Week Eight - Networks & Wireless
1. Explain the business benefits of using wireless technology.
Benefits include:
- Business 24/7 - 365 days a year
- Increased productivity
- Access to information anywhere and anytime
- Increased speed- added convenience
2. Describe the business benefits associated with VoIP
The biggest benefit VoIP provides to business is that VoIP calls over a company’s intranet do not receive charges from a telecommunication company as they run on a private network. Costs are also reduced when calls are made over the internet, especially international calls which cover large distances. Skype is an example VoIP. It enables telephone and video calls over the internet.
3. Compare LANs and WANs
A local area network (LAN) connects computers within a small geographical region such as a business’ premises. LANs connect via Ethernet connections, routers and the internet to share data and internet connections. Firewalls are used to prevent unauthorised access.
A wide area network (WAN) varies from a LAN as it connects computers over a wide geographical region. LANs rely upon cabled connection whilst WAN’s rely upon the internet and wireless forms of communication such as satellites to connect computers together. WANs may be implemented across multinational corporations to enable them to share information across offices.
4. Describe RFID and how it can be used to help make a supply chain more effective.
Radio Frequency Identification is a method of tracking inventory. Small tags are used which receive and transmit radio signals to identify what the inventory is and where it is. Passive RFID tags have no internal power flow. Active RFID tags operate upon the same basis but have an active power flow.RFID is a low cost method of increasing the efficiency of the supply chain as cargo can easily be identified and located. This technology also enables downstream users, such as customers, to track where a product is located.
5. Identify the advantages and disadvantage of deploying mobile technology
Mobile technology is any form of technology that can travel with its user. When connected to the internet mobile technology can provide real time information. For example, the iPhone.
Advantages:The mobility of the technology means that it is convenient. An employee can access important information in real time at any location.Mobile technology is relatively cheap.The processors of mobile technology are powerful enough to provide real time information.The portability of mobile devices enables a broad reach as users can be reached instantly.
Disadvantages:Mobile technology is convenient its processing power is limited and a pc may be needed to run complex programs.Mobile devices are insecure. There is a threat of Bluetooth hacking which could cause significant business and personal information to be lost.
