What are the two fundamental approaches to build a network core
What is packet switching and circuit switching?
Circuit switching and packet switching are the two different methods of switching that are used to connect the multiple communicating devices with one another. The key difference between circuit switching and packet switching is that packet switching is connectionless, whereas circuit switching is connection-oriented.
What is packet switching technique?
Packet switching is a connectionless network switching technique. Here, the message is divided and grouped into a number of units called packets that are individually routed from the source to the destination. There is no need to establish a dedicated circuit for communication.
How many users can be supported by circuit switching?
10 users
How many users can be supported by circuit switching? Only R/r = 10 users can be supported. This is because in circuit switching, the maximum traffic rate of r = 100 kbps (kilobits per second) has to be allocated on the link for every individual user.
In which switching each packet is treated independently?

What are the two approaches to packet switching?
There are two common packet switching methods in use:
- Datagram Packet Switching: Each packet is forwarded independently based on the destination address. …
- Virtual Circuit Packet Switching: A route is set up prior to packets being sent.
What are the three types of switching methods?
There are 3 common switching techniques:
- Circuit Switching.
- Packet Switching.
- Message Switching.
In which network two types of addressing are involved global and local?

What are the methods to move data through a network of links and switches?
What are the Methods to move data through a network of links and switches? Explanation: Packet switching and Circuit switching are two different types of switching methods used to connect the multiple communicating devices with one another.
Which network is made of a set of switches connected by physical links in which each link is divided into N channels?
circuit-switched network
A circuit-switched network is made of a set of switches connected by physical links, in which each link is divided into n channels.
Which layer links the network support layers and user support layers?
Which layer is used to link the network support layers and user support layers? Explanation: Physical, data link and network layers are network support layers and session, presentation and application layers are user support layers. The transport layer links these layers by segmenting and rearranging the data.
What is the access technique used by an LTE or LTE a network?
An LTE network employs the multiuser variant of the orthogonal frequency-division multiplexing (OFDM) modulation scheme, called orthogonal frequency-division multiple access (OFDMA), for its downlink signal.
How many types of major components are present in telephone network?
Major Components of Telephone Network: There are three major components of the telephone network: Local loops. Trunks. Switching Offices.
Which of the network layers directly connects the user to the network?
The network layer is layer 3 in the OSI model, and it is responsible for connections between different networks.
Which of the following layer is not a network support layer?
Discussion Forum
| Que. | Which of the following layer is not network support layer? |
|---|---|
| b. | Network Layers |
| c. | Data link Layer |
| d. | Physical Layer |
| Answer:Transport Layer |
What are the responsibilities of network layer?
Main responsibility of Network layer is to carry the data packets from the source to the destination without changing or using it. If the packets are too large for delivery, they are fragmented i.e., broken down into smaller packets.
What are the two main services provided by the network layer of the TCP IP model?
The two most important protocols in the Transport Layer are Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). TCP provides reliable data delivery service with end-to-end error detection and correction. UDP provides low-overhead, connectionless datagram delivery service.
Why is routing the responsibility of the network layer?
The network layer is responsible for routing, which is moving packets (the fundamental unit of data transport on modern computer networks) across the network using the most appropriate paths. It also addresses messages and translates logical addresses (i.e., IP addresses) into physical addresses (i.e., MAC addresses).
What are the different types of network layer protocols?
TCP/IP Protocol Architecture Model
| OSI Ref. Layer No. | OSI Layer Equivalent | TCP/IP Protocol Examples |
|---|---|---|
| 5,6,7 | Application, Session, Presentation | NFS, NIS+, DNS, telnet , ftp , rlogin , rsh , rcp , RIP, RDISC, SNMP, and others |
| 4 | Transport | TCP, UDP |
| 3 | Network | IP, ARP, ICMP |
| 2 | Data Link | PPP, IEEE 802.2 |
What are the two types of network relationship?
Generally there are two types of network connections: Peer-to-Peer and Network Shared environment.
Which two protocols operate at the transport layer of the TCP IP choose two?
Answers Explanation & Hints:
TCP and UDP are transport layer protocols.
What is the fundamental protocol that the Internet uses today?
What is the fundamental protocol that the Internet uses today? TCP/IP; The TCP/IP protocol is what allowed computers to share information outside their network, which stemmed the creation of the Internet as we know it today.
What are the two models of network architecture?
Two of the most widely used types of network architecture are peer-to-peer and client/server. Client/server architecture is also called ‘tiered’ because it uses multiple levels. This lesson will discuss each of these two types in more detail.
