5web_server.ip = DYNAMIC		EThe phone is given an IP address automatically by the network, so no manual set-up is needed.
6phone.ip = STATIC # every phone		FSetting a static IP on every phone means lots of manual set-up. Dynamic is better for phones because it needs less set-up work.

Answer Key

Choosing static or dynamic IP for a device

Section A: Quick Questions

B — Static IP address

A — Static, because the printer must always be found at the same address

A — Dynamic IP address

B — Dynamic needs less set-up work because the router assigns the address automatically

A — Static, because other devices must always be able to find it

Section B: Match the Pairs

web_server.ip = STATIC → The web server keeps one fixed IP address so other devices can always find it.

phone.ip = DYNAMIC → The phone is given an IP address automatically by the network, so no manual set-up is needed.

A network printer should use a static IP so that laptops can always find it to print. → printer.ip = STATIC

A home laptop should use a dynamic IP because it needs less set-up work. → laptop.ip = DYNAMIC

web_server.ip = DYNAMIC → A web server needs to be found at the same address every time. A dynamic IP can change, so users might not find it. It should be STATIC.

phone.ip = STATIC # every phone → Setting a static IP on every phone means lots of manual set-up. Dynamic is better for phones because it needs less set-up work.

Section C: Definitions

static or dynamic IP — Use static for devices others must always find, like web servers and printers; use dynamic for phones and laptops because it needs less set-up work.

Section D: Fill in the Blanks

device ← "web server"
ipType ← "static"

device ← "laptop"
ipType ← "dynamic"

IF device = "printer" THEN
  ipType ← "static"
ENDIF

IF device = "phone" THEN
  ipType ← "dynamic"
ENDIF

OUTPUT "Use dynamic because
 it needs less set-up"

Section E: Spot the Error

C — A web server must always be found at the same address, so it needs a static IP address. Line 3 should be ipType ← "static".

B — A home laptop is an ordinary device, so dynamic is best because it needs less set-up work. Line 2 should be ipType ← "dynamic".

D — A printer is shared, so others must always find it at the same address. It needs a static IP, not dynamic. Line 4 should be ipType ← "static".

A — The program gives a dynamic IP address, which suits ordinary devices like phones. A web server needs a static address, so line 1 should test for "phone".

A — The text "web server" is a string, so it must be written in quotation marks. Line 1 should be device ← "web server".
