Motherboard
Fatherboard
What is the Von Neumann architecture?
Computer programs ,data and windows format exchange programs are using are stored in the same memory
Computer programs but not the data the programs are using are stored in the same memory
Computer programs and the data the programs are using are stored in the same memory
The CPU operates by repeating three operations:
Fetch – Decipher – Execute
Fetch – Decode – Execute
Fetch – Decrypt – Execute
Fetch – Decrypt – Examine
What does the ALU stand for?
Arithmetic Logic Unit
Arranging Logic Unit
Arithmetic Language Unit
What does the ALU do?
where the actual calculations are done
where the actual processing is done
Which of these is not a CPU registry
PC
MAR
MDR
MCR
What is the difference bewteen the MAR and MDR
The MAR holds the memory address of the current instruction, and then the data that it uses, so that these can be fetched from memory, but MDR holds the instruction, then the data.
The MAR holds the memory instruction and then the data that it uses, so that these can be fetched from memory, but MDR holds the memory address , then the data.
What is the purpose of the CPU?
To fetch and execute instructions stored in CU
To fetch and execute instructions stored in memory
•What is a register?
•A special fast memory location in the CPU
•A special fast memory location in the GPU
•A special fast processor location in the CPU
Select the four special registers in the CPU that we need to know
•PC, MAR, MDR, Accumulator
•PC, MAR, MDR, ACR
•PC, MAR, MDR, ALC
The Arithmetic Logic Unit (ALU) peforms these main actions
Arithmetic operations
•addition, subtraction, multiplication, division
Logical operations
•comparing one data item to another: is it smaller than, greater than or equal to

Ray Tracing
Some chips have CU to help with reflective calculations
What does the control Unit do in a CPU
•Controls and monitors hardware attached to the system
•Controls input and output of data
•Controls the flow of data within the CPU
•Controls and monitors hardware attached to the system
•Controls input and output of data
•Controls the flow of data within the CPU
•Controls the export of data within the GPU
•Controls and monitors hardware attached to the system
•Controls input and output of data
•Controls the export of data within the GPU (When integrated)
What affects CPU performance?
Clock speed
Processor cores
Type and size of memory
Dock Speed
Which of these describe Clock Speed
Everything in a computer happens on the pulse of the internal clock .Therefore, the faster the clock speed, the faster the instructions are processed
Everything in a computer happens at a certain speed. The number of cores affects the speed, allowing the CPU to 'stack' the amount.
What is a Multi-core processor?
A Multi-core processor has two or more processors in the same integrated circuit, linked together
A Multi-core processor has two or more processors within a larger CPU linked together
What is Cache Memory?
•Cache is a small amount of very fast, expensive memory in the RAM
Cache is a small amount of very fast, expensive memory in the CPU
•Cache is a small amount of very fast, expensive memory in the GPU
Generally, which is quicker, RAM or Cache Memory ?
RAM
Cache
True or False, there are different levels of Cache.
True
False
What is an Embedded computers?
An embedded computer is a single microprocessor that includes RAM, ROM and a CPU
An embedded computer is a single microprocessor that includes only the CPU
An embedded computer is a single microprocessor that includes RAM, ROM , CPU , ALR and the graphics processor.
What does RAM do?
Extra temporary memory
Extra permanent memory
Read Action Memory , which means it only is used if the cache is full
What is ROM?
Read Offer Memory
Read Online Memory
Read Only Memory
What is Virtual Memory?
•Virtual memory is part of the hard drive used as an extension to RAM
•Virtual memory is part of the CPU used as an extension to RAM
•Virtual memory is part of the External Memory used as an extension to RAM
What is known as Main Memory?
RAM
ROM
ROC
Rik
Secondary Storage is the hard drive. It is non-volatile . What does this mean?
•it keeps its content when the power is switched off
•it loses its content when the power is switched off
Tick the three storage types
Magnetic
Optical
Solid State
Liquid State
Rotary State
How does a HDD work?
Uses flash memory to store information. Slow read/write speeds. No mechanical or moving parts
Uses Magnetic memory to store information. Slow read/write speeds. No mechanical or moving parts
Uses a metal disk that spins to store information. Magnetic material is on the disc. Slow read/write speeds. Mechanical moving parts
How does an SSD work?
Uses Flash memory to store data. slow read/write speeds. No mechanical or moving parts
Uses Optical memory to store data. Fast read/write speeds. No Mechanical or moving parts
Uses Flash memory to store data. Fast read/write speeds. mechanical moving parts
What is Optical Storage
burning indents onto a disc, that is read while it spins. Uses a laser.
uses Flash memory, fast read/write speeds. No moving parts.
