WHAT IS A SERVER?
A server is a high-capacity, high-powered computer designed to store information. This computer is part of a network where other computers have access to the stored information. The goal is to make the information readily available to the computers connected to the server.
Server machines have more storage and memory capacity than a typical computer, due to the service they must provide to multiple computers. Servers are usually located in companies, centralizing and storing the large amounts of data generated.
Server components
- Operating system: Software that handles the basic processes of a computer and facilitates the operation of other programs
- Power supply: Device that powers the internal components and allows the server to be on 24 hours a day.
- Hard drive: Component that stores the server's programs and information; its capacity is typically several terabytes.
- Processor: A tool that helps process data and programs; several are found within the server due to the large amount of information stored on the computer.
- RAM Memory: Storage system that temporarily stores information so that the computer can perform its functions; if this memory becomes full, the hard drive memory is used, which results in slower processes.
- CD or DVD reader: It allows playback of both CDs and DVDs.
- System boards: Keep the different server components connected.
Types of servers
Mail server
It allows you to manage email-related operations. It sends, receives, and stores information. It facilitates communication between users and makes data transmission more efficient.
Proxy Server
A device that acts as an intermediary between two systems, preventing direct connections between sender and receiver, thus acting as a security filter. The proxy server can be located within a firewall and is also available independently.
Web Server
Its function is to store a website's files (HTML, images, CSS stylesheets, and JavaScript documents) so they can be displayed to users. When the browser requests a file stored on the web server, it sends the request via HTTP. Once the request reaches the server, the HTTP server sends the requested information.
Database server
Stores, manages, and retrieves data. It simplifies and streamlines the administration of stored data by allowing you to configure user access and import or export data.
Dedicated servers
It is a purchased or leased server where a company uses the entire server, having complete control over it. These are typically located in data centers where a single client contracts the service or acquires the equipment to have full access to all the necessary resources.
Image servers
Dedicated image servers where people can store their photos and images. They also allow importing, exporting, and even recovering lost images.
