Bandwidth refers to the amount of data that can be sent over a network or modem. Measured in “bps” or bits per second, bandwidth is a bit like a road and the bits are like cars on the road. A two-lane road can’t carry much traffic and is slow. A six-lane freeway is much faster.
A cache is a storage area that gives you speedy access to information you’ve recently used. If you’ve ever noticed that the second time you visit a website it seems to load faster, it’s probably because some of the information on the website has been ‘cached’ somewhere on your computer or in the cloud (see below).
The ‘cloud’ is the remote server or network of servers you connect with when using any number of internet services, including your email or social media sites. Free and paid services allow you to work or store data ‘in the cloud’ instead of on your personal computer.

When you purchase a computer, your sales assistant is bound to tell you how much ‘RAM’ (pronounced ram, like the sheep) the computer has. RAM stands for Random Access Memory.
