An algorithm is a representation of a solution to a problem. If a problem can be defined as a difference between a desired situation and the current situation in which one is, then a problem solution is a procedure, or method, for transforming the current situation to the desired one. We solve many such trivial problems every day without even thinking about it, for example making breakfast, travelling to the workplace etc. But the solution to such problems requires little intellectual effort and is relatively unimportant. However, the solution of a more interesting problem of more importance usually involves stating the problem in an understandable form and communicating the solution to others. In the case where a computer is part of the means of solving the problem, a procedure, explicitly stating the steps leading to the solution, must be transmitted to the computer. This concept of problem solution and communication makes the study of algorithms important to computer science.

Data Structures are the programmatic way of storing data so that data can be used efficiently. Almost every enterprise application uses various types of data structures in one or the other way.

Exchange of information through the use of speech, signs or symbols is called communication. When early humans started speaking, some 5,00,000 years ago, that was the first mode of communication. Before we dive into modern technologies that drive communication in contemporary world, we need to know how humans developed better communication techniques to share knowledge with each other.

HTML5 canvas provides methods which allow modifications directly to the transformation matrix. The transformation matrix must initially be the identity transform. It may then be adjusted using the transformation methods.

Data communication in a computer network refers to the process of transferring digital data between two or more devices connected within a network, allowing them to exchange information through a transmission medium like wires or wireless signals, essentially enabling communication between different computer systems by sending and receiving data packets across a network

What entails of psychology. How you can use psychology to understand human behaviour and the human perspectives.

Hardwired systems are inflexible. General purpose hardware can do different tasks, given correct control signals. Instead of re-wiring, supply a new set of control signals

Together with an explosive growth of the mobile applications and emerging of cloud computing concept, mobile cloud computing (MCC) has been introduced to be a potential technology for mobile services. MCC integrates the cloud computing into the mobile environment and overcomes obstacles related to the performance (e.g., battery life, storage, and bandwidth), environment (e.g., heterogeneity, scalability, and availability), and security (e.g., reliability and privacy) discussed in mobile computing. This paper gives a survey of MCC, which helps general readers have an overview of the .MCC including the definition, architecture, and applications. The issues, existing solutions, and approaches are presented. In addition, the future research directions of MCC are discussed. Copyright © 2011 John Wiley & Sons, Ltd

Data backups and cloud computing can be treated as two separate subjects in one context and can be considered as complementary in another context. Data backups have been common since the inception of computers. Cloud computing, on the other hand, is a relatively recent phenomenon. The cloud infrastructure helps with effective data backups and is a low-cost disaster recovery option. Data backups help in ensuring restoration of data in case of data loss, data corruption, and data integrity issues.

Cloud computing is a means by which computational power, storage, collaboration infrastructure, business processes and applications can be delivered as a utility, that is, a service or collection of services that meet your demands. The aspect of pay-as-you-go in the cloud is referred to as elasticity and is an extremely important concept within cloud computing. On the whole, the cloud is basically an umbrella term that covers on-demand access to various computing resources. XaaS (Anything-as-a-Service) - This is a generic term which refers to any service which is available as cloud enabled service through internet. Some time it is also called ‘everything-as-a-service Backend-as-a-Service (BaaS) – Backend as a service (BaaS), or mobile backend as a service (mBaaS) is a model of cloud computing in which the vendor provides web and mobile application developers with tools and services to create a cloud backend for their applications. BaaS vendors typically use custom SDKs and APIs to give developers the ability to connect their applications to backend cloud storage and features such as user management, push notifications, and social network integration. Cloud Foundry – Cloud Foundry is an open-source cloud platform as a service that was originally developed as a joint venture between VMware, EMC, and General Electric, and is now owned by Pivotal Software. Cloud Management Platform (CMP) – A cloud management platform (CMP) is a product that gives the user integrated management of public, private, and hybrid cloud environments. Cloud Marketplace - A cloud marketplace is an online marketplace, operated by a cloud service provider (CSP), where customers can browse and subscribe to software applications and developer services that are built on, integrate with, or supplement the CSP’s main offering. Amazon’s AWS . Marketplace and Microsoft’s Azure store are examples of cloud marketplaces. Cloud Washing – Cloud washing is a deceptive marketing technique used to rebrand old products by connecting them to the cloud, or at least to the term cloud. Grid computing is a group of networked computers that work together as a virtual supercomputer to perform large tasks, such as analyzing huge sets of data or weather modeling. Through the cloud, you can assemble and use vast computer grids for specific time periods and purposes, paying, if necessary, only for what you use to save both the time and expense of purchasing and deploying the necessary resources yourself. Also by splitting tasks over multiple mac
