For example, consider a situation where Bob is sending data to Carol. Bob's socket layer has less than a complete packet's worth of data remaining to send. Per Nagle's algorithm, it will not be sent until he receives an ACK for the data that has already been sent.
If station A wants to send the acknowledgment, it first waits for a short period of time to see whether a data frame needs to be sent, then decides whether to send an ACK frame alone or attach a data frame with it. If station A wants to send just the data, then the previous acknowledgment field is sent along with the data.
Examples of the use of this prefix in names of Python applications or libraries include Pygame, a binding of Simple DirectMedia Layer to Python (commonly used to create games); PyQt and PyGTK, which bind Qt and GTK to Python respectively; and PyPy, a Python implementation originally written in Python.
Check the attachments. The image sent may have been sent as an attachment rather than an embedded image. If the image is sent as an attachment, you'll need to download it before you can view the image. Reset your web settings. Sometimes installing multiple browsers can result in your web settings getting changed.
Retransmission, essentially identical with automatic repeat request (ARQ), is the resending of packets which have been either damaged or lost. Retransmission is one of the basic mechanisms used by protocols operating over a packet switched computer network to provide reliable communication (such as that provided by a reliable byte stream, for example TCP).
Most email software and applications have an account settings menu where you'll need to update the IMAP or POP3 settings. When entering your account info, make sure you use your full email address, including @aol.com, and that the SSL encryption is enabled for incoming and outgoing mail.
Download all attachments in a single zip file, or download individual attachments. While this is often a seamless process, you should also be aware of how to troubleshoot common errors. Emails with attachments can be identified with Attachment icon in the message preview from the inbox. Download all attachments
Issues at the Network Layer Because DIME was defined at the data link layer, it was possible to encapsulate a DIME message in another DIME message. This would not help at all for compression purposes but was occasionally useful to bypass networking infrastructure such as routers at the network layer of the OS model, which would otherwise block ...
