CPU - Answer- Central Processing Unit, which contains the necessary circuitry to
interpret and execute instructions from specific registers.
Clock + Clock Cycles - Answer- A CPU component which emits electrical control
signals (cycles) at regular intervals via vibrations, synchronising other components.
Each time a cycle is emitted, one instruction is executed, with the rate of emission
determining clock speed in GHz. However, cycle emission generates heat, meaning the
clock can overheat and malfunction if clock speed is continuously increased.
CU - Answer- Control Unit, which fetches instructions from main memory in sequence
by monitoring connected hardware, before decoding and converting them into control
signals.
ALU + Buses - Answer- Arithmetic and Logic Unit, which carries out mathematical and
logical operations. Electrical conductors used to transport control signals, memory
addresses, and raw data, between CPU components, as well as between the CPU and
motherboard's components.
FDE Cycle - Answer- 1-Program counter's held address determines the next instruction
to be executed, and is copied into the MAR.
2-MAR fetches the respective data via the address bus, before it's sent to the MDR via
the data bus. As a result, the PC increments by 1, referencing the execution of the
following instruction.
3-Meanwhile, the instructions within the MDR are loaded into, decoded, and executed
by the CIR, before loading into the ACC. This works in parallel with the ALU to execute
various instructions.
Cache Memory - Answer- Areas of high speed RAM built directly into the CPU, which
decrease processing time by storing recently or frequently used instructions from main
memory. As it grows, it's fetching time increases, meaning it's often split into levels in
ascending distance from the CPU; it's also too expensive to be used as main memory...
