Essays on Data Communication

Amazon is an online company which thrives on its ability to collaborate and work well with other technological innovations that can enhance its performance and popularity. The creation of cloud services after Amazon began to lease some of its capacity is proof of the company’s collaborative ability. After the holiday season when Amazon was left with less infrastructure capacity, the company would give some of its capacity to others. On flexible sharing terms of internet space, Amazon helped out other companies which were just beginning to thrive in the cyber world and thereby it revealed that the company ...

Communication System

The key elements of a data communication system are the source, the transmitter, the transmission system, the receiver and the destination. The source will be used in the generation of the data to be transmitted. The transmitter has a purpose of transforming and encoding the data into signals that can be transmittable for example the transformation from a digital bit stream to the corresponding analogue signal. The transmission system serves the purpose of carrying the data and it can be in terms of a transmission line or a complex network connecting the source and the destination. The receiver will ...

The world is experiencing a new dawn of the Internet of things (IoT). The IoT can also be referred to as Internet of objects because it deals with the combination of different components. The objects are interconnected in a manner to have ubiquitous intelligence. The ubiquity of the Internet increases every day because the integration of objects increases as well, which eventually leads to a distribution of objects that assist human beings in communication. It also communicates with other devices to send back a viable feedback that assists people in particular duties that are undertaken daily. The IoT is ...

Overview of IEEE 802.1 Higher Layer LAN Protocols Working Group

The IEEE 802.1 Working Group is responsible for the development of standards and recommended methods in the areas of 802 LAN/MAN architecture, internetworking among 802 LANs, MANs and other wide area networks, 802 Security, 802 overall network management, and protocol layers above the MAC & LLC layers (Ieee802.org, 2016). Each Working Group comprises of charters which have some stated goals and tasks .These usually permanent and exist until they accomplish their goals. Currently, IEEE 802.1 Working Group comprises of following four subgroups:

Security: One of the projects is development of MAC security key agreement protocol (MKA) extensions (ADP). The group ...

There are a number of benefits that are derived from the internet most notably the transformation of various business organizations. Through the internet enabled procurement systems, production, customer service and procurement costs can relatively be reduced as a result of stiff competition and expanded market niche. The cost can further be reduced by shifting sales and information to even lower-cost channels. The internet drastically accelerates speed-to-market by considerably reducing the time required to transmit, receive and process various business communications like shipping notifications and purchase order.

On the other hand, data communication can be defined as a transfer of digital information ...

Definition of the project Objectives:

The objective of this project is to design a microcontroller based system to obtain the information regarding the temperature of a remote place. It is usually inconvenient getting the readings of temperature, pressure etc. from the places that are very distant. But the advancement in technology has made this task possible. Our main objective is to design such a system. For this we will use the infrastructure of the existing mobile network, which is based on GPRS technique. This project investigates on creating very low cost device which can be adapted to many different applications using some very basic programming, and joining ...

The Name of the Class (Course)

The Name of the School (University) The City and State Introduction The emergence of Windows server 2012 has revolutionized the entire network environment, because it has made easy the process of installation of Operating Systems (OS), which was initially a very cumbersome task for computer users across the globe (Lavapie, 2012). It has simplified the process by eliminating activities, which used to be done before the actual installation of the OS, for example, configuration of CMS, formatting and partitioning of hard drives. Installation of an OS involved the use of DVDs and CDs, and there would occur ...

A security risk within the context of data communication is described as any action of inaction that poses a threat to the integrity and security of data communicated between a sender and a receiver. Security threats in communication are all too real and pervasive and mischief makers always try to exploit the vulnerabilities of system design and architecture in order to perpetrate illegal activities. As the waves of the threats increase, different methods and techniques are also deployed in order to guarantee the security and integrity of data exchange. Some of the techniques involve the protection of networks from unwanted data traffic ...

Internet Protocol Security

IPsec is the short abbreviation for Internet Protocol Security which is referred to as the protocol suite used in securing the Internet Protocol (IP) network communications through encrypting and validating each IP packet (data sent over the internet) of a communication session. Internet Protocol security comprises procedures and protocols used in establishing a reciprocated authentication or verification procedure between artificially intelligent agents at the commencement of the interconnection period and the intercession of cryptographic keys to be used by the network user during the given time lease period (Black, 2000). Internet Protocol security can be used in guarding data and ...

Introduction

Networking has been enhanced with the introduction of techniques to enhance the techniques that have been used in the networks. The process of communication in various channels undergoes a long process. This paper will focus on the multiplexing and how it enhances communication. It has a role it plays in networking (Abrams, 2004). The term multiplexing as refers to the process of converting many data communication lines or signals into a single data communication line or signal for transmission (www.computing.net) the main aim is to optimize utilization of the transmission channels given that several users share the same channel (Stallings, 2009). ...

Non-repudiation applied in digital security has cryptological implications. It is basically a service seeking to prove the originality and integrity of data. With a high assurance of data, it can be asserted that the said data is genuine. Asymmetric cryptography allows for proof of the said data without the verification or the consent of the original author. This report explains why the forms of non repudiation are important to information assurance. It also identifies and describes the trust or security domain boundaries that may apply to a personal computer in a business environment. There are two forms of non repudiation: non repudiation ...
