Essays on Datagrams

INTRODUCTION

The protocols at the transport layer of the OSI reference model provides an end-to-end data delivery service for application processes to exchange messages over the Internet. Protocols operating in the Transport layer use the services of the Internet Protocol (IP) to deliver messages. Many protocols exist at his layer and one of the most important protocols at this layer is Transmission Control Protocol (TCP) for the delivery of data between the Application Layer and the Internet Layer. The shortcoming of IP to guarantee the delivery of datagrams is overcome by TCP by setting up a virtual circuit between the communicating ...

Network Protocols

A network protocol is a set of rules that manage the communication between two or more computers within a given network. This set of rules determine given characteristics of a given network, such as allowed physical topologies, access method, speed of data transfer and types of cabling.

Common network protocols include:

- FDDI - Token Ring - Ethernet - ATM (Asynchronous Transfer Mode) - Telnet (Telephone Network) - SSL (Secure Socket Layer) - FTP*SMTP (Simple Mail Transfer Protocol) - SFTP (Secure File Transfer Protocol) - HTTP (Hyper Text Transfer Protocol) - HTTPS (Secure Hyper Text Transfer ...

Remote access protocols

There are many remote access protocols that are used in Windows and, therefore, choosing a remote access protocol is a procedure that is important. The remote access protocol that will be selected will depend on the use of the protocols. When undertaking a plan to configure a remote access network environment, it is important to know what protocols the client, and the server will be using. This will determine the protocols that will be used for authentication, connectivity and encryption. There are two categories of protocols that are used for connectivity. These categories are dial-up and virtual private networking. Each of these categories ...

I have always been fascinated by computers and technology when my parents bought me a computer. I spent most of my time trying to figure out it how it operates by searching the internet for answers. At first I thought it was as simple as just clicking icons and programs, but through my newly developed interest in technology I got to understand how complex technology is. With rapid technological advancements, I learned that it was impossible to learn all the complex elements that enable computers work. However, I developed an interest in computer networks. The fact that computers can communicate ...

Purpose and function of TCP/IP

The Transmission Control Protocol/Internet Protocol (TCP/IP) suite is a set of protocols that describe the functions necessary for sending data over a network. These protocols define acceptable data formats and standards for passing messages, handling errors and for communication. The suite provides the foundation for many crucial services such as file transfer, electronic mail, remote login, network monitoring among others[ CITATION Tan03 \l 1033 ]. It is designed to separate the functions of the various facets of data transmission. International open standards make is possible for different companies to write software that is compatible. When data is ...
