Mobile Computing and Iot

Mobile Computing

Mobile Computing allows transmission of data, voice, and video via a computer or any other wireless-enabled device without having to be connected to a physical link.

Features of Mobile Computing

  • It is a portable device that can be used during mobility.
  • Includes mobile communication, mobile hardware, and mobile software.
  • Has the ability to be digitally connected for the purpose of communication.
  • Has the ability to gather and reposnd to real or simulated data unique to a current location, environment, or time.
  • Includes GPS receiver for navigation.

Advantage of Mobile Compuing:

  • It enables users to work from any location at any time.
  • It has made research easier.
  • It supports cloud computing.
  • It saves time for accessing data and information.

Disadvantage of Mobile Computing:

  • It has security concerns.
  • Mobile technology reqyires faster and quality connectivity services.
  • Extensive use of mobile devices results in health problems.

Internet of Things (IoT)

Connection of billions of devices like electronics, sensors, gateways, actuators over a wireless network can be referred to as IoT. Connecting up all different objects and adding sensors to them adds a level of digital intelligence to devices that would be otherwise dumb, enabling them to communicate real-time data without involving a human being.
Driverless trucks, auto-pilot airplanes, a light bulb with a sensor to the smartphones are a few examples of IoT.

Advantages of IoT

  • It automates tasks and helps to improve the quality of a business’s services and reduces the need for human intervention.
  • Helps to operate business operations more efficiently, better understand customers to deliver enhanced customer service.
  • Provides improved communication between connected electronic devices.
  • Transferring data packets over a connected network saves time, effort, and money.
  • It has the ability to access information from anywhere at any time on any device.

Disadvantages of IoT

  • As the number of connected devices increases and more information is shared between devices, the chances of the system being attacked also increases.
  • Organizations may eventually have to deal with massive number of IoT devices, and collecting and managing the data from all those devices will be challenging.
  • If there’s a bug in the system, every connected device will likely become corrupted.
  • Since there’s no international standard of compatibility for IoT, it’s difficult for devices from different manufactures to communicate with each other.
