Weekly Questions Week 8

Weekly Questions (Week 8)
Chapter Seven: Networks, Telecommunications and Mobile Technology

Wireless Technologies(Image 1)
1.Explain the business benefits of using wireless technology.
Wireless technology has provided businesses with many benefits. Wireless technology allows the user to access the internet through satellites, allowing personnel access to information such as reports, and files whenever they are needed. This has also enabled employees to work in any location, not just in the office. As such, this allows employees and owners to balance work and private life. Another benefit of wireless technology is the ability to manage and ‘keep track’ of inventory. Through the use of RFID technology, businesses are able to maintain ‘up-to-date’ information.


2. Describe the business benefits associated with VoIP

Benefits associated with Voice over IP include: 
  •  Cost saving – transmits national and international calls over internet and existing network, with little or no call charges
  • Productivity gains – conference and video calling allows for easy communication between business personnel. 
  • Able to transfer reports, pictures and other documents to personnel instantly whenever they are needed
3. Compare LANs and WANs
Example of LAN (Image 3)
Local area networks (LANs) are a connection of a group of computers or devices in a small proximity/limited geographical area. However, Wide area networks (WANs) are a connection of LANs, computers and other devices in a wider geographical area, whereby users are able to use computers in one location to communicate with other computers in another location.

4. Describe RFID and how it can be used to help make a supply chain more effective.
 Radio frequency identification (RFID) technologies use tags which transmits data/information to an electronic reader in the form of radio waves. There are 2 forms of RFID, passive and active. Passive RFID have no internal power source and can ‘power up’ to send data with a faint signal from the RFID reader, however active RFID have internal power and are able to send stronger signals and more accurate data.

Radio frequency identification technologies can make a supply chain more effective because it allows the business to reduce the time and costs associated with tracking assets such as inventory. Items equipped with these tags only need to be in the range of a RFID reader to receive and send data to the server. This reduces the time and costs of workers needing to physically scan barcodes.

5. Identify the advantages and disadvantage of deploying mobile technology
Advantages:
  • The ease of sharing information
  • Provides flexibility, user convenience
  • Ease of implementation 
  • Able to manage inventory, data is continuously up-to-date
  • Allow employees to communicate more efficiently

Disadvantages:
  • Radio wave interference may occur if there are multiple antennas. This may disrupt signals and cause the loss of data
  • Sending and receiving data is slower compared to fiber optics
