Basically
Each device (PDCU Portable Data Capture Unit) like they type used in supermarkets and warehouses collects the data from either a manual or automated capture. The information is the broken in to code (normally binary) and transmitted using a radio frequency specific to that device to a receiver/modem - here it is identified and the data collected and stored. In most buildings a wire loop is placed around the main work area. This acts as an Ariel making the transmission and recipt of data easier. A laptop to laptop connection in a house works very much the same only here each PC will have to be told to recognise another in its wireless catchment area. The data is transmitted by one laptop to the wirless modem, This sends it to the airwaves the other machine will then capture this information by its moden (wireless card)

Why must sound and video input to a PC be converted from analog to digital?
Because in order to preserve the original sound, a digital sampling rate must be twice the frequency of the analog signalAnalog data is smooth and continuous, where as digital data, such as the binary data used in computers, has distinct gradations. The process of producing digital data by measuring data at a series of representative points is called sampling.
Is data stored in computer is in digital form?
Yes, it is.
What is an electronic device that processes data?
There are different types of processing devices. Processing devices with computers are devices that transform computer data into a usable format for the user. The devices can perform many different functions such as store data, analyze and sort data, record and display data, and calculate and summarize data. The device processes the input into useful output. The central processing unit in a computer processes and stores the data inputted into the computer. It works with the motherboard and the random access memory. Other types include microprocessors and multi-core processors.
What is data cable?
Just as electric cable transmits electric line power from the transmission center to receiving station so the data cable in digital communication transmits the encoded binary digits from a digital transmission system to a digital receiving system.
What is digital transmission of analog data?
it means that you digitize analog data for transmission . Like 2 computer that chatting .
What lets you transfer digital data between your computer and devices such as digital cameras?
connectivity port.
What are the Source Data Automation devices?
Source data automation devices are devices that help collect data in its original digital form. Instead of translating or transcribing data, this allows for the direct collection of information.
Similarities between digital and analog devices?
Digital and analog devices share some similarities, despite their fundamental differences. Here are some similarities between digital and analog devices: Input/Output (I/O) Capability: Both digital and analog devices are capable of receiving input data and producing output data. Input can be in the form of various signals or data, and output can be in the form of displays, sounds, or other forms of feedback. User Interaction: Both digital and analog devices can be interacted with by users to perform tasks or operations. For example, both digital and analog devices can have buttons, switches, knobs, or touchscreens that allow users to interact with them and control their functions. Processing Capabilities: Both digital and analog devices are capable of processing data or signals in some form. Digital devices process data in discrete binary values (0s and 1s), while analog devices process continuous signals with varying voltage or current levels. Signal Conditioning: Both digital and analog devices may require signal conditioning to ensure accurate input and output. For example, analog devices may require amplifiers or filters to condition signals, while digital devices may require analog-to-digital converters (ADCs) or digital-to-analog converters (DACs) to convert between analog and digital signals. Applications: Both digital and analog devices are used in a wide range of applications, such as communication systems, audio and video processing, control systems, measurement and instrumentation, and more. They can both be used in various fields, including electronics, telecommunications, medical devices, automotive systems, and industrial automation, among others. Functionalities: Both digital and analog devices can provide various functionalities, such as data storage, data processing, data transmission, and control functions. While the implementation may differ due to the nature of digital or analog signals, the overall functionalities can be similar in some cases. Integration: Both digital and analog devices can be integrated into larger systems or networks to perform complex tasks or operations. They can be combined to create hybrid systems that leverage the advantages of both digital and analog technologies. Despite these similarities, it's important to note that digital and analog devices differ significantly in how they represent and process data or signals. Digital devices use discrete values and binary logic, while analog devices use continuous signals and analog circuitry. Understanding these differences is crucial in designing and working with digital and analog devices effectively.
What are the advantages of using NDMP?
Network Data Management Protocol or NDMP is used to transport data between NAS devices and backup devices. It is a faster transfer protocol because the data does not transport through the backup server.
Does a digital device work with continious data?
Depending on what sort of digital device you are asking for, it can work with continuous data. Majority of digital devices work with continuous data. However, it is hard to give answer without knowing the exact device.
Which statements apply to packet switching?
It transmits each packet in a multipacket message independently It supports interoperability between digital devices with different data rates
How do you technology fueling the Digital revolution?
digital electronics use electronic circuits to represent data. in the 1940's and 1050's, engineers began to develop digital electronic devices and refine the elctronic components used to build them.
What is the function of the data link layer?
exchanging of data between interconnected devices
What is a data bus?
A data bus is a group of connections running throughout a digital system (e.g. computer) that attaches to all the various units in that digital system that process or generate data (e.g. ALU, memory, register set, I/O devices). Only one unit that is connected to the data bus can be enabled at a time to drive it with a data value. Most digital systems have only a single data bus, but some (e.g. digital signal processing computers) may have more, allowing several different data values to be passed between units simultaneously instead of just one at a time.
What lets you transfer digital data to computer and devices such as digital cameras?
there should be a usb for it. plug the usb in to the computer and the other side of the cable should plug into the device
Which material is used in display devices such as digital watches?
These days, liquid crystal displays are used to display data in digital watches. They are also use in pocket calculators and portable computers. LCD displays utilize two sheets of polarizing material with a liquid crystal solution between them. An electric current passed through the liquid causes the crystals to align so that light cannot pass through them.
What is the difference between a modem and a codec?
* Codec is for coding analog data into digital form and decoding it back. The digital data coded by Codec are samples of analog waves. * Modem is for modulating digital data into analog form and demodulating it back. The analog symbols carry digital data.
