关键区别 - 提取与推
提取和推送是设置电子邮件客户端时将遇到的两个术语。设置电子邮件帐户时,您将有几个选项可供选择。这些选项包括获取和推动。您可能还具有手动选项。这两个术语确定从服务器发送电子邮件给客户端时的启动过程。这关键区别between fetch and push lies in the process of initiation;提取是由客户端启动的,而推动是由服务器启动的。获取是在推动成为现实之前检索电子邮件的主要模式。
Modern email accounts like Gmail come with the push option. This email feature can be utilized by at least one of our many email accounts we manage. With the advent of smartphones being able to send and receive emails, many people are confused about the two terms fetch and push.
什么是fetch?
使用Fetch,客户端将检查服务器以查看是否到达了电子邮件。如果找到一封或多封电子邮件,将将其下载到客户端设备。可以配置从几分钟到几个小时的间隔检查。因此,与推动相比,提取速度较慢,并且可能需要更长的时间才能响应。如果此间隔更长,则接收电子邮件会延迟。可以通过减少时间间隔来最小化此延迟。减少获取间隔的缺点是,无论是否已收到新邮件,它都可以为每个获取消耗更多的电池。每个获取也需要数据传输。此间隔可设置为每15分钟,30分钟,1小时或为手动值设置。在上述情况下,我们可以清楚地看到获取不是理想的选择,因为不会立即发送电子邮件。 This may not be good enough if you are receiving a lot of emails.
什么是推?
与推动,客户端设备不需要check the server on a regular basis to see if a mail has arrived. When an email arrives at the server, it will be automatically notified to the client and the delivery of the email will take place. As the delivery of the mail is done automatically in push, this is faster when compared with fetch. Push does not query the server in a regular manner as with fetch. The role of push is to update the server with its IP address so that the server will know how to contact the client easily.
推动是一种相对较新的方法IMAP与较旧的协议相比流行音乐。Older protocols like POP cannot use the push feature; it only comes with fetch capabilities. Email providers like Google and Yahoo are able to support major protocols. So they support both push and fetch option. Other email service providers need to be checked to see if they can support both the push and fetch retrieval features.
手动的
这re is also an option called Manual that will give you full control over the data that you receive. The message will appear as soon as you open mail, refresh the screen for viewing the mailbox or messages.
What is the difference between Fetch and Push?
定义
拿来:使用Fetch,您必须检查服务器以查看是否到达了电子邮件。
Push:电子邮件将在您的收件箱中嗡嗡作响,就像SMS或MMS一样。
引发
拿来:获取由客户启动
Push:推动由服务器启动
Speed
拿来:由于客户端必须定期检查服务器,因此获取相对较慢。
Push:推动相对更快,因为服务器将自动将邮件自动转发给客户端。
Power Consumption
拿来:当检查服务器的定期时间间隔内检查服务器时,获取将消耗更多的功率。
Push:随着发送电子邮件的过程自动完成,推动将消耗更少的功率。
功耗可能会有所不同,因为推动需要保持恒定的Internet连接才能自动接收电子邮件。这也将消耗客户端设备的功率。
支持
拿来:所有协议都支持获取
Push:所有协议都不支持推动。
提取与推送摘要
Push:服务器收到邮件后,它将被推到客户端设备上。
拿来:检查服务器以查看消息是否定期到达。进行此次检查时,将在客户端设备上下载消息。
手动的:打开邮件应用程序时检查邮件。
