Professional Web Design Tips for a Faster Website

In today's time-crunched world, most people literally don't have a minute to spare. This hurried pace extends to the realm of website design -- your professional Web design must satisfy the demands of users with a wide range of options for viewing the Web.
Even if you create a website design that's worth a wait, visitors faced with slow download speed aren't likely to stick around. So how can you make sure that time is on your side? Pay close attention to seven professional Web design tips to create a website that won't slow your business down.
Limit use of flash
Flash is a classic example of style over substance and, while it definitely has its place in professional Web design, it must be used sparingly when you create a website. Even if your visitors have the right flash player (and many won't), it will increase your site's download time. Flash is also one of the Web site design elements that is not yet accessible to search engines, which means it can only hinder your search engine optimization efforts.
Compress your images
Images are a great example of how looks can be deceiving in professional Web design. You might not realize just how much space they occupy when you create a website design. By compressing your images before adding them to your professional Web design, you can reduce/shrink a GIF or .JPEG image by up to half its original size. You may also want to specify the height and weight of your images in your HTML, which can decrease loading time.
Clean up your code
While HTML text is much faster than graphic text, there are ways you can make it even faster. Watch out for extraneous HTML coding – like spaces, unnecessary tags and even white space -- that can increase the size of your files. Remember that less is more, and use defaults for tags or remove them wherever possible.

What is Ecommerce - an overview ?

In its simplest form ecommerce is the buying and selling of products and services by businesses or consumers over the World Wide Web.



Often referred to as simply ecommerce (or e-commerce) the phrase is used to describe business that is conducted over the Internet using any of the applications that rely on the Internet, such as e-mail, instant messaging, shopping carts, Web services, UDDI, FTP, and EDI, among others. Electronic commerce can be between two businesses transmitting funds, goods, services and/or data or between a business and a customer.

People use the term "ecommerce" or "online shopping" to describe the process of searching for and selecting products in online catalogues and then "checking out" using a credit card and encrypted payment processing. Internet sales are increasing rapidly as consumers take advantage of

lower prices offered by vendors operating with less margin than a bricks and mortar store

greater convenience of having a product delivered rather than the cost of time and transport and parking of going to a store
sourcing product more cheaply from overseas vendors
great variety and inventory offered by online stores
comparison engines that compare and recommend product
auction sites, where they did for goods

What is a sitemap and Why Use a Sitemap for website?

What is a sitemap?

 A sitemap is a file where you can list the web pages of your site to tell Google and other search engines about the organization of your site content. Search engine web crawlers like Googlebot read this file to more intelligently crawl your site.

Also, your sitemap can provide valuable metadata associated with the pages you list in that sitemap: Metadata is information about a webpage, such as when the page was last updated, how often the page is changed, and the importance of the page relative to other URLs in the site.

If your site’s pages are properly linked, our web crawlers can usually discover most of your site. Even so, a sitemap can improve the crawling of your site, particularly if your site meets one of the following criteria:

Your site is really large. As a result, it’s more likely Google web crawlers might overlook crawling some of your new or recently updated pages.


Your site has a large archive of content pages that are isolated or well not linked to each other. If you site pages do not naturally reference each other, you can list them in a sitemap to ensure that Google does not overlook some of your pages.


Your site is new and has few external links to it. Googlebot and other web crawlers crawl the web by following links from one page to another. As a result, Google might not discover your pages if no other sites link to them.


Your site uses rich media content, is shown in Google News, or uses other sitemaps-compatible annotations. Google can take additional information from sitemaps into account for search, where appropriate.

Why Use a Sitemap
Using sitemaps has many benefits, not only easier navigation and better visibility by search engines. Sitemaps offer the opportunity to inform search engines immediately about any changes on your site. Of course, you cannot expect that search engines will rush right away to index your changed pages but certainly the changes will be indexed faster, compared to when you don't have a sitemap.


Also, when you have a sitemap and submit it to the search engines, you rely less on external links that will bring search engines to your site. Sitemaps can even help with messy internal links - for instance if you by accident have broken internal links or orphaned pages that cannot be reached in other way (though there is no doubt that it is much better to fix your errors than rely on a sitemap).

If your site is new, or if you have a significant number of new (or recently updated pages), then using a sitemap can be vital to your success. Although you can still go without a sitemap, it is likely that soon sitemaps will become the standard way of submitting a site to search engines. Though it is certain that spiders will continue to index the Web and sitemaps will not make the standard crawling procedures obsolete, it is logical to say that the importance of sitemaps will continue to increase.

