What is the predominant wired networking technology that supports data rates up to 100Gbps?

Ethernet.

What are two extensions of Ethernet technology that have enhanced its use in the home?

Powerline carrier (PLC) and Power over Ethernet (PoE).

What significant advantage does Ethernet provide in an enterprise environment?

It allows for scaling the network in terms of distance and data rate using the same protocol.

What technology became the dominant for wireless LANs, originally replacing Ethernet cabling?

Wi-Fi.

What are the essential characteristics of cloud computing defined by the National Institute of Standards and Technology (NIST)?

Broad network access, rapid elasticity, measured service, on-demand self service, resource pooling.

What is the major economic benefit of using Wi-Fi in enterprise networks?

Approximately half of all enterprise network traffic is via Wi-Fi rather than traditional Ethernet.

Which cellular generation was designed to provide higher-quality signals and higher data rates for digital services?

Second Generation (2G).

What does 'network convergence' refer to?

The merger of previously distinct telephony and information technologies and markets.

What technology is essential to implementing the Internet of Things (IoT)?

Wi-Fi.

Name the four generations of deployment the Internet has gone through leading to the Internet of Things (IoT).

First generation, second generation, third generation, and fourth generation.

What key element of unified communications (UC) is built on IP?

The integration of real-time communication services to optimize business processes.

What type of Ethernet supports data rates of 400 Gbps and is being explored by IEEE 802.3?

400 Gbps Ethernet.

What are the two types of Ethernet rates supported by the 25 Gigabit Ethernet Consortium?

Single-lane 25-Gbps Ethernet and dual-lane 50 Gbps Ethernet.

What drives the need for 10-Gbps Ethernet?

Increase in intranet and Internet traffic.

What is cloud networking?

The networks and network management functionality that must be in place to enable cloud computing.

What is a major challenge faced by cloud computing users regarding security?

The customer isn’t always protected and there have been security failures among cloud providers.

What role do sensors and actuators play in the Internet of Things (IoT)?

Sensors observe their environment and report measurements, while actuators operate on their environment.
