video tape. This is useful for capturing long documents that scroll for several pages –
using screen capture, you would have to repeat the same command for each new
screen.
Terminal emulation is a way for your computer to mimic, or emulate, the way
other computers put information on the screen and accept commands from a
keyboard. In general, most systems on the Net use a system called VT100.
Fortunately, almost all communications programs now on the market support this
system as well – make sure yours does.
You'll also have to know about protocols. There are several different ways for
computers to transmit characters. Fortunately, there are only two protocols that you're
likely to run across: 8-1-N (which stands for «8 bits, 1 stop bit, no parity» – yikes!)
and 7-1-E (7 bits, 1 stop bit, even parity).
In general, Unix-based systems use 7-1-E, while MS-DOS-based systems use 8-
1-N. What if you don't know what kind of system you're connecting to? Try one of
the settings. If you get what looks like gobbledygook when you connect, you may
need the other setting. If so, you can either change the setting while connected, and
then hit enter, or hang up and try again with the other setting. It's also possible your
modem and the modem at the other end can't agree on the right baud rate. If changing
the protocols doesn't work, try using another baud rate (but no faster than the one
listed for your modem). Again, remember, you can't break anything.! If something
looks wrong, it probably is wrong. Change your settings and try again. Nothing is
learned without trial, error and effort. Those are the basics. Now onto the Net!

1. Point out what you consider to be new or important information for you.
2. Find the passage dealing with modem and sum up the information about it.
3. Write abstract of the text.

Read the text and speak about the Internet sites.
PUBLIC-ACCESS INTERNET SI TES
What follows is a list of public-access Internet sites, which are computer
systems that offer access to the Net. All offer international e-mail and Usenet
(international conferences). In addition, they offer:
FTP
File-transfer protocol – access to scores of file libraries (everything from
computer software to historical documents to song lyrics). You'll be able to
transfer these files from the Net to your own computer.
