In this final installment, we talk about Bandwidth.
What is Bandwidth?
Bandwidth is often interpreted to be the speed that data passes through a given circuit. It’s commonly measured in Kilo (thousand), Mega (Million) or Giga (Billion) bits per second.
If your internet provider says that they provide 3 Mega bits per second, this means that the line has a theoretical transport capacity 3 million bits per second.
Does this mean that data will pass this fast? Usually not. Many other limitations can cause average data transport speeds to be less than the theoretical limit.
The key factor to keep in mind for you the IT Manager is that bandwidth is a scarce commodity. And while it’s been getting cheaper in recent years, it still costs money. And the more bandwidth you need, the more you’re going to pay.
