input device

An Input device is any piece of computer hardware equipment used to provide data and control signals to an information processing system (such as a computer). Input and output devices make up the hardware interface between a computer and the user or external world.

Typical examples of input devices include keyboards and mice. However, there are others which provide many more degrees of freedom. In general, any sensor which monitors, scans for and accepts information from the external world can be considered an input device, whether or not the information is under the direct control of a user.

belajar ict

ICTL untuk sekolah menengah ini sebagai satu panduan untuk guru-guru dan pelajar yang belajar ICT Literacy
Bermula dengan program Komputer Dalam Pendidikan (KDP) pada tahun 1992 program ini telah diubah kepada Program Literasi Komputer pada tahun 2002 sehingga 2005 program ini telah disemak semula selari dengan perkembangan teknologi maklumat dan komunikasi sekarang. bermula julai 2007 program ini sekali lagi ditukar kepada ICTL ( information communication Technology Literacy) dengan bermatlamatkan
• memperolehi pengetahuan ICT dan kemahiran-kemahiran kreatif untuk membantu mereka dalam kehidupan harian mereka;
• berkongsi hemat dan maklumat di kalangan mereka sendiri, di dalam dan melebihi persekitaran sekolah; DAN
• menunjukkan tanggungjawab dan akauntabiliti ke arah infrastruktur ICT yang digunakan.

INTRODUCTION TO COMPUTER

Computer is an electronic device operating under the control of instructions store in its memory unit, that can accept data (input). process data arithmetically and logically, Produce result ( output) from the processing and store the results for future use.

The Evolution of the Computer

1. First Generation (1939-1954) - vacuum tube
2. Second Generation Computers (1954-1959) - transistor
3. Third Generation Computers (1959-1971) - IC
4. Fourth Generation (1971-1991) - microprocessor
5. Fifth Generation (1991 and Beyond)

Ethics in using computer

Example Topics in Computer Ethics

No matter which re-definition of computer ethics one chooses, the best way to understand the nature of the field is through some representative examples of the issues and problems that have attracted research and scholarship. Consider, for example, the following topics:

• 3.1 Computers in the Workplace
• 3.2 Computer Crime
• 3.3 Privacy and Anonymity
• 3.4 Intellectual Property
• 3.5 Professional Responsibility
• 3.6 Globalization
• 3.7 The Metaethics of Computer Ethics

(See also the wide range of topics included in the recent anthology [Spinello and Tavani, 2001].)
