WHAT IS HTML(Hypertext Markup Language) ?

WHAT IS HTML(Hypertext Markup Language) ?

HTML (Hypertext Markup Language) is a content based way to deal with depicting how content contained inside a HTML document is organized. This markup advises an internet browser how to show the content, pictures and different types of sight and sound on a site page.

Ordinarily utilized HTML labels.

The part of HTML is to advise an internet browser about how the substance contained inside a HTML record is organized. Normally utilized HTML labels incorporate <H1>, which portrays a best level heading; <H2>, which depicts a second-level heading; <p> to depict a section; <table>, which portrays unthinkable information; and <ol>, which portrays an arranged rundown of data.

As should be obvious from this short rundown, HTML labels basically manage the auxiliary components of a page.

Varieties of HTML.

In the beginning of the internet, increasing content based records utilizing HTML language structure was more than adequate to encourage the sharing of scholastic reports and specialized reminders. Be that as it may, as the web extended past the dividers of the scholarly world and into the homes of the overall public, more noteworthy request was set on website pages as far as arranging and intelligence.

HTML 4.01 was discharged in 1999, when the web was not yet a commonly recognized name, and HTML5 was not institutionalized until 2014. Amid this time, HTML markup floated from the activity of essentially portraying the structure of the substance on a site page into the part of likewise depicting how substance should look when a website page shows it.

Accordingly, HTML4-based site pages regularly included data inside a tag about what textual style to utilize while showing content, what shading ought to be utilized for the foundation and how substance ought to be adjusted.

Portraying inside a HTML label how a HTML component ought to be organized when rendered on a website page is viewed as a HTML anti pattern. HTML ought to portray how content is organized, not how it will be styled and rendered inside a program.

For rendering, the best possible practice is to utilize falling templates (CSS). A HTML document can connection to a falling template, which will contain data about which hues to utilize, which text styles to utilize and other HTML component rendering data. Isolating data about how a page is organized, which is the part of HTML, from the data about how a site page looks when it is rendered in a program, which is the part of a CSS document, is a product advancement example and best practice known as partition of concerns.

Altering HTML illustration.

In the accompanying HTML case, there are two HTML components. The two components utilize a similar section tag, assigned with the letter p, and both utilize the directional characteristic dir, despite the fact that an alternate esteem is relegated to the HTML quality's name-esteem matching, to be specific rtl and lt.
https://www.computersc.xyz
HTML SIMPLE CODE

Notice that when this HTML piece is rendered in a program, the HTML labels affect how every HTML component is shown on the page, however none of the HTML labels or characteristics are shown. HTML just depicts how to render the substance. The HTML itself is never shown to the end client.
https://www.computersc.xyz
OUTPUT

What is very much shaped HTML?

All together for an internet browser to show a HTML page without mistake, it must be furnished with all around framed HTML. To be very much shaped, every HTML component must be contained inside an open tag - <p> - and a nearby tag - </p>. Moreover, any new label opened inside another label must be shut before the containing tag is shut. So <h1><p>well-shaped HTML</p></h1> is all around framed HTML, while <h1><p>well-shaped HTML</h1></p> isn't very much shaped HTML.

HTML language structure guidelines.

Another language structure decide is that HTML characteristics ought to be encased inside single or twofold statements. There is frequently banter about which organize is actually right, however the World Wide Web Consortium attests that the two methodologies are adequate.

"As a matter of course, SGML necessitates that all trait esteems be delimited utilizing either twofold quotes (ASCII decimal 34) or single quotes (ASCII decimal 39)."

The best guidance for picking amongst single and twofold statements is to keep the utilization steady over every one of the reports. HTML style-checkers can be utilized to implement steady use crosswise over pages. It ought to be noticed that occasionally utilizing a solitary statement is required, for example, in an occurrence where a characteristic's esteem really contains a twofold statement character. The switch is valid also.

"Single statement imprints can be incorporated inside the property estimation when the esteem is delimited by twofold statement imprints, and the other way around."

Step by step instructions to utilize and actualize HTML.

Since HTML is totally message based, a HTML record can be altered basically by opening it up in a program, for example, Notepad++, Vi or Emacs. Any content manager can be utilized to make or alter a HTML record and, insofar as the document is made with a .html augmentation, any internet browser, for example, Chrome or Firefox, will be equipped for showing the record as a website page.

