IT Risk Management free essay sample
You have been asked to help upgrade the LAN at a very successful ABC firm with five departments in one building and a total of 560 employees. Although the firmââ¬â¢s employees understand accounting, they havenââ¬â¢t spent much time improving their network. Currently, it runs 10Base-T Ethernet and relies on 35 hubs to connect every user workstation to the network. Most of these workstations were purchased within the past two years, when the firm experienced a growth spurt. The hubs are connected to the backbone via switches. The CPA firm wants to upgrade its LAN, but not at great cost. It also wants to ensure that it can easily expand its LAN in the future. It has already decided to use a version of Windows 2008 as its network operating system. What kind of LAN will you design for this company? Describe its physical and logical topologies, what access method it will use, and what Physical layer standard this access method should rely on. We will write a custom essay sample on IT Risk Management or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page What types of infrastructure upgrades are necessary to implement your suggested network? The ABC firm that has five departments in the building those all connected with LAN and total employees of 560, which currently runs 10Base-T Ethernet and relies on 35 hubs. These workstations were purchased in last two years, but they are experiencing slow network connectivity. Based on the current situation, they have decided to use Windows 2008 OS version. Though, this firm has a limited budget, where the firm bought some hardware and software. The IT world uses very high-grade equipments through which we can integrate and update the existing network. The below design shows the hubs which are upgraded by me to switches and these are much better than hubs. Each department has 112 employees and we got five departments, which are connected with one router. I recommend for this network that every department should have one printer which must be connected with the same network. Based on the size of the firm and for a higher growth in the near future, my recommendation to the firm is that it should have a secure, intelligent and much faster network, which leads to upgrade the current network. I have modified extended star topology that one router gets connected with the internet and also with all five departmentââ¬â¢s switches. Every department has 112 employees and we are using five switches for each department whereas one of the switches connects to main router and the rest of the switches connect with other router. This way we get 120 ports in each department in which we are providing printers that will connect to one of the switches of that department. Thus, we can bring 112 ports in use and the rest will be left safe for future expand without any exorbitant cost or moving a lot of equipments. We can add printer, fax, workstation, or other things as well in these ports. If the firm would have more employees or workstations, then the firm would add new switch connect all workstations to that switch which one connected with the same departmentââ¬â¢s switch. PHYSICAL TOPOLOGY: Physical topology means the physical design of a network including the devices, location and cable installation. It is the physical structure of the network. LOGICAL TOPOLOGY: Logical topology refers to how data is actually transferred in a network as opposed to its physical design. In general, physical topology relates to a core network whereas logical topology relates to basic network. The logical topology is the way that the signals act on the network media, or the way that the data passes through the network from one device to the next without regard to the physical interconnection of the devices. LAN ACCESS METHOD: Local area network (LAN) access methods, such as CSMA/CD in Ethernet, transfer data to and from connected computers on the network. These methods reference layers 1 and 2 of the OSI model. CSMA/CD: It is used with bus and some star topologies. It operates by contention; each terminal competes for access to the bus. A terminal wishing to transmit attempts this when the bus is quiet. Concurrently, received signals are monitored by this terminal to check for corruption resulting from collision with another transmission present at the same time. In the event of such a collision its effect at this terminal is enforced with the use of a jamming signal and all current transmissions are stopped. Repeated retransmissions are made, with designed in-delays to reduce the probability of further collisions, until successful transmission occurs. When carrying long data packets over short cables and with offered traffic of about 20% or less of maximum, the systems works extremely well. TDMA: It was originally devised for digital microwave and satellite communications systems. It is still used with many such systems as well as with some fiber optic systems. Fixed time slots are made available, regardless of whether they are actually used. The complete end-to-end bit sequences within each time slots are usually called a serial packet, each of which comprises source and destination address, data bits, control and status bits. The system is accessed through terminal stations and repeaters. Transmission is into an empty packet or packets and reception occurs via packet address recognition. A monitor station monitors the integrity of the system during normal operation and places framing bits around packets in the initializing process. WORKGROUP SWITCHES: Firm has the smallest of the switching hubs. They usually have between 8 and 12 ports per hub used to connect stations and the servers these stations need to access. If selecting this type of hub, this kind of hub not intelligent like switches and not reliable to secure either to ensure that firm for growth. Those hubs canââ¬â¢t be taking too much load thatââ¬â¢s why network is too slow. So see the future growth I decide to change hub to switches. DEPARTMENTAL SWITCHES In new design, there are switches connected to other department as that and main switch connecting with other department switches and server as well. DISADVANTAGE: Newly designed Ethernet a central connection point might be desirable for security or restricted access, but this is also a major disadvantage of a star topology if the central device fails, the whole network becomes disconnected. When a star network is expanded to include an additional networking device that is connected for the main networking device, it is called an extended star topology.

