USES OF NIGC0M-SAT 1

1.        TELEPRESENCE: This means to be present by electronic means in order to render services. It includes tele-education (i.e Distance Learning), tele-medicine (i.e distance curing of illness and disease), e-Government (i.e electronic Government), e-commerce (electronics commerce). In all these the resource persons are not bodily present; instead, they render their services by electronic means.

2.       BROADCASTING: This involves mainly television broadcast.

3.       TELECOMMUNICATION: This involve the use of telephone, mobile phones etc. This will also go a long way to reduce the cost of making phone calls within and outside the country thus bringing the much needed growth of the industrial and commercial sector of the economy.

4.       INTERNET AND MULTIMEDIA: This involves communication and exchange of information through the internet.
