Computing and Its Types – Luke Lonergan

Computing and Its Types – Luke Lonergan

Computing is any goal oriented activity which requires benefits from or creating algorithmic processes such as through computers and it includes designing, developing and building hardware and software systems; processing, structuring and managing different types of information doing scientific research on and with computers making computer systems behave intelligently as well as creating and using communications and entertainment media. The field of computing includes computer engineering and software engineering, computer science, information systems and information technology.

Computer engineering is a discipline which integrates several fields of electrical engineering and computer science required to develop computer hardware and software and computer engineers usually have training in electronic engineering or electrical engineering, designing software as well as hardware software integration instead of only software engineering or electronic engineering.

Software engineering is an application of a systematic, disciplined, quantifiable approach to the design, development, operation and maintaining software and the study of these approaches that is the application of engineering to software.

Computer science and computing science is the scientific and practical approach to computation and its applications and a computer scientist specializes in the theory of computation and the design of computational systems.

Information systems is a concept of complementary networks of hardware as well as software that people and organizations use to collect, filter, process, create as well as distribute data and a majority of information systems programs are located in business schools and they can have different names such as management information systems, computer information systems or business information systems.

Information technology is the application of computers and telecommunications equipment to store, retrieve, transmit as well as manipulate data often in the context of a business and other enterprise and the term is commonly used as a synonym for computers as well as computer networks but it also encompasses other technologies which distributes information such as television and telephones.


Cloud Computing- A Simple Definition by Luke Lonergan

Cloud Computing- A Simple Definition by Luke Lonergan

We hear it often but do you really know what the term cloud computing means? Most people have no clue and I want to give you an easy way to understand the concept.

Seriously—no kidding here—many people think of clouds in the sky when you mention “the cloud” or “cloud computing”. Some people even think it is a weather condition combined with technology somehow.

So let’s talk about what this term really means.

cloud-computing-luke-lonerganWhen someone is using a device such as a laptop or even a smartphone and they are accessing information that is stored somewhere other than on their individual device, that’s basically cloud computing. Think of your smartphone. iPhone as a service they call iCloud where all the contents of your phone (pictures, contacts, applications, etc.) are stored on a server that is hosted by Apple so you can access that data in the event your device fails to work anymore. Some other real world examples are when you shop online and they store your information for future purchases or when you do online banking.

Simply put, cloud computing can be defined as something that:

-Is accessible from any location

-Must be remotely stored or hosted

-Is measured in terms of storage and bandwith (pay for usage)

But let me make it even simpler…cloud computing is akin to the internet as a whole. Don’t get too caught up in the term. Just understand that when you use any device to connect to information that is stored remotely, you are basically accessing the cloud and participating in cloud computing.
