Computer Internet Questions and Answers

Answer: C

Correct answer: Linux

Linux is an operating system. Windows, macOS, Android and iOS are others. An operating system sits between the hardware and everything else, managing the processor, memory, storage and devices, and providing the services that applications call on. Without it, every program would have to drive the hardware itself. The distractors are all application software, which runs on top of an operating system: Firefox is a web browser, Photoshop an image editor, Excel a spreadsheet. The distinction between system software and application software is exactly what the question tests. Linux is strictly the kernel; a usable system combines it with utilities and libraries, which is why complete systems are called distributions - Ubuntu, Debian, Fedora, Red Hat. It is free and open-source, which is why it dominates servers, supercomputers and embedded devices, and why Android is built on it.

Answer: D

Correct answer: None of these

Ctrl + R right-aligns the selected paragraph in Word. Refreshing a page is a browser command, and closing a window is Ctrl + W.

Answer: D

Correct answer: A browser

A browser requests pages over HTTP and renders the HTML it receives. A protocol is the set of rules it uses, not the program.

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.
