the architecture of computers made by OSI role in a network of computers to solve
OSI reference model (International for standardization
Organization) that is part of the architecture of computers made by OSI role in
a network of computers to solve design
problem in a computer with detecting components of computer components to the
device between vendors as well as provide some standardization that could be
used by many vendors in creating devices The. OSI consists of several
components or layers that can be used by the vendor. OSI is divided into two
parts: Upper layer (application layer) and the lower layer (data transport
layer).The upper layer is a collection of applications in a host of
applications that can be used by the user to communicate or connect with other
users in a network. The lower layer is the application data that is able to
send data or information messages to other users in a network. Application
layer is the interface or interfaces directly between user and computer.
application layer has the function to identify all the interfaces that
communicate from the communication partner, some application layer telnet.
Telnet is an application that can help users in accessing resource
a machine from a remote machine.FTP (file transfer protocol) is a program that
serves to transmit data or documents to many hosts in a network.DNS (domain
name system) is a computer or a machine domain address of the computer in the
form of a database.SMTP (simple mail transfer protocol) is a computer program
that manages all associated with the delivery of e-mails within computer
networks.
SNTP (Simple Network Management Protocol) is a computer program that
functions controlling all activities connected equipment devices in a computer
network.Presentation layer system is a computer application that provides multiple
data presentation, code is entered into the application layer and is able to
convert several different formats in the computer code as PITCT, JPEG MPEG etc.Session
layer system is a computer application program that is capable of coordinating
the activities of the course of communication between systems in a network and
be able process management, disconnection and control dialog between computers
in a computer network.
Transport layer system is a computer application that is
capable process upper layer of data ordering, shipping segment, and the
determination of the relationship between hosts and guarantee data delivery
processes appropriately and safely.Network layer is a computer application
system is capable of performing a routing mechanism and management system
through network against computer networks.The data link layer is a functioning
computer application system sends a message to another host in the form of
frames as well as the delivery in a computer network.Physical layer is a
computer application system that functions to send and receive bits. And serve
the needs of different user requirements across different physical systems
