Web Apps are custom built software (an application) that doesn’t have to be installed but can be run from any internet browser on any computer. Web Apps are most useful when a distributed group of people need access to the same information or a small group of people need access to information when away from their desk. Web Apps are custom built bits of code that carry out a particular job. They can be large or small, simple or very complex. They are generally built to take advantage of the “cloud”. The “cloud” is a big lump of storage space somewhere on the internet.
