Short Answer Type Questions

Question. What is protocol independence?
Answer : All protocol share the same physical cabling which allows multiple protocols to peacefully coexist over the network. So common hardware can be used for a variety of protocols. This concept is known as protocol independence.

Question. explain telnet with its advantage.
Answer : telnet is a network protocol which allows the user to get connected to other hosts via remote login. telnet remote login is widely sed for file sharing.
One can then easily browse the host’s machine and can download or upload files from/to the host. It works on a standard port number – 23. telnet allows the user to get access to any remote host machine through remote login.
Using this protocol, one can access the remote computer as his/her own computer.
The main advantage of using telnet is that the user can make changes related to system which is not possible in any other method. All type of resourcescan be shared.

Question. what is the difference between TCP and IP?
Answer : TCP breaks the data into packets that the network can handle while IP handles the address part and makes sure the packet reaches to the right destination.

Question. differentiate between SFTP and SCP.
Answer : the basic difference between SFTP and SCP is SFTP works on interactive mode while SCP works on non-interactive mode. Using SFTP, the user can access remote file system i.e., creating, deleting and listing files whereas, SCP is used only for transferring file.

Question. what are the differences between POP3 and IMAP Mail server?
Answer : IMAP is a standard protocol for accessing e-mail from a local server. A simpler e-mail protocol is post office protocol version 3 (POP3) which download mail to the computer and does not maintain the mail on the server.
In IMAP, e-mails are stored on the server, while in POP3, the messages are transferred to the client’s computer when they are read.

Question. differentiate between SSH and telnet.
Answer : SSH offers security mechanisms that protect the users against anyone with malicious intent while telnet has no security measures.
SSH uses encryptions to make it harder for the other person to sniff the password and other relevant information while in telnet, the data is encrypted in plain text, including passwords and can be easily sniffed by others.
SSH uses public key to authenticate the source of the data while telnet does not use any authentication.
SSH adds a bit more overhead to the bandwidth compared to telnet.

Question. what is SSH?
Answer : the secure shell (SSH) is protocol for secure remote login from one computer to another. It allows using several alternative options for strong authentication, and protects the communications, security and integrity with strong encryption.

Question. enlist the difference between FTP and TELNET.
Answer : (write in table)
TELNET stands for TELecommunication NETwork. FTP stands for file transfer protocol.
TELNET is also used for chat operation. FTP is used for downloading the files.
The port number in which FTP is work is 20 and 21.
TELNET uses only one connection.
FTP establish tow connections, one is for control command and another is for data transfer.
Remote login is necessary in TELNET.
Remote login does not necessary in FTP.
In does not provide high security, it provides only general security. It provides high security than TELNET.
It is used for transferring the files from one system to another system.
It is a connection oriented protocol.
It is also a connection oriented protocol.

Question. what is SCP?
Answer : SCP stands for secure copy protocol, which means the user can copy files across SSH connection.
That connection will be securely encrypted. It is a very secure way to copy files between computers.

Question. what is FTP?
Answer : file transfer protocol (FTP) is a standard internet protocol for transmitting files between computers on the internet. FTP is commonly used to transfer web page files from their creator to the computer that acts as their server for everyone on the internet. It is also commonly used to download programs and other files to your computer from other servers.

Question. What is ICMP?
Answer : ICMP is internet control message protocol, a network layer protocol used by hosts and gateways to send notifications of packets to the sender. If uses echo test whether a destination is reachable. It also handles control and error messages.

Question. what is a network protocol?
Answer : a network protocol is a set of rules for communication among networked devise. Protocol generally include rules of how and when a device can send or receive the data, how is the send data packaged, and how it reached its destination.

Question. what is the difference between HTTP and HTTPS?
Answer : write any two difference:

Question. what is PPP?
Answer : PPP (point to point protocol) comes into play when we establish a connection to our ISP (internet service provider) via a modem and we make up tow points on the network hence the protocol that is used to get things happening between the two of us is the point to point protocol or the PPP.

Question. write a short note on TCP/IP.
Answer : TCP/IP stands for transmission control protocol/internet protocol.
TCP/IP is a set of rules (protocols) governing communications among all computers on the internet.
More specifically, TCP/IP dictates how information should be packaged (turned into bundles of information called packets), sent, and received, as well as how to get to its destination. TCP/IP is a combination of two separate protocols. TCP (transmission control protocol) and IP (internet Protocol).
The internet protocol standard dictates the logistics of packets sent out over networks, it tells packets where to go and how to get there.
The transmission control protocol is responsible for ensuring the reliable transmission for ensuring the reliable transmission of data across internet-connected networks. TCP checks packets for errors and submits requests for re. transmissions If any are found.
