- 802.11ac is a wireless networking standard in the 802.11 family (which is marketed under the brand

802.11ac
name Wi-Fi), developed in the IEEE Standards Association process, providing high-throughput wireless local
area networks (WLANs) on the 5 GHz band.
802.11n - 802.11n builds upon previous 802.11 standards by adding MIMO (multiple-input multiple-output).

MIMO uses multiple transmitter and receiver antennas to allow for increased data throughput via spatial
multiplexing and increased range by exploiting the spatial diversity, perhaps through coding schemes like
Alamouti coding. The Enhanced Wireless Consortium (EWC) [3] was formed to help accelerate the IEEE 802.11n
development process and promote a technology specification for interoperability of next-generation wireless local
area networking (WLAN) products.
- 802.11a was an amendment to the IEEE 802.11 wireless local network specifications that defined

802.11a
requirements for an orthogonal frequency division multiplexing (OFDM) communication system. It was originally
designed to support wireless communication in the unlicensed national information infrastructure (U-NII) bands
(in the 5–6 GHz frequency range) as regulated in the United States by the Code of Federal Regulations, Title 47,
Section 15.407.
- The 802.11b standard specifies a wireless networking at 11 Mbps using direct-sequence spread-spectrum (DSSS)

802.11b
technology and operating in the unlicensed radio spectrum at 2.4GHz, and WEP encryption for security. 802.11b networks
are also referred to as Wi-Fi networks.
- specification for wireless networking at 54 Mbps using direct-sequence spread-spectrum (DSSS)

802.11g
technology, using OFDM modulation and operating in the unlicensed radio spectrum at 2.4GHz, and backward
compatibility with IEEE 802.11b devices, and WEP encryption for security.
DDNS (Dynamic Domain Name System)

dynamic Internet IP Address.
DHCP (Dynamic Host Configuration Protocol)

parameters for the all the PC(s) that are connected to a DHCP server.
DMZ (Demilitarized Zone)

special-purpose service such as Internet gaming or videoconferencing.
DNS (Domain Name System)

- A descriptive name for an address or group of addresses on the Internet.

Domain Name
DSL (Digital Subscriber Line)

phone lines.
MTU (Maximum Transmission Unit)

- The capability of assigning a fixed host and domain name to a
- A protocol that automatically configure the TCP/IP
- A Demilitarized Zone allows one local host to be exposed to the Internet for a
- An Internet Service that translates the names of websites into IP addresses.
- A technology that allows data to be sent or received over existing traditional
- The size in bytes of the largest packet that can be transmitted.
