Match the Pairs

Draw a line connecting each item on the left to its match on the right.

Left column		Right column
1Student: Read only		AGiving all users full control ignores the idea of access levels. Rights should be set per file or folder to match each role.
2Teacher: Read/Write		BStudents can edit their own marks, which harms integrity. They should only have read only access, or no access.
3No access stops a user from even seeing a folder, which protects confidentiality.		CPayroll folder -> Student: No access
4An administrator has full control, while an ordinary user has fewer rights.		DThe user can open and view the file but cannot change, delete or save edits to it.
5Marks file -> Student: Read/Write		EAdmin: Full control, User: Read only
6Everyone: Full control on every file		FThe user can open the file and also edit, add or delete its contents.

Answer Key

Access levels

Section A: Quick Questions

A — Read only

B — No access

A — They give different users different rights to the same data

A — Read/write

B — An administrator

Section B: Match the Pairs

Student: Read only → The user can open and view the file but cannot change, delete or save edits to it.

Teacher: Read/Write → The user can open the file and also edit, add or delete its contents.

No access stops a user from even seeing a folder, which protects confidentiality. → Payroll folder -> Student: No access

An administrator has full control, while an ordinary user has fewer rights. → Admin: Full control, User: Read only

Marks file -> Student: Read/Write → Students can edit their own marks, which harms integrity. They should only have read only access, or no access.

Everyone: Full control on every file → Giving all users full control ignores the idea of access levels. Rights should be set per file or folder to match each role.

Section C: Definitions

access levels — Settings that give each user different rights to data: no access, read only, read/write or full control. Users only see and change what their role needs, protecting confidentiality and integrity.

Section D: Fill in the Blanks

SET Marks.xls FOR Student TO READONLY

SET Marks.xls FOR Teacher TO READWRITE

SET Payroll FOR Visitor TO NOACCESS

SET Settings FOR Admin TO FULLCONTROL

IF level = READONLY THEN
  OUTPUT "Cannot edit file"
ENDIF

Section E: Spot the Error

D — The branch prints "View only", so it must test for the read-only level. It should be ELSE IF level = "read" THEN. "full" is the administrator level, which can do much more than view.

A — The access level is a text value, so it needs quote marks. It should be staffLevel ← "none". Without quotes, none looks like a variable name.

B — A pupil should only have read-only access to the marks file. Full control would let them change their marks, which breaks integrity. It should be pupilLevel ← "read".

A — An IF statement must end with THEN. The line should be IF role = "admin" THEN. Administrators get full control and ordinary users get read-only access.

B — The string is missing its closing quote mark. It should be level ← "read/write". Every text value must start and end with a quote.
