Sample ICDL Computer & Online Essentials Practice Questions

Try these sample questions to test your ICDL Computer & Online Essentials exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 126+ question experience with AI tutoring.

1Which component temporarily holds open applications while the computer is powered on?
A.Random Access Memory (RAM)
B.Solid State Drive (SSD)
C.Optical disc drive
D.Universal Serial Bus (USB) flash drive
Explanation: RAM is volatile memory that stores active program data and instructions while the computer is running. When power is removed, RAM contents are cleared. SSDs and USB drives provide non-volatile storage that retains data after shutdown.
2What is the primary role of an operating system?
A.To manage hardware resources and provide a platform for running application software
B.To connect the computer directly to the Irish national broadband network
C.To store backup copies of personal files on a remote server
D.To replace the need for application programs such as word processors
Explanation: The operating system (OS) coordinates CPU, memory, storage, and peripherals, and provides services that application software relies on. Windows, macOS, and Linux are common desktop operating systems tested in ICDL.
3A barcode scanner registers equipment at a test centre. How is this device classified?
A.Output device
B.Storage device
C.Network device
D.Input device
Explanation: A barcode scanner captures data from physical barcodes and sends it to the computer for processing, which is the defining characteristic of an input device.
4A worker connects a laptop to an external monitor using one cable for HD video and audio. Which port is most appropriate?
A.HDMI
B.RJ-11 telephone port
C.PS/2
D.VGA
Explanation: HDMI (High-Definition Multimedia Interface) carries digital video and audio over a single cable. VGA is video-only analog, PS/2 is for legacy keyboards/mice, and RJ-11 is for telephone lines.
5LibreOffice allows users to view and modify source code under its licence terms. Which licence type applies?
A.Freeware licence with closed source
B.Open source licence
C.Shareware licence
D.Proprietary licence
Explanation: Open source licences permit access to source code and generally allow modification and redistribution under defined conditions. LibreOffice is a well-known open source office suite.
6On a Windows 11 PC, where can a user check the installed Windows edition and installed RAM?
A.Control Panel > Devices and Printers
B.Disk Cleanup utility
C.Task Manager > Startup apps tab
D.Settings > System > About
Explanation: Settings > System > About displays device specifications including processor, installed RAM, and Windows edition/version. This is the standard location referenced in ICDL computer essentials training.
7Which storage type uses flash memory with no moving parts and is common in modern laptops?
A.Hard Disk Drive (HDD)
B.Floppy disk drive
C.Solid State Drive (SSD)
D.Magnetic tape drive
Explanation: SSDs use flash memory chips with no spinning platters, offering faster access and greater shock resistance than traditional HDDs. They are standard in most new laptops deployed in Irish education.
8What is the recommended way to safely remove a USB memory stick from a shared PC?
A.Restart the computer every time before removing USB devices
B.Use 'Safely Remove Hardware' or 'Eject' before physically unplugging the device
C.Pull the USB stick out immediately after closing the file
D.Format the USB stick before each removal
Explanation: Safely ejecting ensures pending write operations complete, reducing the risk of data corruption. ICDL file-management training emphasises proper removal of removable storage.
9Which power state saves open documents to disk before powering off, protecting work if battery power may be lost?
A.Full shutdown
B.Hibernate
C.Sleep (suspend to RAM)
D.Screen saver activation
Explanation: Hibernate saves the contents of RAM to the hard drive and powers off. Sleep keeps RAM powered and resumes faster but uses standby power. Hibernate is safer if battery power may be lost.
10An unresponsive application freezes during an ICDL practice session. What is the recommended first step on Windows?
A.Disable the network adapter permanently
B.Delete the Windows System32 folder
C.Unplug the power cable immediately
D.Open Task Manager and end the unresponsive task
Explanation: Task Manager lets users end a frozen application without restarting the entire computer. This is the standard troubleshooting step taught in ICDL computer essentials.

What is the difference between ECDL and ICDL in Ireland?

ECDL (European Computer Driving Licence) was the original European brand; ICDL (International Certification of Digital Literacy) is the current global name under the ICDL Foundation. Ireland adopted ECDL in 1997; both names may still appear locally, but the syllabus and test format are aligned under ICDL Foundation standards.

Yes. Quality and Qualifications Ireland (QQI) has mapped ICDL certification to the National Framework of Qualifications (NFQ). Candidates can use ICDL modules as exemption components for over 40% of QQI awards, supporting progression from post-primary to further education.

Are these the official ICDL exam questions?

No. These are original OpenExamPrep multiple-choice items with Ireland/ICS context for extra drill. ICDL publishes separate sample tests; live certification tests also include practical tasks not fully replicated here.
