Computers are tools used to process the data according to procedures that have been formulated . Computer word originally used to describe people who perkerjaannya
perform arithmetic calculations , with or without the tools , but the meaning of this 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 that sense there are tools such as slide rules , mechanical calculators types ranging from abacus and so on , until all contemporary electronic computers . The term better
suited for a broad sense 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 referred to referred to as the 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 to calculate artillery war path 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 . The computer industry is the result of sophisticated beneficial .
The computer as we know it today is the result of the development of electronic technology and computer informatics so that its original shape and eating places are large ,
now small shaped with great ability . The progress of industrial electronic components IC ( integrated circuit) has prompted the creation of various IC chips diverse devices
support a variety of purposes and manufacture of electronic products . Advances in technology electronics are not separated from the advancement of knowledge and
processing of semiconductor materials , especially silicon .
Benefits computers today are quite diverse ranging as a tool to write , draw , edit photos , play video , play a song to the analysis of research data and to operate the
programs completion problems of scientific , industrial and flying businesses . The world has long known son game tool controlled by a computer system . In industry , the
computer has been used to control production machinery with high precision ( eg CNC , a versatile machine in the metal industry ) so that we can find a variety of metal
products industry varied and we imagine is difficult if done manually . Many of the machines in the garment industry are equipped with computer control , for example, the
company can produce bodir cap hat with embroidery uniform image quality in large quantities in a short time . In trading companies such as department stores have used a
cash register ( cash registers ) are equipped with computer control so that the machine can only be controlled by the manager of his room alone . In education , in addition to
tools found as a lesson , many laboratory instruments are equipped with a computer so that the tool can work more closely to overcome obstacles and barriers to the human
senses . From the field of education and research that uses such tools generated a variety of useful research results that do not taste has been widely used in people's daily
life a lot . Various drugs either for human health as well as agriculture and animal husbandry has been widely used by the public . In the field of biotechnology , the
equipment has a lot of culture that comes with the computer controls the precise work to commercialize sterile space . 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 to do manually by a pilot , an aircraft can be controlled automatically so that it can fly safely at your destination .
Similarly, the magnitude of the benefits of computers , for it is introduced in this paper on a computer and how to assemble them . In this paper did not explain carefully how
to build an electronic circuit to build a computer or computer software ( software ) , in order to know this you still have to study in the fields of Electronics and Information
Technology . This paper is not intended that any of you know or understand computers , you can know with computer parts , assemble them and get to know how it works ,
especially knowing how to operate the software application then you will feel the benefits of such a large computer . Here again is not elaborated on the history of the
invention of the computer , you just need to believe that the computer industry is the result of utilizing a variety of research and testing results of bebeberapa scientific fields .
For example, the scientific field of electronics , informatics , management , materials chemistry , materials physics , physical chemistry , electrochemistry and others.It was a
couple of computer technology which will be released in 2010 , if viewed from a technology and sophistication is to come in 2010 tabhun really - really quite fantastic .
TriBook with three ultra wide -screen concept that is 21 ? the width of the screen . He also has an 8x SuperDrive , 1TB hard drive , and the MacBook Pro - caliber CPU , plus a
trackpad multitouch keyboard ,2 . HOW TO WORK COMPUTERmemoryIn this system , memory is a numbered sequence of bytes ( such as " cell " or " pigeon hole " ) , each
containing a small piece of information . This information may be a command to tell the computer what to do . Cells may contain computer data necessary to carry out a
command . Each slot may contain one , and what is now the data might then be perintah.Memori storing various forms of information as binary numbers . The information
will not be solved in the form of binary ( 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 of solving . More complex instructions could be used to store images , sound , video , and various kinds of
information . The information can be stored in a single sell is called a byte .
processingCentral Processing Unit or CPU ( Central Processing Unit ) serves to process the orders given by computer users , managing shared data on the computer .
Processing units or devices will also be communicating with the input devices , output and storage to implement inter-related instructions .
