Computer Components
CPU
The role of this component is to direct traffic, preform calculations, store data and process instructions
CPU's are made up from millions of transistors. these are constantly increasing in amount with every new CPU. One of the first CPU's contained only 2000 whereas a newer CPU contains more than 800 million and will continue to grow.
-
Cabling- Optical cabling uses glass fibers inside an insulated case in order to achieve a higher bandwidth and better overall speeds. optical fiber cables make up a large potion of the worlds internet, telephone and television systems today.
-
Cabling- Twisted pair cabling is a very common form of cabling used in relation to computer systems this is because twisted pair cables where designed in order to stop electromagnetic interference
RAM- This stands for random access memory, the RAM sends and receives data from the CPU or processor. The ram is connected to the motherboard via the ram slots . most motherboard will have 2 to 4 ram slots so that the user can easily upgrade.
-
their are many different types of RAM form new to old laptop to desktop or ram made for mobile devices. now days we have much faster ram that has more transistors and are able to process and hold more information. an example of a newer type of RAM would be something such as SDRAM, which is all but extinct now due to new RAM such as DDR4 ..
on many newer motherboards the ram slots will be places close to the CPU slot. this allows the ram and the CPU to trans fare data to one another in less time due to their being less physical distance for the data to travel.
Heat Sink- this is the heat sink it sucks hot air from the cpu and keeps it from over heating. it is made of aluminium and copper. this is because aluminium is good at conducting heat and so this makes the cooler more efficient
-
Hard Drive- this is the primary storage for most computers. this stores most of the data and files on your computer. hard drives
-
MotherBoard
The motherboard is alos an extreamly important part of any system, this is because the motherboard in where all of the componecnts sit and it is what connects them alll. the motherboard has an intergrated bios that allows the user to tweek and change important things in relation to there system at start up. the motherboard. motherboard manufactures include major companys such as intel and MSI.
Power Supply- this is what powers the entire system, it is connected to the motherboard via a 18 pin connector. however the power supply not only powers the motherboard, it also powers the rest of system as well. it would also have connections going to the CPU and GPU as well in order to give both of these power.
-
Sound Card- this is the sound card it is attached to the motherboard through a PCI slot. the function of the sound card is to allow users to receive audio as well as output it.
-
Graphics Card- this can be a very important part for viewing videos or playing high demanding games. however if the user only plans on browsing the web and light tasks then buying a graphics card is not necessary because the motherboard comes with integrated graphics.
-
Cache memory 
This is the cache memory is sits very close to the main processor and stores information that the CPU is likely to reuse time and time again to improve performance
SATA Cable- this is the SATA cable it is connected to the hard drive and the motherboard and allows the hard drive to send and receive data from the motherboard.
-
BIOS- BIOS stands for basic input/output system and in what users will first see when they load up a new system for the first time. The BIOS of a computer system can be used in order to make important changes to the system or view system information. TO access the BIOS of a computer system the user must press a certain key when the system is boosting such as F12 in order o gain access to the systems BIOS.
-
Output device- An example of an output device in relation to a computer system would be a speaker for instance. this is classified as an output device due to it outputting audio from the computer system.
Input devices - an example of an input device in relation to computer systems would be a keyboard. a keyboard is know as an input device because it is used in order to input different data to the system.
These are speakers, these would be know as an output device. this is because they are outputting sound from the computer system that they are connected to.
Ports- There are many different types of ports located in a computer however the most common of these would have to be the USB ports. USB ports are used in order to connect many different devices to your system such as, mouse, keyboard, USB pen and so many more.
-
Ports-HDMI, these ports are also very common for modern day computer systems and are used in order to connect the actual computer system to the monitor in most cases.
-
ROM- ROM stands for read only memory and is memory that has been built directly into the systems motherboard. The ROM is what typically stores the firmware or BIOS. this ROM is very hard to modify----- and can not be done with ease.
SSD - SSD stands for solid state drive, an SSD is similar to a HDD in many ways however it is still far superior . SSDs are faster and more reliable than the average HDD and are manly used in order to store the OS as well as a few other key programs that the user wants to load more quickly
UBS pen- USB stands for universal serial bus, a USB pen is a lot like an SSD if an except the main difference between the two in that a typical USB has far less storage than a SSD however this does make it far less costly. USB pens are commonly used in order to store small amounts of work and be very portable.
