Random Access Memory, or RAM is the physical hardware inside a computer that temporarily stores data serving as the computer’s working memory. The Purpose of RAM is to provide quick read and write access to a storage device. Your computer uses RAM to load data because it’s much quicker than running that same data directly off of a hard drive.



A hard disk is part of a unit, often called a “disk drive that stores and provide relatively quick access to large amount of data on an electromagnetically charged surface or set of surfaces.Today’s computers typically come with a hard disk that contains several billion bytes(gigabytes) of storage.




A battery is a hardware component that supplies power to a device, enabling that device to work without a power cord. Batteries are often capable of powering a laptop computer for several hours depending on how much power it requires. Today, many high-end devices such as computer laptops and cell phones use rechargeable batteries that allow a user to recharges the battery once depleted of energy the picture below is an example of what a laptop battery may laptop battery may look may look like when removed from the laptop, with a close_up of the battery rating.





A Wi-Fi card connects to your laptop either in your USB port or a wider card slot. This card generally is geared to go a particular Wi-Fi network, so to use it you must be in range of a wireless Internet signal dedicated to that network. In this way the Wi-Fi card acts as both a receiver and transmitter. It receives the wireless signal and communicates with the wireless network, enabling you to access the Web with your laptop.





A PCMCIA card is a credit card-size memory or I/O devices that connects to a personal computer usually a notebook or laptop computer. The most common example of a PCMCIA card is the 28.8 Kbps modern for notebook computers.






Referred to as a floppy or floppy disk, a floppy diskette is a type of storage media, capable of storing electronic data, like a computer file. The floppy diskette was first created in 1967 by IBM as an alternative to buying head drives, which were extremely expensive at the time.





Digital Versatile Disc or Digital Video Disc, a DVD or DVD-ROM is a disc capable of storing large amount of data on one disc the size of a standard compact Disc. CD/DVD drives were first sold in 1997. They are widely used used for storing and viewing movies and other data. The picture of the Matrix DVD movie disc is an example pf a DVD movie.



 Speakers are one of the most common output devices used with computer system. Some speaker are designed to work specifically with computers while others can be hooked up to any type of sound system. Regardless of their design of their design, the purpose of speakers is to produce audio output that can be heard by the listener.





A Exhaust fan is any fan inside or attached to a computer case under 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. Generally these are found in axial and sometimes centrifugal forms. The former is sometimes called a “electric fan”




The CPU in a computer is the brain, the place where all of the processing occurs. CPU speed often correlates directly with overall computer speed though the hard drive speed and the amount of memory play a big role in this too. CPU speed is measured in gigahertz with a higher number representing the number of processes the CPU can handle at once. It follows that a higher number indicates a faster computer and to a large extent that’s true though you won’t notice any difference between a 2.1 – and 2.2 Ghz processor.


 A heat sink is an electronic device that incorporates either a fan or a Peltier device to keep a hot component such as a processor cool. There are two heat sink types: active and passive.

Active heat sinks utilize the power supply and are usually a fan type or some other Peltier cooling device. If you are looking to purchase an active heat sink, we recommend purchasing fans with ball – bearing motors that often last much longer than sleeve bearings. Sometimes these types of heat sinks are referred to as an HSF, which is short for heat sink and fan. 

Passive heat silks are 100% reliable, as they have no mechanical components. Passive heat sinks are made of an aluminium-finned raditor that dissipates heat through convection. For passive heat sinks to work to their full capacity there should be a steady airflow moving across the fins. The above picture is an example of a heat sink that is both active and passive.



An adaptor is a special device for connecting electrical equipment to a power supply or for connecting different pieces of electrical pieces of electrical or electronic equipment together.






 The motherboard is the main circuit board of your computer and is also known as the mainboard or logic board. If you ever open your computer the biggest piece of silicon you see is the motherboard. Attached to the motherboard you’ll find the CPU, ROM memory RAM expansion slots, PCI slots, and USB ports. It also include controllers for devices like the hard drive, DVD drive, keyboard, and mouse. Basically the motherboard is what makes everything in your computer work together.



An LCD or Liquid Crystal Display, is a type of screen that in many computers TVs digital cameras tablets and cell phones. LCDs are very thin but are actually composed of several layers. Those layers include two polarized panels, with a liquid crystal solution between them.

The liquid crystal do not emit light themselves, so LCDs require a backlight. that means that an LCD requires more power and could potentially be more taxing on your phone’s battery. LCDs are thin and lights though, and generally inexpensive to produces.
