How To Secure Your Wireless Network

Posted by / in IP Address Tips, Security / No comments yet

Security has become a crucial thing in the lives of many people currently. It is a very dangerous thing to have an unprotected wireless network. This is because any type of information that you send over the wireless network can probably be interrupted by malicious people. Therefore, if you are looking for a way to secure your network, then do not worry. The following are the step by step tutorial on how to secure your wireless network:

Step 1: Access your wireless network router

Wireless network routers are controlled through the administration pages which can be accessed through the web browsers. You only require your router’s IP address. This can always be obtained by looking online or its manual for information on the specific model of your router.

After you have the router’s IP address, you should type it in the URL bar of your browser. You will be required to insert a username and a password. The word admin is often used by default as both username and password even though there are some routers which use admin’ as a username and password’ as a password.

Step 2: Change your default administration username and password

You will want to limit access to the admin page of the wireless router. If an individual was to gain access to your router, they would change the log in details and even lock you out of your network system forever.

Step 3: Change your Service Set Identifier (SSID)

SSID is the name that will be visible for your wireless network every time you look for an open network using a wireless enabled device. In case the SSID of your router is set to default by the manufacturer, any would be able to see it if they are looking for an open network around and with some few online searches, they can find out the model number of your router which will assist them access to the settings of your router easily. Therefore, you need to change you router’s SSID available in the network wireless section in your admin page.

Step 4: Lock your Wi-Fi Network

At this point, you need to navigate to the wireless setup or wireless security section of the admin page of your router.

There are various security alternatives available for wireless network routers. For many users, WPA or WPA2-Personal is the perfect selection. You should never secure your Wi-Fi network using WEP. This is WEP is a very older security protocol which is extremely vulnerable to network attack.

Set both encryption and version techniques to the automatic settings. Thereafter you should set a password that you can easily remember but cannot be guessed by anyone else.

With the above steps your wireless network will be secured and no one would easily interfere or gain access to the system.

iPad Air Apple’s New iPad

Posted by / in Mobile, News, Tech / No comments yet

October 22, 2013 marks the day Apple announced the release of its latest version of the iPad – the iPad Air. Apple stated in its press release that the Wifi-only models of the iPad Air will be available for sale beginning November 1, 2013. Apple users and iPad lovers everywhere may have expected the previous naming conventions of Apple’s tablet to be termed the iPad 5. However, it seems as though Apple chose to market the new iPad Air for its improved design and portability, rather than marketing the device as an improved version of the iPad with Retina Display(also referred to as the iPad 4).

iPad Air Features

The newest feature of the iPad Air is undoubtedly in its design. Apple chose to deliver the iPad Air with a remarkably similar body structure as the iPad Mini. Unlike the iPad with Retina Display or the iPad 2, the iPad Air’s box-like design may have aided in its becoming the most portable 10 inch tablet on the market today. Now, it’s difficult to differentiate the iPad Mini from the full-sized version of the tablet. The iPad is now 20% thinner, 28% lighter, and weighs only 1 pound.

The new iPad Air has also paved the way for tablet processors and power. The mobile device comes with the same A7 processor and M7 coprocessor that is now available in the iPhone 5s. The new M7 processor is the first mobile processor to utilize a 64-bit architecture. Paired with the eye-catching retina display, iPad users can now experience incredible graphics and visual displays with lighting speed.

iPad Air Pricing

The new iPad Air will maintain the same price as its predecessors. One part of the iPad that has remained relatively stable over models is Apple’s consistent pricing structure. The tables below show the suggested retail prices that consumers are likely to encounter when purchasing the new tablet.

Wi-Fi Only Models

Version Price
16GB $499
32GB $599
64GB $699
128GB $799

Wi-Fi + 3G Models

Version Price
16GB $629
32GB $729
64GB $829
128GB $929

Improvements Over the Previous iPad Versions

Processor. iPad users can look forward to the revolutionary A7 processor in the new iPad Air. The A7 processor is the first 64-bit processor for mobile devices, including tablets and smart phones. The new processor also supports OpenGL ES version 3.0. Open GL ES version 3.0 allows the new iPad to produce detailed graphics and visual effects once possible only on desktop computers and game consoles. The faster processor is paired with the M7 coprocessor, which helps to alleviate the load of the device’s peripheral components, such as accelerometer, gyroscope, and compass. This gives the A7 the ability to focus on making apps load faster and gaming more responsive to touch and movement.

Portability. The new iPad Air is the lightest, thinnest tablet currently available. Portability is the one area in mobile device design that Apple continually outshines its would-be competitors. Even with the marginal improvements in performance and functionality, the new iPad continues to boast up to 10 hours of uninterrupted battery use.

Disappointments

No Fingerprint Reader. Many Apple followers may have expected the new iPad to come standard with the same new technology that was released with the new iPhone 5s. However, it seems like the latest version of Apple’s mainstream devices won’t come with the new fingerprint reader. The fingerprint reader is thought of by analysts to potentially revolutionize security if mobile devices.

Same Display. While the retina display was truly an amazing addition to the iPad family, the iPad air shares the identical screen size, specifications, resolution, and pixel density as the iPad 4. It’s unclear why this is the case, when the new iPad Mini with Retina Display boasts a much higher pixel density at 326 pixels per inch(ppi).

