Advantage of digital signal?
Higher immunity to noise, storage of digital signal is cheap and easy, its representation is only using two levels as opposed to infinite levels for analog
What is the term for a device that converts digital data from a computer into analog signals and back again?
The devices are known very simply as analog to digital converters and digital to analog converters. They are frequently shorted to A-D and D-A converters. A complete analog to digital converter will not only convert the analog signal into a set of numbers, it will also format the digital data ready to deliver to the next step in the signal chain. In television, this means generating a fairly complex stream of data that will carry not only the picture but audio and other data as well. Digital to analog converters reverse the process and use the incoming data to generate an analog signal. In television, well know examples are the digital set top boxes. They receive digital data from an antenna and convert the numbers into analog audio and video signals.
What is unshielded cable?
Unshielded cable is any metal cable that is not enclosed in a protective sheathing. Unprotected cables are not meant to carry an electrical charge. Another reason for applying sheathing around a cable is to protect it from the weather; such as guardrails etc.
Advantages and disadvantages of digital jewellery?
THE ADVANTAGES ARE 1) IT PROVIDES SECURITY for example JAVA RING is used to lock or unlock doors or computers...as we use passwords and keys to lock our doors and computers we dont need to remember all those passwords and carry all those keys.SO java ring is designed to provide security 2)AS COMPUTING DEVICES are embedded it is not neccessary to carry CELLS r COMPUTERS...hence it is easy to carry everywhere
Full form of MODEM?
modulation and demodulation
What cells carry electrical pulses?
neurons
What media is used to carry electrical pulses that represents digital data?
Copper cable is the answer. Fiber Optic transmit using light and radio is frequency while wireless is wireless.

What does not carry an electrical current?
An electrical insulator.
Thin glass cable used to carry pulses of light?
Fiber Optic cables
Does a T line carry digital data over twisted pair wires?
Yes it does. It will carry digital data as well as voice signals.
Which types of signals are carried over a DSL cable?
DSL is carried over a phone line. Yet it caries digital signals. the telephone company has to limit the bandwidth of the analog voice on the lines. So DSL is able to use the unused portion of the bandwidth to transmit digital data. hope that helps -------------------------------------------------------------------------------------------------------- According to Cisco : Network devices link together using a variety of connections: * Copper cabling - Uses electrical signals to transmit data between devices * Fiber-optic cabling - Uses glass or plastic wire, also called fiber, to carry information as light pulses * Wireless connection - Uses radio signals, infrared technology (laser), or satellite transmissions. so your answer would be electrical signals.
Do victims struck by lightning carry an electrical charge and should not be touched?
False! They carry no electrical charge and should be attended to immediately!
How do electromagnetic waves carry sound as electrical signals?
The electromagnetic wave is "modulated" (changed) to represent the signal. For example, in AM (amplitude modulation), the strength (amplitude) of the wave is increased or decreased, according to the signal.
