1. INPUTInformation you put into the computer

by way of keyboard, mouse, or stylus.


10/47

2. PROCESSINGAlso known as the "Brain" of the computer.

Processes the information you put in into humanreadable form.

There are three Cs in processing:


11/47

a. CalculateAddition, Subtraction, Multiplication, andDivision


12/47

b. Copyhappens many times with each instruction that is

processed, between registers in the CPU, Devices inthe system, and different addresses in the memory.


13/47

c. ComparingEvery time data is copied, the original data set must be compared

to the new data set and when data is being sorted, values in thedatabase compared to the sort string. When datasets are beingsearched, the database must be compared to the search stream.

I am plotting a graph in microsoftexcel, i am entering the values

(input), the computer will calculatethe values and plot the graph for me(processing), then display the graph

Where did computer virus originate???

Computer viruses originate withprogrammers who write the code. Typically,the code is attached secretly to existing

software, such as popular utility or wordprocessing program. The program is thendisseminated, perhaps via a companyscomputer network or an electronic bulletin

board. Once inside on a new host, the virusreproduces. It may infect any program onany disk used by the system.

1. FILE VIRUSES

are viruses which generally attachthemselves to regular programfiles. They can attach to variouslocations of the original file, replace

code, fill in open spaces in the code, orcreate companion files to work with anexecutable file


26/47

2. BOOT VIRUS

is a virus that infects the part ofthe computer called a system

sector.


27/47

3. MULTIPARTITE VIRUS

combine the abilities of theparasitic and bootstrap sector

viruses and so are able to infecteither files or boot sectors


28/47

4. MACRO VIRUS

is a virus that is written ina macrolanguage: that is to say, a

language built into a software

application such as a word processor.
