PARTS OF A COMPUTER! There are different parts of a computer which fall under two large categories: HARDWARE SOFTWARE
7
PARTS OF A COMPUTER HARDWARE: is the physical parts of a computer , they are also called peripheral devices. 4 categories: INPUT OUTPUT PROCESSING STORAGE

HARDWARE 1. INPUT: any piece of hardware equipment that is used to provide data and used to give your computer directions. 2. PROCCESSING: any piece of hardware equipment that is used to process the information that is being received from an input device 3. OUTPUT: any piece of hardware equipment that is used to give data from a computer after it has been processed. 4. STORAGE: piece of hardware which saves information so it can be recalled later.

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.
14
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.
17
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. Multi-threading: allows different parts of one program to run at the same time.

Common Operating Systems
Windows MAC OS LINUX
