10 Gigabit Ethernet
The number of standard network connectors RJ-45 format 10 Gigabit Ethernet provided in the design of the device.
This format belongs to professional ones: it provides speeds up to 10 Gbps (which is reflected in the name) and is intended mainly for tasks related to processing large volumes of traffic. Nevertheless, Gigabit Ethernet support is now found even in PC and laptop network controllers, not to mention more specialized equipment. And the number of connectors corresponds to the number of devices that can be directly connected via this interface at the same time. It should be borne in mind that in some "switches" individual connectors of this type are combined with optical SFP or SFP +. Such connectors are marked "combo" and are taken into account both when counting RJ-45 and when counting SFP / SFP +.
Of which dedicated WAN/LAN
The number
of WAN/LAN combo ports specified by the manufacturer in the device design that can be reassigned to work with both an external WAN and a local LAN. Such a solution allows to reduce the total number of connection ports and at the same time expand the functionality of the equipment for flexible adaptation to user needs.
USB ports
The number of
USB ports provided in the design of the router. USB is a universal interface used in computer technology to connect peripheral devices for various purposes. One of its uses is to connect a 3G modem (if provided, see “Data entry (WAN-port)”), but this is not limited to this: in fact, the options for using USB ports directly depend only on the capabilities specified in the router firmware. So, in some models, you can connect a flash drive or an external hard drive to this connector — to update the firmware or even organize an FTP server directly on the router. And for other peripherals — printers, cameras, etc. — USB connection can be used to work as network devices (however, such functions are rare in standard firmware).
CPU cores
The number of cores in the processor installed in the device. The core in this case refers to the part of the processor that executes one thread of instructions. Accordingly, the presence of multiple cores allows you to work with multiple threads simultaneously, which has a positive effect on performance.
