Impact Of Current Small Networks

Impact Of Current Small Networks One of the ways to categorize the different types of computer network designs is by using their scope or scale in account. Almost every type of design as some kind of area network is referred by networking industry and that is due to history of computer networking. Common examples of area network types are:- A LAN is used to connect network devices over short distance like an office building, school, or home. Generally a single LAN is used, though sometimes one building will contain a few small LAN, and occasionally a LAN will cover a group of nearby buildings. Moreover LANs are also typically owned, controlled, and managed by a single person or organization. WAN Wide Area Network A WAN covers a large distance. The Internet is the largest WAN, spanning the Earth. A geographically-dispersed collection of LANs is a WAN. Routers are used to connect LANs to a WAN. Most WANs (like the Internet) are not owned by any one organization they are under distributed ownership and management. LAN, WAN and Home Networking Home users use LAN and connect to the Internet WAN through an Internet Service Provider (ISP) using a broadband modem. Once connected, all computers on the home LAN can communicate directly with each other and they are bound to go through a central gateway, typically a broadband router, to reach the ISP. Some other types of networks are also classified:- Wireless Local Area Network a LAN which is based on WiFi wireless network technology Metropolitan Area Network owned and operated by a single entity such as a government body, it is a network covering a physical area larger than a LAN but smaller than a WAN, such as a city. Campus Area Network a network covering multiple LANs but smaller than a MAN, such as on a university or local business campus. System Area Network it is used to link high-performance computers with high-speed connections in a grouped configuration. It is also called as Cluster Area Network. Range of some devices on the network:- Laptop: When using a laptop with public hotspots, a strong Wi-Fi signal is must for successful Internet access and good connection speed. A wireless laptop with limited range will most probably suffer from slow Internet connections. Smart phones, PDAs, etc.: It is perfect to free the most portable of all devices to be freed from wires. For that we need a fast Internet connection (DSL, cable model or wired Ethernet) with a Wi-Fi access point start.   Other than this we use some devices such as Digital Media Server (DMS), Digital Media Controller (DMC), Digital Media Printer (DMPr) etc, for devices on network. Task 2- briefly describe each device participation/role in the network. Example; Router to connect to the Internet, etc. Computer network devices also called communication devices and they have a data communication network. We have routers, switches, hubs, LAN cards, gateway, modems, hardware firewall, CSU/DSU, ISDN terminals and transceivers under this head. These devices are must need for data communication in an Ethernet or WAN network. Understanding of these devices is necessary for an IT professional or a network administrator. After selection of best devices one must ensure that they are compatible with each other. The top vendors are Cisco, D-Link, LinkSys, Baynet, RealTek, 3Com, NetGear, Intel, Nortel, and Lucent etc. These vendors help you get devices. We can reduce the operational cost and enhance the overall performance dramatically by a well designed IT infrastructure with the proper placement of the routers, servers, gateway and switches. Routers:- It is a communication device which is used to connect two logically and physically different networks, two LANs, two WANs and a LAN with WAN. Router is mainly used to sort and the distribute data packets to their destinations according to their IP addresses. Router is a main device for the connectivity between the enterprise businesses, ISPs and in the internet infrastructure. Cisco routers are widely used in the world. Every router has IOS which is routing software. Router does not broadcast the data packets. Switches:- Alike the router, a switch is an intelligent device which is used to map the IP address with the MAC address of the LAN card. It sends the data packets only to the destined computer. Switches are used in the LAN, MAN and WAN. There are three methods to transmit the data in a network via switches i.e. store and forward, cut through and fragment free. Hubs Hub is a central connecting device in a computer network. There are two types of a hub