Back-up - a copy or copies of programs, data, digital assets etc..., that can be used to restore a system in the event of a catastrophic failure. Backups might be on another hard drive, or on tape, or both.
Binary - in the context of computing, having two states e.g. 0 and 1, or True and False.
In everyday counting we use decimal or base 10, which means that each number's position has a value of 10 times the value of the position to its right. In binary counting, which has a base of 2, each number's position has a value of 2 times the value of the position to its right.
A decimal number, take 126 for example, which we read without thinking as one hundred and twenty six, is the sum of each of the values according to their position. In this case, and reading from the left, Hundreds + Tens + Units. Thus for 126 add together 1 Hundred + 2 Tens + 6 Units.
Binary counting uses exactly the same principle, except that whereas in decimal a new position is added to the left after reaching ten, in binary a new position is added after reaching 1. Thus the binary representation of decimal 7 is 0111, where in decimal terms the column values in this example are Eight, Four, Two and One. Hence adding as for a decimal number, 0 Eights + 1 Fours + 1 Twos + 1 Ones = decimal 7.
Bit - a contraction of Binary Digit, abbreviation 'b'. A digital (as opposed to analogue) computer recognises only two states in the smallest item of information available to it - typically represented as 0 and 1. This smallest available item of information is called a Bit.
Because digital computers can only recognise two states, they can only count, or do anything for that matter, by counting from nought up to one and then starting again. In practice ordinary desk and laptop computers process 16 or 32 strings of Bits in parallel.

Bit depth - see colour depth.
Bitmap - a matrix of dots, the colour value of each which are stored in one or more Bits, to represent an image. A bitmap file type has the extension BMP.
Boolean searching - Boolean algebra is used for solving logic as opposed to arithmetical problems, and elements of Boolean notation can be used when searching data. The most commonly used elements are AND, OR and NOT, where for example 'house' AND 'tree' will find all items with both house and tree in their indexed data, 'house' OR 'tree' will find items with either house or tree, and 'house' NOT 'tree' will find items with house, but which do not have tree in their indexed data.
Brand Asset Management Software - Also see Brand Asset Management Systems
Brand asset management system - a system for keeping track and ensuring the consistent application of the digital resources used to define a company's brand, the logos, colours, graphics, images etc... for publicity material, documentation, websites and so on. Key requirements include the ability to easily and quickly store any type of file, and crucially, to then be able to search for and find them when they're needed again.
Branding - in the context of web based systems, the look and feel of the site, including the banner, colours, fonts, logos and general layout.
Browser - the software used, for example, to look at things on the web. Internet Explorer, Safari, Firefox etc... are examples of browsers, whatever you're using now to look at this.
Browser based - when a media asset management or online library system is said to be browser based, it means the programs, assets and databases are stored centrally with none on the user's computer. It also means that the system is always accessed through a browser - whether for administration, uploading and editing, general searching etc... .
Byte - usually 8 Bits and abbreviated as 'B'. A byte can have 28 = 256 unique states.
A kilobyte (KB) is 1,000 bytes (strictly 210 = 1,024 bytes), a megabyte (MB) is 1,000,000 bytes (strictly 220 = 1,048,576 bytes), and a gigabyte (GB) is 1,000,000,000 (one thousand million) bytes (strictly 230 = 1,073,741,824 bytes).
