Government policy and the role of key institutions This section deals with the main means by which IT innovation has been encouraged since ; the degree to which the government has been involved in the promotion of IT innovation; and the role of institutions in implementing the IT innovation. The Context of IT Development In general the major commitment of the government to provide the requisite political will and authority for the coordination and promotion of science and technology, its application to development, and overall evaluation of results achieved in the field has been manifested by the establishment of a national commission, the Ethiopian Science and Technology Commission ESTCin by proclamation No.

How the system works the three key concepts Three directions of computer development Three direction of communication development. IT merges computers with communication to make it information technology.

Thus there are two main parts to Information technology: This is a programmable and multiuse machine that accepts data — raw facts and figures an processes or manipulates it into information for future use.

Communication Technology This is also called as telecommunication technology it consists of electromagnetic devices and systems for communication over long distances. Categories of Computers Super Computers: These are high capacity machines with thousands of processors that can perform more than several trillion calculations per second.

They are often called as mid size computers. The mainframe is accessed by its users through a dumb terminal. These are expensive, powerful personal computers used for specific task like designing, 3d animation, engineering calculations etc Micro computers: These are personal computers which are either stand alone or connected over a network.

They are tiny in size with a specialized micro processor installed in it. They are normally found in smart appliances and automobiles. This is a centralized computer that holds the collection of data Database and sharing resources between the clients over the network.

The three concepts which form the frame work for a computer are: A computer Processes Data to give information Data: Data that has been summarized or manipulated to give the required result.

Computer consists of hardware and software Hardware: Physical components of a computer Software: Programs that consists of the instructions that tell the computer how to carry out a specific task.

Computer performs 5 basic operations: Input operation — the data that is given to the system. Eg Keyboard, Mouse, Scanner. Processing Operation — manipulation the computer does to transform the data into information.

Processor chip, mother board Etc Storage Operation — this consists of two types of memory: Modem Three directions of computer development As the time advances the computer has seen its development in the following three directions: Three direction of communication development.

The recent development in communication are: This refers to two way communication where the user can respond to the information they receive and modify what the system is doing. This refers to technology that presents media in more than one medium in a single integrated communication.

Sound Video and Animation.I. Introduction Unlike the invention of a new technology, which often appears to occur as a adoption of new technology is characterized by 1) uncertainty over future profit streams, 2) irreversibility that creates at least some sunk costs, and 3) the opportunity to delay.

“information technology,” as applied to teaching and learning. Access for all and examples of effective and ineffective attributes of information technology applications were also proposed as issues in need of further discussion, as was the true costs of using information technology on a large-scale.
