Storage devices and output devices
Answers
Answer:
Definition:
Like the input, the output device is also a peripheral and hardware device used to receive the result of the processing date that comes from its input. All computer or information system absolutely need output devices.
Output devices are also known as the way that the computer communicates with human.
Types of Output:
There are three principal types of output devices based on the way they deliver the output data:
Storage Devices:
There are primarily three types of storage a computer possess, first the primary storage, which is more popularly called simply memory; the secondary storage, which is more popularly referred to as simply storage, and finally the offline storage referred as movable storage.
Primary Storage:
Primary storage is where a computer stores data on a temporary basis so it can process the data. Think of primary storage as “short term memory”. Primary storage is a type of memory that is directly accessible to a computer processor and it is volatile because it is temporary in nature and is erased when the power is turned off.
The main primary storages are:
RAM (Random Access Memory)
ROM (Read Only Memory)
Data the computer is currently processing or data which the computer knows it is about to need for processing is stored in primary storage. Memory in primary storage can be accessed quickly by the CPU. Its storage capacity, however, is much smaller than what can be stored in secondary or tertiary storage. Computers need just enough primary storage to function and temporarily hold anticipated amounts of data for processing.
