What are the maximum upstream and downstream transfer rate for DSL and cable connections?
Cable systems provide rates of approximately 500 Kbps downstream and 128 Kbps upstream. Theoretically they can provide a bandwidth of 30 Mbps. A DSL system can provide speeds of up to 7.1 Mbps, but most providers offer a maximum of 1.5 Mbps upstream and downstream.
How did teenagers communicate in the 1910s?
they talked. i know it may be shocking, but yes it is true. they actually talked. besides, a phone was already around in the 1910s they just didn't use it that much as it was expensive
Why fiber optic communication offers largest bandwidth?
- Copper wire twisted pair and coax lines act like a lumped LC low pass filter, strongly limiting bandwidth.
- Microwave waveguides and transmission are limited by microwave frequency used.
- Fiber optics uses IR or visible spectrum allowing wider modulation bandwidth than microwave can. Also different beams can follow different paths through the fiber without interfering, allowing a form of multiplexing not usable with other media.
Is a BT telephone socket the same as a NTL telephone socket?
Physically they are identical, all standard UK house phones will plug into either socket. The key difference in how some of the exchange end services are implemented. For example, house phone SMS services may use different protocol and might CLi. It you are using the line as simple phone you should have no trouble with any combination of phone/socket.
What is the greatest achievement of India in the last decade?
The constitution of India is itelf a greatest achivement after the independence... coz, India having lot of many category peoles r tr... by considering all the peoples... Dr, Ambedkar Framed well stuctured rules,policies to live in the scocity... By seeing other sectors we can achive those it may be getting nobel,oscor, those r not the achievemnts.... but now also it is valid.... this month technology become a next month joke.... but it is not like that.... we once again thank to Dr.B.R.ambedkar..... thank u....!!!
What are telecommunication processors?
Telecommunications processors. Support data transmission and reception between terminals and computers. They include modems and switches. A modem provides an interface between a computer (or network) and the phone line, cable line (or cellular connection).

How does public speaking as a communication work?
Communication requires a sender and a receiver. In public speaking, there is not a continual switching of the sender and the receiver. The speaker is the sender in a public speaking situation.
An AT&T 3G sim card will work in a new iPhone.
yessss you can :) but the box for the iPhone comes with a little tool to help you open the little compartment for the sim card.... its hidden right under that part where the phone is displayed, under that flap thing....... yeah... WELL its silver and has a small tip! not hard to miss! :) okay bye!
What is the difference between microwave communication and Optical communication?
Only the frequency of the communications carrier. Microwaves are electromagnetic radiation in the frequency range of 3 gigahertz to 300 gigahertz. Electromagnetic radiation above those frequencies are considered "optical" even though you can see only a small percentage of them with your eyes.
What arer the phases of a project development cycle give the salient tasks under each phases?
Software development is achieved through collection activities that lead to the building of a software product. Software development is traditionally divided into various phases, which we describe briefly in the following sections.
Requirement Phase:-
The development process usually begins when the client approaches a development of organization in regard with a piece of software, with the opinion of client to the profitability of an enterprise. The task of developer is to determine exactly what the client needs and find out their cost and deadline of software. Software development is an expensive process.
Specification Phases:-
The requirement must be understood by the developers, when client agrees; the specification document is drawn by the specification team. In the specification document, the functionality of the software is described. The specification document of the software is part of contract, where as contract software development can lead to a lawsuit, the document should be written as evidence.Planning Phase:-The plan describes the software process in detail, and also it includes structure of development organization, project responsibilities, technique, managerial objective etc to be used. Detail schedule, budgets and resource allocation are also made. In planning duration and cost estimation are important.Design phases:-The design phase is to determine how the software works. With specification document, internal structure of the software is determines by the design team. Algorithm, Architecture design, data design, data structure are made in this phase. The major output of design phase is architectural design and detailed design.Implementation Phase:-The various modules of the design are coded in this phase. The major documentation is associated with implementation is the source code itself, but the programmer should provide additional documentation to assist in maintenance. All test cases against the code was tested for the actual and expected outputTesting phase:-In this phase modules combine and determine whether the software works correctly or not. All modules are integrated in a specific order for the critical influence on the quality of software. The purpose of integration testing is to check that modules combine correctly, so that it achieved task and satisfies the specificationMaintenance Phase:-Maintaining and enhancing software to cope with newly discovered problems or new requirements can take far more effort than the initial development of the software. Not only may it be necessary to add code that does not fit the original design but just determining how software works at some point after it is completed may require significant effort .The software has been hand over to client and changes as a part of maintenance.packet switching is use today
