Advantages and Disadvantages Working in Large Corporation Essay Example for Free

Advantages and Disadvantages Working in Large Corporation Essay Nowadays, many students prefer to work in a large corporation compared to starting their own business. This is because if they want to create their own business, they required experience and a lot of bankroll to control their business. Although there are many students who prefer working in a large corporation, somehow there are still advantages and disadvantage working in such corporation. First of all, work in a large corporation will give us a great working experience. In fact, such experience is important for everyone no matter what job he or she is in today society. Sometimes, large corporation may decide to send employees that are less capable to their headquarters to gain more experience and train them. Therefore, experience is important as same as skill. In contrast, the office polity may fix you in a category or department that is not your specialty and you can’t transfer it because the department that you want to transfer is enough employees. As you are inexperienced in that the department, it makes you incompetent and inefficient working in the organization. An example could be someone who is working in finance is required to work in production engineering which will make them not able to use their skill from one job to another. Next, working in a large corporation will provides an employee and workers a stable salary notwithstanding the corporation is gain profit or loss at the end of month or year. That means employee can disburden about their income every month and make them feel that is the responsibility to finish their work on time. Besides that, the employee has a lot of opportunities to promote to high post if he or she works in a large corporation. Nevertheless, because this advantages, there are a lot of competitor to fight for the job. The workers and employees always need to work hard in order to do well in their work and to make sure they do not lose their jobs. Such hard work and long hours will create too much of stress which is unhealthy to the body. Last but not least, working in a large corporation has reduced the risk compare to the people who start their own business. For example, the owner of the company needs to solve a lot of problem such as how to reduce the ompany’s expenses when the company losing money, whereas as an employee, they do not need to be worry about the company losses. On the other hand, if work in a large corporation, it may conflict with other department for the benefit of each other. This will affect the relationship between the employees and also the company working system. Overall, working in a large corporation has advantage and disadvantage to us but I am favor of working in a large c orporation because the amount of training and development and security working such corporation.