i.e. active hub and passive hub. Every computer is directly connected with the hub. Data packets are broadcasted to all the LAN cards in a network and the destined recipient picks them and all other computers discard the data packets. Hub has five, eight, sixteen and more ports and one port is known as uplink port, which is used to connect with the next hub. Modems It is a communication device that is used to provide the connectivity with the internet. Its working is in two ways: modulation and demodulation. Either it coverts the digital data into the analog or analog to digital LAN Cards LAN cards are the building blocks of a computer network. They are also called as network adapters. A properly installed and configured LAN card is need for computers to communicate. A unique IP address every is there with every LAN card. Different LAN cards support different speeds. Multiplexer It is used to combine the several electrical signals into one signal. Task 3 briefly describe and evaluate the impact of SOHO networks, such as; †¢ limited connections †¢ number of devices on the network †¢ usage social networking, video-streaming, entertainment, gaming, home working, etc. †¢ security Firewalls, sharing folders, VPN, wireless encryption, etc. †¢ Bandwidth constraints †¢ User expectations †¢ Sharing of resources †¢ Use of technology †¢ Communications Bluetooth, 3G, Broadband, etc. The small office home office has gone through a great transformation in recent years as technology has advanced to another level. Small office/home office (SOHO) network is growing in popularity among network types. It is a modern concept for the category of business, which involves from 1 to 10 workers.. To a great extent companies which market products targeting the great numbers of small businesses that have a small or medium sized office use SOHO. Basically it includes less than 10 PCs and may not include servers at all. Network resources such as DNS server resolution and e-mail servers are generally located offsite, either hosted by an ISP or at a corporate office. Cable, DSL, or perhaps ISDN are used to provide internet access for the SOHO network. An inexpensive router is used for the boundary between the LAN and the WAN connections. This router may also serve double duty as a firewall to shield the SOHO network from malicious activity. To provide interconnections between clie nt PCs and the router, and many routers include an integral hub or switch. It has simplicity that is why Ethernet is generally the LAN standard used to wire the SOHO network. Wireless standards such as 802.11b are starting to appear for a vital use in the SOHO market. It eliminates the need for adding LAN wiring in the home. When a small office needs to connect to a corporate environment with security involved then some sort of VPN device is either built into the router itself or on the LAN. We must ensure security for SOHO networks. As there is increase in number of employees so are their sophisticated computer networks in their homes. It comprise a mix of personal and company equipment. Many enterprises believe that practice of conducting work at home on employee-purchased PCs or networking equipment will save them money. However, we are bound to face security problems when users link personal systems to the corporate network. This is most in the cases when enterprises fall prey to false assumptions about the associated risks. While working from home on network-connected personal systems, enterprise data can be dangerously exposed by employees. For security: before turned in for service, users must be warned about the exposure risks of leaving personal and business data on personal systems. PCs with preloaded safeguards such as disk encryption can be a solution too. At least, encouragement should be there for employees to use system passwords and disk encryption. A combination of policy control, configuration lockdown, personal firewall, and central firewall filters to block installation of the better-known file-sharing and remote-control programs can be used. Similarly protection methodology can be used for personal systems. Enterprises shouldnt rely on employees personal equipment and networks conform to enterprise security and privacy standards. They should follow best practices to ensure security. Training and awareness programs will help remind users of the risks of data exposure and the potential damage such exposure can cause to themselves and the enterprise. They can implement thin client computing solutions, which minimize the risk of data exposure on non enterprise-owned systems.

