Internet of Fewer Things

If you follow discussions about the Internet of Things, you’ve probably heard this stunning prediction at least once: The world will have 50 billion Internet-connected devices by 2020. Ericsson’s former CEO, Hans Vestburg, was among the first to toss out that number, when he gave a 2010 presentation to shareholders. The following year, Dave Evans, who worked for Cisco at the time, published the same prediction in a white paper.

Today, that figure has arguably done more than any other statistic to set sky-high expectations for potential IoT growth and profits. Remarkably, those projections weren’t even close to the highest at that time. A 2012 IBM forecast predicted 1 trillion connected devices by 2015. “The numbers were getting kind of crazy,” recalls Bill Morelli, director of the IHS Markit division that handles IoT and digital security.

Both Ericsson and Evans have since lowered their expectations for 2020: Evans, a cofounder of Stringify, who now serves as its chief technology officer, says he expects to see 30 billion connected devices by then; Ericsson figures on 28 billion by 2021. Other firms have adopted similar tones: IHS Markit projects 30.7 billion IoT devices for 2020; Gartner expects 20.8 billion by that time (excluding smartphones, tablets, and computers); and International Data Corp. anticipates 28.1 billion (again, not counting those devices).

That’s likely because it’s the third quarter of 2016, and we’re nowhere near 1 trillion IoT devices—or even 50 billion for that matter. The true total is somewhere between Gartner’s estimate of 6.4 billion (excluding smartphones, tablets, and computers), and IHS Markit’s estimate of 17.6 billion (with all such devices included).

But the popular 50 billion figure continues to be widely cited. Even Evans is a bit surprised by its staying power. “I think people do tend to latch onto numbers that seem really hard to fathom,” he says. “Fifty billion is pretty staggering.”

Peter Middleton, a research director at Gartner involved in the firm’s IoT forecasts, says such projections are intended to create “market efficiency,” by helping companies make smart choices about whether they should enter a new area and informing venture capitalists as they decide where to place their investments.

This is why the wild divergence in the numbers is problematic. But Vernon Turner, a senior IoT analyst at IDC, says it’s more practical—at least at this stage of a nascent market—to think of the estimates as a signal, rather than to focus on the specific numbers.

Bob Heile, standards director for the Wi-SUN Alliance and chair of the IEEE 802.15 WPAN effort (a working group for wireless personal area networks), says the general trend that early IoT analysts predicted has proven true. “What I do know, because the trend is absolutely undeniable, is more and more things are getting the ability to communicate and connect to something else,” says Heile.

But why isn’t there one plausible set of numbers? Two reasons: arithmetic and avarice. To begin their analyses, many firms collect annual sales data from manufacturers that produce connected devices or components such as semiconductors, as well as from companies that sell and ship those products to customers. Next, the firms subtract a percentage of devices to account for those that will be replaced or thrown out each year, and then they add estimates from past years. The result of this arithmetic is the “install base,” or approximate number of connected devices in use at a given time.

Some firms include other variables, such as industry growth rates or the amount of money that companies spend annually on information technology. And some conduct consumer and business surveys to gauge how devices are used, so they’ll know how many of the devices that are sold and shipped actually wind up connected to the Internet. Morelli at IHS Markit estimates that 90 percent of communications devices (including smartphones) are switched on, but perhaps only 50 percent of Internet-capable gadgets for cars are ever connected.

Janna Anderson, an expert in emerging technologies at Elon University, in North Carolina, says there is a degree of self-interest at play in projections, too. In 2013, she helped the Pew Internet Project survey more than 1,600 experts about what the IoT might look like in 2025. Not surprisingly, she found that “those who are marketing it and those whose bottom line is somehow impacted by enthusiastic predictions are more likely to make them.”

At this point, even the strictest definitions of IoT remain fuzzy because of breathless hype, including attempts to anticipate demand for devices that have yet to be invented or commercialized. But Stringify’s Evans, one of the original IoT optimists, is confident that entre­preneurs will find many millions of practical ways to serve customers through the IoT in due time. “I think technology needs to solve real problems, and if it doesn’t…[it] will die on the vine,” he says.

As the next 10 billion IoT devices come online, the industry will face some formidable challenges, such as ensuring the security of its devices, powering billions of sensors, and handling all the resulting e-waste. Despite those issues, Evans isn’t bashful about anticipating connected device ubiquity. “I could see trillions of connected things, ultimately,” he says.

Tips on ways increase internet connection speed

Computer geeks swear by the speed of the Broadband Internet Connection. But what happens when you are awaiting an important email and your connection is so slow that it makes you wait for an eternity before you can check your mail. Well, the first thing that one is going to do is curse the service providers! On a serious note, the next thing which could be done is to ensure that the speed increases. If you are not using a broadband connection, go for one. Using a DSL broadband connection will give you a fast access to the Internet.