Humility and Humiliation
Humility and Humiliation Humility and Humiliation Humility and Humiliation By Maeve Maddox I heard a television interview subject express compassion for previously independent Gulf Coast fishermen whod had to go through the humility of accepting financial help. The word wanted in that context was humiliation, not humility. Wanting to see if it were a common error, I did a web search. Sure enough, I found more examples: â⬠¦each member of our family suffered humility and loss of face in public â⬠¦having to submit to the humility of having to ask for new shoes â⬠¦the humility of having to ask for so many payment options â⬠¦hope they never know the humility of having to ask for help. In some religious writing the words humility and humiliation may overlap, but in modern secular usage, the words have distinct meanings. humiliation: the act of humiliating or condition of being humiliated; abasement. humility: The quality of being humble or having a lowly opinion of oneself; meekness, lowliness: the opposite of pride or haughtiness. Humiliation is a bad thing. Its a painful emotion that we feel when weve been shamed. No one should be treated in such an unfeeling, bureaucratic way as to be humiliated. Humility is a good thing. It is a virtue that has become very rare in a culture that even goes so far as to begin sentences with me and myself. A humble person gives credit where its due. A humble person acknowledges others and respects their dignity, talents, and opinions. Humility is not weakness; its a spirit of self-examination that prevents one from becoming selfish and arrogant. The word humiliation applies to a negative state of debasement inflicted by persons or conditions outside oneself. Verbs that go with the word humility are not suffer or endure, but practice or cultivate. NOTE: One often sees the word humbleness, but it seems wasteful to use a -ness form when the distinctive abstract noun humility exists. Want to improve your English in five minutes a day?

Impact of Technology on Sales Essay Example | Topics and Well Written Essays - 750 words
Impact of Technology on Sales - Essay Example W. Pergault. The company spent $20 million upgrading its website but this change did not have a great impact on sales and profitability. Managers are not interested in website and online sales because they "don't earn any commission". On the other hand, customer did not like the new website because of "distracting graphics", "the bells and whistles" (Spiro et al 2004). Resistance comes from the customer since they are not the beneficiary of organizational changes. Some of the reasons for resistance to change are; excessive focus on cost, failure to recognize benefits, lack of organizational synchronization, and individual uncertainty denial and fear of loss. In order to improve the e-commerce plan, Celia Fiorni, the company president, should restructure current compensation system and reward those managers who use the website and sell products through the Internet. Also, Celia Fiorni should encourage and motivate sales representatives to use the Internet and sell products through the Internet. Training programs will help to improve skills and knowledge of employees and reduce resistance to change. Salespeople will accept the new initiative ensured in fair compensation and computer skills. Technology can create new design options for various processes because it can be used to challenge longstanding as assumptions about work arrangements that used to inhibit organizations. Good understanding of end-user needs by system developers is another important factor, as are mechanisms for communication with the business users of the system. Senior management sponsorship and commitment is another success factor, but dependent also on the existence of a champion. Technically, the requirements of the system change to include reliability and its delivery to users in a suitable form. This process of continual selection and rejection of potential projects contrasts strongly with the tendency in many companies towards early formal approval of information technology projects whose costs and benefits are assumed to be certain. The results from the research broadly confirm that the factors identified for technical innovation also apply to information systems projects. For G. W. Pergault, CRM plays a crucial role helping to improve customer service and meet customers' needs and expectations. "G. W. Pergault offers more than 500,000 different products, which can be overwhelming to sort through. Sutton believes that some of his reps may have trouble finding specific products on the website" (Spiro et al 2004). An established information technology infrastructure obviously helps provide a base for delivery as well as making it clearer when new hardware and system software will be needed. Personnel should be connected directly to the concept of CRM, an approach that stresses the importance of developing long-term partnerships with customers. In developing personal and relationship strategies on an international level, the representative is wise to take a step back and understand how CRM strategies will likely fit in the environment. CRM requires an organization to first develop a transformation system that
