Difference between RAM and ROM.

`The difference between Ram and Rom are: RAM ROM RAM stands for Random Access Memory. ROM stands for Read Only Memory. Random Access Memory (RAM) is costly if compared to ROM. ROM is more inexpensive when compared to RAM. The data saved in RAM is utilized by the Central Processing Unit (CPU) to prepare current…

Difference between Input Unit and Output Unit.

`: The difference between Input unit and Output unit are: Input Unit Output Unit  Input is any data that is sent to the computer for processing.  Output is the result of processed data that we can see through some other devices. Input devices are controlled by the users. Output devices are controlled by  computers. It converts user-friendly…

Difference between data and information.

Data Information Data is a collection of facts Information puts those facts into context. Data are raw and unorganized Information is organized.. Data doesn’t depend on information. Information depends on data. Raw data alone is insufficient for decision making Information is sufficient for decision making Data typically comes in the form of graphs, numbers, figures,…
