Ebajo , FhL G-10-ICT-Lesson 1: Basics of ICT Introduction ICT Stands for Information and Communications Technology ICT refers to the concept of using technology to get information. ICT involves the use of computers and other electronic devices to access information easily and quickly. Examples of Information and Communications Technology include not only personal computers but also new forms of telephones, televisions, appliances, and various hand held devices.

3. By: Sr. Mary Josette B. Ebajo , FhL ICT refers to technologies that provide access to information through telecommunications. It is similar to Information Technology (IT), but focuses primarily on communication technologies. This includes the Internet, wireless networks, cell phones, and other communication media . Components of ICT System ICT usually consists of the following components: Hardware : Physical components of the computer Software : Programs that perform instructions Data : Raw facts that fed to the computer People : Data are entered and used by humans The Internet : It is modern communication technology

5. By: Sr. Mary Josette B. Ebajo , FhL Garbage In, Garbage Out ( GIGO ) Computers operate using strict logic. Because of this fact  invalid input may produce invalid output, or “ garbage ”. ICT systems cannot function properly if the inputs are inaccurate or faulty. They will either not be able to process the data at all, or will output data invalid data. GIGO is a useful term to remember in the examination GIGO can help explain many issues such as why validation is needed and why accurate data is valuable.
