LADSE is a special education cooperative that Jonathan Adamczewski provided a tour of their network for. The network begins at the control room where the original phone lines entered the building and now serves as the entry point for phone and internet connections. From there, the connections run through a series of switches and Ethernet cables to hardwire the building and connect all the computers, printers, and phone systems. The servers in the server cabinet store all shared applications and storage. Wireless access points provide internet coverage throughout the building to ensure no dead spots. Even small networks like those in off-site centers consist of basic components like wireless routers, switches, and hardwired connections to make everything work together optimally.

This is a notes about basic introduction of computer networks. It contain details about the definition of computer network, ARPANET, goals of computer network, application of computer network and details about networking hardware & software components.
A computer network is a interconnection of two or more computers that are able to exchange information’s. Two computers are said to be inter connected if they are capable of
exchanging information.
• Network Goals/Advantages of Networking
This is Data Communication Lecture Assignment. Here discussed about many topics above the subject. I am really learned more from Data Communication subject. Specially thanks to Dear Respectable Sir Pranab Bandhu Nath

ntroduction
en you're surfing the Web, accessing software on your school's server, sending e-mail,
ecting your roommate use his or her computer to access the files on your computer,
:rr computer is part of a network. A computer network (which we simply refer to as a
~·ork) is two or more computers connected so that they can communicate with each
r and share information, software, peripheral devices, and/ or processing power.
y networks have dozens, hundreds , or even thousands of computers.
SIC PRINCIPLES OF NETWORKS
=;works come in all sizes, from two computers connected to share a printer, to the
--m et, which is the largest network on the planet,joining millions of computers of all
all over the world. In between are business networks, which vary in size from a
zen or fewer computers to many thousands.
- ome basic principles apply to all networks, large or small.
I . Each computer on a network must have a network interface (either as an
expansion card or integrated into the motherboard, or even through software
for a modem) that provides the entrance or doorway in that computer for
information traffic to and from other computers.
2 . A network usually has at least one connecting device (like a hub, switch,
or home/broadband router) that ties the computers on the network together
and acts as a switchboard for passing information.
3 . There must be communications media like cables or radio waves connecting .
A computer network is a digital telecommunications network that allows network nodes to share resources. In computer networks, computer devices exchange data with each other using connections (data links) between nodes. These data links are established via network cables such as wire or fiber optics , or wireless media such as Wi-Fi .
Network computing devices that launch, route , and terminate data are called network nodes. [1] Nodes are often identified by network addresses and can include network hosts such as personal computers , phones , and servers , as well as network hardware such as routers and switches. Two such devices can be said to be interconnected when one can exchange information with the other, whether they are directly connected to each other or not. In most cases, application-specific communication protocols are layered (i.e., carry a payload ) over other general communication protocols . This formidable collection of information technology requires skilled network managers to keep all network systems running well.
2. Introduction LADSE is a Special Education cooperative The building’s featured in this tour are the main administration building and my off-site transition center Jonathan Adamczewski, the IT professional that services LADSE, provided the tour and explanation of LADSE’s network
3. Network Definitions Internet: The global network of networks, composed of hundreds of millions of computers in more than 100 countries. Broadband Router: A device that provides access to the Internet for multiple computers. "Wireless" broadband routers include an 802.11g access point. Notebook: A laptop computer that weighs in a range from five to seven pounds. File Server: A high-speed computer in a network that stores the programs and data files shared by users. It acts like a remote disk drive. Storage: The permanent holding place for digital data, until purposely erased. Ethernet: The standard local area network (LAN) access method. Ethernet is used to connect computers in a company or home network as well as to connect a single computer to a cable modem or DSL modem for Internet access. (Dell, 2005) LAN Switch: A network device that cross-connects clients, servers and network devices. Also known as a "frame switch," stand-alone LAN switches are common in all Ethernet networks. Desktop: A single-user computer. It typically refers to a PC or Mac, but may also refer to Linux PC. Definitions: (PCMAG.COM, 2010)
4. Where it all began... The control room is where the network begins. The phone box in this picture is the original phone system, this is where all of the old phone lines used to enter the building and route out to throughout the building. This box now serves as the entry point for both the phone and internet connections.
5. Where the “new” begins.. From the entry panel, the phone lineis run to the T1 connection which then runs out to the phone gateway. From this point, both the phone system and the internet are connected to the building through a series of switches.
6. Switches, Switches, Switches… The series of switches and Ethernet cables are used to hardwire the building. The LAN consists of computers, printers and the phone system. “The switches are like the tree. Everything branches off of it” Jonathan Adamczewski
7. Servers The servers housed inside the server cabinet store all shared applications as well as storage for employee drives and information. The phone system also stores all voice mail accounts within the servers.
8. Wireless Access (WAN) To provide internet service throughout the building, there are 5 wireless access points used to cover the entire building. These access points are placed to ensure that no dead spots exist. The illustration below shows how wireless coverage should overlap to ensure complete coverage of a building. (Dell, 2005)

10. I learned… That networks, no matter how big or small, play a vital role in how the school system connects its technology. All networks consist of the same basic parts with varying capabilities and numbers of components. Even if it looks like a giant mess, it is all put together in an intricate matter to make the network work to its optimal capacity.