Advantages and Disadvantages of Ethernet

Advantages and Disadvantages of Ethernet A 10Base2, or thin Ethernet, network uses thin 3/16-inch coaxial cable (with 50-ohm) impedance for the network backbone. Thin coaxial cable is much easier to prepare and install than thick Ethernet cable which means transfer rate of 10 Megabits per second that uses baseband signaling, with a contiguous cable segment length of 100 meters and a maximum of 2 segments. 10Base5: 10Base5 uses thick coaxial cable. This version is the original Ethernet. It can operate at up to 10 Mbps and support cable segments of up to 500 meters which uses baseband signaling, with 5 continuous segments not exceeding 100 meters per segment. It is also known as thick Ethernet or ThickNet. 10Base-T: 10BaseT is a baseband 802.3-based Ethernet network that uses unshielded twisted-pair (UTP) cable and a star topology. This version can operate at up to 10 Mbps which uses baseband signaling and twisted pair cabling. It is also known as twisted-pair Ethernet or UTP Ethernet. Features: 10BASE-T uses Manchester-encoding over two unshielded twisted-pair cables. The early implementations of 10BASE-T used Cat3 cabling. However, Cat5 or later cabling is typically used today. 10 Mbps Ethernet is considered to be classic Ethernet and uses a physical star topology. Ethernet 10BASE-T links could be up to 100 meters in length before requiring a hub or repeater. 10BASE-T uses two pairs of a four-pair cable and is terminated at each end with an 8-pin RJ-45 connector. The pair connected to pins 1 and 2 are used for transmitting and the pair connected to pins 3 and 6 are used for receiving. The figure shows the RJ45 pin out used with 10BASE-T Ethernet. 10BASE-T is generally not chosen for new LAN installations. However, there are still many 10BASE-T Ethernet networks in existence today. The replacement of hubs with switches in 10BASE-T networks has greatly increased the throughput available to these networks and has given Legacy Ethernet greater longevity. The 10BASE-T links connected to a switch can support either half-duplex or full-duplex operation. Advantages: Since each node on a 10 Base-T network has its own cable connecting it to a central hub, it is far less likely that any node can cause the entire network to fail. The hub also has a partitioning function built into it which allows it to detect a problem on any of its ports. If a problem is found, the node is disconnected from the rest of the network. This isolates the problem until the node can be troubleshot and repaired. Because of the partitioning function built in to the hubs and the star-wired topology, it is generally easy to troubleshoot a 10 Base-T network. In a worst-case scenario, one can be troubleshot by simply disconnecting nodes from the hub one at a time until the network recovers. Usually, the hub will give an indication as to which node is causing a problem, allowing the technician to troubleshoot that node as opposed to spending many hours finding where the problem is. Disadvantages: 10 Base-T only allows distances from the hub to the node of 100 meters. In some installations, this can be a major problem if nodes need to be located farther away. The nature of UTP cable makes it considerably more sensitive to electrical noise than coaxial cable. Generally, this rules 10 Base-T out as an option for installations on factory floor environments or other locations with a high ambient noise level. What are the different types of networking / internetworking devices? Explain the basic features of these devices. Following are the networking / internetworking devices with their basic features. Network Router: A network device, typically connected to a range of LAN and WAN interfaces, that forwards packets based on their destination IP address. Routers receives an incoming frame, discards the data-link header and trailer, makes a forwarding decision based on the destination IP address, adds a new data-link header and trailer based on the outgoing interface, and forwards the new frame out the outgoing interface. Network Repeater: A repeater is a physical layer device. It receives, amplifies (regenerates) and retransmits signals in both directions. As far as the software is concerned, a series of cable segments connected by repeaters is not different from a single cable (except by some delay introduced by repeaters). A system may contain multiple cable segments and multiple repeaters. But no two transceivers may be more than 2.5 km apart and no path between any two transceivers may be traverse more than four repeaters. Bridge: A bridge is a data link layer device which is used to connect multiple LANs. It examines the data link layer addresses to do routing. Since they are not supposed to examine the payload field of the frames they route, they can transport IPV4, IPV6, Apple Talk, ATM, OSI or any other kinds of packets. Gateway: A gateway can translate information between different network data formats or network architectures. Suppose a computer using the connection-oriented TCP/IP protocol needs to talk to a computer using the connection-oriented ATM transport protocol. The gateway can copy the packets from one connection to the other, reformatting them as need be. Switches: Switches are similar to bridges in that both route on frame addresses. In fact, many people