Goal: The purpose of this laboratory exercise is to introduce some
capabilities of MathLAN and the World Wide Web.
Log onto the HP system.
Prepare to utilize the World Wide Web by clicking on the Netscape icon
(the picture with N at the bottom panel of the screen).
View the MathLAN home page by clicking the mouse on the Netscape
window, when it appears.
Practice scrolling material shown in the window up and down:
Scroll down by moving the mouse to the bottom part of the scroll
bar and clicking the left mouse button.
Scroll up by moving the mouse to the top part of the scroll
bar and clicking the left mouse button.
Move up or down by moving the mouse to the shaded part of the
scroll bar, holding the middle mouse button down, and sliding the mouse up
and down.
Practice moving and resizing the Netscape window.
Move the Netscape window by moving the mouse to the labeled bar
near the top of the window, depressing the left mouse button, and dragging
the window around the screen.
Resize the Netscape window by moving the mouse to the small border
of a window or to the small corner border, pressing the left mouse button,
and moving the border to a new position.
If you wish, you may change your password by typing password in
an hpterm window. (If no hpterm window currently is
visible, you may create one by clicking on the picture of a terminal, found
on the bottom control panel.) After you have typed password in the
hpterm window, the machine will ask you for your old password and
your desired new one.
Scrolling down the home page for the Mathematics and Computer Science
Deprtment, click on the line The Mathematics Local-Area Network
(MathLAN) in the Computer resources section. Next click on the
GCCS computer use policies link, to read the current rules and
regulations regarding the use of computers at Grinnell College.
Go back to the Mathematics and Computer Science Home Page for
Grinnell College by clicking on the Back button at the top of the
Netscape window. Now follow the links to ``Faculty'', then ``Henry
Walker''.
Scroll down to find the link Computer Science Tutorial: Computing:
Limitations and Promising Developments to find basic information for
this course. Then click on Labs and Lab 1 to find this lab.
Move back to the MathLAN Home Page. Then, scroll down to find the
entry Grinnell College front door, and click the left mouse button
on this entry.
Explore the Grinnell College Home Page, by clicking on various
highlighted entries. For example, find Campus Offices,
then Registrar, then 1997-98 Schedule of Courses Information,
and finally Fall 1997 Final Examination Schedule to determine when
the Tutorial's final exam would be (if the course were to have a final
exam).
Move back to the Grinnell College Home Page by clicking on the Back
button at the top of the Netscape window. (You will need to go back several
screens, so click Back several times.)
Investigate access to Burling Library by clicking on Campus Links
and then the hypertext version of the library catalog.
Try accessing the library catalog by clicking on Library
Catalog.
Check for all books by Jack Copeland, by clicking on an author search
copeland, jack
Prepare for a new search by going back to the Library Catalog .
Now check for all books with the title, ``The Limits of
Computing,'' by clicking on a title search and entering limits of
computing
Experiment with other options in the catalog.
Finish with the catalog window by returning to the Campus Links page.
Try searching the internet for information on the United Nations.
To do this, first use the general search resource called
``Yahoo!'' by clicking on the Internet Search Engines link on the
Grinnell College Library page and then choosing YAHOO.
Yahoo! is such a commonly used resource in searching the internet
that you may want to save this location for further reference. To do this,
once you have the Yahoo screen visible, click the left mouse button on the
``Bookmarks'' menu at the top of Netscape. Then click the left button on
the ``Add Bookmark'' option. Hereafter, you can get to ``Yahoo!'' by
opening the Bookmark menu and selecting ``Yahoo!'' directly.
Within Yahoo!, search for material on the United Nations by typing
``United Nations'' in the Yahoo search window.
Now follow links to Fifty Years of the UN, particularly the account
by the CNN news organization. Try to determine how many UN Peacekeeping
Forces activities are currently active.
Also, find the United Nations Home Page.
Use the Yahoo! search engine to find out something about at least two
businesses from Guaynabo Puerto Rico, Lviv Ukraine, and Dar es Salaam Tanzania.
(In each case, you might try searching by city and country, and then
following links you think might be productive. In some cases, you may want
to extend your search with another search engine, such as Alta
Vista.)
Go back to the Mathematics and Computer Science Home Page for
Grinnell College. Now follow the links to ``Faculty'', then ``John Stone''
and ``a collection of links''.
Follow the link People Search, in the ``Search tools'' section, and
use the Lycos and People Find links. Within Iowa,
search for the name ``Henry Walker''.
Click on my address to get further information; locate my address on a
map. Then zoom out several times to find where our house is with relation
to the midwestern United States.
If your parents live in the United States, try looking them up in
Lycos. If not, try looking up a relative or talk to someone else in
the class to look up their parent(s).
