What is the name of the operating system which was originally designed by scientists and engineers for use by scientists and engineers?
Polling is the process where the computer or controlling device waits for an external device to check for its readiness or state, often with low-level hardware. For example, when a printer is connected via a parallel port, the computer waits until the printer has received the next character.

The process of accessing information on CD ROM is random. Random access minimizes the data access time. It helps in fast retrieval of related data items in a database. In a random access drive, the data and files are not stored in any specific order.

See lessDuring boot-up, the memory test:
Most tests involve a series of pen-and-paper tests and questions, each of which carries a score. These tests assess a number of different mental abilities, including: short- and long-term memory. concentration and attention span.

See lessWhen you are testing a fuse, you should set the Volt-OHM meter to what scale?
Set your ohmmeter to the lowest scale on the resistance setting. Usually, it will have Ω (Greek letter omega) for resistance. When testing a fuse, touch the end of each ohmmeter cable to the opposite ends of the fuse. A reading between 0 and 2 indicates continuity—the circuit is good/complete.

See lessWhat resistance in ohms should be displayed when testing a speaker in a computer?
If you have a 4 ohm (impedance) speaker, it could measure the resistance on the multimeter between 2 and 3.4 ohms, an 8 ohms speaker could measure between 5 to 7 ohms, and a 16 ohms speaker might measure between 12 to 14 ohms. If a speaker measures very low or no resistance, then it is bad.

See lessWhich best describes a fragmented hard drive:
A fragmented hard drive is similar to a huge, jumbled-up load of laundry, where all the different clothing types and colors are mixed up. Once the HDD is defragmented, the system performance improves because all the jumbled-up data is reorganized and stored appropriately.

See lessAn anti static strap uses a small _____ to make sure you do not become the least path of resistance to the ground?
Final answer: The proper use of an anti-static wrist strap involves not attaching it to any grounded object, not using it with an anti-static mat, attaching the clip to a painted section of the computer case, and ensuring it makes direct contact with the skin.

See lessWhich provides the fastest access to large video files?
The fastest access time is found in semiconductor memories. Magnetic tapes, magnetic discs, compact discs, and other older memory have higher access times. Memory access times should be fast enough to keep up with the CPU; else, clock cycles would be wasted.
