[From: an in-depth understanding of Linux kernel]
Linux tries to keep a clear line between hardware-independent source code and hardware-related source code. To achieve this, the arch and include directories contain 23 sub-directories to correspond to different hardware platforms supported by Linux. The standard names of these platforms are as follows:
Alpha
HP's Alpha workstation was first owned by digital, and later belongs to Compaq, which is no l

In the initial PC design, CPU, ram, and I/O are connected by a bus, and all components must work in the synchronous mode, the CPU determines the frequency at which other devices operate. This will bring about a locked to each other effect, that is, everyone is limited to a universal clock frequency (clock frequency) that all devices can withstand, the overall performance of the system is not high.

Yesterday, a good wcf Service needs to be published to a virtual directory under the server site.The publishing process encountered a problem: the environment on the server is https, so you need to modify the configuration file.So I found a problem on the Internet, but the problem still persists. I found an article on the InternetFollow the instructions above step by step.

I. Forgot the system password
If you forget the system password in the CMOS settings, you will not be able to start the machine. The solution is to open the chassis, remove the battery, connect the positive and negative poles, and discharge the CMOs, clear all the content in CMOS (including the password, of course), and then restart the system to set it.
Note: For some motherboard With the CMOS Password clear jumper, refer to the motherboard manual to transient the jumper, so that the CMOS pass
Project Management Personnel achieve the eight required capabilities at the highest level

There is now an emerging global trend in the project management field: enterprises are making significant investments in the development of their project managers, while providing them with a direct path to senior management.For many years, there has been only one way to promote to the highest level of enterprise: You mu
technological development, and manufacturers also recognize this bottleneck. At this time, COMPAQ, Hewlett Packard, Intel, Lucent, Microsoft, NEC, and PHILIPS jointly developed the USB 2.0 interface standard. USB 2.0 increases the data transmission speed between devices to 480 Mbps, about 40 times faster than the USB 1.1 Standard, the biggest benefit of speed improvement for users is that users can use more efficient external devices, and peripheral
can perform load balancing between nodes. Although the cluster system itself is independent of the software or hardware it is using, the hardware connection plays a key role in the effective operation of the system.GiganetGiganet is the first supplier of Virtual Interface (VI) architecture cards for Linux. It provides cLAN cards and switches. The VI architecture is a platform-independent software and hardware system developed by Intel for cluster creation. It uses its own network communication

For most Internet services, they are Read-intensive applications. The Distributed File System uses a local hard disk as a Cache space such as 2Gbytes on each server ), the local access speed to the distributed file system is close to that to the local hard disk.In addition, the development of storage hardware technology also promotes migration from a no

Recently, CPCI was used in the project, and the information about PCI was collected online. CPCI is a subset of PCI. The bridge chip used is divided into two types: master and slave. As for PCI, I will describe it as follows:
With the rapid development of Windows Graphical User interfaces and the wide application of multimedia technology, the system requires high-speed graphic processing and I/O throughput, this makes the original ISA and eisa bus far from bei

At present, even these server manufacturers have begun to give up on their own, switch to IA, and launch more and more Ia architecture servers to survive.
Currently, the main server processors using this arch
My notebook is very old: HP Compaq 6515b,
I have tried to install Linux in many releases.ProgramCannot be started.
After repeated attempts, I successfully installed opensuse on the notebook. If a friend uses the same notebook, try to install opensuse.
After installing the driver, discard the 480*800 resolution of the victim. It's nice to open vi

Instead, I started my Google journey again.
The larger the memory, the faster the machine? I think most people answer yes. The prompt from m to m is obvious, so it is assumed that the improvement from m to 1G will be obvious. However, I will tell you through my personal experience that 1 GB of memory is slower than MB, provided that you do not set anything.
A few days ago, I expanded my Compaq n1_c to 1 GB memory and 2 × 512 M pc1_sd. After the expansion, I found that the machine is not onl

At present, in the microcomputer system, various peripherals used to expand computer functions are constantly appearing. Correspondingly, the ports on the chassis are getting increasingly tight. Because of the lack of a two-way, inexpensive bus that supports medium and low-speed peripherals, it hinders the further development of peripheral devices such as modem, scanner, keyboard, mo

and hard disk capacity can be upgraded. Replacing the latest hard disk with a 5400-to-10% ~ An increase of about 15% is satisfactory in terms of noise and energy consumption.
For a laptop, there will never be too much memory. In order to make up for the inherent shortage of hard disk performance, we need more memory capacity to support it. I have tested on my laptop. When the standard memory is 20% MB, the disk performance ratio decreases by nearly 244 (the pcmark2002 HDD score is 296 and res
