Beyond 11ac: Interpreting 802.11ad and 11ax
Recently, an international chip giant announced the launch of a three-frequency 802.11ad chipset. It is understood that the chipset will be the core component of a home wireless router, it will integrate 60 GHz 802.11ad technology with 5 GHz and GHz 802.11ac. It is a three-frequency access point chipset.

domain can have up to 256 bus, each bus can support 32 devices, so the device number is 5 bits, and each device can have up to 8 functions, so the function number is 3 bits. Thus, we can conclude that the address of the above PCI device is the number 1th function on the No. 31st device on the No. No. 0 field No. 0 bus.What exactly is this PCI device? The following is the output of the LSPCI command on my computer:00:00.0 host Bridge:intel Corporation 82845 845 (Brookdale)
down.
The second basic concept is the memory address. Generally, 32 MB, 64 MB, or MB memory is installed on our machine. Each byte of memory is assigned an address, so that the CPU can access the memory. The 32 MB address range is expressed as 0 ~ in hexadecimal notation ~ 1 ffffffh, where 0 ~ Fffffh's low-end 1 MB memory is very special, because the first 8086 processor can access a maximum of 1 MB of memory, which is known as the basic memory at the low end of 1 MB 640kb, while a0000h ~ Bfff
have up to 256 buses, and each bus can support 32 devices, therefore, the device number is five bits, and each device can have a maximum of eight functions, so the function number is three bits. As a result, we can obtain that the IP address of the above PCI device is the No. 1 function of the No. 31 device on the Bus No. 0 in the 0 domain.So what is the above PCI device? The following is the output of the lspci command on my computer:. 0 host bridge: Intel Corporation 82845 845 (Brookdale)
(corresponding module is USB core. O ). Although this step is quite straightforward, the next Linux USBThe setup steps are confusing. In particular, you now need to select the correct USB master controller driver for the system. The option is "EHCI"(Corresponding module is ehci-hcd.o), "uhci" (corresponding module is usb-uhci.o), "uhci (Alternate)Driver) "and" OHCI "(corresponding module is usb-ohci.o ). This is where many people are confused about Linux USB. To understand "EHCI" and what it i
has to discard the 850 chipset and re-launch the 845 chipset that supports SDRAM to match P4. This may be the case when we buy P4 earlier.
Motherboard In fact, the performance of P4 is restricted by the memory. The 845d, 848, and other chipsets that later support DDR single-channel memory did not solve the problem perfectly.
Later, the 865 chipset that support

4. Memory Address Concept
Generally, 32 MB, 64 MB, or MB memory is installed on our machines. Each byte of these memory is assigned an address so that the CPU can access the memory. The 32 MB address range is expressed as 0 ~ in hexadecimal notation ~ 1 ffffffh, where 0 ~ Fffffh's low-end 1 MB memory is very special, because the first 8086 processor ca
introduced. Each PCI domain can have up to 256 buses, and each bus can support 32 devices, therefore, the device number is five bits, and each device can have a maximum of eight functions, so the function number is three bits. As a result, we can obtain that the IP address of the above PCI device is the No. 1 function of the No. 31 device on the Bus No. 0 in the 0 domain. So what is the above PCI device? The following is the output of the lspci command on my computer:. 0 host bridge: Intel Corp
Ethernet. If there is a heavy network load, you can consider a Gigabit Ethernet Card. If you cannot buy a gigabit network card, you can use multiple network cards to create a virtual network card with the same IP address. In Linux, this technology is called bonding. Bonding is included in the kernel above linux2.4. You only need to select bonding driver support in the network device option during compilation, as shown in figure 1. Of course, the prerequisite for using Bonding Technology to conf

In the past few days, I have helped students read their laptops and learned a lot about them. At the same time, I am deeply impressed by the differences between the notebook market and the desktop market, not to mention the complexity and confusion of various brand series and models (just an IBM t42 series has dozens of models, each model is followed by three numbers/letters, so that outsiders do not know the so-called), just say that the commonplace of the company, Pentium M, sai Yang m, as wel
system performance, and network hardware I/O is especially important to servers. Currently, most Linux servers use 10/100 MB Ethernet. If there is a heavy network load, you can consider a Gigabit Ethernet Card. If you cannot buy a gigabit network card, you can use multiple network cards to create a virtual network card with the same IP address. In Linux, this technology is called bonding.

North Bridge, South Bridge is the most important two on the Motherboard chipset. they are all bus controllers. they are bus control chips. relatively speaking, the North Bridge is more important than the south bridge. the North bridge connects to the system bus and is responsible for CPU access to memory. at the same time, this AGP plug-in is connected to control the PCI bus, and the system bus and local bus are cut off.
