What makes a good website?   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Introduction In my opinion what makes a good web page? I have been on the net for the last, can’t really believe it, coming to ten years now. From the conception to now, I have been a regular surfer on the web, visiting thousands of pages a month, mostly in search of some thing or another. Most searches have lead to even more searches but some times I come up tops. Having been used to the all text sites of the beginning, and seeing the first implementations of more graphic based sites, there was a three-year lapse where I rarely got to surfing and missed a whole evolution in web page. When I returned in full to surfing, I discovered the face of the internet have started to change. Buttons with pictures, navigation systems, some that even worked, all and all better thought out sites that where pleasing to look at and better to work with. This was probably due to the introduction of java script and more complex versions of html. Before then what made a sight good or bad, for me, was more bas ed on contents. As this change came to be my expectations of sites changed as well. When, at first, we where happy to have hyperlinked, underlined blue text, now we expect to have a good, easy to use, constant navigation system. Where bad resolution bitmaps where the norm, now we want smooth animated graphics. The way we use the internet have changed with the advances in technology, so changing our expectations and creating a whole new set of problems for anyone, from the big spenders to backroom designers, how to get our attention and how to keep us coming back. First impressions: The first thing that I look for in a web site is definitely something to draw my attention. I am not picky, but it normally comes in the style of some sort of graphic. Will it be the company logo, background image, or even just the colour used in the background, any of them can make me take a second look and so giving the designer a chance to get me into the rest of the site. The newer sites these days come with splash pages, advertising to you what you can expect on the inside, but like all advertising can become its own undoing by either chasing you away in the first place or misrepresenting what you are going to find there.

