A typical computer¶

Let's have another simple quiz.

A quiz about basic computer operation (0.5p)¶

Which of the following statements are true? You have only 5 attempts to answer, so please, think carefully your answers.

A minimal computer has only a CPU, a memory and a bus to communicate both.

CPU's control unit synchronizes the ALU operations with the rest of the system

The I/O bus connects CPU and RAM

The address bus width is the same as the CPU word length

A hierarchy of caches is conceptually placed between CPU and RAM

When reading from RAM, the CPU places content to the data bus

An interrupt could be a signal from a peripheral device

Modern PCs and laptops have a wordlenght of 64 bits, RP2040 (Raspberry Pi Pico) microcontroller has 32 bits, while the ATMEGA328 (Old arduino) has a word length of only 8 bits.

If my address bus has 16 lines, I can number my memory position from 0 to 65535
