CompTIA 1001

What are the 3 major components of a modern computer?

Hardware

Operating System

Applications

What are the 3 stages of the computing process?

Input

Processing

Output

What does the External Data Bus do?

Connects the CPU to peripheral devices

What is the AX register?

Accumulator register, handles math and logic.

AX 16 bit

Eax 32 bit

Rax 64 bit

What is the BX register used for?

To store the base address (pointer) to a programs data or structure.

BX 16 bit

EBX 32 bit

RBX 64 bit

What does the CX register do?

Stores counters

CX 16 bit

ECX 32 bit

RCX 64 bit

What is the DX register used for?

Input/output and extra math help

DX 16 bit

EDX 32 bit

RDX 64 bit

What is a quartz oscillator used for?

Sends an electric pulse down the CLK (Clock) wire setting the computer speed. Oscillator and CPU must be on same speed

Slow oscillator = slow computer

Slow CPU clock speed and high oscillator = overheating

A nibble is how many bits?

4 bits

A byte is how many bits

8 bits

A word is how many bytes

16 bits

A double word is how many bits

32 bits

A paragraph or quad word is how many bits

64 bits

What does the MCC (Memory Controller Chip) do?

Grabs data from RAM and puts it on the EDB (External Data Bus) for the CPU

What is the purpose of the address bus?

To allow the CPU to give commands to the MCC

What are the 4 stages in parallel execution

Fetch - get the data from EDB

Decode - figure out what command to run

Execute - perform the calculation

Write - send the data back onto the EDB

What does (static) SRAM do?

Preloads as many instructions as possible and keeps copies of already ran code (acts as a cache) for the CPU

What is the frontside bus?

The address bus and external data bus connections between the CPU, MCC, and RAM

What is the backside bus?

The connection between the CPU and L2 cache (located on motherboard)

What is the difference between multithreading and multicore processing

Multithreading is when resources are decided between two virtual CPUs

Multicore processing is when a computer has multiple CPUs

Socket - LGA 2011

Platform - Intel

What socket and platform is the R4

Socket - LGA 2066