Broadband Internet Access

Broadband Internet access, often called Broadband, is a high data rate internet access. It is also referred to as high speed Internet access because of the same reason. According to the Organization for Economic Cooperation and Development (OECD), broadband is defined as having a data transfer rate of 256 kbit/s or more. And this is the most common baseline, which is marketed or advertised as broadband all over the world. It does not interfere much with the telephone lines.

The Technology

DSL (Digital Subscriber Line) and cable modems are the standard broadband technologies. It is one of the technologies, which is used for Broadband. This technology facilitates digital data transmission over the wires of a local telephone network. Earlier, DSL was called Digital Subscriber Loop. But now, it is known as Digital Subscriber Line.

DSL is also the most widely used term for ADSL. ADSL is a very popular version of consumer-ready DSL. DSL can be used with a regular telephone, as it uses high frequency bands. The download speed of a DSL service for the consumer ranges from 256 kbit/s to 24,000 kbit/s. However, it depends on the line, technology, and service level conditions. Typically, download speed is faster than the upload speed as far as Asymmetric Digital Subscriber Line (ADSL) is concerned. In the case of Symmetric Digital Subscriber Line (SDSL), which is very rare, both the uploading and downloading speed is the same. The typical set-up involves linking the modem with the telephone line. DSL access is the easiest way for a high speed connection.

If you have tried using the DSL and you are not able to increase the speed, here are a few tips to increase your broadband speed.

– You can try deleting the Internet temporary files, browsing history, and the cookies.
– Check if the security settings are correct.
– Check out and manage the add-ons.
– Choose the advanced options as you want.
– Be sure that you have enough RAM (Random Access Memory).
– Try using broadband tweaks. The most common broadband tweaks are TCP receive window size, maximum transmission unit (MTU), maximum segment size (MSS), and time to live (TTL).
– These tweaks should be used only after the network is tested and is reliable.
– These tweaks, however, may enhance the performance of an online game, but may hamper the browser speed on the other hand.

The best way to avoid frustration arising from a snail-paced connection is to keep the computer memory free as much as possible, and updating the processor.

The security settings of the Internet Explorer browser can be found under the Tools menu of the browser, under the option Internet Options, under which you have to click on the Security tab. Check if the settings are same as they have always been. If not, correct them accordingly.

The tweaks can be applied to your computers using a Registry Editor, and changing the values on each.

Broadband Internet Connection

Broadband, unlike the dial-up Internet, offers high-speed Internet connectivity. Broadband Internet connection offers high rates of data transmission. Generally, broadband Internet users obtain Internet speeds of around 256 kilobits per second or more. Digital subscriber loop/line (DSL), cable modems, and fiber optics are some of commonly used broadband technologies. Let us look at each of them.

DSL: It refers to a series of technologies that are used to enable the transmission of digital data over local telephone wires. DSL Internet service offer speeds of 256 kilobits per second. Usually, it works by dividing the frequencies over a single telephone line into two bands; the high-frequency band for data and the low-frequency band for voice.

Cable Modem: A cable modem uses the cable network infrastructure to facilitate the transmission of data. It is used to provide the Internet users with broadband Internet access.

Fiber-optic Communication: It enables transmission of information in the form of electromagnetic waves over an optical fiber. Fiber-optic communication has enabled the transmission of data over large distances, thus facilitating broadband Internet access.

How is broadband Internet accessed? How can a broadband Internet connection be shared between two or more users? What are the advantages of sharing a broadband Internet connection? Here are the answers.

Broadband Internet Connection Access and Sharing

T1 is a T-carrier signaling system that facilitates the transmission of voice and data. It refers to a digitally multiplexed telecommunication carrier system developed by the Bell Labs. A T1 line can be plugged into a telephone system to carry voice and to a network router to carry data. Integrated Service Digital Network (ISDN) has traditionally been used for Internet access. A basic rate ISDN, also known as ISDN-BRI is an ISDN line with two bearer channels that can be used for broadband data transmission with the help of ISDN terminal adapters. Wired Ethernet is another method of broadband Internet access. As it offers very high speeds of Internet access, its bandwidth can be shared between users. For example, 100 Megabits/s Ethernet line can be shared between 10 users, each getting a speed of around 10 Megabits/s. Ethernet Internet access can be offered by means of fiber-optic or copper wires.

