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

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.

Compromise between encapsulating code and maintaining a single point of control for each feature element.
The static type language restricts the expression of the language, thus reducing the effect of preventing rogue tiles. A common type can compensate for this flaw in the Java language to some extent.
All captured or declared detected exceptions must be thrown, which means that some code in the method cannot be extracted.

Linux firewall named FLOPPYFW can be stored in a normal floppy disk and run independently in RAM memory. It enables you to start your computer, use IPChains to filter out unwanted IP packets, and use it to configure IP camouflage (IP masquerade), the monitoring port, through which you can use the host to remotely control computers in other networks. The FLOPPYFW function is very powerful, but it requires a very low hardware environment, in addition to a floppy disk, as long as 8MB of memory is

If you have problems installing NETMOS multi-serial port cards, please help solve the problem-Linux general technology-Linux technology and application information. The following is a detailed description. There are two pci netmos serial port cards in the machine, but the system can only find four serial ports and cannot add them by yourself. How can I add them correctly:

of the system will be much slower to communicate with the processor, this results in a loss of system performance. Therefore, if your CPU can reduce the frequency doubling, try again!The external frequency speed is usually closely related to the speed of the front-end bus and memory. Therefore, when you increase the external frequency of the CPU, the performance of the CPU, system, and memory is also improved, which is why DIYer prefers the overclock.Now let's get down to the point.