Sitemaps also help in classifying your site content, though search engines are by no means obliged to classify a page as belonging to a particular category or as matching a particular keyword only because you have told them so.

Having in mind that the sitemap programs of major search engines (and especially Google) are still in beta, using a sitemap might not generate huge advantages right away but as search engines improve their sitemap indexing algorithms, it is expected that more and more sites will be indexed fast via sitemaps.

Generating and Submitting the Sitemap

The steps you need to perform in order to have a sitemap for your site are simple. First, you need to generate it, then you upload it to your site, and finally you notify Google about it.

Depending on your technical skills, there are two ways to generate a sitemap - to download and install a sitemap generator or to use an online sitemap generation tool. The first is more difficult but you have more control over the output. You can download the Google sitemap generator from here. After you download the package, follow the installation and configuration instructions in it. This generator is a Python script, so your Web server must have Python 2.2 or later installed, in order to run it.

The second way to generate a sitemap is easier. There are many free online tools that can do the job for you. For instance, have a look at this collection of Third-party Sitemap tools. Although Google says explicitly that it has neither tested, nor verified them, this list will be useful because it includes links to online generators, downloadable sitemap generators, sitemap plugins for popular content-management systems, etc., so you will be able to find exactly what you need.

After you have created the sitemap, you need to upload it to your site (if it is not already there) and notify Google about its existence. Notifying Google includes adding the site to your Google Sitemaps account, so if you do not have an account with Google, it is high time to open one. Another detail that is useful to know in advance is that in order to add the sitemap to your account, you need to verify that you are the legitimate owner of the site.

Currently Yahoo! and MSN do not support sitemaps, or at least not in the XML format, used by Google. Yahoo!allows webmasters to submit “a text file with a list of URLs” (which can actually be a stripped-down version of a site map), while MSN does not offer even that but there are rumors that it is indexing sitemaps when they are available onsite. Most likely this situation will change in the near future and both Yahoo! and MSN will catch with Google because user-submitted site maps are just a too powerful SEO tool and cannot be ignored.

You can learn how to create indices and more about sitemaps at sitemaps.org.

After you’ve created your sitemaps (and potentially sitemap indices), you’ll need to register them with the various search engines. Both Google and Bing encourage webmasters to register sitemaps and RSS feeds through Google Webmaster Tools and Bing Webmaster Tools.
Taking this step helps the search engines identify where your sitemap is — meaning that as soon as the sitemap is updated, the search engines can react faster to index the new content. Also, content curators or syndicators may be using your RSS feeds to automatically pull your content into their sites.

Registering your sitemap (or RSS feed) with Google and Bing gives the search engines a signal that your content has been created or updated before they find it on the other sites. It’s really a very simple process with both engines. 

To submit a sitemap to Google:
  1. Ensure that the XML Sitemap is on your web server and accessible via its URL.
  2. Log in to Google Webmaster Tools.
  3. Under “Crawl,” choose “Sitemaps.”
  4. Click on the red button in the upper right marked “Add/Test Sitemap.” Enter the URL of the sitemap and click “Submit Sitemap.”
To register a sitemap with Bing:
  1. Ensure that the XML Sitemap is on your web server and accessible via its URL.
  2. Log in to Bing Webmaster Tools.
  3. Click on “Configure My Site” and “Sitemaps.”
  4. Enter the full URL of the sitemap in the “Submit a Sitemap” text box.
  5. Click “Submit.”
Another great reason to register sitemaps with Google specifically is to catch Sitemap errors. Google Webmaster Tools provides great information about the status of each Sitemap and any errors it finds:

What’s A Domain Name and Web Hosting ?

What’s A Domain Name
When you register a domain, it gives you sole ownership and rights to the name of your site. No one else in the market has the access to the actual name of that particular domain besides you.
However, just because you have a domain does not mean that you are ready to serve your website to the world. To put up and operate a website, you will need a domain name, and a proper-configured web server (hosting).  (1) a domain name is like your house address; and, (2) a domain name can be registered only with a domain registrar.

For Example:
We like to use the "Car / Garage / DMV" analogy.
Your domain is like the license plate for your car. With it, you can be identified and located on the world wide web.
You can't get a license plate for your car until you register it, nor can you have a domain until you register it, either.

A domain registrar is like the DMV of the internet. You use a registrar to register your domain for a period of time - 1, 2, 5 or more years.
Once you have registered your domain, you need a place to park it - a "garage". A web host is where you do that.
Now that you have registered your domain, and have a place to host it, you need to set up your website - your "car" - for all the world to see.

