Grade 11 Theory II — Virtual Memory, Translators & LAN Architecture

Question 1

What is paging?

Question 2

What is swapping?

Question 3

Why does heavy reliance on virtual memory (excessive paging/'thrashing') slow a system down?

Question 4

Which programming language type is closer to machine code — hardware-specific, fast, but hard for humans to read/write?

Question 5

Why is Java described as using a 'two-stage' compilation approach?

Question 6

When would you recommend using an interpreter over a compiler?

Question 7

What is attenuation, as a weakness of bounded (wired) connection media?

Question 8

What is 'cross talk'?

Question 9

In a STAR network topology, what happens if the central device (e.g. the switch) fails?

Question 10

Which topology has every device connected directly to every other device, making it very reliable but expensive to cable?

Question 11

What does a switch use to forward data only to the intended device on a LAN?

Question 12

What is the purpose of DHCP?

Question 13

What is the purpose of DNS?

Question 14

Why was IPv6 created?

Question 15

What is a payload, in the context of a data packet/frame?

Question 16

Which WLAN device lets wireless devices join an existing wired network?

Question 17

Which WAN device connects two different types of networks, translating between different protocols if needed?

Question 18

Why does streaming a live sports match typically use UDP rather than TCP?

Question 19 — Match the columns

Match each network topology in Column A to its key trait in Column B.

Question 20 — Match the columns

Match each protocol in Column A to its purpose in Column B.
