Yes, a virus can be copied.
Viruses, particularly computer viruses, are defined by their ability to replicate themselves. This self-replication is a core characteristic of their nature and functionality. Here's a breakdown:
-
Definition: A virus is essentially a piece of code that can insert itself into other programs or data.
-
Self-Replication: The primary function of a virus is to copy itself. This is what allows it to spread from one computer to another. The referenced text explicitly states that a computer virus can "copy itself to other computers."
-
Mechanism: This copying often happens without the user's knowledge or permission. The virus can attach itself to executables, documents, or even the boot sector of a hard drive.
-
Spread: When the infected file or program is executed on another computer, the virus replicates itself onto that new system.
-
Example: Imagine a virus attached to an email attachment. When you open the attachment, the virus might copy itself to other files on your computer and also send itself to contacts in your address book, thus spreading the infection.
In essence, the ability to be copied is fundamental to the definition and behavior of a virus. Without the ability to replicate, a virus would simply be a piece of inert code.
