BIOS stands for Basic Input Output System and is a small chip located on all motherboards. BIOS contains the information to It manages the data between the computer's operating system and attached devices such as the hard disk, keyboard , mouse , and printer . When BIOS boots up your computer, it first determines whether all of the attachments are in place and operational, then it loads the operating system into your computer's RAM from your hard disk The motherboard is the main circuit board of a microcomputer. It contains the CPU (Central processing unit), BIOS (Basic input and Output System) as well as the graphics card, sound card, hard drive, disk drives, expansion slots and external slots e.g. USB The motherboard is the main component in connecting all the computers essential parts together. A computer processor is called the CPU (Central processing unit) and is the brain of the computer. The CPU carries out the instructions of the computer by doing such things as math. The processor also communicates with all of your other components in your computer and tells them what to do. The processor carries out millions of instructions every second. This processor also links to the motherboard because the processor is located on the motherboard. Nearly all computers have heat sinks, it is located on the motherboard to help keep the CPU cool and prevent it from overheating. Overheating may cause crashes with the computer. The heat sink is a device attached to the processor chip that has fins to maximise it’s surface area to dissipate the heat. It draws heat from the processor and therefore keeps it’s temperature down The heat sink is located on the motherboard directly on top to the CPU The power supply or... ... middle of paper ... ...output system) a chip on your motherboard that contains the instructions for how your system should boot up. Specialised cards are cards specific job to do and are solely there to do that job. Specialised cards are such things such as sound, graphics and network cards Specialised cards are expansion slots which allow you to add new cards. A sound card is an expansion card for your computer that allows the input and output of audio signals. This allows you to listen to sound and if the computer didn't have a sound card you wouldn't have any sound. A graphics card is a piece of hardware installed on your computer that allows your computer to process images by rendering 3D and 2D graphics. A network card is a piece of hardware which allows the computer to communicate with a network. Nowadays, there are rarely used because most computer come with them built in.

    The supermicro P4DC6 Motherboard is a server motherboard that has the most up-to-date specifications and features. The PC motherboard was first introduced in 1960, when Digital Equipment introduced the first minicomputer (PC). The PDP-1, which sold for US$120,000, was the first commercial computer equipped with a keyboard and monitor. This motherboard was MUCH larger than the ones we see today. Today’s motherboards are merely one-tenth the size of the one’s in 1960. The SUPER P4DC6 is a little bigger than the normal ATX (8” x 10.5”) at 12” x 13”.

    The graphics processing unit or GPU has become an important part of most modern computer design. A GPU is a specialized form of processor that is implemented in a computer in order to ease the workload of the central processing unit or CPU. A GPU is also incorporated because, due to its design, it can perform certain graphics operations with greater efficiency than the more general purpose CPU. According to Denny Atkin, "More than 90% of new desktop and notebook computers have integrated GPUs" .

    The first topic for discussion is the Linux Boot Process. Just like all computers that have an operating system installed, the boot process is sequence of the actions to make sure that the operating system can turn on. With Linux Operating System it is no different from others, it requires the same process to be utilize before the client is able to take control. With the Linux O.S there are four general stages of the boot process. The first stage is the BIOS. This stage is define as the Basic Input Output system, which is loaded and the system hardware is identified. Then the POST, CMOS, and then Plug and Play are allocated. The second stage is the Boot Loader. Once the first stage is successful, the BIOS gives control to the Boot Loader program. Then BIOS searches through the Boot Loader to retrieve and load the primary boot loader code. This contain the second boot loader that contains the O.S Kernel loads. The third stage is the O.S Kernel. The Boot Loader will have loaded the kernel into memory, configured it with the location of its root filesystem, and loaded the initial ramdisk, if supplied. The new hardware and drivers are loaded and the root is mounted for the next stage. The fourth...

    There were little fans, a big green board on the back of the case with a shiny square dead smack in the middle, a big rectangular box and so much more that I couldn't comprehend. I swear I stared at these striking components for at least ten minutes just examining them. This experience is what really sparked my interest for computers and made me want to learn more about them. I put everything back together before my parents caught me taking apart a brand new computer and began researching what I saw. The big green board I saw is called a Motherboard, the shiny square I saw in the Motherboard is called the CPU/processor, the big rectangular box I saw is called a hard drive. As time went on, I kept learning more and more about this alien names. I would walk around asking my parents, "Do you know what a CPU is, do you know what a motherboard is?" I felt so cool when they had no idea what I was saying and I had to explain something to my parents instead of them explaining something to me.
