- When you turn the computer back on it needs to get the basic startup routine from somewhere that is _________ . | non-volatile
- The operating system is _________ but it needs to be loaded into RAM to run. | stored on the hard disk
- The computer has a piece of software called the bootstrap loader. This is a small program that is ____________ . | for loading the operating system
- ROM is ___________, this means you cannot write over the contents once it has been created. | Read Only Memory

Q: Software applications and data are loaded into memory from a hard disk.

So why doesn’t the processor get the instructions & data straight from the disk?
- The read/write speed of a hard disk is much slower than the read/write speed of memory.
- Hard disk drives are not very reliable, especially magnetic drives which have lots of moving parts.
- There might not be enough space on a hard disk to store everything.
- The computer might be using a very slow internet connection.
- A processor is not able to convert the data stored on a hard disk into machine code because it is stored in binary code.
- To reduce the amount of times that a hard disk is used so that it will last for longer.
A: The read/write speed of a hard disk is much slower than the read/write speed of memory.

Q: Which three of the following characteristics are most important when choosing memory or a storage device for a computer?
- what is the maximum read & write access speed?
- is it volatile?
- how much does it cost per MB?
- where can you buy it from?
- is it Windows compatible?
- is the packaging recyclable?
- are the instructions printed in english?
- how much does it weigh?
A: what is the maximum read & write access speed?; is it volatile?; how much does it cost per MB?

Q: If a computer system is to keep lots of programs running smoothly at the same time it needs lots of _______________ .
- main memory
- electricity
- hard disk space
- multi-core processors
- space on the desktop
- high-speed ROM
- high-speed internet access
- hardware devices
A: main memory

Q: Sometimes there just isn’t enough main memory for all the programs that need to run. Computers can be configured so part of the hard disk behaves like main memory. This is called _________ .
- virtual memory
- volatile memory
- a server memory upgrade
- cache memory
- hard disk hyperthreading
- ROM expansion
- upgrading memory
- cache extension management
- hard disk hydrotherapy
A: virtual memory

Q: Decide if the following is true or false:

RAM is the type of memory used in the computer’s main memory. Many people say “RAM” when they mean main memory. 'RAM' is short for Rapid Accessible Memory.

Before a program can run it has to be loaded from the hard disk into RAM so the processor can access the instructions. Any data needed for that program to run is also loaded into RAM while the program is running. The main purpose of RAM is to act as a permanent storage for programs and data, not just for the duration of that program. RAM is non-volatile, meaning that when the power is switched off the contents of memory are saved.
- True
- False
A: False
