Wireless Fidelity (wi-fi) is a means of linking computers using infrared or radio signals. Wi-fi has many technological advantages for people on the move who would like access to the Internet in airports, restaurants and hotels. Wi-fi is also gaining acceptance as a home or neighbourhood network, oermitting an assortment of laptop and desktop computers to share a single broadband access point to the Internet. Employees are able to easily move their laptops from office to office and can connect to the network in places such as lunchrooms and patios.
2. Describe the business benefits associated with VoIp.
Voice over IP (VoIP) uses TCP/IP technology to transmit voice calls over Internet technology. VoIP uses existing network and Internet infrastructure to route telephone calls more efficiently and inexpensively than traditional telephone services.
Features available when using VoIP include:
- call waiting
- caller ID
- three way calling
- easy navigation
- calender integration
3. Compare LANS and WANS
A local area network (LAN) is designed to conect a group of computers in close proximity to each other such as in an office building, a school or a home. A LAN is useful for sharing resources like files, printers, games, or other applications.
A wide area network (WAN) spans a large geographic area, such as a state, province or country. WANS often connect multiple smaller networks, such as local area networks.
4. Describe RFID and how it can be used to help make a supply chain more effective
Radio frequency identifications (RFID) technologies use active or passive tags in the form of chips or smart labels that can store unique identifiers and relay this information to electronicn readers.
RFID can help make a supply chain more effective as when a tag is placed on an item, it automatically radios its location to RFID readers on shop shelves, checkout counters, loading-bay doors and shopping carts. With RFID tags, inventory is taken automatically and continuously. RFID can cut costs by requiring few workers for scanning items; they also can provide more current and more accurate information to the entire supply chain.
5. What is some new emerging technologies that could change a specific industry?
Satellite technologies: A communications satellite is a big microwave repeater in the sky; it contains one or more transponders that listen to a particular portion of electromagnetic spectrum, amplifying incoming signals and re-transmitting them back to Earth. A microwave transmitteruses the atmosphere (or outer space) as the transmission medium to send the signal to the microwave receiver.
