Hi, Robert, welcome to BC.

PCS MEMORY BOARD
I will like to buy the above items but will like to know if these are the memories we put in a computer?

Words can be misunderstood, it is good you ask your question.

Computers have been made for many years.
Older ones are different than newer ones.
In this century most all are standard types.
1990-1999 ones have more differences.

Memory "cards" or "sticks of RAM" mean the same thing. Random Access Memory circuit cards of a special shape, made to fit that kind of long, rectangular slot that is part of a bigger circuit board. The big circuit board is called the motherboard or mainboard.

The mainboard will determine what RAM (memory cards) will fit. Usually referred by the number of copper "pin" connections are lined up on one side.

One more way computer memory is named has to do with "speed".
Faster usually means newer, and again the mainboard limits the speed.

Finally, the amount or size of the memory is part of the important definition of any kind of computer memory.

So, you must know that memory sold for one computer might NOT work on another.

The words "PCS MEMORY BOARD" tells me that we might be describing a different thing.

Bigger computers are called "mainframes". They are not PC (personal computer) the way we know them. A mainframe might have a "board" that can use memory cards... and that board then might plug into one or more 'processors" that become the big computer. The word board is almost always said to describe
large circuit boards thatsmaller cards fit into.

PC is meant to be a way of describing a small computer that is built like IBM-compatible computers, having one processor on the mainboard I mentioned earlier.

So, be careful of what you buy. I think you need to share more information with us
to make sure it is what you want.

"These can be used for 256MB, 512 MB and 1 GB Memory Sticks
NOTE:It will be necessary to match match all the part numbers with
manufacturers to determine compatibility with each size."

I read this as not memory "cards" but a board that memory cards will fit into.

Memory cards have been made in these sizes (within the last ten years):

32MB
64MB
128MB
256MB
512MB
1024MB (1 GB)

they will have "speeds" of

pc66
pc100
pc133

additionally they will be of a "type"

some examples are below, first word is maker, then size, type & more exact details:

CORSAIR 1GB (2 x 512MB) 184-Pin DDR SDRAM Dual - Retail

* DDR 400 (PC 3200)
* Cas Latency 2.5
* Unbuffered

CRUCIAL 512MB 240-Pin DDR2 SDRAM System Memory - Retail

* DDR2 667 (PC2 5300)
* Cas Latency 4
* Unbuffered

MUSHKIN 256MB 184-Pin DDR SDRAM System Memory - Retail

CORSAIR 128MB 168-Pin SDRAM Unbuffered PC 100 System Memory - Retail

KINGSTON ValueRAM 128MB 168-Pin SDRAM PC 133 Unbuffered System Memory Model KVR133X64C3/128 - OEM

each is very different.
You can find these at a computer parts seller online store

So many types, sizes & speeds. You need to know what is correct for you.

Tell us more of what you want to buy.
