Study Notes
Connecting Your LAN to the Internet
- Even if private networks use the same IP addresses, they do not cause problems because they use different public IP addresses.
- The modem/router gets the public WAN-IP address when it connects to the ISP.
- The modem/router assigns private network addresses to systems connected to it.
- It uses NAT to replace the private IP address used by a system on the LAN with the Internet-addressable IP address.
Viewing Your Public IP Address
- You can find out your public IP address by visiting a Web-based IP address lookup service, such as WhatIsMyIPAddress.com.
- You can also visit http://get-site-ip.com or www.myipaddress.com.
Wired Connection - Ethernet
- A wired connection to a LAN is called an Ethernet connection.
- Ethernet cables are used to connect computers and other devices to wired connection points in your network.
- Ethernet cables are made in different grades or categories called Category 5 or “Cat” 5.
- Ethernet cables can reliably transmit signals over a cable length of about 300 feet (100 meters).
Wireless Connection - Wi-Fi
- Wi-Fi, or wireless fidelity, is a standard for wireless networking that uses radio waves to transfer data between computers and other devices.
Cellular Networks
- Cellular service travels with you and is available anywhere your provider has a cell network.
- Your phone can roam and use services from another carrier if you leave your provider’s coverage area.
Cellular Carriers
- Cellular carriers are cell phone companies that provide cellular service to mobile phone users.
- AT&T, Sprint, T-Mobile, and Verizon are the four biggest cell carriers in the USA.
- GSM carriers use GSM networks and their phones identify with the carrier network through the use of a SIM card.
- CDMA carriers use CDMA networks and CDMA phones use an ESN (Electronic Serial Number) to identify with the carrier network.
- Pre-Paid Carriers charge an up-front fee for services and are run by either a CDMA or GSM carrier or a third-party carrier who “piggybacks” services off a major carrier network.
Obtaining Cell Service
- Pre-Paid services provide cellular service on a month-to-month basis and do not require users to sign a contract.
