INTRODUCTION Information Technology (IT)  CONTENTS INTRODUCTION COMPUTER FUNDAMENTALS COMPUTER COMPONENTS: HARDWARE COMPUTER FUNDAMENTALS ─ SOFTWARE NETWORKS AND INTERNET ARTIFICIAL INTELLIGENCE COMPUTER VIRUSES The purpose of this course is to introduce you to information Technology , Computers , its fundamentals and its application in our life.  The aims of an Information Technology course for pharmacy students presented in points: 1. Enhance Software Skills: Develop proficiency in pharmaceutical and healthcare software applications. 2. Improve Data Management: Teach effective management of health and pharmacy-related data. 3. Understand Information Systems: Familiarize students with pharmacy information systems and their applications. 4. Support Research and Development: Encourage the use of technology in drug research and development processes. 5. Facilitate Communication: Promote the use of IT for better communication within healthcare teams. 6. Ensure Data Security: Instill knowledge about data privacy and security regulations in pharmacy practice. 7. Prepare for Telepharmacy: Equip students with skills for remote patient care and telepharmacy services. 8. Foster Innovation: Encourage innovative thinking in applying technology to improve patient outcomes and pharmacy services.  DATA & INFORMATION DATA is a collection of independent and unorganized facts. INFORMATION is the processed and organized data presented in a meaningful form.  Data: Data is the name given to basic facts such as names and numbers.  Information: Information is data that has been converted into a more useful or intelligible form.  Knowledge: Knowledge arrangement of information and classifying information of the same type or the same topic. 6 Technology  IT & YOUR LIFE 8  Information Technology (IT) Information Technology (IT) describes any technology that helps to produce, manipulate, store, communicate, and/or disseminate information. IT = computer + communications technologies 9  COMPUTER TECHNOLOGY: A computer is a programmable, multiuse machine that accepts data—raw facts and figures —and processes, or manipulates, it into information we can use, such as summaries, totals, or reports. - Its purpose is to speed up problem solving and increase productivity. 10  Why is information technology important? Information technology is important for several reasons, including: 1. Facilitates communication 2. Improves data storage and management 3. Protects critical systems 4. Boosts productivity and efficiency 5. Supports flexible work arrangements  “Information technology refers to anything related to computing technology. The Internet, for example, comes under the umbrella term IT. So does computer hardware, software, and networking.” “Information technology is the design and implementation of computer networks for data processing and communication.” Education - Finance - Healthcare Security - Communication - Employment  DIGITAL AND ANALOG COMPUTERS Digital Computers Definition: Digital computers process data in binary form (0s and 1s). They perform calculations and operations using discrete values. Characteristics: High precision and accuracy. Capable of performing complex calculations quickly. Programmable, allowing for versatility in applications. Examples: Personal computers, smartphones, servers.  Analog Computers Definition: Analog computers process data in a continuous form, representing information with physical quantities (e.g., voltage levels). Characteristics: 1. Suitable for simulating real-world phenomena (e.g., temperature, speed). 2. Often used in specific applications like engineering simulations and control systems. 3. Typically less precise than digital computers but faster for certain tasks. Examples: Slide rules, differential analyzers, early flight simulators. ANALOG COMPUTERS  CHARACTERISTICS OF COMPUTER 1. Speed 2. Accuracy 3. Diligence 4. Storage Capability Large volumes of data and information can be stored in the computer and also retrieved whenever required. 5. Versatility Computer is versatile in nature.
