Computer and Network Hardware - Assignment Example Protocols like POP3, IMAP, LDAP and HTTP services use DNS to avoid IP conflicts on the networks. Hardware (Physical) address is the unique hexadecimal serial number assigned to each Ethernet network device. The address is permanently set at the time of manufacture and cannot be changed. It is unique to help distinguish among devices. The hardware addresses are exactly 6 bytes in length, and are usually written in hexadecimal as 12:34:56:78:90:AB. The first six digits identify manufacturer while the last six is the serial number of the card. Each manufacturer of Ethernet devices applies for a certain range of hardware addresses they can use. DHCP failover occurs when using DHCP redundancy. With two DHCP servers serving different scopes, for example .100-.150 on one and .200-.250 on the other, challenges pursue. In the case one server fails, all clients that received a lease from that server, will have to get a new IP from the other server. That basically means all network connections on the client will be lost and causing a danger unlike no redundancy. DHCP availability is crucial. The existing of network is dependent on the DHCP availability, since it is the basic point of assigning TCP/IP configuration. If it fails or breaks down the network communication is lost. That indicates that DHCP has to be available throughout. Subnetting addresses hardware performance issues. Using subnetting reduces CPU overload. The servers will have increased processing power and available. The network hardware like routers and other devices that handle data traffic are also optimized. The bandwidth is available to network devices for their effective performance. To communicate, computers on LAN are interconnected using a switch. The switch is then connected to a router that links LAN to an external network, internet. To access internet through a single computer, you can either configure one PC as an ICS (Internet Connection Sharing) or
