Wi-Fi Explained (Part 1)

Posted on Posted in computer, gadget, internet, technology

About Wi-Fi

Wi-Fi is known as Wireless Fidelity. Wi-Fi allows network connectivity through radio signals without the need for wires. "Wi-Fi Alliance" suggesting the term Wi-Fi. Wi-Fi term is also used as a synonym for any type of 802.11 networks.

About Radio Waves

Radio waves are the longest wavelength waves in the electromagnetic spectrum. The length ranges from the size of a football field to the size of a volley ball. Radio waves carry signals to your radio, TV, mobile, etc.

Access Point Defined

Access Point is the configured node on wireless local area network (WLAN). Access points act as a central receiver and transmitter of WLAN radio signals. Access points are dedicated hardware devices, which consist of antenna, radio transmitter, and built-in network adapter.

Hotspots Explained

Hotspot is an area serviced by an access point which allows Wi-Fi clients to connect to a network. Hotspots are those areas where Wi-Fi is provided on demand. Since Wi-Fi has gained acceptance in many businesses, homes, etc, and nowdays most of the laptops and electronic devices are having inbuilt Wi-Fi access devices; Wi-Fi can act as an alternative to a wired LAN. Places like airports, star hotels, caf├ęs, etc, are the locations where Wi-Fi is available on demand. The places where Wi-Fi is available on demand or free are also known as hotspots.

Wi-Fi & Hotspots

The area covered by one or more interconnected Access Points is called a "Hotspot". The space range Hotspots can cover variants from as little as a single room with wireless-opaque walls or as much as many square miles covered by overlapping access points. Wi-Fi can also be used to create a mesh network. Wi-Fi allows connectivity in peer-to-peer mode, which enables devices to connect directly with each other. This connection mode is useful in consumer gaming and electronics applications.

Certification Issue

When Wi-Fi technology was first commercialized, there were many problems regarding the interaction between different Wi-Fi gadgets. Then a community called "Wi-Fi Alliance" began to solve this issue, also addressed the needs of the end user, and allowed the technology to mature. The Alliance's "Wi-Fi Certified" stamp on Wi-Fi enabled gadgets assures consumers that the stamped products are interoperable amongst each other. Wi-Fi also enables wireless voice applications (VoWLAN or WVOIP). "Wi-Fi Certified" products interact among each other although their manufacturers are different. A "Wi-Fi" certified product can use any brand of access point with any other point of client hardware which is also "Wi-Fi" certified. Any "Wi-Fi" product will work with any non "Wi-Fi" certified product, if the latter uses the same radio frequency as the former.

SSID & its Purpose

Expansion of SSID is Service Set IDentifier. It is a code that attaches to all packages on a wireless network; only to identify each packet as part of that network. The code consists of case-sensitive alphanumeric characters. Wireless devices that attempt to communicate with each other must share the same SSID. The process of connecting a device to a specific wireless network through …

How the Internet is Changing the Way We Communicate

How the Internet is changing the English language and the ways we speak

As a linguist and an ex-English teacher, the evolution of language has always fascinated me. Since the 15th century, the English language has evolved under the influence of technology but I would argue that this has been more in terms of style than structural changes to the language. The first big change came in the 15th century with the use of printing presses which introduced new standardized grammar, spelling and punctuation styles. In the 19th century, telephonyrought in new patterns of dialogue as people could speak to each other at greater distances. Radio and TV broadcasting in the early 20th century introduced us to new styles and thought us sports commentators, chat shows and interviews. However, it is the internet that has had a massive change both in the way we speak and how we write English.

Who could have predicted that internet technology would have brought us so much diversity? For example, just think of the different technologies and the way we communicate in English using these technologies:

* the world wide web itself

* email

* chat rooms

* instant messaging

* the virtual worlds of games

* blogging

* twittering

* mobile phone texting

* social Networking

We do not speak or communicate in the same way when we are blogging as when we are texting and each technology has its own style of the English language. These different styles of communication have exploded and will continue to evolve and you can see it in all forms of online marketing or offline marketing materials

Whilst the internet has produced some new vocabulary or "internet slang", there are only a few hundred new English slang words in a language which has over one million words. So the 20th century slang of "groovy" and "funky" has given way to phrases like "lol" (laugh out loud), and "brb" (be right back) in the 21st century – but they are still relatively few.

So, although there are some new punctuation formats, eg emoticons, there have been no significant changes to grammar patterns or verb endings. The main change has been the style of language that we use when we communicate.

