Original networking protocol for DOS and Windows PCs: - Port Address Translation (PAT) - NetFlow - NetBIOS - Switching - Hosts - ️️NetBIOS The original networking protocol for DOS and Windows PCs. These packets did not contain a network address and were not easily routable between networks. As a result, the interface to NetBIOS and the transport part of NetBIOS were later separated so that NetBIOS applications could use routable protocols such as TCP/IP and SPX/IPX (PC Magazine, 2018). Developed by Cisco for collection/monitoring of network traffic flow data generated by NetFlow-enabled routers/switches: - Port Address Translation (PAT) - NetFlow - NetBIOS - Switching - Hosts - ️️NetFlow A network protocol developed by Cisco for the collection and monitoring of network traffic flow data generated by NetFlow-enabled routers and switches (Rouse, 2014) Most common way network address translation is implemented. Also called "NAT overloading," or "network address port translation" (NAPT): - Port Address Translation (PAT) - NetFlow - NetBIOS - Switching - Hosts - ️️Port Address Translation (PAT) The most common way network address translation is implemented. Also called "NAT overloading," "network address port translation" (NAPT) and "NAT/PAT." It assigns a different TCP port number to each client session with a server on the internet. When responses come back from that server, the source port numberbecomes the destination port number and determines which user to route the packets to. It also validates that the incoming packets were indeed requested (PC Magazine, 2018). Automatic assigning of IP addresses to client machines logging into a network: - Border Gateway Protocol (BGP) - Open Systems Interconnection Model (OSI Model) - Dynamic Host Configuration Protocol (DHCP) - Classless Interdomain Routing (CIDR) - Domain Name System (DNS) - ️️Dynamic Host Configuration Protocol (DHCP) The automatic assigning of IP addresses to client machines logging into an IP network. The same address, although technically temporary, may remain with a machine indefinitely unless a conflict arises with other devices on the network. The software, which resides in the router or a server, eliminates the need to manually assign permanent "static" IP addresses to devices. In a home network, it is typically in the wireless router (PC Magazine, 2018). Internet's system for converting alphabetic names into numeric IP addresses: - Border Gateway Protocol (BGP) - Open Systems Interconnection Model (OSI Model) - Dynamic Host Configuration Protocol (DHCP) - Classless Interdomain Routing (CIDR) - Domain Name System (DNS) - ️️Domain Name System (DNS) The internet's system for converting alphabetic names into numeric IP addresses. For example, when a web address (URL) is typed into a browser, these servers return the IP address of the web server associated with that name. In this made-up example, it converts the URL "" into the IP address 204.0.8.51. Without this, you would have to type the series of four numbers and dots into your browser to retrieve the website, which you actually can do (PC Magazine, 2018). Connected via cable: - Optical - Gateway - Wireless - Wired - Port Forwarding - ️️Wired Connected via cable (PC Magazine, 2018)Communications between computers, telephones, and other electronic devices using light: - Optical - Gateway - Wireless - Wired - Port Forwarding - ️️Optical Communications between computers, telephones, and other electronic devices using light. This type of network is far more reliable and has far greater potential transmission capacity than networking in the electrical domain (PC Magazine, 2018).
