ISPs (Internet Service Providers) - Internet transmission or the delivery of traffic from
source to destination computers.
Hosts - Devices that are connected to the internet are called hosts.
IANA (Internet Assigned Numbers Authority) - controls and documents who owns
what IP addresses, since every single connected device outside of private networks
needs a unique address. The IANA prevents address duplication and ensures that
devices can access the World Wide Web.
IETF (Internet Engineering Task Force) - An organization that sets standards for how
systems communicate over the Internet (for example, how protocols operate and
interact).
Cloud - An image that indicates that the user does not need to know what goes on

, Rack Servers - A server that fits in a standard equipment rack. Most servers are
stored in equipment racks that are 48 cm (19 inches) wide and a standard height unit, or
U, is 1.75 inches tall. Each rack can hold several rack servers positioned one on top of
another.
U Formula:
U rack x U height = inches available space
22 U rack x 1.75 = 38.5 inches of usable space
Networked Applications - Those applications that require a network to communicate
with one another in order to function.
Your browser, which is your client program, sends a request message to the webserver.
This is an HTTP request message because HTTP (Hypertext Transfer Protocol) is the
standard for browser-webserver interactions. This request message asks for a file to be
delivered. The webserver server program on the webserver locates the file and sends it
back in an HTTP response message containing the requested file (or an error message
to say why it could not be delivered).
Client Program - Program that receives service from a server program on a server
host.
Request Message - In request-response cycles, a message a client programs sends
to request service from a server application program.
HTTP Request Message - In HTTP, a message in which a client requests a file or

HTTP (Hypertext Transfer Protocol) - The protocol that governs interactions between
