The Downside of Big Data

February 8, 2018 at 8:00 AM

 

Big Data is all the rage right now and is the driving force behind a lot of new technologies breaking barriers today, including data science, artificial intelligence and the Internet of Things (IoT). Even though big data may help us to achieve medical breakthroughs, explore far away galaxies, plan and prepare for natural disasters and even feed the hungry, there are still some downfalls. Along with the insights and opportunities that come with all this data being collected, there are some significant issues that need to be recognized.

 

The first issue is privacy. The big data being collected contains a good deal of personal, private information about our lives and we are entitled to keep that information private. With so many apps and services being offered that use big data, it is becoming increasingly difficult to determine who should be able to access to our data and how much we should divulge. Finding a balance between accessing the benefits of big data while still maintaining some type of anonymity is an issue worth discussing.

 

Secondly, data security concerns are growing as fast as the big data industry. The high-profile data breaches last year brought to light how important it is to secure our data. Can we truly trust anyone to keep our data safe? If a trusted source is breached, sensitive information ending up in the wrong hands can deeply impact our lives for years to come. Plus, is the legal system equipped to regulate data use at this large scale and if our data is compromised, can appropriate legal action be taken?

 

 

One more area of concern is data discrimination. With all this data available, how will it be used, and will people be discriminated against based on the data collected? For example, credit scores are used to determine who can get a loan and we’ve seen that those can be compromised, which can have devastating effects on people’s lives. The insurance industry also relies heavily on data to determine coverage and rates, meaning people could be charged more or denied coverage based on these reports. Increased detail in the data collected will also increase scrutiny from companies. Steps might need to be taken to ensure that resources or opportunities aren’t taken away from those who have fewer options and less access to information.

 

Overall, big data is making a lot of big advances in the technology industry. Care might need to be taken that this data is used in the proper way, that private matters are kept private, that people’s data is secure and that regulations are in place.

411 on HDMI 2.1

January 18, 2018 at 8:00 AM

 

HDMI is one of the most widely recognized technologies used in video display applications today. It is used on newer HDTVs, Blu-ray players, Apple TVs, computers and many other video display devices. Able to stream both video and audio at the same time, the simple plug and play interface is easy to use, offers high definition video, crystal clear auido, and now HDMI is about to get even better!

 

HDMI recently released its newest specification, HDMI 2.1, and it is slated to take video to the next level.

 

Here is the 411 on HDMI 2.1:

 

·       Supports a range of higher video resolutions and faster refresh rates, including 8K 60Hz and 4K 120Hz for a captivating viewing expereince and smooth fast-action detail

 

·       Dynamic HDR displays every monent of a video at its ideal level of depth, detail, brightness, contrast and wider color gamuts, even when being viewed frame-by frame

 

·       48G cable for increased bandwidth up to 48Gbps for uncompressed HDMI 2.1 to support features including HDR and 8K video

 

·       Backward compatible with earlier HDMI versions

 

·       eARC provides support for advanced audio formats such as object-based audio. It also allows for advanced audio signal control abilities including device auto-detect.

 

·       Game Mode VRR includes variable refresh rate, which permits a 3D graphics processor to display the image at the same time it is rendered. This provides gameplay with better detail and more fluidity, it also reduces or eliminates lag, stutter and frame tearing.

 

As with all HDMI desginated products, thorough testing must be done to garner the HDMI 2.1 seal of approval. In regards to earlier HDMI specifications, HDMI 2.1 will superceded 2.0b and will continue to refernce and rely upon the 1.4b specification. HDMI 2.0 adopters will automatically have access to the HDMI 2.1 specification, HDMI 1.4b adopters will not have access. HDMI 1.4b products will continue to be tested to the 1.4b requirements. HDMI 2.1 compliance test specifications were published last year. The timeline for beginning compliance testing for HDMI 2.1 will be decided by each individual authorized testing center.

Our Best-Selling Product of 2017

January 4, 2018 at 8:00 AM

 

To start off this year, we would like to take a moment to present the award for the best-selling product of 2017.  With so many high-performing, quality products in the running, the competition was fierce. But after all the votes (sales) were tallied, there was one clear winner.

 

And the winner is……(drumroll).…. the ECF504-SC5E coupler!

 

If you’re not familiar with this year’s best-selling product, here is what you’ve been missing:

 

The ECF504-SC5E is a Cat5e, RJ45, shielded, 8x8, panel-mount-style coupler that is ideal for telecom, LAN, voice/data and IDF/MDF applications. It is a part of L-com's ECF panel-mount RJ45 coupler line that combines an innovative design with a competitive price. With a solid, die-cast, metal mounting frame, these unique RJ45 couplers allow panel mounting with virtually any panel thickness.

 

This unique coupler is very versatile and was used in a wide variety of applications and purchased by a varied group of customers including OEM’s who used the ECF504-SC5E in enclosure and panel products, IT professionals and network installers who used the ECF504-SC5E in data center applications, and a host of other customers who used the ECF504-SC5E in a variety of Ethernet cable pass through applications.

 

On behalf of the ECF504-SC5E, we would like to thank all the customers who helped this product win the 2017 best seller award. Without your support, and purchases, none of this would be possible. (cue music).

 

Readers’ Choice -Top Blog Posts of 2017

As we wrap up another year, we’d like to take a moment to look back on some of our most popular posts. We pride ourselves on providing informative content for our readers by covering a range of wired and wireless technology topics. We sincerely hope that you enjoyed reading our posts as much as we enjoyed writing them and in case you missed anything, here’s a highlight reel of the most popular posts of 2017.

 

 1.       Cable Showdown: Cat6 vs. Cat6a

 

It’s a Cat eat Cat world out there and Cat6 and Cat6a are two of the most popular standards for Ethernet cables. So, how do you decide between the two? One may work better than the other, depending on your application. To help you pick a winner, we compared them side-by-side for a showdown of category proportions. To see how each Cat fared, read the post.

 

 

2.       White-Space Wi-Fi 802.11af

 

Waste not, want not, seems to be a growing way of life for many people these days, and that theme will soon apply to the Wi-Fi spectrum as well. The IEEE standard 802.11af, also known as white-space Wi-Fi or White-Fi, will utilize the unused space in the TV spectrum, the TV white-space, to support Wi-Fi networks. Read the post to find out how it all works.

 

 

3.       OM5 – The Next Generation of Multimode Fiber

 

OM5 was chosen to be the new standard for cabling containing wideband multimode fiber in the 3rd edition of the ISO/IEC 11801 standard. The acceptance of this standard is a milestone for the fiber cabling performance category because it extends the benefits of this revolutionary multimode fiber within connected buildings and data centers worldwide.

4.       802.11ax – The Next Big Thing

 

The IEEE will be adding to its 802.11 series of standards again with the launch of 802.11ax. 802.11ax is under development and will pick-up where 802.11ac left off by taking MIMO to the next level with MIMO-OFDM. This next big upgrade to Wi-Fi networks might not make its debut for a couple of years, but here’s a look at what’s coming.

 

 

5.       75 Ohm vs. 50 Ohm – Coaxial Comparison

 

Ohm may sound like something you’d say while meditating, but when it comes to coaxial cables, it is actually a unit of resistance. Ohms measure the impedance within the cable. Impedance is resistance to the flow of electrical current through a circuit. To see how 75 Ohm and 50 Ohm compare, read our post.
