COMPUTER INTRODUCTION

COMPUTER INTRODUCTION

Hello friends!!!. meet again with me on Sharing Together, this time we will discuss about the introduction of computer. Yes maybe some friends wonder, why the material back again ?. I deliberately made the material to the beginning because this is the basics of computer learning, then we have to review again.
Okay friends all of us just see the introduction of the following computer.

COMPUTER DEFINITION

 

The first discussion We start with the understanding of the computer first, the Computer is a tool used to process data according to procedures that have been formulated. The word computer was originally used to describe people whose work performed arithmetic calculations or that we used to know with calculations, with or without tools, but the meaning of the word was then transferred to the machine itself. Originally, information processing was almost all related to arithmetic problems, but today's computers are used for many tasks unrelated to mathematics.
The word computer in general has been used to define people performing arithmetic calculations, with or without auxiliary machines. According to the Barnhart Concise Dictionary of Etymology, the word was used in English in 1646 as the word for "one who counts" then before 1897 is also used as a "mechanical counting device". During World War II the word refers to US and British female workers whose work calculates the artillery path of war with a calculating machine.
The man who designed one of the first calculators (the analytical engine) was Charles Babbage. In addition, various simple machine tools such as slide rule can also be regarded as a computer. So the brief understanding of computers can be summarized as follows.

What is a Computer?

A computeris electronic device, operates under the control of instructions stored in its own memory, which can receive data, process data according to certain rules, produce results, and store results for future use.

Data and Information

Computers process data into information. Datalis collection of unprocessed items, which can include text, numbers, images, audio, and video. Information conveys meaning and is useful to people.

Processing of Cycle Information

Computers process data (input) to information (output). Computers implement the process using the instructions, which is a step that tells the computer how to do their par-specific task. A collection of related instructions is organized for the same purpose referred to as software. A computer often stores data, information, and instructions in storage for future use. Some people refer to a series of inputs, processes, outputs, and storage activities as a processing information cycle. Most computers today communicate with other computers. As a result, communication has also become an important element of
processing cycle information.

Components of a Computer

A computer contains many electrical, electronic, and mechanical components known as hardware. These components include input devices, device outputs, system units, storage devices, and device com- munications.

Input Device

hardware component input device that allows you to enter data and instructions
into the computer. Five widely used input devices are keyboard, mouse, microphone, scanner,
and Web cam. A computer keyboard contains your key presses to enter data to the computer. for security purposes, some keyboards include fingerprint reader, which allows you to work with puter com-only if your fingerprint is recognized. A mouse is a small handheld device. with the mouse, you control the movement of small symbols on the screen, called pointers, and you make a selection from the screen. A microphone lets you talk to a computer. A scanner converts rial-printed pairs (such as text and images) into a usable computer form. A Web cam is a digital video camera that allows you to make movies or take pictures and store them on a computer rather than on a recording or a movie

Output Devices

hardware output device A component that delivers information to one or more persons. Three commonly used printer output devices, monitors, and speakers The printer produces text and images on a media-like physical paper. A monitor displays text, graphics, and video on the screen. Speakers allow you to hear music, sound, and other audio (sound).

Unit system

System Units are cases that contain electronics computer components used to process data Circuits from system units are usually part of or connected to a circuit board called
motherboard. The two main components on the motherboard are the processor and memory. The processor, also called aCPU (central processing unit), is an electronic component that interprets and executes basic instructions that operate the computer. Memoryconsists are electronic components that store instructions waiting for to be executed and data required by their instructions. Although some forms of permanent memory, most memory stores data and temporary instructions, which means the contents are erased when the computer is turned off.

storage device

is a storage device, for example: hard drive, flash, cd, dvd, floppy, etc ..

Device communication

A hardware component communication device that enables computers to transmit and receive data, instructions, and information to and from one or more comput-ers or mobile devices. A widely used communication-cation device is a modem. Communication occurs via cable, telephone line, cellular radio network, satellite, and
other transmission medium. Some media transmissions, such as satellite and cellular radio net works, are wireless, meaning they have no physical lines or wires.
So many computer recognition from me, may be useful for all of us.
if any writing is wrong please understand, his name is also still learning.
That is all and thank you
