Network cards

Network Card It is a type of network adapter. These adapters support Internet standard for network connections using high-speed cable. Network cards are sometimes referred to as network interface cards (NIC).

A few years ago, large ISA cards were the first personal computer, the user had to open the computer case to install a card.

New network cards, installed inside desktop computers use the PCI standard and are usually installed by the manufacturer.

Smaller PCMCIA Ethernet cards that resemble credit cards are readily available for laptops and other mobile computers. They are inserted into the slots on the side or front of the device.

There are also external network adapters USB Ethernet, though outwardly they are more like small boxes than cards. This is a handy alternative to PCI cards for desktop computers, they are also widely used in game consoles and other consumer devices that do not have PCMCIA slots.

Network cards can run on different network speeds, depending on the standard protocol they support. Older network cards were able to work only at 10 Mbps speed. Modern network cards all support 100 Mbps Fast Ethernet standard and a growing number are now also offer Gigabit Ethernet support at 1 Gbps speed.

Network Card It does not directly support Wi-Fi, but home network broadband routers contain the necessary technology to allow network devices to be connected via cables and use the Wi-Fi device through the router.

To find the range of the network cards that we can provide AliexpressEnough to move into the category of Computer & Networking \\ network products \\ network cards. Further, it is possible to filter the selection of necessary for us to parameters such as brand, price, delivery and other conditions.

• wireless protocol.

Wireless routers

wireless router is a device that performs the router functions as well as wireless access point. This device is used to provide access to the Internet or a private network. It can function in a wired LAN (local area network), only a wireless LAN (WLAN), or a mixed wired / wireless network, depending on the manufacturer and model.

Most modern wireless routers have the following characteristics:

• one or more network adapters, supporting Fast Ethernet or Gigabit Ethernet integrated into the main SoC;
• one or more supporting part WNICs IEEE 802.11 standard family are also integrated into the main SoC or as separate chips on a circuit board. It can also be a separate card that is connected through a MiniPCI or MiniPCIe interface;
• some wireless routers have 1 or 2 USB ports. For wireless routers with 1 USB port, it is designed for any printer or a desktop / mobile external hard drive. For wireless routers with two USB-ports, one for the printer, and the other is designed for desktop computers or mobile external hard drive;
• some wireless routers have a USB-port, specially designed for connecting a mobile broadband modem.

As a result you can get: file sharing, one stream music, video chat, print, etc. (Bluetooth functions depend on the model).

This device consumes little power from the PC / laptop, has an intuitive interface and functionality, small size.

Aliexpressit offers a huge selection Bluetooth adapters various types and configurations.

3G modems

3G modem It is a device that allows the computer to connect to the Internet via a high-speed mobile broadband connection. This means that the signal is transmitted to the Internet through radio broadcasting, and is not sent through a cable or phone line. The technology is largely the same as that used for the delivery of Internet content in today's mobile phones.

There are a number of broadcasting standards, which come under the name of 3G. The most common UMTS and CDMA standards. Because different standards are not always compatible with each other, the user should check that 3G modem is compatible with the network of which they are going to get 3G services.

In most cases, 3G modem - a removable device is usually connected to a USB slot on your computer and reminds portable storage drive.

modems

Modem It is a device that enables a computer to transmit data on, for example, telephone or cable lines. Computer information is stored digitally, whereas information transmitted over telephone lines is transmitted in the form of analog waves. The modem converts these two forms (analog and digital).

Fortunately, there is a standard interface for connecting external modems computers under the name RS-232. Consequently, any external modem can be connected to any computer that has an RS-232 port, it has almost all personal computers. There are also modems, which look like an expansion card can be inserted into an available expansion slot. They are sometimes referred to as internal modems.

Network switches

Most business networks today use switches to connect computers, printers and servers within a building or campus. The switch serves as a controller that allows network devices to effectively inform each other.

In a telecommunications network, switch is a device that will accept data from any of multiple input ports to the specific output port.

USB Wi-fi adapters

If you bought your laptop for the past seven years, he probably already is equipped with Wi-fi card. But in older models, it might not be. In addition, very few internal wireless card without antenna can get the same reception as an external adapter. USB Wi-fi adapters allow to receive the signal even in the presence of several walls or floors between you and the router.

Many laptops, issued before 2015 do not have the ability to decrypt the newest, fastest wireless standard: 802.11ac. With that help manage just such adapter.

When choosing USB Wi-fi adapter pay attention to the wireless protocols it supports, to the USB port of any generation, it is connected to (2.0 or 3.0), and how it uses bandwidth (2.4 GHz or 5 GHz). Then you need to check which USB ports have your laptop: USB 2.0 or USB 3.0. If the laptop only has USB 2.0, the theoretical maximum speed, which may reach 60 Mb / s. While, USB 3.0 reaches a speed of 640 Mb / s. But it does not really matter if your router uses 802.11n only (whose maximum speed of 56Mb / s).

