Lesson Notes By Weeks and Term - Primary 5

WEEK 10&11

SUBJECT: INFORMATION COMMUNICATION TECHNOLOGY

TERM: 1^ST TERM

CLASS: PRIMARY 5

TOPIC: MINI AND MACRO COMPUTER

BEHAVIORAL OBJECTIVES: At the end of the lesson, pupils should be able to: 

1. Describe mini and micro computer
2. Mention the uses of mini and micro computer.

MINI COMPUTER

SIZE: They are small/medium size both in size and performance

SPEED: It does the same work as super computer and mainframe computer at a lower speed. It is also a multiprocessing system and it can support 4-200 user simultaneously.

USAGE; They are used as network servers and internet servers with the help of multiple terminal. They are used in universities, polytechnics, and organizations like banks, internet service companies. Minicomputers are easier to use.

MICRO COMPUTER

SIZE: They are the smallest and least expensive of all computers.

SPEED: They possess the smallest memory and less power. These computer permit only fewer peripherals to be attached as they are relatively smaller in size.

USAGE: They are known as personal computer or pc. Examples are desktop computer, laptop computer, palmtop, tablets, etc

EVALUATION

Explain mini and micro computer  based on its size, sped and usage.

Super Computers

They are most powerful and expensive computers. they have externally large storage capacities and processing speed is at least 10 times faster than other computers. Some of the super computers are NEC , CRAY ,CYBER 205,CDC STAR 100 etc. Supercomputers are the most powerful and expensive computers. They process billions of instructions in one second. They are also the largest type of computers.

Supercomputers are used in big organisations

like the military, airports and other scientific organisations.

Main-frame

They are medium or large machine, made of several units connected together .

It’s generally used in big organizations.

Minicomputers

They are like small mainframes. They consist of a few separate units connected together. They are not powerful as mainframe computers.

Micro-computer

They are the smallest general purpose computers. They are about the same size an of a typewriter machine. They are used in different applications like business, engineering, schools, colleges, entertainment etc.
