Bytes and bits

Bytes are a unit of memory or size of data. Usually you would count them in megabytes or gigabytes. These Bytes are stored in a series of 'Bits' (approx eights bytes to a bit), and these Bits are what measures the speed of your internet connection. For ease, think of bytes as the weight of your data, and the bits as the length it travels, thus, Megabits per second. This is why your data limit is valued by bytes (the weight of the data), but your broadband speed by bits (length travelled).


Cabinet / Street Cabinet / Green Cabinet
