V. Translate the text

IMB (international business Machines) launched the PC in 1981. Improved versions quickly followed. The basic PC had just 64K (K=Kilobyte) of RAM. RAM is (R)andom (A)ccess (M)emory, the computer's built-it memory, used for holding the instruction programs, for working space, and working storage. The first PC had one floppy-disk drive. Floppy disks are a mean of electronically recording computer programs and computer output.

The disks are “read” and “written to” in a disk drive. They are called “floppy” disks because, initially, they were.

Today, huge-capacity storage disks are built into most computers.

Unit 4

What is hardware?

The hardware- the devices composing a computer system.

Computer hardware can be divided into four categories:

  • input hardware.
  • processing hardware.
  • storage hardware.
  • output hardware.

Input hardware

Input hardware collects data and converts them into a form suitable for computer processing. The most common input device is a keyboard. It looks very much like a typewriter. The mouse is hand-held device connected to the computer by a small cable. As the mouse is rolled across the desktop, the cursor moves across the screen. When the cursor reaches the desired location, the user usually pushes a button on the mouse once or twice to give a command to the computer.

Processing hardware

 

Processing hardware directs the execution of software instructions in the computer. The most common components of processing hardware are the central processing unit and main memory.

The central processing unit (CPU) is the brain of the computer. It reads and interprets software instructions and coordinates the processing.

Memory is the component of the computer in which information is stored. There are two types of computer memory: RAM and ROM.

RAM (random access memory) is the memory, used for creating, loading and running programs.

ROM (read only memory) is computer memory used to hold programmed instructions to the system.

The more memory you have in your computer, the more operations you can perform.

Storage hardware

The purpose of storage hardware is to store computer instructions and date hardware.

There are two types of output; soft copy and hard copy. Soft copy is information that is seen on a television-like screen, of monitor, attached to most computers. It is temporary; as soon as the monitor is turned off or new information is required, the old information vanishes. Hard copy is output printed in a tangible form such as on paper. It can be read without using the computer and can be conveniently carried around, written on, or passed to other readers.

Vocabulary:

 

Keyboard клавиатура

Mouse мышь
