Advantages And Disadvantages Of Remote Working System Computer Science Essay

Advantages And Disadvantages Of Remote Working System Computer Science Essay Introduction The following report will be based on providing potential requirements of the basic scenario and a through explanation of advantages and disadvantages of updating the current network of the EERP Company. By analysing the key requirements it is clearly explained that the EERP is having two major employee classes as senior staff and junior staff. Junior staff works in the office which mean that they worked on fixed places. This will result them to have personal computers with LAN (Local Area Network) connectivity. Depending on the budget this can vary up to a wireless network by implementing wireless interfacing cards to their personal computers and having WIFI zones on the working area. Senior staff on the other hand, they work in their homes. From their they should be able to do various kind of functionalities E.g. deliver companys message via ProwerPoint presentations, compile, print documents, perform quires on existing customer records, send and receive email and complete sales orders. These functionalities should be done online or through the WIFI network at the company. It is clarified that the management has decided to equip the senior staff with a mixture of wireless enabled portable notebook PCs, printers and Personal Digital Assistants (PDAs) to get the maximum benefits out of their senior staff. To achieve these desired functionalities it is a must to implement a Virtual Private Network (VPN) between the senior staff and the Office network of the office. This will result them to connect their office even though they are remotely connected. They will be able to perform same kind of functionality which they perform in their office environment. When they work in the office they can connect to the WIFI network without connecting to the VPN. This network architecture will provide the senior member to be connected on their office network every time whenever they want. When it comes to wireless connectivity or VPN, security is a must. It is important to implement necessary security methods and protocols to connect any of the networks. With respect to the following requirements no of WIFI and VPN users should me defined and should be expandable with the growth of the company. Depending on the budget, suitable VPN provider should be selected. With the basic understanding of the key requirements it will be possible to prepare a network system with remote networking functionality. Advantages and Disadvantages of having remote working system Pros, It will be easier to implement and maintain. High reliability and availability. Network cabling will be reduced. Employees can stand on their work place dynamically without staying on one location Can easily configure the security of the network. Can easily divide departments as blocks of network access points. Expansion of the network will be easier than a Traditional wired LAN. Cons, Network connectivity will be lower than a wired LAN. VPN implementation will be expensive. Company should be facing a higher security threat when implementing a VPN. In order to enhance the security, firewalls and other third party tools have to be purchased. Employees should be well trained to use VPNs and wireless networks to avoid any sort of interruptions. Failure of a VPN will result some employees to not to cooperate with the company until it is fixed. Benefits to the company This system will allow employees to work interactively without any disruption. Employees who work on the office will have the WIFI connectivity. This means that they can work on their office desk as well as when they are not. They might be interacting with the customers even so they can connect with the network. They can share information, print documents and can query the information database. This will result interactive and efficient communication with their customers. Senior staff on the other hand can work in home as they are in the office. Because of the VPN they will gain almost all of the network capabilities as they are in the office. Email services, document sharing, print documents and even online presentation facilities can be provided. When they visit the office they can connect to the wireless network using their wireless enabled notebooks and PDAs. As a result they can have almost the same functionalities.

A router is connected to at least two networks, commonly two LANs or WANs or a LAN and its ISPs network. Routers are located at gateways, the places where two or more networks connect, and are the critical device that keeps data flowing between networks and keeps the networks connected to the Internet. When data is sent between locations on one network or from one network to a second network the data is always seen and directed to the correct location by the router. The router accomplishes this by using headers and forwarding tables to determine the best path for forwarding the data packets, and they also use protocols such as ICMP to communicate with each other and configure the best route between any two hosts. Network Interfacing Card A network interface card, more commonly referred to as a NIC, is a device that allows computers to be joined together in a LAN, or local area network. Networked computers communicate with each other using a given protocol or agreed-upon language for transmitting data packets between the different machines, known as nodes. The network interface card acts as the liaison for the machine to both send and receive data on the LAN. The most common language or protocol for LANs is Ethernet, sometimes referred to as IEEE 802.3. A lesser-used protocol is Token Ring. When building a LAN, a network interface card must be installed in each computer on the network and all NICs in the network must be of the same architecture. For example, all must either be Ethernet cards, Token Ring cards, or an alternate technology. WIFI Cards A wireless network adapter allows a computing device to join a wireless LAN. Wireless network adapters contain a built-in radio transmitter and receiver. Each adapter supports one or more of the 802.11a, 802.11b, or 802.11g Wi-Fi standards. Wireless network adapters also exist in several different form factors. Traditional PCIwireless adapters are add-in cards designed for installation inside a desktop computer having a PCI bus. USB wireless adapters connect to the external USB port of a computer. Finally, so-called PC Card or PCMCIA wireless adapters insert into a narrow open bay on a notebook computer. One example of a PC Card wireless adapter, the Linksys WPC54G (compare prices) is shown above. Each type of wireless network adapter is small, generally less than 6 inches (0.15 m) long. Each provides equivalent wireless capability according to the Wi-Fi standard it supports. Some notebook computers are now manufactured with bulit-in wireless networking. Small chips inside the computer provide the equivalent functions of a network adapter. These computers obviously do not require separate installation of a separate wireless network adapter.

