Mobile Computing MCQs: Solved Questions on Concepts, Features and Applications

Mobile-computing questions often begin with a simple definition, then mix in easy-to-confuse standards such as AMPS, IS-95, GPRS, GSM, UMTS, EDGE, Bluetooth, and CDMA. Attempt each question before reading its answer and explanation. Use the Computer Networks MCQs collection for a broader protocol set. Individual solved-page links are unavailable for these ten items, so the Computer Networks lessons and PYQs hub is the stable route to related practice.

Mobile computing concept and portability MCQs

Question 1

UP Police 2016

Which of the following statement is wrong related with mobile computing?

1. It does not include all aspects of wireless communication.

2. It allows to calculate from any location.

3. Mobile software is related to the user's characteristics and need.

4. Mobile Hardware, Mobile equipment or equipment has an affinity, which gives or uses the mobile service.

Answer: Option 4.

Mobile computing combines portable hardware, mobile software, and wireless communication. Portability, location-independent computation, and software adapted to user or device needs are recognisable characteristics. Option 4 does not give a coherent standard definition of mobile hardware, so it is the wrong statement.

Question 2

UP Police 2016

Which of the following is an advantage of mobile computing?

1. Quality of Connectivity

2. Easily transferable from one place to another place

3. Use of Electricity

4. Security

Answer: Option 2.

Portability is the advantage. A mobile device can be carried between places while the user continues computing. Connectivity quality and security can become constraints, while electricity is a requirement rather than a benefit.

Cellular generations and mobile standards MCQs

Question 3

UGC NET 2018

Which of the following statements are true ?

(a) Advanced Mobile Phone System (AMPS) is a second generation cellular phone system.

(b) IS - 95 is a second generation cellular phone system based on CDMA and DSSS.

(c) The Third generation cellular phone system will provide universal personnel communication.

Code :

1. (a) and (b) only

2. (b) and (c) only

3. (a), (b) and (c)

4. (a) and (c) only

Answer: Option 2.

Check each statement before reading the code. AMPS is a first-generation analogue system, so (a) is false. IS-95 is a 2G CDMA system that uses direct-sequence spread spectrum, and the stated 3G aim is universal personal communication, so (b) and (c) are true.

Question 4

UGC NET 2014

Match the following with respect to the mobile computing technologies :

Codes :

1. a-iii; b-iv; c-ii; d-i

2. a-iv; b-i; c-ii; d-iii

3. a-ii; b-iii; c-iv; d-i

4. a-ii; b-i; c-iv; d-iii

Answer: Option 2.

Complete all four pairs: GPRS -> iv, GSM -> i, UMTS -> ii, and EDGE -> iii. In the order a, b, c, d, this gives a-iv; b-i; c-ii; d-iii. That ordered code is Option 2.

Bluetooth and multiple-access MCQs

Question 5

UGC NET 2019

Piconet is a basic unit of a bluetooth system consisting of __________ master node and up to  _________ active slave nodes.

1. one, five

2. one, seven

3. two, eight

4. one, eight

Answer: Option 2.

A piconet has one master and up to seven active slaves. A 3-bit active-member address provides 2^3 = 8 codes, but 000 is reserved, so 001 through 111 identify seven active slaves. The exam trap is to read eight address codes as eight slaves.

Question 6

In Mobile Computing, Which of the following data transfer techniques allow the use of entire bandwidth simultaneously?

1. TDMA

2. FDMA

3. CDMA

4. None of the above

Answer: Option 3.

FDMA gives users different frequency bands, TDMA gives them different time slots, and CDMA lets them use the same broad band at the same time while codes separate them. Let user A have code (+1, +1) and data bit +1, giving chip vector (+1, +1), while user B has code (+1, -1) and data bit -1, giving (-1, +1). Their shared signal is (0, +2); correlation gives 0(1) + 2(1) = +2 for A and 0(1) + 2(-1) = -2 for B, which recover +1 and -1 after division by the two-chip code length. CDMA is therefore the technique that uses the entire bandwidth simultaneously.

Mobile computing applications and Android MCQs

Question 7

UGC NET 2017

Which of the following is/are true w.r.t. applications of mobile computing ?

(A) Travelling of salesman

(B) Location awareness services

1. (A) true; (B) false.

2. Both (A) and (B) are true.

3. Both (A) and (B) are false.

4. (A) false; (B) true.

Answer: Option 2.

Travelling-salesman applications support route optimisation in mobile logistics, while location-aware services include maps and navigation. A phone-based planner can compare Depot -> A -> B -> C -> Depot = 4 + 3 + 5 + 6 = 18 km with Depot -> B -> A -> C -> Depot = 7 + 3 + 8 + 6 = 24 km, then choose the 18 km route while using live location. Both statements describe applications that combine computation with mobility and location, so both are true.

Question 8

UGC NET 2024

Android is a mobile operating system developed by ________________.

1. IBM

2. Apple

3. Microsoft

4. Google

Answer: Option 4.

Google is the expected exam answer. Android Inc. created the original platform; Google acquired the company in 2005 and has led Android development since. Apple develops iOS, while Microsoft and IBM are not the developer named by the question.

Mobile cloud and device-limitation MCQs

Question 9

Challenges in Mobile Cloud Computing are

(i) High Bandwidth

(ii) Service availability

(iii) Low bandwidth

1. Only i and ii

2. Only ii and iii

3. Only i and iii

4. All of the above

Answer: Option 2.

Service availability and low bandwidth are challenges because a cloud-backed mobile application needs both a usable network path and a reachable service. For an idealised transfer, 200 MB = 1,600 Mb; at 5 Mbps, the minimum time is 1,600 / 5 = 320 seconds, or 5 minutes 20 seconds. At 50 Mbps, it is 1,600 / 50 = 32 seconds, before protocol overhead. High bandwidth is desirable capacity rather than a challenge, so the exact selected pair is (ii) and (iii).

Question 10

DSSSB 2023

Which of the following are limitations of mobile computing?

Limitations:

i) Device mobility

ii) Power consumption

iii) Human interface with device

iv) Range and Bandwidth

v) Transmission interferences

vi) Wireless connectivity

1. ii, iii, iv and v only

2. i, ii and v only

3. i, ii and iv only

4. i, iii and vi only

Answer: Option 1.

The intended limitations are power consumption, a constrained human-device interface, limited range or bandwidth, and transmission interference. These correspond to ii, iii, iv and v. Device mobility and wireless connectivity are treated here as defining capabilities, not as members of the limitation set.

What these mobile computing MCQs actually test

The standards become easier to revise when each exam cue is tied to one value and one likely confusion.

Three operations resolve most questions in this set. First, reject a false statement before looking at the answer codes, as in the AMPS question. Second, complete every pair in a matching question and only then choose the ordered code. Third, separate a defining feature such as mobility from a resource constraint such as power, interface size, range, bandwidth, or interference.

If you want another protocol-oriented solved set, continue with Application Layer MCQs. The GATE CS Exam Preparation Courses and Test Series page is the wider option if you are preparing the full syllabus, not just this topic.

The short version and the next practice step

Keep four anchors ready: mobile computing combines portable hardware, software, and wireless communication; a piconet is 1 + up to 7; CDMA shares the band through codes; and mobile systems trade portability for constraints involving power, interface, range, bandwidth, and interference.

For topic practice, use the Computer Networks lessons and PYQs.

Readers preparing the complete CS syllabus can use GATE Guidance by Sanchit Sir. If you only need mobile-computing revision, first redo this set without looking at the answers.
