Best Answer

G-bits per second is a digital communication baud rate. Gigahertz is a frequency of one billion cycles per second.

A:

A gigabit per second is a measurement of data transmission speed. Hard drives are measured by the rate they can transmit data in GB/S's.

Gigahertz on the other hand defines the clock speed of a processor which is a frequency measured in 1 billion hertz.

What is Google Fiber?

Google Fiber is a high speed broadband internet service. Speeds on their service range from 1 Gbit-5 Gbit/second, which is higher than current broadband services in the US. It is available at a handful of cities, but Google is eyeing expansion to several major cities.

What is the difference between wireless routers one with a GBit switch and one with a 10 to 100 switch in laymans terms please?

A gigabit switch allows other devices on your network to send and receive information at gigabit speed. A 10/100 switch is much much slower - allowing other devices on the network to communciate at a maximum rate of 100 megabits per second (versus a billion per second with gigabit). Of course, to get the higher speed, all of the computers on the network must also be capable of running at that speed. Otherwise you might be paying for something you aren't using.

Which unit of measurement is used to indicate the hard drive speed?

Depends: are you talking about the hard drive's spin speed, or the speed of data transfer? The first would be "rpm", meaning "rotation per second", while the second is measured in Mbit/s or Gbit/s, I seriously hope you're familiar with the notion of Mbit and Gbit (in the '90s MB and GB, megabyte and gigabyte were used mainly everywhere, which were replaced by megabits and gigabits when talking about data transfer, not static data, this is why I'm asking, no harm intended). The two units don't have a universal relationship between them, except for the fact, that when a hard drive spins faster, it is capable of a higher transfer speed.


What transmission speed does 100-Mbps or Fast Ethernet support?

Ethernet supports speeds as low as 10 Mbps and as high as 1 Gbps. There are new initiatives to support 10 Gbps in the near future.


Is 4g wireless internet really all the hubbub?

Well, the "4g" phones on the market today are faster than those marketed as 3G. However, it is really up to you to determine if the price difference between plans is worth the speed. It might be notable though that specified by the IMT-Advanced (International Mobile Telecommunications Advanced) 4G standards include speed requirements for 4G service at 100 Mbit/s for high mobility communication (such as from trains and cars) and 1 Gbit/s for low mobility communication (such as pedestrians and stationary users). Phones currently marketed as 4G are no where even close to these speeds. So realistically, the name 4G is more of a marketing ploy, and is more correctly defined as a quicker 3G.


What type of switch and over what type of cabling are workstation connections funneled into in a hierarchical star network?

You can create a hierarchial network using pretty much any type of networking equipment. No special equipment is required or needed, although if you are building a massive network, do consider at least Gbit interfaces and thus CAT6 cables.
