Bit :stands for binary digit (ie of 'bit' in Spanish referred to as bit, and to a lesser extent as bit). A bit is a binary digit numbering system. The storage capacity of a digital memory also measured in bits, because this word has several meanings.

buffer : is a memory space on a disk or in a space reserved for temporary storage of digital information digital instrument, while waiting to be processed. For example, an FFT analyzer have one or more input buffers, where digital words representing the samples of the input signal are stored. The Z-buffer is used for rendering 3D images.

Byte: (B) 1 2 (pronounced [bait] or [ 'bi.te]) is the basic unit of information used in computing and telecommunications, and is equivalent to an ordered set of bits (usually 8 bits, set April 3 May 6 7 8 9 10 which in Spanish also called octet) .11 12

The unit byte does not have symbol established internationally, although in Anglo-Saxon countries often represent as B, while in francophone countries frequently used or (of octet) .

The international standard symbol is kbit . The abbreviation kb / s corresponds to kilobit per second.

optical pencil: The stylus is an input device for computers, as a photosensitive wand, which can be used to target objects displayed on a CRT television or a monitor, in a manner similar to a touch screen manner but with higher positional accuracy. This peripheral is commonly used to replace the mouse or, less successfully, to the digitizing tablet.

LCD (English acronym liquid crystal display) is a thin, flat screen formed by a number of color or monochrome pixels arranged in front of a light source or reflector. It is often used in electronic devices batteries because it uses very small amounts of electricity.
