The user interface function facilitates creation and use of appropriate computational structures by a user. This function typically involves the use of a command language or a menu. The resource allocation function allocates resources for use by a user's computation. Resources can be divided into system provided resources like CPUs, memory areas and IO devices, or user-created resources like files which are entrusted to the OS.

Unit 5 Computer Networks 5.1 Internet
The World Wide Web is an architectural framework for accessing linked documents spread out over thousands of machines all over the Internet. Since the Web is basically a client-server system, we discuss both the client (i.e. user) side and the server side. The Client Side. From the users' point of view, the Web consists of a vast, worldwide collection of documents, usually just called pages for short. Each page may contain links (pointers) to other, related pages, anywhere in the world.

A common form of Internet is a collection of LANs connected by a WAN. The Internet(note uppercase I) means a specific worldwide internet that is widely used to connect universities, government offices, companies, and of late, private individuals. By 1995, there were multiple backbones, hundreds of mid-level (i.e. regional) networks, tens of thousands of LANs, millions of hosts, and tens of millions of users. Backbones The size doubles approximately every year. Much of the growth comes from connecting existing networks to the Internet.
The Internet is a vast global community of real people who constantly generate more unadulterated stuff on more topics than you could ever read in your lifetime. 因特网是现实世界中人们的巨大的全球性社区。在 这个网上，人们在众多主题上不断推出的有价值资料 是你一辈子也读不完的。 If you haven’t tapped into the net yet, here’s what you’re missing: 如果你还没有接近网络，那么下面就是你所缺少的：

OS functions can be classified into •Resource allocation and related functions •User interface functions. The resource allocation function implements resource sharing by the users of a computer system. Basically, it performs binding of a set of resources with a requesting program, that is, it associates resources with a program. The related functions implement protection of users sharing a set of resources against mutual interference.

Users can follow a link (e.g., by clicking on it), which then takes them to the page pointed to. This process can be repeated indefinitely, possibly traversing hundreds of linked pages while doing so. Pages that point to other pages are said to use hypertext. Web pages can combine color desktop publishing, hypertext linking, interactive scripting, sound, video, and even virtual reality. When hypertext pages are mixed with other media, the result is called hypermedia. Pages are viewed with a browser.

Unit 5 Computer Networks 5.1 Internet
Many networks exist in the world, often with different hardware and software. People connected to one network often want to communicate with people attached to a different one. This desire requires connecting together different, and frequently incompatible networks, sometimes by using machines called gateways to make the connection and provide the necessary translation, both in terms of hardware and software. A collection of interconnected networks is called an internetwork or just Internet.
