Question One:a) Internet Protocol (IP):Internet Protocol (IP) is a set of rules that govern the format of data sent over the internet and the addressing scheme for computers connected to a network. It is the primary communication protocol used for transmitting data between devices on the internet.b) Difference between a Server and a Host:A server is a computer system that provides services to other computer systems (clients) over a network. It stores, processes, and delivers data to the clients upon request. A host, on the other hand, is a general term for any computer connected to a network. While a server is a specific type of host that provides services to other hosts, not all hosts are servers.c) Definitions in Web Programming:i. Data: In web programming, data refers to the information that is stored, processed, and manipulated by a computer system. It can be in various forms such as text, numbers, images, or audio files.ii. Database: A database is a structured collection of data that is stored and organized in a specific manner. It allows for efficient storage, retrieval, and manipulation of data.iii. Open Database Connectivity (ODBC): ODBC is a standard protocol that allows different applications to access data from various databases. It provides a uniform interface for accessing data from different database management systems.iv. Variable: In web programming, a variable is a named storage location that holds a value. Variables can be used to store and manipulate data within a program.d) Differences between Client-Server Computing and Peer-to-Peer Computing:i. In client-server computing, the server provides services to the clients, while in peer-to-peer computing, all nodes can act as both clients and servers.ii. Client-server computing typically requires a centralized server, while peer-to-peer computing does not require a central server.iii. In client-server computing, the server has more control over the network, while in peer-to-peer computing, each node has equal control.e) Web Administrator and Web Administration:A web administrator is responsible for managing and maintaining a website. They handle tasks such as updating content, ensuring website security, and troubleshooting technical issues. Web administration involves the overall management and maintenance of a website, including tasks like content management, security, and performance optimization.f) Function in JavaScript:In JavaScript, a function is a block of code that performs a specific task. Functions allow for code reuse and modularization. Functions can be defined using the `function` keyword followed by the function name and a set of parentheses containing the parameters. Functions can also be called or invoked using their name.g) Including JavaScript in HTML:To include JavaScript in an HTML file, you can use the ````In this example, the JavaScript file named `script.js` is included in the HTML document using the `` tag.
