Your floppy contains now a Virus Checking Program. The program can be started by typing "a:\f-prot" at the DOS Prompt or in the Windows Run field.
Remarks: It is usually better to save f-prot on a bootable
floppy. http://sckb.ucssc.indiana.edu/kb/data/adav.html explains
how to obtain a bootable floppy. (But that is not rquired for this
Virus Checkers need to be updated frequently. You should obtain a new copy of f-prot every three months.
Write your name on the floppy and give it to your instructor. You will get it back the following week after you handed it in.
2) On the
WWW Viewer Test Page you find information on data formats and "viewers"
(helper applications and plug ins) that allow Web browsers to view
the data formats.
Choose three different computers (eg. MAC and PC in a university lab, PC at home) and ten different data formats (excluding plain text, gif, jpeg) from different data types. For each computer and each format write down (chart table) whether the computer has helper applications or plug ins installed to display the data and which software is used (or could be used if the software is not installed yet).
1) draw circles, lines, squares in vector based and in bitmapped
2) delete, move, copy objects in vector based graphics software?
3) cut, paste, copy blocks in bitmapped graphics software?
4) rotate objects/blocks?
5) change the size of objects/blocks?
6) change colors?
7) group/ungroup objects in vector based graphics software?
8) save the file in different formats?
1) Use several tools for finding people, such as finger, whois, netfind (login as "netfind"), KIS and try to find yourself and another person. Furthermore try to find yourself and the other person on various search engines and internet white pages. Compare.

4) You'll receive an uuencoded file through priss_l401. Uncode it, read it and follow the instructions.
L401 - Computer-Based Information Tools
ERIC Information Retrieval Assignment
A common approach in information retrieval systems is the "building block" strategy, in which
the searcher identifies the basic concepts of the search and selects terms to represent those
concepts. Terms for each concept are combined using logical OR, to "build up" a set of records
relating to that concept. These sets are then combined, generally using logical AND and NOT to
focus retrieval on the topic desired. For this assignment you are to design a search strategy using
the building block approach for a comprehensive search for the following question.
What approaches have been used to assess and improve minority students'
1. Identify the main concepts in the request. Use the Thesaurus of ERIC Descriptors in print and
on CD-ROM as well as preliminary CD-ROM searches to find appropriate descriptors for each
concept. Use Boolean operators to combine the descriptors into concept groups, then to combine
the concept groups. This search should use ERIC descriptors only: no free text terms and no
truncation (this will allow the CD-ROM systems to work faster). Make the search reasonably
2. Use the SilverPlatter CD-ROM system to conduct the search you prepared in step 1. Revise your strategy as needed. When you are satisfied that you have conducted a comprehensive search which retrieved records reasonably relevant to the request print search strategy and the complete records for up to 10 items. (Choose the PRINT option, then select Fields: all, Records: marked, and searches: yes.)
HAND IN: 1) your list of the main concepts for the request
2) your initial plan for the search (the concepts with descriptors and Boolean operators),
3) notes on how (if at all) the initial plan was changed during the search,
4) the printed search strategy
5) the printed list of up to 10 records (complete records)
6) an evaluation of your search addressing these points:
How many records were retrieved?
Was the search a success, in your opinion?
Did you experience any problems? If so, discuss.
How do you rate the ease of use of the SilverPlatter system for
2) Name 5 services on infogate that use the silver platter interface besides ERIC.
3) Go to the Clearinghouse for Subject-Oriented Internet Resource Guides (http://www.clearinghouse.net) and find an internet resource on "knots". Write down the url of that resource.
4) In the UnCover (CARL) service on infogate: what is the total delivery cost for obtaining Thom Nisonger's article "Book Evaluation Discussion Groups".
5) Library of Congress Service (http://www.loc.gov): Find the LC number (using the advanced search form) for Mark Twain's Huckleberry Finn which was edited by Emily Fanning Barry and Herbert B. Bruner. Print the full (long) record of this book.
6) On AltaVista do a search on "syndetic". Look at the Topic Relationships under "Visual Live Topics". Which three main concepts are connected to each other in the diagram? Why are the three concepts related to "syndetic"? (Remark: you have to use a Java enabled browser for this exercise.)
7) For the IAC (InfoTrac) databases, in the Expanded Academic Index, find an article about the recent cult suicides in Quebec and find an article in Forbes about Apple's recent stock woes. Write down the titles of those articles.
Modify the menu options:
1) show a long listing of the content of your home directory
2) invoke the pico editor
3) show all users who are currently logged into the computer
4) more the ".login" (or the ".profile") file in your home directory
Remember to change not only the unix commands, but also the information which is displayed to the user of the menu.
Try what happens if you remove the "read dummy" commands (do not also remove the ";;" signs). Why does it seem to be a good idea to remove the "read dummy" commands for option 2) and 4) but not for 1) and 3)?
Email an answer to this question together with a copy of your program to your lab instructor.
2) Write a script which lets the user choose between two options (such as listing the directory or displaying the date). Use a "if then else fi" statement for this script.
3) (This assignment cannot be handed in.) If you use a modem at home and connect to the university through the ppp connection, have a look at the login script and try to change the phone-numbers in that script. Remember to copy the script before you make changes!
4) (This assignment cannot be handed in. For Bloomington students only.) Have a look at the scripts /usr/local/bin/menu and /usr/local/bin/open_menu on ezinfo.
Make sure you have 12 columns for the months, and several rows for categories you include figures on for each month (3-6 categories). Add another column with the sums for each row, and put sums at the bottom of each column.
2) Create a column chart for your data using
side-by-side columns. Either:
a) Do each month, with side-by-side category bars for each category, or
b) Do each category, with all 12 months as side-by-side bars in each category.
Use appropriate labels for the chart (x-axis, y-axis, title etc.)
1) a printout of the spreadsheet
2) a printout of the chart (as a separate file)
a) Explain how databases can be distinguished according to their types, their content, and their structures.
b) List several different phases involved in database design.
2) Design three small tables for a library database. For example, one table could contain information on the books of the library, another could contain information on the patrons. Insert 5 sample records into each of your tables.
