Networklayer
layer 4 is responsible of error free data transmission
Five are free.
Transport layer
Data link layer transforms the physical layer and makes it appear error free. Data link layer is responsible for physical addressing. It has some other functions like error control, flow control and access control.
If you actually purchase 64 packets.Then you simply divide 64 by 4 and get 16 additional "free" packets of powder.Oops, now you have 16 more packets...And, divide that by 4 again to get 4 additional "free" packets.And, divide that by 4 again and you will get 1 additional "free" packet.So, you would have a total of 16+4+1 free packets = 21 free packets.And, you would have one token left over.Your total is 64 purchased packets, 21 free packets, and 85 total packets.
You simply divide 64 by 4 and that gives you 16 free packets.
No, they did not stop selling 2 quart packets of sugar free kool aid
An upper-layer packet is split into 10 frames, each of which has an 80 percent chance of arriving undamaged. If no error control is done by the data link protocol, how many times must the message be sent on average to get the entire thing through? An connection-oriented service (like TCP) does error checking and requests data to be resend. The packet has several options for error free transport. Connectionless service (think UDP) does not check for undamaged arival. It has a much smaller packet size and is also faster.
connectionless protocols
No. Gluten is also in barley, moult, and rye. Always look for Gluten Free on packets.
The Open Systems Interconnection model (OSI model) was a product of the Open Systems Interconnection effort at the International Organization for Standardization. It is a way of sub-dividing a communications system into smaller parts called layers. Similar communication functions are grouped into logical layers. A layer provides services to its upper layer while receiving services from the layer below. On each layer, an instance provides service to the instances at the layer above and requests service from the layer below.For example, a layer that provides error-free communications across a network provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that make up the contents of that path. Two instances at one layer are connected by a horizontal connection on that layer.
