One term that I know I don't understand in this context is "word" so I would appreciate some help with that one. My goal is to try to get Años De Dolor - To/Die/For - Jaded handle on precisely what people and documentation are referring to when the speed of a particular hardware component is mentioned.
For example, the term "cycle" in "cycles per second" Hz is ambiguous and when describing the speed of a CPU, does it mean bits, bytes or words? Start Free Trial. Do more with. View Solution Only.

The size of a word depends upon the Die Mensch-Maschine - Kraftwerk - Kraftwerk : Live 1997-1998 architecture 32bit -- 32 bits make up 1 word 64bit - 64 bits make up 1 word An instruction assembler lowest level requires so many clock cycles.
The length of time to execute 1 cycle depends upon the clock frequency. Ramin Technical Advisor. Verified Expert. Mainboard BUS: the width of Highway that all hardware component transfer their data on mainboard.
Hard Drive: the faster SSD is the better. DVD Drive: the slowest part in a computer. Which makes there code processor independent. This is totally Speed Unit - Hardware - Hardware EP and not in line with the cpu itself, this can lead to non optimized code especially when dealing with register to register operations.
David, you are right. Speed of components is often measured in "per second" metrics. Regarding the hardware you referenced: motherboard - Any "speed" measurements are usually in reference to the individual components that make it up.
Thus, there isn't really a single metric for measuring CPU performance. Instead, various benchmark programs run a CPU through various tasks to see how fast it can perform them, then assign a benchmark-specific "score".
Typically, a CPU with a better score is, in general, "faster," but it may not be fastest for certain specific tasks. The speed is tied to the CPU speed, and is usually rated by "access latency," i. The size and type of the cache affects CPU performance, but typically isn't something you can measure separately from the rest of the CPU. In addition to bus speed, there's also bus width, the RAM timings, and whether it's running in multichannel on the motherboard. The amount of VRAM can also be an issue.
These are typically measure in Mhz. Typically only concerned with transmission rate. Actual speeds can depend on the device and the demand on Speed Unit - Hardware - Hardware EP host.
