ICDL Online Collaboration cheat sheet

Cloud computing delivers computing services (storage, processing, software) over the internet on a pay-as-you-go or subscription basis, rather than from local hardware.

SaaS (Software as a Service) provides fully managed applications accessed via a browser; the provider handles infrastructure, patching, and updates.

PaaS (Platform as a Service) supplies a development and runtime environment; the customer manages the application code, the provider manages the platform.

IaaS (Infrastructure as a Service) supplies virtualized compute, storage, and networking; the customer manages the operating system and everything above it.

The public cloud is shared infrastructure owned by a provider; the private cloud is dedicated to one organization; a hybrid cloud combines both with orchestration between them.

Real-time collaboration lets multiple users edit the same document simultaneously, with changes synchronized near-instantly and presence indicators showing who is active.

Asynchronous collaboration (comments, mentions, task assignments, version history) lets participants contribute at different times without simultaneous presence.

Version control in cloud tools keeps a revision history so any earlier state can be restored; co-authoring typically autosaves and creates named versions.

Permission roles commonly follow a hierarchy: owner > editor > commenter > viewer; least-privilege means granting the minimum role needed for the task.

Cloud storage syncs a local folder to remote servers; a synced file exists in both places, while a backup is a separate point-in-time copy for recovery.

Share permissions are typically view (read-only), comment, and edit; link sharing can be restricted to specific people, the organization, or anyone with the link.

A shared link's scope determines exposure: 'anyone with the link' is public to holders, while 'specific people' requires authentication or an invitation.

File versioning retains prior copies so a file can be restored after accidental overwrite or deletion; retention period is set by the service or administrator.

A shared folder propagates permissions to its contents; moving a file into or out of a shared folder can change who can access it.

Offline access requires files to be marked available on the device; edits made offline sync when connectivity returns and may create conflict copies.

File size and storage quotas are separate limits: a quota caps total account storage, while a per-file limit caps individual uploads.

Revoking access removes a collaborator's permission but does not delete files they previously downloaded or copied.

Two-factor authentication and link expiration/password protection reduce the risk of unauthorized access to shared storage.

A calendar event has a start and end time, time zone, attendees, location or conferencing link, description, and reminder settings.

Recurrence rules define repeating events (daily, weekly, monthly, yearly) with an end condition: never, after N occurrences, or on a date.

Free/busy lookup shows attendees' availability without revealing event details; it is used to find a common open slot.

An organizer can propose a new time; attendees respond with accept, tentative, or decline, and responses update the organizer's attendee list.

Delegation grants another person permission to view or manage a calendar; calendar sharing can be read-only or allow edits.

Time zone handling: events store an absolute instant plus a zone; changing the display zone shifts shown times but not the underlying instant.

Reminders (notifications) fire a set interval before an event; default reminders can be set per calendar and overridden per event.

A scheduling poll lets a group vote on candidate slots; the organizer confirms the slot and the event is created from the winning option.

Public vs private events: private events show as 'busy' to others, while public events can expose title and details depending on sharing settings.

A web conference typically includes audio, video, screen sharing, chat, and recording; bandwidth and device permissions affect quality.

Host controls include muting participants, managing waiting rooms, admitting or removing attendees, and assigning co-host or presenter roles.

A waiting room holds attendees until the host admits them; it is a control for uninvited or unverified participants.

Screen sharing can share an entire screen, a single application window, or a browser tab; sharing a window limits exposure of unrelated content.

Recording consent requirements vary by jurisdiction and policy; recordings are stored in cloud storage and subject to retention and access rules.

Meeting security features include passwords, waiting rooms, locked meetings, and restricting screen-share or chat to specific roles.

Social collaboration platforms use channels or groups, threads, mentions (@name), reactions, and file attachments to organize discussion.

A thread keeps replies grouped under an original message; replying in-thread reduces noise in the main channel feed.

Presence status (available, busy, away) signals availability; notifications and do-not-disturb settings control interruption.
