Chapter 7 - Networking Flashcards
4G
The latest mobile communication standard with faster data transfer rates than 3G
Backward compatibility
The accommodation of current devices being able to use previously issued software standards in addition to the current standards
Bandwidth
The max speed at which data can be transmitted between two nodes on a network
- usually measured in megabits per second
Broadband
A high speed Internet connection such as a cable, satellite or digital subscriber line
Cable Internet
A broadband service that transmits data over coaxial cables
Cat 6 cable
A UTP cable type that provides more than 1 Gb/s of throughput
Coaxial cable
A single copper wire surrounded by layers of plastic insulation, metal sheathing, and a plastic jacket
- used mainly in cable television and cable Internet service
Data transfer rate
The max speed at which data can be transmitted between two nodes on a network
- measured in megabits of gigabits per second
Digital subscriber line (DSL)
A type of connection that uses telephone lines to connect to the Internet and that allows both phone and data transmissions to share the same line
Ethernet network
A network that uses the Ethernet protocol as the means by which the nodes on the network communicate
Fibre-Optic cable
A cable that transmits data at close to the speed of light along glass or plastic fibres
Fibre-Optic service
Internet access that is enabled by transmitting data at the speed of light through glass or plastic fibres
Firmware
System software that controls hardware devices
Gigabit Ethernet
The most commonly used wired Ethernet standard deployed in devices designed for home networks
- provides bandwidth of up to 1 Gbps
Home area network (HAN)
A network located in a home that is used to connect all of its digital devices
Home network server
A device designed to store media, share media across the network and back up files on computers connected to a home network
Internet of Things (IoT)
The interconnection of uniquely identifiable embedded computing devices that transfer data over a network without requiring human-to-human or human-to-computer interaction
Internet service provider (ISP)
A company that specialized in providing internet access
- may be specialized like Juno
- may be companies that provide other services in addition to internet like phone and cable
Local area network (LAN)
A network in which the nodes are located within a small geographic area
Metropolitan area network (MAN)
A wide area network that links users in a specific geographic area (like within a city or country)
Mobile broadband
Connection to the Internet through the same cellular network that cell phones use to get 3 or 4G internet access
Mobile hotspot
Devices that enable you to connect more than one device to the Internet and require access to a data plan
Modem
A device that connects a network to the Internet
Network
A group of two or more computers (or nodes) that are configured to share information and resources such as printers, files and databases
Network adapter
A device that enables the computer (or peripherals) to communicate with the network using a common data communication language or protocol
Network administration
Involves tasks such as installing new computers and devices, monitoring the network for efficient performance, updating and installing new software on the network and configuring proper security
Network architecture
The design of a computer network - includes both physical and logical design
Network-attached storage (NAS) device
A specialized computing device designed to store and manage network data
Network interface card (NIC)
An expansion card that enables a computer to connect to other computers or to a cable modem to facilitate high-speed Internet connection
Network navigation device
A device on a network such as a router or switch that moves data signals around the network
Network operating system (NOS)
Software that handles requests for information, Internet access and the use of peripherals for the rest of the network node, providing the services necessary for the computer on the network to communicate
Network-ready device
A device (printer or external hard drive) that can be attached directly to a network instead of needing to attach to a computer on the network
Node
A device connected to a network such as a computer, peripheral or communications device (like a modem)
Packet
A small segment of data that is bundled for sending over transmission media. Each packet contains the address of the computer or peripheral device to which it is being sent
Peer-to-peer network (P2P)
A network in which each node connected to the network can communicate directly with every other node on the network
Personal area network (PAN)
A network used for communication among devices close to one person, such as smartphones, laptops and tablets, using wireless technologies such as bluetooth
Piggybacking
The process of connecting to a wireless network without the permission of the network owner
Router
A device that routes packets of data between two or more networks
Satellite Internet
A way to connect to the Internet using a small satellite dish which is placed outside the home and is connected to a computer with a coaxial cable. Satellite company sends the data to a satellite orbiting the Earth and the satellite in turn sends the data back to the satellite dish and to the computer
Service set identifier (SSID)
A network name that wireless routers use to identify themselves
Smart home
A house in which devices and appliances are automated or controlled by apps
Throughput
The actual speed of data transfer that is achieved
- usually less than the data transfer rate and measured un megabits per second
Transmission media
The radio waves or the physical system (cable) that transports data on a network
Twisted-pair cable
Cables made of copper wires that are twisted around each other and are surrounded by a plastic jack
- traditional home phone wire
Unshielded twisted-pair cable (UTP)
The most popular transmission media option for Ethernet networks. Cable is composed of four pairs of wires that are twisted around each other to reduce electrical interference
Wide area network (WAN)
A network made up of local area networks connected over long distances
Wireless fidelity (WiFi)
The 802.11 standard for wireless data transmission established by the Institute of Electrical and Electronics Engineers (IEEE)
Wireless range extender
A device that amplifies your wireless signal to get it out to parts of your home that are experiencing poor connectivity
