Any device, such as a workstation, laptop, or tablet, that is used to access a network.
Provides resources to network users, including email, web pages or files.
A Layer 1 device that does not perform any inspection of traffic. This device simply receives traffic in a port and repeats that traffic out all other ports.
A Layer 2 device that makes its forwarding decisions based on the destination MAC address.
A Layer 3 device that makes forwarding devices based on Internet Protocol addressing.
Can operate at both Layer 2 and Layer 3. Also called a Layer 3 switch, this is a device that can switch traffic within the LAN and forward packets between subnets.
This can be copper cabling, fiber-optic cabling, or radio waves. Media varies in its cost, bandwidth capacity, and distance limitation.
Short for modulator/demodulator. This device converts the digital signal generated by a computer into analog signals that can travel over phone lines.
A digital modem that uses high-speed DSL or cable Internet service. Both operate in a similar manner to the analog modem, but use higher frequencies for transmission speeds.
A network device with a built-in antenna, transmitter, and adapter that provides a connection between WLANs and a wired Ethernet LAN.
Private Branch Exchange is a privately owned telephone switch traditionally used in corporate environments.
Session Initiation Protocol is a VoIP signaling protocol used to set up, maintain and tear down VoIP phone calls.
Real-time Transport Protocol carries voice (and interactive video), but does not go through call agent - goes straight to gateway.
Analyzes number dialed from VoIP phone to determine how to route the call to destination.
Maps hostname to IPv4 address
Maps hostname to IPv6 address
Canonical name record - is an alias of an existing record, thus allowing multiple DNS records to map to the same IP address
Mail exchange record maps a domain name to an email server for that domain
Pointer record points to a canonical name. A PTR record is commonly used for performing reverse DNS lookup.
A start of authority record provides information about a DNS zone, such as email contact information for the zone's administrator, the zone's primary name server and various refresh timers
Integrated Service Digital Network is a circuit-switched network. Classified as either Basic Rate Interface (BRI) of two 64kbps channels, or Primary Rate Interface (PRI) of 23 64kpbs [equivalent to a T1 circuit].
Analog connection over PSTN limited to 53.3 Kbps down / 48.0 Kbps up
Point to Point Protocol - Layer 2 protocol used on dedicated leased lines. It can carry layer 3 protocols (IPv4 and IPv6).
Password Authentication Protocol - one way authentication with passwords sent in clear text.
Challenge Handshake Authentication Protocol - One-way authentication using 3-way handshake (challenge, response, acceptance). Passwords not sent across the link.
Microsoft enhanced version of CHAP. Includes 2-way authentication.
Synchronous Optical Network - Fiber-optic WAN technology that delivers voice, video and data a speeds starting at 51.84 Mbps (OC-1).
Dense wavelength-division multiplexing
Course wavelength-division multiplexing
Optical carrier 1 level = 51.84Mbps
3 times an OC-1 connection = 155.52
