COMPUTER COMPONENTS COMPONENTS are generally divided into two parts, the main and additional components. The main components are an absolute must have for your computer to be turned on. If any one of these components is missing, the function of the computer can not run as they should be. An example is the Sound Card, RAM, Hard Disk, Processor, VGA, etc.. As for the additional components, its function as a supplement so that the computer can be used for other work, and does not affect the whole computer when it does not exist. Examples of Computer Components generally like USB Card, Scanner, Printer, Speakers, etc..Main Computer Components• The motherboard is the most important component to a Computer. Her Indonesian is the parent board. It is so called because most of the main Computer Components will be installed in the slots on the component. The shape of the motherboard include slots attached to it will continue to change as technology changes other components. Therefore we must be careful to choose a suitable component for motherboards that we have. In addition to its main function to put the other main component, the other function is to split the incoming flow in each component. Therefore, choose a motherboard with an appropriate and ask for advice to the experts.• Processor can be called as the brain to a computer, because it is the component that has a function to perform the calculation and execution of the commands we give. Types of processors are constantly changing as development era. The components that are closest to the processor heatsink fan, whose function is to cool and is always located very close to the processor die to prevent overheating.• Random Access Memory or RAM is a component whose function is to temporarily store all the data from the entire program processed Components Computers that are running. In its development, the technology is always followed by a numbering RAM. Ranging from the old DDR, up to the latest current DDR3.• Video Card is the component that serves to connect or translate produced from computer to monitor. This component is important because how could we know what is happening on your computer without the visual aid of the monitor. When grouped, then nothing has been integrated VGA directly on the motherboard, and some are added through additional slot on the motherboard. By providing additional VGA on the computer, it will add visual quality produced by the monitor.• Sound Card as the name suggests serves to produce sound, where there is also integrated directly with the motherboard and nothing can be added to a particular slot on the motherboard. With additional soundcard, will certainly add to the quality of the sound produced.• Hard Disk is a place to store all the data in the form of video, audio, text, etc.. In addition to the amount of storage capacity that is different, there is now a solid state disk technology which is no longer using the optical system as the old hard drive. With this new technology, the speed of read and write data on the hard disk would be faster and would withstand the shock.• Optical Disc Drive or what we used to know as a cd room; dvd room; etc. Components Computers are used to read and write the disk media.• Monitor is a component that is used for the discharge of visual images or video. Monitor the technology even now have a variety, such as tubes and flat-panel monitors.• Keyboard and mouse are Computer Components used to enter commands to the computer. Without these two components, the only functioning computer that can run automatically by itself.• Power Supply is used to supply power to your computer. That need to be considered in selecting these components is the power needed Computer Components must be in accordance with the power that can be supplied by the power supply.• Casing is a component in the form of a container to put the motherboard plus other components attached to it. Therefore choose the size of the casing which is considered sufficient to accommodate all the needs of hardware we need.Additional Computer Components• LAN card or a network card, also known as the link between one computer to another computer.• Modem is a communication component to send and receive signals from two directions. The main function of which we know is for the Internet network.• USB stands for Universal Serial Bus is used for connecting. We often use this component to connect the phone; flash disk; digital cameras, etc.; with our computers.• Printer and Scanner Components Computers are additional inputs and outputs. Printers used to produce prints from processed that we make through the computer. Scanner used to memintadi images, text, photos or other documents which are then stored in a file.• Speaker is a component of the sound of the processed sound card. The sound quality of the computer also influenced the type of speakers used.• Bluetooth, wifii, or other wireless network is a Computer Components has the function to move data from one device to place a limit areas.

How to care for computer components

How to perform maintenance and cleaning peripherals (components) on the computer, it is advisable to be this way and proper procedure, because the peripherals with each other peripherals that have different shapes and sizes, so that each component has a sequence or each other's way in the treatment and cleaning components.How to treat or clean your PC components are:1. Casing TreatmentCasing / Box / Box likened to an example of a building or a place to store all components and peripherals to the needs of computer completeness. Thus, the appearance of the casing also needs maintenance or cleaning for appearance casing looks beautiful and clean, like a house clean and tidy.
      A computer case consists of: Power Supply, Fan, Led Indicator, Switch, Power Button and Reset Button.
      Computer case needs to be cleaned regularly, beauty routine, beauty and success. This is to avoid interference or dirt caused by dust, dirt and other animals that can be a problem on computer components such as: Motherboards, VGA Card, Sound Card, Modem, Fan and others.The tools are used to clean the computer case: brushes, cloths, wipes, duster and vacuum cleaner. How to clean the inside of the casing is to unscrew the casing, then wipe on the motherboard, fan, etc. with equipment that has been provided, while for the outside you just clean up with Kais duster.
