What is an adder

posted on , by Mahesh

Adder An adder is a kind of calculator that is used to add two binary numbers. When I say, calculator, I don’t mean one with buttons, this one is a circuit that can be integrated with many other circuits for a wide range of applications. There are two kinds of adders; Half adder Full adder Half Adder With the help of half adder, we can design circuits that are capable of performing ...

What is parity bit?

posted on , by Mahesh

Parity bits are used as a form of error checking during the transmission of information. When old modem is transmitted data over a network or communications device, the data was encoded into a series of ones and zeros called bits (modern modems send information in packets and check for errors in different ways, so a parity bit is unnecessary). A single bit can describe only two possible states, 0 (off) or 1 (on). Several bits are thus needed to describe a letter or number. ...

What is opcode and operand?

posted on , by Mahesh

Opcode is an instruction that tells processor what to do with the variable or data written besides it. Oprand is a variable that stores data(and data can be a memory address or any data that we want to process). e.g. MVI A,B here instruction MVI is an opcode. A & B are oprands. Same for other instruction ...

Write an algorithm, draw a flow chart and write its corresponding C program to convert a decimal number to its equivalent hexadecimal number.

posted on , by Mahesh

An algorithm is a finite set of steps defining the solution of a particular problem. An algorithm is expressed in pseudo code – something resembling C language or Pascal, but with some statements in English rather than within the programming language A sequential solution of any program that written in human language, called algorithm. Algorithm is first step of the solution ...
