(23)List down benefits and limitations of mobile computing.
Answer:
Advantages of Mobile Computing: Mobile computing has changed the complete landscape of our day-to-day life. Following are the major advantages of Mobile Computing.
(1)Flexibility: A user can work without being in a fixed position. This has enabled users to work from anywhere as long as there is a connection established.
(2)Time: The time consumed or wasted while travelling from different locations or to the office and back, has been slashed by using mobile computing technologies.
(3)Streamlining Business:
(4)Ease of Research: Research has been made easier, since users earlier were required to go to the field and search for facts and feed them back into the system.
(5)Enhanced Productivity: Users can work efficiently and effectively from whichever location they find comfortable. This in turn enhances their productivity level.
Drawbacks of Mobile Computing:
(1)Quality of connectivity:
(3)Power Consumption: Due to the use of batteries in the mobile devices, devices do not tend to last long. If there is no regular power recharges are not made, then mobile devices will certainly be shut down.
(4)Transmission interferences: Weather, terrain, and the range from the nearest signal point can all interfere with signal reception. Reception in tunnels, some buildings, and rural areas is often poor.
(5)Potential health hazards:

(2)Time: The time consumed or wasted while travelling from different locations or to the office and back, has been slashed by using mobile computing technologies.
(3)Streamlining Business:
- It enables to improve management effectiveness by enhancing accurate flow of information in faster manner.
- For example sales personnel can update work order in real time basis, facilitating excellent communication
(4)Ease of Research: Research has been made easier, since users earlier were required to go to the field and search for facts and feed them back into the system.
(5)Enhanced Productivity: Users can work efficiently and effectively from whichever location they find comfortable. This in turn enhances their productivity level.
Drawbacks of Mobile Computing:
(1)Quality of connectivity:
- Mobile device needs either WiFi connectivity or mobile network connectivity such as GPRS, 3G or 4G network.
- If device is not near (or not in range) any of these connections, the access to the internet is very limited.
- Accessing a WiFi network from mobile device is risky, because Wired Equivalent Privacy (WEP) and Wireless Protected Access (WPA) security can be bypassed easily.
- Mobile devices are unsafe to connect to Virtual Private Networks (VPNs), as these are vulnerable to attack, and also syncing devices might lead to serious security concerns.
(3)Power Consumption: Due to the use of batteries in the mobile devices, devices do not tend to last long. If there is no regular power recharges are not made, then mobile devices will certainly be shut down.
(4)Transmission interferences: Weather, terrain, and the range from the nearest signal point can all interfere with signal reception. Reception in tunnels, some buildings, and rural areas is often poor.
(5)Potential health hazards:
- Questions concerning mobile phone radiation and health have been raised by various research studies.
- People who use mobile devices while driving are often distracted from driving and are thus assumed more likely to be involved in traffic accidents.
