Computer systems Unit 3 task 1
I am creating a beginners guide towards computer systems, so you can get the basic understanding of what they are and I will give a reference to technical specification. Task 1
Internal System Unit components:
• CPU
• BIOS
• MOTHERBOARD
• HARD DRIVE
• PORTS
• SPECIALEZED CARDS
CPU:
A Central Processing Unit (CPU) is the hardware within a computer that carries out the instructions of a computer program by performing the basic input/output operations of the system. The two most popular CPU brands are AMD and Intel. These processors are found in a variety of electronics varying from laptops, phones, desktops and gaming consoles.
This is a technical specification for AMD A10 6800K Processor with:
• FM2
• 4.4…show more content… Printer, input devices e.g. Camera and cabling e.g. Twisted pair. I will explain all of them so you get the basic understanding of what they are.
Output devices:
Monitor:
The monitor is piece of computer hardware that makes you able to see the resolution. A monitor displays the graphics information and video resolution generated by the computer through the video card.
Printer:
The printer is a device that accepts text and graphic output information from a computer and transfers the information onto paper, usually to standard size sheets of paper (A4). It can be useful because it produces a hard copy of the information and then you can move around with the information on paper.
Speakers:
Speakers are popular output devices used with computer. They receive audio input from the computer's sound card and produce audio output. Most computer speakers have an internal amplifier, which allows you to increase the volume.
Input devices:
Camera:
A camera is an input device that is used to take images and allows them to be stored and saved in the computers memory. Once taken the images can be saved or deleted and can be exported and shared to different…show more content… It can send live pictures to another location by means of the Internet. Some webcams are connected by the USB port, however some webcams can be wireless and can connect them to the computer by Bluetooth etc.
Scanner:
A scanner is an input device that is an opposite of a printer in a way. It scans documents such as photographs and pages of text and when a document is scanned, it is converted into an electrical and digital format. This creates an electronic version of the worded document and then can be viewed and edited on a computer.
Microphone:
The microphone can be connected to a computer by the USB port or wirelessly. A microphone is a device that captures audio by converting sound waves into an electrical signal. They can be used for a range of things like to communicate with others or if the computer already has a built in microphone it can be used to increase the quality of it.
Cabling:
Optical:
Optical fiber cable is a type of cable; it has a number of optical fibers bundled together, which are normally covered in protective plastic covers. Optical cables are used to send digital data signals up to distances of hundreds of miles with higher through put rates than those achievable electrical communication cables. An advantage of the optical cabling would be that one single mode fiber could replace a metal of time larger and
