3. Computer System
A computer system is a basic,
complete and functional
computer, including all the
hardware and software
required to make it functional
for a user.
It should have the ability to
receive user input, process
data, and with the processed
data, create information for
storage and/or output.

4. Routine Maintenance of Computer
Systems
Definition
Routine Computer maintenance has to do
with regular steps taken to make your
computer work faster, more secure and less
untidy.
Benefits
• prevent future problems like viruses or
data loss,
• free up space
• fix software bugs
• save money
• Save time (improved performance means
less time spent waiting)

5. Computer Maintenance
Symptoms to Watch
• computer seems slow,
• displays an error message about low disk
space
• takes a long time to boot up
Things to Do
• install updates,

• perform other simple tasks like hardware
maintenance to keep your computer in
good shape

Maintenance Practices
Category Sub-category Activities
4 File Management Create and organise
folders and files
Create folders based on the subject of
the files you intend to keep in them.
Don’t clutter the system with files
5 Data backup Backup Regularly copy computer data to
external hardware or save to cloud
which is more secured
6 Hardware
cleanup
Dust, clean Clean and dust internal computer
parts and fan. Use canned air and soft
cloth
7 Disk and
Application/Soft
ware Cleanup
Disk cleanup Go to Start>All
Programs>Accessories>System Tools.
Pick the drive you want to scan (your
main hard drive(s)
Defragmentation program comes with Windows, it’s in
the same place as the Disk Cleanup
tool. It’s a straightforward process;

8. Maintain yourself
• You are a major component of the computer
system that needs to be maintained otherwise
the computer will suffer
• Be in the right frame of mind when using the
computer
• Don’t overstay on the computer, take occasional
break
• Begin shutdown 30 minutes before closing- use
the time to properly shutdown and allow for
updates to be installed and then freshen up your
look and smell nice

9. Basic things to note
• Internet
• World Wide Web
• Search engine

10. The Internet
• The Internet is a collection of vast information
sources of interlinked computer networks
• A network is a computer system that uses
communication equipment to connect two or
more computers and their resources
• The Internet is the largest network
• The Internet is the worldwide, publicly accessible
network of interconnected computer networks
that transmit data by packet switching, using the
standard Internet Protocol suite (IP) to link
devices.

11. Resources and services of the Internet
• Almost everything of interest:
• E-mail,
• World Wide Web,
• Remote access (the Internet allows computer users connect to and use other
computers easily from anywhere in the world),
• voice telephony,
• media streaming, file sharing,
• social networking,
• Webinar (Online seminar),
• Chatting,
• e-commerce,
• e-health,
• e-learning,
• internet banking
• And lots more

12. The World Wide Web
• usually called the Web is the most important service of the
Internet
• The Web consists of a series of various computer
documents, images and other resources logically
interrelated by hyperlinks and referenced with Uniform
Resource Identifiers (URIs).
• The Hypertext Transfer Protocol (HTTP) is the main access
protocol of the Web.
• Browser (e.g. Internet Explorer, Mozilla Firefox, Chrome,
Safari, Opera, etc.) are web software used to navigate the
Web
• Websites are created on the web and each website has its
Uniform Resource Locator (URL) otherwise known as the
website address.

13. Parts of the URL
Uniform Resource Locator (URL) is a specific character string that
constitutes a reference to a resource on the Web. It is the web address of
an online resource, i.e. a web site or document
Three (3) major parts of url:
• (1) Protocol: it declares how your web browser should communicate
with a web server when sending or fetching a web page or document
e.g. http, https, ftp, pop, etc.
• (2) Domain name: a unique reference that identifies a web site on the
internet which always include a TLD or SLD (.edu.ng)
• (3) Path: refers to a file or directory on the web server
Example:
http://www.elizadeuniversity.edu.ng/registry/admissionlist2014.html
In the above example, “http://” is the protocol,
“www.elizadeuniversity.edu.ng” is the domain name, “registry” is the
folder, and “admissionlist2014.html” is the file name which are both path.

14. Internet Search Engines and
Search Strategies
 There are three categories of search tools, namely:
 Search engines
 Directory search
 Meta engine
 Search engines – they are specialized programmes
that assist users to locate information on the web.
 Popular search engines include; Google, Infoseek,
Lycos, Ask.com, Yahoo, Bing, Answers.com,
 Directory search – also known as index search,
Web or Search directory, is the search programme
that produces a directory or list of categories of topics
such as finance, health, news, universities. E.g
DMOZ, The Best of the Web, Yahoo! Directory and
Jasmine Directory

15. Understanding Search Strategy
• Search strategy is a combination of series of
activities that help a researcher find
information from sources

16. Search strategy involves:
• possible search terms
• keywords and phrases
• truncated and wildcard variations of search terms
• subject headings (where applicable)

rching/14/literature_searching_explained/4

17. Developing search strategy
• Start developing a search strategy by identifying the
key words and concepts within your research question.
For example: What strategies can healthcare
workers use to communicate effectively with
clients with a hearing disability?
• Treat each component as a separate concept (there are
usually between 2-4 concepts).
• For each concept list the key words derived from your
research question
• consider singular and plural forms of words, variant
spellings, acronyms and relevant index terms (subject
headings)

19. Search strategy techniques
• Choosing search terms- analyse your research
into concepts
• Searching with keywords- Keywords are free text
words and phrases
• Searching for exact phrases- use quotation marks
• Using truncated and wildcard searches
• Searching with subject headings
• Using Boolean logic (AND, OR, NOT)
• Citation searching

20. Refine your search
Search tips to refine your results
Use a minus sign – in front of a word to require
its exclusion (no space between the sign and the
word).
• Example: –infant

21. Using Truncation and Wildcards to
search for variations (spelling and
form) in words• Truncation
Typing the stem, or root of a word, plus a *, ? or $ symbol at the end of
the word will retrieve all forms of the word
• Example: allerg$ will yield allergy, allergic, allergen
• Example: gastro* will yield gastroenteritis, gastrointestinal,
gastroenterologistWildcard symbols such as a ?
• Wildcard
• May be inserted in place of a letter(s) in a keyword
• Useful when you are not sure of a spelling or when there are
different forms of the root word
• Example: wom?n will yield both woman and women
• Note: symbols used may vary depending on the database or search
engine you are using.

22. Evaluating Your Search Results
• Not every result of search is authentic – therefore,
always check for the following:
• Authority – who writes the article or owns the
material?
• Currency – when last was the page updated? E.g search
Google for “internet penetration in Nigeria” and watch
out for (Nigeria Leads Internet Usage In Africa -
Ventures Africa) http://venturesafrica.com/nigeria-
leads-internet-usage-in-africa/
• Accuracy – is the information reliable and error –free?
• Objectivity – is it free of bias and sentiments?
• Coverage – what is the scope of the resources?

24. Using the library
The OPAC
• The library OPAC is
available at:
http://library.elizadeuniv
ersity.edu.ng/

25. Using the Library
• You can “basic search”
any book or information
item in the OPAC

26. Using the library
• You can do an advanced search and set limits
to specify result
