2. Questions:
 What is a Network?
 What types of Networks are there?
 What hardware/software is needed?
 What is necessary for a home network?
 What protocols are used?
 What Broadband options are available?

3. Part 1
 Types of Networks
WAN, LAN, MAN, HAN, PAN (Distance)
Client Server/Peer2Peer (Administration)
 File Sharing (Mac/Win)
 Connecting to the Internet
Broadband Options

4. Network Architectures:
Types of Networks
 Defined by distance and
level of administration
 WAN, MAN, LAN, HAN, PAN
 Client/Server (Central Administration)
 Peer-to-Peer (P2P)
(Local Administration)

5. Network Types:
Defined by Distance

6. Network Types:
Defined by Level of Administration

7. Network Types:
Defined by Level of Administration
 Client/Server – is like our Windows
school network, top down, strictly
managed by IT and networking software
(i.e. Linux, Windows Server).
 Peer 2 Peer – is like a Home Network, or
the Mac Lab – more like a community,
managed by each device individually.

8. Connecting to a Home Network
Windows
Set up in:
Homegroup

9. Connecting to a Home/School Network
Mac OS
Local Computers
In the Finder
School Server
Lab Computer
Set up:
File Sharing

10. Connecting to the Internet
Broadband Internet Options:
 Cable
ISPs: RCN, Comcast, Service Electric
 DSL
ISPs: Verizon, Local Phone Companies
 FiOS – Verizon
 Satellite – DirectTV, Dish
 Mobile Broadband 4G – Verizon, AT&T

11. Broadband Options:
Cable Internet
 Typically the fastest available option
 Download is typically much faster than
upload – 20-50 Mbps vs 5-10 Mbps*
*(megabits per second)
 Speed can vary during peak times or heavy
traffic in your neighborhood
 Bundle with TV, Phone for better pricing

12. Broadband Options
DSL, FiOS, Satellite
 DSL (Digital Subscriber Line) uses 2
additional lines of traditional phone lines
for data. (5-10 Mbps/1Mbps)
 FiOS (Fiber Optic) – uses thin strands of pure
glass or plastic arranged in bundles.
50-500 Mbps, but not as widely available
 Satellite - @ 5-10 Mbps, usually an option
where DSL or cable is not available

13. Other Options
Mobile Broadband, Dial-Up
 Mobile Broadband - sharing or tethering
your computer to your phone connection
Involves a number of concerns, involving data
plans, but may be an alternative option
 Dial-up – painfully slow by todays standards,
was only available option in early web days
(56 Kbps)
