Essentials Of Networking Flashcards
Any computing device connected to a network
Host
Your computer
Local Host
Not your computer
Remote Host
A remote computer that stores the files that make up a Web site. Used server programs to store and share data
Web Server
Two popular Web server programs
Apache HTTP Server and Microsoft Internet Information Services (IIS)
Computer that has enabled a printer-sharing program built into Windows so that other computers on the network can use the printer
Print Server
A networked host that enables you to access a bunch of files and folders
File Server
The networked host you use to access email messages
Mail Server
Expansion card or motherboard interface that enables a PC to connect to a network via a network cable. A wireless one enables connection via radio waves rather than a physical cable
Network Interface Controllers (NICs)
Unique 48-bit address assigned to each network card. IEEE assigns blocks of possible addresses to various NIC manufacturers to help ensure that the address is always unique. The Data Link Layer of the OSI model uses these to locate machines
Media Access Control (MAC) address
Name coined by Xerox for the first standard of network cabling and protocols that define everything necessary to get data from one computer to another. Since its inception, it has gone through hundreds of improvements and even forms the basis of wireless networking signals
Ethernet
Improvement in Ethernet in areas such as speed, signaling, and cabling
Ethernet Flavors
Ethernet cabling system designed to run at 10 Mbps on twisted pair cabling
10BaseT
Ethernet cabling system designed to run at 100 Mbps on twisted pair cabling. Also called Fast Ethernet
100BaseT
Ethernet cabling system designed to run at 1000 Mbps on twisted pair cabling. Also called Gigabit Ethernet
1000BaseT
A hybrid network topology where the computers all connect to a central bus - a switch - and have a layout resembling a star
Star Bus Topology
Device that filters and forwards traffic based on some criteria. A bridge and router are both examples of them. “Smart” repeater, they memorize the MAC addresses of all the connected devices and only send out repeated signals to the correct host
Network Switch
Electronic device that sits at the center of a star bus topology network, providing a common point for the connection of network devices. “Stupid” repeater, anything sent in one port automatically went out to all the other connected ports
Hub
The capacity of a network to transmit a given amount of data during a given period
Bandwidth
The connection between a computer and a switch. Most cable types, limited to 100 meters or less
Segment
The specified cabling for 10/100/1000BaseT and is the predominant cabling system used today. Consists of AWG-22-26 gauge wire twisted together into color-coded pairs. Each wire is individually insulated and encased as a group in a common jacket
Unshielded Twisted Pair (UTP) cabling
Standard telephone line
Cat1
Designed for 10-Mbps networks; a variant that used all four pairs of wires and supports 100-Mbps
Cat3
Designed for 100-Mbps networks
Cat5
Enhanced to handle 1000-Mbps networks
Cat5e
Supports 1000-Mbps networks at 100-meter segments; 10-Gbps networks up to 55-meters
Cat6
