SERVERS

1. WHAT IS A DNS SERVERS?

   • A DNS (Domain Name System) server is a crucial part of the internet infrastructure that translates human-readable domain names (like "example.com") into IP addresses (like "192.0.2.1") that computers use to identify each other on the network.
     • When you type a domain name into your web browser, your computer queries a DNS server to find the corresponding IP address so it can connect to the correct web server.

2. WHAT IS A FILE SERVERS?

   • A file server is a computer or a storage device that is set up to store and manage files that can be accessed by other computers on the same network.
     • It acts as a central repository for files, making it easier for users to share and access files across the network.
     • File servers are commonly used in businesses and organizations to store documents, images, videos, and other types of files that need to be shared among multiple users.

3. WHAT IS A SERVER?

   • A server is a computer or a software program that provides functionality or resources to other computers, known as clients, over a network. Servers can serve various purposes, such as hosting websites, managing email, storing files, or providing access to databases.
     • They typically have more powerful hardware and software than regular desktop computers to handle the demands of serving multiple clients simultaneously

4. WHAT IS CLOUD COMPUTING?

   • Cloud computing refers to the delivery of computing services—including servers, storage, networking, databases, analytics, software, and intelligence—over the internet ("the cloud") to offer faster innovation, flexible resources, and economies of scale. You typically pay only for cloud services you use, helping lower your operating costs, run your infrastructure more efficiently, and scale as your business needs change.

5. 2 OPERATING SYSTEM FOR SERVERS?

   • Linux: Linux is a free, open-source operating system that is widely used for servers due to its stability, security, and flexibility. There are many distributions of Linux available, such as Ubuntu, CentOS, and Debian, each with its own strengths and characteristics.
   • Windows Server: Windows Server is a server operating system developed by Microsoft. It offers a range of features tailored for enterprise-level tasks such as managing users, resources, and services. Windows Server also provides integration with other Microsoft products and services.

6. WHAT SHOULD BE TAKEN INTO ACCOUNT IN THE STRUCTURE OF SERVER?

   • When structuring a server, it's crucial to consider various factors for optimal performance, security, and scalability. Begin by determining the hardware requirements based on the expected workload, including CPU, RAM, storage, and network capabilities. Selecting the appropriate operating system is essential for compatibility and ease of management.

7. THE RELATIONSHIP BETWEEN CLIENT-SERVER

   • The relationship between a client and a server is integral to networked computing, where clients, such as web browsers or applications, send requests to servers for services or resources over a network. Servers, in turn, process these requests, providing the requested data or performing actions, and then send back responses to the clients. This request-response model facilitates communication and data exchange between distributed systems, enabling a wide range of internet-based services and applications to function efficiently and reliably.
