FINLANDIA SCHOOLThe internet, short for "interconnected network," refers to a global system of interconnected computer networks that communicate with each other using standardized protocols. It is a vast network infrastructure that enables the exchange of information and communication across different devices and locations worldwide.
The internet is not a physical entity but rather a network of networks that includes millions of private, public, academic, business, and government networks. These networks are connected through various wired and wireless technologies, such as fiber-optic cables, satellite links, and radio waves.
The internet allows users to access a wide range of services and resources, including websites, email, social
media, online applications, file sharing, streaming media, and much more. It has revolutionized the way people communicate, collaborate, access information, conduct business, and entertain themselves.
The internet relies on a set of protocols known as the Internet Protocol Suite (TCP/IP), which provides a standardized framework for data transmission and routing. These protocols ensure that data packets can be sent and received across different networks, allowing seamless communication between devices and systems regardless of their location.
BASIC INTERNET TERMINOLOGIES:
- IP Address: (Internet Protocol address) is a unique numerical label assigned to each device
connected to a computer network. It serves as the device's identifier on the internet, allowing it to send and receive data.
- URL: Uniform Resource Locator is the web address used to locate a specific resource on the internet. URLs typically include the protocol (e.g., http:// or https://), the domain name, and the specific path to the resource.
- Browser: A web browser is a software application used to access and view websites on the internet.
Popular browsers include Google Chrome, Mozilla Firefox, Microsoft Edge, and Safari.
- Search Engine: A search engine is a tool that enables users to search for information on the internet.
Examples of popular search engines are Google, Bing, Yahoo, and DuckDuckGo.
- HTML: HTML (Hypertext Markup Language) is the standard markup language used for creating web pages. It uses tags to structure the content and define the elements and layout of a webpage.
- HTTP and HTTPS: HTTP (Hypertext Transfer Protocol) is the protocol used for transmitting data between a web server and a web browser. HTTPS (HTTP Secure) is a secure version of HTTP that encrypts the data transmitted between the server and the browser, ensuring a secure and private connection.
- DNS:(Domain Name System) is a decentralized naming system that translates domain names (e.g., www.example.com) into IP addresses. It allows users to access websites using human-readable domain names instead of remembering complex IP addresses.
- Firewall: A firewall is a security device or software that monitors and controls incoming and outgoing network traffic. It acts as a barrier between a trusted internal network and untrusted external networks, protecting against unauthorized access and malicious activities.
- Router: A router is a networking device that connects multiple networks together and forwards data packets between them. It determines the most efficient path for data transmission and enables devices within a network to communicate with devices on other networks.
- ISP: (Internet Service Provider) is a company or organization that provides internet access to users.
ISPs offer various types of internet connections, such as broadband, DSL, cable, fiber, or satellite,
allowing users to connect to the internet.
Web Page: A web page is a single document or resource on the World Wide Web that is accessible through a browser. It can contain text, images, videos, hyperlinks, and other multimedia elements. Web pages are written using HTML and are the building blocks of websites.
- Website: A website is a collection of related web pages that are grouped together and accessible under a common domain name. It represents a specific entity or organization on the internet and typically includes a homepage, multiple interconnected pages, and various multimedia content.
- Home Page: The home page is the main or starting page of a website. It is the first page that users see
when they visit a website. The home page often provides an overview of the website's content,
navigation options, and links to other sections or pages within the site.
- Hyperlink: A hyperlink, commonly referred to as a link, is a clickable element on a web page that connects to another web page or a different section within the same page. It is usually represented by
underlined text or an image. Clicking on a hyperlink redirects the user to the linked content.
- Internet Protocol Suite: The Internet Protocol Suite, commonly known as TCP/IP (Transmission Control Protocol/Internet Protocol), is a set of protocols that governs communication over the internet. It provides a standardized framework for data transmission, addressing, and routing between devices and networks.
- SMTP: SMTP stands for Simple Mail Transfer Protocol. It is a protocol used for sending and receiving email messages over the internet. SMTP is responsible for the transfer and delivery of emails between mail servers.
- Modem: A modem is a device that enables communication between a computer or network and an internet service provider (ISP). It converts digital signals from a computer into analog signals that can be transmitted over telephone lines, cable lines, or other communication channels, and vice versa.
- Blogs: Blogs are online platforms or websites where individuals or groups regularly publish content in a chronological order. They often contain articles, personal experiences, opinions, or informational content on various topics. Blogs allow readers to engage with the content through comments and provide an interactive platform for sharing ideas.
- Intranet: An intranet is a private network that operates within an organization. It uses internet technologies and protocols but is accessible only to authorized individuals within the organization.
Intranets are used to share information, collaborate, and streamline communication within a company or institution.
