It is the speed of your processor, that you need to know. It would be the size of your memory that is important. For both of those things, it is important to know them when you have a particular piece of software to run or work to be done that needs a minimum level of processor speed and memory size to work properly.
It is important that you ask a technitian to do it if you don't know how.
speed compatability maximum memory allowed
No you dont, the most important things are clock speed(example 533Mhz) and timings(example 3-8-4-4) you want to be the same per chip as your memory will always work at the slowest chip speed if this is not matched up evenly. The amount of memory per chip does not matter.
The most important thing to watch is that the mhz speed of the Ram matches the cpu operating freqeuncy. Not matching them can cause erratic behaviour of the CPU
the speed of light is the most important number
yes
When choosing your driving speed, the most important thing to consider is
Pricing, reliability, and speed are considered the three most important aspects.
Around 3000 mega bytes
Speed
Processor registers occupy the top most position in memory hierarchy. They provide high-speed storage space and fast access to data.
the most important in this live....you will know later if you don't know right now.
