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. T...

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...

HISTORY OF BIOMETRICS

By
1.                                         HISTORY OF BIOMETRICS Idea of biometric was introduced hundreds, even thousands of years ago.In an cave estimated to be at least 31,000 years old,-painting representing the use of signature is found. In early as 500 B.C. – business transactions are recorded in clay tablets that include fingerprints.”Chinese parents also used fingerprints and footprints to differentiate children from one another. But true biometric systems began with the emergence of computer systems.  •        1858       – First systematic capture of hand images for identification •        1870       – develops anthropometries to identify individuals •        1892       – deve...

INTRODUCTION TO BIOMETRICS

By
            INTRODUCTION TO BIOMETRICS The term “biometrics” is derived from the Greek words bio (life) and metric (to measure).Biometrics are automated methods of identifying a person or verifying the identity of a person based on a physiological or behavioral characteristic. Biometric-based authentication is the automatic identity verification, based on individual physiological or behavioral characteristics, such as fingerprints, voice, face and iris. Since biometrics is extremely difficult to forge and cannot be forgotten or stolen, Biometric authentication offers a convenient, accurate, irreplaceable and high secure alternative for an individual, which makes it has advantages over traditional cryptography-based authentication schemes. It has become a hot interdisciplinary topic involving biometric and Cryptography. Biometric data is personal privacy information, which uniquely and permanently associated with a person and cannot be replaced lik...

A tiny glass disc can store 360TB of data for 13.8 billion years

By
It's estimated that humans are producing the equivalent of 10 million Blu-ray discs' worth of data  every single day  - and all of those ones and zeroes have to be stored somewhere. Now researchers in the UK just might have the solution: a five-dimensional (5D) digital data disc that can store 360 terabytes of data for some 13.8 billion years. To create the data disc, researchers from the University of Southampton  used a process called femtosecond laser writing, which  creates small discs of glass using an ultrafast laser that generates short and intense pulses of light. These pulses can write data in three layers of nanostructured dots separated by 5 micrometres (that's 0.005 mm). So where do the five dimensions come from? First there's the three-dimensional position of each dot within the layers, and then the extra dimensions are the size and orientation of the dot. The nanostructures created by the technology can be read using an optical microscope in tan...

Facebook will now offer to hide your ex from you after a breakup

By
  Share on Facebook   (26k)   Tweet     Share     Pin   The more ubiquitous Facebook becomes  around the world, the more likely you are to one day have an  ex-boyfriend, -girlfriend, or -spouse using the service . So what happens when you break up, and you continue to see the trail of their life without you all over the News Feed? Until now, you've had to hide that person, unfriend them, or block them outright. But that won't sever the connection altogether — you may be still tagged in your ex's old photos, for example, or see their name pop up as a suggestion when you write a message. That starts to change today  with new tools  that will pop up when you go to change your relationship status. The tools have three major components: limiting how much of your ex you see on Facebook; limiting how much your ex sees of you on Facebook; and limiting people's ability to see past posts where the two of you are together.
