# How big is the capacity of a standard memory cell that the pointer is linking to?

Often programming language lectures and references have an illustration of computer memory as an array composed of individual cells. Each cell has an address, which is effectively the pointer and can be used to access it. I learned that 32 bit systems will have 4 byte pointers and then got curious what the (standard) capacity of those cells (they are pointing to) was. The most discrete unit of memory is a Memory Cell, but with 1 bit capacity, this does not really fit the bill.

• Please edit the question to provide more context and background to help us understand what you are trying to learn. Where did you encounter this? What does "standard memory cell" mean for you? You write "the pointer" - what pointer is that?

• In many programming intro courses etc, they will have this illustration of memory as an array composed of individual cells. Each cell has an address, which is effectively the pointer and can be used to access it. I learned that 32 bit systems will have 4 byte pointers and then got curious what the capacity of those cells was. Search online did not yield immediate results. Jan 28, 2020 at 8:19
• Rather than leaving clarifications in the comments, please edit the question to make it read well for someone who encounters it for the first time and contain all relevant information, so people don't need to read the comments to understand what you're asking. Thank you.

What your favorite language does above the machine's intrincacies, ask them. Often they will refuse to handle pointers that aren't aligned at some "machine natural boundary", like the size of a C double, 8 bytes. Even on machines that have no penalty attached to non-aligned address acces.
