Describe The Advantages And Disadvantages Of A Computer System
A network is a group of two or more computer systems linked together. A computer network or data network is a telecommunications network which allows computers to exchange data. In computer networks, networked computing devices pass data to each other along network links for data connections. The connections between nodes are established using either cable media or wireless media. Network computer devices that originate, route and terminate the data are called network nodes. Nodes can include hosts such as personal computers, phones, servers as well as networking hardware. Two such devices are said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other. Computer networks differ in the transmission media used to carry their signals, the communications protocols to organize network traffic, the network 's size, topology and organizational intent. In most cases, communications protocols are layered on working use either other more specific or more general communications protocols, except for the physical layer that directly deals with the transmission media. (Cory Janssen) Modern networks almost always have one or more servers which allows centralized management for users and for network resources to which they have access. User credentials on a privately-owned and operated network may be as simple as a user name and password, but with ever-increasing attention to computing

The principle objective of Chubby is to provide reliability and availability where as providing performance and storage capacity are considered to be optional goals. Before Chubby Google was using ad-hoc for elections, Chubby improved the availability of systems and reduced manual assistance at the time of failure. Chubby cells usually consist of chubby files, directories and servers, which are also known as replicas. These replicas to select the master use a consensus protocol.

The first classification is based on the place where ID systems can be placed and the second one is based on analysis of the technique used. These ID systems can be classified into three main groups starting with Host Based Intrusion Detection System (HIPS), then Network Behavior Analysis (NBA), Network Based Intrusion Detection System (NIPS), and Wireless Intrusion Prevention System (WIPS). The WIPS it analysis the traffic of wireless network, NBA examines traffic to identify threats that generate unusual traffic flow, HIPS monitor single host for suspicious activity, NIPS it analyzes the traffic of entire network.

572 Words | 3 PagesNot only will these innovations improve network strength, but possibly the speeds at which a client can access information from an application server. This has the potential to make cloud computing even more prevalent than it already is today because it would become easier to keep up with mass traffic to the servers. Large server banks would be able to be downsized slightly compared to their current sizes. The computer science techniques used in created Marple show that it is possible to even make an old process useful in modern applications. The hardware of Marple is also programmable making it extremely useful for any network engineers because they will be able to write custom software for Marple-based

UDP amplification DNS: DNS is attacks in which an attacker delivers traffic to the victim of their attack by reflecting it off of a third party so that the origin of the attack is concealed from the victim. It is substantially easier for an attacker to spoof their source address with UDP. Virtual machine:

598 Words | 3 PagesUnderstanding networking is a fundamental part of configuring complex environments on the internet. This has implications when trying to communicate between servers efficiently, developing secure network policies, and keeping your nodes organized. Every location or device on a network must be addressable. This is simply a term that means that it can be reached by referencing its designation under a predefined system of addresses. In the normal TCP/IP model of network layering, this is handled on a few different layers, but usually, when we refer to an address on a network, we are talking about an IP address.

410 Words | 2 PagesWith widespread use of internet services, the network scale is expanding on daily basis and as the network scale increases so will the scale of security threats which can be applied to system connected to the network. Viruses and Intrusions are amongst most common threats that affects computer systems. Virus attacks can be controlled by proper antivirus installation and by keeping the antivirus up to date. Whereas any unauthorized access in the computer system by an intruder can be termed as Intrusion and controlled by IDS. Intruders can be grouped into two major categories which are external and internal Intruders.

The proxy provides the resource either by connecting to the specific server or by serving it from a cache. Sometimes, the proxy may alter the client's request or the server's response for numerous purposes. Routers are the devices that join together the various different networks that together make up the Internet. In a network, routers are sophisticated switched hubs.
