SECURITY CONCERNSInternetThree of the many types of Internet security concerns: Malware Virus Trojan horse Worm Phishing SpywareThese can lead to stolen money, yourinformation sold to attackers, andidentity theft. 20. Computer UseThe three main computer usage safety tips:1. Internet security and virus protection program2. Desktop firewall3. Keep operating system updatedTIP: Set your operating system to updateautomatically. 21. The topics covered are Computer science. It is avast and growing field of study. Technology is inconstant motion. We need to keep up.ComputerWWWHardwareSoftwareNetworksInternetOperating systemOSI ModelNetwork TopologiesMalwareFirewall 22. REFERENCESBatra, P. (2010).
