1. Explain with principle: the DHCP server and client communication process DHCP stands for Dynamic Host Configuration Protocol. It handles the automatic assignment of IP addresses and other configuration settings for devices on your network. DHCP automates Network and Sharing Center in your control panel. This is especially good for people who have laptops, aren't hooked up to the Internet all the time and often move from place to place with their portable devices. They can simply get a new IP address as needed without having to do it manually. DHCP is designed to make the assignment of IP addresses and other network configuration information faster and easier. DHCP is a protocol that uses Level 4 on the OSI model. It communicates using User Datagram Protocol (UDP) datagrams through UDP Port 68. DHCP works with most current and past Windows clients, and also Linux, Macintosh, and many network-capable printers. DHCP is desi...

Black cats have an unfair reputation of being bad luck. A black cat crossed road and just a second later a big accident was happened. Personally i love cat very much and i have a cat in my house. This may be an co-incident. Here is an story also : Black Cats - lucky or unlucky? Black cats weren’t always considered unlucky. In Ancient Egypt, from about 3100BC to 390AD, all cats, including black cats, were considered sacred and worshipped. The goddess Bastet (or Bast - see image right) was originally depicted as a lioness, fiercely protective and warlike, however her image softened over time and became more strongly associated with domestic cats. She personified the playfulness, grace, affection and cunning of a cat while still being strong powerful like larger felines. Cat worship declined in Egypt following the banning of the cult of Bast in 390 AD. They are still kept as pets and used as pest control. Cats continue to be revered to some extent in Muslim tradition. Cats have...

CISC Introduction            The term "CISC" (complex instruction set computer or computing) refers to computers designed with a full set of computer instructions that were intended to provide needed capabilities in the most efficient way. Intel's   Pentium   microprocessors are CISC microprocessors. CISC is a   processor design   where single   instructions   can execute several low-level operations (such as a load from   memory , an arithmetic   operation , and a   memory store ) or are capable of multi-step operations or   addressing modes   within single instructions. The primary goal of CISC architecture is to complete a task in as few lines of assembly as possible. This is achieved by building processor hardware that is capable of understanding & executing a series of operations, this is where our CISC architecture introduced. T...

              Auxiliary storage, secondary storage, or external storage are devices that store noncritical system data like documents, multimedia and programs, which are used whenever they are required. These files are invoked from the auxiliary storage when needed and then transferred to the primary storage so that the CPU can process them. The results of the process can also be sent back to the auxiliary storage for later retrieval. These storage devices hold data and programs for future use and are considered nonvolatile storage that retains information even when power is not available. The best example of auxiliary storage is hard disk drives and optical storage media like CDs, DVDs, and Blue ray. Other auxiliary storage belongs to the peripheral devices category as well, such as flash drives and any type of memory card. ž   Auxiliary storage devices can be categorized in two types based on data access.  1. Sequential Access ...
