Information Technology: Objectives and Functions

In general, a study of design, implementation, development, support or management of computer-based information systems, especially in the application of hardware (hardware) and software (computer software). Simply put, the understanding of information technology is the facilities consisting of hardware and software in supporting and improving the quality of information for every level of society quickly and quality. Meanwhile, according to Wikipedia, the understanding of Information technology (IT) is a general term of technology to assist humans in making, changing, storing, communicating, and disseminating information. The purpose of information technology is to solve a problem, open creativity, increase effectiveness and efficiency in human activities.

Understanding Information Technology (IT) According to Experts

1. Haag and Keen (1996): Understanding of information technology according to Haag and Keen that information technology is a set of tools that help you work with information and perform tasks related to information processing. 2. Oxford English Dictonary (OED): Information technology is hardware and software and can include networks and telecommunications which are usually in a business or business context. 3. Williams and Sawyer (2003): According to Williams and Sawyer, that the notion of information technology is technology that combines computing (computers) with high-speed communication lines that carry data, voice, and video. 4. Martin (1999): According to Martin, information technology is a technology not only in computer technology (hardware and software) that will be used to process and store information, but includes communication technology to send or disseminate information.

Information Technology Function

From information technology, including the following:
1. Capture Capture here can be interpreted as inputting. For example, receiving input from the mic, keyboard, scanner, and others.
2. Processing (Processing) Processing or processing data entered received to become information. Processing and data processing can be in the form of converting, analyzing, and calculating (calculation).
3. Generating (Generating) Produce or organize information into useful forms or reports that can be understood by others. For example, such as reports, tables, graphs and images.
4. Storing (Storage) Recording or storing data and information in a media that can be used for other purposes. Examples are saving to hard disk, flash disk, tape, and others.
5. Searching Back (Retrival) Browse and retrieve information or copy data and information that has been stored. For example looking for sales data that has been previously stored.
6. Transmitting (Transmission) Sending data and information from one location to another through a computer network. For example, by sending sales data from user A to another user.

Thus information about the understanding of information technology, objectives, and functions. Hopefully it can be useful for all of us both in helping our daily activities related to technology needs and getting information.

Information Technology and Development

Information Technology is concerned with the design and development of computer-based systems, which are implemented in hardware and software. The Faculty of Information and Communication Technology is an expert printer with profound computer technology skills and mastering the technical problem solving needed, in line with the modernity of the times. The departments which take shelter in the Faculty of Information and Communication Technology are Informatics, Information Systems, and Information Technology.

The development of information technology today almost all sectors of humans use information. in social and political life technology is never separated from life, there are various things that are new in the world of technology whether dynamic or innovative are its main characteristics. based on daily needs many can not be separated from technology.

Information technology has many interesting things that we can get, such as new things, which until now have been interested in it. information technology or in short with IT in its development in this era not only offers the latest innovations, there are also many infrastructures which in their manufacturing need a lot of the latest technologies that are needed in this era.

Information technology (IT) has a very broad scope. When we review this theme it will usually connect other aspects outside it which in reality are interrelated with one another, for example information and communication technology. in general will touch each other. In general, the understanding of information technology or IT is all matters relating to the mechanism of using certain devices to process including information modification.

The application of IT can also be identified in other areas that are needed to effectively convey the information itself. Areas that have applied information technology or IT are:

Field of education
The application of IT in the education sector can be identified by the existence of E-Learning, which is a kind of online learning system via the internet. With this facility it is possible for teachers and students to keep interacting without having to face-to-face for certain activities such as sending assignments and materials.

Business Field
Information technology (IT) has also been adopted in the business sector with products in the form of E-Commerce. The existence of E-Commerce is able to facilitate business people in conducting commerce activities online on the internet. All trading activities such as promotions, trading transactions can be accommodated properly and effectively.

Banking sector
The application of IT in the banking world can be seen from the mode of online banking transactions on the internet or more popularly called Internet Banking. With this facility, users can carry out certain activities such as checking balances, transferring money between accounts via their own devices such as computers, cellphones etc.

Of course the relevant devices must be connected to the internet and have activated Internet Banking at the bank where they are customers. The use of Automated Teller Machines (ATMs) is also one of the applications of information technology that has been around for a long time.
