Study Notes
Web Development Course Notes
- Polytechnic University of the Philippines, Santa Maria, Bulacan Campus
- Course Code: COMP 016
Part I: Introduction to Web Development
- Overview: This lesson introduces basic concepts of the Internet and web technologies. It focuses on standard user-centric website design.
- Learning Objectives: Students should be able to define Internet, Intranet, and World Wide Web, understand how the Internet works, recognize the difference between intranet and Internet, familiarize themselves with web development technologies and features, understand industry standard user-centric website design, and understand the importance of websites.
The Internet
- Definition: A worldwide system of computer networks where users can access information from any other computer with permission. The Internet is often described as an information superhighway.
- Functionality: People can share information and communicate worldwide through the Internet.
The Intranet
- Definition: A private network of computers within an organization. It is used to securely share company information and resources among employees.
- Uses: Intranets are used for communication, accessing important information (links, forms, databases), and also in group work and teleconferences, and to maintain security for employee access rights.
The World Wide Web (WWW)
- Definition: Interconnected web pages and information accessible through the Internet. The Web is used to help users share, and find information easily.
- Functionality: Used to browse websites, watch videos, shop online, and connect with people worldwide.
- Data Presentation: Data on the web can be presented in various formats: text, images, audio, and video.
How the Internet Works
- Concepts: Packets and protocols are fundamental to the Internet's functionality.
- Packet Routing: The Internet uses a packet routing network based on protocols like the Internet Protocol (IP), Transport Control Protocol (TCP), and others.
Packets
- Definition: Small segments of larger messages transmitted across the network.
- Header Information: Each packet contains a header with information about the packet's content to guide the receiving machine.
Protocols
- Definition: Standardized rules and methods that enable devices to communicate efficiently. Protocols like Ethernet (for same network communication), IP (network to network packet transmission), TCP (guaranteed order of packet delivery) and HTTP (web data formatting) are used.
- Function: Protocols allow devices to exchange data and understand each other to enable effective communication.
- Importance: The Internet functions consistently because all devices comply with these protocols.
TCP vs IP
- TCP and IP protocols work together to ensure data delivery to intended destinations within a network.
- IP defines the intended destination address (IP address). TCP takes responsibility for transporting the data to that destination across the network architecture.
- Function: They cooperate to enable effective communication and data transfer over long distances.
Internet Protocol (IP)
- Function: The method for sending data from one device to another across the Internet.
- Importance: Every device has a unique IP address for communication and identification processes. Today it is a standard for communication between devices.
Transmission Control Protocol (TCP)
- Function: A communications standard that enables application programs and computing devices to exchange messages across a network by sending packets and ensuring messages are received in order.
- Importance: This functionality ensures the successful delivery of data and messages across networks.
Part 1: Introduction to Web Development
Key Differences: Internet vs Intranet
- Internet: A wide network accessible by all users..
- Intranet: A network limited to a specific group.
WebDev Technologies
- HTML (HyperText Markup Language)
- CSS (Cascading Style Sheets)
- Programming Languages (e.g., JavaScript, PHP, Python, Java)
- Web Development Frameworks (e.g., Angular, Node.js)
- Libraries (e.g., React.js, Vue.js, FacebookSDK)
- Databases (e.g., SQL, NoSQL)
HTML:
- Provides the base structure for web pages.
- Formats website content for proper display.
CSS:
- Defines the style and aesthetics of a web page.
- Enhances visual presentation (layouts, colors, fonts).
Programming Languages:
- Enable communication with computers to perform specific functions.
Web Development Frameworks:
- Simplify development by providing reusable code resources and functionalities.
Libraries:
- Enable functionalities by grouping code snippets.
Databases:
- Store, organize, and retrieve large amounts of data, often storing data from applications.
- SQL: Use structured query language (SQL) to define, store, control, and manage data. SQL databases use pre-determined schemas to organize data.
- NoSQL: Enable flexibility in data storage formats without using rigid schemas.
User-Centered Design Basics
- User-centered design (UCD): Aims for useful and usable websites targeting a specific user group.
- Elements: Usability, navigability, and information retrieval are essential factors to consider when designing user-centered sites.
User-Centered Design Process
- Stages: General phases include specifying context of use, requirements, creating design solutions, and evaluating solutions.
- Iteration: Process is iterative, ensuring solutions address user needs effectively.
Importance of Websites
- First impressions: Online presences are crucial in business.
- Wider visibility: Websites help businesses establish a wider presence online.
- Visibility into your business: Websites allow businesses to share their company history and online vision.
- Competitive advantage: Businesses should take advantage of existing online competitors and consider how their own platform can be enhanced to be competitive.
- Attracting talent: Websites are key for acquiring top talent.
- Content marketing: Websites are key to content creation, distribution, and marketing campaigns.
