PING - is one of the most basic tools for testing connectivity to other hosts. It sends an internet control message protocol (ICMP) echo request to a host and listens for the reply Traceroute/tracert - are used to trace the route an IP packet takes to a destination. It displays each hop (next router) in a numerical list with the hop's IP address and the time it takes to receive the packet. TRACEPATH - is similar to traceroute or tracert in that it displays the path taken by a pac...

Physical Layer (Layer 1) - This layer is responsible for the physical connections of the devices in the network. This layer is implemented through the use of devices such as hubs, repeaters, modem devices, and physical cabling. Data Link Layer (Layer 2) - This layer is responsible for the error-free delivery of data to the receiving device or node. This layer is implemented through the use of devices such as switches and bridge devices, as well as anything with a network interface, like...

Network A chain of communication that connects places. NOT THE INTERNET. Your home is its own ____ Hub Dumb, doesn't think, sits at physical layer of OSI model, Connects router to the network, sends data packets to ALL connected devices. Switch Used to connect devices in a specific networks, Builds a MAC address tables and sends accordingly. Is a more complex version of a Hub. Forwards data packets. Sits at Data Link Layer of the OSI model. Router is a point of connection bet...
