, Preface
The curriculum and curricular materials have been developed and revised on a regular
basis with the aim of making education objective-oriented, practical, relevant and job
oriented. It is necessary to instill the feelings of nationalism, national integrity and
democratic spirit in students and equip them with morality, discipline and self-reliance,
creativity and thoughtfulness. It is essential to develop in them the linguistic and
mathematical skills, knowledge of science, information and communication
technology, environment, health and population and life skills. it is also necessary to
bring in them the feeling of preserving and promoting arts and aesthetics, humanistic
norms, values and ideals. It has become the need of the present time to make them
aware of respect for ethnicity, gender, disabilities, languages, religions, cultures,
regional diversity, human rights and social values so as to make them capable of
playing the role of responsible citizens with applied technical and vocational
knowledge and skills. This Learning Resource Material for Computer Engineering has
been developed in line with the Secondary Level Computer Engineering Curriculum
with an aim to facilitate the students in their study and learning on the subject by
incorporating the recommendations and feedback obtained from various schools,
workshops and seminars, interaction programs attended by teachers, students and
parents.
In bringing out the learning resource material in this form, the contribution of the