2. Care CD-ROMIn accordance with the development of today's computers, each time you buy a PC (Personal Computer) definitely comes with a CD-ROM that can only be read, CD-R / W that can be read and written or DVD. Utilities CD-ROM, CD-R / W or DVD is not just for listening to music (multimedia) only, can also be used for storing data, and installation purposes. CD-ROM can be distinguished according to the speed, ranging from speed 8x, 16x, 24x, 32x, 40x, 48x, 52x, 60x. The higher the speed, the more expensive the sale price.How to clean CD-ROM/CD-RW/DVD are as follows:1. Turn on the computer2. Pour the liquid cleaner to CD Cleaner3. Insert the CD into the CD Drive Cleaner4. Wait a while, until the process is complete cleaner
3. Disk MaintenanceHard drive is the device from a PC and is a very important component in a computer, because the hard drive serves as a media tool for storing data, such as the operating system, programs and data base and hard drive belonging to the external memory.Principle of disk performance "the faster spins, the faster the performance." Because the speed of the hard drive can be seen from the unit disc rotational speed data per-minute expressed in units of rpm, the higher the rpm the faster the transfer of data. Sample unit disk speed was 5400 rpm, 7200 rpm, and so on.How to take care of the hard drive are as follows:1. Use the software, by doing, scandisk, defragmentation or doing low-level format.2. To reduce the heat, use a cooling fan (Cooler) on the hard drive.3. Turn off your computer with the correct procedure, it means do not carelessly turn off the computer.4. Avoid dust.5. Perform routine checks.
4. Treatment VGA CardVGA Card stands for is (Video Graphics Array) or (Video Graphics Adapter) or can also be called with the Display Adapter, which is a piece of equipment or a computer component that serves to process the graphics output on the screen. How to install VGA card must match the slot on the motherboard, such as the type must be installed on the AGP slot is AGP slot berwarana chocolate, and a manifold mounted on a PCI slot PCI slots are white. Each type of AGP slot and VGA Card have different voltages. Usually the problem is often the case that the excessive heat.How to care for VGA Card is as follows:1. VGA Card must be frequently cleaned of dust or dirt with a brush or with other peraalatan.2. Fan should be frequently cleaned of dust or dirt with a small brush or a medium.3. Tighten the Fan position, if the fan is loose.
5. Memory CareRAM (Random Access Memory) is the external memory and the primary component of which is the space to store programs or data that can be written and read by a processor in a computer. RAM acts as a temporary storage medium, because it is affected by the state of electricity. If power outages automatically, then the stored data will be lost. The bigger / smaller RAM capacity will affect the fast or slow the process of the program. The types of RAM include: EDORAM, SDRAM, DDR and RDRAM.How to treat RAM is as follows:1. Do not often apart pairs of RAM as it can cause corrosion and damage.2. Do not touch kaki-kaki/PIN often located at the bottom of the RAM, as it can lead to damage from static electricity.3. Clean using the cleaning fluid.4. Clean by using karen eraser.5. Check and tighten the position of RAM in order to work with the maximum.
6. Care Power SupplyPower supply functions convert AC current into DC current to be distributed to the various components of the computer. Power unit from the power supply capacity: 150 watts, 300 watts, 400 watts and 500 watts. Suggested select and buy a quality power supply or at a reasonable price, the good and stable performance.How to take care of the power supply are as follows:1. Install the stabilizer on the PC, to reduce the performance of the power supply and prevent excessive heat released by the power supply.2. Note the smooth round fan, if the fan is not good rotation will cause excessive heat.3. Clean dust or dirt from inside the power supply.4. Do not get too close to put the power supply to the air vents, as this may cause the temperature is around the casing will cause moisture and can damage components become rusty.
7. Treatment CPU / Processor (Central Processing Unit)CPU or processor is the chip or commonly known as Mikrosprocessor, and the CPU is the brain of the computer. Processor speed depending on the speed, the unit of measure processor Megahertz (MHz), and even now reached gigahertz (GHz), starting at 1 GHz, 2 GHz, 2.4 GHz, 2.6 GHz and even reach 3:04 GHz. The bigger the size the faster the process. Processor brands include: Intel, AMD, Cyrix, IBM, Athlon, Duron, Via and others.How to take care of CPU (processor) is dbawah like this:1. Note the location of the fan, plug in the correct position so that air can rotate smoothly.2. Keep the processor fan with higher spin, eg 5400 rpm or above.3. Try to use a heatsink that tebuat conductor of copper or aluminum.4. Try before being installed, apply silicon grease on the back of the processor in order of heat more smoothly.
