refers to any network of interconnected networks.
internet (with small I)
refers to the global system of interconnected networks that we use in our day-to-day lives.
Internet (with capital I)
can be any interconnected-network of computers or similar things between any organization(s) or group of people which may not be known or accessible to the public.
internet (with small I)
the kind of inter-network or internet in short which we are using now, i.e. “www”(World wide web).
the largest internet we have in this world which comprises of trillions of computers being connected to each other. Because of its size, it is very much public.
Internet (with capital I)
a massive network of networks, a networking infrastructure that uses TCP/IP to transmit data via various types of media.
Internet (with capital I)
sometimes called simply “the Net”
Internet (with capital I)
the space of electronic movement of ideas and information.
cyberspace
Rather than moving through geographical space, it moves your ideas and information through cyberspace
Internet (with capital I)
a network of networks in which users at any one computer can, if they have permission, get information from any other computer (and sometimes talk directly to users at other computers)
computer networks
a worldwide system of computer networks
Internet (with capital I)
TCP/IP stands for:
Transmission Control Protocol/Internet Protocol
a suite of communication protocols used to interconnect network devices on the internet.
also used as a communications protocol in a private computer network (an intranet or extranet).
TCP/IP (Transmission Control Protocol/Internet Protocol)
The origins of the internet are rooted in the USA of the ______.
1950s
Computers in the 1950s, back then filled up entire rooms scientists and researchers used it for years to communicate during the ________. At this time, computers were large, expensive machines exclusively used by military scientists and university staff.
Cold War
the first practical schematics for the internet would not arrive until what year?
Early 1960s (1962)
Who popularized the idea of an “Intergalactic Network” of computers.
MIT’s Joseph Carl Robnett Licklider
a method for effectively transmitting electronic data that would later become one of the major building blocks of the internet.
packet switching
the transfer of small pieces of data across various networks.
a method of splitting and sending data
packet switching
A computer file is effectively broken up into thousands of small segments called what?
packets
each packets are typically around _________. Distributed across a network, and then reordered back into a single file at their destination.
1500 bytes
This method is very reliable and allows data to be sent securely, even over damaged networks; it also uses bandwidth very efficiently and doesn’t need a single dedicated link, like a telephone call does.
packet switching
In this year, the first version of the internet was created and set up as a network
1969
the first version of the internet was created and set up as a network called ARPANET, ARPANET stands for:
Advanced Research Projects Agency Network
. A student programmer named ________ sent the first message over ARPANET
