IP carries data for a variety of different upper layer protocols. The internet layer provides an unreliable datagram transmission facility between hosts located on potentially different IP networks by forwarding the transport layer datagrams to an appropriate next-hop router for further relaying to its destination. With this functionality, the internet layer makes possible internetworking, the interworking of different IP networks, and it essentially establishes the Internet.
The Internet Protocol is the principal component of the internet layer, and it defines two addressing systems to identify network hosts' computers, and to locate them on the network.

It uses a bit IP address and is therefore capable of identifying approximately four billion hosts. This limitation was eliminated in by the standardization of Internet Protocol version 6 IPv6 which uses bit addresses. IPv6 production implementations emerged in approximately Transport layer[ edit ] The transport layer establishes basic data channels that applications use for task-specific data exchange.
The layer establishes host-to-host connectivity, meaning it provides end-to-end message transfer services that are independent of the structure of user data and the logistics of exchanging information for any particular specific purpose and independent of the underlying network.
The protocols in this layer may provide error control , segmentation , flow control , congestion control , and application addressing port numbers. End-to-end message transmission or connecting applications at the transport layer can be categorized as either connection-oriented , implemented in TCP, or connectionless , implemented in UDP.

For the purpose of providing process-specific transmission channels for applications, the layer establishes the concept of the network port. This is a numbered logical construct allocated specifically for each of the communication channels an application needs. For many types of services, these port numbers have been standardized so that client computers may address specific services of a server computer without the involvement of service announcements or directory services.
Because IP provides only a best effort delivery , some transport layer protocols offer reliability. For example, the TCP is a connection-oriented protocol that addresses numerous reliability issues in providing a reliable byte stream : data arrives in-order data has minimal error i. It is message-stream-oriented—not byte-stream-oriented like TCP—and provides multiple streams multiplexed over a single connection.
It also provides multi-homing support, in which a connection end can be represented by multiple IP addresses representing multiple physical interfaces , such that if one fails, the connection is not interrupted. It was developed initially for telephony applications to transport SS7 over IP , but can also be used for other applications. The User Datagram Protocol is a connectionless datagram protocol.
Like IP, it is a best effort, "unreliable" protocol. Reliability is addressed through error detection using a weak checksum algorithm.
Real-time Transport Protocol RTP is a datagram protocol that is designed for real-time data such as streaming audio and video.
By convention certain well known ports are associated with specific applications. Application layer[ edit ] The application layer includes the protocols used by most applications for providing user services or exchanging application data over the network connections established by the lower level protocols.
This may include some basic network support services such as protocols for routing and host configuration. Such functions are the realm of libraries and application programming interfaces. Application layer protocols generally treat the transport layer and lower protocols as black boxes which provide a stable network connection across which to communicate, although the applications are usually aware of key qualities of the transport layer connection such as the end point IP addresses and port numbers.
Application layer protocols are often associated with particular client-server applications, and common services have well-known port numbers reserved by the Internet Assigned Numbers Authority IANA.
Clients connecting to a service usually use ephemeral ports , i. The transport layer and lower-level layers are unconcerned with the specifics of application layer protocols. Routers and switches do not typically examine the encapsulated traffic, rather they just provide a conduit for it.
However, some firewall and bandwidth throttling applications must interpret application data. It is also sometimes necessary for network address translator NAT traversal to consider the application payload.
User protocols are used for actual user applications. It is a collection of software that manages computer hardware resources and offers common services for programs of the computer. The short term of the operating system is OS.
And, it is, an essential component of the system software in a computer system. The main purpose of an OS is to afford an environment in which a user can execute a program in an efficient or convenient manner. This article gives an overview of what is the Linux Operating System; the types of operating systems ; their architecture and features.
What is the Linux Operating System? Linux operating system is one of the popular versions of the UNIX operating system, which is designed to offer a free or low cost operating system for personal computer users. It gained the reputation as a fast performing and very efficient system. Since then, the resulting Linux Kernel has been marked by constant growth throughout the history.

In the year , Linux was introduced by a Finland student Linus Torvalds.However, it does reduce the aggregate network bandwidth used when reading data since a block is placed in only two unique racks rather than three. This is also the layer where packets may be selected to be sent over a virtual private network or other networking tunnel. If you want to download this book, click link in the last page 5. Currently, automatic restart and failover of the NameNode software to another machine is not supported.
This mechanism doesn't interfere with the way applications share the total bandwidth of the connection, and it doesn't reduce one application's latency at the expense of others.