For proficient programming engineers, there are an assortment of WYSIWYG editors to create website pages. NetBeans, IntelliJ, Eclipse and Microsoft's Visual Studio give WYSIWYG editors as either modules or as standard parts, making it unimaginably simple to utilize and execute HTML.

These WYSIWYG editors likewise give HTML investigating offices, albeit present day internet browsers frequently contain web engineer modules that will feature issues with HTML pages, for example, a missing end tag or language structure that does not make very much framed HTML.

Chrome and Firefox both incorporate HTML designer devices that take into account the prompt review of a website page's entire HTML record, alongside the capacity to alter HTML on the fly and quickly fuse changes inside the program.

The HTML standard.

HTML is a formal proposal by the World Wide Web Consortium (W3C) and is by and large clung to by all significant internet browsers, including both work area and versatile internet browsers. HTML5 is the most recent rendition of the detail.

WordPress mein redirecting issue ko kaise theek karen?

August 20, 2018 0

Running a self hosted WordPress.org site has a lot of benefits, but at times some easily solveable errors can irritate beginners. White screen of death, Internal server error, and some other common WordPress errors can be really stressing for new users. Recently a user pointed our attention to ‘Too Many Redirects’ error in WordPress. It is a common issue that WordPress users may come across. In this article, we will show you how to fix error too many redirects issue in WordPress.

On Firefox, this error will be displayed like this:

“The page isn’t redirecting properly. Firefox has detected that the server is redirecting the request for this address in a way that will never complete.”

WordPress redirect error displayed in Firefox

Why I am Getting Error Too Many Redirects in WordPress?

This error usually occurs due to a misconfigured redirection issue. As you know that WordPress has SEO friendly URL Structure which uses the redirect function. Several other popular WordPress plugins also use the redirect functionality. For example, WordPress SEO plugin allows you to remove category base from category URLs by redirecting users to a URL without category base. WordPress SSL and cache plugins also use redirects.

Due to a misconfiguration in any of these redirection tools, your site may end up redirecting users to a URL that is actually redirecting them back to the referring URL. In that case the user’s browser is trapped between two pages and hence you see the error.

Error too many redirects as shown in Google Chrome

How to Solve Too Many Redirects Error in WordPress?

The most common misconfiguration that we have come across repeatedly is when a user has incorrect URL in WordPress Address URL or Site Address URL settings.

WordPress and Site Address settings

For example, lets assume that your site’s url is http://www.example.com and you go to Settings » General and set it to http://example.com. Most web hosts allow you to choose whether you would like to add a www prefix to your domain name or have it without www. In case you had selected to add www to your URL, then adding http://example.com in your WordPress settings will cause the error. Or if you opted to use your domain without www prefix, then adding it with www prefix in WordPress settings will cause this error.

When a user will come to http://example.com, they will be redirected by your server’s configuration to http://www.example.com where they will be redirected back to http://example.com by WordPress because that’s what you have set up in the settings.

If your site was working fine, and you you did not make any changes to those settings. Then you need to contact your web host, because it is most probably a configuration issue at their end.

However, if you do not have a reliable WordPress hosting provider, and they deny having any issues and/or refuse to help you, then you should consider switching web hosts or fix it yourself.

To fix this, you need to change your WordPress Address and Site Address. Go to Settings » General, change your WordPress and Site Address. If you have your address with www prefix, then change it to non-www URL, and if you have it with non-www URL then add the www prefix.

Important: Make sure that you don’t leave a trailing slash at the end of your URL like http://www.example.com/

Change Site URL Without Access to Admin Area?

In case you don’t have access to WordPress Admin area, you can still update these settings by defining them in wp-config.php file. Simply connect to your website using an FTP client. Once you are connected to your site, you will find wp-config.php file in your site’s root directory. You need to download and edit this file using a text editor like Notepad. Simply add these two lines to the file and don’t forget to replace example.com with your own domain.

1

2

define('WP_HOME','http://example.com');

define('WP_SITEURL','http://example.com');

Save the file and upload it back to your web server. Now try to access your WordPress site. If you still can not access your site, then try to add your domain with www prefix.

Fixing Other Redirect Issues?

If the previous step did not solve your problem, then it is likely that there is a plugin issue with your site. As we mentioned earlier that several WordPress plugins use redirection techniques to do a variety of things. We will try to help you troubleshoot.

