ब्रॉडबैंड क्या है
What is Broadband Internet Connection mean and speed in Hindi: Broadband Internet Connection हाई स्पीड internet connection को बोलते है जिसकी speed किसी भी traditional dial-up इंटरनेट कनेक्शन की speed से ज्यादा होती है | In telecommunications, broadband term का meaning होता है wide bandwidth data transmission, जिसमे की एक साथ multiple signals and traffic को ले जाने की capacity होती है | इसके लिए communication medium coaxial cable, optical fibre, radio or twisted pair कोई भी use किया जा सकता है |

Broadband ज्यादातर घर पर या छोटे
बिज़नेस मे use किया जाता है – ब्रॉडबैंड भी कई प्रकार का हो सकता है जैसे –
1. ‘Fixed Broadband’ Connection at होम-
जिसमे की आपकी डिवाइस को केबल से modem/router
से कनेक्ट
किया जाता है
2. Radio Waves to connect devices with a
wireless connection.
3.
Mobile Broadband Connection – इसमे USB मॉडेम डिवाइस
को use किया जाता है जो की wireless connection होता है एवं mobile
phone towers से कनेक्ट
करके fast इंटरनेट स्पीड प्रोवाइड करता है |
BASEBAND
बेसबैंड - इस ट्रांसमिशन में सम्पूर्ण मीडिया बैंडविड्थ को एक सिंगल
चैनल में प्रयोग किया जाता है बेसबैंड सामन्यता डिजिटल सिग्नल के लिए प्रयोग किया
जाता है इसे एनालॉग सिग्नल के लिए भी प्रयोग कर सकते है अधिकतर lan बेसबैंड सिग्नलिंग को प्रयोग करते
है|
What is the baud rate?
baud, baud rate A baud is the number of signalling
elements per second sent by a communications device such as a modem, In theory,
a modem with a high baud rate means fast transmission. The baud rate is
therefore equal to the bit rate only if each signal element represents one
bit of information.
Unfortunately, in much of today's literature, the terms "baud"
and "bits per second" are used synonymously. This is correct in cases
where pure two-state signalling is used but is incorrect in general. For this
reason, the term "baud" is gradually being replaced by "bits per
second," since the latter is independent of the coding method and truly
represents the information rate.
When you use a modem to send information from one computer to another over the phone lines, the information moves at a certain
speed. This speed is measured in bits per second, a bit being one
electronic unit of information. This bits-per-second rate is also commonly
called the baud
rate (pronounced
"bod"). It's a measure of how fast your modem can send and receive
information. Modems most typically send at 1200, 2400, or 9600 baud.
Now, I do have to warn you that even though the masses (that's us) often
use the term "baud" to mean the same thing as "bits per
second," this is technically incorrect, and someday someone will surely
scold you. One baud is actually one "modulation change" or one
"signal event" per second on a communications channel. It's only at
300 baud that one signal event equals one bit per second. A modem operating at
1200bits per second needs only one signal event to send 2 bits, so if you want
to be pernickety you should call it a 600 baud modem. See bps for a
discussion of common communications speeds and how they translate into speed
ratings you can relate to.
The term "baud" is named after the inventor of the Baudot
telegraph code, J.M.E. Baudot.
