The Internet is a global system of interconnected computer networks, consisting of millions of private and public, academic, business, and government networks of local to global scope that are linked by copper wires, fiber-optic cables, wireless connections, and other technologies. The Internet appears to its users as a single worldwide network accessible to the general public. The protocol that makes it possible to use the millions of networks composing the Internet as if they were one network is a special type of packet switching known as IP or The Internet Protocol.
A computer that connects to the Internet can access information from a vast number of servers and other computers. An Internet connection also allows the computer to send information through the network; that information may be saved and ultimately accessed by a variety of servers and other computers. Much of the information widely accessible through use of the Internet consists of the interlinked hypertext documents and other resources of the World Wide Web (WWW). Web users typically send and receive information using a web browser. Other software for interacting with computer networks includes specialized programs for electronic mail, online chat, file transfer and file sharing.
Information is moved around the Internet by packet switching using the standardized Internet Protocol Suite (TCP/IP)which defines how packets are moving in any platform especially the transport layer. The Internet Protocol Suite consists of several layers of protocols. The lowest layer (the link layer) deals with protocols that transmit data over specific technologies, such as Ethernet or Wi-Fi. The highest layer (the application layer) supports specific applications, such as e-mail and file transfer. In between are the Internet layer, which provides for transmitting packets over any conceivable technology, and the transport layer, which provides for various services such as reliable delivery of packets or real-time streaming of packets.
Search engine optimization
(SEO) is the process of improving the volume and quality of traffic to a web site
from search engines
via "natural" search results
. Usually, the earlier a site is presented in the search results, or the higher it "ranks," the more searchers will visit that site. SEO can also target different kinds of search, including image search
, local search
, and industry-specific vertical search
engines. As a marketing
strategy for increasing a site's relevancy, SEO considers how search algorithms
work and what people search for. SEO efforts may involve a site's coding, presentation, and structure, as well as fixing problems that could prevent search engine indexing programs from fully spidering
a site. Other, more noticeable efforts may include adding unique content
to a site, and making sure that the content is easily indexed by search engines and also appeals to human visitors. The acronym "SEO" can also refer to "search engine optimizers," a term adopted by an industry of consultants
who carry out optimization projects on behalf of clients, and by employees who perform SEO services in-house.
Webcams are small cameras, (usually, though not always, video cameras) whose images can be accessed using the World Wide Web, instant messaging, or a PC video conferencing application. The term webcam is also used to describe the low-resolution digital video cameras designed for such purposes, but which can also be used to record in a non-real-time fashion.
Marc Andreessen (born July 9, 1971, in Cedar Falls, Iowa and raised in New Lisbon, Wisconsin, United States) is a software engineer and entrepreneur best known as co-author of Mosaic, the first widely-used web browser, and co-founder of Netscape Communications Corporation. He was the chair of Opsware, a software company he founded originally as Loudcloud, when it was acquired by Hewlett-Packard. Netscape's success attracted the attention of Microsoft, which recognized the web's potential and wanted to put itself at the forefront of the rising Internet revolution. Microsoft licensed the Mosaic source code from Spyglass, Inc., an offshoot of the University of Illinois, and turned it into Internet Explorer. The resulting battle between the two companies became known as the Browser Wars. Andreessen is an investor in social news website Digg and serves on the board of Open Media Network. He is also a cofounder of Ning, a company which provides a platform for social-networking websites.
