To the untrained eye, HTTP syntax may look rather complicated, but it is actually simple. There is a series of request messages and response messages between the server and client where request methods are sent and status codes are returned. A typical exchange has a client send a get method requesting content, specifying the location, and stating which version HTTP the client is supporting. The response from the server will return with what HTTP the server supports and a response code, which depends on where the request is reasonable, or in other words if it has the content the client requests.
"URL is an acronym for Uniform Resource Locator, and is used to determine addresses on the World Wide Web. URL generally affirmed by sounding out every letter yet, in a few quarters, pronounced "Earl" - is an exclusive address for a file that is approachable on the Internet. An easy way out to get to a Web site is to enter the URL of its home page file in your Web browser 's address line. However, any file inside that Web site can likewise be indicated with a URL. Such a file may be any Web (HTML) page other than the home page, an image file, or a program such as a typical gateway interface application or Java applet. The URL includes the name of the protocol to be utilized to obtain the file resource, a domain name that recognizes a typical computer on the Internet, and a pathname, a hierarchical description that dictates the location of a file in that computer.
A URL (Universal Resource Locator) is defined, according to contests.about.com, as the “other name for a web address or the text that a web visitor types into their internet browser when visiting a website.” . Contests.about.com, states further that once the web visitor provides the browser with a URL, it can find where to go in locating the web page that wants to be visited. The web page symbolizes the “resource” that the browser is trying to locate with a URL. Webopedia.com, defines a URL as the “global address of available documents and other resources on the world wide web.” . Webopedia.com elaborates further that the first part of a URL is known as a protocol identifier and it indicates what protocol to use, and the second part is the resource name and it specifies the IP address or the domain name where the resource is located. A URL is the address of a webpage or file on the internet. For example, the URL of amazon website is “http://amazon.com”. The address of Amazon’s coupon page is
TCP/IP stands for transmission control protocol/ internet protocol. TCP/IP is responsible for how devices like computers should be connected over the internet and how data should be transmitted from one computer to another. The IP essentially functions by exchanging set of information which is called packets. Packets are short structures of bytes which contains of headers and body. The body only contains the application data. The headers keep on sending the information back on forth until the data is sent to the right destination, the packets can usually send in the wrong order this means that the data was crashed by the firewall or data was destroyed while sending information.TCP is the transmission communication protocol which delivers packets to the accurate to destination.
The application layer: this layer allows different applications to communicate with each other’s. In order to exchange different data over the network connection, the protocols included in this layer set up the standards such as DNS, HTTP, FTP. The data coded in this layer will be encapsulated to transport layer for further packing.
The basic components of a URL makes it easier to identify from where the web page originates and who is responsible for the information on the page. Every URL has basic parts; the Protocol, the server name, the path, the query and the parameter. The protocol identifies the method through which the resource is transmitted on the internet. It is a set of rules a web server and a browser use to connect and comprehend each other. The most commonly used protocol is http which stands for Hypertext Transfer Protocol. The server name generally recognizes which organization, office or
The two TCP/IP transport layer protocols (TCP and UDP), are very crucial for the smooth operation of network services for both the computer applications and application layer protocols such as HTTP, FTP, SMTP and Telnet. These two transport layer protocols TCP and UDP execute these services via the employment of IP. They use IP in the efficient routing of packets to their respective destination networks (Steinke,2001).The TCP is further noted by Steinke (2001) to be responsible for the provision of a reliable and yet connection-oriented byte-stream packet delivery while its counterpart UDP is noted to be responsible for the provision of a connectionless but rather unreliable packet delivery. In this paper we explain the work of the two TCP/IP transport layer protocols (TCP and UDP). In addition, describe how TCP and UDP manage key functions such as reliability, port addressing, and segmentation.
URL (Uniform Resource Locator) is nothing more than the address of a known distinctive resource on the Web. A URL is a collection of various parts, some obligatory and others voluntary. First is the protocol and it indicates which protocol the browser have to use. The Web necessitates one of these two, however browsers also know how to lever other protocols such as mailto: or ftp. It points to which Web server is being called for. On the other hand, it is probable to honestly use an IP address, because it is less expedient and is not frequently used on the Web. Second segment is the port which specifies the practical door used as a way in for the resources on the web server and application. Third segment is the anchor which signifies a
FTP is short for File Transport Protocol a program that allows users and computers to send and receive large portions of data through a private or public network. It can also be used to send configuration files to network devices, such as switches and routers.
