MODULE 1 - Introduction to Computer System Flashcards
Computer
is an Electronic device that can be programmed to accept data (input), process it and generate result (output)
Computer System
Computer along with additional hardware and software
Data
Raw and unorganized facts that are processed to get meaningful information
Information
Combination of raw and unorganized facts that been processed
Features of Computer System
Programmable, accepts raw data and produces information and a Digital machine
Characteristics of Computer System -Automatic
The computer once programmed to perform some tasks can continue without any human intervention
Characteristics of Computer System -Speed
With the latest microprocessor it gives the computer a huge processing power that used for performing complex operations with very high operating speed
Characteristics of Computer System -Accuracy
The accuracy depends on the program instructions and the input data. The computer will produce wrong result if there any mistakes in program instruction, referred as Garbage In Garbage Out(GIGO)
Characteristics of Computer System -Versatile
It is now an essential part of every industry, profession and different field.
Characteristics of Computer System -Reliable
Perform multiples tasks without any mistake with the lightning speed.
Characteristics of Computer System - Diligent
Can work day and night without any breaks
Characteristics of Computer System - Memory
To store data and program instruction
Characteristics of Computer System - Programmable
The computer need a set of instruction called a program to perform any task on its own
