The world of data communication is busy, even noisy. Industrial communication systems, such as balanced RS-485 / RS-422, often require transmission between multiple devices over long distances. While having many devices communicating with each other on the same twisted-pair cable is robust and cost-effective, it also introduces two major challenges:
- Because of the long distances and the surrounding electrical devices/equipment, RS-485 / RS-422 networks are often exposed to electrical noises, remote lightning, and line surges, which can cause transient voltage to run across the serial communication system and the valuable equipment.
- Because multiple devices (nodes) are connected, the ground potential at different nodes could be different, which can cause ground currents to flow through “the path of least resistance” via either the common earth ground or the ground wire.
Both voltage and current surges can cause serious damage to valuable, mission-critical equipment such as computers, PLCs, and industrial manufacturing and data processing equipment; these surges can even endanger human lives. Ground loop problems also exist on unbalanced signals that rely on the ground pin being zero volts, such as RS-232 and USB.
The new era of computers has changed the way people communicate versus decades ago. The digital age has shifted from a traditional industry to an economy that is based on computerized information. The World Wide Web has existed since 1969, and is now globalized, accelerating the flow of information and pushing older forms of media into obsolescence. A computer is an electronic device used for storing and processing data. Almost, everything that is an electronic is made or run by computers. These devices have become a popular way to permanently accumulate collaborative information. Businesses have become dependent on this type of digital machine to store their files, complete daily task, and keep track of payroll. Practically, every home is equipped with some type of computerized mechanism. People are now using these types of electronic devices to share or exchange information, versus the traditional way when people had face to face conversations. The new era of computers has caused people to interact and facilitate relationships by using online dating, social media, and video conferencing.

Technology affects all aspects of our lives nowadays, from the work we do right through to the way we do it. So much has changed in recent decades that generations at school today are far more adept at using these technological features than preceding age groups, and this trend is set to continue.
In education today, IT education is not only about teaching students and pupils what they need to learn to advance in the modern world, but is also about how various tools and techniques can help them learn more efficiently. Here are some of the main reasons why IT education solutions are so important.
Firstly, it is important to put in place an IT solution for schools as it can help students get the most out of learning. With many classes today utilising various devices and technologies to learn, ensuring that these are being used in the most efficient way possible to maximise the learning experience is very important.
Devices such as smart boards and tablets all have their role in the classroom, but being set
The latest telematics market trends continue to point towards providing in-car connectivity and by 2016 2G network connectivity will be a thing of the past. Therefore, it goes without saying that there’s a huge market potential that still remains untapped as far as the telematics ecosystem is concerned.
In the recent past, we have seen that providing connected cars has taken a new momentum and every car maker is gearing up to facilitate connectivity that offers powerful network technologies even as faster networks like 3G and 4G are emerging. For example technologies supporting real-time driver safety instruction, fleet maintenance programs, including fuel and productivity tools are now available worldwide for vehicle users to peruse – all this at the same price points as previous years’ tech.
According to Ernst & Young, by the year 2025 the market penetration statistics is expected to be 88% for new cars. This is a new paradigm shift as far as in-car connectivity of integrated telematics is concerned. In the US alone, by 2025, 16 million new cars are going to be equipped with embedded telematics. Let’s quickly take a look
Have you ever wondered just how the touch screen on your cell phone, tablet, LED television, or any other device actually works? It is amazing to think that we can now issue commands to our devices with the touch of our hand and while this technology might seem new, it has actually been around since the 1960’s.
In fact, the technology behind the touch screen can actually traced right back to the 1940’s but it was only two decades later that it actually became feasible to use on a large scale.
ATMs have been using technology since 1965 which is when E.A. Johnson invented the first finger-driven touch screen that actually used the same capacitive touch mechanism that is still used in cell phones and other devices to this day.
Although there are other types of touch screen technology such as resistive touch or multi touch technology, capacitive touch technology is the one that is preferred for mass produced consumer products.
How is a Capacitive Touch Screen Made?
Today, a capacitive touch screen works through the use of an ITO touch
For many businesses moving over to cloud computing options, the process can be daunting and present many potential hiccups. Regardless of this, there are many benefits to these new solutions that have meant that companies are making the leap anyway, reaping numerous rewards such as improved efficiency and greater collaboration in the workplace.
