A major component of all computers is the memory. Without it, today’s
bigger, better, stronger, faster computers would be nonexistent. Computers
utilize two types of memory, Main and RAM. You can think of main memory as
a box that can hold a single byte of information. So if your computer has
one megabyte of memory, it can hold one million bytes of information.
Today, our focus will be on RAM (Random Access Memory), or read and write
memory. RAM permits you to both read and write data to it. So basically,
RAM needs a steady flow of electricity to contain its contents, meaning
that once the power is turned off, all stored memory will be lost. So in
order to work, RAM needs a steady flow of information or it will forget
what it is holding.
