Computer Knowledge flashcards for LIC AAO
23 of 51 cards from the Computer Knowledge deck — real questions with worked answers.
Who is regarded as the Father of the Computer, credited with designing the Analytical Engine?
Charles Babbage.
Which generation of computers used vacuum tubes as their main electronic component?
The First Generation (1940s-1956).
What primary technology defined Second Generation computers?
Transistors, which replaced vacuum tubes.
What component characterized Third Generation computers?
Integrated Circuits (ICs).
Which technology defines Fourth Generation computers?
Microprocessors (VLSI - Very Large Scale Integration).
Fifth Generation computers are based on which emerging technology?
Artificial Intelligence (AI) and ULSI / parallel processing.
What is the difference between hardware and software?
Hardware is the physical, tangible parts of a computer; software is the set of programs and instructions that run on it.
What are the two main categories of software?
System software (e.g., operating systems) and application software (e.g., MS Word).
What is firmware?
Software permanently stored in hardware (ROM), such as BIOS, that controls device functions at startup.
What is the function of the CPU and what are its main components?
The CPU (Central Processing Unit) processes instructions; its main components are the ALU (Arithmetic Logic Unit), the Control Unit (CU), and registers.
Name three common input devices and three common output devices.
Input: keyboard, mouse, scanner. Output: monitor, printer, speakers.
What is the difference between RAM and ROM?
RAM is volatile, read/write temporary working memory; ROM is non-volatile, permanent read-only memory retained when power is off.
What are the two main types of RAM?
SRAM (Static RAM) and DRAM (Dynamic RAM).
What is cache memory and why is it used?
A small, very fast memory between the CPU and RAM that stores frequently used data to speed up processing.
Order these storage units from smallest to largest: GB, KB, TB, MB, Byte.
Byte < KB < MB < GB < TB.
How many bits are in one byte, and how many bytes in one kilobyte?
1 byte = 8 bits; 1 KB = 1024 bytes.
What is the difference between primary memory and secondary memory?
Primary memory (RAM/ROM) is directly accessible by the CPU and mostly volatile; secondary memory (HDD, SSD, CD) is non-volatile permanent storage not directly accessed by the CPU.
What is the base (radix) of the binary, octal, decimal, and hexadecimal number systems?
Binary = 2, Octal = 8, Decimal = 10, Hexadecimal = 16.
What is the decimal equivalent of the binary number 1010?
10.
What digits/symbols are used in the hexadecimal number system?
0-9 and A, B, C, D, E, F (where A=10 to F=15).
What is ASCII and what is it used for?
American Standard Code for Information Interchange; a coding scheme that represents characters as numbers (standard ASCII uses 7 bits).
What is the function of an operating system?
It manages hardware and software resources, controls memory, processes, files, and I/O, and provides an interface between the user and the computer.
Give two examples each of a GUI-based and a command-line operating system.
GUI: Windows, macOS. Command-line: MS-DOS, UNIX/Linux (shell).
Planning Computer Knowledge for LIC AAO
Computer Knowledge is about 11% of the LIC AAO syllabus by topic count — 12 of 108 topics, spread over 3 chapters. At roughly 45 minutes per topic plus 12 minutes per sub-topic, a first pass runs to about 10 hours.
The heaviest chapters are Computer Fundamentals (4 topics), Operating Systems and MS Office (4 topics), Internet, Networking and Security (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.
