Data Communication & the Cloud - Research Paper Example The components of data communication include the message i.e. the information or data to be communicated and popular forms include text, numbers, pictures, audio and video. The sender is an important component as it is the device that sends the data message as it can be computer work station, telephone handset or a video camera as the receiver is the device on the other end receiving the information as the transmission medium is the physical path by which a message travels from the sender to receiver e.g. twisted pair wire, coaxial cable, fiber optic cable and radio waves. Data communication and other aspects such as networking are changing the way business is done and the lifestyle of people in the world today. Business decisions have to be made even more quickly and the decision makers required access to accurate information relevant to the subject at hand. Computer data communication models in the world today enable the transfer of information through long distances and the inform ation appears almost instantaneous through computer networks2. Businesses today rely on computer networks and internet works in relaying the information across varied distances in modes that enable the efficient communication of data and the development of personal computers brought about tremendous changes for business, industry, science and education as a similar revolution is occurring in data communication and networking. Technological advances are making it possible for communication links to carry more and faster signals and as a result services are evolving to allow the use of this expanded capacity. An example is the establishment of the telephone services such as conference calls, call waiting, voice mail and caller ID has been extended as research in data communication and networking too resulted in new technologies. Data communication in the form of text, audio and video from all points of the world has been made possible due to the access of internet to download and uplo ad information quickly and accurately at any time. As the information is being sent and received, there is need for the security of the message as to avoid distortion and third party interference. On the other hand the storage and speed has led to the invention and introduction of a cloud computing concept. Cloud computing is a new key discipline of high performance computing sophisticated information technologies in order to treat some of the major high performance computing challenges enabling trusted technical computing solutions for the 21st century customers. It is a technology that allows consumers and businesses – generally the users - to use applications without installation and access their personal files at any computer with internet access and also allows for much more efficient computing by centralizing storage, memory, processing and bandwidth as well as provide information techn
