Read the case situation given below and answer the questions:
Information Technology is the system or method used to collect, store, process data into information and exchange that information all over the world by using computer and communication technology. It is a widely used term that describes the combination of computer technology (hardware and software) with telecommunication technology (data, image, voice, and network). Information Technology can be used in various sectors such as education, health, agriculture, tourism, trade other sectors, etc. Information Technology can be used to promote e-commerce, e-education/e-learning, e-health, etc.
IT applications are everywhere in modern business and their great advantage is the way that they can lower cost. One way that costs can be lowered is in time-saving. For example, time is saved in the retrieval of information from a database or website. Rapid searches can be carried out by simply cueing in a keyword such as the name of the customer or a component. Another way that time can be saved is in the rapid duplication of information. For example, an e-mail can be sent to all of the relevant members of an organization simply by creating a pre-prepared mailing list for all communications of a certain type. The material can be rapidly edited and altered using modern desktop computers.
This system can be used for the development of a knowledge-based society, knowledge based industry, and accessibility of information to the general people. Some of the modern and emerging fields of information technology are web technologies, bioinformatics, cloud computing, global information systems are driven by computer science. Information Technology enables the global communication of information, as well as the global retrieval of information from databases and websites regardless of geographical distance.
