Rules of Data Transmission

Page 2: Rules of data transmission

WData transmission is sending and receiving data via cables (e.g., telephone lines or fibre optics) or wireless relay systems. Because ordinary telephone circuits pass signals that fall within the frequency range of voice communication (about 300–3,500 hertz), the high frequencies associated with data transmission suffer a loss of amplitude and transmission speed. Data signals must therefore be translated into a format compatible with the signals used in telephone lines. Digital computers use a modem to transform outgoing digital electronic data; a similar system at the receiving end translates the incoming signal back to the original electronic data.

File Transfer Protocol (FTP) is a standard network protocol used to transfer files from one host to another host over a TCP-based network, such as the Internet.FTP is built on a client-server architecture and uses separate control and data connections between the client and the server. FTP users may authenticate themselves using a clear-text sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it.

The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web.Hypertext is structured text that uses logical links (hyperlinks) between nodes containing text. HTTP is the protocol to exchange or transfer hypertext.

MIDI (/ˈmɪdi/; short for Musical Instrument Digital Interface) is a technical standard that describes a protocol, digital interface and connectors and allows a wide variety of electronic musical instruments, computers and other related devices to connect and communicate with one another. A single MIDI link can carry up to sixteen channels of information, each of which can be routed to a separate device.MIDI carries event messages that specify notation, pitch and velocity, control signals for parameters such as volume, vibrato, audio panning, cues, and clock signals that set and synchronize tempo between multiple devices. These messages are sent to other devices where they control sound generation and other features. This data can also be recorded into a hard ware or software device called a sequencer, which can be used to edit the data and to play it back at a later time.

The Transmission Control Protocol (TCP) is one of the core protocols of the Internet protocol suite (IP), and is so common that the entire suite is often called TCP/IP. TCP provides reliable, ordered, error-checked delivery of a stream of octets between programs running on computers connected to a local area network, intranet or the public Internet. It resides at the transport layer.Web browsers use TCP when they connect to servers on the World Wide Web, and it is used to deliver email and transfer files from one location to another.

A protocol is a mutually agreed-upon format for doing something. With regard to computers, it most commonly refers a set of rules (i.e., a standard) that enables computers to connect and transmit data to one another; this is also called a communications protocol.The word protocol comes from the Greek word protocollon, meaning first glue. It referred to a leaf glued to a manuscript which described its contents.

-File Transfer Protocol (FTP)—Moves files between devices

• Simple Network-Management Protocol (SNMP)—Primarily reports anomalous network

conditions and sets network threshold values

• Telnet—Serves as a terminal emulation protocol

• X Windows—Serves as a distributed windowing and graphics system used for communication

between X terminals and UNIX workstations

• Network File System (NFS), External Data Representation (XDR), and Remote Procedure Call

(RPC)—Work together to enable transparent access to remote network resources

• Simple Mail Transfer Protocol (SMTP)—Provides electronic mail services

• Domain Name System (DNS)—Translates the names of network nodes into network addresses
