Program Plan Intro

Computer system:

• A computer system is a combination of various input and output devices such as, motherboard, hard drive, rams, CPU, etc which enables the system to perform various operations.
•  The basic objective of computer system is to enable their users to perform multiple tasks at the same time, which can be done by using motherboard.
• In the computer system, the user can decide what function to perform on the system for the specific period. Basically, the computer system is also known as general-purpose programmable system.
• A computer system installs and stores the operating system in order to make a system work.

Example: A user is working on PC to perform some specific task and at the same time he wants to open some other file or document, so the motherboard of a computer system assists the user to perform other task at the same time.

Embedded system:

• This system also performs the same operations as computer systems does, but the main difference is that it performs only one or some set of operations for the specific period of time.
• In other words, the embedded system is dedicated to single purpose or a small set of purposes.

Examples: An ATM machine, air condition, refrigerator, home appliances and many electronic devices.

An embedded system uses chip to install the operating system within the system in order to make a system work.
