Essays on UDP

Interprocess communication (IPC) is a group of programming interfaces which enable a software developer or programmer to coordinate different tasks and activities among different program operations which execute simultaneously in the operating system. IPC enables a program to handle many user requests at the same time. An user request results in execution of multiple processes in the operating system. The processes must communicate with one other to carry out their tasks. The interfaces of IPC aids in communication,data exchange among the different processes. There are advantages and disadvantages present in every method of IPC. A single program can ...

Information Security Threats

Introduction Information is one of the most important assets for many organizations, as it acts as a differentiator and provides a competitive advantage. Loss of information such as patent information, proprietary processes, or trade secrets could prove to be very detrimental to a business. While there are many threats to the information security, this report focuses on three of them, which are 1) Denial of service, 2) Privilege escalation, and 3) Backdoor. This report provides measures that address, block, or removes these threats. Information about tools, products, or services that mitigate these threats is provided in the report as ...

Summary: This article was about Information security governance and Risk Management in CISSP domain. In the article some basic guiding principles for the security are highlighted, the security's fundamental principles revolve around the CIA i.e. confidentiality, integrity and availability. Confidentiality confirms that the data is confidential through personal identifying information, integrity ensures the accuracy of the data and it is not modified by anyone else and finally availability ensures that whenever the data is needed, it is available i.e. no DOS attacks or any other attacks stops the access of the data. The risk management talks about the analysis ...

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 ...

Question One

The two factors for delay include; propagation and serialization. Propagation is the amount of time taken before data can travel at the speed of light from the data source to the destination. Serialization is the process of converting data stored from bytes into a stream of bits that can be transmitted over the networks.

Question Two

One of the causes of packet jitter is the congestion in the IP network. The other reasons include route changes, and timing drift.

Question Three

Making use of a jitter buffer will help reduce the delays in the packet delivery. The applications consuming the packets in the ...

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 ...

Network Address Analysis (NAT)

Introduction

Network Address Analysis (NAT) is an internet standard that facilitates a local area network to use one set of IP addresses for internal traffic and a second set of addresses for external traffic. A NAT maps an entire network to a single IP address. It is very necessary when the number of IP addresses assigned by the ISP is less than the total number of computers that you are willing to use for accessing the internet. NAT allows one to use the reserved address blocks which are described RFC 1918 – Address Allocation for Private Internets. NAT works by inquiring both the ...
