Computer Systems Fundamentals Quiz

CPU Components

• The three main parts of the CPU are: Control Unit, Arithmetic Logic Unit (ALU), and Registers
• The Control Unit retrieves and decodes instructions, generates control signals, and manages data transfer
• The Arithmetic Logic Unit (ALU) performs mathematical and logical operations
• Registers are small amounts of on-chip memory that store data temporarily while it is being processed

Custom Software

• Software developed for specific company requirements is called Custom Software or Tailored Software
• It is designed to meet the unique needs and requirements of a particular organization

Application Software

• Application Software includes programs that perform specific tasks or functions for users
• Examples include: Microsoft Office, Adobe Photoshop, Web browsers, and Games

Input and Output

• The main function of Input and Output in a computer system is to allow users to interact with the computer and view results
• Input devices allow users to enter data, instructions, and commands
• Output devices display the results of processing, such as text, images, and sounds

Registers

• The purpose of Registers in a computer system is to store data temporarily while it is being processed
• Registers are small amounts of on-chip memory that are faster and more efficient than main memory
• They enable the CPU to quickly access and manipulate data during processing
