Light travels at a speed of 299,792,458 meters per second, and a nanosecond is a billionth of a second, hence light moves approximately 0.3 meters or around 0.98 feet per nanosecond in one nanosecond. - Measured in nanoseconds • An adapter cardenhances functions of a component of a desktop or server system unit and/or provides connections to peripherals - Sound card and graphics card • An expansion slot is a socket on a desktop or server motherboard that can hold an adapter card. Bus frequency is the external rate data travels outside the microprocessor and is measured in A) Nanoseconds B) Megaseconds C) Megahertz D) Megabytes. PDF Chapter 2: Computer Hardware - testbankbot.com For example you could have DDR RAM (name . The more data and programs that can fit into EEPROM, the less time your computer will spend moving data to and from virtual memory. The answer is the. The speed of a computer is measured in microseconds and nanoseconds. A) milliseconds, 2. When making a decision about what memory to use in your computer, the speed measured in MHz is generally the more important number to consider. CIT 1351-Chapter 2: On the Motherboard Flashcards - Quizlet A gigahertz is cycles per second. Time Conversion Tables from nanoseconds, and quicker, to Light Years Sign in to vote. Since the frequency most clock speed measures is very . Computer memory speed is often represented in nanoseconds, for example, 60ns, 40ns, and 10ns are all different speeds of time it takes for the computer to access the memory. This means that a CPU with a clock speed of 2 gigahertz (GHz) can carry out two thousand million (or two billion) cycles per second. Speed measured in gigahertz 2 GHtz = .5 nanoseconds (Cache = Memory of CPU) Storage The permanent home of all your programs and data. . The more data and programs that can fit into EEPROM, the less time your computer will spend moving data to and from virtual memory. The speed of a computer processor is measured in A) Megabits per second B) Nanoseconds C) Gigabytes D) Gigahertz. So a nanosecond is a billionth of a second. The processing speed of first generation computers was - Brainly.in Currently, RAM is measured in megabytes and gigabytes. Nanosecond is often abbreviated as ns. Speed: A computer is a very fast device. The units of speed are measured in microseconds and nanoseconds. Speed markings on the memory chips may still specific nanoseconds, but in this case in represents the number of nanoseconds between clock cycles. Nowadays, the unit of this speed is 'hertz' which is number of CPU cycles in a second. By Donald MacKenzie May 28, 2021. The higher the clock speed a CPU has, the faster it can process instructions. _____ ANS: F RAM Random Access Memory Random Access Memory (RAM) RAM (Random Access Memory) PTS: 1 REF: 75 5. . How can I measure the speed of code written in Java? (AI algorithms) 3. Characteristics of Computer |authorSTREAM Using centimeters is actually more accurate since light travels exactly 29.9792458 cm in a nanosecond. The easiest timer to use when trying to measure execution times is perhaps QueryPerformanceCounter which you can find out how many "counts/sec" that refers to by calling QueryPerforanceFrequency. Accuracy of Computer Computers not only provide incredible speed, instead, they are also capable of consistently working with accuracy.