With that said, often a great level of support is required when initially migrating to these services and in the first phases of getting to grips with them. Furthermore, ongoing support can be considered extremely valuable in many instances.
One of the most popular cloud tools available today is Microsoft Office 365, which is a cloud based application including a variety of Office tools. This has numerous advantages, including the familiar Office applications in a more collaborative and accessible package that also feature frequent updates and improvements without the need to purchase an entirely new package.
Again, moving over to this collection of cloud tools can be stressful and difficult for some businesses, and investing in a support service can have untold benefits.
Your network is only as effective as its reach – yet unbalanced signals such as USB and RS-232 can reliably transmit only up to 15 feet, and even balanced Ethernet signals are capped at 300 feet. With a growing range of connectivity platforms, modern data networks require not just compatibility and reliability but also flexibility and expandability. There are many ideal solutions to meet modern networks’ data distance needs such as converting unbalanced signals to balanced ones, deploying repeaters to boost signal strength, and implementing hubs for star-configured connections, while still taking full advantage of cost-effective and readily available copper wire. For large systems that go far beyond what copper wires can reach, fibre-optic converters can used to work in both conventional point-to-point and advanced daisy-chain / redundant-ring configurations, giving your data network a boost in distance, ranging from 3 miles to hundreds of miles, and additional flexibility, reliability, and expandability. The use of a Serial-TCP program is another ideal solution for merging serial communication protocols with modern TCP/IP communication, yielding benefits such as widely available infrastructures and greater distance, reliability, and speed.
Point to Point
The Bose SoundSport Wirelesst is essentially an “open” ear-bud style headphone that effectively isolates noise. It is an in-ear headphone designed for those who don’t wish to get their eartips jammed way into their ears. Thus the buds remain loosely in your ears, held in place by means of proprietary StayHear tips that are is made in a particular shape, in order to act as a soft seal at the opening of your canal, thereby helping to improve audio performance. Plus, there is a flexible wing that makes use of the ridge of the ear for active support, thereby imparting appreciably improved stability without the need to force the tips in.
Design and Features
StayHear tips work well your ears, keeping the buds securely and comfortably locked in, even while you are jogging. However, the open design can let in ambient sounds, so they aren’t much good when you are in a noisy environment. The Bose SoundSport Wirelesst comes with a unique sport version of the Stay-Hear tips that conforms to any ear shape, and remain in place comfortably, throughout the day. They are available in
The Payment Card Industry Data Security Standards (PCI DSS) requires the merchants dealing with credit card holder data to perform regular vulnerability scans, in order to keep their security flaws covered. Merchants often come with a question, “When do you need to run a PCI Scan?” the answer to this question is quite simple.
What are the Requirements of the PCI DSS for Vulnerability Scans?
In order to know when the PCI Scan is required, we should know about the PCI DSS requirements first. The PCI DSS requires merchants to run both “Internal and External” vulnerability scans, in order to keep the credit card holder information system up to current security standards.
External Scans: External scans should be conducted from the outside of the organization and must include all the external IP addresses. These scans will help you to know about vulnerabilities in your security system that might be breached by the hackers to get hold of the sensitive credit card holder data.
Internal Scans: Internal scans must be performed from inside the organization’s network from multiple locations to know about the security
The term PCI stands for Payment Card Industry, and we all are quite familiar with the different types of credit card / payment solution companies available, like Master Card, PayPal, and Visa etc. This article will further discuss how these companies manage their security of card holders’ data.
These companies run under the standards of PCI DSS, which stands for Payment Card Industry Data Security Standard. According to these standards, the information of card holders are to be kept secured.
History of PCI DSS
There are Five programs:
1. American Express’ Data Security Operating Policy
2. Discover’s Information Security and Compliance
3. JCB’s Data Security Program
4. Master Card’s Site Data Protection
5. Visa’s Card holder Information Security Program
They were initiated by these credit card companies.The intention of each company was nearly the same; and that was, to develop an additional layer of protection for card holders and card issuers, by making sure that merchants meet the minimum levels of security when processing, storing and transmitting credit card data.
