Q

What is packet switching?

A
  • Allows millions of users to send chunks of data across the Internet concurrently
  • Messages are broken down into small fixed bundles of data called packets
  • Based on the concept of turn taking, packets from each user are alternated in the shared network
  • Does not require a dedicated circuit

Q

What is a ring network?

A

is configured in the shape of a circle with each node connecting to the next node. Messages travel around the circle in one direction.

17
Q

What is a wide-area network (WAN)?

A
  • Span large geographical distances
  • Typically used to connect two or more LANs
  • Most universal and powerful WAN is the Internet
18
Q

What is a metropolitan-area network (MAN)?

A
  • A network that spans a metropolitan area, usually a city and its major suburbs
  • Typically use a wireless infrastructure as well as high-speed connections using fiber-optic technologies.
19
Q

What are the benefits and drawbacks of a twisted pair?

A
  • inexpensive; easy to install and reconfigure

- Highly susceptible to EML, eavesdropping, and attenuation; unsuitable for high speeds

20
Q

What are the benefits and drawbacks of a coaxial?

A
  • higher bandwidth than twisted pair; lower susceptibility to EML, eavesdropping, and attenuation than twisted pair
  • more expensive than twisted pair; more difficult to install, reconfigure, and manage attenuation than twisted pair; bulky
21
Q

What are the benefits and drawbacks of a fiber-optic?

A
  • very high bandwidth; low attenuation and immune to EMI and eavesdropping
  • expensive cable and hardware; complex installation and maintenance
22
Q

What are the advantages and disadvantages of wireless transmission media?

A
  • Most wireless media is susceptible to EMI and eavesdropping
  • Costs start out moderate with high frequency radio and terrestrial microwave, and rise sharply with satellite microwave
23
Q

What is the internet?

A
  • A large worldwide collection of networks that use a common protocol (TCP/IP) to communicate with each other.
  • Created in the early 1970s by DARPA (Defense Advanced Research Projects Agency) to link scientists and university
24
Q

What is an IP address?

A
  • Each domain (rowan.edu) is associated with one or more IP addresses, which serves as a destination address
  • Any device on a network must have its own unique address
  • Format: written as 4 numbers (from 0-255) separated by periods.
  • ——-Example: 134.121.0.99
25
Q

What is a domain system name?

A
  • Provides a service analogous to an address book lookup
  • Special DNS servers on the internet are dedicated to performing the translation from a domain name to an IP address and vice versa.
26
Q

What is IPv6?

A
  • The world will run out of IP addresses using the existing addressing convention by 2012 or 2013
  • IPv6 is a new version of the IP addressing schema which uses 128-bit addresses, or more than a quadrillion unique addresses
27
Q

What is internet2?

A
  • Internet that focuses on:

—-more effective routing practices

—-different levels of service depending on the type and importance of data

—-advanced applications

28
Q

What is voice over IP (VoIP)?

A

Uses the Internet Protocol (IP) to deliver voice information in digital form using packet switching

29
Q

What is a virtual private network (VPN)?

A

A secure connection between two points across the Internet to transmit corporate data. Provides a low-cost alternative to a private network.

30
Q

What is the world wide web?

A
  • The most popular Internet service
  • A system with universally accepted standards for storing, retrieving, formatting, and displaying information in a networked environment.
31
Q

What is hypertext markup language (HTML)?

A

lets you specify the structure of a document, format text, add graphics, sound, and video, and save it all in a text file that any computer can read.

32
Q

What is hypertext transfer protocol (HTTP)?

A

the set of standards used by web servers to process user requests for web pages.

33
Q

What is a web server?

A

software for locating and managing stored Web pages.

34
Q

What are wireless sensor networks (WSNs)?

A
  • Networks of interconnected wireless devices that are embedded into the physical environment to provide measurements of many points over large spaces
  • Devices contain built-in processing, storage and radio frequency sensors and antennas
  • May be used to monitor traffic or building security, or to detect hazardous substances in the air
35
Q

What is radio frequency identification (RFID)?

A
  • Provide powerful technology for tracking the movement of goods throughout the supply chain
  • Uses tiny tags with embedded microchips to transmit data about an item to a RFID reader that passes data on to network
  • RFID tags do not require line of sight
