How many kilobits are in a gigabit?
Depending on the convention used, 1 gigabit is either 1,048,576 kilobits, or it is 1,000,000 kilobits. The latter definition is the official one, and is used far more often.
Is a gigabit card faster than a megabyte card on Internet downloading if ISP comes in at 1.5 gigabytes?
The download from the ISP is not 1.5 gigabytes. It is 1.5 megabits per second or 1500 kilobits per second (kbps). A gigabit network interface card is used for local area network transfer of files at speeds of 1000 kbps not for transfer from the Internet. So gigabit NIC cards transfer data from computer to computer at these speeds and will not increase transfer data faster from the ISP to the computer at a faster…
If you want to upgrade your 100BaseT network so that it will run about 10 times the current speed what technology would you use?
You would want to move to a Gigabit network. This will require a switch capable of Gigabit speeds, network cabling capable of Gigabit speeds (Cat 5e for example), and a network interface on a computer that is also Gigabit rated. Most modern switches are Gigabit rated (even inexpensive soho switches).
"Kilobits per second" is a speed ... how fast data is moving from one place to another. "Megabytes" is an amount of data ... that you put in your wallet or on a CD. There's no way to convert a speed into an amount. If you had said "10 megabytes per second", then we'd answer: "10 megabytes per second is a speed equal to 80,000 kilobits per second".
Gigabit = 1,000,000,000 bps (bits per second) = 125,000,000 Bps (Bytes per second) = 125 MBps (Megabytes per second (10^3)) = 119.209... MiBps (Mebibytes per second (2^10)) 10 Gigabit = 10,000,000,000 bps (bits per second) = 1,250,000,000 Bps (Bytes per second) = 1.25 GBps (Gigabytes per second (10^3)) = 1.164... GiBps (Gibibytes per second (2^10)) The difference is obvious. 10 Gigabit = 10 x Gigabit or 10:1 Gigabit Ethernet is behind, it's less than 1/4…
The need for a 10 Gigabit Ethernet for home office depends on the actual use case: for simple data exchange between different machines there most probably no need for 10 Gigabit - but if there's a use-case for video-streaming or other multi-media related tasks then a 10 Gigabit Ethernet network might be indicated.
