CPU Flashcards
When installing a CPU what should be done before installing the heat sync onto the CPU
Apply thermal paste. Also known as thermal compound, thermal grease, or by the trademarked name arctic silver
With regard to CPU’s what does ZIF stand for
Zero insertion force. It refers to the type of socket used for the CPU. The CPU will generally be held in place by a lever.
What is the system crystal used for?
Its an oscillating quartz crystal used to produce very accurately timed pulses to drive the CPU.
Why do CPU’s run at a higher speed then the system crystal?
Clock multipliers built into the CPU instruct the CPU to do x number of cycles for every pulse of the system crystal.
1151 is a socket for what manufacture
Intel
What is overclocking
Changes the clock multiplier beyond is factory default
Hyper-threading is what?
Multi core CPU emulation via a pipeline that’s capable of receiving 2 pieces of code at the same time.
What is SRAM
The ram used on a CPU for its cache
Which level of cache is the fastest
Level 1. It runs at the CPU clock speed. L2 is slower and L3 is the slowest.
What is a pipeline stall
A situation where the CPU needs a line of code that isn’t ready.
Which level of cache is the largest
Level 3 (or 2 in cases where the cpu only has 2 level). L1 is always the smallest, L2 is the next largest, and L3 is the largest.
Code loaded into the CPU cache comes from where
RAM
Where is the system cache located
Inside the CPU
Another word for a CPU Family Name is -
Micro-architecture
What does PGA stand for with regard to CPUs
Pin grid array. The CPU will have tiny pins sticking out of it.
What does LGA stand for with regard to CPU’s
Land grid array. The CPU will have small contact pads instead of pins.
The AMA4 socket is made by which manufacture
AMD
The TR4 socket is made by which manufacture
AMD
What is an orientation notch on a CPU
One corner of the CPU will be shaped differently as to allow it to be installed in only one way.
What is a more efficient, quieter, and advanced method of CPU cooling
Liquid cooling
When an instruction is sent to the CPU in a binary pattern, how does the CPU know what instruction the pattern means?
Code book
What is a register
A memory location inside a CPU
What is an external data bus
The set of wires that carry data and instructions between the CPU and RAM
