The UK variant of the Enhanced keyboard commonly used with personal computers designed for Microsoft Windows differs from the US layout as follows: . The UK keyboard has 1 more key than the U.S. keyboard (UK=62, US=61, on the typewriter keys, 102 v 101 including function and other keys, 105 vs 104 on models with Windows keys)
The symbol # is known variously in English-speaking regions as the number sign, [1] hash, [2] or pound sign. [3] The symbol has historically been used for a wide range of purposes including the designation of an ordinal number and as a ligatured abbreviation for pounds avoirdupois – having been derived from the now-rare ℔ .
The arrangement of the character input keys and the Shift keys contained in this layout is specified in the US national standard ANSI-INCITS 154-1988 (R1999) (formerly ANSI X3.154-1988 (R1999)), [2] where this layout is called "ASCII keyboard". The complete US keyboard layout, as it is usually found, also contains the usual function keys in ...
Hash key may refer to: Number sign , also known as the number, pound or hash key, a key on a telephone keypad For its use in data structure, database and cryptographic applications, see hash function or unique key
On IBM PC compatible personal computers from the 1980s, the BIOS allowed the user to hold down the Alt key and type a decimal number on the keypad. It would place the corresponding code into the keyboard buffer so that it would look (almost) as if the code had been entered by a single keystroke.
A typical 105-key computer keyboard, consisting of sections with different types of keys. A computer keyboard consists of alphanumeric or character keys for typing, modifier keys for altering the functions of other keys, [1] navigation keys for moving the text cursor on the screen, function keys and system command keys—such as Esc and Break—for special actions, and often a numeric keypad ...
These two keys are commonly labelled star, , and number sign/hash, #, respectively, and produce the signals associated with those symbols. These keys were added to provide signals for anticipated data entry purposes in business applications, but found use in Custom Calling Services (CLASS) features installed in electronic switching systems .
A universal hashing scheme is a randomized algorithm that selects a hash function h among a family of such functions, in such a way that the probability of a collision of any two distinct keys is 1/m, where m is the number of distinct hash values desired—independently of the two keys. Universal hashing ensures (in a probabilistic sense) that ...
