CPU Components
This CPU component performs arithmetic operations like addition and subtraction.
What is the ALU?
This processing method executes one instruction at a time.
What is serial processing?
This is the main memory used to store programs and data currently in use.
What is RAM?
This bus transfers the actual data between CPU, memory, and devices.
What is the data bus?
This firmware initializes hardware during startup.
What is BIOS?
This part of the CPU fetches and decodes instructions but does not process data.
What is the Control Unit (CU)?
This processing method allows multiple instructions to run at the same time.
What is parallel processing?
This small, fast memory stores frequently used data to speed up processing.
What is cache memory?
This bus carries the memory address of where data should be read from or written to.
What is the address bus?
This component stores BIOS settings and is powered by a small battery.
What is CMOS?
This part of the CPU fetches and decodes instructions but does not process data.
What are registers?
This term describes a single program performing multiple tasks simultaneously.
What is multithreading?
This cache level is the fastest and located inside the CPU core.
What is L1 cache?
This bus carries signals like read/write and clock signals.
What is the control bus?
This modern replacement for BIOS supports faster boot times and larger drives.
What is UEFI?
This type of RAM is used to make CPU registers and cache memory.
What is SRAM?
This term describes the OS running multiple programs at once.
What is multitasking?
This term describes the delay between requesting data and receiving it.
What is latency?
This external interface is commonly used for graphics cards and high-speed SSDs.
What is PCI Express (PCIe)?
This core part of the operating system manages CPU, memory, and I/O devices.
What is the kernel?
Name the CPU register that keeps track of the next instruction to be executed.
What is the Program Counter?
A single physical CPU core to act as two logical cores, enabling it to process multiple threads simultaneously.
What is hyperthreading?
This memory technique uses hard drive space to act as extra RAM.
What is virtual memory?
This interface protocol allows SSDs to take advantage of PCIe lanes for very high speeds.
What is NVMe?
Name the four steps of the CPU machine cycle in the correct order.
What are Fetch, Decode, Execute, and Store?
