GEEL3: General Elective 3: Living in the IT Era  1 OVERVIEW OF IT: DEFINITION AND SCOPE Information Technology (IT) refers to the use of computers, software, networks, and other digital technologies to store, process, transmit, and manage data. It involves the application of technology to solve problems, automate tasks, and enhance communication in various sectors such as business, education, healthcare, and entertainment. In simpler terms, IT is all about using technology to handle and organize information efficiently, whether it’s for personal use, business, or government operations. Key Components of IT: Hardware – The physical devices used in IT, such as: - Computers (desktops, laptops) - Servers and data storage devices - Networking equipment (routers, switches) - Mobile devices (smartphones, tablets) Software – The programs and applications that run on hardware, including: - Operating systems (Windows, macOS, Linux) - Productivity software (Microsoft Office, Google Workspace) - Specialized applications (ERP, CRM systems) Networks – The infrastructure that allows devices to connect and share information: - The Internet and intranet systems - Wi-Fi, fiber optics, and telecommunications networks - Cloud computing services Data Management – IT helps in collecting, storing, and analyzing data through: - Databases (SQL, NoSQL) - Big data analytics - Cybersecurity measures to protect sensitive data People – IT professionals who develop, manage, and maintain technology systems, including: - IT support specialists - Software developers - System administrators - Network engineers The scope of IT is vast and continuously expanding, covering various industries, functions, and aspects of daily life. IT is not limited to computers; it includes a wide range of applications impacting businesses, education, healthcare, government, and personal use. The growing reliance on IT for communication, automation, and decision-making makes it one of the most important fields in the modern world. Key Areas in the Scope of IT: 1. Hardware and Software Development Designing and manufacturing computers, mobile devices, and peripherals. Developing operating systems (e.g., Windows, Linux) and applications (e.g., Microsoft Office, Adobe Photoshop). Emerging trends in hardware like IoT devices, wearables, and smart home systems. 2. Networking and Communication Internet services (Wi-Fi, broadband, 5G networks). Cloud computing platforms like AWS, Microsoft Azure, and Google Cloud. Virtual communication tools such as Zoom, Microsoft Teams, and social media platforms. 3. Data Management and Security Database management systems (e.g., MySQL, MongoDB).
