Can anyone explain the difference between a 512KB and a 1M network

The 512k and 1m you mentioned actually refer to bits, not bytes. A bit is the smallest unit of memory, also known as a "bit", and it has only two states, one and one for 0. We call 8 consecutive bits a byte.

The bit rate is the rate at which the data is transferred. Their relationship: kilobit, that is, kbit, it is not the same as kb, kb is the meaning of kilobyte, and 1byte=8bit kilobit rate is written:

kbit s, which means that 1000 bits of data are transmitted per second, converted into bytes, that is, 1000 divided by 8 is 125 bytes, that is, 1kbit s = 125kb, so the theoretical value of your 1m bandwidth should be: 128kb s, but because there will be losses on the way from the telecommunications bureau to your home, the actual value will be different. In addition, I will give you a relevant concept, I hope it will be beneficial to you.

Broadband: refers to the same transmission medium, the use of special technology or equipment, can use different channels for multiple (parallel) transmission, and the rate is more than 256kbps, as for how much speed is counted as broadband, there is no international standard at present, some people say that greater than 56k is broadband, some people say that more than 1mbps is considered broadband, here we consider it as 256k according to the convention and the amount of data in the network. Therefore, compared with traditional Internet access technology, the biggest advantage of broadband access technology is that its bandwidth rate is far more than 56kbps dial-up.

Bandwidth: Bandwidth is the maximum data traffic per unit of time, which can also be said to be the maximum number of binary bits that can be transmitted per unit of time. The 1M bandwidth refers to 1Mbps = 1 megabits per second For example, the ordinary ** line is theoretically 8M bandwidth, and the 2M line and 155M line are all about the bandwidth, and the bandwidth is related to the physical transmission**.

**There is 100kb of network speed of 1m 100kb * 8 = 800kb 800kb is obviously greater than 512kb **The relationship between speed and network speed is 8 times the relationship, do the math yourself.

Answer: C

c. Hidden collapse analysis] Stove Feng This question assesses the content of the computer's storage capacity. 1kb = 10248, so 512kb = 512 10248.

Your home is 1m ADSL, in fact, the so-called 1M ADSL means that your downlink speed is 1m, and the uplink speed is still 515KThis is a little trick that Netcom or Telecom played on us.

The speed of ADSL is limited after all, and the speed of 300K S can only be achieved by optical fiber, which is a dedicated line, and ADSL is still limited to the first line.

In addition, the display of 300k s that you start directly with IE is not actually your real speed, but the maximum speed supported by the address, and you start to display it, and then due to the limitation of bandwidth, it can only be maintained at a speed of tens of kb.

PS: ADSL is an unequal speed connection, in the vernacular, the uplink and downlink rates are not equal.

In addition to the upstream traffic and the downstream traffic, there are other control flows in addition to the data flow, and that's it.

2 megabytes of network speed is equal to 2048kbps, and the specific calculation method is as follows:

1kb=1024b

1mb=1024kb

2mb=2048kb

The burst rate will be higher.

It is 4m width.

4m broadband speed, generally without running other broadband resources, the theoretical 4m broadband network speed full speed** can theoretically reach up to 512k s, but in fact, we see that the **speed is less than 512k s, and it can generally reach about 400k, which is normal.

It's good for Netcom to reach this speed...

The key is that the test you use is **yes**. His 4m

It is only within the range of Netcom.

Bandwidth. It cannot be understood as the bandwidth of access to the large network.

A trillion. 128kb per second

Two megabytes per second at 256kb

Three trillion. Four trillion 512kb

This data is the fastest speed on the Internet.
