Answer:

Where is the program you are running?
- In main memory.
- Running programs are always located in main memory.
- A permanent copy will also be in secondary memory on the hard disk.
Where are the characters you have typed?
- In main memory.
- When you "save" your document, the characters are copied to a file on the hard disk.

Secondary Memory

Secondary memory is where programs and data are kept on a long-term basis. Common secondary storage devices are the hard disk and optical disks.

The hard disk has enormous storage capacity compared to main memory.
The hard disk is usually contained inside the case of a computer.
The hard disk is used for long-term storage of programs and data.
Data and programs on the hard disk are organized into files.
- A file is a section of the disk that has a name.

A hard disk might have a storage capacity of 500 gigabytes (room for about 500 x 10⁹ characters). This is about 100 times the capacity main memory. A hard disk is slow compared to main memory. If the processor interacted with it directly the entire computer system would slow down. The reason for having two types of storage is this contrast:

Primary memory

Secondary memory

Fast
Expensive
Low capacity
Works directly with the processor

Slow
Cheap
Large capacity
Not connected directly to the processor

QUESTION 7:
