 Fourth Generation. 4G refers to the third generation of mobile telephony technology. 

 A set of WLAN communication standards in the 2.4, 3.6 and 5 GHz frequency 

bands. 
Broadband: 

High-capacity high-speed, transmission channel with a wider bandwidth than 

conventional modem lines. Broadband channels can carry video, voice, and data simultaneously. 
DHCP:

 Dynamic Host Configuration Protocol. Software found in servers and routers that 

automatically assigns temporary IP addresses to clients logging into an IP network. 
DHCP Server:

 A server or service with a server that assigns IP addresses. 

 A hardware or software boundary that protects a network or single computer from 

unwanted outside traffic. 
Firmware:

 A computer program embedded in an electronic device. Firmware usually contains 

operating code for the device. 
Hotspot: 

A Wi-Fi (802.11) access point or the area covered by an access point. Used for 

connecting to the Internet. 
HTTP:

 Hype r t ex t Tra n s f e r Pr o t o c o l. An application-level protocol for accessing the 

World Wide Web over the Internet. 
IEEE:

 Institute of Electrical and Electronics Engineers. An international technical/professional 

society that promotes standardization in technical disciplines. 
LAN:

 Local Area Network. A type of network that lets a group of computers, all in close 

proximity (such as inside an office building), communicate with one another. It does not use 
common carrier circuits though it can have gateways or bridges to other public or private 
networks. 
MAC Address:

 Media Access Control. A number that uniquely identifies each network 

hardware device. MAC addresses are 12-digit hexadecimal numbers. This is also known as the 
physical or hardware address. 
Port:

 A virtual data connection used by programs to exchange data. It is the endpoint in a logical 

connection. The port is specified by the port number. 
Port Forwarding:

 A process that allows remote devices to connect to a specific computer within 

a private LAN. 
Port Number: 

A 16-bit number used by the TCP and UDP protocols to direct traffic on a 

TCP/IP host. Certain port numbers are standard for common applications. 
Protocol:

 A standard that enables connection, communication, and data transfer between 

computing endpoints. 
Router: 

A device that directs traffic from one network to another. 

 Subscriber Identification Module. Found in GSM network technology, the SIM is a card 

containing identification information for the subscriber and their account. The SIM card can be 
moved to different devices. 
SSID: 

Service Set IDentifier. The name assigned to a Wi-Fi network. 

Transmission Control Protocol/Internet Protocol. The set of communications protocols 

used for the Internet and other similar networks. 
USB:

 Universal Serial Bus. A connection type for computing device peripherals such as a printer, 

mobile device, etc. 
VPN: 

Virtual Private Network. A way to communicate through a dedicated server securely to a 

corporate network over the Internet. 
WAN:

 Wide Area Network. A public network that extends beyond architectural, geographical, 

or political boundaries (unlike a LAN, which is usually a private network located within a room, 
building, or other limited area). 
WEP:

 Wired Equivalent Privacy. An IEEE standard security protocol for 802.11 networks. 

Superseded by WPA and WPA2.
