The Network Access Layer is the lowest layer of the TCP/IP protocol hierarchy. The protocols in this layer provide the means for the system to deliver data to the other devices on a directly attached network. It defines how to use the network to transmit an IP datagram. Unlike higher-level protocols, Network Access Layer protocols must know the details of the underlying network (its packet structure, addressing, etc.) to correctly format the data being transmitted to comply with the network constraints. The TCP/IP Network Access Layer can encompass the functions of all three lower layers of the OSI reference Model (Network, Data Link, and Physical).

Digestion and absorption of food are major functions of gastrodermis .
The OSI layers are : 1) Layer 1 - physical physical layer - it content electrical and physical specification for devices this layer carries optical or electrical signal from end to end network devices 2) Layer 2 - data link data link layer - it mound over physical layer to control signals transmission end to end without any loss this layer divided into two parts MAC - media access control LLC - logical link control MAC - it use to access network with out any collusion LLC - it use to transmit frames without any loss it major work is convert packet into frames it find destination by help of MAC address 3) Layer 3 - network network link layer - it header layer of network part because it will route packets by help of destination ip address (even though destination is present in other network ) and next node MAC address two major task this layer will follow up 1. collect informations of all available routes 2. after that to find best routes of them this above two things can be achieve by network layer by the of following protocols EIGRP,RIP, OSPF etc., 4) Layer 4 - transport 5) Layer 5 - session 6) Layer 6 - presentation 7) Layer 7 - application
A discontiguous network comprises a major net that separates another major net
The major function of the serosa is to provide a protective layer around organs in the abdominal cavity. It also helps to reduce friction between organs as they move against each other during digestion and other bodily functions.

What is the Network mask of IP 185.185.0.0 in dotted decimal? How do I calculate First host of the major network IP address? What would be my last host of the major network?"
Discontiguous Networks.

The crust, the layer we live on.
The four major parts of Earth are the crust (outer layer), mantle (middle layer), outer core (liquid layer), and inner core (solid layer).
