10 Questions
What are the four basic operations (machine cycle) managed by the control unit?
Fetch, Decode, Execute, Write-back (Store)
How is processor speed measured and what does it control?
Processor speed is measured in megahertz (MHz) or gigahertz (GHz), and it controls how fast instructions are executed and synchronizes all the various computer components.
What is the latest trend in processors, and how many processor cores can they have?
The latest trend is multi-core processors, which can have two, three, or four processor cores on a single chip.
What are the three main types of bus and their respective functions?
The three main bus types are address buses (setting memory address), data buses (exchanging data), and control buses (transferring command codes and status signals).
What are the two types of main memory in the system unit, and provide examples of each?
The two types of main memory are Volatile memory (e.g., RAM) and Nonvolatile memory (e.g., ROM, Flash memory, CMOS).
What are the main functions of the central processing unit (CPU)?
The main functions of the CPU are to control all the computer's functions and to coordinate its functions with other computer units.
What are the two types of operations performed by the Arithmetic Logic Unit (ALU)?
The Arithmetic Logic Unit (ALU) performs arithmetic and logical operations.
Name two main processor manufacturers and their popular processor names.
The main processor manufacturers are AMD and Intel. AMD has processors called Athlon and Turion (mobile), while Intel has Pentium and Centrino (mobile) processors.
What is the function of the Control Unit in the CPU?
The Control Unit directs the movement of instructions and signals between information, memory, and the arithmetic logic unit. It also directs control signals between the CPU and output devices.
What are integrated circuits (ICs) and where are they found in the CPU?
Integrated circuits (ICs) are made up of millions of microscopic parts connected together on a single silicon chip. They are found in the central processing unit (CPU).
Test your knowledge about the central processing unit (CPU) and microprocessor, which are the 'brains' of the computer made up of integrated circuits (ICs) controlling all computer functions. Learn about main processor manufacturers like AMD and Intel.
