What is a Gigabit adapter?

Gigabit Ethernet cards are network adapter cards with data traffic speeds of 1,000 megabits (about 1G) per unit area.

1000Mbit/s network card, also known as Gigabit Ethernet network card, is a network card that adapts from 10M/100M/1000M according to the network speed, and the maximum transmission speed can reach 1000Mbps/s.

Gigabit Ethernet network cards are mostly used in servers to provide high-speed connections between servers and switches, improving the responsiveness of network backbone systems.

Gigabit network adapter is a 32-bit PCI bus interface standard 10/100/1000Mbps/s network card, in line with 10Base-T, 100Base-TX, 1000Base-T network standards.

Support 32-bit PCI data bus, data transmission does not occupy CPU time, can directly exchange data with memory without CPU, thereby reducing the host load.

RJ-45 interface is adopted, and twisted pair is used to achieve convenient, fast, simple and reliable connection.

Due to the increase in data volume and price adjustment, many ordinary users have also begun to use Gigabit Ethernet network cards, and there is a popular trend.

Since the implementation of the Gigabit Ethernet physical layer is different from 10M/100M, the twisted pair used requires all four pairs of wires to be connected. Wire 5 is required to make cables.

What is a Gigabit Fiber Network Card?

1000Mbps optical network card, also known as Gigabit Ethernet optical network card, is a network card that adapts from 10M/100M/1000M according to the network speed, and the maximum transmission speed can reach 1000Mbps.

What is a USB Gigabit Wireless Adapter?

USB wireless adapter is a wireless network card, a built-in wireless WIFI chip, and through the USB interface transmission of the network card, connected to the computer USB interface, after the installation of the driver, the computer network card list will appear new wireless network card device. Internet access via USB wireless card.

USB wireless card is different from the commonly used ordinary network card, USB wireless card often uses low-radiation high-sensitivity Leiling 3070 chip, which is expensive, and is equipped with password cracking software. It is essentially a wireless network card core device, search network ability to be strong, equipped with BT5 hacking software, free Internet other people’s wireless network, as long as there is wired broadband nearby, there will basically be a wireless network.

The wireless network password setting for ordinary users is relatively simple, and the BT5 hacking software can be cracked with one click in a few minutes. Under normal circumstances, USB wireless network card surfers are not easy to be detected by real users if they are not downloaded with large traffic. In fact, as long as legitimate broadband users log in to the wireless router, they can check whether anyone is rubbing the network, and through MAC address filtering, restrictions, you can “kick” the other party away.

USB wireless adapter selection criteria

1. Wireless standard

Wireless LAN devices on the market mainly support IEEE 802.11g and IEEE 802.11n standards. Network cards that support the IEEE 802.11g+ standard have a maximum transmission rate of 108Mbps.

Network cards that support the IEEE 802.11n standard have a maximum transmission rate of 300Mbps, while network cards that support the IEEE 802.11b standard have a maximum speed of only 11Mbps; Network cards that support the IEEE 802.11g standard have a maximum speed of 54Mbps.

2. Interface

USB wireless card interface is mainly divided into USB 2.0, 1.1, 1.0 three, most of the USB interface wireless card has adopted USB2.0 interface. The USB2.0 interface provides 480Mbps of data communication bandwidth, while USB 1.0 is much slower.

3. Transmit power

As long as the wireless LAN equipment has a certain transmission power, the transmission power of the USB wireless network card is of course the higher the better, so that its transmission distance is farther, try to choose a wireless network card with higher transmission power when purchasing.

Especially with antenna technology, it can improve the signal coverage of the wireless card, so that users can have an efficient and stable wireless network.

4. Product appearance

USB wireless network card can be divided into two appearance forms: box type and U disk type. Box-type USB wireless cards come standard with a data extension cable, most of which are antennas exposed, these are designed to facilitate its placement on the desktop; The U disk type USB wireless network card is also equipped with a data extension cable as standard, and its USB interface can be directly inserted into the USB interface of the computer, because its antenna is built-in, so it is not inconvenient to adjust the direction of the antenna.