Firewalls and VPN

VPN receives information (or data packets) to be sent to the user's computer and encapsulates it in another layer of protection, known as the tunneling protocol. This protocol protects the contents from viewing by unauthorized persons. Protected packets are then sent over the Internet to the destination where the tunneling protocol is removed and the information is presented to the recipient in its original form. This is a very simple way by which works VPN. firewalls They work by blocking unwanted packets of information. The firewall knows what data is undesirable, since it is configured by the user or the operating system. These data can be the IP address, web address, port, or even specific words or phrases.

When the information arrives at the firewall, it is checked for data that the user has defined as unwanted or harmful. If there is a match with the set of data the user firewall rejects and discards them. If not, the data passes through the firewall.

Various virtual private networks have different settings and configurations, but, as a rule, they require three main types of equipment: network access server, firewall and AAA server.

The network access server sets and supports each tunnel, which operates in a virtual private access network. The firewall provides a barrier between the private network and the Internet, while the AAA server determines that this user may or cannot access the network (authorization), and registers all the actions that the user does when connected to the network.

In addition, there are several other types of equipment that are often used in virtual private networks, including:

• VPN Hub: Works similarly to the AAA server, but connects to the generic server. Can handle a large number of simultaneous compounds;
• VPN client: to connect a large number of computers to one device;
• VPN - Firewall: Works as an ordinary firewall, but has an additional feature, can manage traffic in accordance with the specification of the virtual private network;
• VPN router: Works as a regular router, but can manage traffic in accordance with the specification of the virtual private network.

firewalls There are so many equipment options.

Wired routers

Wired routers Usually used in large office complexes. Such routers are usually cheaper than wireless options. These routers offer broader network security capabilities. Currently, wired broadband routers can also perform the DSL modem or hub functions, as well as act as a network screen.

Network hubs

Concentrator It is a common point of connection for devices on the network. They are commonly used to connect the segments of the local network. The hub contains several ports. When the package arrives on one port, it is copied to other ports so that all local network segments can see all packages.

The passive network hub serves as a channel for data, which allows you to move from one device (or segment) to another. So-called intelligent centers include additional features that allow the administrator to monitor traffic passing through the hub and configure each port. Intelligent network hubs are also called controlled hubs.

Third type of concentrator, called Switch, reads the address of destination of each package, and then sends a package to the appropriate port.

Network hubs are usually easy to install and maintain, which makes these devices with a good option for home networks.

Network corps

Network housing Data storage is a storage device that provides the connection of the hard disk (HDD) to the network. Network housings can be purchased either with different amounts of empty compartments, which can be separately purchased hard drives or solid-state drives, or with pre-filled disks.

In the section Network equipment on Aliexpressyou can select the network housing of the specified configuration.

Network adapters

Network adapter It is an internal computer hardware component that is used to exchange data over a network with another computer. This allows the computer to connect to another computer, server, or any network device via a local network connection. The network adapter can be used via a wired or wireless network.

Print servers

The print server allows computers on the network to access a network printer. Print serversTherefore, even on very small networks. They deprive the need to move the files from the computer to the computer before printing.

Advantages:

• allow any number of users to use the same printer;
• no need to move files to a computer that is connected directly to the printer.

Disadvantages:

• most features of multifunctional printers (such as fax and photocopying) are not supported by print servers;
• some printers such as GDI printers use their own teams that make them unsuitable for use on print servers;
• there are significant differences between USB compatibility printers and non-USB printers.

Find a print server on Aliexpressyou can in Computers and Network Equipment\u003e Office Electronics\u003e Print servers.

Finding Wi-Fi

Search Wi-Fi promotes a special chip that is mounted in a computer, telephone or other device. Its main functions are the search for available data networks, exchange information between users, information transfer to a remote printer, etc. Main advantages - high speed, direct connection, greater range (relatively with Bluetooth).

Mini wifi adapter Allows you to double the coating of the base Wi-Fi signal, providing its safety.

Reviews for the best selling wi-Fi adapter.

V *** o B. RU
The goods arrived in 16 days. Prior to that, I used the EDIMAX WiFi adapter (micro USB WiFi). Subjective assessment such as the quality and stability of the signal increased. When using EDIMAX, the signal was walked from 30 to 102 (two concrete walls) Mbps, the adapter was grain to 80-90 ° C. When using an ordered WiFi adapter (802.11n USB Wireless Lan Card), the signal value increased from 54-102 to 102-150 Mbps and its level (signal quality) increased from 40-60% to a stable 100%. Hears tolerant, up to 40-60 OS. Now interruptions with the Internet TV arise only by the fault of the provider, which at its discretion changes the speed of the Internet. Product quality, deserves attention. Recommend. The adapter came without drivers, downloaded himself. Everything has earned after rebooting the computer. Seller thanks. Of the minuses - the USB connector is crooked. Assessment for this did not reduce.
