what is the role of a dhcp server
Dynamic Host Configuration Protocol The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on TCP/IP networks whereby a DHCP server dynamically assigns an IP address and other network configuration parameters to each device on a network so they can communicate with other IP networks.[1] A DHCP server enables computers to request IP addresses and networking parameters automatically from the Internet service provider (ISP), reducing the need for a network administrator or a user to manually assign IP addresses to all network devices.[1] In the absence of a DHCP server, a computer or other device on the network needs to be manually assigned an IP address, or to assign itself an APIPA address, which will not enable it from communicating outside its local subnet.
Dehydroepiandrosterone Dehydroepiandrosterone (DHEA), also known as androstenolone, is an endogenous steroid hormone.[2][5] It is one of the most abundant circulating steroids in humans,[6] in whom it is produced in the adrenal glands,[7] the gonads, and the brain,[8] where it functions as a metabolic intermediate in the biosynthesis of the androgen and estrogen sex steroids.[5][9] However, DHEA also has a variety of potential biological effects in its own right, binding to an array of nuclear and cell surface receptors,[10] and acting as a neurosteroid and neurotrophin.[11]