8. Treatment MotherboardMotherboard is a place or the mother of all computer components such as processors, VGA Card, Modem, Sound Card, Lan Card, FDD, IDE cable, and so on are used to synchronize the components with one component to another and depends on the type of the installed chipset. In the motherboard there is a lot of data lines (Bus) which connects from processor to memory, from the chipset to the hard drive connector and others.How to care motherboard as follows:1. Clean with a brush or vacuum cleaner.2. Keeping the temperature3. Trim cable pathways by binding for air circulation can run smoothly.9. Printer CareThe printer is a tool used to produce prints of writing (text), images via paper or film.How to maintain the printer is as follows:1. Clean the outside of the printer from dust or dirt with a dry cloth, paper towels, cleaning fluids, water and so on.2. Avoid printer from direct sunlight, and avoid printer from a non-permanent temperature and humidity.3. Do not shake the ink cartidge, may cause leakage of ink in cartidge.4. Do not touch the IC chips on a cartidge, as it may cause damage to the cartidge.5. Do not insert foreign objects into the printer.6. Avoid contact with spilled liquid into the printer.7. Place the printer on a flat and ventilated.8. Do not turn off the printer when the ink charging process is underway.

Jumper function on ComputerJumper on a computer is actually a connector (interface) were associated electrical circuitry used to connect or disconnect a circuit. Jumper is also used to set up the electrical board as a computer motherboard.
Let us focus on a Jumper on a computer. Jumper is a computer function is used for setting the computer equipment as necessary. Fortunately we were at this time setting it through the Defense has begun to decrease its use. Therefore, all function settings are now using outo settings making it easier for the user or computer assembler to not much use Jumper.
Jumper on the computer is usually used on motherboards, Disk and Optical Disk, and in some certain VGA card. But because its use more in the motherboard and hard drive, and Optical Disk, then we will only discuss three.Jumper on Motherboard
1. Clear CMOS Jumper

Jumper on the computer is usually used on motherboards, Disk and Optical Disk, and in some certain VGA card. But because its use more in the motherboard and hard drive, and Optical Disk, then we will only discuss three.Jumper on Motherboard
1. Clear CMOS Jumper
 CMOS jumper is usually located near the CMOS battery. Usually there are 3 feet (pin) on this jumper. Its function is to store and reset the CMOS (an IC program on Motherboard) in the default position (Initial Setting / Factory).Usually the pin to 1 and 2 when connected to a CMOS Jumper the normal position will save any settings that we change the CMOS / BIOS. And if we change the Jumper positions 2 and 3, then the computer will return to the default position.Then what was the default position? Of course, if we do the wrong setting the CMOS / BIOS then if an error occurred that resulted in the computer can not live, then by Clear CMOS computer will return to its original position before we make changes to the CMOS / BIOS.
Similarly, Clear CMOS Jumper can be used if the computer can not we do the change of life due to the hardware, such as processor, but because CMOS / BIOS settings you have stored on computers that are old and not able to read the processor you just replace the Jumper can be you use.
Jumper is also used if you forget the password that you created in the BIOS. By doing Clear CMOS, then the password that you create will disappear by itself.2. Jumper Bus Clock / Bus Speed
 Jumper serves to set your clock to the processor bus. At this time, almost exactly jumper is rarely used. Setting function that had been organized by the jumper now made outo or can be set via the BIOS.
In the picture is one example of a computer Pentium I, which consists of Bus 50, 55, 60, 66 and 75. These buses are on the processor. In every bus that we choose, there are instructions on the use of jumper.
3. Jumper Bus RatioLike the jumper Bus Clock / FSB, this jumper can practically not be reused. Jumper is a multiplication ratio of the processor. For example, processor Pentium I 133 MHz Bus / FSB 66, then the ratio is 2x. Then we do the settings according to the instructions contained in the information in both motherboard and manuals.4. VGA JumperJumper is usually found on the motherboard that provides VGA onboard VGA as well as additional slots. Jumper, usually consisting of 3 legs / pins are used to select whether to use its onboard VGA or VGA slot. Just like-bus clock jumper, jumper has been rarely used and replaced with outo setting, so without doing any setting, VGA will choose which one is used alone.5. Jumper Audio
 Jumper Sound, is the jumper used to enable voice. Jumper is usually composed of 10 pins lined up with the pin number 8 is empty. If you enable audio in front casing, then automatically, in case the socket Audio Audio has enabled this jumper. But if not, prepare a jumper to connect pin number 5 and 6, as well as pin number 9 and 10, otherwise the sound will not come out even if drivers have entered. And these events often occur where the audio can not be heard and the people who do not understand the confusion and thought onboard Sound of Your motherboard died.
