CISC VS RISC computers (all details)

By
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. The CISC approach attempts to minimize the number of instructions per program, sacrificing

DHCP principle , DHCP server and client communication process

By
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

Recommendation System literature review | Building a recommendation system

By
People have always relied on the recommendations from their peers or the advice of experts to support their decision making. Amazon.com has been using collaborative filtering for a decade to recommend products to their customers, and Netflix valued improvements to the recommender technology underlying their movie rental service at $1M via the widely published Netflix Prize [6]. Research on recommender algorithms garnered significant attention in 2006 when Netflix launched the Netflix Prize to improve the state of movie recommendation. The objective of this competition was to build a recommender algorithm that could beat their internal CineMatch algorithm in offline tests by 10%. It sparked a flurry of activity, both in academia and amongst hobbyists. The $1 M prize demonstrates the value that vendors place on accurate recommendations [8]. Recommender Systems provide the users with the suggestions of information that may be useful to the users to make their decisions on various sit

Creepiest picture with background stories 5) Aminityville story In 1976, when they captured this family photo together at their home 112 Ocean Avenue, Amityville, they had no idea that this would become one of America’s most talked about horror stories. Above is the DeFeo children (back row, left to right): John, Allison, Marc. (Front row): Dawn, Ronald “Butch” Jr. Their parents Ronald and Louise are not pictured – the only surviving member of the family now is Butch. At around 6.30pm, Butch burst into a local bar screaming, “You got to help me! I think my mother and father are shot!” When the police arrived at the family home, every member of the family had been shot in their sleep, execution style. After hours of police interrogation, it was discovered that Butch had shot all his loved ones in cold blood, he told the police, “Once I started, I just couldn’t stop. It went so fast.” The case since became known as “The Amityville Horror Story.” 4) Coopers´ family photo Back in the 1950´s, the Cooper family from Texas moved into their new house. Once there, they took a family photo but when the picture was developed, the image of a body falling from the ceiling was clearly visible. As further investigation on this story has brought no plausible explanation, there exist many speculations; including one that argues that the shadow is the ghost of the previous owner of the house. 3) It Sees You While You’re Sleeping …And Takes Selfies. A mother comes home exhausted from work and lends her little boy her phone to play with probably so she could have a one on one intimate encounter with a glass of wine with no interruptions. When it was time to go to bed, she found her son asleep in her bedroom with her cell phone beside him. She picked up the phone to make sure he didn’t mess up any of her apps and discovered that her son had take a few selfies of himself before he fell fast asleep and then ….someone or something else took one more selfie as the little boy slept. The woman states that she is a single mother and that no one else was in the house besides herself and her little boy. 2) A photo boy A photograph taken of an investigation into the Amityville house. Investigator swore that there was no child in the frame when the picture was taken, as the entire premises had been closed off. 1) Locked for 25 years This is the picture of a French woman, Blanche Monnier, when she was around 50. A whole 25 years after she was last seen, and presumed dead or missing by all. Her mother and brother even held a mourning for her. Poor souls, you must think! But no, they were hiding a terrible secret. After discovering that Blanche was in love with a lawyer, someone from a lower social strata than her family. As a punishment for this 'crime', her own mother locked her up in the attic for 25 years.
