PARTS OF A COMPUTER! • There are different parts of a computer which fall under two large categories:
1.HARDWARE2.SOFTWARE
PARTS OF A COMPUTER• HARDWARE: is the physical parts of a
computer , they are also called peripheral devices.
• 4 categories:1.INPUT2.OUTPUT3.PROCESSING4.STORAGE
HARDWARE 1. INPUT:INPUT: any piece of hardware equipment that is used to provide data and used to give your computer directions.
2. PROCCESSING:2. PROCCESSING: any piece of hardware equipment that is used to process the information that is being received from an input device

The History of the Computer
PARTS OF A COMPUTER
SOFTWARE
• is the non physical components of a computer which perform very specific tasks.
THE “INS” of a Computer• Networked Environment• Operating systems• Common Interface
NETWORKING• A computer network is a collection of hardware components and computers connected by communication channels that allow resources and information to be shared.
• At least one computer is able to send/receive data to/from at lease one other computer.
Different types of Networks:
• LAN: local area network-when computers are located close together-same building.
• WAN: wide area network-when computers are further apart and are connected by telephone lines-same area but different buildings.
• CAN: campus area networks-when computers are within a limited area-a school campus.
• HAN: home area network-when computers are contained within a persons home.

OPERATING SYSTEMS• An operating system is a program that runs other
programs which enable the computer’s hardware to communicate with the computer and which enables software to run.
• Operating systems are found on almost any device that contains a computer, including cell phones.
OPERATING SYSTEMS• 4 Different types of Operating systems:
1. Multi-user: allows multiple people to run the same program at the same time.
2. Multi-processing: allows a program to run on more than one central processing unit.
3. Multi-tasking: allows more than one program to run at a time.
4.Multi-threading: allows different parts of one program to run at the same time.
Common Operating Systems
• Windows
• MAC OS
• LINUX
INTERFACE• Interface is how an application’s or programs
graphic or textual controls are laid out and how they respond to user activity.
• On the desktop of your computer what do you see? And what do they mean and do?
• In a chart you will be required to find the definitions of different items that are on your desktop and explain their significance to a computer workstation.
