ARTICLES ABOUT computer technology

Computers are tools used to process the data according to the procedures that have been formulated. Computer word originally used to describe people who perkerjaannya perform arithmetic calculations, with or without hearing aids, but the meaning of the word is then transferred to the machine itself. Origins, processing information almost exclusively related to arithmetical problems, but modern computers are used for many tasks unrelated to mathematics.


In the sense that there are tools such as slide rules, mechanical calculators types ranging from abacus and so on, until all the contemporary electronic computers. The term better suited to a broad sense such as "computer" is "that process information" or "information processing systems." Over the years there have been several different meanings in the word "computer", and several different words are now called called a computer.
Said computer once commonly used to define people who perform arithmetic calculations, with or without auxiliary engine, According to Barnhart Concise Dictionary of Etymology, the word is used in English in 1646 as the word for "people who count" and then before 1897 is also used as a "mechanical calculators". During World War II, the word refers to the workers of the United States and British women who work calculate artillery street war with the machine count.
Charles Babbage designed one of the first calculating machine called the analytical engine. In addition, a variety of simple mechanical devices such as slide rule also has to be said as a computer.

1. Computer is the result of sophisticated industrial useful.

Computers as we know it today is the result of the development of electronics and informatics technology so that its original shape sized computer and eating places, now are small with great ability. Industrial progress of electronic components IC (integrated circuit) has encouraged the creation of a variety of diverse devices IC chip and supports a variety of purposes manufacture of electronic products. Electronics technology advancement is inseparable from the advancement of knowledge and the processing of semiconductor materials, especially silicon.

The benefits of today's computers are quite varied began as a tool to write, draw, edit photos, play video, play songs until the analysis of the research data as well as to operate the programs completion of the problems of scientific, industrial and deploying. The world's children have long been familiar with the tools of game play that is controlled by a computer system. In industry, the computer has been used to control the production machines with high accuracy (eg CNC, a versatile machine in the metal industry) so that we can find a wide range of metal products industry are varied and we imagine is difficult if done manually. There are many machines in the garment industry is equipped with computer control, for example, the company can produce bodir hat cap with embroidered uniform image quality in large quantities in a short time. In trading companies such as department stores have used a cash register (cash register) equipped with computer control so that the machine can be controlled by the managers only from his room only. In education, in addition to the lessons encountered as a tool, a lot of laboratory equipment that is equipped with a computer so that the device can work more closely and can overcome barriers to human senses. From the field of education and research that use such tools produced a variety of useful research results that do not feel already widely used in everyday life of society. Diverse drugs both for human health and agriculture and livestock have been widely used by the community. In the field of biotechnology, equipment culture has much to be equipped with a precision computer control to seek work in a sterile room. The Australian company has developed a robot for the purposes of this biotechnology. The application of the most sophisticated computer controls contained in aircraft and spacecraft. To be able to overcome the obstacles of nature and difficult for a pilot to manually, a plane can be controlled automatically so that it can fly safely at the destination.

Thus the benefits of the computer, for it is in this paper are introduced on a computer and how to assemble. In this paper not explained carefully how to build an electronic circuit to build a computer or computer software (software), in order to know this you still have lectures in the field of Electronics and Information Technology. This article is meant for you not to know any computer or understand it, you may be familiar with computer parts, assembles them and know how it works, especially to know how to operate the software application then you will feel the benefits of such a large computer. Here again not elaborated on the history of the invention of the computer, you need only believe that computers are industrial products that utilize a variety of research and testing of bebeberapa scientific fields. For example the scientific field of electronics, informatics, management, materials chemistry, materials physics, physical chemistry, electrochemistry and others.
It was some of the computer technology that will be released in 2010, when seen from the shape and sophistication it is the technology that will come in 2010 tabhun really - really quite fantastic. TriBook with three ultra-wide-screen concept is 21? the width of the screen. It also has an 8x SuperDrive, a 1TB hard drive, and MacBook Pro-caliber CPU, plus a trackpad multitouch keyboard,
2. HOW TO WORK COMPUTER
Memory
In this system, memory is a sequence of bytes numbered (such as "cells" or "pigeon holes"), each containing a small piece of information. This information may be a command to tell the computer what to do. Cells may contain data that is necessary for the computer to perform a command. Each slot may contain one, and what is now the data may then be perintah.Memori store various forms of information as binary numbers. Information that is not going to solve a binary form (encoded) with a number of instructions that turn it into a sequence of numbers or figures. For example: The letter F is stored as a decimal number 70 (or binary digits) using one of the methods solving. More complex instructions can be used to store images, sound, video, and various kinds of information. The information can be stored in a sell is called a byte.

