Serial port and parallel port are used for transferring data in/out of the computer. In serial port transmission only 1 bit is transmitted at a time. Most serial ports on personal computers conform to the RS-232C or RS-422 standards. A parallel interface for connecting an external device such as a printer. On PCs, the parallel port uses a 25-pin connector (type DB-25. and is used to connect printers, computers and other devices that need relatively high bandwidth. It uses parallel transmission of data.

These are the communication channel that enables your computer to exchange information with various devices.

The most important electronic component on the computer. It is a programmable logical device for processing data. In the world of personal computers, the terms MICROPROCESSOR and CPU are used interchangeably.

In a hierarchical structure there is a grouping of things into levels. There is a “top” level and then a series of lower levels under it. It’s all about abstraction. At each level you describe a concept with enough detail for you to have a good feel for what lies below it. Here’s a snipet from Brian Harvey’s course notes, Reading Material for: CS 61A, for his first class.

Computer is a programmable machine. It the integral part of everyday life.
