Pregunta 7
Pregunta
The [blank_start]Northbridge[blank_end] is a fast chip that allows the CPU to communicate with [blank_start]RAM[blank_end] and the graphics card. As graphics takes a lot of processing, there is typically a [blank_start]Graphics Processing Unit[blank_end] [GPU] on the graphics card. They get hot, so they have a [blank_start]heat sink[blank_end] or fan to reduce temperature.
The Northbridge also communicated with the Southbridge. The Southbridge communicates with Input/Output devices, the [blank_start]Basic Input/Output System[blank_end] [BIOS] and storage devices.

Pregunta 8
Pregunta
RAM is... Select three options:
Respuesta
-
Volatile: loses all of its data when power is lost.
-
Primary storage: can be directly accessed by the CPU.
-
Non-volatile: will not lose any data when power is lost.
-
Connected to the Northbridge.
-
Connected to the Southbridge.
-
The same as ROM.
Pregunta 9
Pregunta
Secondary storage is devices such as USB sticks, or hard drives. Each use different types of memory.
Hard drives use Magnetism, and USB sticks use Solid State Memory. The other type of memory is Optical and is commonly used on disks.

Pregunta 11
Pregunta
The [blank_start]Fetch-Decode-Execeute[blank_end] cycle [also known as the Fetch-Execute cycle] is a process that happens within the CPU. It f[blank_start]etches[blank_end] the next [blank_start]instruction[blank_end], decodes it and then executes it.

Pregunta 12
Pregunta
The CPU contains:
Respuesta
-
Two Level 1s and one Level 2 Cache: a memory similar to RAM. It is faster and more expensive. Level 1 cache only holds a little bit of data, while Level 2 stores more.
-
Control Unit [CU]: it is responsible for coordinating timing and data flow in the processor.
-
Arithmetic Logic Unit [ALU]: responsible for arithmetic and logic operations.
-
Registers: there are many types of registers within the CPU. They're small areas where binary digits are read and written on the CPU.
-
RAM: random access memory
-
ROM: read only memory. Holds the code to start up the computer
Pregunta 13
Pregunta
Types of registers:
(a) Accumulator: temporary [blank_start]storage[blank_end] for ALU results.
(b) Program Counter: stores memory address of the next function. Adds [blank_start]1[blank_end] to it, after each F-D-C cycle.
(c) Instruction Register: current instruction is stored in [blank_start]binary[blank_end].
(d) Memory Address Register: stores memory address of [blank_start]current[blank_end] instruction.
(e) Memory [blank_start]Data[blank_end] Register: stores data that was read or written to memory.

Pregunta 14
Pregunta
What are the paths that each type of bus can take?
Respuesta
-
Bus: to another county. Address Bus: one way, requests data from an address in memory. Data Bus: both directions, both read and written to memory.
-
Bus: one part of the CPU or computer to another. Address Bus: one way, requests data from an address in memory. Data Bus: both directions, both read and written to memory.
-
Bus: one direction from one part of the CPU or computer to another. Address Bus: to a chosen address. Data Bus: both directions, both read and written to memory.
