Introduction to HTML

HTML or HyperText Markup Language is one of the format used in the production of documents and applications that are running are at the web. HTML is a pure text file that can be created with any text editor. This document is known as a web page, the HTML document is a document that is presented in a web browser. There are two ways of writing an HTML document which will form the a browser page. The first is to use HTML editor or...

Physical Implemantation Of Ethernet

Most of the traffic on the Internet originates and ends with Ethernet connections. Since its inception in the 1970s, Ethernet has evolved to meet the increased demand for high-speed LANs. When optical fiber media was introduced, Ethernet adapted to this new technology to take advantage of the superior bandwidth and low error rate that fiber...

MAC - Getting data to the Media

Media Access Control (MAC) is the lower Ethernet sublayer of the Data Link layer. Media Access Control is implemented by hardware, typically in the computer Network Interface Card (NIC).The Ethernet MAC sublayer has two primary responsibilities:Data EncapsulationMedia Access ControlData EncapsulationData encapsulation provides three primary functions:Frame delimitingAddressingError detectionThe data encapsulation process includes...

Ethernet

Ethernet standart and implementationIEEE StandardsThe first LAN in the world was the original version of Ethernet. Robert Metcalfe and his coworkers at Xerox designed it more than thirty years ago. The first Ethernet standard was published in 1980 by a consortium of Digital Equipment Corporation, Intel, and Xerox (DIX). Metcalfe wanted Ethernet to be a shared standard from which everyone could benefit, and therefore it was released...

Embedded System

Definisi : An embedded system is an application that contains at least one programmable computer (typically in the form of a microcontroller, a microprocessor or digital signal processor chip) and which is used by individuals who are, in the main, unaware that the system is computer-based.žElectronic devices that incorporate a computer (usually...

DNS and Protocol Part II

DNS is a client/server service; however, it differs from the other client/server services that we are examining. While other services use a client that is an application (such as web browser, e-mail client), the DNS client runs as a service itself. The DNS client, sometimes called the DNS resolver, supports name resolution for our other network applications and other services that need it.When configuring a network device, we...

DNS Services and ProtocOl

Now that we have a better understanding of how applications provide an interface for the user and provide access to the network, we will take a look at some specific commonly used protocols.As we will see later in this course, the Transport layer uses an addressing scheme called a port number. Port numbers identify applications and Application layer services that are the source and destination of data. Server programs generally...

Network Types

a. Local Area Network (LAN) / Local Area Network. A LAN is a network that is limited by the relative area small, generally limited by the environmental area such as a office in a building, or a school, and usually not distance of about one square kilometer. Some models of LAN configuration, one computer is usually on make a file server. Which is used to store software (software) that govern network activity, or as software that...

MICROSOFT SHELL - Command Prompt future

In certain cases, Windows is still lagging compared to Linux. The most obvious example is the lack of features compared to Windows scripting languages scripts Linux BASH, SH, or KSH.Windows batch file is too simple for an administrator. Scripting Host itself is considered too risky. With the Microsoft Shell (MSH), the developers in Redmond hopes will be significant change. Currently MSH (formerly known as Monad) has been circulating...
