Technology Makes The World Go Around

The word cloud in cloud computing is used to describe the Internet so cloud computing means a type of Internet-based computing, where different services including including servers, storage and applications are delivered to an organization's computers and devices through the Internet. In other words, it is using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer. It is an on-demand service that works for corporate data centers as it enables the data center to operate like the Internet and computing resources to be accessed and shared as virtual resources in a secure and stable manner.  It began in the enterprise and shift to adoption by small business owners as cloud computing is taking services  and moving them outside an organizations firewall on shared systems as applications and services are accessed via the Web, instead of your hard drive. The services are delivered and us...

Software testing is a process that is implemented to check the quality and result of the software or application being developed.  It is done to allow the companies to understand and appreciate the risks that are involved during software implementation.  It helps to point out the defects and errors that were made during the development phases and is used to makes sure of the customer reliability and satisfaction in the application. Testing allows developers to deliver software that meets expectations, prevents unexpected results, and improves the long term use of the application. It also depends the purpose of testing and the software requirements, the appropriate methodologies are applied.     Test techniques include the process of executing a program or application with the intent of finding bugs,errors or other defects, and verifying that the software is fit for use. You need to verify that the completed software package functions according ...

One of the most important skills any computer user should have is the ability to use a virtual private network (VPN) to protect their privacy.   Virtual Private Networks or VPN is a way for users to securely access a private network and share data remotely through public networks. It works much like a firewall the difference being a firewall protects your data on your computer, whereas VPNs protect it online. Although a VPN is a Wide Area Network, the front end has the same functionality, security, and appearance as it would on the private network. The Internet for all its connectivity is unreliable and is still a digital jungle where hackers can easily steal sensitive information from the ill equipped when it comes to public networks, and this is where VPN comes in. If you work remotely and need to access sensitive data on your company's private servers, doing so from an unsecured public network like a coffee shop WI-Fi hotspot could put that data, your company...

Computer programming languages allow us to communicate with a computer in a language the computer understands. There are an many computer programming languages that programmers can use to communicate with a computer and the language that a computer can understand is called a binary. The process of translating programming language into binary is known as compiling and each language, from C Language to Python, has its own features, although there are similarities between programming languages. These languages allow computers to quickly and efficiently process large and complex bits of information in real time without errors. There are many programming languages that are used today in the information technology industry to facilitate communication. One of them is Python which is an advanced programming language that is interpreted, object-oriented and built on flexible and robust semantics.   Next we have Java which is a all purpose, object oriented, high-level program...

Software can be defined as a set of computer programs that can control, manage, direct and support all operations of a computer system.  Computer programs need sets of instructions known as software so that computers can run and execute given tasks.  Software can also make up the different parts of a computer, instructions that are needed for it to run and do what it is supposed to do.    A computer system consists of software components that have no physical presence as they are stored in digital form within computer memory.  There are different categories of software, including system software, utilities and applications software.  A lot of instructions, are stored digitally within the computer's memory, which makes the computer function accordingly. Any application program is dependent on the system software found in the computer to deliver specific functionality to a user.  There are several minor application programs, also ...

A smartphone is more like a mini computer that can also place and receive calls and have apps that  turn your phone into something much smarter than a regular cell phone. It is a mobile device that performs many of the functions of a computer, typically having a touchscreen interface, Internet access, and an operating system capable of running downloaded applications It is a device that differs from you regular phone as it lets you make calls, but also includes features that were found only on a personal digital assistant or a computer such as the ability to send and receive e-mail and edit and view Office documents. Before the coming of the smartphone , there were cell phones that were used for making calls, while devices like the Palm Pilot, were used as personal digital assistants or portable organizers that could store your contact information and could synchronize data with your computer. Smartphones, have changed the way we communicate because of their mu...

Code can be defined as a set of instructions in a language that computers can understand; and it is what makes it possible for us to create different computer software, apps and websites that we use including the browser, the operating system, the apps present on your phone, social media sites etc. are all made with code.   Computer coding is a process that leads from an original forming of a computing problem to a computer program that works. Codes play an important role in our lives as code is what makes computers work and computers are integrated with many objects and electronic devices that we use daily like phones, watches, microwaves and cars. People who code are known by different names such as coders, programmers, developers, computer scientists, software engineers, etc. Computers are nothing but machines that run on binary code written in 1s and 0s which is very difficult for humans to work with. Computers like people can understand different la...
