Error code 426 happens when you're uploading or downloading to an FTP site and the transfer aborted. The error would say, 'Connection closed, transfer aborted.' It could mean that the connection was made in a passive mode: Your computer tried to connect to the server through a random port, but was blocked by the server's firewall. It could also mean that a firewall in your computer blocked the session. When you get this error, ensure that no firewall is blocking the connection.
Error Code 530
This error code means that FTP authentication was not successful. The combination of the username and password you've typed was incorrect, thus you were denied access to the FTP site. It could also mean a misconfiguration in IIS: You've allowed only anonymous access for FTP, but denied anonymous access for all IIS services. Verify that the username and password you used is correct or check if anonymous access is allowed by leaving the username and password options blank.
Error Code 550
This error is generated when you're downloading or uploading a file to the FTP site. When you're attempting to download a file and you get a 550 error, it means that the file you're downloading is no longer in the FTP directory. When you're uploading, it means that you do not have the right access to upload a file to the FTP site. Verifying that the file exists or that you have the proper access to put files in the FTP site eliminates this error.
Other 4xx Error Codes
Error codes that start in 4 mean that the error is temporary. Trying again at a later time and ensuring that there is enough disk space and that nothing is interfering with the connection will often resolve the error.421: The FTP service is not available at the moment. It can be because the maximum FTP connection is reached or you are not authorized to connect through FTP.425: You cannot open a connection. A firewall could be blocking the connection or the type of connection you're trying is not allowed. Try different methods of FTP connection such as having FTP software or connecting to FTP through HTTP.450: The file you're trying to access cannot be copied. Other users or programs may be using the file, causing it to lock. You can try again later to see if the file has been released.451: There was an error in the command typed for the FTP connection. Ensure that the commands you typed are correct.452: Not enough disk space exists in the hard drive that you're downloading or uploading the file. Cleaning up the hard drive resolves this issue.
Other 5xx Error Codes
Error codes that start in 5 mean that the error is permanent. Retrying will only result with the same error.500: A syntax error could mean that the command line is too long. Try either the FTP passive or active mode depending on the mode you're currently using.501: There was an error with the command you typed. You may have missed or mistyped some characters.503: The commands you typed were not in the proper sequence.504: There was an error in the parameter with the command. Make sure that the parameter you entered is valid for the command.532: You do not have the proper access to store files remotely.552: There's not enough space on the server that you're remotely saving the file. 553: The file you're uploading has invalid characters. Renaming the file resolves the issue.

The Advantages of ProtocolsIn Feburary 2016 22,
In Feburary 2016 22,
Transfer protocols move files and data from one location to another. Two computers in the operation are required: one is a transferring server and the other a receiving client. Several file transfer protocols include the following:FTP (file transfer protocol) allows the transfer of files. It establishes a connection to a remote client and transfers the files until completed, and then it disconnects. The connection can be in an internal network or over the Internet. Developed in 1971, this protocol served as one of the objectives for the development of the Internet.Xmodem is an alternative to the FTP protocol. It was popular with bulletin board services in the late 1970s because of its simplicity and ease of use.Kermit is a binary (0's and 1's) and text file transfer protocol designed in the early 1980s. For the transfer to occur a file conversion takes place to binary format before transmittal and then converted back afterwards. This allowed for file transfers over dissimilar systems.The advantage of these file transfer protocols is that they share information between different computer systems and different formats.

Transfer protocols allow files and data to move across networks.
E-mail Protocols
The Internet Message Access Protocol (IMAP) allows an e-mail client to access e-mail messages on a remote e-mail server.IMAP supports two modes of operation: online and offline. In online mode, e-mail clients using IMAP leave the e-mail messages on the server until the user purposely deletes them. In offline mode, the e-mail is downloaded and then deleted. This characteristic of the IMAP operation allows multiple clients to manage the same mailbox. The upshot is that the mail stays on the server automatically until deleted.POP (Post Office Protocol) is an alternate e-mail protocol that supports simple download and delete for access to remote mailboxes. Most POP clients have an option to leave e-mail on the server after download. However, e-mail clients typically follow this procedure. They connect to the server, retrieve their messages, store them on the user's local PC and then delete them from the server and disconnect. The upshot is, the mail is automatically deleted unless kept.The advantage of both of these protocols is enhanced e-mail management.

Software Developer Protocols
Software developers use protocols in their work. Platform-based database protocols like JDBC (Java DataBase Connectivity) or ADO (active x database objects) have a performance advantage. Also, flexibility and reuse are two main advantages of using a neutral platform protocol such as SOAP (Simple Object Access Protocol).This is a protocol specification that facilitates the exchange of structured information in web services.By using protocols, software architects and program developers can determine the opportunity cost of the project, that is, whether the development is going to be faster versus whether the program is going to be faster. These performance versus flexibility alternatives affect the coding decision, which impacts the way the program will run.The advantage of using these protocols is that they improve the performance of programs and provide flexibility in program design.