6. USB Power Jumper
Have you ever experienced something you can not function USB? or works only on Windows? Not in the DOS (eg by use of a USB keyboard)? Maybe you do not enable USB Power Jumper.
Jumper is on almost all motherboards with USB Socket. Jumper is composed of 3 legs / pins. If not installed, then your USB will not work. When in pairs on one leg, eg pin 1 to pin 2 or pin 2 to pin 3, it will have a different effect. That one will not be able to enable USB in DOS.
7. Jumper Memory / RAMJumper is usually found on the motherboard that has a memory slot 2 types of facilities, such as Motherboard with SDRAM and DDR1 memory slots, or DDR1 to DDR2, it is to choose one memory slot jumper settings required.
Jumper on the hard drive or optical disc (CDRom, DVD, etc.)
 jumper on the hard drive and Optical Disk usually to determine the status of the hard disk or optical disk. Status of the hard drive / optical drive if he will be a master (master) or slave (slave).It is important to be noticed when we did tundem (merging disk to hard disk, or optical disk drive with one cable). When both master status, then they will not be detected by the motherboard. Therefore one must be a master (master) and the other a slave (slave).
In particular motherboard, the status of slave (slave) on a single hard drive (without doing tundem) will not be detected by the motherboard.
Regarding the Master and Slave status information can be found on the label on the hard drive. CMOS jumper is usually located near the CMOS battery. Usually there are 3 feet (pin) on this jumper. Its function is to store and reset the CMOS (an IC program on Motherboard) in the default position (Initial Setting / Factory).Usually the pin to 1 and 2 when connected to a CMOS Jumper the normal position will save any settings that we change the CMOS / BIOS.

1. Types of Computer Networks By The scale• Local Area Network (LAN) :: a computer network that connects one or more local computer to connect or communicate, and usually use a HUB / Server. LAN networks are generally constructed in one space such as a home or office.• Metropolitant Area Network (MAN) :: similar to the local area network (LAN), but includes the entire city or campus. MAN formed by connecting multiple LANs. Thus, MAN greater than LAN but smaller than a wide area network (WAN). MAN highly efficient and provide fast communication with a high-speed operators, such as fiber optics.• Wide Area Network (WAN) :: A WAN connecting over a LAN, and is used for a larger geographic area. WAN similar to the banking system, in which hundreds of branches in various cities are connected to each other to share their official data. A WAN works the same way as a LAN, only on a larger scale. Normally, TCP / IP is the protocol used for the WAN in combination with devices such as routers, switches, firewalls and modems.2. Types of Computer Network Based Functions• Peer-To-Peer (P2P) :: the computer is connected directly to one another, do not use enhancements such as a bridge or server as a liaison. So this one is a computer network that can communicate between computers directly with one another either in software or hardware.• Client - Server :: computer network requires a server computer as an intermediary between the client computer. serves to control access between the client u / communicate with other computers.3. Types of Computer Network Based on Network Topology• bus topology :: All computers in the network are connected with the main line (backbone), generally referred to using a regular cable (BUS). All computers can be connected in a network by using mediautama (BUS)• Topology star / star :: jaringa computer is most commonly used at the present time, computers - computers connected via a concentrator such as Switch, HUB or both. So the computer can be connected to another computer safely, although one of the computers are fine, the other computers are not affected and can still be connected.• Topology ring / token ring :: computer network model similar to the ring, one computer with other computers connected like a circle, for example, the first computer is connected to two computers, two computer to computer terhung three rivals and that, until the last computer will return to computer first. but the network this computer has the disadvantage that if one computer is broken / troubled the computer network also problematic.• Topology netting or mesh topology :: a network of computers connected to the computers directly to other computers that are on the network. So, in a mesh topology every computer can communicate directly with the destination computer. (Id.wikipedia.org)• Topology tree :: type network coupled between BUS topology and star topology. This topology consists of a collection of star topology are connected in a BUS topology as the main (backbone). Computers connected to the hub, while the other hub connecting the main line. (Id.wikipedia.org)4. Types of Computer Network Based on data transmission medium• Wired Network (Wired Network) :: A computer network that uses cables, so to connect a computer to another computer in the form of a network cable connecting required. The function of the network cable to send information between computers in the form of electricity network.• Wireless Network (WI-FI) :: a network that uses electromagnetic waves. These networks do not need a longer cable to be connected between the computer with other computers, because this network only uses electromagnetic waves that would send a signal information between networked computers.

