2. The central processing unit (CPU)
All computations, regulation of data flow, decision-making operation, etc. are carried 
out by this part of the computer. 
The CPU is an important component of the computer system that contains the control 
unit, the arithmetic-logic unit (ALU), and main memory (Primary storage). 
All these parts work together to electronically control the functions of the computer 
system. 
3. Auxiliary (secondary) storage devices: 
To store large amount of information, such as large database, you need auxiliary 
storage devices to supplement the internal memory. Common external storage 
devices include floppy disks (diskettes) and hard disks. 
4. The output unit:
the output unit in a computer system displays the results of 
computations or data processing. Output can be displayed temporarily on a monitor, or 
permanent “hard copy” can be produced on a printer. 
9.2 Introduction to some common software packages 
Word-Processing: 
Microsoft Word is a word-processing program which is used to create and amend files 
containing textual information. It is capable of handling a wide range of applications. It 
is used for the production of simple documents such as letters and it handles complex-
tasks (e.g. production of substantial reports). Before the introduction of Microsoft Word 
there were other word-processing programs like Word star and Word perfect. 
Database: 
In general terms, a database is any ordered collection of information. Thus a 
telephone directory or the list of the university of Gondar students would constitute a 
database.

Research methodology 
104
A typical data set will consist of a collection of cases (or records), each of which 
contains the values of a set of variables (or fields). 
Although it would be possible to write computer programs to organize and analyse a 
file of data, in general Database management systems (DBMSS) are now used. 
These are ready-written, general purpose programs to help in the organization and 
analysis of data. Two examples are: Epi-Info and SPSS. 
I. Introduction to Epi Info 6
• Epi Info is a multi-purpose computer program designed for epidemiological researchers. 
• Within Epi-Info there are smaller programs designed to perform specific tasks. 
→ EPED (questionnaire design) 
→ ENTER (data entry) 
→ CHECK, VALIDATE (data checking) 
→ ANAYSIS (data analysis) 
→ STATCALC (simple statistics) 
→ etc.
