Answer Key

Benefit of a network: sharing printers

Section A: Quick Questions

B — The printer is on a network, so many devices can send print jobs to it

A — It saves money and space because the school buys fewer printers

B — Send the print job over the network to the shared printer

A — The print jobs wait in a queue and print one at a time

A — A line of print jobs waiting for the printer

Section B: Match the Pairs

shared printer → One printer on a network that many computers and tablets can use

print queue → A waiting list where print jobs line up and print one at a time

A tablet can send a print job over the network to the shared printer in the library → send(printJob, from: tablet, to: sharedPrinter)

A school saves money and space by buying one printer for 30 computers instead of 30 printers → printers = 1 and computers = 30

Every computer needs its own printer, so a school with 30 computers buys 30 printers. → This ignores the network. A network lets many devices share one printer, which saves money and space.

Two students print at once, so the printer prints both jobs at the same moment. → A printer prints one job at a time. The other job waits in the print queue until its turn.

Section C: Definitions

shared printer — One printer on a network that many computers and tablets can use, so a school does not need a printer for every device. Print jobs wait in a queue and print one at a time.

Section D: Fill in the Blanks

connect(printer, network)

send(tablet, printer)

nextJob = first(queue)

computers = 30
printersNeeded = 1

IF printerBusy THEN addToQueue(job)

Section E: Spot the Error

D — A print queue is first come, first served. The job that waited longest prints first, so it should say 'print first job in queue'.

B — The tablet must send the print job to the shared printer, not to another tablet. It should be 'send job to SchoolPrinter'.

C — With a shared printer the school buys only 1 printer, not one for each computer. The line should be 'cost ← 1 * price'.

B — Sharing means every device connects to the same printer on the network. The line should be 'connect Laptop1 to printer'.

D — The loop was started with WHILE, so it must finish with END WHILE. END IF does not match.
