Specifically: NicWork on the MAC Sub-layer in the data link layer, rather than the physical layer. Nic is used to convert parallel lines. That is, the MAC Sub-layer specifies how frame is transmitted on a physical line. The role of LLC is to identifyEncapsulation is performed based on different protocol types. The MAC address is burned into the NIC. Therefore, the NIC works on the data link layer. I. MAIN FEATURES OF NICs Network interface card (NIC), also known as network adapter, is a device

I am very interested in Linux systems. Common Linux sysfs features Linux itself is the core part of this operating system, that is, the operating system kernel. The kernel is the most basic program for completing operations. It is responsible for the startup and termination of other programs, such as text editor programs, memory application processing, hard disk access, and network connection management.
The key to using Linux sysfs is to master the usage of these sysfs attributes. The following
Detailed explanation of lspci commands in CentOS
Note:Lspci is a tool used to display all PCI bus devices in the system or all devices connected to the bus.
Parameters:
-V enables lspci to display the details of all devices in redundancy mode. -Vv enables lspci to display more detailed information in redundancy mode (in fact, everything that PCI devices can provide ). The exact meaning of the data is not ex

What do you mean, m.2?
M.2 is a new solid-state hard disk interface, is an alternative msata new interface specification, which we used to refer to NGFF, English is all called: Next Generation Form Factor.
M.2 Interface SSD The main advantage is that the volume is smaller than the traditional SATA3.0 and mSATA, and the reading speed is faster, which is better for some mobile device compatibility.
The difference between m.2 and SATA3

I have already learned some basic BIOS basics, and settings, so in this article I will give a more detailed introduction of the BIOS overclocking settings, I hope for those who want to overclocking but did not pick up the overclocking player can have some help.
As with the AMI bios, press the "Del" key to enter the BIOS setup menu (some press the F1 key) when the screen is powered on:
After entering, you will see the following menu, there may be some differences, but basically the same, and th

Some interruptions in the system are hard-wired. For example, the periodic timer of the real-time clock may be fixed to Pin 3 of the interrupt controller. Other pins connected to the controller can only be determined by the Control card inserted into the specific ISA or PCI slot. For example, pin 4 in the interrupt controller may be connected to the PCIe slot No. 0, but an Ethernet card may be inserted in the slot one day and changed to t
