Switch (Switch) imatanthauza "switch" ndipo ndi chipangizo cha netiweki chomwe chimagwiritsidwa ntchito potumiza chizindikiro chamagetsi (chowunikira). Chingapereke njira yapadera yamagetsi ya ma node awiri a netiweki ya switch yolowera. Ma switch odziwika kwambiri ndi ma switch a Ethernet. Ena odziwika bwino ndi ma switch a mawu a pafoni, ma switch a fiber ndi zina zotero.
Ntchito zazikulu za switch ndi monga physical addressing, network topology, error checking, frame sequence, ndi flow control. switch iyi ilinso ndi ntchito zatsopano, monga kuthandizira VLAN (Virtual Local Area Network), kuthandizira link aggregation, ndipo zina zimakhala ndi firewall.
1. Monga ma hubs, ma switch amapereka madoko ambiri olumikizira ma waya, zomwe zimathandiza kuti ma waya azilumikizidwa mu topology ya nyenyezi.
2. Monga zobwerezabwereza, ma hub, ndi milatho, switch imapanganso chizindikiro chamagetsi chosasinthika pamene ikupititsa patsogolo mafelemu.
3. Monga milatho, ma switch amagwiritsa ntchito njira yofanana yotumizira kapena kusefa pa doko lililonse.
4. Monga mlatho, switch imagawa netiweki ya dera lanu m'magawo angapo ogundana, omwe aliwonse ali ndi bandwidth yodziyimira payokha, motero imakweza kwambiri bandwidth ya netiweki ya dera lanu.
5. Kuwonjezera pa ntchito za milatho, ma hub, ndi ma repeater, ma switch amapereka zinthu zapamwamba kwambiri monga ma virtual local area network (VLANs) ndi magwiridwe antchito apamwamba.
