Abstract :

Current trends in computing technologies are drifting towards distributed and parallel computing. These topologies emphasize on concurrent access schemes. Because of distributed computing, the use of shared resources like databases, memory, etc. is growing. Locking mechanisms can be used effectively to achieve high concurrency levels without corrupting the resources. There are a wide range of synchronization protocols, some providing strong consistency while others granting weak consistency. There is a trade-off between complexi ....etc

Chat protocols are very popular on the Internet. They have actually been very popular since the very first chat protocols appeared on the net. The Internet Relay Chat (IRC) was one of the first chat protocols, and quicklygained the status of being the most popular chat on the net. Today, IRC has several competitors from various other so called Instant Messaging (IM) protocols, such as ICQ. However, all of these different chat protocols havesomething in common; they are all insecure. The security is important feature in applications and protoco ....etc

In the era of the Internet, massive amounts of information and multimedia have become easily accessible in every corner of the world. The decreasing cost of storing data, and the increasing storage capacities of ever smaller devices, have been key enablers of this revolution. Current storage needs are being met because improvements in conventional technologies - such as magnetic hard-disk drives, optical disks and semiconductor memories - have been able to keep pace with the demand for greater and faster storage.

However, there is strong e ....etc

Hyper-Threading (HT) Technology is a groundbreaking innovation from Intel that improves PC responsiveness, produces performance gains of up to 25 percent.
Hyper-Threading Technology makes a single physical processor appear as two logical processors; the physical execution resources are shared and the architecture state is duplicated for the two logical processors. From a software perspective, this means operating systems and user programs can schedule processes or threads to logical processors as they would on multiple physical processors. ....etc

The Ping of Death uses a ping system utility to create an IP packet that exceeds the maximum 65,536 bytes of data allowed by the IP specification. The oversize packet is then sent to an unsuspecting system. Systems may crash, hang, or reboot when they receive such a maliciously crafted packet. This attack is not new, and all OS vendors have fixes in place to handle the oversize packets.

The AP is an artificial intelligence“based companion that will be
resident in software and chips embedded in the automobile dashboard. The heart of the
system is a conversation planner that holds a profile of you, including details of your
interests and profession.

A microphone picks up your answer and breaks it down into separate words with
speech-recognition software. A camera built into the dashboard also tracks your lip
movements to improve the accuracy of the speech recognition. A voice analyzer then
looks ....etc

Abstract
Silicon microprocessors have been the heart of computing world for more than forty years. Computer chip manufacturers are furiously racing to make the next microprocessor that will topple speed records. Sooner or later the physical speed and miniaturization limit of silicon microprocessors is bound to hit a wall.
Chipmakers need a new material to produce faster computing speed with fewer complexities. Itâ„¢s unbelievable where scientists have found this new material. DNA, the material our genes are made ....etc

Abstract
As Internet access becomes a basic necessity, alternative ways to go on-line without a computer will be required by mobile professionals, the visually impaired, and people without access to computers. Voice/speech based interface options will become an important part of the overall solution to access the Internet content. As the need for an alternative access method to the Internet has become evident, progress continues to be made by technologists to provide such solutions.
One key area of focus has been voice-base ....etc