use the terms interchangeably. The main difference is that a switch is most often used to connect individual computers. As a consequence, when a computer wants to send a frame to another the bridge gets the frame but just discards it. But the switch must actively forward the frame to other because there is no other way for the frame to get there. What is the range of addresses in the classes of internet addresses? Evaluate each class of logical addresses. There are five IP address classes, following table show each class and the range of addresses. Class Beginning Address Ending Address A 0.0.0.0 127.255.255.255 B 128.0.0.0 191.255.255.255 C 192.0.0.0 223.255.255.255 D 224.0.0.0 239.255.255.255 E 240.0.0.0 255.255.255.255 In Class A through Class E. each is used with a different type of network. The address classes reflect the size of the network, and whether the packet is unicast or multicast. In the unicast method of transmission, one copy of each packet is sent to each target destination. If there are eight workstations designated to receive a packet, such as a portion of a video clip, then it is transmitted eight times. In the multicast method, the recipients are placed in a group, such a group of all eight workstations. Only one packet is sent to the group, via a router or switch, which then packet to each group members. Class A is used for the largest networks composed of up to 16,777,216 nodes. Class A networks are identified by a value between 1 and 126 in the first position of the dotted decimal address. The network ID is the first 8 bits and the host ID is the last 24 bits. Class B is for medium-sized network composed of up to 65,536 nodes and it is identified by the first octet of bits ranging from decimal 128 to 191. The first two octets are the network ID, and the last two are the host ID. Class C addresses are used for network communication on small networks of 256 nodes or less. The first octet translates to a decimal value in the range of 192 to 223 and the network ID is contained in first 24 bits, while the host ID is contained in the last 8 bits. Class D addresses do not reflect the network size, only that the communication is a multicast. Unlike Classes A through C, the four octets are used to specify a group of nodes to receive the multicast, which consists of those nodes that are multicast subscription members. Class E is used for experimentation and address range from 240 to 239.255.255.255 in the first octet. Task 2 What is Bandwidth? Explain the other factors for network communications. Network bandwidth is the measure of the data carrying capacity of the network. When simultaneous communications are attempted across the network, the demand for network bandwidth can exceed its availability. The obvious fix for this situation is to increase the amount of available bandwidth. But, because of the previously stated constraints, this is not always possible. In most cases, when the volume of packets is greater than what can be transported across the network, devices queue the packets in memory until resources become available to transmit them. Queuing packets causes delay. If the number of packets to be queued continues to increase, the memory queues fill up and packets are dropped. The characteristics of the information being communicated also affect its management. For example, the delivery of a movie uses a relatively large amount of network resources when it is delivered continuously without interruption. Other types of service e-mail, for example are not nearly as demanding on the network. In one company, an administrator might decide to allocate the greatest share of the network resources to the movie, believing that this is the priority for his customers. This administrator may decide that the impact will be minimal if e-mail users have to wait a few additional seconds for their e-mail to arrive. In another company, the quality of a video stream is not as important as critical process control information that operates the manufacturing machinery. What is Physical address and what is the difference between Physical address and Logical address? Explain it in detail. The Physical address is specific on the local network and it represents the address of the end device on the physical media. In an Ethernet using LAN, this address is also called as Media Access Control address. On the local Ethernet network, when two end devices communicate, the frames that are exchanged between them contain the destination and source Media Access Control (MAC) addresses. It is in hexadecimal notation assigned by manufacturer. This address is much like postal address because it enables communication to be sent to specific destination. Physical address is 48-bit address burned into the ROM of the NIC card which is a Layer 1 device of the OSI model. This is divided into 24-bit vendor code and 24-bit serial address. This is unique for each system and cannot be changed. While the logical address is a 32- bit address assigned to each system in a network. This works in Layer3 of OSI Model which is generally called IP address. What is the difference between Layer 1, Layer 2 and Layer 3 devices? Describe it according to the Layers features. OSI model have 7 layers which perform many different functions. Every layer has its own unique features and function and a device