CODES OF LANGUAGE IN COMPUTER SYSTEM. WHAT ARE THE OTHER CODES WHICH ARE USED IN COMPUTER SYSTEM?

CODES OF LANGUAGE IN COMPUTER SYSTEM.WHAT ARE THE OTHER CODES WHICH ARE USED IN COMPUTER SYSTEM?There are many codes in computer system which may remain unnoticed by many computer geeks and nerds.I also first didn’t see it but I am going to share it because these are important codes and used by many computer hardware developers, vendors and computer software developers. They are mostly understood by ELECTRONICS AND ELECTRICAL ENGINEERING geeks or nerds.They are as under :·ERROR DETECTION CODES
·ALPHANUMERIC CODES·REFTLECTED CODESFirst we will discuss something about ERROR DETECTION CODES.ERROR DETECTION CODES:Binary information , be it pulse modulated signals or digital computer input or output, may be transmitted though some form of communication medium or electrical wires or radio waves.Any external noise introduced into physical communication medium or electric wires changes bit values from 0 to 1 or vice versa.An error detection code can be used to detect errors during transmission…

ALL ABOUT LASER PRINTER

ALL ABOUT LASER PRINTER

This printer is also known as page printer because they receive their print job one page at a type.There are two major types of laser printer 1)The first use a laser to scan the image on two a organic photo conductive drum (OPC) 2)The second use an array of led to create the image on the drum.Xerox invented this printer in 1971 but the first laser printer was introduced y hp in 1984.
BASIC COMPONENTS
Tonner cartridge:Tonner is a black carbon substance mixed with polyster resin to make it flow better and iron oxide particles to make it sensitive to electrical charge.Tonner contain a medium called developer which carries the tonner until it is used by the EP(Electro photography) process.
The tonner also contains the opc drum. The drum is coated with a photo sensitive material that hold a static charge unless it is exposed to light.The drum also contains a cleaning blade known as doctor blade. That continuously scraps the unused tonner from the drum.

IS DIGITAL COMPUTERS ARE VALUABLE?

DIGITAL COMPUTERS
Today computers are used extensively in every day life.  It is used in basic as well as industrial, scientific and commercial purposes.  Our space program would not have been well developed without the real time monitoring of the machine of the spacecraft which was going to land on moon or any other planet of the scheduled program or launching of satellites on the orbit of earth. This is the scientific purpose i told you about while it has commercial purposes.  Like automatic data processing which the business enterprise uses.
It has many works in educational purposes for example multiple choice question answers can be checked without any error and then the results can be printed out automatically with the help of the printer which is connected to the digital computer.
  Digital computer are also used in air traffic control to control the aviation industry to help them control the planes by sending them data about the distance between the planes and the ground as well a…

SUBTRACTION IN COMPUTERS

SUBTRACTION IN COMPUTERS

HOW DO COMPUTERS SUBTRACT IN ANY EQUATION?

Computer is one of the best inventions in the whole world. Now in the era of electronics, computers are shrinking in the size.The dream of having pocket computers which was shown in many Hollywood as well as many film industry is now a reality.
 Many unimaginable discoveries and inventions are done with the help of computers. As in this age theof semiconductors and embedded systems we are achieving what was a dream, about 60-70 years ago.
Now to achieve such a dream, the hard-work and dedication needed was given by many scientists whose aim was to uplift the society.Now if we want to invent something we need good hold on arithmetic computation.This computation was understood and logically implemented by many scientists and engineers.
We use Complements in digital computers for almost simplifying the subtraction operation and for logical manipulations and computations.
There are two types of complement for each base-r system…
