Popular Choices Of Data Transmission ,[object Object],[object Object],[object Object],[object Object]

Universal Serial Bus (USB) This style of connection has been the industry standard for 13 years and serves as one of the most vital data transmission devices. USB offers internal power options which allow devices to utilize the power of the CPU to run the device. USB 2.0 transmits data at 480 Mbps. USB connections now face stiff competition from wireless connections, but as things stand, its effects are still being felt through out the world.

Uploads and Downloads Download refers to data transfer from the server to your computer and upload refers to data transfer from your computer to the server. It is of interest to know that upload and download occur on separate transmission channels (whether this be on a modem or on a special-purpose line). So, when you are sending (uploading) a document you are not losing any download bandwidth!
