Study Notes
Chapter 1: Introduction to Computer
- This chapter introduces fundamental computer concepts.
- Computers are electronic devices that operate based on instructions stored in their own memory. Their main function is accepting data (input), processing it, and producing information (output).
- Key computer types include laptops, tablets, desktops, all-in-ones, and servers.
- Mobile and game devices such as smartphones, digital cameras, portable media players, e-book readers, wearable devices, and game devices are also covered.
- Data and information are distinguished: data is raw, unorganized facts, while information is processed data presenting meaning.
- Input methods like keyboards (physical and on-screen), pointing devices (mice, touchpads), voice input, and scanners are discussed.
- Output devices such as printers (including 3D printers), displays (various types), speakers, and headphones enable communication of processed information.
- Memory is vital for storing instructions and data, crucial for computer operation. Storage devices (like hard drives, solid-state drives, USB flash drives, memory cards, optical discs, and cloud storage) are described.
- The World Wide Web (the web) is a vast network of interconnected electronic documents (webpages), forming websites accessed via web servers.
- Search engines enable quick retrieval of information from the many webpages. Browsers are applications enabling users to access webpages.
- Social networking websites allow users to interact, share, and communicate with other online users.
- Digital security involves protecting computers and devices from threats like viruses, malware, and ensuring privacy. Environmental concerns, health concerns and green computing practices, such as recycling and energy efficiency, are also discussed.
- Software, like programs and apps, controls tasks and interactions for optimal performance.
- Key software types include operating systems, tools, and applications.
- The process involved in setting up and using different programs (installing, initiating, and interacting via user interfaces).
- Software developers or programmers create software and applications for data-to-information conversion.
- Communications and networks involve technologies enabling data exchange (e.g., chat rooms, email, fax, FTP, GPS, instant messaging, internet, newsgroups, RSS, video conferencing voice mail, VoIP, wireless internet access points, and wireless messaging services).
- Communications devices enable transfer between computers and transmission media (e.g., modem/router/wireless access points).
- Wireless technologies such as Wi-Fi, Bluetooth, and cellular radio are presented as options for network connection.
- Networks are computer/device collections connected via communications devices and transmission media; these can be home or business networks.
- Applications of technology are present in a variety of fields (e.g., education, government, finance, retail, entertainment, health care, science, travel, publishing, and manufacturing.)
- Understanding how different types of users (home, small/home office, mobile, power, enterprise) interact with technology is important.
