Concept
A web server is a software or hardware system that serves web pages to users over the internet or an intranet by processing requests via HTTP or HTTPS protocols. It is a crucial component of the internet infrastructure, enabling the delivery of web content and applications to end-users, often working in conjunction with databases and application servers.
Concept
HTTP, or Hypertext Transfer Protocol, is the foundational protocol for data communication on the World Wide Web, enabling the fetching of resources such as HTML documents. It is a stateless protocol, meaning each request from a client to server is treated independently without any stored context from previous interactions.
Concept
HTTPS, or Hypertext Transfer Protocol Secure, is an extension of HTTP designed to provide secure communication over a computer network by encrypting data between the client and server. It uses Transport Layer Security (TLS) to ensure data integrity, confidentiality, and authentication, making it essential for protecting sensitive information online.
Concept
TCP/IP is a foundational suite of communication protocols used to interconnect network devices on the internet, ensuring data is sent and received accurately across diverse networks. It consists of four abstraction layers: link, internet, transport, and application, each serving a specific function in the data transmission process.
The client-server model is a distributed application structure that partitions tasks or workloads between service providers, known as servers, and service requesters, called clients. This model allows multiple clients to access shared resources on a network, providing scalability, centralized control, and resource management.
Load balancing is a method used to distribute network or application traffic across multiple servers to ensure no single server becomes overwhelmed, thereby improving responsiveness and availability. It is critical for optimizing resource use, maximizing throughput, and minimizing response time in distributed computing environments.
Server-side scripting is a technique where scripts are executed on the web server, generating dynamic web pages that are then sent to the user's browser. This approach enhances security and performance by keeping the logic and data processing on the server side, reducing the load on the client's device.
A Content Delivery Network (CDN) is a system of distributed servers that deliver web content and applications to users based on their geographic location, the origin of the webpage, and the content delivery server. This approach enhances the performance, reliability, and speed of websites by minimizing latency and optimizing resource use.
Web hosting is a service that allows individuals and organizations to make their websites accessible via the internet by storing them on servers. It involves various types of hosting such as shared, dedicated, and cloud hosting, each offering different levels of performance, security, and control.
Concept
SSL/TLS are cryptographic protocols designed to provide secure communication over a computer network, ensuring data integrity, confidentiality, and authentication between parties. Widely used in securing internet traffic, they establish an encrypted link between a web server and a browser, safeguarding sensitive information from interception or tampering.
A reverse proxy is a server that sits between client requests and a backend server, forwarding client requests to the appropriate backend server and returning the server's response to the client. It enhances security, load balancing, and performance by masking the identity of backend servers and distributing incoming traffic efficiently.
Concept
Caching is a technique used to store frequently accessed data in a temporary storage location to improve data retrieval speeds and reduce latency. It optimizes performance by minimizing the need to access slower, more resource-intensive storage layers, thereby enhancing overall system efficiency.
Static content stays the same every time you look at it, like a picture in a book. Dynamic content changes, like a video that shows different things each time you watch it.
Hypertext Transfer Protocol (HTTP) is the foundation of data communication on the World Wide Web, allowing for the transfer of hypertext documents between clients and servers. It operates as a request-response protocol in the client-server computing model, enabling web browsers to fetch web pages from servers and display them to users.
The WebSocket Protocol is a communication protocol that provides full-duplex communication channels over a single TCP connection, enabling real-time data exchange between client and server. It is designed to be implemented in web browsers and web servers, allowing for low-latency, bidirectional communication ideal for applications like chat, live updates, and gaming.
Dynamic web pages are web pages that are generated in real-time based on user interactions or other data inputs, allowing for a personalized and interactive user experience. They are typically powered by server-side scripting languages and client-side technologies that work together to fetch, process, and display data dynamically.
Query parameters are components of a URL that allow users to pass data to a web server, enabling dynamic content retrieval and filtering. They appear after the question mark in a URL and are typically used in key-value pairs to specify and control the behavior of web applications.
A POST request is like sending a letter to a website to ask it to do something special, like saving your drawing. It's different from GET requests because it sends information to the website, like your name or a picture you drew, instead of just asking for something back.
URL Mapping is like a treasure map that helps your computer find the right treasure chest of information on the internet. When you type in a web address, URL Mapping tells your computer where to look to find the right webpage you want to see.
Installing the Laravel framework is like setting up a new toy that helps you build websites. You need a few special tools and follow some steps to make it work properly on your computer.
When you ask a website for something, like a picture or a game, your computer sends a message called a web request. The website then sends back what you asked for, and that's how you see things on the internet.
Server-side scripting languages are like magic wands for computers that help them create and send special messages to your computer when you visit a website. They work behind the scenes to make sure the website shows up just right on your screen, like putting together a puzzle so you can see the whole picture.
A web page is like a picture book that lives on a computer called a server, and when you want to see it, your computer asks the server to send it over. The server then sends the web page to your computer so you can see it on your screen, just like magic!
A route definition is like a map that tells a computer how to find different places on the internet. It helps the computer know where to go when you click on links or type in a website address.
When we change an HTTP response, it's like changing a letter before we send it back to someone who asked for it. This can help make sure the letter says exactly what we want or keeps some secrets safe.
A server-side programming language is a special type of computer language used to create the parts of websites that you can't see, like when you log in or when a website remembers your name. These languages help computers talk to each other and do important jobs behind the scenes, like keeping your information safe and making sure the website works properly.
A DELETE request is like erasing a drawing from your notebook; it tells the computer to remove something from the internet. It's important to be careful because once you erase it, you can't get it back easily.
