transport
layered model architecture is tcp/ip model .you can reference this model as layered model architecture protocol.
WAP is designed in a layered fashion so that it can be extensible,flexible, and scalable. As a result, the WAP protocol stack is divided into five layers:Application LayerWireless Application Environment (WAE). This layer is of most interest to content developers because it contains, among other things, device specifications and the content development programming languages, WML and WMLScript.Session LayerWireless Session Protocol (WSP). Unlike HTTP, WSP has been designed by the WAP Forum to provide fast connection suspension and reconnection.Transaction LayerWireless Transaction Protocol (WTP). The WTP runs on top of a datagram service such as User Datagram Protocol (UDP) and is part of the standard suite of TCP/IP protocols used to provide a simplified protocol suitable for low bandwidth wireless stations.Security LayerWireless Transport Layer Security (WTLS). WTLS incorporates security features that are based upon the established Transport Layer Security (TLS) protocol standard. It includes data integrity checks, privacy, service denial, and authentication services.Transport LayerWireless Datagram Protocol (WDP). The WDP allows WAP to be bearer-independent by adapting the transport layer of the underlying bearer. The WDP presents a consistent data format to the higher layers of the WAP protocol stack, thereby offering the advantage of bearer independence to application developers.Each of these layers provides a well-defined interface to the layer above it. This means that the internal workings of any layer are transparent or invisible to the layers above it. The layered architecture allows other applications and services to utilise the features provided by the WAP-stack as well. This makes it possible to use the WAP-stack for services and applications that currently are not specified by WAP.
The following antivirus programs have been voted the top 5 by the Lifehacker community; Lifehacker is probably the hub of all computer enthusiasts, so this information is extraordinarily reliable. * Avira AntiVir * Kaspersky Anti-Virus * Avast Antivirus * AVG Anti-Virus * NOD32 In addition to this, most major Antivirus company websites have a section on how to manually remove specific viruses, although you must have the name of the virus, and most viruses exact names are fairly long and include special characters.
In the TCP IP model, routers belong in layer 3. This is a common model used in setting up information technology systems.
What is the purpose of the TCP/IP Network Access layer
transport
The Network Layer in the TCP/IP model is responsible for routing data packets between different networks. It determines the best path for data to travel from the source to the destination through various interconnected networks. The Internet Protocol (IP) is the main protocol used at this layer to address and forward packets.
Network
TCP/IP because the osi model has seven layer but in tcp/ip only four layers and most important is that the tcp/ip model is reduce the function of osi model.
Protocol architecture or TCP/IP protocol architecture also referred to as the TCP/IP protocol suite is a simple fundamental underlying design which obeys a set of rules and conventions in which communication tasks are to be performed. The communication tasks of the protocol architecture are organized into five relatively independent layers: * Physical * Network Access Layer * Internet layer * Host-to-host, or transport layer * Application Layer In my research to this question it was interested to find out that there were some who consider the protocol architecture to be comprised of only four relative independent layers which are: * Network Access Layer * Internet layer * Host-to-host, or transport layer * Application Layer More information for each layer can be found at: http://www.microsoft.com/technet/prodtechnol/windows2000serv/reskit/cnet/cnbb_tcp_kscb.mspx?mfr=true http://www.unix.org.ua/orelly/networking/tcpip/ch01_03.htm
tcp/ip is good....
TCP and UDP are transport layer protocols; the OSI layer is layer 4 (transport)
IPsec is the standard method of encyption for TCP/IP
TCP operates at transport layer
TCP- Transfer control protocol. it control the transprotaion of the data. its established the connection between the hosts. its work on 4th layer. IP -IP mean internet protocol.its deal with the packets
