Dual-booting
A computer with two operating systems. At startup, a
boot manager program lets the user choose which one
to load. "Multiboot" may refer to a dual boot system or to
one that hosts more than two operating systems. For
example, V Communications' System Commander lets
you install all the operating systems you wish on one PC
and choose which one you want at startup.
Dual booting and multibooting are not the same as a
"virtual machine," although sometimes the terms are
used synonymously. Virtual machines host multiple
operating systems, but can run them all at the same
time.
Dual-booting Q/A
Q: Can you triple boot? Quadruple boot?
Whats the limit?
A: Yes and yes. You are only limited by the
size of your hard drive and the number of
partitions (virtual drive separations that
make the computer treat 1 physical hard
drive as being composed of several parts).

Cache memory, L1 cache, L2 cache
Cache memory is random access memory (RAM) that a
computer microprocessor can access more quickly than
it can access regular RAM. As the microprocessor
processes data, it looks first in the cache memory and if
it finds the data there (from a previous reading of data), it
does not have to do the more time-consuming reading of
data from larger memory
L1 cache - Level 1 cache. A small cache integrated in a
processor that provides quick access to the most
recently used data.
L2 cache - Level 2 cache. L2 cache has the same
purpose as L1 cache, but is usually not integrated into
the processor. L2 cache is traditionally made of SRAM
and in socket 7 and older motherboards was in some
cases upgradeable
