What is the difference between FTP and TFTP?
The Trivial File Transfer Protocol (TFTP) allows a local host to obtain files from a remote host but does not provide reliability or security. It uses the fundamental packet delivery services offered by UDP. The File Transfer Protocol (FTP) is the standard mechanism provided by TCP / IP for copying a file from one host to another. It uses the services offer by TCP and so is reliable and secure. It establishes two connections (virtual circuits) between the hosts, one for data transfer and another for control information.
Which protocol is used by FTP to transfer files over the Internet?
FTP uses TCP.Usage of Transport Layer protocol (tcp or udp) depends upon various applications.Such as FTP uses TCP, TFTP uses UDP.
What is the difference between a server and a web server?
== == The basic difference between a web server and an application server is Webserver can execute only web applications i,e servlets and JSPs and has only a single container known as Web container which is used to interpret/execute web applications Application server can execute Enterprise application, i,e (servlets, jsps, and EJBs) it is having two containers 1. Web Container(for interpreting/executing servlets and jsps) 2. EJB container(for executing EJBs). it can perform operations like load balancing , transaction demarcation etc etc
Difference between osi and tcpip model?
The main differences between the two models are as follows: 1.OSI is a reference model and TCP/IP is an implementation of OSI model.2.TCP/IP Protocols are considered to be standards around which the internethas developed.The OSI model however is a "generic, protocol-independent standard."3.TCP/IP combines the presentation and session layer issues into itsapplication layer.4.TCP/IP combines the OSI data link and physical layers into the networkaccess layer.5.TCP/IP appears to be a simpler model and this is mainly due to the fact thatit has fewer layers.6.TCP/IP is considered to be a more credible model- This is mainly due to the fact because TCP/IP protocols are the standards around which the internet was developed therefore it mainly gains creditability due to this reason. Where as in contrast networks are not usually built around the OSI model as it is merely used as a guidance tool. 7.The OSI model consists of 7 architectural layers whereas the TCP/IP onlyhas 4 layers. 8.The TCP/IP design generally favors decisions based on simplicity, efficiency and ease of implementation
Technology used in TFTP?
because TFTP is not capable of encrypting transmissions and FTP is.
What is port number tftp?
Port 69 and UDP are used for tftp transmissions.
What command and prompt used to load a save configuration file from the TFTP server?
RouterC#cpoy tftp running-config [ cpoy tftp run ]
What command and prompt are used to save a router configuration file to the TFTP server?
RouterC#copy running-config tftp [copy run tftp]
Your computer say tftp no reply from server?
Either from below is possible:Link to TFTP server is temporarily damaged.Link to TFTP server is permanently damaged.TFTP is shut down.
What does the command copy flash tftp accomplish?
it copies the ios FLASH to TFTP SERVER
Where will a router operating system image be copied after the copy flash tftp command is issued?
to TFTP
What is the tftp port number?
Port 69 and UDP are used for tftp transmissions.
Which command is used to upgrade an IOS on a Cisco router?
config tftp run
Does TFTP have a check sum to see whether packets are corrupted?
Nope, TFTP Relys on the UDP Checksums, and even those are optional, that's why its not used often exept for Bootloaders etc. Also there is no Encryption for tftp packets
From what location can a router load the Cisco IOS during the boot process?
TFTP server, Flash
Which Transport layer protocol does TFTP rely?
TFTP uses UDP - TFTP stands for Trivial FTP, and it is called trivial because it does not check to ensure delivery, it uses UDP which makes a best-effort delivery attempt
