Write a note on modem?
modemModem stands for modulation and demodulation. Modem is device that converts digital signal into analog and analog signal into digital. Modem sends and received data from one computer to another through telephone lines. The sending and receiving computers both must have modems.The process of converting digital signal into analog signal is called modulation computer store data in digital form. Since a modem transmits data using telephone lines. So it is converted from digital to analog from.The process of converting analog signal into digital signal is called demodulation. The modem on receiving computer receives data in analog form. The incoming analog data id converted back into digital format to be used by computer.Features of ModemSome important features of modem are as follows:1. Speed: speed is the rate at which the modem can send data in bps. Typically modem speeds are 300 bps to 56bps.2. Self- Testing: Modem can teat the digital connection with computer. It can also test analog connection with remote modem.3. Voice over Data: Modem provides the facility of voice conversation while data is being transmitted. Both the source and destination modems should have this feature.4. Error Control: Modem use different methods to control errors for transmitted data.Different types of modems :Different types of modems in terms of physical size and shape are as follows:External ModemExternal modem is attached to the system unit as an external device through telephone line. It is connected to the telephone wall jack by another cable. External modem is connected to computer using serial cable to COM1 or COM2 port. It requires external power supply. It is easy to setup. External modem is expensive.Internal ModemInternal modem is a circuit board that is inserted into an expansion slot on the motherboard. Internal modem cannot be moved from one computer to anther easily. It is difficult to setup than other types of modem. It is less expensive than external modem.Wireless ModemWireless modem transmits the data signals through air instead of cable. It also known as radio-frequency modem. It is designed to work with cellular technology and wireless local area networks.
How do electronic document management systems make storing documents easier?
Electronic document management systems allow documents to be stored in a more convenient and paperless digital form. In their digital form, these documents are easily searchable and recoverable as well as more cost effective, as firms do not have to waste money on filing cabinets and folders.
Is the internet considered a form of electronic data interchange?
The internet definitely is an example of electronic data interchange because information is sent from one computer to the next. And all of the systems are connected created one big electronic data network.
In what form geothermal energy is stored?

How a text is converted into digital data?
There are several ways that written text is converted into digital form or data. 1. Word processing is a term to describe how words are typed into a computer application and then converted into fancier looking text. WP data can then be printed by the computer through a LASER printer or the data can be stored on the computer or even sent in digital form from one computer to another computer / printer / storage device somewhere else on the planet. 2. Scanning a written word book through a convertor or scanner uses simmilar technology to a photo copier to input the written words into digital form
What is digitally stored data?

What is binary form in computer?
First we have to know that "in which form data is stored on computer is logical" (may be the two stable states of a flip-flop, two positions of an electrical switch, two distinct voltage or current levels allowed by a circuit) According to computers Binary form means 0 or 1, through which data in computer is stored to represented
Can a computer process information in both digital and analog formats?
Yes. Digital processing is the most commonly used form as the computer works with bits and byte. The most popular example of analog processing of data is ECG, where the signal are in analog form.
Processed data that can be used immediately or stored in computer-usable form later use is called what?
Input
What is tunage?
A quantity of tunes stored in digital form.
What type information system would be recognized by digital system?
A digital system can recognize digital data i.e. data only in form of 0 & 1, if data is not in digital form we have to convert it using analog to digital converters.
