UGC NET Questions (Paper – 1)

Voice over IP refers to methods and technologies for delivering voice communications over IP networks. It converts voice signals into digital packets, transmits them over the network and reconverts them at the destination. Services like internet calling and conferencing rely on VoIP. Therefore, Voice over IP is the correct term.

Option A:
Option A is correct because Voice over IP is the standard expansion of VoIP used in networking and communication literature.

Option B:
Option B, Video on Internet, would refer to video streaming rather than voice calling and is not the established acronym.

Option C:
Option C, Voice only Protocol, is not a recognised term and does not reflect the network oriented nature of VoIP.

Option D:
Option D, Virtual office Internet, describes a vague concept and not the specific technology for voice transmission.

Statements A, B and D correctly describe how video conferencing works, while statement C is false. Video conferencing connects participants who may be in different locations, using audio, video and network connectivity. Modern platforms support features such as screen sharing and document collaboration to enhance interaction. It is therefore incorrect to state that video conferencing demands physical co-presence, so A, B and D only form the correct set of statements.

Option A:
Option A is incorrect because it lists only A and B as correct, leaving out D. While A and B are true, statement D is also correct in highlighting collaboration features that are widely available in contemporary video conferencing tools. Omitting D makes this option incomplete.

Option B:
Option B is incorrect because it includes statement C along with A and B. Statement C contradicts the essential purpose of video conferencing, which is to allow interaction at a distance. Including this false statement invalidates the combination.

Option C:
Option C is incorrect because it groups B, C and D as correct. Although B and D are true, C is false and claims the opposite of what video conferencing is designed to achieve. A correct answer cannot contain that statement.

Option D:
Option D is correct because it brings together A, B and D while excluding C. It accurately captures the technical requirements, real-time nature and collaborative features of video conferencing, without assuming physical co-location.

For group members who are geographically separated, instant messaging services allow them to exchange text messages in real time. Features like group chats, emojis and file sharing make coordination easier and more dynamic than using static media. Such tools support collaborative learning, brainstorming and quick doubt clearance. Therefore, they are ideal for synchronous text-based discussions.

Option A:
This option correctly highlights the synchronous nature of chat platforms, where participants can respond immediately to each other. Many educational projects now integrate such tools within LMS or use dedicated apps to enhance group communication.

Option B:
An offline word processor is meant for individual document creation and editing. Without network connectivity, it cannot support real-time interaction among multiple learners in different locations. Any sharing would require manual transfer of files.

Option C:
A calculator is specialised for numeric operations and does not provide communication capabilities. It cannot host group conversations or store discussion threads.

Option D:
A notice board is useful for one-way announcements but not for interactive back-and-forth dialogue. Messages must be physically posted and read, which is slow and not real time.

Video conferencing systems transmit both audio and video signals to enable interactive meetings among people in different locations. They are widely used for virtual classes, webinars and administrative meetings. ICT infrastructure such as cameras, microphones and bandwidth are essential. Hence, the meetings described are called video conferencing.

Option A:
Option A is correct because video conferencing explicitly denotes real time audio visual communication over networks.

Option B:
Option B, e mailing, involves asynchronous text based messages and does not provide live two way interaction.

Option C:
Option C, text chatting, offers real time communication but usually without integrated audio visual components.

Option D:
Option D, data warehousing, concerns storing large volumes of structured data for analysis and has nothing to do with meetings.
