When we are lazy, we will say that the network bandwidth is 10 MB. Do not assume that the maximum download traffic can reach 10 MB of files downloaded per second. It is actually 10/8 = 1.25 MB. The reason is that the bandwidth unit is different from the hard disk unit.
Misunderstanding: whether KB is equal to KB
I often encounter such a problem. If we clearly apply for a MB bandwidth optical fiber, but when I download software from a local website, the download speed can only reach 10 MB, th

network drive to your own virtual physical drive. What's more, if your connected host has been connected to a LAN, then you can access all online resources through the host. In addition, while accessing the host, it does not affect the normal operation of the host, which is especially beneficial to users of the laptop.
When there are more than two computers (PCs), you need to use the NIC, network cable, and hub (HU.
If there is no Nic in the LAN, it is like a river without bridges on both sides
widely used technologies in the computer network field, most switch products now support this technology, such as 3ComSuperStack3Switch4900 and the above mentioned switch. When purchasing a gigabit network card, pay attention to whether the storage forwarding mode is supported to ensure the normal operation of the network. Direct-through forwarding means that the switch has started to forward data before it receives the entire frame, which can reduce the latency and is rarely used at present.

In computer networks or network operators, in general, the unit of broadband rate is expressed in bps (or b/s), and bps represents bits per second, which represents the number of bits per second, and is the abbreviation for bit second. In practice, the 1M bandwidth means 1Mbps (Mbps is megabits per secon

In mobile phone technology, the second-generation protocol uses digital coding, which includes GSM, D-amps (TDMA) and CDMA. 2G Network is currently being used worldwide. These protocols support high-bit-rate voice and limited data-communication capabilities. They provide a variety of ancillary services, such as data, faxes, and SMS. Most 2G protocols provide different levels of encryption.
