HOW DOES A NETWORK WORK?JILL BOWMANETEC 5303FEBRUARY 5, 2017

LEARNING OBJECTIVES•At the conclusion of this presentation, students will be able to…• Identify all of the hardware needed to make a

network function. • Explain how information travels throughout a

network.

ISTE STANDARDS

4. Professional Development and Program Evaluation • Technology coaches conduct needs assessments, develop

technology-related professional learning programs, and evaluate the impact on instructional practice and student learning. • b. Design, develop and implement technology-rich professional

learning programs that model principles of adult learning and promote digital age best practices in teaching, learning and assessment.

FLOW OF INFORMATIONThis graphic shows how information moves between the different parts of a network. You will learn about these parts in detail in this presentation.

COMPUTER WORKSTATION• Workstations are “hard-wired”

meaning they must be connected to the network with a physical cable. • This is the piece of hardware

you use to access the network.

CAT 5/6 CABLE

• Better known as an Ethernet cable. • Used to connect all the

elements of the network. • Information goes from a

computer to the next step via the Cat 5 cable.

SWITCH/HUB

• Acts as an extender to the router providing additional ports.• Information goes through the switch on the way to the next

step. • A Switch is a special kind of hub that can send information to

specific locations.

ROUTER• Directs information to either the internet or

the main server.• Contains firewall to block unwanted devices. • You can block websites using router software. • Assigns devices IP addresses – unique

location assigned to each device that uses the internet.

INTERNET

• Used for instant communication with devices all over the world• Email, web browsing, streaming• This is a WAN – Wide Area Network• Multiple browsers available such as

Chrome, Firefox, Safari, and Internet Explorer

MAIN SERVER• Storage of all shared files and

programs. • Huge amounts of data storage.• Connection to the server allows you

to access printers in another location entirely. • Does not require internet. • Sometimes referred to as Intranet.

LAN

• LAN – Local Area Network• These are computer and devices just in your building or

home.

SPEED OF INFORMATION

• More devices connected = more people sharing the same pathways = slower response time• This is especially true when using the internet. • School and business network speed is often slow because the

bandwidth is shared among so many devices.