First you need to figure out is which plugin is causing the issue. Did you activate a new plugin recently right before this error happened? Did you update plugins right before this error happened? If the answer to any of the above questions is YES, then it narrows the problem down to that plugin. You can simply deactivate that plugin by deleting that plugin’s folder from wp-content/plugins/

If you do not know which plugin is causing the issue, then you would need to do some trial and error. The quickest way to do this is by deactivating all plugins. After deactivation of all plugins on your site, you need to use FTP to download the .htaccess file as a backup. You can find this file in your site’s root directory. Once you have downloaded the file, delete it from your server. Now try to access your site.

This process will allow your server to regenerate a new .htaccess file, and since there are no plugins activated, it will most likely fix the issue. If the error is gone now, then you know for certain that it was a plugin causing this error.

The next step is to find out which plugin was the culprit. To do this, you need to download and install fresh copies of all your plugins. Activate plugins one at a time and after activating each plugin try to browse several pages on your site using a different browser as a non-logged in user. Hopefully you will find the plugin that caused the issue.

These are all the possible solutions that may fix this “error too many redirects issue” in WordPress. Did any of the above solutions fixed the problem for you? If so, then please let us know in the comments. Have you encountered the error too many redirects issue in the past? how did you fix it?

computer virus 

वर्तमान में सामान्य कंप्यूटर user के कंप्यूटरों में वायरस के कारण समस्या उत्पन्न होती रहती है ! इस के कारण कभी कंप्यूटर स्क्रीन पर विभिन प्रकार की अक्रती या चिन्ह प्रदर्शित होते रहते है , अथवा कंप्यूटर अन्दर ही अन्दर कुछ प्रोग्रमिंग  करते रहते है , जिस के कारण user को अपने डेटा को खोना पड़ता है ,और जिस से user हार्ड डिस्क में से डेटा को एक्सेस नही कर पता है !

what is computer virus

कंप्यूटर virus कुछ निर्दाशो का ऐसा शक्तिशाली प्रोग्राम होता है , जो अपने तरीके से कंप्यूटर को चलता है ,ये virus किसी भी समान्य कंप्यूटर से जुड़ जाता है ! कंप्यूटर virus का प्रमुख कार्य केवल कंप्यूटर मेमोरी से डेटा को ख़त्म destroy करना होता है तथा सम्पर्क में आने वाले सभी प्रोग्रामो को संक्रमित करना होता है , तथा virus कंप्यूटर प्रणाली को बन्द कर देता है ! 

History of virus 

बतया जाता है की पाकिस्तान में रहने वाले दो भाइयो ने virus प्रोग्राम बनाया था ,उन दोनों ने सी - अशर सी -ब्रेंन नाम के virus बनये थे ,इन दोनों में से सब से चर्चित         सी -ब्रेंन रहा था !

13 Secret Codes That Unlock Hidden Features on Your Phone

13 Secret Codes That Unlock Hidden Features on Your Phone

The USSD protocol allows you to access hidden features you didn't know about right from your smartphone's dialer. But there is some trickiness you'll need to know about.

Remember that scene in War Games when the socially broken code monkeys were explaining to aspiring hacker Matthew Broderick all about "back doors" (i.e. secret pathways planted by programmers)? Well, that's actually a thing.
Coders have a storied tradition of baking in secret passageways (or sometimes, just fun little Easter eggs) that can only be accessed by inputting a special "key." And so that tradition continues in the mobile age.
Unstructured Supplementary Service Data (USSD)—sometimes known as "quick codes" or "feature codes"—is an extra-UI protocol, which allows people to access hidden features. This protocol was originally created for GSM phones, but can be found on CDMA devices as well (if that's a bunch of acronym gibberish to you, here's a quick primer).
READ: 15 Cool Tricks You Didn't Know Your Phone's Camera Could Do
These publicly available backchannels allow users to directly communicate with their service provider's computers and/or access back-end features in their device. They are accessed by inputting them into the phone's dialer (the screen you use to start a phone call) and usually begin and end with the * or # keys with a sequence of numbers in between (there's close-to-zero chance that anyone would accidentally access them).
They're not terribly practical. Most people don't really need to know how their local cell towers are performing or what their IMEI number is (more on that later). Still, it can be fun to play around and see what unexpected functionality your phone is hiding beneath the surface.
We would LOVE to provide you with a comprehensive list of the dozens of codes out there, but that would be an exercise in futility. These codes seldom work across different carriers, OSes, or phone models (or even on generations of the same model).
If you really want to try them out, your best bet may be to Google your phone's make and carrier + "USSD" for a tailored, comprehensive list. I attempted a number of codes using an iPhone SE (while trading out numerous carrier SIM cards) in addition to a Galaxy S5 and Galaxy S7 Edge running on AT&T. Some of them worked! Check out the list below for 13 codes that I can confirm worked on at least one device. Good luck and have fun!
  • Field Mode: *3001#12345#*

    1 Field Mode: *3001#12345#*

    Type *3001#12345#* into your phone's dialer and then press the green call button to access "Field Mode," which can give you access to info about local networks and cell towers.


