Network Layer The network layer has two main functions. One is breaking up segments into network packets, and reassembling the packets on the receiving end. The other is routing packets by discovering the best path across a physical network.

What are three main functions of network layer?
Network Layer Services- Packetizing, Routing and Forwarding. Network layer is the third layer in the OSI model of computer networks. It's main function is to transfer network packets from the source to the destination. It is involved both at the source host and the destination host.
What are the four basic functions of the network layer?
The network layer defines communication over the network through four basic processes which are addressing, routing, encapsulation and decapsulation. These concepts are vital in understanding routing.
Which two functions are primary functions of a router?
The main purpose of a router is to connect multiple networks and forward packets destined either for directly attached networks or more remote networks.
What are the functions of Nvram?
Non-Volatile Random Access Memory (NVRAM) is a category of Random Access Memory (RAM) that retains stored data even if the power is switched off. NVRAM uses a tiny 24-pin dual inline package (DIP) integrated circuit chip, which helps it to gain the power required to function from the CMOS battery on the motherboard.
Which two functions are performed at the LLC sublayer?
The Logical Link Control (LLC) sublayer provides the logic for the data link; thus it controls the synchronization, flow control, and error-checking functions of the data link layer.
Which of the following is a function of a router?
Routers provide packet switching, packet filtering, internetwork communication, and path selection.
What is function of routing?
Routing is the act of finding a path to a destination and moving data across this path from source to destination. The routing process uses network routing tables, protocols, and algorithms to determine the most efficient path for forwarding the IP packet.
What are the function of routing in manufacturing?
The routing decides the path and sequence of operations to be performed on the job from one machine to another. The purpose of routing is to establish the optimum sequence of operations so that the manufacture of the finished item is performed at the lowest cost and the fastest time.
What is the difference between flash and NVRAM?
Flash is erasable and reprogrammable ROM. Flash memory content is retained by the router on power-down or reload. ... RAM contents are lost when the router is powered down or reloaded. NVRAM is non-volatile RAM.
Does NVRAM need a battery?
Stands for "Non-Volatile Random Access Memory." NVRAM is a type of RAM that retains data after the host device's power is turned off. ... Therefore, EEPROM does not need a battery or other power source to retain data.
What is stored in a router's NVRAM memory?
NVRAM: Non-volatile Random Access Memory: the start-up configuration is stored in this memory component. When a router is booted the IOS (Internetwork Operating System) reads this memory and gets the configuration file. This memory can be erased if required. ... This memory stores the IOS in a compressed form.
What is the function of the Logical Link Control LLC sublayer?
Logical Link Control (LLC) is a sublayer that generally provides the logic for the data link as it controls the synchronization, multiplexing, flow control, and even error-checking functions of DLL (Data Link Layer).
What is the role of MAC layer?
he medium access control (MAC) is a sublayer of the data link layer of the open system interconnections (OSI) reference model for data transmission. It is responsible for flow control and multiplexing for transmission medium. It controls the transmission of data packets via remotely shared channels.
