2. Networking Fundamentals
Network: two or more computers that are connected via software and hardware so they can communicate with each other
Node: each device that is connected to a network
Throughput: speed of data transferred (Mbps)
A computer network is simply two or more computers that are connected via software and hardware so they can communicate with each other.
Each device that is connect to the network is call a node
Ex. Computer, printer, game console
The way data is transferred between devices is called throughput which is the speed that data is transferred.
This speed is measured in Megabits per second (MBSP)
1 Megabit= 1 million bits

3. Pros and CONS of Networks
Benefits:
Sharing Internet Connection
Sharing printers and other peripheral devices
Sharing Files
Common Communication
Disadvantages:
Large networks can be costly and require a network administration
Benefits
Sharing Internet connection- sharing high speed internet
Sharing Printers and other peripheral devices- ex. Multiple computers can print to the same printer without being connected by a wire
Sharing files- share files without using portable devices like flash drives
Common communications- running different operating systems can communicate on the same network
Disadvantages:
Network administration costs a lot of money but is necessary to
install new computers and devices
Monitor the network to ensure it’s performing efficiently
Updating and installing new software on the network
Setting up proper security

4. 5 Network Types WAN MAN LAN HAN PAN WAN- Wide Area Networking
MAN- Metropolitan Area Networking
LAN- Local Area Networking
HAN- Home Area Networking
PAN- Personal Area Networking
Lexi Becker

5. Wide area networking WAN Wide Area Networking Covers the world
Networked collection of local area networks
Lexi Becker

6. Metropolitan Area Networking
MAN
Metropolitan area networking
Specific geographic areas
Internet access to residents and tourist
Lexi Becker

7. Local Area Networking LAN Local area networking Small geographic area
Schools, restaurants, businesses
Lexi Becker

8. Home Area Networking HAN Home area networking Located in home
Connect all of the home’s digital devices
Lexi Becker

9. Personal Area Networking
PAN
Personal area networking
Communication among devices close to one person
Using Bluetooth and WIFI

10. Levels of Administration
Networks need to be managed in one of two ways
1. Centrally
2. Locally
Lexi Becker

11. Central Administration
Central Administration: tasks performed on one computer affect the other computers on the network
Client/server network:
Client: computer used to complete tasks and make requests
Server: computer that provides information or resources to client computers
Central Administration: tasks performed on one computer affect the other computers on the network
Client/server network:
Client: computer used to complete tasks and make requests
Server: computer that provides information or resources to client computers
These networks have 10 or more nodes
Lexi Becker

12. Local Administration
Local Administration: the configuration and maintenance of the network must be performed on each individual computer on the network
Peer-to-peer network: each node connected on the network can communicate directly with every other node on the network
Local Administration: the configuration and maintenance of the network must be performed on each individual computer on the network
Peer-to-peer network: each node is connected on the network can communicate directly with every other node on the network
Cost less than centrally located networks
Common in homes and small school and offices

13. Wired Networks
Fiber-optic: plastic or glass fibers that transmit data at extremely fast speeds
Twisted-pair: copper wires that are twisted around each other and surrounded by plastic jacket
Coaxial: consist of a single cooper wire surrounded by layers of plastic
Wired networks use various types of cables to connect nodes.
The type of network and distance between nodes will determine the type of cable that is used
Fiber-optic: plastic or glass fibers that transmit data at extremely fast speeds(HIGHLIGHT)
Twisted-pair: copper wires that are twisted around each other and surrounded by plastic jacket
Ex. Telephone cable(WRITE PHONE)
Coaxial: consist of a single cooper wire surrounded by layers of plastic

14. Internet
Broadband- type of connection that offers a means to connect to the Internet with faster throughput
Broadband- type of connection that offers a means to connect to the Internet with faster throughput
Data transmission rate ranges from 1 to 500 Megabits per second
DSL is the slowest and Fiber-optic is the fastest
Lexi Becker

15. Net Neutrality
Net Neutrality is the idea that data on the internet is treated equally, meaning there is no differential by the type of user, the content that is being uploaded or by the mode of transfer.
Net Neutrality is the idea that data on the internet is treated equally, meaning there is no differential by the type of user, the content that is being uploaded or by the mode of transfer.
So no matter what kind of broadband internet you are using you should receive your internet data the exact same…. With the understanding that some broadband’s throughput will be slightly different

16. Questions
1. Computer Network: two or more computers that are connected via software and hardware so they can communicate with each other
2. Fiber-optic, twisted-pair, and coaxial cables
Fiber-optic: plastic or glass fibers that transmit data at extremely fast speeds
Twisted-pair: copper wires that are twisted around each other and surrounded by plastic jacket
Ex. Telephone cable
Coaxial: consist of a single cooper wire surrounded by layers of plastic
3. Bandwith is another name for data transfer rate
4. Throughput is the actual speed of data transfer
Throughput is measured in megabits per second (MBPS)
5. Network Neutrality: data on the internet is treated equally, there is no differential by the type of user, the content that is being uploaded, or by the mode of transfer

17. Questions continued
5. Network Neutrality: data on the internet is treated equally, there is no differential by the type of user, the content that is being uploaded, or by the mode of transfer
6. Networks are classified by the DISTANCE BETWEEN THEIR NODES
Five types of Networks
WAN- Wide Area Networking (world…the Internet)
MAN- Metropolitan Area Networking (city)
LAN- Local Area Networking (business or school)
HAN- Home Area Networking (home)
PAN- Personal Area Networking (smartphone)