These same ideas led to the formation of the Payment Card Industry
Lately, artificial intelligence has been very much the hot topic in Silicon Valley and the broader tech scene. To those of us involved in that scene it feels like an incredible momentum is building around the topic, with all kinds of companies building A.I. into the core of their business. There has also been a rise in A.I.-related university courses which is seeing a wave of extremely bright new talent rolling into the employment market. But this is not a simple case of confirmation bias – interest in the topic has been on the rise since mid-2014.
The noise around the subject is only going to increase, and for the layman it is all very confusing. Depending on what you read, it’s easy to believe that we’re headed for an apocalyptic Skynet-style obliteration at the hands of cold, calculating supercomputers, or that we’re all going to live forever as purely digital entities in some kind of cloud-based artificial world. In other words, either The Terminator or The Matrix are imminently about to become disturbingly prophetic.
Should we be worried or excited? And what does
Since the formation of Payment Card Industry Data Security Standards back in 2004, PCI DSS has setup its requirement for financial service providers and large merchants to use QSAs to carry out onsite assessments and to check on Compliance and security. QSA stands for Qualified Security Assessors; it is a designation awarded to individuals by the PCI Security Standards Council, whom it finds qualifying to execute consulting services and PCI assessments.
Recently, PCI DSS has expanded to take in its guidelines for training QSAs and some other advancement. Still QSAs and the services they provide do vary a lot. With assessors, the thoroughness, methodologies, technical skills and some other areas differ a lot.
The PCI DSS V2.0
The PCI DSS v2.0 released on 30th October includes number of classifications and further areas of guidance for assessments. The standard according to new version states that the first step of any PCI DSS assess is to describe the scope of assessment, by pointing out clear maps (locations and flows) of cardholder information within a system.
A lot of organizations are not aware about every single location where the
No matter who you are or where you are, you are likely feeling the growth of touchscreen technology. Today, regular flyers typically go into check ins and flight info using self-serve stands and soar through airport check-in, skipping the otherwise long lines. Busy drivers may use automobile touchscreen systems to find instructions, control air temperature level and more. And business people who require interaction access at all times invest in sophisticated communication devices to stay in touch.
Whether it’s utilized by people visiting the ATM to get some quick money or casting a vote, touchscreen innovation is taking off, transforming everyday tasks into quick and convenient experiences.
The innovation appeals to all ages and in a variety of markets. Retail outlet store merchandisers are using touchscreen as a brand-new marketing technique to engage consumers while providing item info at the touch of a finger.
FOA Schwarz, for example, has actually installed 17-inch Planar touchscreens as part of a customer design center for the Custom Car Factory in its New York store. Using the Planar touchscreen stand, buyers can customize their own
Gone are the days when companies used traditional flash to handle workload. There are several drawbacks of this conventional storage – you can use one flash for a specific type of workload; you can get the fast performance by spending several bucks, and several others. Tegile is the company of a new breed of innovators which brought its products to reduce the dependency of enterprises on heavy and expensive systems. Its products (hybrid and all flash) are enough to handle any type of workload.
From small-scale industries to well-established organizations are using its system. The company introduced its eccentric products keeping the users’ demand in mind for both All-Flash and Hybrid. All of its solutions are based on two types of architecture. Intelligent Flash Arrays for Hybrid & All-Flash, and IntelliStack Converged Infrastructure solutions.
The IntelliStack is developed by integrating the computing power of Cisco UCS and storage feature of Tegile. And thus, you can provide the configurations which are certified, pre-validates and pre-sized. If you are looking for a system, which can work best for your latency-sensitive, business-critical applications, then you should opt for the all-flash
Want to eliminate platform migration headaches? Reduce cost, effort, and lost time? You’re in the right place. I want to share some tips to help you simplify your migration activities.
I have been performing file-based migrations for well over 20 years, primarily with EMC Technology. The majority of migrations have been SMB-based including server-to-server, server-to-NAS, and NAS-to-NAS migrations.
Some of the tools that I have leveraged over the years include:
- ROBOCOPY: This Microsoft utility, originally part of the Windows NT 4.0 Resource Kit, has been around since 1997.
- EMCOPY: This EMC utility is used primarily to copy to a Celerra based file system; however, the other tools in the suite comprised of EMCopy, Sharedup, and LGDUP have been used on several occasions, even in conjunction with Robocopy.
- RSYNC: This UNIX utility is used for NFS migrations.
