Data traffic moves: simplex, half-duplex, and full-duplex.

Answer:

There are three ways, or modes, for transmitting data from one point to another. The names are shown down__

1. Simplex.

2. Half Duplex.

3. Full Duplex.

Simplex mode: If transmission mode is simplex, communication can take place in only direction. Devices connected to such a circuit are either a sender or only a receiver.

Half Duplex mode:A Half Duplex system can transmit data in directions, but only in one direction at a time. Thus a half duplex line can alternately send and receive data. It requires two wires.

Full Duplex: A full duplex is use that allows information to flow simultaneously in both directions on the transmission path.

Draw the basic organization of computer

Answer: The basic organization of computer__ Input Unit: · It accepts (or reads) instructions and data from outside. · It converts these instructions and data in computer acceptable form · It supplies the converted instructions and data to the computer system for further processing. Central Processing Unit (CPU): Control Unit: Control unit of a computer system manages and coordinates the operations of all other components of the computer system. Arithmetic Logic Unit(ALU): Arithmetic logic unit of a computer system is the place, where the actual executions of instruction, takes place during processing operation. Storage Unit: Primary Memory: It is volatile ( loses data on power dissipation). It is used to hold running program instruction, data, intermediate results, and results of ongoing processing of jobs. Secondary Memory: It i

Describe the four basic data types. How could we extend the range of values they represent?

Answer: The basic four data types are: Data Type Integer Type Character Type Floating Point Type Void Type signed int short int long int unsigned unsigned int unsigned short int unsigned long int char signed char unsigned char float double long double

What are ASCII, BCD, EBCDIC, Unicode and parity bit?

ASCII: ASCII is the American Standard Code for Information Interchange. The characters encoded are number 0-9, a-z, A-Z, basic punctuation symbols, control codes.