Summary of the new iPad Air

The new iPad Air can be compared to Apple’s release of the new iPhone 5s – marginal. Once again this year we’ve seen Apple release a subsequent model of a mobile device that offers little improvement over its predecessor.

ICANN Expands Generic Top-Level Domain Names (gTLDs)

Posted by / in News / No comments yet

ICANN, the Internet Corporation for Assigned Names and Numbers, was founded in 1998 to help organize the management of domain names. ICANN has recently sought to increase the level of domain-related competition on the Internet by authorizing the release of hundreds of new Generic Top Level Domains. It would appear as though the largest domain registrars across the globe are seeking to capitalize on the new domain program. However, what are the benefits of the new program? How harmful are the potential negative impacts?

Current Generic Top-Level Domains

Currently, there are only 22 gTLDs available for use. The largest and most well-known of the gTLDs is .com, a top-level domain that is owned by the Internet giant Verisign, Inc.. Some other well-know top-level domains include the following:

 

  • .aero
  • .asia
  • .biz
  • .cat
  • .com
  • .coop
  • .info
  • .int
  • .jobs
  • .mobi
  • .museum
  • .name
  • .net
  • .org
  • .post
  • .pro
  • .tel
  • .travel
  • .xxx

There are two types of gTLDs: sponsored TLDs (sTLDs) and unsponsored TLDs (uTLDs). The uTLDs are managed using the same policies as those that govern gTLDs. sTLDs are domains that are managed by a sponsor organization. The sponsor organization is responsible for establishing policies and practices for the management of that sTLD. For example, .com, .net and .org are the orginal uTLDs established in the 1980’s. The domains ending in .edu, .gov, .int and .mil are sTLDs. sTLDs are intended to represent a specific community or type of organization, such as a university or government entity.

Future Top-Level Domain Names

Any follower of domain-related news may recognize that many of the domains in the list above were originally intended to be sTLDs, including .mobi and .xxx. However, since 2004, ICANN’s proposed market structure of these new sTLDs has been slightly modified to meet the increase in demand of domain names. As a result, many of the new domains are available to the public via domain registrars, as opposed to their sTLD counterparts such as .edu.

The newest generic Top-Level Domains will provide buyers with the ability to easily identify their websites through the use of the identifier. The new domain names correspond to various industries, using words or abbreviations to specify the community, such as .attorney or .engineer. Some of the domains identified for release by ICANN that are associated with businesses include:

  • .ads
  • .agency
  • .associates
  • .booking
  • .business
  • .career
  • .careers
  • .center
  • .ceo
  • .club
  • .company
  • .ecom
  • .enterprises
  • .farm
  • .forum
  • .gives
  • .gle
  • .global
  • .gmbh
  • .inc
  • .institute
  • .insure
  • .lifeinsurance
  • .llc
  • .llp
  • .ltd
  • .ltda
  • .management
  • .marketing
  • .new
  • .news
  • .ngo
  • .partners
  • .press
  • .sarl
  • .services
  • .solutions
  • .srl
  • .studio
  • .trade
  • .trading
  • .ventures
  • .wiki
  • .xin
  • .اتصالات
  • .企业
  • .公司
  • .商标
  • .集团


In any new expansion, there are those that are proponents and there are those that see only negative outcomes. In the case of new gTLDs, the winners and losers have likely varying opinions on the impact the new domains will have on the Internet industry.

Criticism of the New gTLD Program

Confusion. Critics of the new gTLD program say that the new domains are likely to bring unnecessary confusion among Internet users. More top-level domains mean that there are more possible combinations of words and identifiers, meaning that duplication of content could be an issue. However, it could be that the new domain names bring about just the opposite.

For example, if web surfers use a search engine to find a Wiki-oriented website concerning their favorite music, a .wiki gTLD will likely identify the sites that fit into this criteria. But what happens when the unethical purchase domains with the intent of leading consumers? Let’s say you search for “wiki music”. The top two search engine results end with .wiki and .music. But which one is correct? The bottom line is that there hasn’t been much research on how the new gTLDs will affect search engine optimization. Also, we’re likely to see an increase in branding and trademark lawsuits that have never been seen.

Scale-ability. Proponents of the new gTLD program are excited about the endless possibilities of the new domains. In the past and currently, there has been much profiteering from domain name purchases. This has caused the demand of highly sought-after domains to be parked or left unused while an investor waits for someone to spend much more than the $9.99 spent on the original purchase. With the large number of new domains, it may be easier for new Internet businesses to find and acquire the name that suits their business needs.

Control. In recent years, many domain registrars have relinquished the isolation of their gTLDs in order to capitalize on the monetary benefit of public sales. For example, .me was originally the Internet country code top-level domain (ccTLD) for Montenegro. However, due to the appeal of the English-friendly term, the country of Montenegro awarded doMEn a contract to operate the domain.

Will the same amount of loosely applied control be designated to the new top-level domain names? If so, what will be the impact on user-related confusion? For the time-being, there’s no way to predict the outcome of such a mass-release of domains. However, domain buyers and sellers alike can head to the website of any domain name registrar to be notified of a particular domain’s release.
