Computers are thought to have many remarkable powers. 1_________________________________. First, computers have circuits for performing arithmetic operations, such as addition, subtraction, division, multiplication and exponentiation. 2___________________________________. After all, if we couldn’t feed information in and get results back, these machines wouldn't be of much use. However, certain computers for example minicomputers and microcomputers are used to control directly things such as robots, aircraft navigation systems, medical instruments, etc.
3_________________________________. Computer can solve a series of problems and make hundreds, even thousands, of logical decisions without becoming tired or bored. 4_________________________________. A computer can replace people in dull, routine tasks, but it has no originality; it works according to the instructions given to it. A computer cannot do anything unless a person tells it what to do and gives it the appropriate information.

  • Third, computers have circuits which can make decisions.
  • Second, computers have a means of communicating with the user.
  • However, most computers whether large or small, have three basic capabilities.
  • It can find the solution to a problem in a fraction of the time it takes a human being to do the job.

The basic job of computers is the processing of information. For this reason, computers can be defined as devices which accept information in the form of instructions called a program and characters called data, perform mathematical and/or logical operations on the information, and then supply results of these operations. The program, or part of it, which tells the computers what to do and the data, which provide the information needed to solve the problem, are kept inside the computer in a place called memory.

1_______. Based on capacity, speed and reliability they can be divided into three categories of computers:
1. The mainframe computers are computers used by large organizations like meteorological surveys and statistical institutes for performing bulk mathematical computations. 2_______.
2. The microcomputers are the most frequently used computers better known by the name of “personal computers”. 3_______.
3. The minicomputers like the mainframe computers are used by business organization. 4_______.
Computers are categorized on the basis of physical structures and the purpose of their use
The mainframe computers are core computers which are used for desktop functions of over one hundred people simultaneously
Microcomputer is the type of computer meant for public use
The difference being that minicomputer can support the simultaneous working of up to 100 users and is usually maintained in business organizations for the maintenance of accounts and finances

One of the most important characteristics of a computer is its capability of storing information in its memory long enough to process it. 1__________________________________.
The memory of the first computers was made up of a kind of grid of fine vertical and horizontal wires. At each intersection where the wires crossed there was a small ferrite ring called a core and therefore we use the name “core memory”. 2__________________________________. There is one problem, however, with semiconductor memory: when power is removed, information in the memory is lost, unlike core memory which is capable of retaining information during a power failure.
3__________________________________. A magnetic bubble memory can store information at a greater density than existing memories, which makes it very suitable. 4__________________________________.
Not all computers have the same type of memory.
With the development of integrated circuits semiconductor memories (or chips) came into use.
Another development in the field of computer memories is bubble memory.
Microbubble memories are not expensive, consume little power, are small in size, and are highly reliable.

A computer system is a collection of components that work together to process data. The purpose of a computer system is to make it as easy as possible for you to use a computer to solve problems. 1___________________________________. The hardware elements are the mechanical devices in the system, the machinery and the electronics that perform physical functions. 2___________________________________. Documentation includes the manuals and listings that tell you how to use the hardware and software.
3__________________________________. Usually, a computer system requires three basic hardware items: the computer, which performs all data processing; a terminal device, used like a typewriter for two-way communication between the user and the system; and a storage medium for storing programs and data. 4__________________________________.
A functioning computer system combines hardware elements with software elements.
The software elements are the programs written for the system; these programs perform logical and mathematical operations and provide a means for you to control the system.
Collectively these components provide a complete computer system: system hardware + system software + system documentation = computer system.
These three devices - the computer, the terminal and the storage medium - are the required hardware components of any computer system.

Peripheral devices are categorized as input/output (I/O) devices since the functions they perform provide information (input) to the computer, accept information (output) from the computer, or do both. 1__________________________________. Terminals and storage devices are input/output devices because they perform both input and output operations.
2_________________________________. These programs include operations, functions, and routines that make it easier for you to use the hardware to solve problems and produce results. 3___________________________________. Others perform difficult or lengthy mathematical calculations. 4_____________________________________.
Line printers are output devices because they perform only output operations.
System software is an organized set of supplied programs that effectively transform the system hardware components into usable tools.
For example, some system programs store and retrieve data among the various peripheral devices.
Some programs allow you to create, edit, and process application programs of your own.

A disk is a data storage medium consisting of a flat, circular, magnetic surface on which information can be recorded. 1_________________________________. These already contain information and programs, and are ready to use.
2______________________________. But these disks must be formatted before they can be used.
3______________________________. This means you can read from but not write to the disk, making it impossible to write accidentally over information. 4_______________________________.
You will receive several disks with your computer.
Blank disks can be used to store your own information and programs.
Disks which contain important information can be write-protected.
Your disks can be write-protected - instructions are included in each box of disks.
