An Operating System (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs. The operating system is a vital component of the system software in a computer system. Application programs require an operating system to function.
An Application Software, also known as an application or an app, is computer software designed to help the user to perform specific tasks. Examples include enterprise software, accounting software, office suites, graphics software and media players. Many application programs deal principally with documents.
WHAT IS THE MOST COMMON OPERATING SYSTEM AND THE MOST COMMON APPLICATION SOFTWARE?
The two most commonly used operating systems are Windows XP and Windows Vista. If you consider all versions of Windows to be the same product, then the most know about operating systems are windows and mac OS X but Linux is used more than mac.So the two most used operating systems are windows and mac. Microsoft even said that Linux is more of a threat than mac.
Microsoft Office suite, in particular Word is very widely used. Other common applications on personal computers are Adobe Photoshop, Internet Explorer, Firefox, Sahara. Increasingly, software is being run on remote servers – there are network version of some of Microsoft Office, but services such as Facebook, Twitter and so on are application programs that run, largely, on remote servers.
WHAT IS THE DIFFRENCE BETWEEN COMMUNICATION DEVICES AND COMMUNICATION MEDIA?
Communication Media and Communication Devices deliver messages to a receiver or audience. Communication media can be referred to as “media” because a common definition for media inherently includes its purpose in communication. Media is “the means of communication, such as radio and television, newspapers, and magazines, that reach or influence people widely,” according to Dictionary, an online reference site.
Communication devices are the tools used by senders and receivers to deliver and receive message. More specifically, “Communication devices route and transmit information to various devices, including radio and telephone systems,” according to GlobalSpec. Common examples of communication devices noted by GlobalSpec include telephones, cellular phones, wireless and GPS technology systems, radios and transmitters. Specific applications used in conjunction with physical and hardware devices also are noted as “communication devices.” These tools include various communication software applications, magnetic receivers, transmitters, and switchboards.
