I have a Cisco 3750 24 port, a 3550 48 port and 2 new 48 port 2960-S switches. &nbsp;I need to cleanup and disco some of my old ones and want to create the fastest network possible utilizing gigabit framework. &nbsp;Which one do you recommend I use a the core switch and how do you suggest connecting servers, NAS, Backups and client machines to them and to the other switches? &nbsp;I have roughly 120 total end user devices and roughly 18 servers Thanks!

Cisco Core switch

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.
