What is it?
What are cores?
Independent subunits in the CPU each with their own cache memory that increase the efficiency of the system
Data, Address, and Control buses
What is a cache line?
A cache line is the smallest set of data that the CPU cache can receive from the computer memory
In 1824, what was discovered?
Silicon
The environmental impacts of manufacturing CPUs
Extraction of Raw Materials, Material Processing, and Assembly
What are threads?
The smallest unit in a core (virtual version of a cpu core). Allows multiple processes to happen within a single core (multi-threading)
What are buses?
Wires that interconnect the various other components within the CPU.
What is clock speed?
Measures the number of cycles your CPU executes per second, measured in GHz (gigahertz).
What did Nikola Tesla invent in 1903?
Logic Circuits
What type of gas emission is released in the productions of silicon?
CO2
What is cache memory?
Type of RAM in the CPU (fastest memory in computer system).
What is the data bus?
The Data Bus is essential for transferring information between different parts of a computer system. It moves data between the CPU and memory.
What is a cycle?
A “cycle” is the basic unit that measures a CPU’s speed.
What year was Apple Founded?
1976
What is E-Waste Recycling?
Recycled materials are used to manufacture new CPUs
What is speed measured in?
Measured in GHz or MHz
What is the address bus formula?
Number of addresses = 2Address Bus Width
8 bits is also equal to...
1 byte
In 1947, what semiconductor device was invented?
Transistors
What is sustainable sourcing?
Sourcing raw materials in a responsible way to lessen the environmental impact of extraction.
Four factors that affect the price of CPUs
Supply and Demand
Production/Manufacturing Costs
Competition between manufacturers
Research and Development costs
Address Bus
What does it mean when signals are sent in series?
They are sent one after the other, like a line.
The microprocessor was invented in what year?
1971
List at least one of two tech companies that are powering manufacturing processes with renewable energy
Apple and Google
