Which of the following statements is correct?

Correct option is D

The correct answer is (D) ASCII represents characters as numerical codes.

Explanation:

• ASCII (American Standard Code for Information Interchange) represents characters (letters, numbers, symbols) as numerical codes.
• Each character in ASCII is assigned a unique number between 0 and 127, allowing computers and devices to exchange text-based information.
• ASCII is a widely used encoding standard for representing text in computers and communication equipment.

Information Booster:

• ASCII has a range of 128 characters, including uppercase and lowercase letters, digits, punctuation marks, and control characters.
• The extended version of ASCII uses 256 codes, providing more characters, including symbols for other languages.

Additional Knowledge:

• Option A: ASCII is primarily used for high-speed data transmission networks.
• Incorrect. ASCII is used for text encoding, not specifically for high-speed data transmission. High-speed data transmission uses protocols like TCP/IP or Ethernet.
• Option B: LAN supports networking over large geographic areas.
• Incorrect. LAN (Local Area Network) typically supports networking within a limited geographic area, like a building or campus. WAN (Wide Area Network) covers larger areas.
• Option C: CD is a volatile storage medium.
• Incorrect. A CD (Compact Disc) is a non-volatile storage medium, meaning it retains data even when power is turned off. Volatile storage refers to memory like RAM, which loses data when the power is off.
