FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Firewalls provide protection against outside cyber attackers by shielding your computer or network from malicious or unnecessary network traffic. Firewalls can also prevent malicious software from accessing a computer or network via the internet.

Detailed explanation-2: -A network firewall is a security device that monitors all incoming and outgoing traffic on a private network. Network firewalls work like device-specific firewalls, but they protect an entire network by blocking unauthorized access, which protects all the devices connected to that network.

Detailed explanation-3: -How do firewalls work? A firewall decides which network traffic is allowed to pass through and which traffic is deemed dangerous. Essentially, it works by filtering out the good from the bad, or the trusted from the untrusted.

Detailed explanation-4: -By filtering this data, the firewall can determine if traffic is legitimate and if it should be allowed through to its end destination. For example, if content filtering is enabled, the firewall will identify traffic coming from an unauthorized website-usually via IP addresses-and block access, notifying the end user.

Detailed explanation-5: -A firewall is a component that is used to monitor the incoming and outgoing traffic in a network. The term ‘firewall’ can be used to refer to hardware or software. Firewalls can be used to limit access to internal networks and protect them from internal and external dangers.