As technology advanced, storage vendors provided a way to perform these migrations using internal tools. Some of the tools were developed for disaster recovery while others were developed explicitly for data migration. Two examples include:
- VNX Replicator: This tool can replicate from Celerra/VNX to another Celerra/VNX array.
- Isi_vol_copy: The
Cloud computing has revolutionized the way technology is used to share information and resources to achieve coherence, relevance and economy of scale. These three factors are hugely important today when individuals and businesses require being in the forefront of their activities and achieving profits and revenues while reigning in expenditure.
This kind of computing is the method or model of internet-based computing that provides on demand, processing capabilities as well as data to computers and other devices on a network through a shared pool of resources such as applications and services, networks, servers and storage devices, which can be requested and used with minimal effort. Cloud computing enables businesses and users with capabilities to store and process vital data in third-party data centers.
In simple terms, cloud computing means the storing and accessing of information and applications over the internet instead of leaving them on local hard drives or in-house servers. The information accessed is not ‘physically close’ and the metaphor ‘cloud’ relates back to the days of flowcharts, graphs and presentations where the server infrastructure was depicted as
Recycling of old computers and electronic gadgets is not only a matter of accruing profit, but also a clever stride to take, towards the creation of a cleaner world; free of e-wastes. The correct method of e-waste disposal task makes the entire difference.
Technologies and electronic gadgets become obsolete within no time and get vanished away from the market outpacing the speed of their emergence into our lives. The first generation of computers, for instance, provides a perfect example of such discovery of mankind that have gone through the ups and downs of ages to become one the most powerful electronic human-friendly device, the sixth generation of computers; a completely new version of computers that have accelerated the society to reach new heights. But the days are not so far when this wild progression, will cause this smart machine not to perform, but sit idle on the pages of history.
Here the most important question arises regarding about what needs to be done with these time-worn machines and computers. They cannot serve as alluring show-pieces neither can be stacked up to consume spaces inside the
The advancement of new technology has been taking place since the beginning of human history. From the invention of items like the spear and knives made out of rocks and sticks to aid in the capturing and killing of animals for food, to items like the first printing press and the computer. The question: are the impacts positive or negative?
Technology is a word used to collectively describe or portray the advancements, abilities,creations, undertakings, views, and knowledge of a singular group of persons: we as human-kind. The advancement in technology has been exceptionally fast in the 20th and 21st century. With electronic technology and machines being produced and improved all the time, it was very likely that along with the positive aspects of these new advancements, people would also consider the negative aspects and look to criticize new technology.
A Positive Side
As the old age states “NECESSITY IS THE MOTHER OF INVENTION” i.e. necessities tend to spawn inventions and each invention is annexed with the need of betterment and transmogrification. Newer and newer advances are happening by the day.
Not many companies are well versed with camera designs and their tweaks and hence few players are moving towards custom development of board cameras and smart vision sensors based on different processors. Also with the advent of several cameras and camera architectures, companies now have a strong base to build new products.
Some companies can design cameras to customer requirements in short timelines too.
Companies usually face the challenge of meeting hardware and software design specifications of the camera.
High definition images might have to be clicked at regular intervals, sometimes in a fraction of a second! Some companies now opt for drones that would house several cameras, and then try to stitch and synchronise the images simultaneously, so that the shots can be taken from all possible angles.
Also the core challenge here is to reduce the camera size since the product needs to be a marketable product that also needs to be considerably affordable.
For such a camera design, companies strike a balance with its hardware design, PCB design, Bootloader porting, and the efforts expended on Device
Learning has seen a major transition in the last decade. For years, students have been using only textbooks for their study, which actually made the entire learning system boring. Today, printed textbooks have been replaced by digital learning software. Students are now using laptops, tablets and other learning tools instead of textbooks. While students are embracing technology, which has made learning more fun for them, and parents are happy that their children are finding learning interesting, and thus performing better in their academics, digital learning has become quite popular among teachers as well. Today, we see that schools and colleges are introducing eLearning as one of their core forms of learning methodology.
Digital learning has several benefits, which are highly unlikely to be found in a typical age-old classroom setting. This is only because, it is powered by technology, thus offering attractive benefits.
Personalized learning method: Digital learning can be easily customized by teachers, according to a class’s need and even every student’s need. Based on the student’s strong and weak areas, the learning method adopted for each student can be different, suiting their requirement and goals.
