1. Server (computing), a server application,
operating system, computer, or appliance
·Application server a server dedicated to running certain software applications Example PMS2k3
holds all of our applications for Perry Middle School: Classworks; Typing software
·Communications server , carrier-grade computing platform for communications networks Example
Email Server Database server , stores data for retrieval Example in Houston County:
AS400/SmartWeb
·Fax server provides fax services for clients
·File server provides file services
·Home server a server for the home
·Print server provides printer services
·Web server , a server that HTTP clients connect to in order to send commands and receive
responses along with data contents
·Web Feed Server , a server that distributes, manages, and tracks internal and external RSS feeds
an enterprise
·Client-server , a software architecture that separates "server" functions from "client" functions

2. Protocol is a convention or standard
that controls or enables the connection
Internet protocol (IP)- Server assigns an IP
address to each computer when it comes
online. CANNOT connect to the Internet or
LAN without an IP address.

3. A computer network is a group of interconnected computers and
network printers.
Router
Switch

4. WAN- Wide Area Network
is a computer network that covers a broad area (i.e., any network
whose communications links cross metropolitan, regional, or national
boundaries). Connects all LAN servers and all networked computers.
Example: Houston County School System
LAN- Local Area Network
is a computer network covering a small geographic area, like a home,
office, or group of buildings e.g. a school. Computers are connected to
a server. Faster file acquisition due to small area.
Example: Perry Middle School

5. ·The largest computer network in the world (a
network of networks)
·Information exchange is seamless using open,
non-proprietary standards and protocols,
within interconnected networks
·A true democratic communications forum
producing a democratization of information
·Spirit of information sharing and open access
underlies the Internet.

6. ·Packets of information flow between machines governed by
common rules (protocols):
·Internet is a packet-switching network
·Messages are decomposed into packets, containing part of the message, plus
information on the sending and receiving machines and how the packet relates
to the other packets
·Packets travel independently and possibly on different routes through the
Internet
·Packets are reassembled into the message at the receiving machine.

7. HTTP- Hypertext Transfer Protocol
is a URI scheme or network protocol for the transfer of information on the
Internet. Its use for retrieving inter-linked text documents led to the
establishment of the World Wide Web.
HTTPS - Hypertext Transfer Protocol over Secure Socket Layer
is a URI scheme used to indicate a secure HTTP connection.
FTP- File Transfer Protocol
is a URI scheme or network protocol used to transfer data from one
computer to another through a network such as the Internet.

8. URI -Uniform Resource Identifier
is the top level of the Uniform Resource Identifier. All URIs and absolute URI
references are formed with a scheme name, followed by a colon character (":").
Example: http:
URL - Uniform Resource Locator
is an URI which also specifies where the identified resource is available and the
protocol for retrieving it. It is a means of accessing a network location.
