Power over Ethernet (PoE) is a network feature defined by the IEEE 802.3af and 802.3at standards. PoE switch is used to power networked devices with Ethernet cables via the existing data connection.
PoE-compatible devices can be used as Power SOURCES (PSE = Power Sourcing Equipment), Powered Devices (PD = Powered Device), or sometimes both.
The device supplying power is a PSE, while the device that is powered like the Techage 8CH 1080p CCTV Security System is PD equipment.
Most PES are network switches or PoE injectors for use with PoE-free switches. Some common examples of PD (Powered Device): VoIP phones, Wi-Fi access points,...
Technology advancement is a topic that cannot be exhaustively discussed because when we think a man has gotten to an unbelievable and remarkable height, the standard gets broken again without something more sophisticated. We would love to look a little into the future and predict what man will do with the likes of Artificial Intelligence, Blockchain and more.
These are the views of some experts in the line of technology
I want to mention two technologies that are slowly revolutionizing how most tech companies and tech platform work today.
Applied Natural Language Processing
For decades, NLP was a computer science field that had...
Technology has change the way we acquire education degrees. According to our research and online interviews, experts believe that many employers pay more attention to skills without college degrees than those with college degrees but this is most likely applicable to those in the technology field.
Here are what experts think about the effects of digital learning in education and employment system.
Our research with 200 manufacturing employers showed that companies are less interested in degrees than with skills. IBM says that a full 1/3 of manufacturing jobs in their US Plants don’t require a college degree.
New programs like Digital Badges...
We don't want to believe in speculations that's why we interviewed crypto experts to tell us what they think will happen to cryptocurrency in 2019. As we know the crypto price in this past 10 months hasn't been all good.
Here are experts analysis of what will happen to cryptocurrency in 2019:
Mobile wallet usage will increase as smartphone purchases continue to rise. This will open the potential for fully compatible crypto and credit card mobile wallet to be introduced by the end of the year. Imagine one wallet on your mobile device that stores your cryptocurrency and traditional currency....
The concept of blockchain technology is a recent one but has gained a lot of importance these days due to its wide applications in a plethora of fields. The term blockchain, as the name suggests, is made of various blocks, indicating a list of records and chain refers to the way in which these blocks have been linked using cryptography.
Every block contains information about the previous block, forming a link or chain.
The biggest advantage in case of blockchain technology is that the information cannot be altered. The blockchain is handled by peer-to-peer network adhering to a particular protocol.
Thus, once...

A cryptocurrency is a digital or virtual currency that is designed to work as a medium of exchange. It makes use of computer cryptography to secure and confirm transactions as well as to have control over the distribution of new units of that particular cryptocurrency.
Essentially, these digital currencies are limited entries within a database that no one can change unless they fulfill a set of very specific conditions.
Cryptocurrencies have become very popular investments recently, as they start to gain mainstream acceptance by major banks and financial institutions. Several online brokers let you get in on the action by offering...
The blockchain is a transparent and distributed ledger that uses various forms of cryptography to digitally sign blocks of data to ensure the integrity of the data and remove third-party intermediary.
Today, we will focus on the two main technologies in a typical blockchain implementation; distributed ledger and cryptography. The different implementation might add to this but this is the basic technology stack for blockchain.
Distributed Ledger
A distributed ledger database is really the core value of a blockchain technology implementation. It is basically storing a series of transactions in a way where the hash or cryptographical signature or the previous transaction is used to encrypt the next...

What is Blockchain?
Blockchain technology operates as a common, cryptographically verified ledger, distributed across a broad decentralized network of computers (or nodes), largely known for its use in recording value transactions and exchanges.
Each ledger entry is considered a “block” in the broader “chain,” and each block is cryptographically validated by a consensus-based algorithm which is computed across the node network.
Each block is not added to the chain...
Blockchain is basically a ledger; a distributed one. All transactions that occurred on that particular Blockchain are recorded and then stored on the ledger in a form of block data. Once the ledger successfully stores a transaction, it can be removed. This means that with each transaction, the longer the chain of data blocks become.
One of the implications of this is that the complete history of transactions from the recent ones to the first entry is available for verification always. A complex cryptography protects all the data recorded in the distributed ledger and when you possess the key, you...
