What is the power consumption of the PC (Personal Computer) in your house? To know for sure, you need to open the computer case and view it on a sticker attached to the power supply. Rated power consumption specifications as indicated by the following example:
AC INPUT
115 / 230V ~ 5 / 2.5A 50 / 60Hz
That is, the power consumption for the operation of the CPU on a house with a different default voltage is the same, namely:
At home voltage is 115V ~ 110V 5A, so the computer will operate at 115V with power consumption by 5 Ampere or equal to 115 x 5 = 575 Watts per hour.
At home is 230V ~ 220V, 2,5A, so the computer will operate at 230V with a power consumption of 2.5 Ampere or equal to 230 x 2.5 = 575 Watts per hour.
Thus, the power supply will change the voltage / voltage complying with the specifications required automatically to obtain a power of 575 Watts. What purpose changing the power supply voltage power consumption first into 115 Volt or 230 Volt, I do not understand. Power supply, has a role similar to the adapter on the laptop. Power consumption by the power supply to be modified to be accepted by the component mounted on the CPU box. In the past, these components are generally connected directly to the power supply is the monitor, hard drive, diskdrive, optical drive, processor and motherboard fan. Currently, there may be components other than those mentioned above, I am less mengetahuinya.Pada computers assembled correctly, the total power consumption of all the "innards" (components in the casing of the CPU) must be less than or (maximum) equal to the output power of the power supply. This understanding is a lot of unknown to the user (user).
In practice, many computer assemblers do not take into account the condition. This "upgrade" of certain components, such as memory chips, hard drives and processors, can lead to irregularities in the overall computer performance. Like, upgrade the memory chip, processor, video graphics cards and so on. We as consumers, generally do not understand or know the extent to which the upgrade can be allowed. 2.MATI NETWORK COMPONENTS OR TIDAKNYABERPUNGSINYA parties assemble, will generally comply with the request as long as the user can still be applied.
You will not be easily allowed to upgrade one or more units of computer components by air-brand suppliers. They tend to provide an alternative to replace all the existing devices rather than following your wishes. Why? Computer products which they marketed, have a scalable integration with an excellent work between its components. Changes in one component unit, will have an impact on the overall performance of the other component units.
Too many technical things that need to be taken into account to create a new change. Such an action is the same as making a new product development unit of which have been there before. Too much risk risking brand / brands which have been their only path to follow the will of the consumers only.
I never experienced conditions result upgrade actions that ended with damage to the motherboard unit when one of his colleagues do on a Pentium 60 to Pentium 166 at a computer assembly. Can last well over 6 months, after that ... totally dead. A. SERVERKomputer this server to provide services for a number of interconnected computers, will have access to the data, for example to access restrictions, control data, and the data flow that occurs.
is a central computer that handles a collection of data (database) and provide services to a client klient.Komputer computer can connect using a cable or wireless (wireless), if the cordless example using a connection wifi.Cara Server is working as a data storage medium of the client computer. In addition it also serves the printing server dokumen.Server we can imagine sebagia data centers and provide services such as connections or other yan services to the client computer. B. workstation is a hardware device used to request services da receives from the server in a network. Workstation or may be called clients generally have operating system with a graphical interface and has the supporting programs of service in the network, for example if we want to chat via Yahoo network, we need a workstation that installed Yahoo Messenger application. Understanding Workstation / Client Networking. As usual, this material must be very needed for you-you TKJ Students are still learning about what ituServer what it Wokstation / Client in the Network Computer.

C. HUB / SWITCH Switch is a hardware device that allows the distribusipacket data between computers on a network and is able to recognize the network topology in multiple layers so that data packets can directly get to tujuan.CONTOH IMAGES Swicth
Hub is a network device that is simple. A hub does not manage the flow of data running on the network, so every packet of data that passes through the hub will send (broadcast) to all the ports until the data packet to its destination. It can make the hub into collisions and slow down the network. (Hub is also commonly known as a repeater)
Switches and Hubs actually have the same function, because by using one of them, we can still make a Computer Network, but the use of the switch may be faster than a network hub, especially if we got a very large. HUB
5. The data transfer rate is much faster than the switch HUB
6. In terms of its economic hub is definitely less expensive than the switch

D. Network Interface Card [NIC]
NIC (Network Interface Card) or a network card is a device that provides media to connect between computers. Most cards shaped network / internal card-based, which is a network card installed in an expansion slot inside the computer. NIC function as tools that connect a network cable with a computer and a device that provides physical network addresses.
E.Kabel and Connectors
In the world of Electronic as well as in the field of computers, it's not unusual role of cables and connectors, where if there is a cable, then at both ends of the cable connector is attached.
Serves as a conductor signal cable, electric current, and data to and from electronic equipment. Connectors are the interfaces between the equipment with other equipment that plug in each port equipment.
There are some important things to know about the cable
1. Asynchronous: Not synchronized. Communication without a timing mechanism. Resulting in a timing mechanism you have communication rules. There is a bit of start and stop bits to tell the other end when the communication begins and stops.
Advantages: If one of the computers have to send data, it can do so without having to keep stalled during each clock cycle.
Disadvantages: By using start and stop bits will have a 20% overhead. In other words, if you send 100 KB of 120 KB of information is needed to get everything on your computer.
2.JENIS CABLE WITH CABLE UTP RJ45 KONEKOR and functions - UTP cable is UTP stands for "unshielded twisted pair" type of cable is made of copper conductor, having insulation of plastic and is covered with an insulating material that can protect from fire and damage physical, UTP cable consists of four pairs of twisted cable core interconnected where each pair has a different color code. Or the definition of UTP cable is a type of cable that can be used to create a computer network, either wired which on the inside contains four pairs of wires. Cables Twisted Pair Cable is divided into two types including, Shielded and Unshielded. Shielded was kind of the UTP cable has a sheath wrapping, whereas unshielded is the kind that has no casing packer. For the type of cable connection is using RJ-45 or RJ-11.
Here is a function of the UTP cable
Function UTP cable that can be used as a cable for Local Area Network (LAN) system network / computer networks, and generally UTP cable has an impedance of approximately 100 ohms, and is also divided into into several categories based on their ability as a conductor of data.
