Physics or Science , is interested in extending the knowledge base of various aspects of the natural world and phenomena by systematic study, effective experimentation and aut…hentic analysis; and probe why and how do things happen, but may not necessarily be interested in practical applications of these findings. Whereas, Technology , is concerned with innovative applications of scientific intellect and inventions; Not much interested to know why and how? Instead want to know what happens and in what way these can be developed into a useful system to work better. Further, there is some thing to add here! Engineering is involved intelligently in employing and applying the technological development more economically for the benefits and comforts of the society by producing promising physical products. These are the extracts of Popular talk on SCIENCE, TECHNOLOGY AND ENGINEERING: PEOPLEâS POPULAR PERCEPTION AND PARADIGM by Dr. PK Roy . .
I wanna say that one Two Three Person use is a technics and Multiple using anythig is a Technology That is.
In Baseband, data is sent as digital signals through the media as a single channel that uses the entire bandwidth of the media. Baseband communication is bi-directional, which… means that the same channel can be used to send and receive signals. In Baseband no frequency-division multiplexing is not possible. (Multiplexing (short muxing) is a process where multiple analog message signals or digital data streams are combined into one signal over a shared medium.) Broadband sends information in the form of an analog signal. Each transmission is assigned to a portion of the bandwidth, hence multiple transmissions are possible at the same time. Broadband communication is unidirectional, so in order to send and receive, two pathways are needed. This can be accomplished either by assigning a frequency for sending and assigning a frequency for receiving along the same cable or by using two cables, one for sending and one for receiving. In broadband frequency-division multiplexing is possible
Iam pretty sure that baseband coax was 50 ohm and was used for networking computer, were broadband coax is 75 ohm and used in the cable tv industry. A baseband signal is the …original signal before it is modulated onto a carrier, mulitplexed or mixed. A broadband signal contains many channels which have been modulated or multiplexed onto a common carrier. The significant difference is the bandwidth of each. The impedance of the cable which carries either of them is totally irrelevant to the definition.
can you just tell me the meaning of the question above?
Baseband is a type of transmission that uses current to send a signal over the wire as digital wave. Broadband uses analog signal to transmit thru different frequencies, w…hich increases the amount of data carried at one time.
BASEBAND is when a signal is in it's native format. For example, voice has a baseband of 20-20000Hz. BROADBAND is typically referring to a case where a signal is modulated out… of its baseband into another "carrier signal." Typically, that broadband medium is shared by many different baseband signals. For example, FM Radio signals have a baseband of human voice, and that baseband is modulated on to a carrier in the 88-108 MHz range. Dozens of baseband human voices can be put into the broadband range that is FM radio.
The difference between baseband coaxial and broadband coaxial cable is baseband coaxial technology uses digital signaling in which the cable carries only one type …of digital signal. Where as the broadband coaxial technology typically transmits analog signals and is capable of transmitting multiple frequencies of data simultaneously.
Baseband Signalling: 1)Uses digital signalling 2)No frequency-division multiplexing 3) Bi-directional transmission 4)Signal travels over short distanc…es Broadband Signalling: 1)Uses analog signalling 2)Unidirectional transmission 3)Frequency-division multiplexing is possible 4)Signal can travel over long distances before being attenuated
Baseband coaxial cables are 50 ohm cables used for 'digital transmission'. For 1Km cables the bandwidth is 1-2 Gbps. Longer cables can be used with low data rates or per…iodic amplifiers. Broadband coaxial cable are 75 ohm cables used for analog transmission. They use standard cable television technology. To transmit digital signals on an analog network, each interface must have converters i.e analog to digital for outgoing bit stream n vice versa Another difference b/w baseband and broadband is that broadband systems have developed dual cables. Since broadband is used for large area, it requires amplifiers which are unidirectional. In dual band systems two identical cables run together, one used for outgoing data, one for incoming data. Different bandwidths are given for inbound and outbound cables. Eg: for 300MHz , 5-30MHz for inbound and 40-300MHz for outbound.
Information technology is a specific type of technology involvingthe processing, storage, and exchange of information. Technology is a very broad field involving the knowledge… of makingany kind of tool, the making of things needed to make and use thosetools, and many other related things. Even the making and using ofearly stone tools is a technology. Even our early prehumanancestors had technologies and no modern human (even many thousandsof years ago) has lived without having many technologies that theyused every single day. The word 'technology' can apply to anything - from a ball-point pen to a Boeing 777. Information technology usually just refers to computer-related objects etc.
baseband its the software base broadband its the internet connection name speed
technology is when someone create something an language is what u talk
Baseband Channel uses a low pass channel (a channel whose frquency range is 0 to infinity) whereas Broadband connection uses band pass channel (whose frequency range is betwee…n f1 and f2).So broadband connections can be used for multiple signals with different frequency ranges. Navdeep S Sony
The difference between technology and technological change is that one is a process and one is a change in that process. Technology takes something that is input and makes… it output. A technological change involves taking that technology and tinkering with it to change the output levels.
I am not sure what you mean but I assume your question is directed on why there are so many broadband technologies such as ADSL 3G 4G T1 T3 etc etc. Every unique broadband te…chnology has advantages and disadvantages and it is up to the end user to determine which technology suits him better or would work. For example - ADSL connections have very fast download speeds through simple twisted pair. However it is limited in town that already have the infrastructure to support it and it is also much cheaper than DSL (synchronous DSL where upload speeds match download speeds). - Satellite connections have a major disadvantages in ping replies thus they are not suited for browsing or online games. However they are very fast when trasmitting or receiving a big file. The other advantage of satellite connections is that it can be used virtually anywhere in the world provided you have a receiver. - 3G, 4G the main advantage of these technologies is that they are quite capable for browsing and with 4G even download speeds are quite fast. Not as fast as ADSL but they can be used wirelessly anywhere there is a cellular network that supports it. However such data plans can be expensive and is not the best option for stationary office work. Also once you leave the network support you have no connection. - Direct line - Dedicated and you share no bandwidth with nobody else, ultra fast and ultra reliable but extremely expensive. These technologies are not number 1 preference anymore due to ADSL becoming faster and more stable while it is also much cheaper to own 3 or 4 ADSL connections rather than one direct line subscription. Then there are terminal technologies that are wires and wireless. Wires include, cable, fiber optic and twisted pair, CAT 6, CAT 5. Twisted pair is still the most widely used wiring technology worldwide because the infrastructure is there from the 1900's Cable provides more bandwidth and less interference that twisted pair but is bulky and expensive. Fiber Optic cables. They are expensive but they are extremely (the fastest available) fast and the cost of repairs is actually cheaper than cable or twisted pair because you can determine exactly were the fault is and exchanging the faulty part is very easy. CAT 5 and CAT 6 are network cables, the one's that will connect end users or modems. CAT 5 is the norm but CAT 6 can handle more data and the newer VDSL version so it is slowly replacing CAT 5. Then there various wireless technologies like A band, B band, G band, N band. Suffice to say that they are the same but upgraded with N band being the fastest and with the longer range (causes more interference though)
