GF(2)
(also denoted \mathbb F_2, or \mathbb Z/2\mathbb Z) is the finite field with two elements. is the Field (mathematics), field with the smallest possible number of elements, and is unique if the additive identity and the multiplicative identity are denoted respectively and , as usual. The elements of may be identified with the two possible values of a bit and to the Boolean domain, Boolean values ''true'' and ''false''. It follows that is fundamental and ubiquitous in computer science and its mathematical logic, logical foundations. Definition GF(2) is the unique field with two elements with its additive identity, additive and multiplicative identity, multiplicative identities respectively denoted and . Its addition is defined as the usual addition of integers but modulo 2 and corresponds to the table below: If the elements of GF(2) are seen as Boolean values, then the addition is the same as that of the logical XOR operation. Since each element equals its opposite (m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Z2 (computer)
The Z2 was an electromechanical (mechanical and relay-based) digital computer that was completed by Konrad Zuse in 1940. It was an improvement on the Z1 Zuse built in his parents' home, which used the same mechanical memory. In the Z2, he replaced the arithmetic and control logic with 600 electrical relay circuits, weighing over 600 pounds. The Z2 could read 64 words from punch cards. Photographs and plans for the Z2 were destroyed by the Allied bombing during World War II. In contrast to the Z1, the Z2 used 16-bit fixed-point arithmetic instead of 22-bit floating point In computing, floating-point arithmetic (FP) is arithmetic on subsets of real numbers formed by a ''significand'' (a signed sequence of a fixed number of digits in some base) multiplied by an integer power of that base. Numbers of this form .... Zuse presented the Z2 in 1940 to members of the DVL (today DLR) and member , whose support helped fund the successor model Z3. Specifications See also * ...

Kawasaki Z2
''For the 1970s two cylinder 750, see Kawasaki 750'' The Kawasaki Z750, also called Z2, is a four cylinder motorcycle made by Kawasaki as part of their Z series, introduced in 1973 for the Japanese market. Regulations at the time mandated a maximum capacity of , so the Kawasaki Z1 could not be sold in Japan. Visually the Z2 is similar to the Kawasaki Z1, with the main difference being the smaller displacement. The new 746 cc engine was built with newly designed pistons and crankshaft parts to give it a feel similar to the Z1's 900 cc four cylinder engine. The engine had a maximum output of 69ps at 9,000 rpm and could propel the Z2 to a maximum speed of 170 km/h. Production of the Z2 began in March 1973 and the bike recorded sales that were 10% higher than its nearest 750 cc competitor. The bike was featured heavily in the anime and manga series ''Great Teacher Onizuka'' as well as its predecessor ''Shonan Junai Gumi is a Japanese manga series written and illust ...
