Sep 25, 2016 ... A printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper. Printers vary in size, speed, sophistication, and cost. In general, more expensive printers are used for higher-resolution color printing.

A projector or image projector is an optical device that projects an image (or moving images) onto a surface, commonly a projection screen. Most projectors create an image by shining a light through a small transparent lens, but some newer types of projectors can project the image directly, by using lasers.

ROM stores data and instructions permanently. When the power is turned off, the instructions stored in ROM are not lost. That is the reason ROM is called non-volatile memory.

Types of ROM

1. PROM: It stands for Programmable Read Only Memory. This form of ROM is initially blank. If there is an error it cannot be fixed... it becomes unusable.

2. EPROM: It stands for Erasable Programmable Read Only Memory. This form of ROM is also initially blank. In EPROM chip can be changed and new data can also be added. When EPROM is in use, its contents can only be read.

3. EEPROM: This stands for Electrically Erasable Programmable Read Only Memory. This kind of ROM can be written or changed with the help of electrical devices. So data stored in this type of ROM chip can be easily modified.

The retention of retrievable data on a computer or other electronic system; memory.
Examples:
-Solid State Drive: SSDs have no moving mechanical components. This distinguishes them from traditional electromechanical magnetic disks such as hard disks.
-Hard Disk: a high-capacity, self-contained storage device containing a read-write mechanism plus one or more hard disks, inside a sealed unit.
-USB:  the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices.
