Is the official RBSE Secondary (Class 10) Telecom exam multiple-choice only?

No. Official RBSE papers mix objective and constructed-response tasks and vocational subjects also require practical/skill evidence. The 100 questions here are an English-language MCQ study adaptation for concept practice only.

What are full marks and duration for RBSE Telecom?

RBSE Class 10 / Praveshika subject schemes in the official syllabus commonly use Theory 80 + Sessional 20 = 100 marks with a 3 hour 15 minute theory paper. Confirm the exact scheme for code 112 in the current RBSE syllabus PDF on rajeduboard.rajasthan.gov.in.

What is the passing score?

Minimum 33% marks in the subject as per RBSE Secondary/Praveshika examination regulations (confirm current session circulars).

How much does the exam cost?

As per RBSE annual examination fee notification for school/private candidates (commonly published figures for the 2026 Secondary/Praveshika cycle have been about INR 600 regular / INR 650 private for the full board form — confirm the current circular on rajeduboard.rajasthan.gov.in; subject papers are not separately priced on this page).

Where are official statistics and syllabus?

Subject-wise 2026 result statistics and board materials are published by RBSE at https://rajeduboard.rajasthan.gov.in/statistics2026.htm and syllabus PDFs under anudeshika / books sections of https://rajeduboard.rajasthan.gov.in. Prefer primary board PDFs over third-party summaries.

Is this bank an official RBSE translation?

No. OpenExamPrep publishes one English-language practice bank per exam ID. Target-language terms and texts may appear when they are integral to the skill, but stems, explanations, and SEO copy are English study adaptations — not official translations or language-environment simulations.

How should I use MCQs for a mixed written/practical paper?

Use MCQs for daily concept drills and self-check. Also practise full written answers from RBSE model papers and complete school practical/skill assessments under timed conditions.

1What does telecommunication primarily mean?

A.Communication of information over a distance using electrical, optical, or radio signals

B.Only face-to-face conversation in the same room

C.Printing books and newspapers only

D.Storing data on paper files without transmission

Explanation: Telecommunication is the exchange of information (voice, data, video) over distance using electrical, optical, or electromagnetic media.

2Which statement correctly describes a digital signal used in modern telecom?

A.It varies continuously without discrete steps

B.It represents information as discrete levels such as 0 and 1

C.It can only travel through air, never through cable

D.It never needs a clock or timing reference in networks

Explanation: Digital signals use discrete states (typically binary 0/1) to represent information, which supports error control and efficient processing.

3The SI unit of signal frequency in telecommunications is the:

A.Ohm (Ω)

B.Decibel (dB)

C.Hertz (Hz)

D.Farad (F)

Explanation: Frequency is cycles per second, measured in Hertz (Hz) and multiples such as kHz, MHz, and GHz.

4A telephone conversation where both people can speak and listen at the same time is an example of:

A.Simplex communication

B.Broadcast-only communication

C.Store-and-forward only

D.Full-duplex communication

Explanation: Full-duplex allows simultaneous two-way transmission, as in a normal phone call.

5A computer network confined to a single home, school lab, or small office building is typically a:

A.LAN (Local Area Network)

B.WAN (Wide Area Network)

C.Satellite backbone only

D.International undersea cable only

Explanation: A LAN covers a limited geographic area such as a building or campus.

6Why is modulation used in many radio and telecom systems?

A.To permanently delete noise from the universe

B.To impress information onto a carrier wave suitable for transmission

C.To replace batteries inside every handset automatically

D.To convert copper into optical fiber

Explanation: Modulation places baseband information onto a higher-frequency carrier so it can be transmitted efficiently over radio or other channels.

7In traditional telephony, PSTN stands for:

A.Private Secure Tunnel Node

B.Packet Stream Transfer Number

C.Public Switched Telephone Network

D.Power Supply Terminal Network

Explanation: PSTN is the Public Switched Telephone Network—the classic circuit-switched phone system.

8In telecom, bandwidth of a channel most commonly refers to:

A.The physical thickness of the outer cable jacket only

B.The colour of the connector plastic

C.The number of employees at a call centre

D.The range of frequencies the channel can pass effectively

Explanation: Bandwidth is the usable frequency range (or related capacity) of a transmission channel.

9As a signal travels a long distance through a cable without amplification or regeneration, what typically happens?

A.Signal strength decreases due to attenuation

B.Signal frequency automatically doubles every kilometre

C.Noise completely disappears

D.The cable becomes superconducting at room temperature

Explanation: Attenuation is progressive loss of signal power with distance in the medium; boosters/amplifiers/regenerators counteract it.

10Signal-to-noise ratio (SNR) is important because:

A.SNR measures only the colour of LED indicators

B.A higher SNR generally means a clearer recoverable signal relative to noise

C.SNR is the same as cable bend radius

D.SNR only applies to paper forms, not networks

Explanation: SNR compares desired signal power to noise power; higher SNR supports better reception and fewer errors.
