Processing How the Computer Works

Posted onCategoriesGeneral Article

The Central Processing Unit or CPU (Central processing unit) acts to process the commands given by computer users, managing them together with the data on the computer. The processing unit or device will also communicate with input, output and storage devices to carry out interrelated instructions.

In the original von Neumann architecture, he explained a Unit of Arithmetic and Logic, and a Control Unit. In modern computers, these two units are located in an integrated circuit (IC – Integrated Circuit), which is usually called the CPU (Central Processing Unit).
The Arithmetic and Logic Unit, or Arithmetic Logic Unit (ALU), is a tool that performs basic implementations such as arithmetic (additions, subtractions, and the like), logical execution (AND, OR, NOT), and comparisons (for example, comparing as many contents two slots for equality). In this unit the actual “work” is carried out.
The control unit stores the current commands made by the computer, instructing the ALU to execute and retrieve the information (from memory) needed to execute the command, and move the results back to the appropriate memory location. This unit functions to control the reading of computer program instructions.


Input and results
I / O allows computers to get information from the outside world, and put their work there, can be physical (hardcopy) or non-physical (softcopy). There are various types of I / O devices, from familiar keyboards, monitors and disk drives, to more unusual ones such as webcams (web cameras, printers, scanners, and so on.
What all ordinary input tools have is that they encode (convert) information from one type into data that can be further processed by a digital computer system. Output tool, decodes data into information that computer users can understand. In this sense, digital computer systems are examples of data processing systems.


Instructions
The commands discussed above are not commands like human language. Computers only have a limited number of simple, well-formulated commands. The usual command that most computers understand is “copying cell contents 123, and imitation places in cell 456”, “adding cell contents 666 to cell 042, and place due to cell 013”, and “if the contents of cell 999 are 0, your next command in cell 345 “.
The instructions are represented on the computer as the numbers for “copying” might be 001, for example. A set of special commands supported by a particular computer is known as the computer machine language. In practice, people don’t usually write commands for computers directly in machine language but use “high-level” programming languages ​​which are then translated into machine language automatically by special computer programs (interpreters and compilers). Some programming languages ​​are closely related to machine language, such as assembler (low-level language); on the other hand, languages ​​like Prolog are based on abstract principles that are far from the actual implementation details by the machine (high-level language).

Computer parts
The computer consists of 2 major parts, namely software and hardware.
Hardware
• Processor or CPU as a unit that processes data
• RAM memory, a place to store

A computer is a tool used to process data according to the procedures that have been formulated. The word computer was originally used to describe people whose work performed arithmetic calculations, with or without tools, but the meaning of this word was then transferred to the machine itself. Its origin, information processing is almost exclusively related to arithmetic problems, but modern computers are used for many tasks that are not related to mathematics.

In that sense there are tools such as slide rules, types of mechanical calculators ranging from abacus and so on, to all contemporary electronic computers. A better term suitable for broad meanings such as “computer” is “information processing” or “information processing system.” Over the years there have been several different meanings in the word “computer”, and several different words are now called computers.
The word computer has generally been used to define people who do arithmetic calculations, with or without auxiliary machines. According to the Barnhart Concise Dictionary of Etymology, the word was used in English in 1646 as a word for “one who counted” and then by 1897 it was also used as a “mechanical calculating device”. During World War II the word refers to American and British female workers whose work counts the way of war artillery with a counting machine.
Charles Babbage designed one of the first calculating machines called analytic machines. In addition, various simple machine tools such as slide rules can also be said to be computers.

1. The computer is a useful and sophisticated industrial product.

The computer that we know today is the result of the development of electronic and informatics technology so that the original computer form is large and places to eat, now in the form of a small with great capabilities. The advancement of the IC electronic component industry (integrated circuit) has encouraged the creation of a variety of IC chip devices that are diverse and support various purposes of manufacturing electronic products. The advancement of electronic technology cannot be separated from the progress in the field of knowledge and processing of semiconductor materials, especially silicon.

The benefits of computers today are quite diverse ranging from writing aids, drawing, editing photos, playing videos, playing songs to analyzing data from research results as well as operating programs to solve scientific, industrial and business problems. The world of children has long known game play tools that are controlled by computer systems. In the industrial sector, computers have been used to control high-precision production machines (for example CNC, a versatile machine in the metal industry) so that we can find various metal industrial products that are varied and we imagine it difficult to do manually. There are also many machines in the garment industry equipped with computer controls, for example a body hat company can produce caps with uniform embroidery quality in large quantities in a short time. In trading companies such as department stores have been used cash register machines (cash register) that are equipped with computer controls so Read More
