Number system and it's types 1. Decimal number system:- A system based on decimal digits (0,1,2,3,4,5,6,7,8,9).Decimal system have radix or base 10 which means that each digit in the number is multiplied by 10 raised to power corresponding to that digit position. Example:- 86=8x10+6x1 2. Binary number system:- It has two symbols or possible digit … Continue reading Number system and it’s type

# Computer architecture

# Sequential Circuits

Sequential Circuits These are logic circuits whose present output depends on past inputs.It stores and remember information.It is time dependent.It is a connection of flip flops and gates.Two types are- ¤Synchronous-It uses flip flops and its status can change only at discrete instants. ¤Asynchronous-It can be regarded as combinational circuits with feedback path.

# Combinational Circuits

Combinational Circuits These are interconnected circuits of gates according to certain value to produce an output depending on its value.It should not have feedback loops.It can be represented as a network of gates.It can be expressed by a truth table or a Boolean expression.It is independent of time.