Website - Car
Registrar - DMV
Domain Registration - Registration
Domain - License Plate
Web Host - Garage

What’s A Web Hosting
A web hosting normally refers to the web server (big computer) that stores lots of data files).

A web hosting providers normally rent out web servers and network connection to the end-users or the resellers. For most cases, the hosting providers will be the parties handling most server maintenance work (such as backup, root configuration, maintenance, disaster recoveries, etc); but for certain cases, the end users will need to get everything cover by themselves.

Types of hosting"

Smaller hosting services

The most basic is web page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a Web interface. The files are usually delivered to the Web "as is" or with minimal processing. Many Internet service providers (ISPs) offer this service free to subscribers. Individuals and organizations may also obtain Web page hosting from alternative service providers.

Free web hosting service is offered by different companies with limited services, sometimes supported by advertisements, and often limited when compared to paid hosting.

Single page hosting is generally sufficient for personal web pages. Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting often has a higher expense depending upon the size and type of the site.

Larger hosting services

Many large companies that are not Internet service providers need to be permanently connected to the web to send email, files, etc. to other sites. The company may use the computer as a website host to provide details of their goods and services and facilities for online orders.


A complex site calls for a more comprehensive package that provides database support and application development platforms (e.g. ASP.NET, ColdFusion, Java EE, Perl/Plack, PHP or Ruby on Rails). These facilities allow customers to write or install scripts for applications like forums and content management. Also, Secure Sockets Layer (SSL) is typically used for websites that wish to keep the data transmitted more secure.
  • Shared web hosting service: one's website is placed on the same server as many other sites, ranging from a few sites to hundreds of websites. Typically, all domains may share a common pool of server resources, such as RAM and the CPU. The features available with this type of service can be quite basic and not flexible in terms of software and updates. Resellers often sell shared web hosting and web companies often have reseller accounts to provide hosting for clients.
  •  
  • Reseller web hosting: allows clients to become web hosts themselves. Resellers could function, for individual domains, under any combination of these listed types of hosting, depending on who they are affiliated with as a reseller. Resellers' accounts may vary tremendously in size: they may have their own virtual dedicated server to a colocated server. Many resellers provide a nearly identical service to their provider's shared hosting plan and provide the technical support themselves.
  •  
  • Virtual Dedicated Server: also known as a Virtual Private Server (VPS), divides server resources into virtual servers, where resources can be allocated in a way that does not directly reflect the underlying hardware. VPS will often be allocated resources based on a one server to many VPSs relationship, however virtualisation may be done for a number of reasons, including the ability to move a VPS container between servers. The users may have root access to their own virtual space. Customers are sometimes responsible for patching and maintaining the server (unmanaged server) or the VPS provider may provide server admin tasks for the customer (managed server).
  •  
  • Dedicated hosting service: the user gets his or her own Web server and gains full control over it (user has root access for Linux/administrator access for Windows); however, the user typically does not own the server. One type of dedicated hosting is self-managed or unmanaged. This is usually the least expensive for dedicated plans. The user has full administrative access to the server, which means the client is responsible for the security and maintenance of his own dedicated server.
  •  
  • Managed hosting service: the user gets his or her own Web server but is not allowed full control over it (user is denied root access for Linux/administrator access for Windows); however, they are allowed to manage their data via FTP or other remote management tools. The user is disallowed full control so that the provider can guarantee quality of service by not allowing the user to modify the server or potentially create configuration problems. The user typically does not own the server. The server is leased to the client.
  •  
  • Colocation web hosting service: similar to the dedicated web hosting service, but the user owns the colo server; the hosting company provides physical space that the server takes up and takes care of the server. This is the most powerful and expensive type of web hosting service. In most cases, the colocation provider may provide little to no support directly for their client's machine, providing only the electrical, Internet access, and storage facilities for the server. 
  • In most cases for colo, the client would have his own administrator visit the data center on site to do any hardware upgrades or changes. Formerly, many colocation providers would accept any system configuration for hosting, even ones housed in desktop-style minitower cases, but most hosts now require rack mount enclosures and standard system configurations.
  •  
  • Cloud hosting: is a new type of hosting platform that allows customers powerful, scalable and reliable hosting based on clustered load-balanced servers and utility billing. A cloud hosted website may be more reliable than alternatives since other computers in the cloud can compensate when a single piece of hardware goes down. Also, local power disruptions or even natural disasters are less problematic for cloud hosted sites, as cloud hosting is decentralized. 
  • Cloud hosting also allows providers to charge users only for resources consumed by the user, rather than a flat fee for the amount the user expects they will use, or a fixed cost upfront hardware investment. Alternatively, the lack of centralization may give users less control on where their data is located which could be a problem for users with data security or privacy concerns.
  •  
  • Clustered hosting: having multiple servers hosting the same content for better resource utilization. Clustered servers are a perfect solution for high-availability dedicated hosting, or creating a scalable web hosting solution. A cluster may separate web serving from database hosting capability. (Usually web hosts use clustered hosting for their shared hosting plans, as there are multiple benefits to the mass managing of clients).
  •  
  • Grid hosting: this form of distributed hosting is when a server cluster acts like a grid and is composed of multiple nodes.
  •  
  • Home server: usually a single machine placed in a private residence can be used to host one or more web sites from a usually consumer-grade broadband connection. These can be purpose-built machines or more commonly old PCs. Some ISPs actively attempt to block home servers by disallowing incoming requests to TCP port 80 of the user's connection and by refusing to provide static IP addresses. 
  • A common way to attain a reliable DNS host name is by creating an account with a dynamic DNS service. A dynamic DNS service will automatically change the IP address that a URL points to when the IP address changes.[2]