Lots of purists and people would like to preserve the correct way to speak English. However, no one can stop trends in style and slang from changing the way we communicate. Whether it is cave men's drawing on walls, writing in sand with a stick, or sending a "tweet" to the other side of the world, the English language is something that will never be permanent and will be constantly changed by technology. …

Future Shock: Voice Recognition Identification Technology

Posted on Posted in technology

Backgrounder: Kay Hughes, flight attendant for today’ s non-stop coast-to-coast flight is busy checking her catering order and prepping the cabin. Bob Harmon is the captain and Jeff Mortowski is his first officer. Both are situated in the cockpit going over the pre-flight checklist. The pax are from various companies in the New York area or individuals on personal business who have bought seats on his flight.

The Story: Kay woke up with a start as the alarm on her clock radio blared. Reaching across her pillow, she noticed the time, 5:15, and hammered the snooze button in the hopes of grabbing another five minutes of sleep. Tired as she was, her mind began to race as she considered the day ahead. In less than four hours she would be enroute to L.A. with an aircraft full of passengers. Slowly the thought of additional sleep became less important as she considered all that she had to do before leaving Teterboro. Quietly she slipped on her robe and slippers, poured herself a cup of coffee, and slinked into the shower.

As Kay walked across the tarmac, she saw the fuel truck pulling up to her aircraft and the caterer at the gate waiting for a security clearance. It was 6:48 and already she could feel the heat lifting off of the pavement. Another scorcher she thought; at least L.A. will be cooler.

Kay greeted Jeff who was busy overseeing the fuel delivery; she then climbed onboard the G-V and gave a similar greeting to Bob who was occupied with updating paperwork. Bob finished what he was doing and briefed Kay with the day’s schedule. Minutes later Kay turned to assist the approaching caterer with the day’s order. Within the hour, the first of the passengers began to arrive. Each sat in the lobby of the FBO waiting to be boarded. At precisely 8:00 a.m., Kay left the aircraft and walked down the ramp to the FBO. She whispered to the waiting security agent who signaled to the FBO customer service representative to make the boarding announcement. “Ladies and Gentlemen, Jet Aviation Flight #001 departing TEB for LAX is now boarding. Please present your identification card and boarding pass to the security agent. Once you are cleared, you will be boarded. Thank you for flying Jet Aviation and enjoy your flight.”

Kay turned and left the FBO and walked back to the aircraft. Both pilots were onboard completing their preflight preparations. Kay stood at the bottom of the steps leading up to the aircraft waiting for the security agent to bring the passengers to the plane. She knew that with fourteen passengers the security clearance would take a bit longer than normal.

Kay considered waiting inside the cabin to keep cool, but knew that it was important that she greet the passengers at the base of the steps in case one of them needed assistance climbing up.” It must already be 85 degrees out here,” she thought as she watched the heat …

Does Technology Benefit Young Children’s Education?

Posted on Posted in computer, internet, technology

As parents, all of us have fought the battle with our kids as they are absorbed into a video game or movie on an iPad, tablet or smartphone. We’ve had a better chance of getting the attention of Tom Cruise walking the red carpet than our kids.

Today, it’s common for two-year-olds to be using iPads, elementary schoolers hooked up to video games, and we all suffer (or live with) the challenge of prying your middle-schooler away from the computer long enough to eat a decent meal…

Technology is everywhere and its draw on kids is obvious, but is technology helping our kids learn?

Technology is becoming more social, adaptive, and customized, and as a result, it can be a fantastic teaching tool. That stated, as parents, we need to establish boundaries.

Today, software is connecting kids to online learning communities, tracking kids’ progress through lessons and games, and customizing each students’ experience.

By the time your child is in elementary school, they will probably well-versed in technology.

Learning with Technology at School

Schools are investing more and more in technology. Whether your child’s class uses an interactive Smartboard, laptops, or another device, here are three ways to make sure that technology is used effectively.

Young children love playing with technology, from iPads to digital cameras. What do early childhood practitioners – and parents, too – need to think about before handing kids these gadgets?

Let’s start at the beginning: what is technology in early childhood?

Technology can be as simple as a camera, audio recorder, music player, TV, DVD player, or more recent technology like iPads, tablets, and smartphones used in child care centers, classrooms, or at home.

More than once, I’ve had teachers tell me, “I don’t do technology.” I ask them if they’ve ever taken a digital photo of their students, played a record, tape, or DVD, or give kids headphones to listen to a story.

Teachers have always used technology. The difference is that now teachers are using really powerful tools like iPads and iPhones in their personal and professional lives.

Technology is just a tool.

It shouldn’t be used in classrooms or child care centers because it’s cool, but because teachers can do activities that support the healthy development of children.

Teachers are using digital cameras – a less flashy technology than iPads – in really creative ways to engage children in learning. That may be all they need.

