What is Ethernet?

-
    Ethernet is a certain type of a local area network (LAN) which was developed in 1972 in the renowned PARC-research facility of Xerox in Palo Alto by Robert Metcalfe. Ethernet is a standard communications protocol used to connect devices including computers, routers, and switches in a wired or wireless network.As a data-link layer protocol in the TCP/IP stack, Ethernet describes how network devices can format and transmit data packets so other devices on the same local or campus area network segment can recognize , receive and process them. 


     Ethernet was originally standardized as IEEE 802.3 with a data transmission rate of 10 Mb/s. Newer versions of Ethernet were introduced lately to offer higher data rates. In today's Gigabit Ethernet supports speeds of up to 1,000 Mbps. Though it's currently limited to businesses on the cutting edge of the tech world, 10 Gigabit Ethernet with speeds of up to 10,000 Mbps is also on the way. The basic terminologies used in the Ethernet are Node ,Medium, Segment and Frame. The nodes are the devices like computers,routers, and peripheral devices that communicate through Ethernet. The medium is the path used by the devices to communicate. In Ethernet, the medium can be a coaxial cable, twisted pair cable , or it can be a fiber optics cable. The segment is the shared medium that is being shared by the network devices. The frame is the short message shared over the network. 

    

     The CSMA/CD is the most widely used Ethernet protocol. The purpose of this protocol is to handle the discarded, lost, or corrupted packets. In Ethernet the network devices wait for the free path to transmit the messages (frames) over the network. If two devices transmit the messages at the same time, a collision occurs and the messages (frames) are discarded. The CSMA/CD protocol is used to prevent the data loss from such collisions. Also Ethernet devices are backward compatible.There are few limitations of Ethernet. Since the Ethernet operates on a shared cable, the length of the cable matters a lot in the performance of the network. If the cable length is long, the signals may drop and the network performance may not be up to the mark. Similarly, the Ethernet devices wait for their turn to transmit the signals. This not only cause delay in communication but also cause the data loss due to the collision of the signals.Ultimately, the choice to switch to Ethernet boils down to your needs, preferences, and budget. Most homes that use the Internet for HD streaming, and smartphone  will be a-OK with a dual-band Wi-Fi router. But if you're trying to maintain your spot on the leaderboard of your online game or you run a business where online stability and profit go hand-in-hand you will need Ethernet.

What is Fringe Science?

     Fringe science is a branch of science that departs from the mounted clinical theories. Unlike pseudo-science , it nevertheless makes use of the clinical method, however is notably speculative. Fringe science has its foundation in mounted science , however explores and research regions on the very boundaries, and is frequently poorly funded and under-resourced. Whilst fringe science commonly leads upon a street to nowhere, once in a while a department blossoms into a totally established field, and can even result in a   paradigm shift . Chaos concept operated on the edge of well-known physics, the use of computer systems and era begged, borrowed or stolen from different departments. The younger scientists who labored upon it had been instructed that they could have problem locating funding, that different physicists could refuse to study their work, and they could by no means flow upwards. Fortunately, they persisted and arrived at a concept, that's extensively well-known

What is Quantum Computing?

T he field of quantum computing was initiated by the work of  Paul Benioff  and  Yuri Manin  in 1980,  Richard Feynman  in 1982, and  David Deutsch  in 1985.The typical computer uses a series of zeros and ones to communicate information. While today's computers are quite powerful, they still have considerable limitations that make it difficult to process challenging machine-learning problems. In quantum computing, a qubit (short for quantum bit) is a unit of quantum information—similar to a classical bit. Where classical bits hold a single binary value such as a 0 or 1, a qubit can hold both values at the same time in what's known as a superposition state. When multiple qubits act coherently, they can process multiple options simultaneously. This allows them to process information in a fraction of the time it would take even the fastest nonquantum systems.   We can ready for the quantum era by becoming a quantum developer. By learning a quantum-focused programming

Cyber Security

   What is Cyber-Security? Cyber security or information technology security are the techniques of protecting computers, networks, programs and data from unauthorized access or attacks. A successful cyber security approach has multiple layers of protection spread across the computers, networks, programs, or data that one intends to keep safe. In an organization, the people, processes, and technology must all complement one another to create an effective defense from cyber attacks. Elements of Cyber-Security Ensuring cybersecurity requires the coordination of efforts throughout an information system, which includes: Network security includes activities to protect the usability, reliability, integrity and safety of the network. Effective network security targets a variety of threats and stops them from entering or spreading on the network. Application security  focuses on keeping software and devices free of threats. A compromised application could provide a
