What this dot point is asking
WJEC asks you to describe the main ways people and organisations communicate digitally, and to choose the most suitable method for a given situation with reasons. The exam form is a "recommend and justify" question, so you need a clear idea of what each method is best for, plus its benefits and drawbacks.
Email is the standard for formal, recorded communication.
Instant messaging and VoIP
These methods are for quicker, more immediate contact.
Video conferencing and social media
These support live group contact and wider sharing.
Choosing the right method
The exam rewards matching the method to the need.
Benefits and drawbacks
Across the methods, common benefits are speed, low cost, communication over any distance, and reaching many people at once. Common drawbacks are the need for an internet connection and devices, security and privacy risks, the chance of misunderstanding without tone or body language in text, and the loss of face-to-face contact. A good evaluation weighs these against the specific situation.
Synchronous and asynchronous communication
A useful way to compare the methods is whether they happen live or not. Synchronous communication happens in real time, with both people present at once, such as a video conference, a VoIP call or live instant messaging; it suits urgent matters and discussion, but everyone has to be available at the same time. Asynchronous communication does not require both people at once: a message is sent and read later, such as email or a social media post; it suits people in different time zones or with busy schedules, and it leaves a record, but replies are slower. Naming whether a method is synchronous or asynchronous, and matching that to the situation (for example asynchronous email for a contract, synchronous video for a meeting), adds precision to a recommend-and-justify answer.
Why this matters
Digital communication underpins how modern work, learning and social life happen, and choosing the right method is a genuinely useful skill: using email where instant messaging is too casual, or video conferencing where a phone call is not enough. This dot point also connects to the rest of the topic, the reliability of what you read online and the effects of social networking, and to the security topic, since communication channels are common targets for attacks such as phishing.
Exam-style practice questions
Practice questions written in the style of WJEC exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
WJEC-style4 marksA company with staff working in different countries needs to hold regular team meetings. Recommend a suitable digital communication method and justify your choice, then give one drawback.Show worked answer →
Video conferencing is a suitable method: it allows the team to see and hear each other in real time from different locations, so meetings can be held face to face without anyone travelling, saving time and cost.
It also allows screen sharing and discussion as if in the same room, which suits team meetings better than text.
A drawback is that it depends on a reliable, fast internet connection at every location; a poor connection causes lag or dropped calls, and time-zone differences can make scheduling difficult.
Markers award marks for a suitable method, a justification linked to the scenario (real-time, sees and hears, no travel), and a relevant drawback, up to four marks. The recommendation must fit the need for live group meetings across locations.
WJEC-style2 marksExplain one advantage of using email rather than instant messaging for formal business communication.Show worked answer →
Email is better suited to formal communication because it provides a written record that can be stored, searched and referred to later, and it allows longer, structured messages with attachments.
It is also asynchronous, so the recipient can read and reply when convenient rather than being expected to respond instantly.
Markers give one mark for a valid advantage (written record, attachments, structured/formal, asynchronous) and one mark for explaining why it suits formal business use. A bare "email is more professional" without a reason earns one mark at most.
