1000BaseT: 1000Mbps CSMA/CD Ethernet LAN that operates on Category 5e UTP/STP cabling and utilizes the star configuration. Most common network solution.

100BaseT: 100Mbps CSMA/CD ethernet LAN that operates on Category 5 UTP/STP cabling. Utilizes the star configuration.

10Base2: IEEE standard for baseband Ethernet at 10Mbps over RG-58 coax cable to a max distance of 185 meters. Also known as Thinnet, highly uncommon in modern network environments.

10Base5: IEEE standard for baseband Ethernet at 10Mbps over heavy coax cable for a maximum distance of 500 meters. Also called Thicknet, rarely seen in modern network environments.

10BaseT: 10Mbps (Megabits per second) CSMA/CD (Carrier Sense Multiple Access with Collision Detection) LAN that runs on Category 3 and better UTP/STP (unshielded twisted pair / shielded twisted pair) . . . View Full Definition

128K: Uncommon modem operating speed, rarely seen, the intended result of signal acceleration.

28.8K: Lowest end operating speed for modems as set by the FCC. Operates at 28.8 Kbps.

32-bit-16-bit: There are many advantages that 32 bit has over the 16 bit applications. 32 bit application have their own address space which creates a stable environment for a computer system. Whereas the . . . View Full Definition

56K: Most common modem (modulation/demodulation) speed. Generic term for modems that can receive data at 56Kbps (kilobits per second).

802.1: Standard defining Network Bridging. Bridges also known as Layer 2 Switches because they operate at the Data Link layer of the OSI model.

802.11a: Standard defining wireless networking that operates on the 5GHz band at a speed of 54Mbps. Shorter range than 802.11b/g standards.

802.11b: Standard defining wireless networking that operates on the 2.4Ghz band at the speed of 11Mbps.

802.11g: Standard defining wireless networking that operates on the 2.4Ghz band at the speed of 54Mbps.

802.11n: Standard defining wireless networking that improves upon prior standards by using Multiple Input Multiple Output (MIMO) technology to achieve data transmission speeds nearing 600Mbps. Utiliz . . . View Full Definition

802.15: Standard defining the Personal Area Network (PAN) and Wireless PAN, a network consisting of connected devices within a few meters of each other. Can include Bluetooth, Z-Wave, ZigBee, and US . . . View Full Definition

802.16: Standard defining Broadband Wireless Access, aka WiMAX technology.

802.2: Standard defining Logical Link Control (LLC), which provides flow and error control over the upper Data Link layer of the OSI model.

802.3: Standard defining wired Ethernet. Typically LAN technology with some WAN applications. Works on the Physical and Media Access Control (MAC) layers of the OSI model.
