Techopedia Explains PEEK and POKE
The most common uses of PEEK and POKE relate to early computing systems such as eight-bit processors. Here, the memory addresses were limited to a certain eight-bit (256-value) range. A user could issue a PEEK command to look at the contents of a particular memory cell. POKE would effectively change that value.
