Question

In the context of computers, the time taken to receive data from a storage device or to obtain data from a peripheral unit is known as _______.
1. Time sharing
2. Downtime
3. Time slicing
4. Access time

Answer 1

Correct Answer - Option 4 : Access time

The correct answer is Access time.

• In the context of computers, the time taken to receive data from a storage device or to obtain data from a peripheral unit is known as Access time. 

• Peripheral devices
  • A peripheral device is any device that can be connected to a computer.
  • This term includes monitors, keyboards, mouse, webcams, drawing pads, joystick, modems, printers, scanners, interactive whiteboards, drive wheel, and so on.
• Computer access time is commonly measured in nanoseconds or milliseconds and the lower the time the, better or faster the computer should perform.
• Ideally, the access time of memory should be fast enough to keep up with the CPU. If not, the CPU will waste a certain number of clock cycles, which makes it slower.
  • DRAM (dynamic random access memory) chips for personal computers have access times of 50 to 150 nanoseconds (billionths of a second).
  • Static RAM (SRAM) has access times as low as 10 nanoseconds.
