Data and commands that can't be physically touched, ‘behind the scenes’. If a key is pressed on the
keyboard, the processing done through the CPU and all the components.
Where all the commands go to be directed to the right component.
RAM(Random Access Memory)
A bit like the hard drive, this component stores memory. It stores memory in a smaller size. Rams come in sizes ranging from 256MB to 8Gb Per piece. Ram stores memory for a certain amount of time. If the computer is shut off, the memory is lost forever unless backed up before the shut down.
Storage Media
This includes he hard drive, external hard drive. These are components that store things for as long as they can. Until they become faulty or until you format (Erease all content) it.
Cache
A memory cache, sometimes called a cache store or RAM cache, is a portion of memory made of high-speed ram instead of the slower and cheaper ram used for main memory. Cache saves memory just like ram but does it faster.
Single core processor
A core can be seen as a tube. The data has to go from one side to the other to be processed. No matter how
many commands, a single core can not process them on any more than 1 tube (1 core)
Dual core processor
Just like a single core, but with an extra tube to handle data in a more sufficient and faster way.
DVD
DVD (digital versatile disc) is a digital optical disc storage format, invented in 1995. DVDs offer higher storage capacity than compact discs while having the same dimensions.
UMD
Umd is an optical disc medium developed by Sony for use on their PSP (Playstation Portable) handheld gaming and multimedia platform. It can hold up to 1.8 gigabytes of data
Adress Bus
An address bus is a port on the Pc usually integrated on the motherboard. Different address buses have different pattrens I.e lines that connnect with the same pattren on compatible devices.When a processor or DMA-enabled device needs to read or write to a memory location, it specifies that memory location on the address bus (the value to be read or written is sent on the data bus).
Capacitor
In a way, a capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. A capacitor is much simpler than a battery, as it can't produce new electrons, it only stores them.
Optical Disk
An optical disc is a flat, usually circular disc which encodes binary data in the form of pits (binary value of 0 or off, due to lack of reflection when read) and lands (binary value of 1 or on, due to a reflection when read) on a special material (usually aluminium ) on one of its flat surfaces.
Magnetic Tape
Magnetic tape is a medium for magnetic recording, made of a thin magnetizable coating on a long, narrow strip of plastic film. It was developed in Germany, based on magnetic wire recording.
Transistor
A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals changes the current through another pair of terminals.
Binary
Binary describes a numbering scheme in which there are only two possible values for each digit: 0 and 1. The term also refers to any digitalencoding/decoding system in which there are exactly two possible states.In digital data memory, storage, processing, and communications, the 0 and 1 values are sometimes called "low" and "high," respectively.
MHz
Abbreviation for megahertz. One MHz represents one million cycles per second. Cclock speed, is measured in megahertz. For example, a microprocessor that runs at 200 MHz executes 200 million cycles per second.
Ghz
Abbreviation for gigahertz. One GHz represents 1 billion cycles per second. The clock speed, often is measured in gigahertz. For example, a microprocessor that runs at 200 GHz executes 200 billion cycles per second.
Hard Drive
Just like other storage media devices, the hard drive stores media on it. However it works much faster than other devices for example a usb drive or a CD and a hard drive executes actions much quicker.
Quad Core
A quad-core processor is a chip with four independent units called cores that read and execute central processing unit (CPU) instructions such as add, move data, and branch.
Data Bus
Databus may refer to: A data bus is a computer subsystem that allows for the transferring of data from one component to another on a motherboard or system board, or between two computers. This can include transferring data to and from the memory, or from the central processing unit (CPU) to other components.
