Answer Key

OS function: managing user accounts

Section A: Quick Questions

A — The OS creates, stores and controls accounts so each user logs in and gets their own settings and files

B — An administrator

A — It loads that student's own settings and files

B — To identify the user and check they are allowed to use that account

A — An administrator

Section B: Match the Pairs

Create account: username = "sam_k", password set → The OS sets up a new user account so a person can log in with their own username and password.

Delete account: username = "old_user" → The OS removes a user account, so that person can no longer log in and their access ends.

The OS checks a username and password at login before letting the user in to their own account. → IF username = stored_name AND password = stored_pass THEN open_account()

A standard user has limited rights, while an administrator can change settings and manage other accounts. → IF account_type = "administrator" THEN allow_manage_accounts()

Two students share one account called "student" so their files are kept together → Each user should have their own account. Sharing one account means no separate settings, files or access rights, and no privacy.

Give every user administrator rights so nobody is blocked from anything → Most users should be standard users. Giving all users administrator rights lets anyone change settings, delete accounts or harm the system.

Section C: Definitions

user account management — An OS function that creates, stores and controls user accounts, so each user logs in with a username and password and gets their own settings, files and access rights.

Section D: Fill in the Blanks

OS.createAccount("maya", "Pa55word")

OS.deleteAccount("maya")

IF username = savedUser AND
   password = savedPass THEN
   OS.openDesktop(username)

IF accountType = ADMIN THEN
   allowInstallSoftware()
ENDIF

username = input("Username: ")
OS.loadSettings(username)
OS.openFiles(username)

Section E: Spot the Error

C — The OS must compare the typed password with the password stored for the account, not with the username. It should be IF password = storedPass THEN.

D — The program has just created the account, so it must store the password in it. Deleting the account removes it. Line 4 should be STORE newPassword IN account.

A — The program is removing an old user, so the first step is to delete the account, not create it. It should be DELETE account(oldUser).

B — Only an administrator account should be allowed to install software. The test must check for 'admin', not 'standard'. It should be IF type = 'admin' THEN.

C — Each user gets their own files. The OS must load the files of the user who has just logged in, not those of a previous user. It should be LOAD files OF username.
