Computer Internet Questions and Answers

Answer: B

Correct answer: 2 and 3

A bridge divides a network into separate collision domains, so stations on either side no longer contend with each other, which gives each segment its own share of the bandwidth. A bridge forwards broadcasts, so it does not divide the broadcast domain - that requires a router.

Answer: C

Correct answer: Insert

A symbol is something added to the document, so the command is on the Insert menu, alongside picture, object and page break.

Answer: B

Correct answer: LAN

Ethernet, token ring and token bus are all local area network technologies, distinguished by how stations gain access to the shared medium: contention in Ethernet, a circulating token in the other two.

Answer: B

Correct answer: 12 pt

The Normal template's default is 12 point Times New Roman in the versions these questions describe; later versions changed both the size and the typeface.

Answer: A

Correct answer: The modem between computers

Routers, firewalls and switches all divide a network into parts and control what passes between them. A modem converts signals for transmission over a line; it does not subnet anything or filter traffic, so it neither separates the LAN nor protects it.

Answer: B

Correct answer: Mega bits per second

LAN speeds are quoted in megabits per second - 10, 100 and 1000 Mbps for the successive generations of Ethernet. Kilobit rates belong to dial-up modems.

Answer: B

Correct answer: Formatting tool bar

Word displays the Standard and Formatting toolbars by default. The Drawing and Forms toolbars have to be switched on.

Answer: C

Correct answer: Mailbox

A mailbox is the account together with the storage that holds its messages. An IP address identifies a machine and an attachment is a file carried with a message.

Answer: C

Correct answer: Modem

Routers, switches and bridges all forward traffic between hosts or segments within a network. A modem converts between digital and analogue signals so that data can cross a telephone line; it adapts the signal rather than making forwarding decisions, which is why it is not counted among the network devices proper.

Answer: C

Correct answer: Star

In a star topology every node has its own link to a central hub or switch, so all traffic passes through that centre. That makes cabling simple and one node's failure harmless, at the cost of depending entirely on the central device.
