Applications of Information System Information systems have now become the means through which different IT-enabled services are provided by organizations. These IT-enabled services are usually known as E-services. E-services are defined as the provision of public services using technology as a mode of service delivery. The different types of e-services are:- E-Government E-banking E-learning E-commerce Telemedicine Teleconference E-Government Electronic government or e-Government is the use of information systems to provide electronic services to citizens with the purpose of increasing efficiency, transparency, and citizen participation.

E-commerce E-commerce (electronic commerce) is the buying and selling of goods and services over the Internet. E-commerce is fundamentally a website deployed over Internet to handle online transactions. Buyers go to the E-commerce website using their smartphones or computers when they make an order for a product or service over the Internet. Once the order is received by the merchant, the payment will be processed through the Bank. After the whole transaction is successfully completed, the order will be delivered to the buyer E-commerce In Ethiopia, small businesses which sell different types of products online have mushroomed recently. The flexibility with which customers browse products and compare prices and buy the cheapest offerings contributed to the growth of such types of businesses. e-commerce is at its infancy stage in Ethiopia Advantages of e-commerce Avoiding intermediaries: this mode of business allows customers to buy products directly from manufacturers at a cheaper price avoiding wholesalers and retailers. Convenience: customers can order products from where they are. Increased bargaining power for the customer: customers can easily browse the price of different merchants and choose the least price. Global reach: the Internet made it possible for the merchants to expand their customers outside their local area. This, however, also creates more competition as merchants now compete not only with local competitors but also with global ones. Telemedicine Telemedicine refers to the practice of caring for patients remotely without the caregiver and the patient being in the same physical location. Telemedicine was originally introduced to treat patients who were in remote places, far away from local health facilities There are now different telemedicine companies that provide online treatment.

The patients pay the service fee online through their bank account Telemedicine Advantages of telemedicine Overcoming geographical barriers to access health care services. Reduced cost through avoidance of costs such as travel and hotel services. Access to specialized physicians by people who live in remote locations. Limitations of telemedicine Telemedicine requires technical trainings. Requires equipment, which may not be readily available in the rural areas of developing countries. Teleconference A teleconference is a meeting of two or more people who are separated by distance using electronic communication. The two popular forms of teleconferencing are audio conferencing and video conferencing. Audio conference: it is a voice-only communication, sometimes called conference call, which connects people from remote locations via telephone lines.
