An access control mechanism mediates between a user (or a process executing on behalf of a user) and system resources, such as applications, operating systems, firewalls, routers, files, and databases. The system must first authenticate (验证) a user seeking access. Typically the authentication function determines whether the user is permitted to access the system at all. Then the access control function determines if the specific requested access by this user is permitted. A security administrator maintains an authorization (授权) database that specifies what type of access to which resources is allowed for this user. The access control function consults this database to determine whether to grant access. An auditing function monitors and keeps a record of user accesses to system resources.
In practice, a number of components may cooperatively share the access control function. All operating systems have at least a rudimentary (基本的), and in many cases a quite robust, access control component. Add-on security packages can add to the native access control capabilities of the OS. Particular applications or utilities, such as a database management system, also incorporate access control functions. External devices, such as firewalls, can also provide access control services.
IV. Translate the following passage from English into Chinese:
入侵者攻击从温和的到严重的形形色色。在这一系列攻击的温和端，有许多人只是希望探查互联网，看看那里有什么。在严重端的是试图阅读特许数据、对数据进行未经授权的修改或扰乱系统的个人。
入侵者的目标是获得进入一个系统的机会，或者增加在一个系统中可以使用的特权范围。初始攻击大多利用系统或软件的脆弱之处，这些脆弱之处允许用户执行相应的代码，打开进入系统的后门。入侵者可对具有某些运行特权的程序实施像缓存溢出这样的攻击，利用此类攻击获得进入一个系统的机会。
另外，入侵者也试图获取应予保护的信息。在有些情况下，这种信息是以用户口令的形式存在的。知道了某个其他用户的口令之后，入侵者就可以登录系统并行使赋予合法用户的所有特权。

Instant messaging has always been a good way to stay in touch with friends. As companies look to cut costs and improve efficiency, instant messaging is a good way to replace in-person meetings, while allowing people to collaborate (合作) through their computers. Instant messaging is a valuable new tool that is becoming as common as e-mail in the workplace.
Several companies, such as Yahoo!, AOL, and Microsoft, will give you free access to instant messaging. To use their systems, you will need to download their software to your computer from their websites. Some instant messaging programs include the ability to send live audio or video. With a microphone and/or digital camera mounted on your computer, you can let other people see and hear you talking.
Most instant messaging programs ask you to sign in with a password. Then, you can create a list of other people with whom you want to converse (交谈). To begin a conversation, send a message to the others to see if they are at their computers. Their computers will open a window or make a sound to tell them you want to talk to them. If they respond, you can start writing back and forth. IV. Translate the following passage from English into Chinese:
新技术带来的变化速度对于全世界人们的生活、工作和娱乐方式产生了重要影响。新兴技术对传统的教学过程以及教育的管理方式提出挑战。人们经常断言，推动当今社会发生变化的最强有力因素将证明是信息技术。信息技术虽然本身就是一个重要的学习领域，但同时也在所有的课程领域产生着重大影响。方便的全球通信使我们可以即时访问巨量的数据。快速的通信，加上在家里、工作场所和教育机构使用信息技术机会的增多，可能意味着学习成为一项真正持续终生的活动；在这项活动中，技术变化的速度迫使我们要对学习过程本身不断作出评估。
