  1. Bandwidth - term that describes the maximum speed at which data can be transmitted between two nodes on a network
  2. Broadband - often referred to as high-speed internet, refers to the type of connection that offers a means to connect to the internet with faster throughput
  3. 802.11 standard/Wi-Fi - the standard for wireless ethernet networks; wireless fidelity (WiFi)
  4. Cat 6 cable - commonly referred to as Cat 6, is a standardized cable for Gigabit Ethernet and other network physical layers that is backward compatible with the Category 5/5e and Category 3 cable standards.
  5. Client - a computer on which users accomplish tasks and make requests
  6. Client-server network - a network that uses a client computer and a server computer. the server is the computer that provides information or resources to the client computers as well as central administration for network functions such as printing
  7. Coaxial cable - media that consists of a single copper wire surrounded by a plastic jacket
  8. Data transfer rate/Bandwidth - the amount of digital data that is moved from one place to another in a given time
  9. Digital media receiver - A device that funnels multimedia content streamed from the Internet to a stereo or home theater system
  10. DSL/cable router - Digital subscriber line; A technology that significantly increases the digital capacity of ordinary telephone lines (the local loops) into the home or office. DSL speeds are based on the distance between the customer and telco central office.
  11. Ethernet network - The global standard for cabling computers together in a network. Ethernet uses cables to connect devices; however, its wireless counterpart is "Wi-Fi," and both wired and wireless operation is commonplace in companies and at home.
  12. Fiber-optic cable - media made up of plastic or glass fibers that transmit data at extremely fast speeds
  13. FiOS - a telecom service offered over fiber-optic lines
  14. Firewall - hardware or software solution that helps shield your network from intruders
  15. Firmware - Software instructions residing in non-volatile memory chips that hold their content without power. Firmware is found on computer motherboards to hold hardware settings and booting data and on myriad consumer electronics devices to hold the operating system or control program.
  16. Gigabit - a transmission technology based on the Ethernet frame format and protocol used in local area networks (LANs), provides a data rate of 1 billion bits per second
  17. HAN - internet ready, network ready
  18. Hacker - a person who uses computers to gain unauthorized access to data
  19. Home area network (HAN) - is a type of local area network with the purpose to facilitate communication among digital devices present inside or within the close vicinity of a home
  20. Hub- A device connected to several other devices.
  21. ISP- Where you can be able to connect to the internet.
  22. Local area network (LAN)- Is a computer network that interconnects computer within a certain area, such as a home or school.
  23. Media access control (MAC) address- Is a unique identifier assigned to network interfaces for communication on the physical network segment.
  24. Metropolitan area network (MAN)_ is a computer network larger than a local area network, covering an area of few city blocks, to the area of an entire city, including the surrounding areas.
  25. Multiple Input Multiple output(MIMO)- Is a method for multiplying the capacity of a radio link using multiple transmit and receive antennas to exploit multipath propagation.
  26. Network- connect as or operate with a network.
  27. Network adapter- Is a computer hardware component that connects a computer to a computer network.
  28. Network attached storage (NAS) device- A file server that connects to the network.
  29. Network architecture- Is the design of a communications network.
  30. Network interface card (NIC)- is a circuit board or card that is installed in a computer so that it can be connected to a network.
  31. Network navigation device- Units which are the last receiver or generate data are called hosts or data terminal equipment.
  32. Network operating system (NOS)- Refers to software that implements an operating system of some kind that is oriented to computer networking.
  33. Network-ready device- Refers to software designed to run in network.
  34. Node- Is a basic unit used in computer science.
  35. Packet- Is the unit of data that is routed between an origin and a destination on the internet or any other packet-switched network.
  36. Peer-to-peer (P2P) network- A network of computer configured to allow certain files and folders to be shared with everyone or with selected users.
  37. Piggybacking- is a wireless communications context, is the unauthorized access of a wireless LAN.
  38. Power-line network- Is one of the cheapest forms of home networking and has a low start-up cost and minimal IT workload.
  39. Repeater- installed on long cable runs to to amplify the signal.
  40. Router- a device that routes packets of data between two or more networks.
  41. Server- a computer that provides resources to other computers on a network.
  42. Service set identifier(SSID- a network name that wireless routers use to identify themselves.
  43. Switch- a device for transmitting data on a network. a switch makes decisions, based on the media access control address of the data, as to where the data is to be sent.
  44. Throughput- The actual speed of data transfer that is received. It’s usually less than the data transfer rate and is measured in megabits per second(Mbps).
  45. Transceiver- a device that can both transmit and receive communications, in particular a combined radio transmitter and receiver.
  46. Transmission media- the radio waves or the physical system(the cable) that transports data on a network.
  47. Twisted-pair cable- cables made of copper wire that are twisted around each other and are surrounded by a plastic jacket(such as traditional home phone wire)
  48. Unshielded twisted-pair (UTP) cable- the most popular transmission media option for Ethernet networks. UTP cable is composed of four pairs of wires that are twisted around each other to reduce electrical interference.
  49. WAN- a network made up of local area networks(LANs) connected over long distances.
  50. Wide area network (WAN)- a network made up of local area networks(LANs) connected over long distances.
  51. Wi-Fi- the 802.11 standard for wireless data transmissions established by the Institute of Electrical and Electronics Engineers(IEEE).
  52. Wired Ethernet network- a family of computer networking technologies for local area networks and metropolitan area networks
  53. Wireless access point (WAP)- gives wireless devices a sending and receiving connection point to the network.
  54. Wireless Ethernet network- The standard for wireless networking within a home or office. Also known as a "Wi-Fi" or "802.11" network, wireless Ethernet is the wireless counterpart to regular, wired Ethernet, which is also the standard for local networks
  55. Wireless network- any type of computer network that uses wireless data connections for connecting network nodes.
  56. Wireless network adapter- a client device inside a wireless network and is installed in a client computer.
  57. Wireless router/gateway- a device that performs the functions of a router but also includes the functions of a wireless access point.
