Purpose and Functions

Network Cards

This is a card that allows you to access specific networks, the method of how it gains the network depends on what network it’s suppose to access. There are 2 types of network cards:

Wireless network cards- This is when the network card looks for a network through a wireless connection.

Ethernet network cards- This is the same as Wireless network cards except it’s with a Ethernet connection.

Ethernet network cards are mostly found and used in motherboards as it connects to the router or hub and then connects to the internet.

Network cards are also used to transfer data on one computer to another by it being an interface between the computer and cable. Network cards also change the data that come from cables into bytes so the CPU of the motherboard can read it correctly.

Graphic Cards

When loading a game, the CPU can only take as much information at once, this is when the graphics card then takes this information so that the CPU can then gain more information as a graphics card, also known as a GPU, has a larger storage space compared to the CPU, this help to load programs for games, pictures etc.

PC convert the data that it’s been given into electronic signals that are then sent to the monitor. The monitor then takes these electronic signals and turn them into games and images that are clear. It’s fast enough to handle more that one type of media at once and for them to load properly.

Purpose and Functions:

Power Supply

This provided all the voltages needed for the computer in order for it to function properly. It allows the computer to take an alternating current (AC) from the household the computer is in and change it into a direct current (DC) which is the voltage a computer needs. You can usually see the power supply as it hold the fan. The functioning happens when the AC changes into DC which activated the power supply to start.

Fan and Heat Sink

Fans are needed in order for the computers CPU to not get too overheated to the point it struggles to perform its actions. Heat sinkers move the heat into another direction so that the parts in the computer can work properly and won’t break to the point it cannot be fixed. They both do a thermal check  that helps to maintain the heat that the CPU and the computer feel to make sure the computer works well.

Purpose and Functions:

USB Port

t allows you to save documents and software’s compared to RAM as  RAM can easily if there’s no power that RAM can run on then hard disks such as USB ports allow the items to be saved as well as be portable and placed into other computers. It functions as soon as the USB is placed in the side area where the USB port is held.

USB Port

ROM

This stands for Read Only Memory. Rom’s were created by IC chips, IC chips make it easier to have larger circuits as well as helping with the space ad energy use etc. this helps to start up the computer. BIOS tells the CPU to access hard drives, videos and usual inputs such as keyboards and mouse’s, this is how ROM is started up. The memory on a ROM is kept even when the computer is turned off.. It cannot be changed through programs or by the user but it keeps or stores the instructions of hoe th=o start the computer when it’s turned on.

RAM

RAM is used to store temporary programs or data that are being used on a computer.  This allows the processer to access each program and data quickly. RAM stands for Random Access Memory. It functions when the computer is turned on as it runs all the programs ready to be opened but when turned off, the RAM card stops running. The operating system, applications and graphics user interface (GUI) is all stored onto the RAM.

RAM

DRAM

This is a quicker type of RAM that is used for personal computers or workstations. It also needs refreshing every millisecond through storage cells. Stands for Dynamic Random Access Memory. It functions when the chip is slotted into its area. The same place where a RAM would be slotted.

DRAM

SRAM

It quicker than RAM as it doesn’t need to be refreshed. Stands for Static Random Access Memory.  It functions when the chip is slotted into its area. The same place where a RAM would be slotted.

Purpose and Functions

4 Main hard drives

SATA

Serial Advanced Technology Attachment. SATAs function is to transfer data from components such as a CPU ,  CD-ROM and RAM to the motherboard. SATA replaced IDE hard drives, also known as PATA (Parallel Advanced Technology Attachment) as it has a larger storage, inexpensive, supports hot plugging (such as a USB), quicker transfer of data.

IDE

Integrated Drive Electronics. IDE’s connect to CD drives and Hard drives of a motherboard, it then transfers the data and instructions between both devices. It has a Maximum compatibility but doesn’t have a lot of support when it comes to new technology as it doesn’t support hot-plugging hard drives.

IDE was created in 1986 making it fairly old, showing the reason for why it can’t support new technology whereas SATA was created in 2003 making it more continent as it also allows hot-plugging.

      

SCSI

Small Computer System Interface. SCSI disks are seen to be similar to IDE had drives. SCSI spins at a quicker rate compared to both IDE and SATA as these both spin around 7,200 while SCSI spins at 10,000- 15,000. SCSI need to be controlled or it could lead to a fast breakdown also, it functions the line (interface) between the drives ad the computers motherboard.

SSD

Solid State Drive. Compared to the other hard drives. SSD is a component that needs to be moved as SSD uses semiconductors, as there’s no disk that need spinning, this means that it’s more faster as well as having a lower chance of breaking. But, compared to the other hard disks, it’s more expensive.

Another connection of a hard drive to a computer would be:

USB

This is the most common as it’s simple as you plug it in the USB port. And as soon as the USB is plugged in, the user is able to read and save files immediately.

FireWire

This is like a USB except it’s more faster, making it more popular as it is faster especially when transferring videos.

Purpose and Functions:

Motherboards

To provide connections between all computer parts. However, it doesn’t store any information. Motherboards cannot function without at CPU (Central Processing Unit) or a RAM card (Random Access Memory).

motherboards

CUP

This is a chip that starts up the programs and reads instructions as well as putting out data. Without this chip, the motherboards wouldn’t work. It starts to function as soon as the ‘on’ button on the motherboard is pressed from by the user.

CPU

BIOS

It allows certain actions to perform as soon as the computer is turned on and runs the first stages of starting up the computer. It also makes sure that the system is correct with the memory that has been loaded. It could also help with the security of the computer. It’s the first software that takes control of the computer. BIOS stands for Basic Input/output System. When loading, the BIOS takes a POST test, this stands for Power On Self Test, this makes sure that the computer meets all it’s requirements, if the test fails then it beeps to indicate the fault of the computer.

ICT with Japan

Japan has got this app that translates Japanese into: English, Mandarin and Korean, and other languages

it’s the latest thing in Japan and is used for work business to speak to different languages and cultures, it was just released this month and has developed other products of Lexifone and Vocre it has been a success but my personal view for the future of this info is that it might go down hill so trains and aeroplanes will be in use rather that phone calls and chat-rooms but they will soon add to this app French, German, Indonesian, Italian, Portuguese  Spanish and Thai in late November, but the reason i think it will go down hill is because it might have too many languages on it so it has too many to choose from and will just get confused….
