//Router vs firewall, another article that will put together two different technologies and see what they are good at. We will see another aspect of the “router vs firewall” too, which is the hardware firewall of a router vs a software firewall. Let’s begin.

//You want to create a network for the computers in the office, but you don’t know what to choose – a hub or a switch.

//Many network administrators use the traceroute command daily. It is a convenient tool that you can use under different operation systems – Windows (Tracert), MacOS, Linux (traceroute) and even on mobile (Android and iOS).
You can use traceroute, and see the full route that the packets take to their destination (domain or IP address). Apart from that, you will see the hostnames and IPs of the routers on the way and the latency, the time it takes for each device to receive and resend the data.
You can see which gateway is discarding your data and later you can fix it.
//Ping is a very universal command between all the operating systems. You can use it to test if you can reach your target and how much time it will take to do it. Ping sends Internet Control Message Protocol (ICMP) packets to the destination. Then it waits for the echo reply. It can show statistic for this request, errors and packet loss.
When you use this command, you will send few echo requests, usually 4. Then you will receive a result for each of them, that indicates if they were successful, how much data was received, the time it took for the response and TTL (Time to live).
