What is processor cache memory?
A -
Cache Memory is a type of memory used directly by the ROM instructions that are to be executed
B -
Cache Memory is a type of memory used directly by the RAM instructions that are to be executed
C -
Cache Memory is a type of memory used directly by the processor for storing
sinstructions that are to be executed. It tetches a number of instructions, and while
executing those. It tetches the next batch of instructions.
This speeds up performance as she processor doesnt have to want for the
instructions to be retrieved from the original program source before it can executre.
D -
Cache Memory is a type of memory used directly by the OS instructions that are to be executed

working fine the day before?
A -
Test the power supply
B -
Replace the CMOS battery

4-
What is the main difference between Pentium and AMD processors?
A -
The Intel chipsets use MHz as a speed factor IE "This Pentium 4 chip runs at
3000 MHz" (IE a Pentium 4 3 0)
The AMD chipsets do not use a MegaHertz rating for speed because they believe
doing so would make their chips seem slower than their Intel counterparts.
B -
The ADM chipsets use MHz as a speed factor IE "This AthlonXP chip runs at 3000
MHz"
The Intel chipsets do not use a MegaHertz rating for speed because they believe doing
so would make their chips seem slower than their Intel counterparts.
