WGU Introduction-to-IT Dumps Questions Answers

Wireless headphones typically connect to a smartphone using Bluetooth, which is an example of a personal area network. In Information Technology, a personal area network is a short-range network centered around an individual’s devices, usually within a few meters. PAN technology is designed for low power usage and convenient device pairing, making it ideal for accessories such as headphones, smartwatches, fitness trackers, and wireless keyboards. A local area network covers a larger area such as a home, office, or campus and commonly uses Ethernet or Wi-Fi to connect computers and network devices. A wide area network spans large geographic distances and connects networks across cities, countries, or continents, often using leased lines or internet infrastructure. Extended area network is not a standard category used in most networking fundamentals curricula compared with PAN, LAN, MAN, and WAN. Since the connection between headphones and a phone is short-range and personal, it is best classified as a personal area network. Therefore, the correct answer is PAN.

A network architect is a professional responsible for designing and implementing computer networks that meet the needs of an organization. Here are the key aspects of their role:

1.Designing Networks: Network architects create network infrastructures that support an organization’s goals. They work with both hardware and software components to plan and design data communication networks. These networks can range from smaller local area networks (LANs) to larger wide area networks (WANs) and intranets.

2.Installation and Implementation: Once the network design is complete, network architects oversee the installation and implementation process. They ensure that routers, modems, cables, and other necessary hardware and software are properly set up. They also determine the layout of network components within buildings or across cities and countries.

3.Security Management: Network architects play a crucial role in managing information and network security. They implement security measures to protect the network from unauthorized access, data breaches, and other threats.

4.Upgrades and Maintenance: These professionals continuously monitor the network’s performance and assess future needs. They perform upgrades to hardware and software as required. Regular maintenance and minor repairs are essential to keep the network operating smoothly and avoid downtime.

5.Documentation: Network architects maintain thorough documentation of networks, including drawings, descriptions, and configurations. This documentation helps ensure efficient management and troubleshooting.

6.Communication and Collaboration: Network architects often work alongside IT specialists and communicate with management staff. They use their understanding of the organization’s business goals to develop network systems that align with those objectives.