which help the layers to work properly. Layer 1 is called Physical layer which consists of hardware, developed by engineers, in the form of electronic circuitry, media, and connectors. Therefore, it is appropriate that the standards governing this hardware are defined by the relevant electrical and communications engineering organizations. By comparison, the protocols and operations of the upper OSI layers are performed by software and are designed by software engineers and computer scientists. As we saw in a previous chapter, the services and protocols in the TCP/IP suite are defined by the Internet Engineering Task Force (IETF) in RFCs. Hardware components such as network adapters (NICs), interfaces and connectors, cable materials, and cable designs are all specified in standards associated with the Physical layer. Layer 2 is called Data Link layer and its services and specifications are defined by multiple standards based on a variety of technologies and media to which the protocols are applied. Some of these standards integrate both Layer 2 and Layer 1 services. A hub is an example of a layer 2 device. Switches are generally considered layer 2 devices, but many are capable of operating at layers 3, 4 or higher. Router is the Layer 3 device. The role of the router is to select paths for and direct packets toward their destination. This process is known as routing. During the routing through an internetwork, the packet may traverse many intermediary devices. Each route that a packet takes to reach the next device is called a hop. As the packet is forwarded, its contents (the Transport layer PDU), remain intact until the destination host is reached. Task 3 Explain 7 OSI layers briefly and define Router, Switch, and Bridge. Explain about encryption decryption. OSI Layers: The Open Systems Interconnection (OSI) model was initially designed by the International Organization for Standardization (ISO) that provides a framework on which to build a suite of open systems protocols. The objective was that this set of protocols would be used to develop an independent international network that would not be dependent on proprietary systems. Unfortunately, due to the rate at which it expanded, and the speed at which the TCP/IP based Internet was adopted, the OSI Protocol Suite development and acceptance lagged behind. Although few of the protocols, which are in widespread use today, are developed by using the OSI specifications, the major contribution has been made by the seven-layer OSI model in the development of other products and protocols for all types of new networks. The OSI model provides an extensive list of functions and services as a reference model that can occur at each layer. It also depicts the interaction of each layer with the directly above and below layers. No. Layer Name Description 7 Application Performs services for the applications used by the end users. 6 Presentation Perform data format information to the application. For example, the presentation layer tells the application layer whether there is encryption or whether it is s .jgp picture. 5 Session Manages sessions between users. For example, the session layer will synchronize multiple web sessions and voice and video data in web conferences. 4 Transport Defines data segments and numbers them at the source, transfers the data and reasonable the data at the destination. 3 Network Creates and addresses packets for end-to-end delivery through intermediary devices in other networks. 2 Data Link Creates and addresses frames for host-to-host delivery on the local LANs and between WAN devices. 1 Physical Transmits binary data over media between devices. Physical layer protocols define media specifications. Router: A network device, connected to a range of WAN and LAN interfaces that sends packets according to their destination IP address. Routers acquires an incoming frame, puts away the data-link header and trailer, makes a forwarding decision based on the destination IP address, adds a new data-link header and trailer based on the outgoing interface, and forwards the new frame out the outgoing interface. Switch: Switches are similar to bridges in that both route on frame addresses. In fact, many people use the terms interchangeably. The main dissimilarity is that a switch is commonly used to connect one-on-one computers. As a consequence, when a computer wants to send a frame to another the bridge gets the frame but just discards it. But the switch must actively forward the frame to other because there is no other way for the frame to get there. Bridge: A bridge is a data link layer device which is used to connect multiple LANs. It examines the data link layer addresses to do routing. Since they are not supposed to examine the payload field of the frames they route, they can transport IPV4, IPV6, Apple Talk, ATM, OSI or any other kinds of packets. Encryption: The process of obscuring information to make to unreadable without special knowledge, sometimes referred to as scrambling. The process takes the data to be encrypted and applies a mathematical formula to it along with a secret number (called an encryption key). The resulting value, which is called an encryption packet, is sent through a network. Decryption: It is the process of decoding data the back to its original form by giving that encryption key.

