On the internet, which of the following is not considered a common means of personal communication between individual users?

Introduction / Context:
This question tests your understanding of common internet based communication services. Personal communication on the internet includes various tools that allow individuals to exchange messages in real time or with some delay. Examples include instant messaging, chat services, email and video calls. Exam setters sometimes mix genuine terms with invented names to check whether you can distinguish real communication methods from distractors. Recognising which term does not belong in the list is key to answering correctly.

Given Data / Assumptions:

• The question asks which option is not a means of personal communication on the internet.
• Options mention instant messaging, chat, electronic mail, Instanotes and video calling.
• We consider widely used technologies and services that allow person to person communication online.
• Instanotes appears as an unfamiliar or invented term.

Concept / Approach:
Instant messaging, online chat, email and video calling are all established forms of personal communication on the internet. Instant messaging services and chat rooms allow real time text conversations. Electronic mail, or email, supports asynchronous message exchange. Video calling lets people talk face to face using cameras and microphones. Instanotes, however, is not recognised as a standard or popular internet communication term in textbooks or everyday usage. It may sound similar to instant messaging or notes applications, but it is not specifically known as a common communication method. Therefore, Instanotes is the correct answer because it stands out as the option that is not widely used or defined as a mainstream internet communication channel.

Step-by-Step Solution:

Verification / Alternative check:
Lists of internet communication tools in computer awareness books usually include email, chat, instant messaging, social networking and voice or video calls. They do not list Instanotes as a category. Searching major communication platforms also reveals no standard protocol or major application category with this name. In contrast, the other options match widely used technologies such as instant messaging applications, chat platforms and video conferencing tools. This absence from recognised lists supports the conclusion that Instanotes is not considered a common means of personal communication on the internet in exam style terminology.

Why Other Options Are Wrong:

• Instant messaging: A real time text communication method, definitely a common personal communication tool.
• Online chat: Chat rooms and chat windows are classic forms of internet conversation.
• Electronic mail (email): One of the oldest and most common means of exchanging messages over the internet.
• Video calling: Widely used through video conferencing apps and social media platforms for personal conversations.

Common Pitfalls:
Some learners may not recognise Instanotes and feel tempted to choose None of these if such an option is available in similar questions. Another pitfall is to assume video calling is only for business meetings and not personal communication, even though people frequently use it for family and friends. The key is to focus on whether the method enables person to person exchange of information over the internet. Instant messaging, chat, email and video calls all clearly do, while Instanotes does not correspond to any standard form, making it the correct outlier.

Final Answer:
The option that is not a recognised common means of personal communication on the internet is Instanotes.
