Cache algorithms

memory called cache and multiple I/O parts and use sophisticated algorithm to meet the requirements of performance sensitive applications. Business critical application required high level of performance, availability, security and scalability, and therefore this will be most suitable for business applications to work with. - Front…

Web analytics is the multidisciplinary practice that aims to measure, collect and analyze web data to understand and optimize web usage.[1] Web analytics is a process, which helps to collect data related to each visit on the website to make metric driven decisions to improve the effectiveness of the website and help to take business justified decisions. It helps to retain existing visitors, to attract new visitors and to increase traffic. Web allow access to enormous amount of consumer…

The gradual transformation in data quantity has resulted in emergence of the Big data and immense datasets that need to be stored. Traditional relational databases are facing many difficulties meeting the requirements of the volume and heterogeneity structure of big data. NoSQL databases are designed with a novel data management system that can handle and process huge volumes of data. NOSQL systems provide horizontal scalability by supporting horizontal data partitioning across heterogeneous…

Each zone is constructed as virtual hierarchical that are geographic -specific. Each zone has a pre-defined number of nodes and a coordinator 〖C(i)〗_11^1to these nodes. The coordinator is assigned based on the proposed IHRW hashing algorithm, as illustrated in heuristic 3. Heuristic 3: The adaptive HRW protocol proposed in figure 5 is implemented in each level of the virtual hierarchical. Suppose the system contains n_od nodes that will be divided into number of Rendezvous geographic Zones…

wild three-headed dog that controlled the passageway to the underworld (Hades). Kerberos shielded that only the deceased, not living humans, pass into Hades. In our world, Kerberos is a system that handle powerful data encryption algorithms ahead with message digest algorithms to guarantee data confidentiality and integrity in the time of the authentication process. Confidentiality assures that only parties with a shared key could encrypt or decrypt the data where as Integrity assures that the…

Passwords have been used for the purpose of authentication since Roman Periods. Password-based systems, Validation based on something what the user knows about their identity are generally more common and necessary to access the available resources in World Wide Web through networks and the internet (Vaithyasubramanian & Christy, 2015). Cracking user passwords online is one of the essential skills in hacking and penetration testing with the aim is to illegitimately access the system through an…

While ubiquitous Internet access is extremely convenient and enables marvelous new applications for mobile users, it also creates a major security vulnerability—by placing a passive receiver in the vicinity of the wireless transmitter, that receiver can obtain a copy of every packet that is transmitted! These packets can contain all kinds of sensitive information, including passwords, social security numbers, trade secrets, and private personal messages. A passive receiver that records a copy of…

power source and install a mining system for mining resources and to install a life support infrastructure (“Mars”). The second mission for Mars colonization is predicted to occur in 2024 and will hold both cargo and crew. This mission is to build a cache in space for distributing fuel and to prepare for future missions (“Mars”). If SpaceX completes these missions in the projected time frame, they will be able to send colonists to Mars a decade before NASA can achieve such a task…
