A NIC operates at those two layers.
The X.25 standard specifies protocols at the Physical, Data Link, and Network Layers of the OSI Model.Broadband Cable functions at both the Physical, and Data Link Layers.ISDN functions at the Physical, Data Link, and Transport Layers.DSL, SONET, and T-Carriers function at the Physical Layer.Frame Relay, and ATM function at the Data Link Layer.
both models represent the actual system
Transmit (TX) and Recieve (RX). A network card is responsible for encoding data\decoding data. It resides in the OSI model as both Physical\Data Link layers and handles the physical connection to a network as well as the low level addressment through a MAC address.
According to Cisco Curriculum Semester 4 1.2.1.1 As described in relation to the OSI reference model, WAN operations focus primarily on Layer 1 and Layer 2. WAN access standards typically describe both Physical layer delivery methods and Data Link layer requirements, including physical addressing, flow control, and encapsulation.
The Stagecoach Bus Company operates in both areas.
That is a loaded question...it depends on what you mean by gateway. I proxy server can be a gateway so can a router. Typically, its gateway=router. check this chart out: http://www.geocities.com/SiliconValley/Monitor/3131/ne/osimodel.html I consider it on the Network layer. Let me know if this helps!

These protocols are higher level CAN bus protocols. They both use the CAN 2.0B standard for the physical and data link layer. Each protocol, however, has different standards for the higher layers in the OSI model, and thus the way in which data is transmitted and interpreted is unique to each.

The French Connection US is a women's and men's fashion clothing retailer which operates both in physical stores and online. They offer a wide selection of fashionable clothing for both men and women in a large variety of sizes.
The Earth has three compositional layers and five structural layers. Both layers have iron, magnesium, aluminum and silica.
They are both models, andthey both can be explained.
