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

HYTELNET 6.2 was written by Peter Scott,
U of Saskatchewan Libraries, Saskatoon, Sask, Canada. 1992
Unix and VMS software by Earl Fogel, Computing Services, U of S 1992
The first choice, โโ will be highlighted. Use your down
and up arrows to move the cursor among the choices. Hit enter when you
decide on one. Youโll get another menu, which in turn will bring up
text files telling you how to connect to sites and giving any special
commands or instructions you might need. Hytelnet does have one quirk.
To move back to where you started (for example, from a sub-menu to a
main menu), hit the left-arrow key on your computer.
Play with the system. You might want to turn on your computerโs
screen-capture, or at the very least, get out a pen and paper. Youโre
bound to run across some interesting telnet services that youโll want to
try โ and youโll need their telnet โaddresses.โโ
As you move around Hytelnet, it may seem as if you havenโt left
your host system โ telnet can work that quickly. Occasionally, when
network loads are heavy, however, you will notice a delay between the
time you type a command or enter a request and the time the remote
service responds.
To disconnect from Hytelnet and return to your system, hit your q
key and enter.
Some telnet computers are set up so that you can only access them
through a specific โport.โ In those cases, youโll always see a number
after their name, for example: india.colorado.edu 13. Itโs important to
include that number, because otherwise, you may not get in.
In fact, try the above address. Type
telnet india.colorado.edu 13
and hit enter. You should see something like this:
Trying 128.138.140.44 โฆ
Followed very quickly by this:
telnet india.colorado.edu 13
Escape character is โ^]โ.

What we want is the middle line, which tells you the exact
Mountain Standard Time, as determined by a government-run atomic clock
in Boulder, Colo.
6.2 LIBRARY CATALOGS
Several hundred libraries around the world, from the Snohomish
Public Library in Washington State to the Library of Congress are now
available to you through telnet. You can use Hytelnet to find their
names, telnet addresses and use instructions.
Why would you want to browse a library you canโt physically get to?
Many libraries share books, so if yours doesnโt have what youโre looking
for, you can tell the librarian where he or she can get it. Or if you live
in an area where the libraries are not yet online, you can use telnet to do
some basic bibliographic research before you head down to the local branch.
There are several different database programs in use by online
libraries. Harvardโs is one of the easier ones to use, so letโs try it.
Telnet to hollis.harvard.edu. When you connect, youโll see:
H A R V A R D U N I V E R S I T Y OFFICE FOR INFORMATION TECHNOLOGY *** *** VE *** RI *** *** *** HOLLIS (Harvard OnLine LIbrary System) ***** TAS **** HUBS (Harvard University Basic Services) *** IU (Information Utility)CMS (VM/CMS Timesharing Service)
HOLLIS IS AVAILABLE WITHOUT ACCESS RESTRICTIONS **Access to other applications is limited to individuals who have been
granted specific permission by an authorized person.
To select one of the applications above, type its name on the command
line followed by your user ID, and press RETURN.
HOLLIS DOES NOT REQUIRE A USERID **EXAMPLES: HOLLIS (press RETURN) or HUBS userid (press RETURN)
===>
Type
hollis
and hit enter. Youโll see several screens flash by quickly until finally the
system stops and youโll get this:
WELCOME TO HOLLIS
(Harvard OnLine Library Information System)
To begin, type one of the 2-character database codes listed below:
HU Union Catalog of the Harvard libraries
OW Catalog of Older Widener materials
LG Guide to Harvard Libraries and Computing Resources
AI Expanded Academic Index (selective 1987-1988, full 1989- )
LR Legal Resource Index (1980- )
PA PAIS International (1985- )
To change databases from any place in HOLLIS, type CHOOSE followed by a
2-character database code, as in: CHOOSE HU
For general help in using HOLLIS, type HELP. For HOLLIS news, type
HELP NEWS. For HOLLIS hours of operation, type HELP HOURS.
ALWAYS PRESS THE ENTER OR RETURN KEY AFTER TYPING YOUR COMMAND
The first thing to notice is the name of the system: Hollis.
