certain share of the market at a low price. However, due to the low network transmission rate of the 10 Mbps ISA plug-in Nic and occupying a large amount of CPU resources, only applicable to LAN with low speed requirements. Therefore, we recommend that you use a 100 Mbps PCI plug-in or a 10 Mbps/Mbps adaptive Nic, Which is inexpensive and can be adapted to a large number of users, an application environment that transfers large amounts of data online

1. Search for a restaurant Traveling Abroad and tasting local food are one of the highlights of the trip. However, as a stranger, you naturally cannot know the reputation of each restaurant.

Can you introduce a well-known restaurant nearby?Cocould you recommend a nice restaurant near here? I want to go to a restaurant at a reasonable price.I want a

Disk Array: Disk Array (Redundant Arrays of Inexpensive Disks, raid) fault-tolerant Inexpensive Disk Array Disk Arrays include hardware disk arrays and software disk arrays. Disk arrays are classified into the following levels: Raid-0 (equivalent mode): optimal performance In this mode, disks of the same model and capacity are used for the best effect. In this mode, raid switches the disk out of an equal nu

and relatively inexpensive. If Joe or Mary's website becomes more popular, Irene Network service provider can provide Joe or Mary with more servers right awayIn this example, the browser sends an HTTP request to www.joes-hardware.com to the IP address of the Joe Server, sending a request to www.marys-antiques.com to the Mary server (different from Joe) 's IP addressVirtual HostingMany people want to show themselves on the web, but their website is no

1. When executing scripts, you can use./or. ./(dot space dot slash) to execute scriptThe./means that another shell is started to execute the script (another process), so when a slash executes the script, the environment variables set will end with the process exiting, where the environment variable settings do not work for the current shell.. ./equivalent to source./execute the script, source is the command in the execution script, that is, the command is executed in the current process, so the

In the 2013 era of the Internet, whether computers or mobile phones, even television and watches are used on the network, but some need wireless network, such as smart phones and smart watches because of small size, can not design a network connection port, can only use wireless convenience to achieve the Internet. So most families in order to be able to let the family's mobile phone or tablet computer Internet, installed wireless router, wireless router now cheap affordable,

: Internet server usage is an important application of Linux. Internet and intranet servers based on Linux and Apache are inexpensive, performance-friendly, and easy to maintain. In the United States, most inexpensive servers are based on Linux. According to Infobeads's review, 26% or more ISPs are using Linux. Linux can be used as WWW server, domain name server, firewall, FTP server, mail server and so on

, generally speaking, this time will also have some money, so add some webserver server, in this add webserver server process, there may be several challenges:1. Apache soft load or LVS soft load can not bear the huge amount of web traffic (request connection number, network flow, etc.) scheduling, this time if the funding allows, the plan is to buy hardware load balancing equipment, such as F5, Netsclar, Athelon and so on, If the funds are not allowed, the plan is to make the application logica

, SandForce, Samsung and JMicron, Phison and so on. Different company's product, the characteristic is different, the performance and the price difference is many. Some inexpensive SSD, basically use a few price comparatively inexpensive of the Taiwan series product, performance is fair, still more superior than mechanical hard disk. Medium and high-end products, most of the use of Marvell/sandforce chips.
