SATA、IDE和SCSI介绍

有些话、适合烂在心里 提交于 2019-12-01 21:54:10
目前硬盘接口类型不算多,主要有IDE、SCSI、SATA三种。IDE许多时候以Ultra ATA指代之,很多人习惯将Ultra ATA硬盘称为IDE硬盘,但需要说明的是IDE的概念要大于ATA——原则上所有硬盘驱动器集成控制器的设计都属于IDE,SCSI也不例外。当然,以IDE指代ATA已经形成很大的惯性,SATA开始将IDE与ATA区别开来。成熟廉价的是IDE,最新兴的是SATA,稳定价高的SCSI。最早出现的是IDE接口,后来出现SCSI接口,主要面向服务器。如果仔细观察,你可以发现,最近电脑业界的系统总线都是朝串行发展,硬盘的接口总线SATA是个代表,包括今后的将要顶替AGP接口的图形接口标准PCI-Express,都朝着串行方向发展。 1. IDE接口: IDE的英文全称为:Integrated Drive Electronics,是目前最主流的硬盘接口,包括光储类的主要接口。它经过数年的发展变得很成熟、廉价、稳定。IDE接口使用一根40芯或80芯的扁平电缆连接硬盘与主板,每条线最多连接2个IDE设备(硬盘或者光储)。早期的是用IDE多功能卡插在主板上,再连接IDE线,这功能卡已经淘汰;目前主板全部提供2个IDE接口,相比IDE多功能卡,它显得价格便宜和易于安装。IDE接口又分为UDMA/33,UDMA/66,UDMA/100,UDMA/133。1996年底

IDE、SCSI接口区别

原文地址: http://www.videostar.com/servers/article/listArticle.asp?ID=801 目前存储设备的接口有五大类:IDE、SCSI、USB,并行口,串口,其中并行口与串口的速度非常慢,不提也罢,最主要的就是IDE,usb,SCSI。IDE(Integrated Drive Electronics,电子集成驱动器)凭着其高速的传输和平常的价格,受到普通用户的欢迎,而usb设备大有后来者居上之势,至于SCSI(Small Computer System Interface,小型计算机系统接口),速度、性能和稳定性都比IDE要好,价格当然也要贵得多,主要面向服务器和工作站市场。 在过去的几年间,IDE进步得很快,Ultra DMA 33推出不到两年,Ultra DMA 66就上市了。其实,SCSI的发展一点也不比IDE慢,只不过我们较少接触,对其了解不深而己。SCSI的标准从1980年开始实行,但到现在还未统一,各厂商对它的命名不相同,容易令人混淆是最主要的原因,下文介绍了SCSI接口的各个方面,希望对准备购买SCSI设备的朋友有所帮助。    一、概述    SCSI是一种连结主机和外围设备的接口,支持包括磁盘驱动器、磁带机、光驱、扫描仪在内的多种设备它由SCSI控制器进行数据操作,SCSI控制器相当于一块小型CPU

How to setup SDK in IntelliJ IDEA?

好久不见. 提交于 2019-12-01 21:46:14
I am not finding any way to setup the SDK in IntelliJ IDEA. Not finding any path to setup the SDK in ubuntu 16.04 LTS for IntelliJ IDEA. I am working in this IDE for working on mongodb. But can't proceed because of this problem. To find the path where java is installed on ubuntu, you can run the following command from terminal: $ whereis java You may get something like this: java: /usr/bin/java /etc/java /usr/share/java /usr/lib/jvm Which means that the java resides at one of the above paths as for example /usr/bin/java So, that directory should designate in IntelliJ. You can configure in the

How to make PHPStorm treat a function as defined?

会有一股神秘感。 提交于 2019-12-01 21:08:28
The double_metaphone() function is defined in a PECL extension and as such PHPStorm cannot see it being defined. I wouldn't like to see any warnings about this. I assume I could make PHPStorm treat this function call as defined through some kind of annotation but I don't know how to make this happen. You need what is called "stub files": Create a .php file and place it anywhere in your project (be it project itself .. or as some External Library (Settings | PHP | Include paths) -- does not matter, as long as PhpStorm can see it in this project). Add that function definition as it would be done

I updated PyDev (Eclipse) yesterday and now it is telling me that None, name and other reserved words/builtin functions are invalid, but the script runs just fine.

The errors: Undefined variable main Undefined variable None Undefined variable int Undefined variable eval I am running eclipse Juno and PyDev 2.7.4. also, I notice that the errors only appear after the PyDev code analysis ends.

How do I disable some inspections for modules in IntelliJ IDEA?

拜拜、爱过 提交于 2019-12-01 19:41:09
问题 In IntelliJ IDEA, I can disable some inspections for a class, method, or other units. I have a module in a project that's a library that I am not the only consumer of. I do not use all the methods in the library and consequently a large number are marked 'unused'. These are all false positives. I would like to disable these inspections for this module alone (ideally, I'd like to disable unused warnings for public/protected methods). Is this possible? If so, how would one go about doing this?

  IDE是集成开发环境:Integrated Development Environment的缩写。   使用IDE的好处在于按,可以把编写代码、组织项目、编译、运行、调试等放到一个环境中运行,能极大地提高开发效率。   IDE提升开发效率主要靠以下几点: 编辑器的自动提示,可以大大提高敲代码的速度; 代码修改后可以自动重新编译,并直接运行; 可以方便地进行断点调试。   目前,流行的用于Java开发IDE有   Eclipse    Eclipse 是由IBM开发并捐赠给开源社区的一个IDE,也是目前应用最广泛的IDE。Eclipse的特点是它本身是Java开发的,并且基于插件结构,即使是对Java开发的支持也是通过插件JDT实现的。   除了用于Java开发,Eclipse配合插件也可以作为C/C++开发环境、PHP开发环境、Rust开发环境等。   IntelliJ Idea    IntelliJ Idea 是由JetBrains公司开发的一个功能强大的IDE,分为免费版和商用付费版。JetBrains公司的IDE平台也是基于IDE平台+语言插件的模式,支持Python开发环境、Ruby开发环境、PHP开发环境等,这些开发环境也分为免费版和付费版。   NetBeans    NetBeans 是最早由SUN开发的开源IDE,由于使用人数较少,目前已不再流行。

You can replace across all files from the Replace text box, replace all in one file or replace a single change. https://code