    You'll probably never ever have to know about your local cell tower's "Measured RSSi," but it's fun to look around for a bit.

  • General Test Mode: *#0*#

    2 General Test Mode: *#0*#

    I could only get this to work on Android. But this prompts a library of different phone operations, which could be operated with a single push (e.g. Sleep, Front Cam, Vibration).

  • Display your IMEI: *#06#

    3 Display your IMEI: *#06#

    Here's a code which I found out does not work with Verizon on an iPhone, but I could make it work after switching to a T-Mobile SIM. It also worked on my Android AT&T device as well. To access it, type in the above code, and then the green call button to prompt your IMEI number (or your International Mobile Station Equipment Identity number, but you already knew that).


    The IMEI is unique to your device. Among other things, the number can help "blacklist" stolen devices or help with customer support.

  • Check Your Call Forwarding: *#67#

    4 Check Your Call Forwarding: *#67#

    This code allows you to check which number your phone is currently forwarding calls to when you're busy or reject a call.


    By default, this is probably your carrier's voicemail service, but you can change it to forward to a different number (a home number, office number, or third-party answering service for example). On an iPhone, you can change this number by going to Settings > Phone > Call Forwarding. On Android (varies from system to system), tap the Phone app > hamburger icon > Settings > Call > More Settings > Call forwarding


  • Get Even More Info on Call Forwarding: *#61#

    5 Get Even More Info on Call Forwarding: *#61#

    On my Galaxy phone, this code prompted a pop-up that let me know how long until a call is forwarded to the message center. On the iPhone, regardless of carrier, this code just showed me the same info as *#67# .

  • Check Your Available Minutes: *646#

    6 Check Your Available Minutes: *646#

    Apparently this one only works on postpaid plans. I was not able to get it to work on my test iPhone (regardless of carrier; I tried three), but I did get it to work on my Galaxy phone (which happens to have an unlimited texting plan from AT&T). Instead of showing the info on a new screen, it sent my phone a text message.

  • Check Your Bill Balance: *225#

    7 Check Your Bill Balance: *225#

    Once again, I couldn't get this one to work on the iPhone, but on Android I did get it to prompt a SMS message with my current balance due.

  • Hide Your Phone From Caller ID: #31#

    8 Hide Your Phone From Caller ID: #31#

    I could only get this to work on Android. But entering this code prompted a pop-up stating that my Caller ID had been disabled. In order to re-instate Caller ID, enter *31# .


  • Check Your Billing Cycle: *3282#

    9 Check Your Billing Cycle: *3282#

    Once again, I could only get this to work on Android. It prompted an SMS message with my billing info.

  • SMS Message Center: *5005*7672#

    10 SMS Message Center: *5005*7672#

    This code will tell you your SMS message center number. I have no idea why you'd need that info, but there ya go.

  • Activate Call Waiting: *43#

    11 Activate Call Waiting: *43#

    This code will activate call waiting; you can deactivate it by entering #43#.

  • Quick Test Menu (Samsung Galaxy Only) *#7353#

    12 Quick Test Menu (Samsung Galaxy Only) *#7353#

    As far as I can tell, this code only works on Samsung Galaxy models (I tested it on my Galaxy S7 Edge). This is similar to the General Test mode mentioned earlier, in that it brings up a menu with a number of one-tap test prompts.


    The first test is "Melody," which prompts a jaunty little K-Pop diddy. I don't know who the artist is (it's un-Shazammable!), but a search of the lyrics pointed me to this YouTube clip, with a title that translates to "Samsung Anycall Galaxy basic level - Hey Now (Good bye)." If you have any details on this mobile mystery, drop it in the comments.


  • Firmware (Samsung Galaxy Only) *#1234#

    13 Firmware (Samsung Galaxy Only) *#1234#

    Once again, as far as I can tell, this only works on Galaxy devices. But it will let you know your phone's current firmware. So, have fun with that.
