Little Man Computer memory

A Little Man Computer has 99 memory locations which can each store a number between -999 and 999.

These numbers can be either data (something the program has to use or remember) or instructions (something that tells the CPU what to do)

The small numbers on the left show the memory address (like a street address for houses - it just tells you where to look to find something).

The numbers in the white boxes show the value stored at that memory address.

Memory locations can have a text label, which is a way of describing what the data or instruction means at that location.
