the sides or backs of the monitors.

16. The nerver centre of a microcomputer is the centre processing unit or CPU. The

unit consits of three main parts:

The control unit

The arithmetic logic unit The registers

17.Software is information in the form of data and programs, hardware is the electronic and mechanical parts that make up a computer system 18. The registers, which are high speed units of memory used to store and control information. There are two registers. They are program counter (PC) and instruction register (IR) . Program counter which keeps track of the next instruction to be performed in the main memory, instruction register (IR) which keeps the instruction that is being executed.

19.According to the writer, The importance of “pixel resolution” decides the quality

of image.

20.When you save a file, the operating system moves the read/ write heads of the disk drive towards empty sectors, records the data and writes an entry for the directory. 21. When you open the file, the operating system looks for its entry in the directory on the disk, moves the read/ write heads to the correct sectors, and reads the file into the RAM area.

22.If you only use word processing programs, you will need less storage capacity

than if you use CAD.

23.Microcomputers make use of two types of main memory: RAM and ROM, both

contained in electronic chips connected to the mainboard of the computer. 24.RAM is the working area of the computer, that is the basic location where the

microprocessor stores the required information.

25.We use these units (KB, MB, GB) to describe the RAM memory, the storage

capacity of disks and the size of any application or dorcument.

The mouse also issues instructions to the computer very quickly Mice are so widely used in graphics applications.

26. the advantages of the computer mouse over the keyboard are it is very quick way to move around on a screen

28. Can a computer solve problems? Definitely not. It is a machine that carries out the procedures which the programmer gives it. It is the programmer then who solves the problems.

27 . Source programs written in high level languages have to be changed to machine code before the computer can operate on them.

30. Constructing an algorithm is the basic step in solving a problem. 31. Punched cards are the only way of transferring the program to the computer

32.

29. There are six steps to solve a problem. Step 1: The programmer must be define the problem clearly. Step 2: The programmer must formulate an algorithm. Step 3: The programmer must translate the algorithm into a computer program. Step 4: The programmer must then keypunch the program or give the coding sheets to the keypunch operator to do it. Step 5: The program must then be tested. Step 6: Add the data to the program and run the job completely.

33. An algorithm is a sequence of instructions used to solve a problem. 34. All high level programs must be translated to machine code before the

memory. If the data is not added to the program, the computer cannot perform calculation.

computer can execute them.

35. Different high level languages suit different problems. 36. 37. A computer is a useless machine if its capabilities and limitations are

It is a must for a programmer to be helped to understand machine code.

38. A computer usually solves problems by doing some mathematical and

unknown.

39. Computers do not usually make mistakes unless they break down. 40. A computer is useless without a programmer to tell it what to do.

3. Software is Information in the form of data and programs. 4. Hardware is the electronic and mechanical parts that make up a computer

process the data and give the results.

5. There are three sections. They are CPU, main memory and peripherals. 6. The function of CPU is to execute program instructions and coordinate the

system.

8. peripherals are the physical units attached to the computer. 9. There are three parts in peripherals.They are storage devices, input devices and

activities of all other units. the function of main memory holds the instructions and data which are being processed by the CPU.
