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…

DIVISIONAL FACTS OF OPERATING SYSTEM

OPERATING SYSTEMS DIVISIONAL FACTS

An operating system is a software program that acts as an interface between the user and the hardware of the computer.  It also manages the components of the machine such as processor management, disk resource management, input output files, devices etc.

Some of the operating system i am going to show you.  So lets get started User interface :  the user interface allow the user to interact with the machine.  There are two types of user interface given by the user interface developers.  They are as follows 1.Character line user interface such as linux redhat 2.Graphical line user interface such as windows operating system In character line user interface the user have to interact with the computer by giving commands that’s why it is also called as command line interface.

In graphical user interface this control is given to the user where the user with mouse or keyboard will control the command or an object kept on the desktop of the computer.  For exa…

HARDWARE COMPONENTS OF COMPUTER A LITTLE SUMMARY

HARDWARE COMPONENTS- INPUT AND OUTPUT COMPONENTS In this topic we discuss the major hardware components of a microcomputer system, which are used for input, output, processing, storage, electrical supply and communication.
Most input and output devices are outside the computer case.Most processing and storage components are contained inside the case.The most important component in the case is the central processing unit (CPU) is called the processor and microprocessor.
As its name implies, the device is central to all processing done by the computer.Data received by input devices is read by the cpu , and output from the cpu is written to output devices.The cpu writes data and instruction in storage devices and performs calculation and other data processing.
Whether inside or outside the case and regardless of the function the device performs,each hardware input, output, or storage device require these elements to operate:
A method for the CPU to communicate with the device
·The device send…
