A "host" in computing is a computer or device connected to a network that provides or requests services, while a "web host" is a company that provides hosting services by renting out space on a physical or virtual server to store a website's files, making it accessible on the internet. Essentially, a host is a device that participates in application-level functions on a network, and a web host is a specialized type of host that specifically provides the infrastructure for websites.

Host (general computing term)

A device on a network: A host is any computer or device on a network that can send or receive data, such as a user's personal computer or a server.

Provides or receives services: It functions as either a client or a server, or both, in user applications.

Distinct from network infrastructure: Unlike a router or switch, which are considered network nodes, a host is actively involved in application-level functions and has an IP address.

Web host (specific to web hosting)

A service provider: A web host is a company that provides the service of hosting websites.

Rents server space: When you use a web host, you are renting space on a physical or virtual server to store your website's files, data, and content.

Provides necessary resources: The web host is responsible for ensuring the server is running, secure, and has the resources (like storage and bandwidth) to make your website accessible to visitors.

Types of web hosting: Common types include shared hosting, VPS hosting, cloud hosting, and dedicated hosting, each offering different levels of resources and control.
