Detailed explanation-1: -Unlike routers and switches, firewalls are network security appliances. While routers (without firewall capabilities) blindly pass traffic between two separate networks, firewalls monitor the traffic and helps block unauthorized traffic coming from the outside trying to get into your network.
Detailed explanation-2: -HOP counts refer to the number of devices, usually routers, that a piece of data travels through. Each time that a packet of data moves from one router (or device) to another-say from the router of your home network to the one just outside your county line-that is considered one HOP.
Detailed explanation-3: -In wired networks, the hop count refers to the number of networks or network devices through which data passes between source and destination (depending on routing protocol, this may include the source/destination, that is, the first hop is counted as hop 0 or hop 1).
Detailed explanation-4: -However, the easiest way to get a hop count is by using a command, called tracert, that comes with Command Prompt in every version of Windows. Open Command Prompt and then execute tracert followed by the hostname or IP address of the destination, such as tracert lifewire.com.