In the original von Neumann architecture , he describes an Arithmetic and Logic Unit , and a Control Unit . In modern computers , the second unit is located in a single
integrated circuit ( IC - Integrated Circuit ) , which is commonly called a CPU ( Central Processing Unit ) .Arithmetic and Logic Unit , or Arithmetic Logic Unit ( ALU ) , is a tool
that performs basic implementation such as the implementation of arithmetic ( addition , subtraction , and the like ) , the implementation of the logical ( AND , OR , NOT ) ,
and the implementation of comparison ( eg , compare the contents of as many as two slots for equality ) . In this unit do " work " the truth.The control unit saves the current
command is performed by a computer , instruct the ALU to carrying out and get back information ( from memory ) required to execute the command , and move back the
results to the appropriate memory location . This unit functions to control reading computer program instructions .Feedback and resultsI / O allows a computer to get
information from the outside world , and his work put in there , can be physical ( hardcopy ) or non-physical ( softcopy ) . There are various kinds of tools I / O , from the
familiar keyboard , monitor and disk drive , to the more unusual such as a webcam ( web camera , printer , scanner , and so on .Owned by all the usual input devices is that
they encode ( convert) information of a kind to the data that can be further processed by a digital computer system . Tool output , decode the data into information that can be
understood by the computer user . In this sense , the digital computer system is an example of a data processing system .instructionsCommands discussed above is not
the command like human language . The computer only has a limited number of simple commands are properly formulated . Ordinary commands that are understood most
computers are " copy the contents of cell 123 , and a 456 cell clone in " , " add the contents of cells 666 to 042 cells , and the result in cell 013 " , and " if the contents of cell
999 is 0 , the next command you in cell 345 " .Instructions are represented as numbers in a computer - code for " copying " may be 001 , for example . A special set of
commands that are supported by a particular computer is known as machine language . In practice , people usually do not write orders for computers directly in machine
language but using a programming language " high level " which is then translated into machine language automatically by special computer programs ( interpreters and
compilers ) . Some programming languages ​​are closely related to machine language , assembler ( low level language ), on the other hand , languages ​​like Prolog are
based on abstract principles far removed from the actual implementation details by machine ( high level language ) .3 . Computer partsThe computer consists of 2 major
parts of the software ( software ) and hardware ( hardware ) .hardware
Processor or CPU as the data processing unit
RAM memory , a place to store temporary data
Hard drives , semi- permanent storage medium
Input devices , media used to enter data to be processed by the UPS , such as a mouse , keyboard , and tablet
Output device , the media used to display the output of CPU processing , such as monitors , speakers , plotters , projectors and printers
software
operating system
Base program on a computer that connects users with computer hardware . The operating system used is Linux , Windows , and Mac OS . The task of the operating
system , including ( but not only ) set of program execution on it , the coordination of input , output , processing , memory , and software installation .
The computer program
An application is installed in accordance with its operating system
Slots on the computer
ISA / PCI slot for additional input of non - graphics card
AGP / PCIe slots for additional graphics card input
IDE / SCSI / SATA , slots for hard drives / ODD
USB media input slots for plug - and-play ( plug and play , meaning that devices can be connected directly to a computer and can be used ) .
4 . TYPES OF COMPUTERAnalog computer is a term used to describe a computing tool that works at the level of the analog . Level analogue here is the opposite ( dual ) of a
digital level , which is the digital level voltage levels 'high ' ( high ) and 'low ' ( low ) , which is used in the implementation of a binary number . Basically , an electronic
component which is used as the core of an analog computer is the op - amp ( operational amplifier ) .digitalAdalah computer computer machine that was created to process
quantitative data in the form of numbers, letters , punctuation , and others. Which pemrosesnya implemented based technology that converts the signal into a combination of
the numbers 0 and 1 .Is the result of 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 . The digital signal has a range of unique features that can not be found on analog technology , namely : 1 . Being able to
send information at the speed of light that can make the information can be transmitted at high speed . 2 . Repeated use of the information does not affect the quality and
quantity of the information itself , 3 . Information can be easily processed and modified into various shapes , 4 . 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 knows only two currents , ie on or off , or terms
in the figure are often also known as 1 ( one ) or 0 ( zero ) . The combination of the current on or off is what that can make the computer do many things , both in introducing
letters , images , sounds , and even interesting films that you watch in a digital format .hybrid computer is a type of computer that is dedicated to the processing of data that
are both quantitative and qualitative , or with other terms combine digital with analogue capability . In other words the quantitative data is processed to produce data on the
qualitative and vice versa .
