how many keys are on the microsoft windows standard keyboard
Computer keyboard Standard alphanumeric keyboards have keys that are on three-quarter inch centers (0.750 inches, 19.05 mm)[citation needed], and have a key travel of at least 0.150 inches (3.81 mm). Desktop computer keyboards, such as the 101-key US traditional keyboards or the 104-key Windows keyboards, include alphabetic characters, punctuation symbols, numbers and a variety of function keys. The internationally common 102/104 key keyboards have a smaller left shift key and an additional key with some more symbols between that and the letter to its right (usually Z or Y). Also the enter key is usually shaped differently. Computer keyboards are similar to electric-typewriter keyboards but contain additional keys, such as the command or Windows keys. There is no standard computer keyboard, although many manufacturers imitate the keyboard of PCs. There are actually three different PC keyboards: the original PC keyboard with 84 keys, the AT keyboard also with 84 keys and the enhanced keyboard with 101 keys. The three differ somewhat in the placement of function keys, the control keys, the return key, and the shift key.
ASCII Originally based on the English alphabet, ASCII encodes 128 specified characters into seven-bit integers as shown by the ASCII chart above.[8] Ninety-five of the encoded characters are printable: these include the digits 0 to 9, lowercase letters a to z, uppercase letters A to Z, and punctuation symbols. In addition, the original ASCII specification included 33 non-printing control codes which originated with Teletype machines; most of these are now obsolete.[9]
Computer data storage Data are encoded by assigning a bit pattern to each character, digit, or multimedia object. Many standards exist for encoding (e.g., character encodings like ASCII, image encodings like JPEG, video encodings like MPEG-4).
F major F major (or the key of F) is a major scale based on F, with the pitches F, G, A, B♭, C, D, and E. Its key signature has one flat, B♭.
Command key On a keyboard made with the Microsoft Windows logo, the Windows keys are identical in function to the Mac Command keys, as is the [[Meta key|â—† Meta]] key on a Sun or another Unix-oriented keyboard.[18] Conversely, when an Apple USB keyboard is used with other operating systems, the Command keys function as Windows keys or Meta keys.
M M (named em /ɛm/)[1] is the thirteenth letter of the modern English alphabet and the ISO basic Latin alphabet.
