employs continuous transmission of an electromagnetic wave form that varies in frequency and amplitude. A digital communication system uses discontinuous transmission that may vary in frequency, amplitude and/or phase to represent binary data. Simplex and Duplex: A communications network can provide many types of service. The most basic type of service is known as simplex. This service provides one-way communication. Examples of this type of service are TV distribution, and the transmission of burglar alarm
User Datagram Protocol is one of the transport layer protocol which offers limited amount of service when messages are exchanged between hosts. Data is further subdivided into data grams for transmission across the hosts. UDP does not allow retransmission of the damaged or lost packets and there is no acknowledgement for the packet which has been sent. DGRAM_SOCK is the type of socket used for transmission of data. Unlike TCP, however, UDP does not provide the service of dividing a message into packets
method of communication between themselves in order to relay the information to the correct destination. The communication protocols are a set of standards that tell different hardware and software how to transfer data elements between them. When working with the OSI model, the protocols will govern communication between entities on the same reference model layer. Network protocols include mechanisms for devices to identify and make connections with each other, as well as formatting rules that specify
Instructor – Dr. Yipeng Liu LAB 1 – TCP: TRANSMISSION CONTROL PROTOCOL Submitted by: Submission Date: 09-25-2015 Divya Malika Vandana Z1776136 Divya Reddy Chandupatla Z1768598 SUMMARY In this lab, we used Transmission Control Protocol (TCP) which is a connection oriented protocol, to demonstrate congestion control algorithms. As the name itself describes, these algorithms are used to avoid network
Introduction: Congestion Control Transfer Protocol (CCTP) is an advanced, stable message-determined transport layer protocol. CCTP lies in between the Network layer and Application layer and serves as the agent between network operation and application programs. Figure below shows the IP suite associated with the relationship of CCTP protocol with others. This protocol blends the prominent characteristics of TCP, UDP and SCTP.

ended.To make a resource reservation the Resource Reservation Protocol communicates with two local decision modules -Admission Control : Admission control checks whether the node has available resources that can meet the requirements -Policy Control : Policy control determines whether the user has the permission to reserve the resource. If the admission control check and the policy control check fails the Resource Reservation Protocol gives an error notification to the process which initiated the
TCP/IP Name Affiliation Date TCP/IP Introduction TCP stands for Transmission control protocol while IP stands for Internet protocol. They are merged together to form the Internet protocol suit which is a model for networking which consists of communication protocols which are used for internet and other similar networks. This protocol suite was designed and developed by the Department of Defense (DoD). It was developed in order to connect different networks which were designed by different

So, voice packets can be given higher priority over normal data packets. Another method is weighted fair queuing. Here, a minimum amount of bandwidth is allocated to certain traffic, in this case, voice. This can be done using the Resource Reservation Protocol (RSVP). It's a common feature in
TCP/IP is a network model which enables the communication across the Internet. The most fundamental protocol on which the Internet is built. This is made up of the 2 common networking protocols, TCP, for Transmission Control Protocol, and IP, for Internet Protocol. TCP maintains and handles packet flow linking the systems and IP protocol has the ability to handle the routing of packets. However The TCP/IP stack consists of 5 layers first being application layer, the transport layer, then the network
TCP/IP Overview When designing networked applications one key protocol stands out as the foundation for making it possible. That protocol is TCP/IP. There are many protocols out there that allow two applications to communicate. What makes TCP/IP a nice protocol is that it allows applications on two physically separate computers to talk. What makes TCP/IP great is that it can do with two computers across a room or across the world. In this paper I will show you how TCP/IP allows a wide array of computer
for Electronic Mail, a software application based on communications to transmit messages over the Internet as a communication network. The E-mail becomes the most popular and frequently used application because of the reasons of easily message transmission to the receiver even though the distance location of the sender and receiver within a thousand miles. Most of e-mail systems consist of an elementary text editor for composing messages, but many allow users to edit the messages using any editor
File Transfer Protocol (FTP) is an application layer protocol, which has the primary function of transferring data files between computers (Clark 2003). The protocol specification was originally developed in the early 1970s, and was published as RFC 114 in April 1971, by Abhay Bhushan. This occurred even before the Internet Protocol Suite – commonly known as TCP/IP or Transmission Control Protocol (TCP) and the Internet Protocol (IP) – was even established (Kozierok 2005). The protocol specification
7. How do local area networks (LANs) differ from metropolitan area networks (MANs), wide area networks (WANs), and backbone networks (BNs)? Local Area Network as defined in our textbook is a “group of computers located in the same general area,” (Fitzgerald & Dennis, 2012. p13). LANs is a type of network usually implemented within an office, school or home environment where group of computers are located in proximity with each other or in a small geographic area. Thus, client computers are interconnected
can speak the same language. Im going to overview how TCP/IP works into the entire system. Keeping in mind the OSI reference model (Fig. 1). While TCP and/or UDP are running at the Transport Layer IP is running at the Session Layer. The IP protocol handles fragmentation of packets. Fragmentation is essential, because some networks allow a very large packet size, and others do not packets sometimes must be fragmented. The presentation layer is where the TCP/IP "languages" are used such

SLIP is a TCP/IP protocol used for communication between two machines that are previously configured for communication with each other. For example, your Internet server provider may provide you with a SLIP connection so that the provider's server can respond to your requests, pass them on to the Internet, and forward your requested Internet responses back to you. A better service is provided by the Point-to-Point Protocol (PPP). Point-to-Point Protocol is a protocol for communication between two
communication protocols which would allow networked computers to communicate transparently across multiple, linked packet networks. This was called the Internetting project and the system of networks which emerged from the research was known as the "Internet." The system of protocols which was developed over the course of this research effort became known as the TCP/IP Protocol Suite, after the two initial protocols developed: Transmission Control Protocol (TCP) and Internet Protocol (IP).

1.0 INTRODUCTION For mini project of this subject, I choose to analyze performance management of different Wi-Fi based on context Wi-Fi service provided in my house area which is SriPuteri WifiNet. To analyze the performance management, I have to identify the problem statement, scope and method to use. In Local Area Network (LAN), although multiple device such as PC, laptop, mobile phone and many more can connected to Wi-Fi but as the increasing of device used, the network can become slower because
SCADA, or often referred as Process Control Systems (PCS) is interpreted as an overall collection of control systems that measures, reports, and changes processes SCADA is the acronym of Supervisory Control and Data Acquisition, which is a communication technology scheme for collecting data from distant facilities and also controlling them on control systems. In the beginning SCADA system was locally introduced, and it has been applied to larger and wide-area systems as the information technology
TOPIC:IP ADDRESS Cyber Law & Information Security The address of a computer on the Internet is commonly referred to as the IP Address (Internet Protocol). It's a 32 bit (4 bytes) number normally written as follows: xxx.xxx.xxx.xxx Since a byte can represent any number from zero to 255, the least and the maximum IP address possible are: 0.0.0.0 to 255.255.255.255 Understanding IP Addresses Understanding IP Addressing is necessary, since all applications on the Internet generate logs
