Answer 1

(1) VIRUS
A computer virus is a type of malicious software program that, when executed, replicates itself by modifying other computer programs and inserting its own code.

(2)HTTP
The Hypertext Transfer Protocol is an application protocol for distributed, collaborative, and hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web.

(3)ANTIVIRUS SOFTWARES
Antivirus or anti-virus software, sometimes known as anti-malware software, is computer software used to prevent, detect and remove malicious software.

(4)IMAP
IMAP (Internet Message Access Protocol) is a standard email protocol that stores email messages on a mail server, but allows the end user to view and manipulate the messages as though they were stored locally on the end user's computing device(s). This allows users to organize messages into folders, have multiple client applications know which messages have been read, flag messages for urgency or follow-up and save draft messages on the server.

(5)DATA BACKUP
A data backup is the result of copying or archiving files and folders for the purpose of being able to restore them in case of data loss.
