UGC NET Law Unit - VII flashcards — 50 questions with answers

  1. What does the acronym ASCII stand for?

    American Standard Code for Information Interchange.

  2. How many bits does standard (basic) ASCII use to represent each character?

    7 bits.

  3. How many distinct characters can standard 7-bit ASCII represent?

    128 characters (2^7).

  4. How many bits does Extended ASCII use and how many characters can it encode?

    8 bits, encoding 256 characters (2^8).

  5. What is the ASCII code (decimal) for the uppercase letter 'A'?

    65.

  6. What is the ASCII code (decimal) for the lowercase letter 'a'?

    97.

  7. What is the ASCII code (decimal) for the digit character '0'?

    48.

  8. What is the constant decimal difference between an uppercase ASCII letter and its lowercase counterpart?

    32 (lowercase = uppercase + 32).

  9. What decimal ASCII range is occupied by the digit characters '0' through '9'?

    48 to 57.

  10. What kind of characters are represented by ASCII codes 0 to 31?

    Non-printable control characters (e.g., null, tab, carriage return, line feed).

  11. What does the acronym ISCII stand for?

    Indian Script Code for Information Interchange.

  12. How many bits does the ISCII encoding scheme use per character?

    8 bits (a single byte).

  13. Which organisation developed ISCII and in which year was it standardised?

    The Bureau of Indian Standards (BIS); standardised in 1991.

  14. What is the primary purpose of ISCII?

    To encode the characters of Indian-language scripts on computers using a single standard.

  15. In ISCII, what occupies the lower 128 code values (0-127)?

    The standard ASCII characters, making ISCII a superset of ASCII.

  16. How many Indian scripts does ISCII support?

    Ten Brahmi-based Indian scripts (e.g., Devanagari, Bengali, Tamil, Telugu, etc.).

  17. What is stored in the upper 128 code values (128-255) of ISCII?

    The characters of Indian-language scripts.

  18. Most Indian scripts encoded by ISCII are derived from which ancient script?

    The Brahmi script.

  19. What key advantage does ISCII give for typing multiple Indian languages?

    A common keyboard/encoding can be used for all supported Indian scripts because they share the same code positions.

  20. Which modern universal encoding standard has largely replaced ISCII?

    Unicode.

  1. What is the core goal of the Unicode standard?

    To assign a unique number (code point) to every character in every writing system, independent of platform, program or language.

  2. Approximately how many code points does Unicode allow, and what is the upper limit?

    Up to 1,114,112 code points (U+0000 to U+10FFFF).

  3. How do the first 128 Unicode code points relate to ASCII?

    They are identical to ASCII, ensuring backward compatibility.

  4. Name the three main Unicode Transformation Format (encoding) schemes.

    UTF-8, UTF-16 and UTF-32.

  5. How many bytes per character does UTF-8 use?

    A variable length of 1 to 4 bytes per character.

  6. How many bytes per character does UTF-16 use?

    2 bytes for most characters, or 4 bytes (a surrogate pair) for supplementary characters.

  7. What is the standard notation for writing a Unicode code point?

    'U+' followed by the hexadecimal value, e.g., U+0041.

  8. Which body develops and maintains the Unicode standard?

    The Unicode Consortium.

  9. Which Unicode encoding is fully backward-compatible with ASCII and dominant on the web?

    UTF-8.

  10. What is the Unicode code point for the uppercase letter 'A'?

    U+0041 (decimal 65).

  11. What is the difference between primary and secondary storage?

    Primary storage (e.g., RAM) is fast, directly accessible main memory and usually volatile; secondary storage (e.g., HDD/SSD) is slower, permanent, non-volatile bulk storage.

  12. Give an example of volatile memory and state what 'volatile' means.

    RAM; volatile means its contents are lost when power is switched off.

  13. Give two examples of non-volatile storage.

    ROM and Hard Disk Drive (also SSD, flash drives, optical discs).

  14. How many bits make up one byte?

    8 bits.

  15. State the relationship between KB, MB, GB and TB (binary).

    1 KB = 1024 bytes, 1 MB = 1024 KB, 1 GB = 1024 MB, 1 TB = 1024 GB.

  16. What is the main physical difference between an HDD and an SSD?

    An HDD stores data magnetically on spinning platters with moving parts; an SSD uses flash memory with no moving parts, making it faster and more durable.

  17. What is cache memory and where is it located?

    A small, very fast memory placed between the CPU and main RAM that stores frequently used data/instructions to speed up processing.

  18. List the memory hierarchy from fastest to slowest.

    Registers > Cache > Main memory (RAM) > Secondary storage (HDD/SSD/optical).

  19. Give three examples of optical storage media.

    CD, DVD and Blu-ray disc.

  20. State the typical storage capacities of a CD, a DVD and a single-layer Blu-ray disc.

    CD about 700 MB, DVD about 4.7 GB, single-layer Blu-ray about 25 GB.

  21. What is the fastest type of storage in a computer, located inside the CPU?

    Registers.

  22. What is the difference between RAM and ROM?

    RAM is volatile read/write working memory; ROM is non-volatile memory that is permanently written and mainly read (stores firmware/boot instructions).

  23. Define an input device.

    A hardware device that feeds data and instructions from the user into the computer.

  24. Define an output device.

    A hardware device that presents processed data (results) from the computer to the user.

  25. Give four common examples of input devices.

    Keyboard, mouse, scanner and microphone.

  26. Give three common examples of output devices.

    Monitor, printer and speaker.

  27. Name two devices that act as both input and output devices.

    Touchscreen and modem (also network interface card).

  28. What do the acronyms OMR and OCR stand for?

    OMR = Optical Mark Recognition; OCR = Optical Character Recognition.

  29. What does MICR stand for and where is it mainly used?

    Magnetic Ink Character Recognition; used to process cheques in the banking industry.

  30. What is the difference between impact and non-impact printers, with an example of each?

    Impact printers strike the paper through a ribbon (e.g., dot-matrix); non-impact printers print without striking (e.g., inkjet, laser).
