A Computer Virus cannot be contracted by which of the below.
-
Floppy diskette
-
E-mail
-
Scanner
-
Internet Downloads
A scanner is an input device that converts physical documents to digital format. Unlike floppy disks, email attachments, or internet downloads, scanners do not execute or transfer executable code - they only create image files. Therefore, a computer virus cannot be contracted from a scanner alone.
To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) Floppy diskette - This option is incorrect because computer viruses can be contracted through infected floppy diskettes. In the past, floppy diskettes were a common way for viruses to spread from one computer to another.
Option B) E-mail - This option is incorrect because computer viruses can be contracted through infected email attachments. Opening or downloading a malicious attachment can infect your computer with a virus.
Option C) Scanner - This option is correct. Scanners are hardware devices used for scanning physical documents or images into digital format. They do not have the capability to contract or spread computer viruses. However, it's worth noting that if the scanned document or image contains a virus, the virus may become active once the scanned file is opened on the computer.
Option D) Internet Downloads - This option is incorrect because computer viruses can be contracted through infected files downloaded from the internet. Downloading files from untrusted or malicious websites can put your computer at risk of getting infected with a virus.
The correct answer is C) Scanner. Scanners do not have the capability to contract or spread computer viruses.
