This is the process of producing results from the data for getting useful information. What is the use of epabx? Thereby it coordinates the activities of computer’s peripheral equipment as they perform the input and output.

Merge this question into. Again the output is also stored inside the computer for further processing. If we have two telephone line it can be divided into eight lines and the incoming and outgoing calls … can be done from epsbx eight no. The matrix checks for which port the no. After you enter data through the input device it is stored in the siagram storage unit.

EPABX systm used for the internally incoming and outgoing of telephonic calls. This is the process of entering data and programs in to the computer system.

Too much for this forum. The call is established and held as long as you diagrram the receiver off hook. It also acts as a switch board operator when several users access the computer simultaneously. Would you like to merge this question into it? Data is transferred to ALU from storage unit when required.


Block diagram of a computer with explanation? The general term “Extension” is used to refer to any end point on the branch. The computer system is divided into three separate units for its operation.

The third part maintains the normal functioning of the EPABX including power supply, configuration, troubleshooting and generation of various reports. You should know that computer is an electronic machine like any other machine which takes as inputs raw data and performs some processing giving out processed data. boock

External Telephone Connection 4. WikiAnswers does not support graphic images.

Therefore, the input unit takes data from us to the computer in an organized manner for processing. It provides space for storing data and instructions. We discuss below each of these Computer operations 1. After processing the output is returned back to storage unit for further processing or getting stored. Controlling of all operations like input, processing and output are performed by control unit.

It converts the signalling as well the voice into digital and handovers to the matrix.

The task of performing operations like arithmetic and logical operations is called processing. They can solve highly complicated problems quickly and accurately. What is meaning of systme You may call CPU as the brain of any computer system. It is then sent back to the storage unit.

A telephone exchange serving a single organization, having a switchboard and associated equipment, usually located on the customer’s premises; provides for switching calls bet … ween any two extensions served by the exchange or between any extension and the national telephone system via a trunk to a central office.


They are essentially crosspoint switches with touch-tone decoders. The Central Processing Unit CPU takes data and instructions from the storage epabxx and makes all sorts of calculations based on the instructions given and the type of data provided. A computer as shown in Fig. But I diagrxm try to explain atleast the basic fundamentals. Control Unit is responsible for co ordinating various operations using time signal. Data has to be fed into the system epabz the actual processing starts.

Blok like processing of programs stored in the main memory, interpretation of the instructions and issuing of signals for other units of the computer to execute them. Similarly the output produced by the computer after processing must also be kept somewhere inside the computer before being given to you in human readable form.

It takes bllck of step by step processing of all operations inside the computer. Choose a video to embed. Split and merge into it. The manner how instructions are executed and the above operations are performed. Please see the related link below for an image of the block diagram of the DX2. Hope you got some idea. The storage unit performs the following major functions: Block diagram of diwgram communication? Block diagram of optical mouse?

Block diagram of CDMA? Look for a night course on telephone technology. They are 1 arithmetic logical unit 2 control unit. Block diagram of microprocessor?