Sexuality of Men and Women: A Comparison

The perceived views of men s and women s sexuality have been the subject of great speculation and conflict. Although great strides have been made over the years in the sexual â€Å"revolution†, the basic views of male and female sexuality have remained the same. Throughout history the ideas of proper sexuality for men and women have changed little. Men have always been portrayed as the aggressive pursuer of a woman’s sexual favors. Women, in turn, have been required by society to diligently preserve their honor outside of the marital bed. Andrew Marvell’s â€Å"To His Coy Mistress† offers a good example of the game-like behavior that has become almost expected of a man and woman in society. The narrator beseeches his Lady to â€Å"sport us while we may like amorous birds of prey†. The Lady on the other hand, flirts casually and spurns the narrator’s advances. Women are praised highly for their virtue and honor in keeping their virginity for the institution of marriage. Even though it is perfectly acceptable for a man to attempt for and even acquire the sexual favors of a woman it is a social sin and in some areas a crime for a woman to succumb to her sexual desires outside of marriage. In Nathaniel Hawthorne’s â€Å"The Scarlet Letter†, Hester Prynne is ostracized by her community for having an extra-marital affair. Her punishment condemns her for her adultery and assures her a lifetime of humiliation. Many societies have gone through great lengths over the centuries to ensure fidelity or virginity in women. In the Middle Ages, women were often forced to wear chastity belts to ensure their virtue was kept intact while men were away at war or some other manly undertaking. In some countries, women are forced to cover every inch of their bodies in an effort to avoid the advances of other men. The narrator in Amy Lowells Patterns speaks of her passion that wars against the stiff brocade of her dress, the very heavy and unrevealing style of the era in which the poem is set. She laments the death of her betrothed as they were to be wed in a month and, as she felt bound by the dress, he was to have freed her from it. This poem also illustrates how the narrator, as many women in the past, did not consider it proper to succumb to her passions before marriage. Men on the other hand have often been revered for their sexual prowess. Kings often kept concubines, or mistresses. In some countries, it is acceptable for a man to have many wives. Sexual conquest has become almost a gauge by which manhood is tested. Men are often bombarded by peer pressure to become sexually active at an early age. Seen as a rite of passage by many men, they begin their pursuit of women before they are even capable of reproduction. In Stevie Smith s The Frog Prince, the narrator speaks of his being happy the way he is but he feels that it is required of him to have a girl. Changing times have allowed people to become a little more open in expressing their sexuality. However, more often than not, most men and women tend to conform themselves to expectations that remain the same even in today s society.

