In recent years the firewall is one kind of protection computer network security technical measure which develops, is also uses the most widespread one kind of network security to protect the technology at The firewall is or a group implements the access control strategy the system, it may be the software, the hardware or software and hardware's union, its goal is provides to the network safekeeping of The firewall usually is located at between the internal network and the exterior network, may monitor, the control and the change the network service which flows between the interior and the exterior network; Controls the exterior computer to be possible to visit the interior the environment which protects, and determined the visit the time, the jurisdiction, the service type and the quality and so on, the inspection interior spreads the information, avoids the privacy information flowing out, achieves resists exterior invades and prevents the goal which the insider information divulges a This article proposed firewall's disposition in network security's importance, has explained the firewall ruleset is the firewall product security important

The firewall is developed in recent years to protect a computer network security technology, is currently the most widely used of a network security The firewall is one or a group of access control strategy for the implementation of the system, which can be software, hardware or a combination of hardware and software, its purpose is to provide security protection for the Firewalls often in the internal network and external networks, can monitor, control and changes in internal and external networks of the mobile communication network; control external access to internal computer protected environment, and to determine the time to visit, competence, the types of service And quality, check the spread of internal information, avoid the outflow of confidential information, to resist external invasion and prevent the leakage of internal information This paper presents a firewall configuration in the importance of network security, explain the firewall rule set is a firewall product safety is an important Key words: network security firewall configuration

在1972年, IBM推出了灵活的软磁盘作为一个中型载货节目到电脑主机由于磁盘这么灵活的,他们被戏称为软盘。他们是物美价廉,规模小,易于处理,存储,并通过发送邮件。大多数的计算机都至少有一个软盘驱动器。软盘,又称为软盘,有两种规格: 5 25英寸。为MS - DOS的基于计算机, 5英寸磁盘,可在720千字节(双-密度) , 1 44兆字节(高-密度),以及 88兆字节(扩展-密度)的能力。该25英寸磁盘有一个密度的48铁轨每英寸,而高密度磁盘有一个密度的96铁轨每英寸。几乎所有的5英寸软盘的密度135tracks每英寸。最早型号的软盘被单一片面的。加上另一个读/写头在磁盘驱动导致使用双面软盘,并增加一倍的容量磁盘。今天,所有软盘是双面的如果你研究了5英寸的软盘上,你会看到一个金属套涵盖读/写插槽。当你插入磁盘到磁盘到磁盘驱动器,金属套幻灯片回来,揭露读/写插槽。读/写头的软盘驱动器,可以清楚自己的定位超过特定的轨道。由于金属套筒和僵化的塑料外壳, 5英寸软盘是那么容易受到损害比25英寸软盘。 利用档案或程式,是在软碟上,你必须先插入磁盘到软盘驱动器软盘驱动器通常被称为甲驱动器和乙驱动器。看看哪个驱动器是甲或者乙有译不正之处见谅!

In 1972, IBM introduced flexible diskettes as a medium for loading programs into mainframe Because the disks were so flexible, they were nicknamed floppy They are inexpensive, small, and easy to handle, store, and send through the Most computers have at least one floppy disk Floppy disks, also called diskettes, are available in two sizes: 5 and 25 For MS-DOS based computers, the 5-inch disks are available in 720-kilobyte (double - density), 44-megabyte (high - density), and 88-megabyte (extended - density) The 25-inch disks have a density of 48 tracks per inch, whereas high-density disks have a density of 96 tracks per Almost all 5-inch floppy disks have a density of 135tracks per The earliest models of floppy disks were single- The addition of another read/write head in the disk drive led to the use of double-sided floppy disk, and doubled the capacity of the Today, all floppy disks are double- If you examine a 5-inch floppy disk, you will see that a metal sleeve covers the read/write When you insert the disk into a disk into a disk drive, the metal sleeve slides back, exposing the read/write The read/write head of the floppy disk drive can position itself over specific Because of the metal sleeve and the rigid plastic casing, the 5-inch floppy disk is less vulnerable to damage than the 25-inch floppy To use the files or programs that are on a floppy disk, you must first insert the disk into a floppy disk Floppy disk drives are commonly referred to as the A drive and the B Check your computer manual to see which drive is A and which is B

What Is Grid Storage? Based on current and proposed products, it appears that a grid storage system should include the following: Modular storage arrays: These systems are connected across a storage network using serial ATA The systems can be block-oriented storage arrays or network-attached storage gateways and Common virtualization layer: Storage must be organized as a single logical pool of resources available to Data redundancy and availability: Multiple copies of data should exist across nodes in the grid, creating redundant data access and availability in case of a component Common management: A single level of management across all nodes should cover the areas of data security, mobility and migration, capacity on demand, and Simplified platform/management architecture: Because common management is so important, the tasks involved in administration should be organized in modular fashion, allowing the autodiscovery of new nodes in the grid and automating volume and file Three Basic Benefits Applying grid topology to a storage network provides several benefits, including the following: R A well-designed grid network is extremely Rather than providing just two paths between any two nodes, the grid offers multiple paths between each storage This makes it easy to service and replace components in case of failure, with minimal impact on system availability or P The same factors that lead to reliability also can improve Not requiring a centralized switch with many ports eliminates a potential performance bottleneck, and applying load-balancing techniques to the multiple paths available offers consistent performance for the entire S It’s easy to expand a grid network using inexpensive switches with low port counts to accommodate additional servers for increased performance, bandwidth and In essence, grid storage is a way to scale out rather than up, using relatively inexpensive storage building

The computer is a product of advanced civilization and its invention, according to some people, signals the advent of a Second Industrial R Formerly a bulky machine that demanded much space, the computer is now becoming smaller and smaller and scientists have made it more sophisticated and accordingly more As is generally known, the computer can do a wide range of work, including complex computation and People now also use it as a teaching aid in An infinite variety of software can be put into the computer, which explains why it is so There is, however, one thing which we should bear in mind: that the computer cannot think but man So there need not be any fear that someday the computer will control us and all we should expect is try our best to bring it to A computer age is not a pipe dream and there will come a day when most of our needs can be met by this wonderful
