What is an upload?

In terms of the Internet, “downstream” data travels from the Internet to your computer. Each time you visit a web page, the content of that page must be downloaded to your PC to view the material, just as this page was downloaded. High Speed ​​Internet Service Providers (ISPs) pricing plans based on data download speed, as slow download speeds result in slow browsing. But you are also constantly uploading information or transferring data “upstream” from your computer to the Internet.

Musicians can upload their music to various websites.

An upload occurs whenever a request is sent from your browser to the Internet; for example, when clicking on a link. The upload, in this case, is a small packet of data that includes your Internet Protocol (IP) address, the page you are requesting, and a few other bits of information. The data packet or request traverses the Internet to reach the server that contains the requested information or web page. The return trip is download.

Because web page requests contain very small amounts of data, ISPs conserve bandwidth by making the upload speed of a typical Internet connection much slower than the download speed. The download speed may be 1,500 kilobits per second (kbps) to accommodate receiving bulky web pages, but the request for that page is only a few kilobytes that can be delivered quickly at 350 kbps back – the upstream rate.

You can think of this in terms of two tunnels, with the download tunnel being approximately four times longer than the upstream tunnel. In most cases, you won’t notice the slower upload speed until you try to upload a large file. why would you do that?

There are several situations online that require you to upload files. If you create a website, you will need to upload web pages and related content to the domain server, the computer that hosts the website. Text-based files will load quickly, but large images, music, or multimedia files will take a little longer. If you belong to a socializing site like FaceBook® or MySpace®, you may want to upload digital photos, MP3s or video clips to your profile. Maybe you want to make a movie of yourself playing an original song and upload it to YouTube®.

Torrenting, a social networking architecture that allows users all over the world to exchange files with each other, requires a 1:1 sharing ratio to avoid limited download speeds. For each file downloaded, the user must upload a file of equal size. If a user doesn’t know that their internet connection is much faster in one direction than the other, then using torrents highlights the point. A user who spends three hours downloading a file may have to leave the computer running for 12 hours or more to load the same amount of data.

Some companies with offsite offices that are linked to the Internet through a virtual private network (VPN) may require upload speeds that match download speeds. This would allow an employee in New York, for example, to upload a large file to an employee in Los Angeles in minutes instead of hours. This is called a synchronous connection, while most plans are asynchronous. Synchronous ISP plans are more expensive than asynchronous plans and therefore not as common.
