Computer Networks Pdf Application layer 2 5 p2p architecture • no always on server • arbitrary end systems directly communicate • peers request service from other peers, provide service in return to other peers – self scalability – new peers bring new service capacity, as well as new service demands • peers are intermittently connected and change ip addresses – complex management peer peer application layer 2 6 processes communicating process: program running within a host • within same host, two processes communicate using inter process communication (defined by os) • processes in different hosts communicate by exchanging messages client process: process that initiates communication server process: process that waits to be contacted aside: applications with p2p architectures have client processes & server processes clients, servers application layer 2 7 sockets • process sends receives messages to from its socket • socket analogous to door – sending process shoves message out door – sending process relies on transport infrastructure on other side of door to deliver message to socket at receiving process internet controlled by os controlled by app developer transport application physical link network process transport application physical link network process socket application layer 2 10 what transport service does an app need? data integrity • some apps (e.g., file transfer, web transactions) require 100% reliable data transfer • other apps (e.g., audio) can tolerate some loss timing • some apps (e.g., internet telephony, interactive games) require low delay to be “effective” throughput some apps (e.g., multimedia) require minimum amount of throughput to be “effective” other apps (“elastic apps”) make use of whatever throughput they get security encryption, data integrity, …. Personal computers are powerful tools that can process and manipulate large amounts of data quickly, but they do not allow users to share that data efficiently. before networks, users needed either to print out documents or copy 2 document files to a disk for others to edit or use them.
Major Classification Of Computer Networks Computer Networks Assignment In this course, you'll learn about the devices and media that make up the information network. you'll also learn about the importance of addressing and naming schemes in network communications. The document discusses network models and the osi model. it describes the seven layers of the osi model which are physical, data link, network, transport, session, presentation, and application layers. Networking is the term describes the processes involved in designing, implementing, upgrading, managing and working with networking and network technology. experts agree that networking is worth your time and effort and can help you to get ahead in the professional world. Enterprise computer networks consist of multiple network devices, servers, and connections. it is important to manage who has access to which resource, so that only authorized users can manage and make changes to these elements and configurations in the network.
