2. What is a server?

   • A server is a computer or software program that provides services, resources, or data to other programs or devices, known as clients, on a network. Servers can have various functions, such as storing files, managing emails, hosting websites, among others.

3. What is a file servers?

   • A file server is a type of server that stores and manages files for users on a network, allowing them to store, access, and share files from a centralized location. They are commonly used in businesses and organizations to facilitate collaboration and data management among employees. Users can access files on the file server based on their permissions and credentials, making it easier to organize and secure data within the network.

4. What is a DNS servers?

   • A DNS server, which stands for Domain Name System server, is responsible for translating domain names (like www.example.com) into IP addresses that computers use to communicate over a network. When you enter a website's domain name in your browser, your computer requests the DNS server to find the corresponding IP address.

5. the relationship between Client - Server.

   • the client-server relationship in computing is essential. The client, which can be a device or an application, requests services from the server, which is a computer or program that provides those services. Clients send requests to servers, and servers respond with the requested information. This relationship enables efficient communication over networks like the internet, where servers handle multiple client connections.

6. What should be taken into account in the structure of a server

   • When designing a server structure, it's crucial to consider factors such as appropriate hardware, secure operating system, network configuration, robust security measures, regular backups, scalability, monitoring, and maintenance. These elements ensure optimal performance, security, and growth potential.

7. present 2 operating systems for servers?

   • There are several operating systems commonly used for servers, such as Linux, Windows Server, Unix, VMware ESXi, Docker, and IBM i. Each one has unique characteristics and is chosen based on the server environment needs, compatibility with existing software/hardware, and security requirements.

8. What is Cloud computing?

   • Cloud computing is a service delivery model for computing over the internet, allowing access to computer resources based on needs and paying only for what is used. It offers advantages such as scalability, flexibility, cost savings, security, and automatic updates. There are different cloud service models (IaaS, PaaS, SaaS) with varying levels of control.
