Communications and Networks Which of the following terms is an electrical disturbance that can degrade communications? The amount of data, instructions, and information that can travel over a communications channel sometimes is called which of the following? Bandwidth. Which of the following is true of DSL? What do you call the amount of data instruction and information that can travel over transmission
media? bandwidth. Amount of data/instructions/information that can travel over transmission media. body area network. Which of the following refers to any type of hardware capable of transmitting data instructions and information between a sending device and a receiving device? A communications device is any type of hardware capable of transmitting data, instructions, and information between a sending device and a receiving device. One type of
communications device that connects a communications channel to a sending or receiving device such as a com- puter is a modem. Which of the following is a LAN that uses no physical wires? BLAN. WLAN. Wireless LAN What are the different types of electrical
disturbances?
The common electrical disturbances that you encounter at your home (but might not know what the disturbance is exactly called) are: POWER SURGE A surge is a condition when there is a sudden increase in the voltage level above the designated or say normal level. How can electrical disturbances be prevented or prevented? The electrical disturbances sometime cause heavy damage and loss of property. But by installing the correct and effective preventive measure electrical devices can be protected in many such conditions. What to do about interference with TV signals?If you cannot determine the source of the electrical interference, contact the customer service department of your local power company. Most power companies will investigate the problem and take steps to correct it. What causes interference with a cell phone signal?Interference may prevent reception altogether, may cause only a temporary loss of a signal, or may affect the quality of the sound or picture produced by your equipment. The two most common causes of interference are transmitters and electrical equipment.

What do you call the amount of data instructions and information that can travel over transmission media?bandwidth. The amount of data, instructions, and information that can travel over a communications channel. Bluetooth. Network standard, specifically a protocol, that defines how two Bluetooth devices use short-range radio waves to transmit data. broadband.
Is an amount of data that can travel over a communications channel?Bandwidth is the capacity of a wired or wireless network communications link to transmit the maximum amount of data from one point to another over a computer network or internet connection in a given amount of time -- usually one second. Synonymous with capacity, bandwidth describes the data transfer rate.
Which of the following terms is the time it takes a signal to travel?Latency is a synonym for delay. In telecommunications, low latency is associated with a positive user experience (UX) while high latency is associated with poor UX. In computer networking, latency is an expression of how much time it takes for a data packet to travel from one designated point to another.
What is it called when two or more devices transfer data instructions and information?Computer communications describes a process in which two or more computers or devices transfer data, instructions, and information.
