   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 c...

     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 10,00...

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 develop...

1.Moon Plains   Moon Plains ( also known as Sandatanne, Sandagalatanne) is the latest attraction open to public in Nuwara Eliya. T his was once the dump site of the tons of garbage used by the dwellers of the nearby city. It was cleaned and reconditioned in 2010, and is now classified as an Agricultural and Environmental Tourism Zone by the Municipality of Nuwara   Eliya .  The plains is located few kilometers off Nuwara Eliya town and is accessed passing the the Government Potato seed Farm at Sita Eliya. The main attraction of Moon Plains is the mini Worlds End at the edge giving a 360 Degree view of the surrounding peaks and towns. The plains is home to Elk, wild buffaloes, dear and many types of birds. This area is also  visited by leopards. Direction -   https://goo.gl/maps/1TNy9anQo1w
