Download speed from a user’s side, is how long it takes a webpage to load, once requested. The measurement for time it takes to load the page and speed of the page is different for two different web pages on the same Internet connection, so for example having a slow internet connection or having a computer which has a lot stored on it is likely to slow it down maybe causing a webpage to time out, so it is best to get the best connection as possible, even though this cost more but it more likely to give you a much quicker and stronger download speed.
PC Peformance Factors;
Cache Memory is basically Random Access Memory that a CPU can access more quicker than it would regular RAM, the CPU will then use cache memory to store instructions that are required to run programs etc, you will find that a larger cache will operate at a specific and high speed, and are considered to be the core of the CPU. Other caches however will simply differ and may be slow.
Processor Speed, which can be known otherwise as clock speed, is the speed in which the microprocessor executes given intructions. The CPU has a fixed number of ticks in which to execute instructions, so the faster the clock the better as more instructions can then be executed. So for example 2 CPu’s may have the same clock speed much may not perfrom the same as some will have a much faster microprocessor meaning that a single caculation can be performed in one tick, but with technology advancing some microprocessors are not even superscalers which means they can execute more then one instruction per clock cyle.
