  • A1024
  • B8000
  • C8192
  • D8 388 608
Mark scheme
  • C 8192 (1)
  • The only correct answer is C. The correct answer is 8192.
  • A is not correct because 1024 is the number of bytes in a kibibyte
  • B is not correct because 8000 is the number of bits in 1000 bytes
  • D is not correct because 8 388 608 is the number of bits in a mebibyte
Example answers and how they were marked
Full marks1/1

C 8192

Why: Correct: one kibibyte is 1024 bytes and 1024 × 8 = 8192 bits (1).

No marks0/1

A 1024

Why: Near miss: 1024 is the number of bytes in a kibibyte, not the number of bits (0).

No marks0/1

B 8000

Why: Typical misconception: uses 1000 bytes for a kibibyte, giving 1000 × 8 = 8000 bits (0).

[1 mark]
  • ALAN
  • BPAN
  • CWAN
  • DWLAN
Mark scheme
  • C WAN (1)
  • The only correct answer is C. The correct answer is WAN, which connects networks over a large geographical area.
  • A is not correct because a LAN covers a limited area such as one building or site
  • B is not correct because a PAN connects devices around one person
  • D is not correct because a WLAN is a LAN that uses wireless connections and is still local

Why: Distractor, not a partial-credit answer: each store may have its own LAN, but the network linking stores in different countries is a WAN (0).

No marks0/1

D WLAN

Why: A WLAN is still a local-area network that uses wireless connections and cannot connect stores in different countries (0).
