Computer Networks Essay

Computer Network Design When opening a new business, the computer network design needs to be designed to meet the needs of the business and protect the business assets at the same time. There are three aspects to the designing of the network system, which include technology and software, people and the human aspect, and the combination of the two. The technology and software are the core components of the actual system that determine how it will operate and protect the assets. The people and

What field in an IP datagram can be used to indicate that a packet should be routed before any other packets? b. the Differentiated Services field 4. What happens to an IP datagram

There are many things to consider when designing a computer network –such as costs of components, software and labor; communication, cohesion, expandability and many others. However, the end goal in such an enterprise is to have a fully functional, harmonious, and cohesive tiered system where duties and actions are divided, and delineated accordingly. One of the major network architectures used to facilitate this process is known as the TCP/IP Protocol Suite. The TCP/IP Protocol Suite was designed

Networks can be broadly classified into two types: 1. Wired networks 2. Wireless networks Some of the drawbacks of the wired networks had brought the “wireless networks” into the picture. Wireless operations permit services, such as long-range communications, that are impossible or impractical to implement with the use of wires. The term is commonly used in the telecommunications industry to refer to telecommunications systems (e.g. radio transmitters and receivers, remote controls etc.) which use

Introduction Generally, computer network security systems and structures considered robust are preceded not by software and hardware but by careful planning. A typical computer network security plan must take into consideration a wide range of security risks and vulnerabilities and from that, develop a road map to reduce such exposure. Given the need to protect the integrity and confidentiality of data as well as other system quality attributes, the need to mitigate exposure cannot be overstated

Many modern day commercial firms have a system of computer based network to track the activities of their employees at the workplace. Employers can track the emailing and browsing history alongside any other activity carried out by an employee using computers even if they clear the history (Reynolds, 2011). Companies are on the run to come up with strict policies to track the use of the computers among employees. Some firms argue that computer based monitoring is important although it is quite expensive

Malicious wares Worms A computer worm is a program that self-propagates across a network exploiting security or policy flaws in widely-used services. The first computer worm widely spread in 1988. Typically, worm can be divided to different class based on different factors. Such as target discovery, carrier, activation, payloads, and attackers. There are some successful multi-modal worms; however it is still based on the specific method mentioned above. Doesn’t like other malwares, most of worms

INTRODUCTION As networks and computer systems become universal and exposed, security threats and risks continue to grow more rapidly. This causes enormous threats; therefore, Security specialists and experts are continuously trying to find solutions for these kinds of threats through different methods like attack signatures and looking for methods to prevent them. Nevertheless, as solutions are formed, new types of threats emerge, for example spam mails, spywares, worms and Trojans just to mention

Introduction The Proliferation and advances in computer network have led to increase Distributed database system In Distributed Database Different user are connected for accessing the data. In distributed database the data from the single local computer can be transferred or distributed on various computer connected at the same physical location. The Data from the database can be distributed to the multiple physical loacation. It is a powerful technology with great potential to help companies
