2. Data Storage
Raw data often enters the computer system by means of an input device such as a keyboard or scanner. For example you enter text into a wordprocessing application with a keyboard.
The CPU then processes data and then one or two things happen - the data is sent directly to an output device such as the computer monitor and / or it is stored for later use.
Data is normally stored as a named file on whatever storage device is to be used.
Exactly how the data is stored depends on a number of factors such as:
Capacity |
- the amount of data to be stored / size of the file |
Speed |
- how quickly the user needs to be able to access the data from the storage device |
Portability |
- whether the data needs to be moved from one place to another such as from home to school |
Durability |
- How long the storage media can reasonably be expected to last. |
Reliability |
- whether the data can always be accessed reliably and in the format in which it was saved. |
