Connecting to the Internet is a mine field of confusing terms and acronyms which makes the whole process more confusing than it needs to be. The following explanations will hopefully help make some sense out of that.
Bandwidth
In the context of computer networks and the Internet, bandwidth is the term used to describe the amount of data that can be transferred over the network or Internet connection. Internet access packages include varying amounts of data transfer, depending on the plan chosen. Bandwidth is usually sold in gigabytes and is cheaper in bulk
Connection Speed
The second main differentiator between Internet access packages is the speed at which data can travel over the network. Speeds are typically measured in how many kilobits (Kbps) or megabits (Mbps) of data can move over the network each second.
Speeds available in South Africa range from 384 Kbps upwards and the technology is improving all the time. A 384 Kbps Internet connection would be quite sufficient for a user or two wanting to browse the web and send and receive e-mail. A faster connection would be needed for an office network or if anyone was using the connection to download large data files such as YouTube videos or big graphics.
Shaped Bandwidth
Internet access packages offering shaped bandwidth are generally the cheapest because they prioritise data traffic concerned with viewing websites and downloading e-mail. Other Internet activity, including connecting to private networks and online gaming, receives a lower priority. Most user will be happy using shaped bandwidth.
Unshaped Bandwidth
Accounts offering unshaped bandwidth do not discriminate against any sort of network traffic and generally offer faster transfer speeds than their shaped cousins. They are, of course, more expensive than the shaped options. Many power users prefer unshaped bandwidth because of the faster speeds obtainable.
Local-only Bandwidth
Local-only bandwidth is, as far as I know, a purely South African phenomenon and it refers to traffic between computers located within the borders of the country. This bandwidth is by far the cheapest available and could be a viable choice in applications such as, for example, connecting to an office network from home. Many Internet service providers offer local-only bandwidth packages which generally include a small allowance of international traffic as well.
Uncapped Internet
These accounts in theory offer unlimited data transfer for a set amount every month. The deals usually sound very good but, at least in the South African context, there is almost always some sort of limit. These usually show up the fine print as “Fair Use” policies. In spite of this, however, they can still provide good value for money.
Capped Internet Accounts
These accounts include a set amount of data each month and generally provide faster data transfers. They sound less cost-effective than uncapped accounts but, because of the faster speeds, are often the better choice for business.
