Component presentation

  1. 1. Component Presentation<br />
  2. 2. Mother Board<br />A motherboard is the backbone of a computer unit it makes communication between the other components within the unit possible and it is where all the wires for the power buttons sounds lights and the hard drives etc. The motherboard has every component in the computer connected to it all the hard drive ram graphics card and network card connected to it through wires.<br />
  3. 3. CPU<br />The Central Processing unit(CPU) that is normally inserted into the motherboard this is the brain of the computer and it is normally has a fan which goes above it to make sure it doesn’t over heat and break the CPU. And so the CPU is running at its best. The CPU is the brain of the computer and there is a slot in the motherboard where it is placed and the CPU itself cannot run on its own it needs other programs to translate other codes to it so it knows how to run the codes its being asked to run and the cpu keeps everything going with <br />
  4. 4. RAM<br />Ram is inserted this determines the performance of the machine and these are plugged directly into the motherboard. These also temporary holds data which is needed by the processor for example games, videos etc. RAM stands for random access memory and this temporally stores data while the computer is on so the hard drive isn’t read all the time and when a computer is turned off the information on the ram is gone and this type is called volatile type of memory. The ram plugs into the modem riser slot on the mother board so that it fits and runs through the motherboard.<br />
  5. 5. Hard Drive<br />The Hard drive which holds the data that is stored on the computer and the hard drive plugs into the motherboard through the use of sata cables this is depending on the type of Hard drive and motherboard it is and also has a cable from the power plugging into it so that it is able to work. The memory can be accessed through the options on the computer. Read Only Memory is normally on the hard drive already. It stores data onto metal discs within the device and it can store terabytes of information most computers now have a c drive already on.<br />
  6. 6. ROM<br />Rom or read only memory is a type of storage for media and it can not be modified it can only be viewed. On a computer the programs that are on it need to be some sort of non-volatile memory so it doesn’t start to go wrong and the ROM does this because it can be edited by anyone and this keeps the original safe. ROM storing is only really good for information and programs that are not expected to be changed during the devices life.<br />BIOS<br />The BIOS is typically placed in a ROM chip that comes with the computer. This makes sure that the BIOS will always be available and will not be damaged by disk failures. It also makes it possible for a computer to boot itself. Because RAM is faster than ROM, but many computer manufacturers design systems so that the BIOS is copied from ROM to RAM each time the computer is booted.<br />
  7. 7. Graphics Card<br />The Graphics card shows helps show images on the computer but some cannot show a lot maybe only a few images and the OS model but the bigger and better ones can help play games and such. The card is connected to the Motherboard and some graphics cards have there own built in fans that they are powerful to keep them cool but the graphics cards use the power that is received in the motherboard through the battery. And then the socket for the graphics card sticks out the back plate and then the vga cable is linked to the monitor to show the screen.<br />
  8. 8. Network Card<br />The network card is how the computer can access the internet though using Ethernet cable but firstly the Network card is slotted into the motherboard it works as then putting in the Ethernet cable in to get it working with the network the Ethernet socket sticks out of the back plate and it then ready to connected with a Ethernet cable. Also network cards can be wireless and but is still installed the same as a normal network card.<br />
  9. 9. Power Supply<br />Computers have to have a power supply which takes power from the wall and outputs power at specific voltages on specific cable formats within the computer. Network Cards but these now are normally built into the motherboard and don’t need to be inserted because they are normally now built in.<br />Connecting the comonents<br />All of the components for the computer is all connected to the motherboard in some way or another with wires. The Hard drive and CD drive is connected to the motherboard by using sata cables and the power supply and the LED cables from the case link into the motherboard also for lights and power buttons. And the cards themselves graphics and network cards plug into the motherboards and the cable sockets stick out the computer back plate with all the cables inside the computer.<br />
