A, B, C are true II/ THE STATEMENTS BELOW ARE TRUE (T) OR FAULT (F): Computers are electronic machines that process information. The Ram capacity can’t be expanded by adding extra chips. The Ram capacity can be expanded by adding extra chips. All information stored in the Ram is temporary. All information stored in the Ram is permanent. A CPU contains thousands of electronic circuits connected by switches. We use KB, MB, GB to describe the Ram memory, the storage capacity of disk We can put information into Rom. We cannot put information into Rom. Information is processed and stored in computer as electrical signals. Sometimes, computers are use three or four digits instead of two digits. 12. If we don’t want to use this information later on, we don’t have to save it and store it on a disk. If we want to use this information later on, we don’t have to save it and store it on a disk. Ram, Rom and secondary storage are the components of the main memory. Information can not be processed by the microprocessor if it is not loaded into the main memory The speed of the microprocessor is measured in megahertz. One MHz is equivalent to one million cycles per second. “Seek time” refers to the average time required for the recording heads to move and access data. The cathode ray tube of monitor isn’t similar to that of a TV set. A mouse is smaller than a pack of cards but its function is powerful. The high resolution gives us a sharp image. The disks must be initialized or formatted before information can be recorded onto it. Information in the Rom can be changed and are erased when the power is turned off. Information in the Rom cannot be changed and are erased when the power is turned off. Mice can’t do difficult thing in graphic applications. Lap top use a flat liquid crystal display instead of a picture tube. If you use multimedia applications, you need the same storage capacity as required for word processors. A computer cannot do anything until it has been programmed. A computer is a useless machine if its capabilities and limitations are unknown A computer can think and solve problems by itself. A computer usually solves problems by doing some mathematical and decision- making operations. Computers donot usually make mistakes unless they break down. BASIC was developed to help students All high- level programs must be translated to machine code before the computer can execute them. An operating system program controls input and output operations. Different high- level languages suit different problems. The most important part of problem solving is defining the problem clearly. A computer is very intelligent. It is capable of thinking. An algorithm is a sequence of instructions used to solve a problem The computer is a great help to people because it solves their problems. All problems are equally difficult to solve. III. TRANSLATE THESE SENTENCES INTO VIETNAMES A standard computer system consists of three main sections: the central processing unit (CPU), the main memory and the peripherals. The function of CPU is to execute program instructions and coordinate the activities of all other units. it is the “brain” of the computer. 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. Information is processed and stored in computers as electrical signals. A computer contains thousands of electronic circuits connected by switches. 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. 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. 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. Information stored on magnetic disk can retrieved faster than if that same information were on tape. A program written in one of the high- level languages is called a source program. The extension of internal storage in order to increase the capacity of primary memory is called virtual storage. The surface of a floppy disk is divided into concentric circles or “tracks”, which are then divided into “ sectors”. “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. The total number of pixels in which the display is ivided both horizontally and vertically is known as the resolution. 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. 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 Software is information in the form of data and programs, hardware is the electronic and mechanical parts that make up a computer system 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. According to the writer, The importance of “pixel resolution” decides the quality of image. 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. 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. If you only use word- processing programs, you will need less storage capacity than if you use CAD. Microcomputers make use of two types of main memory: RAM and ROM, both contained in electronic chips connected to the mainboard of the computer. RAM is the working area of the computer, that is the basic location where the microprocessor stores the required information. 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 advantages of the computer mouse over the keyboard are it is very quick way to move around on a screen The mouse also issues instructions to the computer very quickly Mice are so widely used in graphics applications. 27 . Source programs written in high- level languages have to be changed to machine code before the computer can operate on them. 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. 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. Constructing an algorithm is the basic step in solving a problem. Punched cards are the only way of transferring the program to the computer memory. If the data is not added to the program, the computer cannot perform calculation. An algorithm is a sequence of instructions used to solve a problem. All high- level programs must be translated to machine code before the computer can execute them. Different high- level languages suit different problems. It is a must for a programmer to be helped to understand machine code. A computer is a useless machine if its capabilities and limitations are unknown. A computer usually solves problems by doing some mathematical and decision- making operations Computers do not usually make mistakes unless they break down. A computer is useless without a programmer to tell it what to do. IV/ ANSWER THE QUESTION BELOW What’s computer? How many steps are there in a process? What are they? What’s software?

III/ TRANSLATE THESE SENTENCES INTO VIETNAMES. Một hệ thống máy tính chuẩn bao gồm 3 phần chính: đơn vị xử lí trung tâm, bộ nhớ chính và các thiết bị ngoại vi. Chức năng của CPU là thực hiện các lệnh chương trình và phối hợp các hoạt động của các bộ phận khác. Nó được gọi là bộ não của máy tính. Trung tâm điều hành của máy vi tính là đơn vị xử lí trung tâm hay CPU. Bộ phận này được tạo nên bởi một con chip vi xử lí đơn- một mạch tích hợp cái mà thực hiện các lệnh chương trình và giám sát toàn bộ hoạt động của máy tính Thông tin được xử lí và lưu trữ trong máy tính là các tín hiệu điện. Một máy tính bao gồm hàng ngàn mạch điện được nối với nhau bởi các công tắc. Những số 1 và những số 0 tạo thành một nhóm 8 mã số thì đại diện cho một ký tự ( là các chữ cái, con số, biểu tượng). 8 bit hợp lại thì được gọi là 1 byte. Để tránh con số quá lớn và tổng các phép tính của byte . Chúng ta sử dụng các đơn vị như kilobyte, megabytes and gigabytes. Một kilobyte thì bằng 1024 byte, một megabyte bằng 1024 kilobyte, một gigabyte bằng 1024 megabyte. Chúng ta sử dụng các đơn vị như KB, MB, GB để đo bộ nhớ Ram, dun g lượng lưu trữ của đĩa và kích cỡ của các ứng dụng Ram(bộ nhớ truy cập ngẫu nhiên) là tạm thời nghĩa là thông tin bị mất khi máy tính bị tắt, tuy nhiên Rom ( bộ nhớ chỉ đọc) thì cố định và chứa các lệnh cần thiết cho quá trình xử lí. Dung lượng của Ram rất quan trọng nếu chúng ta muốn tăng sự thực hiện của máy tính khi một vài ứng dụng mở ra cùng một thời điểm hay khi tài lệu phức
