Big Dummy's Guide To The Internet by Electronic Frontier Foundation (early reader chapter books .txt) ๐
When you tell your communications software to capture a screen, it opens a file in your computer (usually in the same directory or folder used by the software) and "dumps" an image of whatever happens to be on your screen at the time.
Logging works a bit differently. When you issue a logging command, you tell the software to open a file (again, usually in the same directory or folder as used by the software) and then give it a name. Then, until you turn off the logging command, everything that scrolls on your screen is copied into that file, sort of like recording on videotape. 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

Each line represents a different database (the .au at the end of some of
them means they are in Australia; the .fr on the last line represents a
database in France). And this is just the first page! If you type a
capital K, youโll go to the next page (there are several pages).
Hitting a capital J will move you back a page.
The first thing you want to do is tell the WAIS program which
databases you want searched. To select a database, move the cursor bar
over the line you want (using your down and up arrow keys) and hit your
space bar. An asterisk will appear next to the line number. Repeat this
until youโve selected all of the databases you want searched. Then hit
your W key, after which youโll be prompted for the key words youโre
looking for. You can type in an entire line of these words โ separate
each with a space, not a comma.
Hit return, and the search begins.
Letโs say youโre utterly fascinated with wheat. So you might select
agricultural-market-news to find its current world price. But you also
want to see if it has any religious implications, so you choose the
Bible and the Book of Mormon. What do you do with the stuff? Select
recipes and usenet-cookbook. Are there any recent Supreme Court
decisions involving the plant? Choose supreme-court. How about synonyms?
Try roget-thesaurus and just plain thesaurus.
Now hit w and type in wheat. Hit enter, and the WAIS program begins
its search. As it looks, it tells you whether any of the databases are
offline, and if so, when they might be ready for a search. In about a
minute, the program tells you how many hits itโs found. Then you get a new
menu, that looks something like this:

Each of these represents an article or citing that contains the word wheat,
or some related word. Move the cursor bar (with the down and up arrow
keys) to the one you want to see, hit enter, and it will begin to appear
on your screen. The โscoreโ is a WAIS attempt to gauge how closely the
citing matches your request. Doesnโt look like the Supreme Court has had
anything to say about the plant of late!
Now think of how much time you would have spent logging onto various
databases just to find these relatively trivial examples.
8.6 THE WORLD-WIDE WEB
Developed by researchers at the European Particle Physics
Laboratory in Geneva, the World-Wide Web is somewhat similar to a WAIS.
But itโs designed on a system known as hypertext. Words in one document
are โlinkedโ to other documents. Itโs sort of like sitting with an
encyclopedia โ youโre reading an article, see a reference that
intrigues you and so flip the pages to look up that reference.
To try the Worldwide Web, telnet to
ukanaix.cc.ukans.edu
Log on as: www. When you connect, youโll see something like:

8.7. CLIENTS, OR HOW TO SNARE MORE ON THE WEB
If you are used to plain-vanilla Unix or MS-DOS, then the way these
gophers and WAISs work seems quite straightforward. But if youโre used
to a computer with a graphical interface, such as a Macintosh, an IBM
compatible with Windows or a Next, youโll probably regard their
interfaces as somewhat primitive. And even to a veteran MS-DOS user, the
World-Wide Web interface is rather clunky (and some of the documents and
files on the Web now use special formatting that would confuse your poor
computer).
There are, however, ways to integrate these services into your
graphical user interface. In fact, there are now ways to tie into the
Internet directly, rather than relying on whatever interface your
public-access system uses, through what are known as โclientโ programs.
These programs provide graphical interfaces for everything from ftp to
the World-Wide Web.
There is now a growing number of these โclientโ programs for
everything from ftp to gopher. PSI of Reston, Va., which offers
nationwide Internet access, in fact, requires its customers to use these
programs. Using protocols known as SLIP and PPP, these programs
communicate with the Net using the same basic data packets as much larger
computers online.
Beyond integration with your own computerโs โdesktop,โโ client
programs let you do more than one thing at once on the net โ while youโre
downloading a large file in one
