Main Memory

This area of the organisation stores information and instructions. The information or data is stored in binary. This is a number system that is used throughout the Percy Processor organisation.

The main memory area contains many different memory locations. Each location, or place, can store 8 binary digits (bits ) of data. Memory is measured in bytes and 1 byte is equal to 8 bits. A binary digit can only be 1 or 0.

The number system that is used throughout the Percy Processor organisation is called the --> Binary Number System.

Binary as the name suggests is a two state system. The two states can be either on or off. An on state is represented by a 1 and an off state is represented by a 0.

This number system is used by all computer systems and information and instructions have to be represented in binary before the computer can understand them. Click here for binary preview
To find out about binary you must choose Method 1 or Method 2.

Method 1 - if you like reading and following instructions (drill & practice) and are quite logical choose this method by clicking Binary 1

Method 2 - if you like trying things out by yourself (discovery learning) and following fairly simple instructions choose this method by clicking Binary 2

Now try the exercise - binary 1 - then try the ascii investigation.
