  2. Server (computing) - Wikipedia

    en.wikipedia.org/wiki/Server_(computing)

    A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. [2] Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers. [3]

  3. M/D/1 queue - Wikipedia

    en.wikipedia.org/wiki/M/D/1_queue

    A single server serves entities one at a time from the front of the queue, according to a first-come, first-served discipline. When the service is complete the entity leaves the queue and the number of entities in the system reduces by one. The buffer is of infinite size, so there is no limit on the number of entities it can contain.

    A single server serves customers one at a time from the front of the queue, according to a first-come, first-served discipline. When the service is complete the customer leaves the queue and the number of customers in the system reduces by one. The buffer is of infinite size, so there is no limit on the number of customers it can contain.

  5. Queueing theory - Wikipedia

    en.wikipedia.org/wiki/Queueing_theory

    The main queueing models that can be used are the single-server waiting line system and the multiple-server waiting line system, which are discussed further below. These models can be further differentiated depending on whether service times are constant or undefined, the queue length is finite, the calling population is finite, etc. [ 5 ]

  6. Client–server model - Wikipedia

    en.wikipedia.org/wiki/Client–server_model

    In the client-server model, the server is often designed to operate as a centralized system that serves many clients. The computing power, memory and storage requirements of a server must be scaled appropriately to the expected workload. Load-balancing and failover systems are often employed to scale the server beyond a single physical machine ...

  7. Virtual hosting - Wikipedia

    en.wikipedia.org/wiki/Virtual_hosting

    Virtual hosting is a method for hosting multiple domain names (with separate handling of each name) on a single server (or pool of servers). [1] This allows one server to share its resources, such as memory and processor cycles, without requiring all services provided to use the same host name.

    • Emails are stored on a single device. • Sent messages are stored on a single device. • Emails can only be accessed from a single device. • If you want to keep messages on the server, make sure the setting "Keep email on server" is enabled or all messages are deleted from the server once downloaded to the app or software.

  9. Host (network) - Wikipedia

    en.wikipedia.org/wiki/Host_(network)

    A host is a node that participates in user applications, either as a server, client, or both. A server is a type of host that offers resources to the other hosts. Typically a server accepts connections from clients who request a service function. [4] Every network host is a node, but not every network node is a host.
