Basic Computer and Technical terms

Raster Images

Raster Graphics are  are digital images which are captured or created such an example is scanning a photo, these are built up using thousands of pixels which are used to create the form and colour of the image. Manipulating raster images to increase its size will result in a loss of quality as the system has to make up information to add the size.

Vector images 

Vector images on the other hand vector images do not lose quality when re sizing.  Vector images are built up using points and each point has a specific X and Y coordinate. These points join paths to together to form shapes and then you can further manipulate using effects and fills.

CMYK colours

CMYK is the standard colour model used to off set print full colour documents. As this type of printing uses these ink colours results may differ if the file you are working on your pc is set to RGB

RGB colours

RGB represents the colours used to display content on your screen. These colours can be used to combine and create every colour you can see onscreen.

DPI

DPI (Dots Per inch) refers to the amount of dots per inch found on a printed page. Needless to say the amount of dots defines the quality of the printed document as more dots results in a more detailed image.

PPI

PPI similar to DPI is the ammount of pixels which can be found on your digital images . The more PPI count the greater the quality of your image. 

Resolution

Resolution refers to the numbers of pixels that can be found on your screen.Your screen has a Horizontal and Vertical Axis which have a sett ammount of pixels.The more pixels you have in each of these axis the greater ammount of detail can be displayed to the user.

Pixels

Pixels are very small dots that build up the images displayed on your screen. Each pixel mixes up the 3 RGB colours to display a specific colour on screen.

GUI

GUI ( Graphical user interface ) is the interface which humans can interact with. GUI's are built up to be user friendly and created using icons, menus and windows all of which can be manipulated using a mouse.

Application

Application is a computer program which was designed to be functional for the end user. Ampplications can be split into 2 general classes

CPU

The CPU (Central Processing Unit) Is considered the brains of the computer. This is where all operations and calculations take place in a very small time.

Disk Drive

This periferal device reads data form a disk and or writes data to a disk. Different types of Disk drives can cater to different types of disks such as CD's DVDl's and Bluray Disks

Hard Drive

A storage device that can store a large amount of date which can be accessed when needed. Stored data will be permanently save unless deleted.

GPU

The GPU (Graphics Processing Unit) Is used to output the image of your display. It connects to the mothered and also includes a cooling mechanisms, memory and a processing unit of its own.

Crash

This is when your system malfunctions and can't function anymore. This can be caused my many factors such as overheating and hardware Conflicts.

Bit

All storage size measurements start from a bit. It is used to calculate the amount of space the item is taking. All other "Byte" measurements are built up from a bit such as a byte holds 8 bits and so on and so forth.

Boot 

Booting refers to when you start up your device. It will read information stored on your ROM and if no errors occur you can use your PC.

RAM 

RAM stands for random access memory and it is used to store temporary data. It holds information that is currently being used by the device. It also has a set amount of storage that limits it to a certain amount of weight for the the computer to run properly, exceeding this amount can result in slow device and crashes.

ROM

ROM stands for Read Only Memory. This type of storage is permanent and cant be accesses at any time. It is used to Boot your computer and loss of this data will not allow you to use your device properly.

USB

It is short for Universal Serial Bus, it is a standard for connecting many devices to different devices. They can be used to connect an external hard disk to a PC or connect you phone to a charger.
