1. Volatile, Non Volatile, RAM, ROM

​ (a)   memory is a key component of a computer system. Its function is to hold data and programs that are currently in use.

• Primary
• Secondary
• Tertiary
• Hard Drive

​ (a)   is the component of the computer that holds data, programs and ​ (b)   that are currently in use.

• Memory
• instructions
• Storage
• Binary
• Laurus
• texts
• emails
• pandas

Primary memory is built inside the computer. As a result, ​ (a)   can be ​ (b)   primary memory extremely quickly. This gives the processor fast access to the ​ (c)   and instructions that the primary memory holds.

• data
• read from and written to
• read from
• written to
• deleted from
• compressed in
• moved to
• music
• programs

There are two types of primary memory:

​ (a)   (ROM)

​ (b)   (RAM)

• read-only memory
• random access memory

Primary memory is comparatively limited in size compared to secondary storage. In a modern computer, primary memory is often around 4 ​ (a)   .

• GB
• MB
• KB
• Bytes
• PB
• TB
• Bits

​ (a)   can be read from, but not written to. This makes ​ (b)   ideal for storing instructions and data that are needed for the computer to run. These instructions and data are usually programmed by the computer's manufacturer and cannot be overwritten.

• ROM
• RAM
• Cache
• Secondary Memory

The ​ (a)   is an example of a program that is stored in ​ (b)   . It checks that the hardware is functioning correctly, then runs a second program known as the bootstrap program that loads the computer's ​ (c)   from the hard drive into the ​ (d)   .

• BIOS (Basic Input Output System)
• ROM
• operating system
• RAM
• cache

Random access memory (RAM) is ​ (a)   ​ (b)   ​ (c)   .

• volatile
• primary
• memory
• non-volatile
• secondary
• tertiary
• storage

The more ​ (a)   a computer has, the more data and programs it can hold simultaneously. ​ (b)   can also be upgraded easily, unlike other types of primary memory.

• RAM
• ROM

Virtual memory is the use of ​ (a)   ​ (b)   as additional ​ (c)   ​ (d)   .