Charlotte Temple - Ideas of Love Essay -- essays papers

Charlotte Temple - Ideas of Love In the 18th century, when Charlotte Temple was written, society’s ideas about women, love, and obligations were extremely different from views held in the 20th century. Women did not have many rights, and society made them think that their place in life was to marry well. They were not supposed to have desires or hopes for an amazing kind of love. They were merely supposed to marry the man who their families intended them to marry, and live their lives being a dutiful wife and mother. Love had a similar essence in the 1700’s. It was not looked at as being essential to a relationship; convenience and social status was more important than love in an 18th century marriage. Finally, social obligations were almost completely opposite then to what they are now. As opposed to 20th century obligations to the self, education, and wealth, the 18th century focused more on social status and family, and not so many personal or independent obligations. (â€Å"Eighteenth†) In Charlotte Temple, a radical idea concerning a breakdown of social norms, and a restructuring of important obligations was presented. Familial and social responsibilities seemed to take a backseat to Charlotte’s (and other characters) independent and personal lives. For this reason, Charlotte Temple was a revolutionary novel that gave people in the 18th century a new way of looking at life. It emphasized love and emotions, while disregarding normal cultural ideas. In the beginning of the novel, familial or social obligations were told through the stories of Mr. Temple, Charlotte, and La Rue. The narrator remarked that Mr. Temple’s brother was â€Å"made completely wretched by marrying a disagreeable woman, wh... ...iserable and alone. The two women began Charlotte Temple in the same fashion: looking for independence and self-worth. However, then endings of the two women were different. It seemed as if the narrator is saying if one never leaves or even returns to social obligations, the end result will be happiness. If one denies obligations, then the end result will be misery. This novel, however radical it was regarding the risks of social and familial obligations for personal attribution, basically stated at the end that the one who does adheres to obligations will be happy in the end. So, in conclusion, Charlotte Temple did break down social norms by presenting the idea that people could have resisted â€Å"normal† social obligations to pursue personal happiness. However, it was not so radical as to say that one would have been happy if they denied their duties.

Theme of Social Class in Great Expectations

One theme from Charles Dickens’ Great Expectations is the great difference in social classes. Throughout the story the main character, Pip, goes from living in a small, poor village, destined to be a blacksmith to becoming a wealthy gentleman who lives in a large home in London. During Pip’s journey a clear divide can be seen between the wealthy, high class of England and the poor laborer class.This divide between classes is seen as soon as the first higher class person in the story is mentioned: Miss Havisham. When Mrs. Joe and Mr. Pumblechook discuss Pip visiting Miss Havisham’s house to play, Pip recalls, â€Å"I had heard of Miss Havisham up town – everybody for miles round, had heard of Miss Havisham up town- as an immensely rich and grim lady who lived in a large and dismal house barricaded against robbers, and who led a life of seclusion† (Dickens 50).Even though Miss Hivisham spends all her time in seclusion up town she is known for miles ar ound because of her high standings, which gives a sense that the high class led extremely different existences than the poor. This theme is seen again when Pip tries to teach Joe things he has learned from Miss Havisham: â€Å"What I acquired, I tried to impart to Joe. This statement sounds so well, that I cannot in my conscience let it pass unexplained.I wanted to make Joe less ignorant and common, that he might be worthier of my society and less open to Estella's reproach† (Dickens 109). Even with the small amount Pip has learned about being a gentleman he already feels like he is on a different level than Joe and that Joe would have something to gain from being more like him. The sharp division of classes appears many other times during Great Expectations and helps show how different life was for different groups of people in England. The book gives two distinct viewpoints for this time period.

On April 14, 2017, I was reminded to never take life for granted. When you’re seventeen, you think you have all the time in the world. However, on this day, time came rushing in. I had just put on my bathing suit and gone to the beach barely even making a dent in the sand. My cell phone buzzed continuously like the nagging of a dog whining for food at the foot of the dinner table. The type of noise you drown out constantly. After settling into a soft sandy spot, I decided to take a quick peep at the missed calls. My sister had called multiple times which is rare. A little curious, I called her back. She answered in a panic with the muttering of alarming words â€Å"Mom’s been run over, and we have to go home now!

Every visitor including family, friends, and hospital employees believed it was a miracle that the outcome wasn’t worse. They said she was the miracle on the fourth floor. Luckily, our neighbor is the surgeon at our local hospital. After she heard about the incident, she was the first to respond as she was on trauma duty that afternoon. This was yet another great example of an angel looking out for us! The problem was finally solved. My mom had to have her gall bladder removed. After long, and painful months in and out of doctors’ offices, my mom was so relieved that a solution was found. Dr. Kimberly, the surgeon, said her gall bladder was the worst case she had ever seen. The surgery was to be held at ten o’clock the following morning. It was time for my sister and me to leave the hospital and head home. A night in the house without our mom wasn’t going to be pleasant. Every night, sh e always shouts â€Å"Goodnight girls, I love ya’ll.† My sister and I stayed home alone that night in what seemed like the quietest house we’ve ever been in.