Microsoft Internet Connection Sharing (ICS) service is one of the methods used for sharing a broadband Internet connection. ICS is a feature offered by the Microsoft Windows operating system that facilitates the sharing of a single Internet connection. With the help of DHCP and network address translation (NAT), it routes TCP/IP packets from a LAN to the Internet and maps IP addresses of local computers to unused port numbers. Moreover, the IP addresses of the local computers are not visible on the Internet as the packets are exchanged through an external adapter on the ICS host. If two computers need to share a broadband connection, they can be connected by a crossover cable. In case, more than two computers need to share a broadband connection, they have to be connected by means of a switch or hub. One of the main advantages of ICS is that it is free and comes packaged with Windows XP and Windows 2000. Secondly, it is simple to set up and requires minimal hardware. However, ICS does not support certain applications like messenger and NetMeeting, and extends hardly any support for content logging and filtering.

A broadband Internet connection can be shared by means of a network router. With this method, the computers in a network are connected by means of a switch, which connects to a network router. The router functions as a network gateway and can be used by all the computers in the network to access the Internet. Similar to ICS, network routers also use the network address translation technology, whereby the IP addresses of network computers are not exposed to computers on the Internet. Network router is an excellent means of sharing a broadband connection as it offers a certain degree of network security. Moreover, routers are available at reasonable prices and are easy to set up in the network.

On lines similar to a broadband router, a network switch or hub can be used to interconnect computers over a network. It acts as a central point of connection or a gateway, through which the computers on a network can gain Internet access. To enable wireless devices to connect to the Internet, a router equipped with a wireless access point can be used. A computer with a network card in it can connect to a WAP, thereby allowing wireless devices to connect to the Internet.

What’s noteworthy about broadband connection sharing is that the computers collaborate to enjoy Internet connectivity. True, machines understand the joy of sharing. Ironically, some of us don’t.

Ways to Shop for Clothes Online

All of us have come across those beautiful dresses which are displayed in advertisements on websites on the Internet, haven’t we? The prices listed below the dresses not only amuse us, but also tempt us to buy them as soon as possible. These clothes are indeed one of the hottest selling items on the Internet, aren’t they? However, before temptation takes over, there are a few things you need to educate yourself with. There are a million websites all over the world that sell clothes online, so how do we choose the best? It’ll take us years to list all the websites that are considered authentic and diverse in their collection. The good news here is that you don’t need to look at so many websites. You can look at one website and judge it for its authenticity. Only and only if you think it’s not worth it, you can move on to finding another. The tips mentioned below will tell you how to shop for clothes online without risking your money and your expectations out of the bargain. Let’s check them out!

What to Keep in Mind While Shopping Online

Prerequisites
Buying clothes on the Internet has its prerequisites such as the knowledge of your physical statistics. You cannot possibly buy clothes off websites without knowing these. This is the basic information you should possess while shopping for clothes online. Again, it’s advisable for you to ask somebody else to take these measurements as that is how they are normally taken. If you take your measurements yourself, chances are they won’t be perfect as you would have to twist your body a few times to check the exact number of the tape.

Choosing
Choosing the right website should be your next task. Like I’ve mentioned before, there are so many websites that are involved in online shopping, it gets difficult to zero in on a few. Choose a website that has a record of selling a particularly good number of garments. Every website is going to show you beautifully clicked clothes but you also have to search for a website that provides you a lot of other information such as the name of the designer, the type of cloth used and more details regarding the styling.

Authenticity
Another great way in knowing how to shop for clothes online is by contacting the customer care center of that particular website you’re looking at. If the number is working and the customer support executives seem to be really well educated, you can bank on the authenticity of these websites to a larger extent. These executives will be able to guide you better than anyone else as the guidelines to be followed for shopping are different for different websites.

Additional Tools
A lot of people complain about the practicality of shopping on the Internet because according to them, these clothes can’t be touched, tried or even looked at in reality, as we do when we window shop! However, technology has advanced so much today that you can actually see how the dress of your choice looks virtually. There are websites that offer virtual model technology where you can customize the clothes you select according to your personal physical statistics. Some websites also allow you to customize the garments itself!

Suggestions
Ask/search for as many suggestions as possible so that you’re on a safer side before you actually start shopping. For example, choose websites that keep the identity and banking details of their customers hidden. Talk to people who shop for clothes on the Internet all the time or those who know people who do. Check enough reviews about the website you’re choosing. To reduce shipping costs and avail as many discounts as possible, order more items at one given time. Also, don’t forget to read the payment, return and grievances policy properly. If there are any conversions for currency, check those properly as well.

Now that know how to shop for clothes online, you can start looking at a few websites and implement these safe online shopping tips to keep your shopping secure. Try to check the authenticity of the websites you shop from, as many times as possible. Shopping on the Internet is slowly taking the idea of shopping to a completely different level. It’s always better to keep yourself updated with the latest trends in that case, isn’t it?
