Backbone Definition
Just like the human backbone carries signals to many smaller nerves in the body, a network backbone carries data to smaller lines of transmission. A local backbone refers to the main network lines that connect several local area networks (LANs) together. The result is a wide area network (WAN) linked by a backbone connection.
The Internet, which is the ultimate wide area network, relies on a backbone to carry data over long distances. The Internet backbone consists of...

Network Definition
Network Definition
Network Definition: A network consists of multiple devices that communicate with one another. It can be as small as two computers or as large as billions of devices. While a traditional network is comprised of desktop computers, modern networks may include laptops, tablets, smartphones, televisions, gaming consoles, smart appliances, and other electronics.
Many types of networks exist, but they fall under two primary categories: LANs and WANs.
LAN (Local Area Network)...

LAN adapter
LAN adapter
A LAN adapter is an expansion board that is used to connect a computer or computing device to a network. LAN adapter is the most common and generic alternate name for a Network Interface Card (NIC). Similar products, such as a Wireless USB LAN Adapter or a Wii LAN Adapter are referred to as LAN adapters.

Local Area Network (LAN)
Local Area Network (LAN)
A local-area network (LAN) is a computer network that spans a relatively small area. Most often, a LAN is confined to a single room, building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves.
A system of LANs connected in this way is called a wide-area network (WAN). The difference between a LAN and WAN is that the wide-area network spans a relatively large geographical area. Typically, a...

Storage Networking
Storage Networking
Storage networking is the practice of linking together storage devices and connecting them to other IT networks. Storage networks provide a centralized repository for digital data that can be accessed by many users, and they use high-speed connections to provide fast performance. It's most common to find storage networks in enterprise settings, although some vendors do sell networked storage products for consumers and small businesses.

Ingress Filtering
Ingress Filtering
Ingress filtering is a method used by enterprises and internet service providers (ISPs) to prevent suspicious traffic from entering a network. When configured on an edge device such as a router or firewall, ingress filtering examines all inbound packets and then permits or denies entry to the network based on information in the packet header. It is a form of packet filtering.
Ingress traffic filtering is one of the first lines of defense in a network security strategy. It i...

Converged Network Adapter CNA
Converged Network Adapter CNA
Converged Network Adapter CNA: A converged network adapter (CNA) is a single network interface card (NIC) that contains both a Fibre Channel (FC) host bus adapter (HBA) and a TCP/IP Ethernet NIC. It connects servers to FC-based storage area networks (SANs) and Ethernet-based local area networks (LANs).
The CNA connects to the server via a PCI Express (PCIe) interface. The server sends both FC SAN and LAN and traffic to an Ethernet port on a converged switch ...
