Question

Match the following list:

	List – I (Codes)		List – II (No. of Bits used)
(a)	Baudot code	(i)	7 bits
(b)	ASCII code	(ii)	5 bits
(c)	EBCDIC code	(iii)	10 digits
(d)	Code 39	(iv)	8 bits

1. (a) – (ii), (b) – (i), (c) – (iv), (d) – (iii)
2. (a) – (i), (b) – (ii), (c) – (iii), (d) – (iv)
3. (a) – (ii), (b) – (i), (c) – (iii), (d) – (iv)
4. (a) – (iv), (b) – (iii), (c) – (ii), (d) – (i)

Answer 1

Correct Answer - Option 1 : (a) – (ii), (b) – (i), (c) – (iv), (d) – (iii)

ASCII Code:

• ASCII stands for American standard code for information interchange.
• Represents 128 English characters as numbers, each character assigned a number from 0 to 127.
• It is a 7-bit code (∵ 2⁷ = 128)

EBCDIC:

• Extended Binary coded Decimal interchange code.
• 8-bit character encoding used for IBM.

From the above two, b → (i), c → (iv).

Baudot Code:

• Binary code which uses crosses and dots.
• Used for teleprinter message and allowed to encode 2⁵ = 32 characters.
• It is a 5-bit code.

Code 39:

• Code 39 defines 43 characters

It uses 10 digits
