The first one is a good example of multi-threading because the CPU has to execute different tasks within the same programme.

In the second example, the spreadsheet is a program and the calculator is another program and “jumping” or “switching” between two programs is called multi-tasking.

Yes. A computer with a dual core processor can easily perform

CPU. This is called multi-processing. Let me explain…

Is the word “multi” used in all the terms because more than one task is processed or executed?

Correct!

• Multi-tasking: more than one programme is executed.

• Multi-threading: more than one thread is executed.

• Multi-processing: more than one processor is executing programmes and/or threads.

When the CPU has to execute a thread, it first has to load the registers with the

This process is repeated every time the CPU swaps between threads, in other words when it’s implementing multi-

threading.

Intel processors that implement hyper-threading have an extra set of registers so that the data

does not need to be loaded into the same set of registers and can be accessed immediately by

the other thread.

This saves a lot of time and the operating system is “fooled” into believing that there is a second processor core when there isn’t actually one.

A processing technique where “time-slices” are allocated to several applications and processing switches between them giving the impression that all the applications are running at the same time.

A processing technique where threads share the use of one CPU by simulating two CPU execution units. This “fools” the operating system into believing that there are two CPUs.

A processing technique where more than one program or thread executes at the same time on different CPUs or CPU cores

A processing technique where time-slices are allocated to active threads and processing switches between these so fast it appears that an application is doing several things simultaneously.CHECK

This is a definition of multi-tasking - the computer switches between programs giving each one a “slice” of the CPU’s processing time.A processing technique where threads share the use of one CPU by simulating two CPU execution units. This “fools” the operating system into believing that there are two CPUs.

This is a definition of hyper-threading and it happens when a computer has an extra set of registers/execution units into which it can load the data required for a particular thread. The result is that the CPU can execute threads much quicker.A processing technique where more than one program or thread executes at the same time on different CPUs or CPU cores.

This is a definition of multi-processing - the computer can only do multi-processing if it has more than one CPU.A processing technique where time-slices are allocated to active threads and processing switches between these so fast it appears that an application is doing several things simultaneously.

This is a definition of multi-threading and it happens when parts of a program are broken into “threads” and the CPU switches between these threads, giving each one a “slice” of its processing time.

1. Multi-tasking is implemented by means of more than one CPU.

2. Hyper-threading simulates multiple CPU cores so that a single core CPU is able to process threads more efficiently.

3. Multi-processing gives the appearance that more than one task is being executed at a time.

4. Multi-processing and multi-tasking are primarily implemented by means of time-slices.

5. Multi-threading and multi-processing can be implemented at the same time in a quad core CPU.

6. Multi-tasking results in more than one task and/or thread being executed at the same time.

This statement is FALSE – With multi-tasking, you have one CPU that switches between different execution tasks. Multi-processing is implemented by means of multiple CPU cores.

This statement is FALSE – Multi-processing is when multiple processing cores are executing tasks and threads at the same time.This statement is FALSE – Multi-

processing is implemented by means of more than one processing core performing tasks at the same time.

This statement is FALSE – Multi-tasking is the result of more than one task being executed at the same time. When more than one thread is being executed, we call it multi-threading.
