Examples include enterprise software, accounting software, office suites, graphics software and media players.
Mobile Computing is a technology that allows transmission of data, voice and video via a computer or any other wireless enabled device without having to be connected to a fixed physical link.
Cloud Computing is the use of hardware and software to deliver a service over a network (typically the Internet). With cloud computing, users can access files and use applications from any device that can access the Internet. An example of a Cloud Computing provider is Google's Gmail.
What new paradigms do you think may be significant in the future of interactive computing? A truly ubiquitous computing experience would require the spread of computational capabilities literally everywhere. Another way to achieve ubiquity is to carry all of your computational need with you everywhere, all the time.
What is High Performance Computing? High Performance Computing most generally refers to the practice of aggregating computing power in a way that delivers much higher performance than one could get out of a typical desktop computer or workstation in order to solve large problems in science, engineering, or business.
Engineers have taken a major step towards creating computers that work at the speed of light. They say the next generation of computers and mobile devices will be capable of speeds millions of times faster than current machines.
This set of Computer Fundamentals Multiple Choice Questions & Answers (MCQs) focuses on “Cloud Computing”. Cloud providers provide cloud services to the cloud users. Explanation: The statement is true. There are three types of users often called as cloud stakeholders.
Centralized computing is a type of computing architecture where all or most of the processing/computing is performed on a central server. The central server, in turn, is responsible for delivering application logic, processing and providing computing resources (both basic and complex) to the attached client machines.
Here, are important benefits for using Cloud computing in your organization:
- Cost Savings. Cost saving is the biggest benefit of cloud computing.
- Strategic edge.
- High Speed.
- Back-up and restore data.
- Automatic Software Integration.
- Reliability.
- Mobility.
- Unlimited storage capacity.
The six principles - detailed in the recently published ISACA publication Guiding Principles for Cloud Computing Adoption and Use - include enablement, cost/benefit, enterprise risk, capability, accountability and trust.
The name cloud computing was inspired by the cloud symbol that's often used to represent the Internet in flow charts and diagrams. Cloud computing is a general term for anything that involves delivering hosted service over the Internet. The cloud symbol was used to represent the Internet as early as 1994.
Joseph Carl Robnett Licklider
A cloud server is a virtual server (rather than a physical server) running in a cloud computing environment. It is built, hosted and delivered via a cloud computing platform via the internet, and can be accessed remotely. They are also known as virtual servers.
Access your data anywhere, anytime. An Internet
cloud infrastructure maximizes enterprise productivity and efficiency by ensuring your application is always accessible.
Disadvantages:
- No longer in control.
- May not get all the features.
- Doesn't mean you should do away with servers.
- No Redundancy.
- Bandwidth issues.
Following are the characteristics of Cloud Computing:
- Resources Pooling.
- On-Demand Self-Service.
- Easy Maintenance.
- Large Network Access.
- Availability.
- Automatic System.
- Economical.
- Security.
Cloud computing is the latest paradigm shift in information technology. Virtualization, which combines computing devices for greater responsiveness, boosts the value of cloud computing because fewer devices are needed. This new method for utilizing computing resources is quickly evolving business operations.
Simply put, cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale.
We use paradigms to help understand how we can approach a problem and find a solution. We think about things like functional, imperative, object-oriented, etc. There may be other parts that you realize that object-oriented would be better. In summary, some paradigms work better for certain types of problems.
The current trends in computer science are Machine Learning (ML), blockchain, Cyber Security, Internet of Things (IoT) and Big Data. The data being generated per day is so large (big) that it needs sophisticated techniques (like Hadoop and Spark) to properly store, process and retrieve it.
Distributed computing is a field of computer science that studies distributed systems. A distributed system is a system whose components are located on different networked computers, which communicate and coordinate their actions by passing messages to one another.
Types of Computing Environments
- Personal Computing Environment. In the personal computing environment, there is a single computer system.
- Time Sharing Computing Environment.
- Client Server Computing Environment.
- Distributed Computing Environment.
- Cloud Computing Environment.
- Cluster Computing Environment.
Different Types of Cloud Computing Service Models
- Infrastructure as a Service (IAAS)
- Platform as a Service (PAAS)
- Software as a Service (SAAS)
- Storage as a Service (SAAS)
- Communications as a Service (CAAS)
- Network as a Service (NAAS)
- Monitoring as a Service (MAAS)
- Conclusion :
There are three main cloud computing types, with additional ones evolving—software-as-a-service (SaaS) for web-based applications, infrastructure-as-a-service (IaaS) for Internet-based access to storage and computing power, and platform-as-a-service (PaaS) that gives developers the tools to build and host Web
INTRODUCTION. A computer is a programmable machine designed to perform arithmetic and logical operations automatically and sequentially on the input given by the user and gives the desired output after processing. Computer components are divided into two major categories namely hardware and software.
In computing, an input device is a peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system such as a computer or other information appliance. Examples of input devices include keyboards, mice, scanners, digital cameras and joysticks.
A computer or computer system is a set of tools that helps you perform information related task. You can categorize various tools as follows: software, application software, system software, hardware, input devices, output devices, CPU and RAM, storage devices, telecommunications devices, hardware connections.
