A CD or DVD drive is a media device. Data is usually read from it, but data can also be sent to it if it has writing capabilities.
An interesting question. Typically, devices fall into a category of 'input' or 'output'. A monitor, for example, would universally be regarded as an output device. A keyboard, an input device. A platter, which I'm assuming is a hard drive platter and not a delicious halal meal, falls neatly into both catgeories. It is an input device when data is being read from it, and an output device where data is being read to it.
No CD-ROM means Compact Disc Read-Only Memory. CD-ROM is an input device. However, CD-RW (Compact Disc Read Write) is both a input and output device.
input device
A: It is a device or meter that read frequency as an input and display its value
output device
yes its input but somewhere i had read its both input and output ,but i cannt understand why its output . regards Hashaam zahid hashaamzahid3@gmail.com
List of the inputs and built-in effects read in the manual.
Pen drive is an Removable Device. It is use to File sharing. Easy to Read and Write files. Pen Drive is not consider as an Input/Output Device.
input
I would say that a CD-ROM is a form of input, as it is "read only memory" and the data on it can only be read, but not written to. If you're talking about CD-R/CD+R drives, then those would be considered both input and output, as it can read from a CD, and writes to CD.
In Java, System.in refers to the standard input stream (stdin). System.in is an instance of InputStream, which has a basic read method that allows you to read in one byte of data at a time. Quick example: System.out.println(System.in.read()); //User inputs "A", output is 65 Because the functionality of InputStream is so limited, Java offers more complex classes that can deal with input. Scanner is often used, which allows you to easily iterate through numerical input, entire lines of input, and user defined patterns. Another example with Scanner: Scanner sc = new Scanner(System.in); System.out.println(sc.nextLine()); //User inputs "Hello World", output is "Hello World" Scanner has many other methods that are best left to a separate question. It is worth noting that when you interact with System.in you need to handle possible IOExceptions.