Nursing Home vs. Home Health Care Essay

INTRODUCTION Either young or old, we love our family members dearly, and disabilities does not focus on a specific age group. We would love to feel assured that they are being taken care of the best way possible. As we all know, time does not allow us to take care of them ourselves, with business to tend to of our own, it makes it almost impossible. There are a few options to assist with this matter, but making the best choice is always in our best of interests. NURSING HOMES Nursing homes are facilities that provide high levels of care assisting elders and even young people that are temporarily or permanently disabled. There are several options that you can refer to for payment method. Medicare is an option. Medicare is a national social insurance program, administered  by the U.S. Federal government since 1966, it is currently using about 30 private insurance companies across the United States. You can also pay through your private insurance company, as well as out of pocket. Within a nursing home facility, they will be assisted with all of their ADLs. (Activities of Daily Living is a term used in healthcare to refer to daily self-care activities within an individual place of residence, in outdoor environments or both.) In this facility, they will interact with their peers, medical professionals, as well as others when visiting. They will have continuous care around the clock including routine vital signs. Vital signs includes the blood pressure, temp erature, heart rate and respirations. With the option of being able to choose a nursing home, there are a few factors in which you might need to consider. One factor is the ratio of CNA’s (Certified Nursing Assistant) to the residents, the ratio might not match the entire time accordingly to state requirements. According to Abbasi and Rudman, medical literature has continued to identify many clinical problems occurring within nursing homes. With this being said, there is a possibility that the patient will not have the required undivided attention that is necessary, because the aide will have several others to tend to as well, the aides time will be limited with each patient, especially if an emergency occurs within the facility. Due to other situations that occur within the nursing home, aides will not have the time to make sure each resident consumes their proper fluids and nutrients which are essential to daily intake. Malnutrition and dehydration are the main issues that affect the patients most of all, because of lack of the proper nourishment and fluids can lead to rapid skin breakdown and a quick decline in the health status. The patient will also be more prone to infections. Depression is an issue the family member will be faced with as well. Being stripped from everything you know is a heart wrenching experience of its own, which can lead to stress that will also affect their health. The wrong medicine given to the wrong resident is another issue. With all the patients that the nurse have to deal with on a daily basis, juggling them can result in such mistakes. Being understaffed can result in a many of mishaps. A majority of these mishaps can be avoided with the proper attention. The more you think about it, one on one attention is very important to ensure the safety and  well-being of your loved ones. HOME HEALTH CARE Another option when it comes to providing care for your loved one is home health care. This option allows the aide to assist your family member within their home. Home health care provides plenty of one on one attention, and allows the aide to focus entirely on the patient and the patient’s needs. This option can also be covered by Medicare, your private insurance company or out of pocket pay as well. The need for home health care is greater than ever. You will be able to choose the healthcare provider, which not only eases the mind of the guardian but it is also affordable, being that you are able to set a wage that is comfortable enough to meet the guardian’s or the relative needing assistance means of income. Who wouldn’t want their relatives to be cared for within the comforts of their own home? This specific kind of care will allow the guardian to feel more at ease. Even the LPN (licensed practical nurse), and RN (registered Nurse) make home visits as well. In this option, they are also assisted with activities of daily living. The one on one attention is the only attention your loved one will receive and is a repeated occurrence versus that of a nursing home. Vitals signs are also checked in this method of care. Another positive factor in this method is that there is a high possibility that the aide can develop a great relationship with the patient, which will allow the patient to feel more comfortable. The personal relationship can benefit the patient and the patient’s family greatly. This can also help the aide to pin point any improvements and odd changes in the patient’s health. Being that they are in a well-known environment, they are more likely to do for themselves more, rather than depending on the assistant they will be provided at a nursing home. Medical literatures has identified that a family member that is allowed to be cared for in the comfort of a familiar environment is less likely to become depressed. The one on one attention will guarantee the proper care for your loved one. Your family member will feel that sense of independence, which helps them emotionally as well as physically. CONCLUSION When it comes to ensuring the well-being of our loved ones, we have to weigh out the positive and negative in order to come up with the best choice possible. One on one attention that can truly assure the proper care that our loved ones need and deserve is definitely a positive factor. Just the idea of knowing that our loved ones are well taken care of is a gift within itself. At the end of the day, it is about family, their health, and how we can keep them in our lives longer.

The Autobiography of Malcolm X Free Essay Example, 1000 words

As such liberation can be achieved by remaining action less. There was another system of belief, the followers of which thought that ignorance is bliss. Their argument was, just like the nature of the child, who is simple, novice and without guile, the sins of an ignorant person deserve pardon as such he is blemish-less. At difference stages of his life, Malcolm made the best use of all the above philosophies, without clinging on to a particular one. Considering from the placement of destiny (fate), it subdued him at every turn of life, but Malcolm X, with his grit and determination, worked hard and intelligently to change its course. Bitter experiences of childhood made him a rebel. His father was cruelly murdered by the followers of Ku Klux Klan movement, his mother suffered mental breakdown, and his brothers and sisters were taken care of by the state welfare system.
