Comp 012 : Computer Skills Preparatory Program of: College of Medicine and College of Dentistry Semester: I - 1433-1434 By: Dr. Yosry Azzam Comp 010 1 WELCOME Comp 010 2 Lecturer Name: Riyadh Almushrafy Email: R.almushrafy@mu.edu.sa Tel: 064044035 – Ext 4035 Bachelor in IT QUT – Australia 2009 Master in IT Monash – Australia 2011 Manager of e-learning and IT Unit Comp 010 3 Objective: This course is aimed to provide a fundamental understanding of computer science for the students in their early stages of academic career. Since informatics is one of the basic topics that students in health and medical sciences should study at college, the Orientation Program offers a basic information technology course. This is a computer literacy course that introduces students to computers and their importance in society. The course covers the basic terminology in terms of Hardware, Software, Communication, and Internet. In addition, the course has a large practical part dedicated to train students to use the basic application software. This will enable them to use computers in a way to optimize their work and make it professional and efficient as possible. The course is meant to provide essential acquaintance for students with no previous background in computers. Prerequisite: None.
