The difficulty of managing front and rear in an array-based non-circular queue can be overcome if we treat the queue position with index 0 as if it comes after the last position (in our case, index 9), i.e., we treat the queue as circular. Note that we use the same array declaration of the queue. Empty queue: Non-empty queues: Implementation of operations on a circular queue: Testing a circular queue for overflow There are two conditions: (front=0) and (rear=capacity-1) front=rear+1 If any of these two conditions is satisfied, it means Read More

In the most basic of descriptions, quantum cryptography is any set of cryptographic tasks that are done by quantum systems. The most famous of these systems is known as quantum key distribution (QKD). By using quantum mechanics, the crytograph can ensure a secure communication. Because of the randomness, it allows for the two parties to generate a bit string that they – being the ones that know it – can then use to encrypt or decrypt messages. Because quantum cryptography is dealing with quantum, the two parties that are using Read More

The problem with the technology age is that there are so many different remote controls to go with each piece of hardware we purchase. Programming the Philips universal remote requires that you have the codes of all the different pieces of hardware to configure with the remote. Once you've configured, you'll be able to use the remote on all the equipment in your entertainment center–sound, television, DVD player–and can shelve the excess remotes. The first step is to collect all of the paperwork for your different remotes. For example, if Read More

A decompiler is a program which takes executable code and produces source code from it. A compiler creates executable code from source code; A decompiler attempts to reverse this process. A decompiler is a specialized version of a disassembler. While a disassembler converts executable code to assembly language, a decompiler attempts to go further and convert the executable code to source code in a higher level language, such as C or C++. Decompilers Boomerang The goal is the Boomerang project is an attempt to develop a real decompiler for machine Read More

The Global Catalog (GC) is an important component in Active Directory because it serves as the central information store of the Active Directory objects located in domains and forests. Because the GC maintains a list of the Active Directory objects in domains and forests without actually including all information on the objects and it is used when users search for Active Directory objects or for specific attributes of an object, the GC improves network performance and provides maximum accessibility to Active Directory objects. The Global Catalog server is the domain Read More

Searching is the process of finding the location of a given element in a set of elements. The search is said to be successful if the given element is found i.e., the element does exist in the collection (such as an array); otherwise it is unsuccessful. Two simple approaches to searching are: Linear search: This method traverses a list sequentially to locate the search key. Binary search: This method works on sorted lists by progressively making better guesses to find the location of a search key.