History of computer networks
 The history begins with the birth of the computer network computer network concept in the 1940s in America was initiated by a computer development project MODEL I at Bell labs and research group led by Harvard University professor Howard Aiken. [3] At the beginning of the project is to utilize a computer equipment to be used together. [3] To do some process without wasting lots of empty time made the streak (Batch Processing), so multiple programs can be run on a computer with the rules of the queue. [3]Year later 1950s when the type of computers began to grow until the creation of a super computer, a computer must serve some places available (terminal), for it was discovered the concept of time-based distribution process known as TSS (Time Sharing System). [4] So for the first time form a network (network) computer was applied. [4] In the TSS system of multiple terminals connected in series to a computer or other device connected to a network (host) computer. [4] In the process of TSS is starting to look a fusion of computer technology and telecommunications technology that was originally developed on their own. [4] U.S. Department of Defense, the U.S. Defense Advanced Research Projects Agency (DARPA) decided to conduct research that aims to connect several computers to form an organic network in 1969. [5] research program is known as the ARPANET. [5] In 1970, already more than 10 computers were successfully connected to each other so that they can communicate with each other and form a network. [5] And in 1970 it was also after the workload increased and prices large computing devices began to feel very expensive, then start to use the concept of the distribution (Distributed Processing). [3] In this process some of the host computer doing a great job in parallel to serve multiple terminals which are connected in series in each host computer. [3] In distribution process is absolutely necessary blend of deep between computer and telecommunications technology, because in addition to the process that must be distributed, all must serve the host computer terminals in a single command from a central computer. [3]

 In 1972, Roy Tomlinson managed to complete the program electronic mail (email) he made a year ago for the ARPANET. [5] The program is so easy to use, it immediately became popular. [5] In the same year ie 1972, the icon at (@) is also introduced as an important symbol that shows the "at" or "on". [5] In 1973, ARPANET computer network was developed to expand outside the United States. [5] Computer University College in London, was the first computer that is out Americans who are members of Arpanet network. [5] In the same year ie 1973, two computer experts that Vinton Cerf and Bob Kahn presented a bigger idea, which became the forerunner of thought International Network (Internet). [5] The idea was presented for the first time at the University of Sussex. [5] historic day following the date of March 26, 1976, when the Queen of England managed to send e-mails from the Royal Signals and Radar Establishment at Malvern. [5] A year later, more than 100 computers that join in the ARPANET to form a network or network. [5]Tom Truscott, Jim Ellis, and Steve Bellovin, created the first newsgroups called USENET (User Network) in 1979. [6] In 1981, France Telecom creates something new with the launch of the first TV phones, where people can call each other the also associated with a video link. [6]As we get computers that make up the network, it takes a formal protocol that can be recognized and accepted by all the networks. [6] To that end, in 1982 established a Transmission Control Protocol (TCP) or better known as the Internet Protocol (IP) which we known to date. [6] Meanwhile, in Europe appears a similar network known as Europe Network (Eunet) which covers an area of ​​the Netherlands, England, Denmark, and Sweden. [6] This Eunet Network provide electronic mail and USENET newsgroups . [6]For a uniform address existing computer network, then in 1984 introduced the Domain Naming System or the domain name system, which we are now familiar with DNS. [5] Computers connected to the already existing network of more than 1000 computers more. [5] In 1987 , the number of computers connected to the network has jumped 10-fold to 10000 more. [5]Computer networks continue to grow in 1988, a national Finnish Jarkko Oikarinen discover and introduce the Internet Relay Chat or better known as the IRC that allows two or more computer users can interact directly with the delivery of messages (chat). [6] As a result, a year later number of interconnected computers soared 10-fold. [6] no less than 100 000 computers to form a network. [6] In the summer of 1990 is the most historic year, when Tim Berners Lee designed a programe editor and explorer who can menjelajai one computer with others to form a network. [6] programe is called Waring Wera Wanua or the World Wide Web. [6]Computers that are connected to form a network has exceeded a million computers in 1992. [5] And in the same year the term surfing (surf). [5] And in 1994, the sites on the internet has grown to 3000 pages address, and for the first time shopping via the internet or virtual-shopping or e-retail appear on the site. [5] In the same year, Yahoo! was founded, which was also the year of birth as well as Netscape Navigator 1.0. [5]
