INTERNET
BUZZ WORDS AND PHRASES
INTERNET
-
a huge network of server
computers covering the entire globe connected together like a giant spider web
of communications links
SERVER COMPUTER – a
computer on the internet that is dedicated to providing a service to client
computers - A few examples of services are: news, financial information,
product sales, email, graphics, and search engines that provide information access
CLIENT
COMPUTER - the computer you are using is the client computer.
INTERNET
SERVICE PROVIDER – there are companies that provide the
communications connection between client computers and internet server
computers, and they are identified as Internet service providers (ISPs)
WORLD
WIDE WEB (www) –a network of server computers covering the
entire globe having an address starting with www or http:// - actually the World
Wide Web is a subnet of the Internet that piggy backs on the
Internet for its communications. There are many other sub networks that that
use the Internet like the private Intranets of large corporations, and the File
Transfer Protocol Net used by research
universities that uses an address starting with ftp://
WEB
SITE ADDRESS - starts with www or http:// and then a
domain name and then a suffix - examples
www.shellpoint.net or www.google.com or www.hotmail.com or www.nga.gov (it is estimated that there are
approximately 100,000,000 web addresses on the World Wide Web subnet of the Internet)
HTTP-
http:// stands for hypertext transmission protocol which is the language that
the world wide web (www) sub network uses to communicate between clients and
servers and vice versa. In the digital world protocol and language are similar
concepts. Computers/internet use protocols – humans use languages, and like
languages there are many different protocols.
EMAIL
ADDRESS – the address of your personal or business mail box
in on a server on the internet examples richnelson@hotmail.com
or richrnelson@gmail.com – an email
box resides on a web site and each email address is unique.
NOTE: notice above the difference between a web site
address and an email address
CLIENT/SERVER

the server computer- the client computer is lower in the hierarchy than the
server computer
DOWNLOADING

the client computer
UPLOADING

the client computer to the server computer
INTERNET PACKETS – All information
transmitted on the internet is put in standard size packets and sent as
individual packets across the internet’s various communication paths that are
like a giant spider web.
An analogy would be if you wrote a multi-page letter and put it in the US Mail with
each page of the letter in a separate envelop and numbered the envelops ( like 1 of 5, 2 of 5, etc).
And the person receiving the letter would count the envelops to make sure that
all 5 got there and if not send a message back to the sender advising that
envelop #3 didn’t make it, and for the sender to resent envelop 3. And the
sender would resend envelop #3
I suggest you google TCP/IP to get more in-depth info if you like.
INTERNET PACKET PROTOCOR – TCP/IP –
transmission control protocol/Internet protocol – this is the worldwide
standard specifying how the packets are formed and transmitted across the
internet spider web
DIGITAL TECHNOLOGY – In the
computer/internet world the transmission of information is done using zeros and
ones (0 and1). This called a binary system of communicating. (Binary meaning
two) So all the symbols we humans use
are translated into a system of zeros and ones. All the letters of our alphabet
and our number system is translated into a system of 8 zeros and ones called
the American Standard Code for Information Interchange or ASCII.
Digital pictures and photographs on a computer or the internet are also
translated into a system of zeros and ones by dividing the picture unto a bunch
of little squares called pixels (picture elements). Each is a unique combination of zeros and
ones representing a specific color and shade of that color. Each pixel
frequently has as many as 24 or more zeros and ones to represent a unique color
pixel
