I will tell you what is firewall in networking. There are many different types of Networking Firewalls and each has their own advantages and disadvantages. Many businesses use software firewalls to help prevent unauthorized access to their company data or network. Most software-based firewalls provide the basic security required but do not have all the bells and whistles that other hardware firewalls provide. Software-based firewalls can be set up in minutes and will not require any knowledge of the inner workings of your computer or network to work effectively.
