Task 1-Defining key words


Portability:

Allows information and data to be transferred from different places in hardware and software easily through using another system or device. Forms of portable devices include USB sticks and floppy discs which allow information from one computer to be transferred onto another computer by moving the files.

Convergence:


This is the coming together of two or more technologies in the same device. An example of this is a mobile phone, it allows you to play games and also allows you to go on the Internet.

Interactivity:

It allows people to communicate and interact with other people live via computer technologies, for example webcams and microphones. These are a great help for long distance conversations and sending messages immediately to another person. It is used in the business world for video conferences and even between relatives who live far apart and want to communicate with each other. This is able to happen because of the access to the Internet that most people globally have access to.

Compatibility:

There are two types of compatibility forward and backward compatibility. Forward compatibility is when a system allows later versions of itself to work on it. Backward compatibility is when a system allows older versions of itself to be used on its system. For example a Sony PlayStation 3 allowing Sony PlayStation 2 games to be played on its system.

Storage:

It allows the connection to other devices allowing them to share infromation. Is a technological device that also allows files to be stored on itself, they can be a variety of different sizes and have different amounts of capacity. For example USB sticks, floppy discs, CD ROMs etc.


Miniaturisation:

It is the process of technology getting smaller and having the potential to store more information and increase the device's portability. An example of this is the Imac air, which i sa extremely compact laptop created by the institution Apple. Another example is the Sony PSP it is like an ordinary Sony PlayStation2 but is portable and much smaller not needing the aid of a television to make the images of the game visable as they have their own screen.

Digital:

Digital is the way in which data of all typesd is stored using the binary code of 0 and 1. It is what replacing analogue in things such as televisions, very soon there will be no analogue televisions as they will all have been replaced by digital televisions as they are said to be of a better quality. This is called the 'digital switch-over'. However there are some problems in areas in the UK where the signal is not the best so the picture will go pixelated and block out the visual and audio features for a few seconds. Digital systems use discrete, discontinuous values to represent information for input, processing, transmission and storage. In contrast to this analogue systems use a continuous range of values to represent information. Although digital representations are discrete the information shown can be either discrete (numbers, letters and icon). Or it can also be continuous (sounds, images, and other measurements of continuous systems).

Connectivity:

It is the communication between two or more computer systems. These systems are usually connected by the Internet, which is a very infamous way of linking up computers but more local ways are established.

Synergy:


It is the way media institutions try to use their various products to sell their other products. For example if you buy an Apple Ipod then you can get your music for it from Apple Itunes and get this software loaded up onto your Apple Imac.
