Flashcards in Lesson 3 - Types of processor Deck (33)
List four benefits of a CISC processor
- Has more complex hardware
-More compact software code
-Takes more cycles per insutrciton
- Can use less RAM as no need to store intermediate results.
List four benefits of a RISC processor
- Has simplier hardware
-More complicated software code
-Takes one cycle per instruction
-Can use more RAM to handle indermediate results.
What does GPU stand for?
Graphic processing unit.
What is a co-processor
Another processor that is bespoke for another task.
Give one example of a co-processor.
- A gpu
What are the benefits of using a co-procesor
They are highly specialized
- GPUs for example are designed for sipmly operatings, being abel to handle larger data sets.
-They have a parrelel structure.
What is a multicore processor?
- A single chip that contains two or more co processing units.
What is Amdahl's law
Just a law that shows you how the performance of cores is increased and decreased.
What is parrelel processing?
The different processors work together to complete a task
What is an input device?
Any device that can get information form the outside world into a digital form.
Give three examples of input devices.
- Card reader
What is an output device?
Takes data that is stored as a digital form into the outside world that hjumasn can understand.
List two examples of an output device.
What is a storage device?
-Any computer hardware that can store data for a temportary or permanenet period.
Give two examples of internal storage.
Give three examples of external storage.
Give three examples of magnetic storage.
Give two advantages of magnetic storage.
Give two disadvantages of magnetic storage.
- Slow access times.
Give three examples of opitical storage
Give three advantages of Optical storage
Give two disadvantages of optical storage
-Slow access times
-Prone to scratches
Give one example of an ssd.
- Flash drives
Give to advantages of SSD storage.
-Fast access times
Give two disadvantages of SSD storage.
-Limited read/write speeds.
What does RAM stand for?
Random Access Memory
What is RAM used for?
Used to store data programs and that the computer is currently running it is faster than accessing the hard drive/ SSD
What would usually be stored in RAM
-OS - Operating System
Is Ram Volatile?
- Yes it is, meaning that if you want to store the data, the data must be copied back onto the HD, or SSD.