Processing

Central Processing Unit or CPU (central processing unit) role is to process the orders given by the computer user, manage shared data on the computer. Processing unit or device will also communicate with the device input, output and storage to carry out instructions that are interrelated.

In the von Neumann architecture of the original, he describes an Arithmetic and Logic Unit and a Control Unit. In modern computers, the unit is located within a single integrated circuit (IC - Integrated Circuit), which is usually called a CPU (Central Processing Unit).
Arithmetic and Logic Unit, or Arithmetic Logic Unit (ALU), is a device that performs basic implementation such as the implementation of arithmetic (addition, subtraction, and the like), execution logic (AND, OR, NOT), and the implementation of the comparison (for example, compare the content as much as two slots for equality). On this unit performed "work" truth.
The control unit saves the current command is performed by a computer, instruct the ALU for implementation and retrieve information (from memory) required to perform it, and move the result back to the appropriate memory location. This unit serves to control the reading of instructions a computer program.
Inputs and results

I / O allows the computer to get information from the outside world, and put his work there, it can be physical (hardcopy) or non-physical (softcopy). There are a wide variety of I / O devices, from the familiar keyboard, monitor and disk drives, to the more unusual such as a webcam (web camera, printer, scanner, and so on.
Which is owned by all the usual input devices is that they encode (convert) the information from a wide into data that can be further processed by a digital computer system. Tool output, decode the data into information which can be understood by the computer user. In this sense, the digital computer system is an example of a data processing system.
Instructions

Commands discussed above is not a command such as human language. Computers only have a simple command in a limited number of well-defined. Regular orders is understood most computers are "copy the contents of cell 123, and a clone in cell 456", "add the contents of cell 666 to cell 042, and place result in cell 013", and "if the contents of cell 999 are 0, the next command you in cell 345 ".
Instructions are represented within the computer as numbers - the code for "copy" might be 001, for example. A set of specific commands are supported by a particular computer is known as machine language. In practice, people do not normally write commands to computers directly in machine language but use the programming language "high level" which is then translated into the machine language automatically by special computer programs (interpreters and compilers). Some programming languages ​​are closely related to the machine language, such as assembler (low level languages); on the other hand, languages ​​like Prolog are based on abstract principles far removed from the details of the actual implementation by the engine (high level language).
3. Parts of a computer

Computer consists of two major parts of software (software) and hardware (hardware).
Hardware

Processor or CPU as a data processing unit
RAM memory, which store data temporarily
Hard drives, semi-permanent storage media
An input device, the media used to input data to be processed by the UPS, such as a mouse, keyboard, and tablet
The output device, the media used to display the output of the CPU processing, such as monitors, speakers, plotter, projectors and printers
Software

Operating system
Basic program on a computer that connects users with computer hardware. The operating system used is Linux, Windows, and Mac OS. The task of operating systems including (but not only) regulates the execution of programs on it, the coordination of input, output, processing, memory, and software installation.
Computer program
An additional application that is installed in accordance with its operating system
Slots on the computer

ISA / PCI slot for the card input additional non-graphic
AGP / PCIe slot for graphics add-in card input
IDE / SCSI / SATA, slots for hard drives / ODD
USB, media input slots for plug-and-play (plug and play, which means that devices can be connected directly to a computer and can be used).
4. TYPES OF COMPUTER
Analog computer is a term used to describe a computing tool that works on the level of analog. Level analogue here is the opponent (dual) of the digital level, digital level which is a voltage level 'high' (high) and 'low' (lower), which are used in the implementation of binary numbers. Basically, the electronic components that are used as the core of an analog computer is the op-amp (operational amplifier).
digitalAdalah computer computer machine created to process quantitative data in the form of numbers, letters, punctuation and others. Which pemrosesnya implemented based on technology that converts the signal into a combination of the numbers 0 and 1.
Is the result of a technology that converts the signal into a combination of sequence numbers 0 and 1 (also called binary) to process information easily, quickly and accurately. The signal is called a bit. This digital signal has a variety of unique features that can not be found on analog technology, namely: 1. Being able to transmit information at the speed of light that can make the information can be transmitted at high speed. 2. The use of repetitive towards the information does not affect the quality and quantity of the information itself, 3. Information can be easily processed and modified in various forms, 4. It can process information in very large numbers and send them interactively. Computers process data is digitally, via electrical signals it receives or sends. In principle, the computer only recognizes two currents, namely on or off, or a term in the figure often also known as 1 (one) or 0 (zero). The combination of currents on or off is what that is capable of making a computer do a lot of things, both in introducing letters, pictures, sounds and even interesting films you watch in a digital format.
hybrid computer is a type of computer that is destined for processing the data that are both quantitative and qualitative, or with another term combines the capabilities of a digital to analog. In other words, quantitative data that is processed to produce data on the qualitative and vice versa.
