What are my Choices for Connecting to the Internet?
- Shell Account
- SLIP/PPP Account
What is a Shell Account?
- Text only. No graphics.
- Your computer dials into a "host" computer that is a part
of the Internet.
- Your computer never becomes a part of the Internet. It just acts as
a "dummy" terminal to the host computer.
- You do not have access to the data on your hard disk drive and floppy
disks while connected.
- Software needed: A communications program that can dial out. Ex.
ProComm, Telix
- Where to get a shell account: Internet Service Provider, Colleges and
other organizations you may
be a part of.
- Cost: $5 to $20 per month.
- You don't need a powerful computer. Almost any computer will do.
What is a SLIP/PPP Account?
- Provides a graphical user interface to the Internet.
- Your computer dials to a "gateway" computer that is a part
of the Internet.
- Your computer becomes part of the Internet while connected.
- You have full access to date on your hard drive and floppy disks while
connected.
- Software Needed:
Your Provider should send disks to get
connected. Make sure they send
directions on how to install.
- Where to get a SLIP/PPP Account: Internet Service Provider
- Cost: $7 - $30 per month. For $20, you should be able to get unlimited
access.
What is SLIP/PPP?
SLIP and PPP are two slightly different ways to connect to the Internet
through a normal telephone line
They make it possible for your computer to become part of the Internet.
If you get a choice between SLIP or PPP, choose PPP. It supports error
correction.
Steps in Getting Yourself Connected to the Internet with a SLIP/PPP
Account
- Make sure you have the right hardware (computer, modem, phone line).
- Locate a Provider who:
- provides a local access phone number
- provides good technical support
- is recommended by someone
- Call the Provider to get:
- information about their montly rates
- information on connect time allowed
- the telephone number that you would use to connect
- information about technical support... Is that number local? Toll
free?
Hours of Service?
- Call the operator to verify the numbers the provider gave you are in
fact local.
- Call the provider to signup and have them send you the necessary
software
on diskettes with instructions.
- Follow the instructions provided with the software to install it and
configure it (more later).
- Call the provider if there are problems. It can save you a lot of
time.
What you Need to Make a SLIP/PPP Connection
Computer
- 486 or Pentium is recommended. A 386 will do.
- 8 megabytes of RAM. 16 is preferred.
OR
- Macintosh with 68030 processor
- 8 megabytes of RAM
- HD Superdrive
- 10 -12 megabytes of free hard disk space
- System 7 or higher
Windows (not for Macintosh)
Windows 3.1, 3.11, 95 (Need 16 Megs of RAM), NT (same)
Modem
For connecting your computer to a phone line.
The faster the better (14.4, 28.8, 33.6, 56.6 Kbps)
Phone Line
If the line has call waiting feature, learn how to disable it.
Software that does SLIP/PPP
Example: Trumpet Winsock is Freeware that can be used for Windows 3.1
Windows 95 and NT have this software built-in
Mac users can try MACPPP
Tools to Ask for
- Browser (Either Netscape, Internet Explorer or even Mosaic will be
OK)
- Email
- FTP (file transfer protocol)
- Newsgroups
- Telnet
- IRC (internet relay chat) optional
SLIP/PPP Account with a Commercial or Internet Service
Provider
Amercia Online, Compuserve, Prodigy, AT&T, MCI, Sprint, INJersey,
etc...
Helpful Hints
- Avoid 1 year contracts.
- Beware of hourly connection rates. They can add up.
- Keep the number of your Internet Service Provider handy.
- Call the provider when necessary.
- If you are using a credit card to make monthly payments to the
provider,
make sure you monitor your monthly statements.
- If the diskettes from the provider have been sitting around a while,
don't use them to install software on your computer. Ask the provider to
send you a new set of diskettes.
- If you already have some type of Internet software installed (AOL,
Compuserve, VersaTerm Links, etc...), it may conflict with your new
communication
software. If this is the case, call your new provider to help you
troubleshoot.
Usually it involves deleting your previous software.
