Differences between positional and non-positional number system?

Answer:

Positional Number System:

In positional number system, there are only a few symbols called digits, and these symbols represent different values depending on the position they occupy in the number. The value of each digit in such a number is determined by three considerations__

1. The digit.

2. The position of the digit in the number.

3. The base of the number system.

Non-Positional Number System:

In the non-positional number systems, the characters used are I for 1, II for 2, etc, and are of position invariant, i.e. each symbol represents the same value regardless of its position in the number. Since it is very difficult to perform arithmetic calculations with such a number system, positional number system were developed.

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
