Short for "second generation", 2G is the cellular technology that preceded 3G, 4G and 5G. 2G technology was the first that supported data communications such as mobile internet and MMS.

Short for "third generation", 3G is the cellular technology that came after 2G and preceded 4G and 5G. 

Short for "fourth generation", 4G is the cellular technology that came after 3G and preceded 5G. It offers better performance than its predecessors, and at the time of writing, is the most common cellular technology used. 

Short for "fifth generation", 5G is the next step in the evolution of cellular technology, but is not yet readily available. Though there have been other trials by other telcos, the only companies in the world offering 5G for carriers (at the time of writing) are Huwai, ZTE, Samsung and Ericsson. It is designed to be faster and more efficient than its predecessors, thereby making it a viable option for the Internet of Things (see below).

ADSL stands for Asymmetric Digital Subscriber Line, and it is a type of internet connection which uses copper phone lines to transmit data. ADSL has now been superseded by ADSL2+ - however for customers who cannot get ADSL2+, they may be able to access ADSL. ADSL uses the copper lines and can get speeds up to 8Mpbs.

ADSL2+ is another type of internet connection which uses copper phone lines to transmit data. ADSL2 superseded ADSL, and ADSL2+ superseded ADSL2; however, all versions are currently still available. Like their predecessors, ADSL2 and ADSL2+ both use copper phone lines, which are already ubiquitous, which is handy if you’re moving to a property that is not yet equipped for the NBN (see below). However, eventually all ADSL technologies will be replaced by the NBN.

Mbps that stands for Megabits Per Second, and it's how we measure download and upload speeds. A megabit is equal to one million bits. Transmissions across computer networks and very commonly measured in Mbps, and it is how we measure broadband speed. The higher the Mbps, the quicker your internet will work. 

MBps (with an upper-case B) is distinct from Mbps (with a lower-case b) in that it stands for Megabytes Per Second. It is used in reference to things such as file sizes. 

Short for Multimedia Messaging Service, MMS is the system that enables mobile phones to send and recieve colour photos, sound clips, and text messages. 

Mobile Broadband refers to any version of wireless internet access, typically through a mobile phone, laptop, tablet, or dongle (see above).  

A modem is a piece of hardware that converts and transmits data between differnent computers and devices. The word is a portmanteau of modulator-demodulator. They can cost anywhere between $50 and $400, but are sometimes included for free as an enticement for signing with a Lock In Contract (see above). 

A Naked DSL, also known as a standalone or a dry loop, is an old ADSL2 internet connection where the activeness of a phone line has been stripped, hence the “naked” title.
