Computer Questions Short Answers - duty assignment Example09- How/why is a pegleg focusing really a data movement steeringANS A branch instruction is not a data movement instruction because branch instruction jump from one instruction to another but dont move data from one instruction to another.10- How can the speed at which an electrical circuit performs its function be increasedANS Acircuitis an continuous loop of conductive material that allows electrons to flow through continuously without beginning or end.Generally as the feature size shrinks, almost everything improves-the cost per unit and the switching power consumption go down, and the speed goes up. 11- What be the advantages of gallium arsenide (as compared to silicon) for the implementation of microprocessorsANS It has smaller molecular size and thusly (in theory) smaller circuits can be fabricated from it. It has both electrical and optical properties.12- Why does the reliability of magnetic storage media genera lly diminution as recording density increasesANS Higher density room less surface welkin per bit. Less surface area per bit means less mass of coercible material. Less coercible mass means reduced ability to hold a charge high enough to be reliably commemorate and to allow for magnetic leakage, decay, and other destructive factors.13- What factors contribute to the loss of data stored on tapesANS If administration crashes leading to incomplete sessions.Hardware problems causing incorrect or incomplete write operations pervert media or databases.Due to malicious external agents like viruses and hackers14- What are the advantages of optical data storage devices as compared to magnetic data storage devicesANS optical storage devices are read by... ANS Optical storage devices are read by a laser beam. Generally they have a to a greater extent limited storage capacity when compared to magnetic devices. However, one advantage is that they are more hard habiliment than magnetic devi ces.ANS When you decrease the lover size you increase the number of outside loop operations, and thus you increase the load on the CPU. When you computer gets too busy it may not complete the buffer loop in time to deliver its samples to the mixing bus, which, in turn, has to deliver to the driver/soundcard. The result leave behind be unpleasant cackling noise.ANS Code 39 (also called Code 3 of 9) is an easy-to-print barroomcode commonly used for variant bar-coding labels such as name badges, inventory and industrial applications. The Universal Product Code was the first bar code to be widely adopted from as early as April 1973 by the US mart industry for product marking. Code 2 of 5, sometimes called Code 2 from 5 and the interleaved 2 of 5 barcodes can represent the digits 0-9. In use since the late 1960s, it is a popular choice for airline tickets, video developing envelopes and internal warehouse systems.ANS Bar code scanners are manufactured to read the
