Computer Science flashcards for NTS NAT-ICS
23 of 50 cards from the Computer Science deck — real questions with worked answers.
Who is regarded as the 'Father of the Computer' for designing the Analytical Engine?
Charles Babbage.
Who is considered the world's first computer programmer for her work on the Analytical Engine?
Ada Lovelace.
What technology characterized the First Generation (1940s-1950s) of computers?
Vacuum tubes (used for circuitry and magnetic drums for memory).
What technology defined the Second Generation of computers?
Transistors (which replaced vacuum tubes, making computers smaller, faster and more reliable).
What key component characterized the Third Generation of computers?
Integrated Circuits (ICs).
What technology defines the Fourth Generation of computers?
Microprocessors (VLSI - thousands of integrated circuits on a single chip).
What technology is associated with the Fifth Generation of computers?
Artificial Intelligence (AI) and parallel processing / ULSI.
Name the first general-purpose electronic digital computer.
ENIAC (Electronic Numerical Integrator and Computer).
On the basis of operation/data handling, what are the three main types of computers?
Analog, Digital, and Hybrid computers.
What is a hybrid computer?
A computer that combines features of both analog and digital computers (e.g., devices in hospital ICU monitoring).
List the four classifications of computers by size and power, from largest to smallest.
Supercomputer, Mainframe, Minicomputer, and Microcomputer.
Which type of computer is the fastest and most expensive, used for tasks like weather forecasting?
Supercomputer.
What is the difference between hardware and software?
Hardware is the physical, tangible parts of a computer; software is the set of programs/instructions that tell the hardware what to do.
Name the four functional units that make up the basic structure of a computer.
Input unit, Output unit, Memory unit, and the CPU (which contains the ALU and Control Unit).
What are the two main components of the CPU?
The Arithmetic Logic Unit (ALU) and the Control Unit (CU).
What is the function of the ALU?
It performs all arithmetic operations (add, subtract) and logical operations (comparisons, AND/OR).
What is the function of the Control Unit (CU)?
It directs and coordinates all operations of the computer by fetching, decoding and executing instructions.
Give two examples each of input and output devices.
Input: keyboard, mouse (also scanner, microphone). Output: monitor, printer (also speakers).
What is the key difference between RAM and ROM?
RAM is volatile (loses data when power is off) read/write memory; ROM is non-volatile permanent memory that retains data without power.
What is the difference between primary (main) and secondary memory?
Primary memory (RAM/ROM) is fast, directly accessed by the CPU, and volatile; secondary memory (hard disk, USB) is slower, non-volatile permanent storage.
What is cache memory?
A small, very fast memory between the CPU and RAM that stores frequently used data to speed up processing.
What are the two broad categories of software?
System software and Application software.
What is system software? Give an example.
Software that manages and controls computer hardware, providing a platform for applications. Example: an Operating System (Windows, Linux).
Planning Computer Science for NTS NAT-ICS
Computer Science is about 19% of the NTS NAT-ICS syllabus by topic count — 21 of 110 topics, spread over 6 chapters. At roughly 45 minutes per topic plus 12 minutes per sub-topic, a first pass runs to about 15 hours.
The heaviest chapters are Introduction to Computers (4 topics), Number Systems and Data Representation (4 topics), Programming Fundamentals (4 topics) . Front-load those while your energy is high; the short chapters are better revision filler later.
Work top-down: read the chapter, then tick topics off individually rather than marking the whole chapter done. Sub-topics are where silent gaps hide.