Advantages and Disadvantages of Normal Lan vs. Wireless Lan

Advantages and disadvantages of normal LAN vs. wireless LAN. Computer networks for the home and small business can be built using either wired or wireless technology. Wired Ethernet has been the traditional choice in homes, but Wi-Fi wireless technologies are gaining ground fast. Both wired and wireless can claim advantages over the other; both represent viable options for home and other local area networks (LANs). Below we compare wired and wireless networking in five key areas: †¢ease of installation †¢total cost †¢reliability †¢performance †¢security About Wired LANs Wired LANs use Ethernet cables and network adapters. Although two computers can be directly wired to each other using an Ethernet crossover cable, wired LANs generally also require central devices like hubs, switches, or routers to accommodate more computers. For dial-up connections to the Internet, the computer hosting the modem must run Internet Connection Sharing or similar software to share the connection with all other computers on the LAN. Broadband routers allow easier sharing of cable modem or DSL Internet connections, plus they often include built-in firewall support. Installation Ethernet cables must be run from each computer to another computer or to the central device. It can be time-consuming and difficult to run cables under the floor or through walls, especially when computers sit in different rooms. Some newer homes are pre-wired with CAT5 cable, greatly simplifying the cabling process and minimizing unsightly cable runs. The correct cabling configuration for a wired LAN varies depending on the mix of devices, the type of Internet connection, and whether internal or external modems are used. However, none of these options pose any more difficulty than, for example, wiring a home theater system. After hardware installation, the remaining steps in configuring either wired or wireless LANs do not differ much. Both rely on standard Internet Protocol and network operating system configuration options. Laptops and other portable devices often enjoy greater mobility in wireless home network installations (at least for as long as their batteries allow). Cost Ethernet cables, hubs and switches are very inexpensive. Some connection sharing software packages, like ICS, are free; some cost a nominal fee. Broadband routers cost more, but these are optional components of a wired LAN, and their higher cost is offset by the benefit of easier installation and built-in security features. Reliability Ethernet cables, hubs and switches are extremely reliable, mainly because manufacturers have been continually improving Ethernet technology over several decades. Loose cables likely remain the single most common and annoying source of failure in a wired network. When installing a wired LAN or moving any of the components later, be sure to carefully check the cable connections. Broadband routers have also suffered from some reliability problems in the past. Unlike other Ethernet gear, these products are relatively new, multi-function devices. Broadband routers have matured over the past several years and their reliability has improved greatly. Performance Wired LANs offer superior performance. Traditional Ethernet connections offer only 10Mbps bandwidth, but 100 Mbps Fast Ethernet technology costs little more and is readily available. Although 100 Mbps represents a theoretical maximum performance never really achieved in practice, Fast Ethernet should be sufficient for home file sharing, gaming, and high-speed Internet access for many years into the future. Wired LANs utilizing hubs can suffer performance slowdown if computers heavily utilize the network simultaneously. Use Ethernet switches instead of hubs to avoid this problem; a switch costs little more than a hub. Security For any wired LAN connected to the Internet, firewalls are the primary security consideration. Wired Ethernet hubs and switches do not support firewalls. However, firewall software products like ZoneAlarm can be installed on the computers themselves. Broadband routers offer equivalent firewall capability built into the device, configurable through its own software. About Wireless LANs Popular WLAN technologies all follow one of the three main Wi-Fi communication standards. The benefits of wireless networking depend on the standard employed: †¢802. 11b was the first standard to be widely used in WLANs. †¢The 802. 11a standard is faster but more expensive than 802. 11b; 802. 11a is more commonly found in business networks. †¢The newest standard, 802. 11g, attempts to combine the best of both 802. 1a and 802. 11b, though it too is more a more expensive home networking option. Installation Wi-Fi networks can be configured in two different ways: †¢Ã¢â‚¬ Ad hoc† mode allows wireless devices to communicate in peer-to-peer mode with each other. †¢Ã¢â‚¬ Infrastructure† mode allows wireless devices to comm unicate with a central node that in turn can communicate with wired nodes on that LAN. Most LANs require infrastructure mode to access the Internet, a local printer, or other wired services, whereas ad hoc mode supports only basic file sharing between wireless devices. Both Wi-Fi modes require wireless network adapters, sometimes called WLAN cards. Infrastructure mode WLANs additionally require a central device called the access point. The access point must be installed in a central location where wireless radio signals can reach it with minimal interference. Although Wi-Fi signals typically reach 100 feet (30 m) or more, obstructions like walls can greatly reduce their range. Cost Wireless gear costs somewhat more than the equivalent wired Ethernet products. At full retail prices, wireless adapters and access points may cost three or four times as much as Ethernet cable adapters and hubs/switches, respectively. 802. 1b products have dropped in price considerably with the release of 802. 11g, and obviously, bargain sales can be found if shoppers are persistent. Reliability Wireless LANs suffer a few more reliability problems than wired LANs, though perhaps not enough to be a significant concern. 802. 11b and 802. 11g wireless signals are subject to interference from other home applicances including microwave ovens, cordless tel ephones, and garage door openers. With careful installation, the likelihood of interference can be minimized. Wireless networking products, particularly those that implement 802. 11g, are comparatively new. As with any new technology, expect it will take time for these products to mature. Performance Wireless LANs using 802. 11b support a maximum theoretical bandwidth of 11 Mbps, roughly the same as that of old, traditional Ethernet. 802. 11a and 802. 11g WLANs support 54 Mbps, that is approximately one-half the bandwidth of Fast Ethernet. Furthermore, Wi-Fi performance is distance sensitive, meaning that maximum performance will degrade on computers farther away from the access point or other communication endpoint. As more wireless devices utilize the WLAN more heavily, performance degrades even further. Overall, the performance of 802. 11a and 802. 11g is sufficient for home Internet connection sharing and file sharing, but generally not sufficient for home LAN gaming. The greater mobility of wireless LANs helps offset the performance disadvantage. Mobile computers do not need to be tied to an Ethernet cable and can roam freely within the WLAN range. However, many home computers are larger desktop models, and even mobile computers must sometimes be tied to an electrical cord and outlet for power. This undermines the mobility advantage of WLANs in many homes. Security In theory, wireless LANs are less secure than wired LANs, because wireless communication signals travel through the air and can easily be intercepted. To prove their point, some engineers have promoted the practice of wardriving, that involves traveling through a residential area with Wi-Fi equipment scanning the airwaves for unprotected WLANs. On balance, though, the weaknesses of wireless security are more theoretical than practical. WLANs protect their data through the Wired Equivalent Privacy (WEP) encryption standard, that makes wireless communications reasonably as safe as wired ones in homes. No computer network is completely secure and homeowners should research this topic to ensure they are aware of and comfortable with the risks. Important security considerations for homeowners tend to not be related to whether the network is wired or wireless but rather ensuring: †¢the home's Internet firewall is properly configured †¢the family is familiar with the danger of Internet â€Å"spoof emails† and how to recognize them †¢the family is familiar with the concept of â€Å"spyware† and how to avoid it †¢babysitters, housekeepers and other visitors do not have unwanted access to the network Conclusion You've studied the analysis and are ready to make your decision. Bottom line, then, which is better – wired or wireless? The table below summarizes the main criteria we've considered in this article. If you are very cost-conscious, need maximum performance of your home system, and don't care much about mobility, then a wired Ethernet LAN is probably right for you. If on the other hand, cost is less of an issue, you like being an early adopter of leading-edge technologies, and you are really concerned about the task of wiring your home or small business with Ethernet cable, then you should certainly consider a wireless LAN.

