Most broadband consumers do not know much data they will use when they are carrying out their online activities. Below is a helpful key that can help you approximate how much data you would have consumed per transaction:

• A single text character = 1 Byte
• A typewritten page = 2 Kilobytes
• A low resolution photograph = 100 Kilobytes
• A high resolution photograph = 2 Megabytes
• The contents of a CD-ROM = 700 Megabytes
• The contents of a DVD = 4.7 Gigabytes

Data units

The following unit measurements represent how data/ information is measured on a computer. The list starts with the smallest unit:

• Bit - 8 Bits= 1Byte
• Byte - 1024 Bytes = 1 Kilobyte
• Megabyte - 1024 Kilobytes = 1 Megabyte
• Gigabyte - 1024 megabytes = 1Gigabyte
