Difference between Ethernet and internet?
Ethernet is a set of standards for physically connecting computers in a local area network. In terms of OSI network layers, Ethernet provides only the physical layer and the data link layer. The Internet is a global, physical network of millions of computers that communicate by sending and receiving packets of data. The Internet supports many different communication protocols for different applications: e-mail, file transfer, domain resolution, remote terminals and hypertext. In terms of network layers, Internet standards define the network layer and transport layer. Internet services can be carried on Ethernet connections for short distances but other data link technologies are required to construct wide-area networks.
What are the latest developments in web technology?
The World Wide Web (known as "WWW', "Web" or "W3") is the universe of network-accessible information, the embodiment of human knowledge. The Web has a body of software, and a set of protocols and conventions. Through the use hypertext and multimedia techniques, the web is easy for anyone to roam, browse, and contribute to. An early talk about the Web gives some more background on how the Web was originally conceived. The recent growth of the Internet and the World Wide Web makes it appear that the world is witnessing the arrival of a completely new technology. In fact, the Web--now considered to be a major driver of the way society accesses and views information--is the result of numerous projects in computer networking, mostly funded by the federal government, carried out over the last 40 years. The projects produced communications protocols that define the format of network messages, prototype networks, and application programs such as browsers. This research capitalized on the ubiquity of the nation's telephone network, which provided the underlying physical infrastructure upon which the Internet was built.

How does information travel through wires Internet cabel television ext.?
The Internet is based on packet-switched protocols. Information is carried in packets, which can be imagined as small parcels being passed from computer to computer. Large chunks of data are usually broken up into several smaller packets before being sent through the network. The delivery mechanism, or protocol, that is used to encode the packet ensures safe transit, and provides a way of reconstructing the data when it reaches its destination. The protocols used on the Internet are referred to as TCP/IP, standing for Transmission Control Protocol / Internet Protocol. As a switched network, the physical connections between computers do not matter as far as Internet traffic is concerned - the protocols ensure that guaranteed information delivery is more important than speed or use of a particular route. This means that a sequence of packets might arrive out of order, with some travelling through the net by a faster, shorter route than others. TCP/IP provides the means for your software to piece together those packets into meaningful data. The ability to take different routes through the network is a fundamental part of the original design of TCP/IP, as it allows the Internet to route around damaged areas of the network.
Who invented the first backpack?
Probably the stone age woman - she carried her baby in a early version of backpack.
Which of the following allows the transmission of telephone calls over computer networks?
Telephone conversations carried over the Internet or local networks is commonly transmitted through a protocol known as Voice over Internet Protocol, often abbreviated as VOIP or VoIP.
All VOIP calls are carried over the internet?
The call being made or received with VoIP is carried over the Internet. If you call a phone that is using PSTN (Public Switched Telephone Network) then they are not using the Internet for the voice transmissions. All calls made from VoIP though are indeed Internet.
Is Dish Networks internet satellite based?
Yes. Dish Networks offers internet service through a company called HughesNet. The transmit and receive devices are located outside in the form of a dish, and the signals are carried to an Indoor Receive Unit and Indoor Transfer Unit which carry the signal to your computer.

Why did they name mobile phone?
Probably because it is a telephone that can be carried anywhere - therefore, mobile.
Which voltage is carried by internet?
The internet does not carry a voltage. Indeed some of it runs over optical infrastructure.
A modern device that often has its signals carried through wires or glass optical fiber is a what?
telephone
