A modem (modulator-demodulator) is a network hardware device that modulates one or more carrier wave signals to encode digital information for transmission and demodulates signals to decode the transmitted information.

The goal is attempting to produce a signal that can be transmitted easily and decoded to reproduce the original digital data.

Modems can be used with any means of transmitting analog signals, from light emitting diodes to radio.

A common type of modem is one that turns the digital data of a computer into modulated electrical signal for transmission over telephone lines and demodulated by another modem at the receiver side to recover the digital data.

Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks.

In operation since before 1985, NTP is one of the oldest Internet protocols in current use.

NTP was designed by David L.

Mills of the University of Delaware.

In computing, a server is a computer program or a device that provides functionality for other programs or devices, called "clients".

This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or devices.

Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client.

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.

Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.

A client is a piece of computer hardware or software that accesses a service made available by a server.

The server is often (but not always) on another computer system, in which case the client accesses the service by way of a network.

The term applies to the role that programs or devices play in the client–server model.

A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically.

The ability of computers to follow a sequence of operations, called a program, make computers very applicable to a wide range of tasks.

Such computers are used as control systems for a very wide variety of industrial and consumer devices.

This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer assisted design, but also in general purpose devices like personal computers and mobile devices such as smartphones.

The Internet is run on computers and it connects millions of other computers.
