3 things aiding ozone layer deteoration are:.1. Global Warming. 2. CFC's. 3. Deforestation by humans.
it goes through and harms the layer,plus it damages staues or things with same objects
Layer 2
layer shading is the same as layer colouring
TCP operates at Layer 4 which is Transport of the OSI Model!
There are no bad things about the ozone. It is a layer which protects us.
The IP address and the subnet mask are required in layer 3 for routing purposes.
Only the Network Layer (Layer 3) portion of the datagram is used by the Network Layer (Layer 3) portion of the TCP/IP Model. The network portion of the datagram includes IP Addressing information, and things such as TTL (Time to Live), and Datagram Priority markings.
that layer
Network layer or layer 3
The temperature of ozone layer is same as stratosphere. It is because ozone layer is in stratosphere.
I believe there is no such thing as switching "from layer 3 to layer 2". Switching is either done within layer 3, or within layer 2.
