TCP/IP has 4 layers. OSI has 7 layers. TCP/IP more reliable than OSI OSI has strict boundaries; TCP/IP does not have very strict boundaries. TCP/IP follow a horizontal approach. OSI follows a vertical approach. In the application layer‚ TCP/IP uses both session and presentation layer. OSI uses different session and presentation layers. TCP/IP developed protocols then model. OSI developed model then protocol. TCP/IP offers support for connectionless communication within the network layer. In the network

scientists and DKK Scharfenstein resulted in the birth of ’Greenfreeze’ technology for domestic refrigeration. Greenfreeze refrigerators use hydrocarbons for both the blowing of the insulation foam and the refrigerant and they are entirely free of ozone destroying and global warming chemicals. When DKK Scharfenstein announced their intention to mass produce "Greenfreeze"‚ Greenpeace successfully campaigned to gather tens of thousands of pre-orders for the yet-to-be-produced new refrigerator from

The OSI model is a protocol stack where the lower layers deal primarily with

a. Flow control It is the process of managing the rate of data transmission between two nodes to prevent a fast sender from outrunning a slow receiver. It provides a mechanism for the receiver to control the transmission speed‚ so that the receiving node is not overwhelmed with data from transmitting node. Flow control should be distinguished from congestion control‚ which is used for controlling the flow of data when congestion has actually occurred. Error control It is the process of detecting

original. The design of TCP was comprehensively predisposed by what has come to be known as the "end-to-end argument". As per it relating to the Internet‚ the end-to-end argument says that by putting excessive intelligence in physical and link layers to handle error control‚ encryption or flow control you unnecessarily complicate the system. This is due to these tasks will usually need to be done at the endpoints nevertheless. The outcome of an end-to-end network at that point‚ is to offer marginal

architecture into seven distinct layers: the Application‚ Presentation‚ Session‚ Transport‚ Network‚ Data-Link‚ and Physical Layers. As a result it is frequently referred to as the OSI Seven Layer Model. A layer is a collection of theoretically similar functions that provide services to the layer directly above it and obtains service from the layer beneath it. On each single layer an instance provides services to the instances at the layer above and requests service from the layer beneath. An example of this
