A STUDY ON COMPUTER FUNCTIONAL LITERACY AMONG HIGHER SECONDARY SCHOOL STUDENT...S. Raj Kumar
The present study focuses on Computer Functional Literacy of Higher Secondary School students. Computers are continuously being applied to new careers and used in innovative field all the occasion. The skill not only to use computers, but to adapt to progress and added changes in computing technology is essential to any professional-minded person. This ability to apply old information to latest milieu not just allows for the use of computers but can enhance productivity and even pleasure in one's work. This study steps to truly make aware the students for a computer intensive future and this study results revealed that computer functional literacy of higher secondary school students is in moderate level. Normative survey method was used in the present study and Random sampling technique was used. Variables such as types of management, medium of instruction, computer knowledge and locality of the students are significantly differ in this study.
Keywords: Computer, Literacy, Computer Functional Literacy, Higher Secondary School students.
What is computer Introduction to Computing Ahmad Idrees
Computers make it easier to do a lot of things, but most of the things they make it easier to do don't need to be done.
Computers are useless. They can only give you answers.
This chapter will refresh your knowledge on the basics of how computers work, the different types of computers there are and their typical features. You will then learn about how computers are categorised and how ICT has made the workplace faster and more efficient.
