How does the input unit contribute to a computer's operation?
Press to flip
It enters raw data into the computer system, allowing it to be processed by the CPU.
Identify the four main units represented in a computer's block diagram.
Input Unit, Central Processing Unit (CPU), Memory Unit, and Output Unit.
How do primary and secondary memory differ in a computer system?
Primary memory (RAM and ROM) stores data temporarily and is faster, while secondary memory provides extra storage (e.g., hard disks).
Explain the function of the Control Unit within the CPU.
It manages and coordinates the operations of the computer by directing how data is processed.
What components are considered part of the hardware in a computer system?
Physical components such as keyboard, monitor, and printer.
Describe the unique characteristics of computers that differentiate them from humans.
Speed, storage, accuracy, diligence, versatility, flexibility, and cost-effectiveness.
Discuss the concept of cost-effectiveness in computers.
Computers reduce paperwork and human effort, ultimately saving costs in various operations.
What are the primary areas of study within computer science?
Theory of computation, algorithms, and design of computers (hardware, software, applications).
Who is known as the 'Father of Computer Science' and why?
Alan Turing, for his significant contributions to the theory of computation.
What are the main types of software and their roles in a computer system?
System Software, which controls hardware resources, and Application Software, which performs specific tasks.
What are some examples of application software, and what functions do they perform?
Word processors, games, and other software designed for specific tasks such as document creation or entertainment.
Distinguish between data and information in the context of computing.
Data is raw, unprocessed facts, whereas information is processed data that is meaningful.
Outline the roles of the ALU in a computer's CPU.
The Arithmetic and Logic Unit performs all arithmetic and logical operations.
What makes a computer versatile and flexible?
Its ability to perform multiple tasks simultaneously and be used across various fields like research and military.
Why is Charles Babbage regarded as the 'Father of Computers'?
He invented the Analytical Engine, an early mechanical general-purpose computer.