Evaluation of Mary Shelleys Frankenstein Essay -- Mary Shelley Franke

Evaluation of Mary Shelley's Frankenstein Form, Structure and Plot   Ã‚  Ã‚  Ã‚  Ã‚  Frankenstein, an epistolary novel by Mary Shelley, deals with epistemology, is divided into three volumes, each taking place at a distinct time. Volume I highlights the correspondence in letters between Robert Walton, an Arctic seafarer, and his sister, Margaret Saville. Walton's letters to Margaret basically explain his expedition at sea and introduce Victor Frankenstein, the protagonist of the novel. Volume II is essentially Frankenstein's narrative, told in his point of view, with much action, death, and many more characters. There are a few chapters within this volume in which the monster narrates his adventures while alone. Volume III displays Victor's death and the monsters portrayal as a desperate character. Robert Walton also writes one final letter to his sister, explaining the remainder of Victor's story. The story is written chronologically, but because Victor's narrative brings about a flashback, it seems as if Victor is found, then the story shifts ba ck in time to Victor?s youth and works its way back into present time. Volume I and Volume III are written in Walton?s perspective but Volume II is written mostly in Frankenstein's point of view. The work follows the patterns of an epistolary novel in that letters introduce the plot, the plot itself follows, and then letters to commence the plot end the story. The actual happenings of Frankenstein cover a two year period, but this does not include Victor?s narrative in Volume II. Characters   Ã‚  Ã‚  Ã‚  Ã‚  The characters that serve as narrators at some time during the story, Robert Walton Victor Frankenstein, and the daemon, may be considered believable. Walton describes his aspirations and limited findings, which lack room for inaccuracies. Frankenstein?s narrative, which seems somewhat farfetched at first with the introduction of the monster, proves itself as believable due to the raw emotions he expresses. The monster?s narrative is also believable because it just accounts for what he had done to fill time while alone in the woods.   Ã‚  Ã‚  Ã‚  Ã‚  Victor Frankenstein, one of the novel?s round characters, may be described as a creative, knowledgeable, and reserved man in his middle ages. The novel is unique in that Victor Frankenstein is both the protagonist and antagonist, consequentially creating a conflict of man versus himself. W... ...n my native   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  wood, nor known nor felt beyond the sensations of hunger, thirst, and   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  heat! Of what a strange nature is knowledge! (119).   Ã‚  Ã‚  Ã‚  Ã‚  The theme only heightens toward the end when Frankenstein sputters his dying words: ?Farewell, Walton! Seek happiness in tranquility and avoid ambition, even if it be the only apparently innocent one of distinguishing yourself in the science and discoveries. Yet why do I say this? I have myself been blasted in these hopes, yet another may succeed.? (215). It is only appropriate that his dying words confront the main them of the story. In essence, Frankenstein is confirming that knowledge is, in fact, dangerous, but even more dangerous is not pursuing knowledge for if one were to succeed, he would open that field up to all of mankind. Significance of Title There seems to be no true significance of the title Frankenstein. It seems merely to be named after the story?s main character, protagonist, antagonist, and, of course, its roundest character. Works Cited: Shelley, Mary Wollstonecraft.

The Oppression of Women Drives The AIDS Epidemic in Africa :: Disease AIDS Essays Africa Women

The Oppression of Women Drives The AIDS Epidemic in Africa Africa is facing a devastating crisis with respect to the AIDS epidemic, currently accounting for over 70% of the world's HIV-positive population. There are, of course, many factors that drive the explosive transmission of the Human Immunodeficiency Virus, but in the tangled web that is the epidemic in Africa, many of these issues share a common thread. The oppression of women in Africa can be considered the virus' cultural vector. Females are rendered powerless in African societies, and existing gender inequalities are largely responsible for the spread of the disease. Females' disadvantaged position in society is intrinsically linked to the subordination of women in their relationships with men. In order for progress to be made, an examination of gender relations and empowerment for women must take place. To be successful, AIDS campaigns must be built on the existing organizational skills of women, but must incorporate men as well. The blatantly skewed distribution of power in Afri can patriarchal societies makes women extremely vulnerable but has dangerous implications for all. To examine the forces that steer the epidemic down its course, the epidemiology of HIV and AIDS in Africa must first be considered. More than 80% of all HIV infections in Africa are acquired through heterosexual contact. This statistic is grossly out of balance with the 13% rate of infection through heterosexual contact in the United States. Vertical transmission from mother to child is the second most common route for the virus to take in Africa (Essex et al., 158). These rates are generally much higher than in the United States and Europe, where the use of a drug called neviropine has drastically reduced mother-to-child transmission. This disparity is a direct result of differences in the nations' wealth. African nations simply cannot afford to provide the drug to infected pregnant women. The continued transmission of HIV through contaminated blood during processes such as blood transfusions is another dismal consequence of poverty and inferior health services in many African count ries. This method accounts for the third most important mode of transmission, one that has been virtually eradicated in many countries because the technology is available to prevent it (Essex et al., 159). Part of what makes the situation in Africa so devastating is that the primary roads the virus travels in Africa were shut down long ago in other countries. Much of the world's population already takes many of the roadblocks for granted.

