Cable Modem and DSL Connections to the Internet
Cable modem• Provided by service provider• Has a connection to the TV cable system of your
home that connects to the ISP and an Ethernet port to connect to your PC
• Ethernet cable connects the cable modem to a network card installed in your PC
DSL• A device sits next to your PC, which connects to the
DSL line on one side and to a network card installed in your PC on the other side
17
Examples of Network Services
Most function at top three layers of the OSI model – application, presentation, and session layers
Must be a program running on both nodes of the network for the service to work
17
Upper-level Protocols
Hypertext Transfer Protocol (HTTP)• Used by the World Wide Web
File Transfer Protocol (FTP)• Used to transfer files
Simple Mail Transfer Protocol (SMTP)• Used to transfer e-mail
17
Uniform Resource Locator (URL)
17
World Wide Web Browsers
Provide interface between Web sites and PCs Access a server by either its IP address or its
domain name Use HTTP to request and pass documents on
the Web Terminology
• Hypertext• HTML

File Transfer
File Transfer Protocol (FTP)• Used to transfer files between two
computers using same or different OS Can be initiated at a command prompt
or using an ISP

Network Drive Map
One of most powerful and versatile methods of communicating over a network
Uses network file service (NFS) software to make one PC appear to have a new hard drive
Files and folders on host computer are available even to network-unaware DOS applications

Linux Operating System
Well-suited to support web servers, FTP servers, and file servers
A UNIX-like operating system; can use more than one shell

Linux System Administrator
Installs updates to the OS (patches) Manages backup processes Supports installation of software and
hardware Sets up user accounts Resets passwords Generally supports users Has root privileges

Managing Processes
To initiate a process to run in the background, enter the name of the process at the command prompt followed by “&”
Linux starts the process and responds with a number (the process identifying number, or PID)
To stop a process, use the kill command

Windows Manager
Several applications have been written to provide a GUI shell for UNIX and Linux; these shells are called X Windows

Network Troubleshooting Guidelines
Windows 9x dial-up problems (modem problems)• Cannot make a connection• You can connect, but you get the message “Unable
to resolve hostname…”• After connecting, you get the error message “Unable
to establish a compatible set of network protocols” Problems with TCP/IP
• Problems with TCP/IP configuration or suspected network problems (packet Internet groper or PING)