What is Bitcoin and How does Bitcoin work?


Bitcoin is a form of digital currency, created and held electronically. No one controls it. Bitcoins aren’t printed, like dollars or euros – they’re produced by people, and increasingly businesses, running computers all around the world, using software that solves mathematical problems.

Bitcoin is a type of digital asset, most commonly defined as a virtual, digital or crypto- currency.

Bitcoin was invented by Satoshi Nakamoto, who published the payment system in a whitepaper in 2008. Released as open-source software in 2009, the bitcoin system is peer-to-peer which means that transactions take place without the need for a third-party. These transactions or payments are then recorded in a public distributed ledger called the blockchain, which uses bitcoin as its unit of account.

The blockchain is the backbone of bitcoin, serving as a financial ledger without any trusted central authority - this means that it is decentralized and no single person or institution owns the currency.With every new transaction, recordings are added as 'blocks', which each block added in a linear, chronological order. Described in simple traditional banking terms - the blockchain is the full history of banking transactions, while the blocks are like individual bank statements. Bitcoins do not physically exist, instead there are only these records of transactions and balances.

The unit of currency in the bitcoin system is, simply, bitcoin. There are three symbols used to express bitcoin - BTC, XBT and ?. Bitcoins can be split down into alternative units such as millibitcoin (mBTC), microbitcoin (µBTC) and satoshi. Satoshi, named in honour of the bitcoin founder, is one hundred millionth of a bitcoin - the smallest amount possible.

You can acquire bitcoins as payment for a service or goods or through purchase at bitcoin exchanges.

Bitcoins, however, can be created by anyone - all you have to do is help process payments into the distributed ledger. By offering your own compute power to verify and record payments, bitcoins are created as a reward or payment for your services. This activity is widely known as bitcoin mining.

Bitcoin is an anonymous digital currency.Bitcoin is not real money. It's an online "currency"—virtual tokens that can be exchanged for goods and services at places that accept it, the same way you'd give someone a dollar for a cookie. But unlike a dollar, a Bitcoin has no serial number or any possible mechanism that could be used to trace it back to a buyer or seller. This makes it attractive to drug dealers and/or privacy advocates.

itcoin is a digital currency (also called crypto-currency) that is not backed by any country's central bank or government. Bitcoins can be traded for goods or services with vendors who accept Bitcoins as payment.

Bitcoin-to-Bitcoin transactions are made by digitally exchanging anonymous, heavily encrypted hash codes across a peer-to-peer (P2P) network. The P2P network monitors and verifies the transfer of Bitcoins 

The basics for a new user
As a new user, you can get started with Bitcoin without understanding the technical details. Once you have installed a Bitcoin wallet on your computer or mobile phone, it will generate your first Bitcoin address and you can create more whenever you need one. You can disclose your addresses to your friends so that they can pay you or vice versa. In fact, this is pretty similar to how email works, except that Bitcoin addresses should only be used once.

Balances - block chain
The block chain is a shared public ledger on which the entire Bitcoin network relies. All confirmed transactions are included in the block chain. This way, Bitcoin wallets can calculate their spendable balance and new transactions can be verified to be spending bitcoins that are actually owned by the spender. The integrity and the chronological order of the block chain are enforced with cryptography.