Computers Are Making Users Sick †Health and Safety Essay

Computers Are Making Users Sick – Health and Safety Essay Free Online Research Papers Computers Are Making Users Sick Health and Safety Essay Almost half of all PC users in the UK have experienced health problems caused by using computers, research has found. According to a poll conducted by computer retailer PC World, eye strain was the most common problem associated with computer use, suffered by 25 per cent of users. About 15 per cent had experienced back pain, while headaches were experienced by 14 per cent of users. Of those surveyed, 11 per cent cited wrist pain and 10 per cent shoulder pain caused by prolonged PC use. A PC World representative said that health and safety guidelines introduced in UK businesses had not trickled down to home users. â€Å"It’s too easy to compromise your health. Adopting a simple routine of looking up, easing up or stretching and ultimately getting away from the PC can help you to avoid some of the aches and pains caused by extended use,† he said. In an average day, 18 per cent of people spend two or more hours using a PC at home, and 15 per cent at work. Two in five respondents took no breaks in two hours of PC usage. Respondents were also asked whether they used any of a range of products including flat-screen monitors, which help minimise eye strain, and ergonomic keyboards and mousemats. The majority of home users, 59 per cent used none of these products, with 54 per cent at work also using none. The most popular product was the mousemat with wrist rest, with 27 per cent of home PC users and 31 per cent at work using these products. Monitor screens designed to minimise glare were used by 14 per cent at home while six per cent were using ergonomic keyboards. In conjunction with the charity AbilityNet, PC World said it would launch a campaign to raise awareness of good computing practice to minimise the health risks associated with PC use.AbilityNet hopes to raise awareness of the health risks of PC use.

Information on Arizona Education and Schools

Information on Arizona Education and Schools When it comes to education and schools, each state takes its own unique approach. For the most part, state governments and local school boards develop educational policy and mandates that shape education and schools within state and local boundaries. Though there is some Federal oversight, most highly debated education regulations are shaped more closely to home. Trending educational topics such as charter schools, standardized testing, school vouchers, teacher evaluations, and state adopted standards typically align with the controlling political parties philosophy. These differences have made it difficult to compare education and schools between states accurately.   They also ensure that a student living in a particular state will be receiving at least a somewhat different education that a like student in a surrounding state. There are many data points that can be used to compare education and schools among states.

