reasons, but it gets to technicial for this forum. Even in a 100mbps network, actual transfer speeds are usually around 40mbps.
This is an incorrect statement.
The reason reason you download at 150KB but your connection is rated at 1.5Mb is because your looking at two different transfer ratings. All internet
connections are rated in BITS (ex: 1.5Megabits or Mbps ) while file transfers are rated in KiloBytes(ex: 150KiloBytes or KBps).
For example. There are 8 BITS in a BYTE. At home, we have a 1.5Mbps (Megabit) connection to the internet via ADSL. Take that 1.5 Mbps and translate
it into real number form, which is 1500. Now divide that 1500 Bits by 8 to get a byte translation. You end up with a theoretical throughput of 187.5
KBps or KiloBytes per second. This is what file transfers are rated in. This is often how broadband companies snag customers who dont know their
technology well. They think they are buying 1.5 MegaByte Per second service, but its really only Megabits!
While you are correct about inernet traffic (and other forms such as noisey line, packet loss, bad routers btween client and server, etc etc) It is
not why a 1.5 Megabit connection transfers at 150KiloBytes. Thats actualy a good file transfer speed for a broadband connection as your only hitting
around 25-30 below a PERFECT connection (Which is rare or unseen in any broadband situation since most 1.5Megabit connections actualy run around
Remember not to confuse Mbps with MBps or Kbps with KBps. They are two different worlds.
The standard for a while now has been 100Mbps (pronounced mips) transmission, which means 100000000 bits per second.
Also in the article i noticed he said the connection term (mbps) translated to "mips". This is not correct. Mbps is an abbreviation, its pronounced
"Megabits per second" while Gbps is the same and pronounced "Gigabits per second" Mips is a term used to calculate the speed in which a CPU can
n : (computer science) a unit for measuring the execution speed of a computer's CPU (but not the whole system); "4 MIPS is 4,000,000 instructions
per second" [syn: MIPS, million instructions per second]
