Differences between Firewall and Antivirus

FirewallAntivirus
A firewall is a security network designed to protect computer systems and networks from malicious attacks. Antivirus is is a software utility program designed to protect a system from internal attacks from viruses, trojan horse, spyware etc
The general term used for a firewall is “packet filter” because it filters any incoming data packets for suspicious contents.Antivirus identifies and corrects any weaknesses found in the computer system.
The main purpose of a firewall is to monitor network traffic and restrict any unauthorized entryThe main function of an antivirus is to scan, detect, prevent and remove any existential threat to the computer system
A firewall works at a network protocol level to safeguard against any unwanted intrusionAn antivirus will  only scan for any harmful programs that are present in the system such as viruses, worms, Trojans etc
One of the limitations of a firewall is that it cannot block any internal attacks and also those attacks that bypass its network coverageOne of the limitations of an antivirus is that it is cannot check read-only files.
DEC SEAL was the first commercially viable firewall program that came out in 1992. Its creation was spearheaded by American computer scientists Brian Reed and Jeff Mogul.The first documented removal of a computer virus was by an actual antivirus software was in 1987 when a German computer security expert, Bernard Robert Fix, created a programme to remove a virus that had infected files in a DOS-based system

COMPUTER GENERTION The modern computer took its shape with the arrival of your time. It had been around 16th century when the evolution of the computer started. The initial computer faced many changes, obviously for the betterment. It continuously improved itself in terms of speed, accuracy, size, and price to urge the form of the fashionable day computer. This long period is often conveniently divided into the subsequent phases called computer generations: First Generation Computers (1940-1956) Second Generation Computers (1956-1963) Third Generation Computers (1964-1971) Fourth Generation Computers (1971-Present) Fifth Generation Computers (Present and Beyond) Before there are graphing calculators, spreadsheets, and computer algebra systems, mathematicians and inventors searched for solutions to ease the burden of calculation.  Below are the 8 mechanical calculators before modern computers were invented. 1. Abacus (ca. 2700 BC) 2. Pascal’s Calculator (1652) 3. Stepped Reckoner (1...
