- Describe the main systems for sharing information through networked computers.
- Define cloud computing and identify its advantages and disadvantages.
Once it’s grown beyond just a handful of employees, an organization needs a way of sharing information. Imagine a flower shop with twenty employees. The person who takes phone orders needs access to the store’s customer list, as do the delivery person and the bookkeeper. Now, the store may have one computer and everyone could share it. It’s more likely, however, that there are a number of computers (several for salespeople, one for delivery, and one for bookkeeping). In this case, everyone needs to be sure that customer records have been updated on all computers every time that a change is required.
