There are two basic formats or types of optical disks. Optical disks Use laser technology and have the greatest capacity. called as floppy disk because data is stored on a very thin flexible or floppy plastic disk Hard disks are typically used to store programs and very large data files Have a much greater capacity and are able to access information much faster than floppy disks.

This type of memory stores the information on storage media such as floppy disks and CDs Floppy disks ( also known as diskettes) widely used to store and transport data from one computer to another. It stores data and programs for future use. It is sometimes referred to as temporary storage It is located in the system unit on tiny memory chips.Д§ Secondary Storage It also holds data and programs permanently. It holds the processed information before it s output. Main memory (internal storage) Holds data and program instructions for processing the data. That is, two pieces of data are compared to see whether one is equal to (=), less than () the other.Д¦ Memory ( Primary Storage or Random Access Memory) Logical operations consist of comparisons. it directs the movement of electronic signals between memory and the arithmetic logic unit it also directs these control signals between the CPU and input and output devices Arithmetic-Logic Unit usually called the ALU, performs two types of operations вЂ“ arithmetic and logical Arithmetic operations are the fundamental math operations: addition, subtraction, multiplication and division.

It has two components: the control unit and arithmetic-logic unitДҐ Control Unit: tells the rest of the computer system how to carry out a programвЂ™s instructions. The central processor performs calculations, compares data and produces results. It also thinks for the computer with the help of the human using it. It is like the brain of the computer which controls the whole computer. A microcomputers CPU is contained on a single integrated circuit or microprocessor chip. Is the electronic circuitry housed within the computer cabinet The two of the most important components of the system unit are: Central processing Unit (CPU) Controls and manipulates data to produce information.

Has one or more buttons for selecting commands Also used for drawing figures.Д¤ SYSTEM UNIT Central processing Unit (CPU) It directs the insertion point or cursor on the display screen. Mouse Is a pointing device that typically rolls on the desktop. Keyboard Looks like a typewriter keyboard, but has additional specialized keys. Translate data and programs that humans can understand into a form that the computer can process. It refers to the tangible devices that can be seen, touched and felt The hardware that makes up the most basic computer system includes the monitor, keyboard and a system unit Physical components fall into five categories: Input devices System unit Secondary storage Output devices Communication devicesДЈ INPUT DEVICES Mouse Keyboard FIVE CATEGORIES OF HARDWARE: 1 ELEMENTS OF A COMPUTER SYSTEM HARDWARE SOFTWARE PEOPLEWARE DATAДў HARDWARE: The physical components of a computer system
