UGCNET Questions

The CC field allows senders to copy additional people for information, and their addresses appear in the message header visible to all. BCC is useful when the sender wants to protect the privacy of some recipients, such as in mass emails. Understanding this distinction helps maintain confidentiality and professionalism in ICT-mediated communication.

Option A:
This option correctly states the visibility difference between the two fields without exaggerating their functions. It reflects common email client behaviour and is essential for responsible use in institutional settings.

Option B:
Saying that both fields hide all addresses from everyone would make email headers useless and contradict actual implementations. Normal recipients do see at least some addresses.

Option C:
Claiming that CC recipients never receive messages or that BCC recipients always receive messages twice is baseless. Both sets receive one copy unless technical errors occur.

Option D:
Attachment handling is independent of CC and BCC usage. Any recipient field can receive messages with or without attachments.

Digital communication represents information in discrete binary form, which allows receivers and repeaters to distinguish valid bits even when some noise is present. Regenerators can restore digital signals to near-original shape at intermediate points. This leads to lower error rates and better quality over long distances, so Option A correctly states a major advantage.

Option A:
This option is incorrect because digital communication is actually the one closely associated with computers and ICT systems. Digital networks form the backbone of computer communication, so saying they can never be connected contradicts reality.

Option B:
Option C is wrong because digital signals are precisely what most modern electronic devices store and process. Memory chips, disks and processors all handle digital data.

Option C:
Option D about handwriting misunderstands the nature of digital communication, which uses electronic signals, not pen and paper.

Option D:

ICT fundamentally involves the convergence of computers, communication networks and digital media. This integration allows users to handle text, audio, video and data in seamless ways. In education, this enables activities like online teaching, digital libraries and administrative automation. Therefore, the feature that highlights integration of computing and communication for digital information is the most accurate description.

Option A:
This option wrongly narrows ICT to textbook printing, which is a traditional activity that may not involve digital technologies at all. It ignores communication networks and interactive media, so it fails to reflect the core nature of ICT.

Option B:
This option captures that ICT links computers with communication systems to manage information throughout its life cycle. It emphasises digital processing and transmission, which underpin tools such as email, LMS and MOOCs. This makes it a good representation of ICT characteristics.

Option C:
Option C focuses only on loudspeakers, which are simple audio devices and do not represent the full breadth of ICT. Without computing and networking, this example is too limited to define ICT.

Option D:
Option D confuses ICT with physical infrastructure development. Buildings may host ICT, but construction activities are not themselves part of ICT characteristics.
