Across
- 3. Provides the physical connection to the network at the PC or other host device
- 6. Digital Subscriber Lines provide a high bandwidth, always on, connection to the Internet. DSL runs over a telephone line. In general, small office and home office users connect using Asymmetrical DSL (ADSL), which means that the download speed is faster than the upload speed.
- 7. Interactive websites where people create and share user-generated content with friends and family
- 9. refers to the technologies that support the infrastructure and the programmed services and rules, or protocols, that move data across the network.
- 11. Examples include copper, fiber and wireless
- 13. capable of delivering data, voice, and video between many different types of devices over the same network infrastructure
- 15. The availability of satellite Internet access is a real benefit in those areas that would otherwise have no Internet connectivity at all. Satellite dishes require a clear line of sight to the satellite.
- 16. limits the impact of a failure, so that the fewest number of devices are affected.
- 17. Web pages that groups of people can edit and view together
- 21. Hosts that request information
- 22. identify the physical location of intermediary devices and cable installation.
- 24. reserved circuits within the service provider's network that connect geographically separated offices for private voice and/or data networking. The circuits are typically rented at a monthly or yearly rate. They can be expensive.
- 26. Hosts that provide information
- 29. Describes the state of a network when the demand on the network resources exceeds the available capacity
- 30. Typically offered by cable television service providers, the Internet data signal is carried on the same cable that delivers cable television. It provides a high bandwidth, always on, connection to the Internet.
- 31. An inexpensive option that uses any phone line and a modem. The low bandwidth provided by a dial-up modem connection is usually not sufficient for large data transfer, although it is useful for mobile access while traveling.
- 32. Type of websites that gives anyone a means to communicate their personal thoughts to a global audience without technical knowledge of web design
- 34. Identify devices, ports, and addressing scheme.
- 37. Applications can be accessed over the Internet through a subscription.
Down
- 1. Real-time communication between two or more people
- 2. Specialized ports on a networking device that connect to individual networks. Because routers are used to interconnect networks, the ports on a router are referred to as network interfaces.
- 4. Something that helps people work together on a particular file or piece of software
- 5. Used by companies to provide suppliers, vendors, and customers limited access to corporate data to check order status, inventory, and parts lists
- 8. Examples include routers, switches and wireless access points
- 10. Similar to a LAN but wirelessly interconnects users and end points in a small geographical area.
- 12. Private networks in use by just one company
- 14. available in various formats. A popular choice is Symmetric Digital Subscriber Lines (SDSL) which is similar to the consumer version of DSL, but provides uploads and downloads at the same speeds.
- 18. Having multiple paths to a destination
- 19. Type of network provides access to users over a large geographical area
- 20. splits traffic into packets that are routed over a shared network. Helps create redundancy
- 23. Type of network infrastructure is designed to support file servers and provide data storage, retrieval, and replication using high-end servers, multiple disk arrays and Fiber Channel interconnection technology
- 25. Type of network provides access to users over a small geographical area
- 27. A connector or outlet on a networking device where the media is connected to an end device or another networking device.
- 28. Audio-based medium that allows people to deliver their recordings to a wide audience
- 30. uses a cell phone network to connect. Wherever you can get a cellular signal, you can get cellular Internet access. Performance will be limited by the capabilities of the phone and the cell tower to which it is connected.
- 33. Type of network infrastructure spans a physical area larger than a LAN but smaller than a WAN and is typically operated by a single entity such as a large organization
- 35. allows people to share files with each other without having to store and download them from a central server
