Architecture FAQs :
What is Virtual Memory?
Memory is used extending the capability of physical memory. This memory is
simulated by the hard drive.When all the RAM is being used the computer will
swap data to the hard drive and back to give the impression that there is more
What are the five stages in a DLX pipeline?
Fetch Stage Instruction Decode Stage Instruction Execution Stage Memory Stage
What is MESI?
is a Cache Coherency protocol used in multi-processor systems to indicate the
state in which the data in the cache of a particular processor is. It stands of
Modified, Exclusive, Shared and Invalid
What is cache memory?
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.(cache memory is used between the c.p.u and
the ram to access dta fastly)
What is hard disk and what is its purpose?
disk is the secondary storage device, which holds the data in bulk, and it holds
the data on the magnetic medium of the disk.Hard disks have a hard platter that
holds the magnetic medium, the magnetic medium can be easily erased and
rewritten, and a typical desktop machine will have a hard disk with a capacity
of between 10 and 40 gigabytes. Data is stored onto the disk in the form of
What?s the speed and device maximum specs for Firewire?
1394 (Firewire) supports the maximum of 63 connected devices with speeds up to
What?s the difference between L1 and L2 cache?
1 cache is internal to the chip, L2 is external. L1 Cache is of Higher speed
than that of L2 Cache.
What is the difference between primary & secondary storage device?
primary storage device the storage capacity is limited. It has a volatile
memory. In secondary storage device the storage capacity is larger. It is a
nonvolatile memory. Primary devices are: RAM / ROM. Secondary devices are:
Floppy disc / Hard disk.
