i have some questions to ask and i'm not sure what website i can go to to ask computer-related
questions. The first question is, can u go from say 128 mb to 512 mb of memory in my cpu? which
one is bigger out of mb, kb, gb, ghz, etc? and are they referring to the same thing and just one
size bigger than the next or does one have absolutely nothing to do with the other? are all cpus
compatible with any monitor and vice versa as well as harddrives, cd-w, cd-rw drives? i'd
appreciated if u could answer my questions if someone else could. thank u. Sam

Hey Sam,

You can easily upgrade your memory (RAM) as long as two things are true... The speed of the memory is allowable on your motherboard, and you have an open bank for a SIMM or DIMM. If you have SIMMs (the short stick with the larger chips), then you need to pair them up in the machine in corresponding banks. The speed is normally on a sticker on the chip(s) already in the machine, and is read as PC100, PC133, etc.

As for the size names. MB, KB, and GB all refer to storage size (inbytes). They are 1000 bytes=1 kilobyte(KB), 1000KB=1 megabyte(MB), and 1000MB=1 gigabyte(GB). RAM is usally in MB, HDD size in GB.

Megahertz and Gigahertz (MHz and GHz) are frequencies used to measure processor speed (a pentium or AMD, that sort of thing). The same rule applies as with KB->MB->GB relationships.

Finally, all IBM compatible machines (Windows machines) use the same 15-pin monitor adapter and are compatible. HDD, CD-ROM, and CD-RW can sometimes vary. Most all today use the IDE standard, and are, thus, interchangable. If by chance, however, you come across a drive that is SCSI instead of IDE, you will need a separate controller card (PCI or ISA buses are used for these). I think that about does it.

Sam,
The above answer is pretty complete (at least, as complete as this limited space allows), but I don't really agree on the monitors.
VGA monitors typically use 15 pins, but not all of them. You may stumble on monitors that require BNC connectors (4 or 5 "cable-TV" style of connectors), or on monitors that require a 9-pin connector. But I admit, those are not as common.

And I wanted to share this link:
http://www.cacr.caltech.edu/~roy/dataquan/
It explains quite comprehendable the different sizes (bit, byte, KiloByte, TeraByte,...)

But really, Squeech deserves that you "accept" his answer.

Jim
