Abort
To terminate a process before completion. Generally used in reference to a mainframe program, especially one that has gone awry.
In the world of PC (Personal Computer) we are more inclined to exit a program or command with the 'Escape key' on Keyboard.

'access' used for verity of method. In general, word 'access' stand for 'call up' or 'activate' for use. A computer might contain a lot of program or files contain data. But until you call it. The process of call any program or file with respective computer program called as 'access' the program or file.

Genetics
Genetics
Genetics from Ancient genetikos, “genitive” and that fenesis, “origin”, a discipline of biology, is the science of heredity and variation in living organisms. The fact that living things inherit traits from their parents has been used since prehistoric times to improve crop plants and animals through selective breeding. However, the modern science of genetics, which seeks to understand the process of inheritance, only began with the work of Gregor Mendel in the midnineteenth century. Although he did not know the physical basis for heredity, Mendel observed that organisms inherit traits in a discrete manner—these basic units of inheritance are now called genes.DNA, the molecular basis for inheritance. Each strand of DNA is a chain of nucleotides, matching each other in the center to form what look like rungs on a twisted ladder.DNA, the molecular basis for inheritance. Each strand of DNA is a chain of nucleotides, matching each other in the center to form what look like rungs on a twisted ladder.enes correspond to regions within DNA, a molecule composed of a chain of four different types of nucleotides—the sequence of these nucleotides is the genetic information organisms inherit. DNA naturally occurs in a double stranded form, with nucleotides on each strand complementary to each other. Each strand can act as a template for creating a new partner strand—this is the physical method for making copies of genes that can be inherited.The sequence of nucleotides in a gene is translated by cells to produce a chain of amino acids, creating proteins—the order of amino acids in a protein corresponds to the order of nucleotides in the gene. This is known as the genetic code. The amino acids in a protein determine how it folds into a threedimensional shape this structure is, in turn, responsible for the proteins function. Proteins carry out almost all the functions needed for cells to live. A change to the DNA in a gene can change a proteins amino acids, changing its shape and function this can have a dramatic effect in the cell and on the organism as a whole.Although genetics plays a large role in the appearance and behavior of organisms, it is the combination of genetics with what an organism experiences that determines the ultimate outcome. For example, while genes play a role in determining a persons height, the nutrition and health that person experiences in childhood also have a large effect.

P3P
P3P
P3P is a machine readable privacy policies for a web site. It is a W3C standard on how to specify privacy policies for a web site. The standard has both a human readable part to it, as well as a machine readable part. The standard can be found here with errata and other information about it at P3P here.
Currently IE6 will be supporting a feature that reads the machine readable p3p policy of a web site. Depending on the settings in the options dialog, it may disable certain features of the browser, such as the capability of setting cookies, unless there is a p3p file in place, and the file matches the user's preferences. So unless you implement a p3p policy on your web site, some users may have a bad experience visiting your site.

DDoS
DDoS DDoS - (Distributed Denial-of-Service attack)is one kind of DoS which is: an attempt to make a computer resource unavailable to its intended users. Although the means to, motives for, and targets of a DoS attack may vary, it generally consists of the concerted, malevolent efforts of a person or persons to prevent an Internet site or service from functioning efficiently or at all, temporarily or indefinitely.
Main Difference Between DoS and DDoS is, DoS Attack is only performed from a Single Source, where DDoS is Distributed Denial-of-Service Attack, where Target is Single, attack Come from A group of Source which can be in Distributed area even Different Distributed Country World Wide!

QoS
QoS is a general term that incorporates bandwidth, latency, and jitter to describe a network's ability to customize the treatment of specific classes of data. For example, QoS can be used to prioritize video transmissions over Web-browsing traffic. Advanced networks can offer greater control over how data traffic is classified into classes and greater flexibility as to how the treatment of that traffic is differentiated from other traffic.
MPLS
MPLS, Normally Mean "Multiprotocol Label Switching". MPLS is a standards-approved technology for speeding up network traffic flow and making it easier to manage. MPLS involves setting up a specific path for a given sequence of packets, identified by a label put in each packet, thus saving the time needed for a router to look up the address to the next node to forward the packet to. MPLS is called multiprotocol because it works with the Internet Protocol (IP), Asynchronous Transport Mode (ATM), and frame relay network protocols. With reference to the standard model for a network (the Open Systems Interconnection, or OSI model), MPLS allows most packets to be forwarded at the layer 2 (switching) level rather than at the layer 3 (routing) level. In addition to moving traffic faster overall, MPLS makes it easy to manage a network for quality of service (QoS). For these reasons, the technique is expected to be readily adopted as networks begin to carry more and different mixtures of traffic.
VLAN - Virtual LAN
The term VLAN was specified by IEEE 802.1Q; it defines a method of differentiating traffic on a LAN by tagging the Ethernet frames. By extension, VLAN is used to mean the traffic separated by Ethernet frame tagging or similar mechanisms.
LAN - Local Area Networks
LAN - Local Area Networks - A network of interconnected computers that is distinguished by its small geographical size (typically measured in meters), privately owned, High-speed (usually measured in megabits per second), and low error rate (typically 1 bit in a trillion).
3D
In computers, 3D (three dimensions or three dimensional) describes an image that provides the perception of depth. When 3-D images are made interactive so that users feel involved with the scene, the experience is called virtual reality. You usually need a special plug-in viewer for your Web browser to view and interact with 3D images. Virtual reality experiences may also require additional equipment.
3D image creation can be viewed as a three-phase process of: tessellation, geometry, and rendering. In the first phase, models are created of individual objects using linked points that are made into a number of individual polygons (tiles). In the next stage, the polygons are transformed in various ways and lighting effects are applied. In the third stage, the transformed images are rendered into objects with very fine detail.
Popular products for creating 3D effects include Extreme 3D, LightWave 3D, Ray Dream Studio, 3D Studio MAX, SoftImage 3D, and Visual Reality. The Virtual Reality Modelling Language (VRML) allows the creator to specify images and the rules for their display and interaction using textual language statements.

FastEthernet
Fast Ethernet is an upgraded standard in connecting computers into a local area Network (LAN). It works just like regular Ethernet except it can transfer data at a peak rate of 100 mbps. Also referred to as 100BaseT, fast Ethernet is more expensive and less common than its slower 10BaseT sibling.
Additionally Ethernet is the most widely installed local area network technology. Now specified in a standard, IEEE 802.3, Ethernet was originally developed by Xerox and then developed further by Xerox, DEC, and Intel. An Ethernet LAN typically uses coaxial cable or special grades of twisted pair wires.
Other Type of Ethernet is Gigabit Ethernet, Which provides an even higher level of backbone support at 1000 megabits per second (1 gigabit or 1 billion bits per second).

The most commonly installed Ethernet systems are called 10BASE-T and provide transmission speeds up to 10 Mbps. Devices are connected to the cable and compete for access using a Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol.
Additionally Fast Ethernet or 100BASE-T provides transmission speeds up to 100 megabits per second and is typically used for LAN backbone systems, supporting workstations with 10BASE-T cards.
