Transcript of Computer Parts
The motherboard is a printed circuit board and it is located at the middle of the computer case. It allows the CPU, RAM, and all other computer hardware components to function and communicate with each other.
SATA cables are long, thin, 7-pin cable. SATA cables are used to connected devices like optical drives and hard drives to the motherboard. One end plugs into a port on the motherboard, usually labeled SATA, and the other into the back of a storage device like a hard drive.
Heatsink is a component designed to lower the temperature of an electronic device by dissipating heat into the surrounding air. All modern CPUs require a heat sink. Some also require a fan. Heat sinks are generally made of an aluminum.
The SSD or the solid state drive has no moving parts, which gives it advantages such as accessing stored information faster, produces no noise, often more reliable, and consume much less power than the hard drive found in computers. The first SSD was implemented in IBM supercomputers in the 1970s. The SSD uses non-volatile memory as a means of storing and accessing data.
A HDD is also know as a hard disk drive it's job is to keep its data even when you hit the power button to turn it off. The hard drive is the computers main storage device that permanently stores all data on the computer. The hard drive was first introduced on September 13, 1956 and consists of one or more hard disc platters inside a air sealed casing.
Graphics cards or the gpu is used to display pictures on the screen of you monitor. The graphics card decides how to use the pixels on the screen to create the image. It then sends that information to the monitor through a cable. When you play games the gpu has to make a wire frame out of straight lines and then add lighting, texture and color in sixty times per second.
A computer case or tower is enclosure and contains most of the components of a computer. Computer cases usually include sheet metal enclosures for a power supply unit , as well as a rear panel that can accommodate connectors from the motherboard and expansion slots. Most cases also have a power button or switch, a reset button, and LEDs to indicate power status and network activity. Some cases include built-in ports such as USB and headphone ports on the front of the case.
The PSU also know as the power supply provides power to all of the different components in the computer. The power supply converts the alternating current (AC) line from your home to the direct current (DC) needed by the computer parts. The power supply gets power from the wall and then sends that power to all the parts in the computer.
RAM or random access memory is very fast, faster than a hard drive. When you turn off the power the ram losses all of it's data unlike the hard drive witch keeps its memery.RAM is the most common type of memory found in computers and other devices, such as printers. Ram memory can be accessed randomly depending on what you are doing.
The CPU or the centrol processing unit is the brains of the computer where most calculations take place. In the computer case the cpu is the most important part of a computer. It is responsible for interpreting and executing most of the commands from the computer's hardware and software. After running even a short time, modern CPUs can get very hot. To help dissipate this heat, it is necessary to attach a heat sink and a fan directly on top of the CPU. The CPU is usually square with many short metallic connectors on its underside. Some older CPUs have pins instead metallic connectors.
An expansion slot is a socket on the motherboard that is used to insert an expansion card which provides additional features to a computer such as video, sound, advanced graphics, Ethernet or memory. Depending on the form factor of the case and motherboard, a computer system generally can have anywhere from one to seven expansion slots.
A sound card is an internal computer expansion card that allows the input and output of audio signals to and from a computer under control of computer programs. The sound card is able to provided the computer with the ability to produce sounds that can be heard by the user either over speakers or headphones.
A Ribbon cable is a cable with many conducting wires running parallel to each other on the same flat plane. As a result the cable is wide and flat.The ribbon cable was invented in 1956 by Cicoil Corporation, a company based in Chatsworth, California. The company's engineers figured out how to use a new material, silicone rubber, to 'mold' a flat cable containing multiple conductors of the same size
A universal serial bus (USB) flash drive is a small, portable device that plugs into a computer's USB port. Like a hard disk, a USB flash drive stores information, but with a flash drive you can easily transfer that information from one computer to another.
A computer fan is any fan inside, or attached to, a computer case used for active cooling, and may refer to fans that draw cooler air into the case from the outside, expel warm air from inside, or move air across a heat sink to cool a particular component.
USB ports allow stand-alone electronic devices to be connected via cables to a computer. USB allows data to be transferred between devices. USB ports can also supply electric power across the cable to devices without their own power source.
DVD is a digital optical disc storage format, invented and developed by Philips, Sony, Toshiba, and Panasonic in 1995. DVDs can be played in many types of players, including DVD players. DVDs offer higher storage capacity than compact discs while having the same dimensions.
In electronics and technology, a reset button is a button that can reset a device. On video game consoles, the reset button restarts the game, losing the player's unsaved progress. On personal computers, the reset button clears the memory and reboots the machine forcibly.
An optical disc drive is a disk drive that uses laser light or electromagnetic waves to read or write data to or from optical discs. Some drives can only read from discs, but recent drives are commonly both readers and recorders, also called burners or writers.
An audio port on a computer is any receptacle or jack to which an audio device such as speakers, headphones or a microphone can be connected. All laptops and some desktops have built-in speakers, but for better sound or privacy, you will need to connect external audio through one of the ports.
A molex connector is a 4-pin connector. Certain Molex connectors are used for providing power to the motherboard, fans, hard disk drive, floppy disk drive, CD/DVD drive, video card, and others.
