DHCP
The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on Internet Protocol (IP) networks for automatically assigning IP addresses and other communication parameters to devices connected to the network using a client–server architecture. The technology eliminates the need for individually configuring network devices manually, and consists of two network components, a centrally installed network DHCP server and client instances of the protocol stack on each computer or device. When connected to the network, and periodically thereafter, a client requests a set of parameters from the server using DHCP. DHCP can be implemented on networks ranging in size from residential networks to large campus networks and regional ISP networks. Many routers and residential gateways have DHCP server capability. Most residential network routers receive a unique IP address within the ISP network. Within a local network, a DHCP server assigns a local IP addres ...

Operating System
An operating system (OS) is system software that manages computer hardware and software resources, and provides common daemon (computing), services for computer programs. Time-sharing operating systems scheduler (computing), schedule tasks for efficient use of the system and may also include accounting software for cost allocation of Scheduling (computing), processor time, mass storage, peripherals, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computerfrom cellular phones and video game consoles to web servers and supercomputers. , Android (operating system), Android is the most popular operating system with a 46% market share, followed ...

VLAN Management Policy Server
A VLAN Management Policy Server (VMPS) is a network switch that contains a mapping of device information to VLAN. The primary goal of VMPS is VLAN assignment for general network management purposes, but can also be used for providing security through segregating clients with an unknown MAC address A MAC address (short for medium access control address or media access control address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This use i ..., or through further extension of the protocol to provide login for Cisco ACLs. This last functionality is now deprecated by Cisco, in favour of 802.1X, and as the VMPS technology is Cisco proprietary, the VLAN assignment can now be carried out in the 802.1X framework. Client switches query the VMPS server using the VLAN Query Protocol, or VQP. Only Cisco produces hardware with VMPS client functionality, and is currently fully supported a ...

In classical geometry, a radius (: radii or radiuses) of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The radius of a regular polygon is the line segment or distance from its center to any of its vertices. The name comes from the Latin ''radius'', meaning ray but also the spoke of a chariot wheel. as a function of axial position ../nowiki>" Spherical coordinates In a spherical coordinate system, the radius describes the distance of a point from a fixed origin. Its position if further defined by the polar angle measured between the radial direction and a fixed zenith direction, and the azimuth angle, the angle between the orthogonal projection of the radial direction on a reference plane that passes through the origin and is orthogonal to the zenith, and a fixed reference direction in that plane.

Trivial File Transfer Protocol
The Trivial File Transfer Protocol (TFTP) is a simple Lockstep (computing), lockstep communication protocol for transmitting or receiving files in a client-server application. A primary use of TFTP is in the early stages of nodes booting on a local area network when the operating system or firmware images are stored on a file server. TFTP was first standardized in 1981 and updated in . Overview Due to its simple design, TFTP can be easily implemented by code with a small memory footprint. It is, therefore, the protocol of choice for the initial stages of any network booting strategy like Bootstrap Protocol, BOOTP, Preboot Execution Environment, PXE, Boot Service Discovery Protocol, BSDP, etc., when targeting from highly resourced computers to very low resourced Single-board computers (SBC) and System-on-a-chip, System on a Chip (SoC). It is also used to transfer firmware images and configuration files to network appliances like Router (computing), routers, Firewall (computing) ...

Dynamic DNS
Dynamic DNS (DDNS) is a method of automatically updating a name server in the Domain Name System (DNS), often in real time, with the active DDNS configuration of its configured hostnames, addresses or other information. The term is used to describe two different concepts. The first is "dynamic DNS updating" which refers to systems that are used to update traditional DNS records without manual editing. These mechanisms use TSIG to provide security. The second kind of dynamic DNS permits lightweight and immediate updates often using an update client, which do not use the standard for updating DNS records. These clients provide a persistent addressing method for devices that change their location, configuration or IP address frequently. Background In the initial stages of the Internet (ARPANET), addressing of hosts on the network was achieved by static translation tables that mapped hostnames to IP addresses. The tables were maintained manually in form of the host file. The Do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Preboot Execution Environment
In computing, the Preboot eXecution Environment (PXE; often pronounced as ''pixie''), often called PXE boot (''pixie boot''), is a specification describing a standardized client–server environment that boots a software assembly, retrieved from a network, on PXE-enabled clients. On the client side it requires only a PXE-capable network interface controller (NIC), and uses a small set of industry-standard network protocols such as Dynamic Host Configuration Protocol (DHCP) and Trivial File Transfer Protocol (TFTP). The concept behind the PXE originated in the early days of protocols like BOOTP/DHCP/TFTP, and it forms part of the Unified Extensible Firmware Interface (UEFI) standard. In modern data centers, PXE is the most frequent choice for operating system booting, installation and deployment. Overview Since the beginning of computer networks, there has been a persistent need for client systems which can boot appropriate software images, with appropriate configu ...

BOOTP
The Bootstrap Protocol (BOOTP) is a computer networking protocol used in Internet Protocol networks to automatically assign an IP address to network devices from a configuration server. The BOOTP was originally defined in published in 1985. While some parts of BOOTP have been effectively superseded by the Dynamic Host Configuration Protocol (DHCP), which adds the feature of leases, parts of BOOTP are used to provide service to the DHCP protocol. Some DHCP servers also provide the legacy BOOTP functionality. When a network-connected computer boots up, its IP stack broadcasts BOOTP network messages requesting an IP address assignment. A BOOTP configuration server replies to the request by assigning an IP address from a pool of addresses, which is preconfigured by an administrator. BOOTP is implemented using the User Datagram Protocol (UDP) for transport. Port number 67 is used by the server for receiving client requests, and port number 68 is used by the client for receiving serv ...