Arguing to Persuade Essay Example | Topics and Well Written Essays - 1000 words

Arguing to Persuade - Essay Example Argument to persuasion invites more use of language resources than argument to persuade (Caine 54). A persuasive paper intends to use logic and reasoning to convince others abandon their stands and beliefs and be conformed to the writers views). In this regard, this writing prior to preparation is necessary. There are stipulated steps that, if followed would result to a high performing persuasive paper. To begin with, an author should choose a certain stand (Wachob 34). Before one embarks on convincing others about his point of view, he or she must be sure of what he or she believes. Understanding and analyzing the audience follows; after this, the writer must delve into serious research on the topic. This enables one form concrete decisions, explanations to every statement and also boosts personal confidence and esteem. It is also in this level that one understands the failures of former works in the topic and develops mechanisms to counter them. The research on the topic also helps indentify reliable and legitimate sources of information and experts on the same. From the research plane, one is to develop a hypothesis, a proposition, a claim on the topic. The hypothesis should be debatable, carry with it two opposing ends. One can resort to having a thesis that stands against his or her stand, doing this ensures that the claim is debatable. The next move is to try and extrapolate possible refutations against your stand. This stage can be meant to do two things, prepare one psychologically to defend his or her stand and prepare answers to the refutations citing legitimate and available evidences (Forsyth 23). The next point is to provide concrete reasons for a particulate stand. This can be done by providing evidences by the use of facts, statistics from dependable sources and by the use of illustrations and examples. There are elements of a good persuasive writing. There should be order of how things get presented. This allows a clear flow of information witho ut conflicting of ideas, facts and truths. To start with is the introduction of the paper. This part gives an oversight of the paper and should not to be too lengthy. Terminologies in the topic of the paper should be defined and be explained at this point. Explanation of the background of the paper can also be given in the introduction (Caine 64). In the end of introduction, the claim should be introduced in a clear and precise way. The thesis can tell the reader the actual topic of the paper and the organization of the paper After introduction and having stated the thesis, the next thing in line is defending the thesis by providing evidences. This happens in the body of the paper and should take a minimum of three paragraphs. The thesis carries the whole paper. At this point, it is healthy to have the extrapolated refutations in the fingertips so as to start countering them from the very first defense. The paragraphs should also be arranged in accordance with the weight of the evid ences, starting from the beast to the least. The last statement of the paragraph should also be able to link with the next paragraph in a manner that embraces a perfect flow of information. (Wachob 39) After a perfect statement of the writers evidences, the paper should proceed to a new paragraph or segment that purely focuses on refutations. Since the writer communicates through writing, he or she is denied the chance of getting

Ethics and Professional Code of Conduct Essay Example | Topics and Well Written Essays - 500 words

Ethics and Professional Code of Conduct - Essay Example Integrity ensures that such persons respect the citizens’ constitutional rights, liberty and adhere to the values of justice and fairness in their duties to the citizens (Gaines & Kappeler, 2011, p 345). In this case, the professional is capable of ensuring fairness in his or her duties and refraining from unjust use of authority. Secondly, ethics and integrity ensures that police chief exercises reasonable courtesy while interacting with the public. In this case, the police chief or county sheriff is able to refrain from mocking, embarrassing, ridiculing or humiliating subordinates or fellow officers in order to incite them to violence. Thirdly, ethics and integrity will enable such professionals to observe confidentiality of information that is available to them in their capacity as senior law enforcement officers (Gaines & Kappeler , p 343). The officers should not willfully violate any legal restrictions that restrict the dissemination of the private information and should not disclose information that may endanger the life of a complaint or victim to a crime. There is a clear difference between ethics, morality and law as pertains to the duties of law enforcement officers. Ethics are external standards that are set by the law enforcement profession and are regarded as the social system or framework that should offer the acceptable behavior in the execution of duties of the law enforcement officer (Hess & Orthmann, 2011, p189). Morality refers to the law enforcement officer’s own principles regarding what is right or wrong. Morality is internal as it reflects the habits, beliefs, culture, and religion of an individual while ethics are external since they are set by the profession. Morality is guided by the existing cultural norms while the ethics are guided by the legal and professional guidelines. Dutelle (2011) asserts that the morals are
