A demarcation point is where one network ends and another begins. Explanation: Demarcation point can also be referred as demarc extension, or point of demarcation, or simply demarc.

What is the term for Place one network ends and another begins?
When discussing computer networking you’ll often hear the term demarcation point to describe where one network or system ends and another one begins.
What device determines the point where one local network ends and another local network begin?
A router is connected to two or more data lines from different IP networks. When a data packet comes in on one of the lines, the router reads the network address information in the packet header to determine the ultimate destination.
What is the process of taking a large network and splitting it up into many individual and smaller subnetworks called?
Subnetting. -> The process of taking a large network and splitting it up into many individual and smaller subnetworks or subnets; -> Address classes give us a way to break the total global IP space into discrete networks; – Example : To communicate with IP address – 9.100.
What is the process of taking a single IP datagram and splitting it up into several smaller datagrams called?
Fragmentation is the process of taking a single IP datagram and splitting it up into several smaller datagrams.
What does ARP stand for and what does it do?
Address Resolution Protocol
Address Resolution Protocol (ARP) is a protocol or procedure that connects an ever-changing Internet Protocol (IP) address to a fixed physical machine address, also known as a media access control (MAC) address, in a local-area network (LAN).
What is the purpose of ARP response?
ARP was defined in 1982 by RFC 826. ARP is a request-response or request-reply protocol in which one device sends a request to another device asking for some information, to which the other device will reply with the required information.
What device determines the point where one local network?
A router is a physical or virtual appliance that passes information between two or more packet-switched computer networks. A router inspects a given data packet’s destination Internet Protocol address (IP address), calculates the best way for it to reach its destination and then forwards it accordingly.
What is router vs switch?
Difference Chart between Switch and Router
| Switch | Router |
|---|---|
| It connects multiple networked devices in the network. | It connects multiple switches & their corresponding networks. |
| It works on the data link layer of the OSI model. | It works on the network layer of the OSI model. |
| It is used within a LAN. | It can be used in LAN or MAN. |
What is network topology class 8?
Network topology refers to the way a computer network is laid out, either physically or logically. It defines the way in which network devices are organized geometrically. In this topology all nodes are connected together to the parallel cable by drop lines and taps/T-connectors.
What is the process of taking a large network and splitting it up?
Subnetting; Subnetting is the process of taking a large network and splitting it up into many individual and smaller subnetworks, or subnets.
What is the process of taking a single IP datagram and splitting it up into several smaller datagrams called quizlet?
Fragmentation is the process of taking a single IP datagram and splitting it up into several smaller datagrams.
What is CIDR in network?
Classless Inter-Domain Routing (CIDR), also called supernetting, is a way to more flexibly allocate Internet Protocol (IP) addresses by creating unique and more granular identifiers for networks and individual devices.CIDR allows IP addresses to be variable and not bound by the size limitations of Classes A, B, and C.
Where in the network are packets fragmented?
Fragmentation is done by the network layer when the maximum size of datagram is greater than maximum size of data that can be held in a frame i.e., its Maximum Transmission Unit (MTU).
What is fragmentation and reassembly?
Fragmentation is the process of breaking a packet into smaller pieces so that they will fit into the frames of the underlying network. The receiving system reassembles the pieces into the original packets.RFC 791 (Internet Protocol, September 1981) describes fragmentation and reassembly.
Where does the Domain Name System DNS namespace begin?
The DNS namespace is hierarchical in structure, beginning with the root domain, which branches to top-level domains, then second-level domains, and so on to the individual host name.
What is the ARP process?
As we’ve learned before, the Address Resolution Protocol (ARP) is the process by which a known L3 address is mapped to an unknown L2 address.If a host is speaking to another host on the same IP network, the target for the ARP request is the other host’s IP address.
How does ARP work in network layer?
ARP broadcasts a request packet to all the machines on the LAN and asks if any of the machines are using that particular IP address. When a machine recognizes the IP address as its own, it sends a reply so ARP can update the cache for future reference and proceed with the communication.
What layer is ARP?
layer 2
Address Resolution Protocol (ARP) The Address Resolution Protocol is a layer 2 protocol used to map MAC addresses to IP addresses.
What is ARP example?
In the example above you see an example of an ARP table on a H1. As you can see there is only one entry, this computer has learned that the IP address 192.168. 1.2 has been mapped to the MAC address 00:0C:29:63:AF:D0. In this example we have two computers and you can see their IP address and MAC address.
Is ARP an IP protocol?
The address resolution protocol (arp) is a protocol used by the Internet Protocol (IP) [RFC826], specifically IPv4, to map IP network addresses to the hardware addresses used by a data link protocol. The protocol operates below the network layer as a part of the interface between the OSI network and OSI link layer.
