Why very low frequency is having no use for data transfer in computer network?
Low frequency devices are losing popularity in computer networking because of their slow transfer rates. The higher the frequency of a device the faster it can transfer data.
Advantages and disadvantages of speakers?
Improve the sound of computer or other device. Take up a lot of room cost a lot and are easy to break
What are the advantages of wireless communications?
A: The advantage is that no wires are needed to communicate. Example printer to computer. Obviously there are some disadvantages the power output is very limited in range. Why because if not limited it may interfere with other hubs or worst stealing info with a receiver.
What frequency is 72.790 mhz?
The Hertz is a unit of frequency(Hz). 1 Hertz is equal 1 cycle per second. 2 Hertz is equal 2 cycles per second. ... mega means 10^6 mhz means megahertz what is 10^6 Hertz = 1000000 Hz 72.790 mhz is equal a 72.790 * 1000000 Hz. It is a high frequency. Currently the computer processors are measured in gigahertz(GHz) = 10^9 =1000000000.
What equipment uses a crystal oscillator in its operation?
Your quartz watch, your cell phone, all electronics that uses a computer inside. The quartz crystal forms the time base for the digital pulses. Crystal oscillators are also used in radio receivers and transmitters to provide accuracy in frequency selection. In a transmitter it provides the exitation frequency. In the receiver it provides the local oscillator in a superhetrodyne setup. Multifrequency devices (tunable and channelised radio) take the local oscillator and multiply and divide it, to provide a comparison frequency for a voltage controlled oscillator (VCO). The VCO is then controlled by a Phase Locked Loop (PLL) which holds the required frequency very accurately.

What is multiplexing in computer network?
multiplexer is a device that add two or more signal in a single signal in networking
What is a synchronizer?
Synchronous motors are those that run only at Synchronous speed ie.. constant speed.
What does multiplexing mean?
In electronics, telecommunications and computer networks, multiplexing (short muxing) is a term used to refer to a process where multiple analog message signals or digital data streams are combined into one signal over a shared medium. The aim is to share an expensive resource. For example, in electronics, multiplexing allows several analog signals to be processed by one analog-to-digital converter (ADC), and in telecommunications, several phone calls may be transferred using one wire. In communications, the multiplexed signal is transmitted over a communication channel, which may be a physical transmission medium. The multiplexing divides the capacity of the low-level communication channel into several higher-level logical channels, one for each message signal or data stream to be transferred. A reverse process, known as demultiplexing, can extract the original channels on the receiver side. Multiplexing technique is designed to reduce the number of electrical connections or leads in the display matrix. Whereas driving signals are applied not to each pixel (picture element) individually but to a group of rows and columns at a time. Besides reducing the number of individually independent interconnections, multiplexing also simplifies the drive electronics, reduces the cost and provides direct interface with the microprocessors. There are limitations in multiplexing due to complex electro-optical response of the liquid crystal cell. However, fairly reasonable level of multiplexing can be achieved by properly choosing the multiplexing scheme, liquid crystal mixture and cell designing.
What is synchronus capacitor?
A synchronous condenser (also known as a synchronous capacitor or synchronous compensator) is a DC-excited synchronous computer (large rotating generators) whose shaft is now not connected to any using equipment.
What is the meaning of memory 3gb 1066mhz DDR3 SDRAM?
They are RAM (memory) chips for use in a computer.
The device that combines the parallel input data into single serial output data is known as?
Multiplexer(Multiplexing).In telecommunications and computer networks,multiplexing(also known as muxing) is a method by which multiple analog message signals or digital data streams are combined into one signal over a shared medium.
What is the actual term for computer memory sdram?
The actual term for computer memory SDRAM is Synchronous Dynamic Random Access Memory. You can learn more about SDRAM online at the Wikipedia website.
Why very low frequency is having no use for data transfer in computer network?
Low frequency devices are losing popularity in computer networking because of their slow transfer rates. The higher the frequency of a device the faster it can transfer data.
Under computer advantages what's the meaning of speed?
When we speak of computer speed we are referring to the number of CPU cycles per second. The higher the frequency, the more operations we can perform in a given time frame. Supercomputers, however, are measured in terms of floating point operations per second.
What are the advantages of computer for the student?
The internet. Baaack in the day, they had libraries, where you had to spend hours researching in...books. Yes. WikiAnswers. This is one of the advantages of the computer.
