Essays on Transmission Control Protocol

Determine the importance of understanding the Transmission Control Protocol / Internet Protocol (TCP / IP) and Open Systems Interconnection (OSI) Reference models from the perspective of an ethical hacker. Transmission Control Protocol/Internet Protocol reference model govern communications across different computers on the internet. The user gets to understand the process of packaging, sending, and receiving communication. The main TCP/IP protocols include HTTPS, HTTP, and FTP. On the other hand, the Open Systems Interconnection reference model plays the role of characterizing and standardizing communication between two computers on the internet. OSI helps guide vendors and network developers to ensure the ...

Abstract

The Cloud and Grid computation systems are different computation services or platforms that can help in different tasks. Cloud computing started in late 1990s. It is the form of TCP/IP (Transmission Control Protocol/Internet Protocol) based on advanced development and integration of computer technologies such as huge memory, fast microprocessor, reliable system architecture, and high-speed network. Cloud computing are helpful in solving Internet-level computation problems, which are somewhat different from those of Grid computing. On the other hand, Grids started working in the mid 1990s to compute the large-scale problems with the help of network based resource-sharing commodity machines. Such ...

Key considerations behind establishing trust relationships between the two domains

Trust between domains refers to the relationship between domains that enables a domain controller in one domain to authenticate the users in another domain (Gibson, 2001). All domain trust relationships have two domains: the trusted domain and the trusting domain. The types of trust include Forest, Realm, External, and Shortcut (Gibson, 2001). For the purposes of this paper on Quality Corporation (Quality.ad) and Crescent Inc. (Crescent.ad), these considerations regard the Forest Type domains. There are several considerations in the establishment of trust relationships between domains. The first is the characterization of the trust into one of these four categories; ...

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 ...

1. The structure of the internet The internet is an international network of computers and other devices for the purpose of sharing resources. It is a global interconnection of millions of computers all across the world using a standardized protocol (Transmission Control Protocol / Internet Protocol, TCP/IP) to facilitate interconnection of the computers. The internet does not have a structure in particular but the networks and devices used found on the internet conform to a standard as set by the International Standards Organization (ISO). 2. Internet domains Internet domains are managed by a Domain Name Service (DNS). DNS is a hierarchical naming ...

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 ...

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 ...

The key aspect of e-business is its focus on digitization of business operations from a traditional narrow range perspective to a technological wide range perspective that proves significant to businesses that rely on the internet for their functioning and success. Fundamentally, e-business is a broader concept and it is concerned with using the internet and related technologies to integrate and redesign an organization’s internal activities, processes and external relations, and create new ways of working that are significantly different from, and very often far superior to, what was possible or conceivable some years back. Moreover, interest in e-business has been driven ...
