With the role attribute, authors can annotate XML languages with machine-readable semantic information about the purpose of elements. RDFa is a Recommendation. When a device sees a message addressed to it, that device copies the message and then marks that message as being read.

These include using the body element with bgcolor, text and link attributes. This document is intended to help make XHTML-family markup languages more effective at supporting the needs of the accessibility community by providing a generic mechanism for defining the relationship between document components and well-known accessibility taxonomies.

However, in this day and age simply having internet is not enough, you need to be able to get high speeds that all companies from Verizon to Megapath should be able to provide. In peer-to-peer networking there are no dedicated servers or hierarchy among the computers.

Intranet With the advancements made in browser-based software for the Internet, many private organizations are implementing intranets.

Ethernet connection is popular because it strikes a good balance between speed, cost and ease of installation. Data is transmitted in tokens, which are passed along the ring and viewed by each device. Also this layer takes note of the electrical signals that transmit data throughout system. It also provides an implementation using XML Schemas.

When these computers are joined in a network, people can share files and peripherals such as modems, printers, tape backup drives, or CD-ROM drives.

Managers must determine the number of users in each site on the network that need the higher throughput, decide which segments of the backbone need to be reconfigured specifically for BASE-T and then choose the necessary hardware to connect the BASE-T segments with existing 10BASE-T segments.

Modularization of XHTML makes it easier to combine with markup tags for things like vector graphics, multimedia, math, electronic commerce and more. This model is the best known and most widely used guide to describe networking environments. For large organizations, an intranet provides an easy access mode to corporate information for employees.

This is accomplished by connecting the different LANs using services such as dedicated leased phone lines, dial-up phone lines both synchronous and asynchronoussatellite links, and data packet carrier services. The division of labor between the different processors enables the application designer to place an application function on the processor that is most appropriate for that function.

As the message makes its way along the ring, it eventually gets back to the sender who now notes that the message was received by the intended device.

Web Programming Step by Step, 2nd Edition

All of the computers are equal and therefore known as peers. See also the list of translations produced by volunteers.

An intranet is a private network utilizing Internet-type tools, but available only within that organization. This second version of this specification includes several minor updates to provide clarifications and address errors found in the first version.

Internet websites now provide personal, educational, political and economic resources to every corner of the planet. The modular design reflects the realization that a one-size-fits-all approach no longer works in a world where browsers vary enormously in their capabilities.

Thus, if you want to validate the document, the tool used knows which variant you are using. Gigabit Ethernet is a future technology that promises a migration path beyond Fast Ethernet so the next generation of networks will support even higher data transfer speeds.

A W3C Recommendation indicates that consensus has been reached among the Consortium Members that a specification is appropriate for widespread use.Basic Networking Tutorial - a network is any collection of independent computers that communicate with one another over a shared network medium.A computer network is a collection of two or more connected computers.

When these computers are joined in a network, people can share files and peripherals such as modems, printers, tape.

* 원래 웹사이트의 아이콘을 먼저 만드는 작업을 하려고 했는데, 디자이너의 작업이 늦어지면 이러한 아이콘 또한 늦게 나오기 마련이다. * 지난번에 이어서 이번에는 HTML과 CSS로 드롭다운(드랍다운/drop down) 가로형 메뉴를 만드는 것을 해보자. 기존에는 플래시를 이용하거나 복잡한 자바스크립트를 사용해야했지만 이제는 CSS와 HTML만으로도 다양한 효과의 드랍다운 메뉴를 만들 수 있게 되었다. In Lecture One, we learned that HTML and CSS are languages that work together to describe the structure and presentation of a Web page.

We also learned that, while HTML markup is essential to the structure of any Web document, it falls short in. Learn the basics of HTML and CSS.