Graduation Speech: We Can Be Heroes -- Graduation Speech, Commencemen

Class of 2012, as we sit here this evening, I would like you to take a look at the classmates sitting around you. Many students have given countless hours of time, energy, and passion to worthy cuases that they have been a part of throughout high school. However, those aren't the only students deserving of recognition this evening. We have students here tonight, who have taken a stand for what they believe in, not even hesitating to compromise their reputations. I believe there are many ordinary heroes wearing caps and gowns tonight. Many of you are heroes because you challenge yourselves to be more accepting of those around you. Some of you heroes woke up every day and came to school with the desire to reach out to those hurting and in need of a friend. Other heroes went the extra mile to make someone feel important, encouraging them and offering hope they may not otherwise have experienced. One of our deepest needs as humans is to be valued. The need to be needed is often more powerful than the need to survive. Every one of us has a deep longing to write our signature on the world. As individuals, we are each equipped with unique gifts and talents to share with our family, our community, and our world. Nelson Mandela once said, "As we let our own light shine, we unconsciously give other people permission to do the same. As we are liberated from our own fear, our presence automatically liberates others." When we open ourselves to become all that we were created to be, we allow those around us to be themselves, empowering them to be a unique individual and to use the talents they possess. It doesn't matter if we are brilliant, beautiful, or incredibly charismatic. We can make a difference by just being who we are. We simpl... ...ctivities, while encouraging us to be our best. These acts of love and many more are what make you our heroes. Class of 2012, I challenge you to recognize the heroes in your life, and continue to be heroes yourselves. Author Charles Swindoll said, "We need heroes. I mean genuine heroes, authentic men and women who are admired for their achievements, noble qualities, and courage. Such people aren't afraid to be different. They risk. They stand a cut above." Swindoll's message speaks so highly of those who are heroes and those who have the potential to be heroes. So, here is my challenge to you. Rise above your fears, take risks, and don't let your abilities collect dust. Instead, live life passionately, dream big, and seek every day in ways small and large to write your signature on the planet. But be careful ... you may just empower someone else to do the same.

It’s Better To Live In A Small Town Than A Big City

Nowaday, People often have 2 selection for their living place. Some people prefer to live in small town and Others prefer to live in the big city. I think one of the most important decisions that human have to take is to choose his living place where you can feel more comfortable,more suitable and happier. Peronally, I think setting down in modern big city is more beneficial. Through my essay I will analyze one of the most important reasons which is Chance of having a better carreer.Big cities has bigger market, companies or corporations are more famous so of course you can have more chance to found a better work . I have a same age friend. He study IT in an university in Thai Nguyen city , It’s a city which smaller than Ha Noi capital. He graduated from a famous university but after 1 year in Thai Nguyen he still unemployed Because number of companies fewer means you will have less chance. There are too many student graduated from university each year but number of companies is only slightly increased.Many student together apply in to one company. Having too much CV of employees but employment in the company are limited so maybe you must to win hundred of people,who applied together with you in order to have employment in the company and my close friend can’t do that. After that I advice him to go to Ha Noi to find another chance and he agreed. He went to Ha Noi and applied to some companies. Amazing! Having 3 companies want to contract with him after only 2 months.He contracted with FPT corporation and work as a Software Specialist about computer. Now he still work there and feeling very happy when being a FPT's staff. From this example we can see that there are more activities in big cities that help people to expose their chance. It is clear from the example that we can have better opportunities in big cities. In a nutshell, I am still positive living in big city is Hanoi where will allow me have better work chance. And I believe that many peo ple will move to here for the same reason. It’s better to live in a small town than a big city Nowaday, People often have 2 selection for their living place.