Transactions - private keys
A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain. Bitcoin wallets keep a secret piece of data called a private key or seed, which is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet. The signature also prevents the transaction from being altered by anybody once it has been issued. All transactions are broadcast between users and usually begin to be confirmed by the network in the following 10 minutes, through a process called mining.

Processing - mining
Mining is a distributed consensus system that is used to confirm waiting transactions by including them in the block chain. It enforces a chronological order in the block chain, protects the neutrality of the network, and allows different computers to agree on the state of the system. To be confirmed, transactions must be packed in a block that fits very strict cryptographic rules that will be verified by the network. These rules prevent previous blocks from being modified because doing so would invalidate all following blocks. Mining also creates the equivalent of a competitive lottery that prevents any individual from easily adding new blocks consecutively in the block chain. This way, no individuals can control what is included in the block chain or replace parts of the block chain to roll back their own spends.

Going down the rabbit hole
This is only a very short and concise summary of the system. If you want to get into the details, you can read the original paper that describes the system's design, read the developer documentation, and explore the Bitcoin wiki.

What is internet of things (IoT) ?

Definition - What does Internet of Things (IoT) mean?
The Internet of Things (IoT) is a computing concept that describes a future where everyday physical objects will be connected to the Internet and be able to identify themselves to other devices. The term is closely identified with RFID as the method of communication, although it also may include other sensor technologies, wireless technologies or QR codes.




The IoT is significant because an object that can represent itself digitally becomes something greater than the object by itself. No longer does the object relate just to you, but is now connected to surrounding objects and database data. When many objects act in unison, they are known as having "ambient intelligence."

The Future of IoT
As far as the reach of the Internet of Things, there are more than 12 billion devices that can currently connect to the Internet, and researchers at IDC estimate that by 2020 there will be 26 times more connected things than people.




According to Gartner, consumer applications will drive the number of connected things, while enterprise will account for most of the revenue. IoT adoption is growing, with manufacturing and utilities estimated to have the largest installed base of Things by 2020.

The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.

The Internet of Things (IoT) refers to the ever-growing network of physical objects that feature an IP address for internet connectivity, and the communication that occurs between these objects and other Internet-enabled devices and systems.

IoT Extends Internet Connectivity
The Internet of Things extends internet connectivity beyond traditional devices like desktop and laptop computers, smartphones and tablets to a diverse range of devices and everyday things that utilize embedded technology to communicate and interact with the external environment, all via the Internet.





  
Some popular IoT examples
Your car, for example, w1ill soon be able to drive itself around town. No steering wheel or pedals required! This is possible because of improved sensor technology and artificial intelligence that is capable of surveying the surrounding area, receiving accurate positioning via GPS, and making decisions faster than the human mind. The result is safer transportation that frees you up to accomplish more in a time that would otherwise be spent behind the wheel.



It includes wearable devices like your wristwatch can connect wirelessly to your phone via Bluetooth, enabling it to sync data to and from the Cloud. The number of steps you take during the day, your heart beat, and even your sleep quality can be monitored and stored in the cloud so you can access that information from anywhere.

What IoT means to the consumer
Thanks to IoT technologies, your home would be smarter. Your blinds could open and close with the sun, your air conditioning system could track the location of people inside the home to maximize efficiency by targeting cooling where it is actually needed. Your refrigerator could let you know when food is about to expire and add items to your shopping list automatically. These solutions all fall under the IoT umbrella, and this is really just the beginning.





For many homeowners, IoT technologies are already in place and work invisibly. Smart meters that measure electricity usage in a home have all but replaced traditional mechanical meters that would be ready by a technician once per month. These smart meters make it possible for you to log in to your electric company’s website and see exactly how much electricity you used on a given day, or even a specific hour.

A new industrial revolution
In an industrial application, IoT technologies power heavy machinery and provide critical information about the state and goings on of a complex production environment. IoT sensors can track a machine’s efficiency and activity and make way for improved automation processes. Huge amounts of data can be sent to a single control room where someone can monitor and control an entire production floor from a single point.



Security is another big area where IoT technologies can be put to good use. Home security systems are already becoming widely available with integrated apps and cloud-based monitoring so you can lock your doors and arm security systems from your phone rather than having to do so from a keypad in the home. You can do things like give someone access to the house temporarily from anywhere in the world.

To put it simply: The Internet of Things may be a buzzword, but it’s the best simple term we can use to describe the modern Internet. It describes an environment where your laptop, phone, and even your car are able to communicate with one another in order to make your life easier.
