Hardware - Processor and Memory
This section discusses the physical arrangement of memory, along with the various types of memory found in a computer system.
The memory of a computer is constructed from microchips. Memory can be thought of as a set of pigeon holes or cells with each one having a unique address. Each pigeon hole can store 8 bits of data.
Older memory chips have 30 pins connecting the memory to the computer. It is more usual to have 72 or 128 pins now.
A computer contains two types of memory, Random Access Memory (RAM) and Read Only Memory (ROM).
