4.Client - (in a network) a desktop computer or workstation that is capable of obtaining information and applications from a server.

5.Client-server network - A host is any computer connected to a network.

6.Coaxial cable - a transmission line that consists of a tube of electrically conducting material surrounding a central conductor held in place by insulators and that is used to transmit telegraph, telephone, and television signals.

7.Data transfer rate/Bandwidth - In computing, bandwidth is the bit-rate of available or consumed information capacity expressed typically in metric multiples of bits per second.

8.Digital media receiver - are home entertainment consumer electronics devices that can connect to a home network to stream digital media (such as music, pictures, or video).

9.DSL/cable router - A device that provides access to the Internet for multiple computers. It typically includes a network switch with four or more Ethernet ports for wired connections to desktop and laptop computers.

11. Ethernet network - Ethernet is the most widely-installed local area network ( LAN) technology.

12. Fiber-optic cable- is used by many telecommunications companies to transmit telephone signals, Internet communication, and cable television signals.

13. FiOS-is a fiber to the premises (FTTP) telecommunications service offered by Verizon to consumers in the United States.

14. Firewall-a part of a computer system or network that is designed to block unauthorized access while permitting outward communication

15. Firmware-permanent software programmed into a read-only memory

16. Gigabit-a unit of information equal to one billion (109) or, strictly, 230 bits

17. HAN - Home Area Network

18. Hacker - Someone who finds a loophole into a system to gather information.

19. Home area network (HAN) -A home network or 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 common connection point for devices in a network. Hubs are commonly used to connect segments of a LAN.

21. ISP- is an organization that provides services for accessing, using, or participating in the Internet

22. Local area network (LAN)-is a computer network that interconnects computers within a limited area such as a home, school, computer laboratory, or office building, using network media.

23. Media access control (MAC) address-a unique identifier assigned to network interfaces for communications on the physical network segment.

24. Metropolitan area network (MAN)-is a large computer network that spans a metropolitan area or campus.

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 - A network is a group of two or more computer systems linked together.

27. Network adapter - Hardware that is installed into a computer system to be able to use a network.

28. Network attached storage (NAS) device- is file-level computer data storage server connected to a computer network providing data access to a heterogeneous group of clients.

29. Network architecture-is the design of a communications network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation

30. Network interface card (NIC)- is a computer hardware component that connects a computer to a computer network

31. Network navigation device-Device that helps to make the flow of data possible and enables the transmission of data

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- It implies that multiple users can share databases without conflict.

34. Node-a piece of equipment, such as a PC or peripheral, attached to a network

35. Packet-a block of data transmitted across a network

36. Peer-to-peer (P2P) network-network of computers configured to allow certain files and folders to be shared with everyone or with selected users.

37. Piggybacking-mount on or attach to (an existing object or system).

38. Power-line network- is one of the cheapest forms of home networking and has a low startup cost and minimal IT workload.

39. Repeater-a device for the automatic retransmission or amplification of an electrically transmitted message.

40. Router-a power tool with a shaped cutter, used in carpentry for making grooves for joints, decorative moldings, etc.

41. Server-a computer or computer program that manages access to a centralized resource or service in a network.

42. Service set identifier (SSID)-is a case sensitive, 32 alphanumeric character unique identifier attached to the header of packets sent over a wireless local-area network (WLAN) that acts as a password when a mobile device tries to connect to the basic service set

43. Switch - In networks, a device that filters and forwards packets between LAN segments.

44. Throughput - In computer technology, throughput is the amount of work that a computer can do in a given time period.

45. Transceiver - A transceiver is a combination transmitter/receiver in a single package.

46. Transmission media - Describes the type of physical system used to carry a communication signal from one system to another. Examples of transmission media include twisted-pair cable, coaxial cable, and fiber optic cable.

47. Twisted-pair cable - A type of cable that consists of two independently insulated wires twisted around one another.

48. Unshielded twisted-pair (UTP) cable - a popular type of cable that consists of two unshielded wires twisted around each other. Due to its low cost, UTP cabling is used extensively for local-area networks (LANs) and telephone connections.

49. WAN- Wide Area Network

50. Wide area network (WAN)-is a network that covers a broad area

51. Wi-Fi-a facility allowing computers, smartphones, or other devices to connect to the Internet or communicate with one another wirelessly within a particular area.
