✦ Synopsis

In almost all technical institutions of learning, the laboratory work in any subject runs concurrently with the course in theory of the subject. Consequently, the students perform the laboratory work mechanically without intellectual involvement in the work. It is, therefore, necessary that the students, before conducting the experimental work, are familiarized with elementary theoretical and other aspects relevant to the experimental work. This book is an attempt to serve this objective for the subject of hydraulic engineering.;Cover; Preface; Contents; 1. Information Technology in 21st Century; 2. Network and Internet Technology; 3. Advanced Error Control Techniques in Network; 4. Data/Network Security Techniques and Approaches; 5. Reviewing Information, IT and Looking into Future IT