At the same time, teachers need to be able to integrate technology into the classroom or child care center as a social justice matter.

We can’t assume that all children have technology at home.

A lack of exposure could widen the digital divide – that is, the gap between those with and without access to digital technology – and limit some children’s school readiness and early success.

Just as all children need to learn how to handle a book in early literacy, they need to be taught how to use technology, including how to open it, …

Steps to Becoming a Great Website Designer

Posted on Posted in programming, technology, website

Many individuals may have entry level web designer skills, especially as so many now complete their own design projects, including everything from the creation of personal blogs to family-related or business-driven websites. The working knowledge of the web that the average younger person contains within his or her mind is impressive; however, the process of becoming a professional level designer is significantly more complex than most people realize.

Do not mistake the skills you have as being the only ones of merit in obtaining designer jobs. Even if you have achieved a significant degree of knowledge and skills within the web design field, there is always so much more that you can learn. And with the ever-changing and constantly advancing technologies in the IT and web design industries, you'll never run out of new things to learn or new challenges to meet, even after completing a formal education and years of practical work experience.

Many younger people understand the basics of HTML, though few have advanced HTML skills. Learning the ins and outs of higher level HTML, including frames and tables, DHTML, style sheets and other skills, is part of what is achieved through undergraduate programs with technical schools, colleges and universities.

Most web designer jobs with reputable firms require a minimum of a bachelor's degree. You will need to master not only HTML but many other cruel design and programming skills. Although web designers primarily focus on the appearance and character of the website design, it is possible to merge programming and design skills and, in fact, some of the most highly thought after designers are those who are both designer and programmer.

The ability to complete the seen and unseen parts of a website design makes you a more highly valued employee in many instances. Employers are happy to have both skill sets in one individual, especially as this means that the designer / programmer is able to fully integrate all of the aesthetic and technical elements of a webpage in a cohesive, beautiful, and fully-functional manner.

As more and more businesses are taking advantage of newer technologies, it is becoming even more important that those working in web designer jobs understand how to create web content that can transfer easily and attractively to other formats. As the multimedia focus in digital design continues to expand, designers with multiple skill sets will be even more highly valued in the future job market.

A formal education in the field is only the first step to obtaining jobs in the web design industry. Since the technology and methodology of web design is ever changing, much of your learning in the field will occur on the job. For this reason, practical, real world experience in design and programming is also quite highly valued by employers. Part-time jobs, hobby designing, and internships – whether paid or unpaid – are all legitimate ways to gain practical experience before obtaining any full-time web designer jobs. …

Why Is My Website Not Ranking? 4 Common Indexing Issues Websites Face

Posted on Posted in technology, website

Small business owners all over the country understand the importance of ranking on the first page of major search engines like Google, Yahoo, and Bing. Some have had their websites for years, but remain essentially invisible with exception to searches related to their business name or domain name. In this article we will discover 4 common indexing issues that websites face that make it impossible to rank well online.

Frames – Frames are web pages that show multiple pages at the same time on a browser. To know whether your website is in frames or not take a look at these factors.

o Usually the home page sets the "frame set" for the layout of the web page including the header, menu, content, and footer.

o Within the frame is the main content of each page

o When and page is clicked the URL remains the same regardless of what page is clicked.

For example, example.com has five pages. These pages include:

Home Services Prices Testimonials Contact

In this example, regardless of what page of this site that you click on the URL remains to be example.com.

The biggest problem with frames is that search engines have a problem determining where a page ends and the other begins. If the home page is indexed the search engine finds it difficult to determine home much content is from the home page. Sometimes internal page are indexed with no menu systems, footers, and etc. There are ways to work around this, but for the most part, frames are difficult to rank on search engines.

Flash – Flash files have been a problem for search engines to read through for years. Recent technology has made it easier to decipher words within flash content. Google has announced that they are now able to read through some flash elements . However, that is not to say that a flash website will perform just as well as a text based website. For the best results using flash, limit your flash to your header or menu.

Pictures & Video – A small business website is not a website without pictures or videos, however many people are surprised when I tell them that search engines can not see their pictures or their videos. Some websites consists of a few pictures, a few words and a video. The problem is that unless you specifically let search engines know what the picture is, or explain what this video is about you leave the search engines in the dark. In turn, your website is not included in search results. Remember to include "Alt text" for every image on your website describing the image. For video, video services like YouTube, and Vimeo will allow you to upload your videos with a description of what the video is about.

Duplicate Content – Many websites have the same Title, Meta Description, and Keywords for every page of their website. Every page of your website should have a unique Title, Description, and Keywords that describes …
