What is machine learning? How it is helpful for decision making?
Technology truly has served as a catalyst in the process of development of our civilization. Human and machine co-exist today in a manner that they create a significant blend to connect and ease access issues. In this whirlpool of technology, AI (artificial intelligence) deserves a definite mention. It is based on a heavy algorithm. Machine Learning as an integral part of AI.Machine Learning implies a concept where the central belief that computers are capable of learning by themselves without programmed inputs to perform certain tasks. It is basically the process of empowering the computers. This can be broadly divided into ...
Read Morewhat is web hosting and how does it work?
Web HostingWeb Hosting is a service that allows companies and individuals to establish a website or web page onto the Internet. A web hosting service provider or a web host is a business that offers the technologies and services required for the website or webpage to be viewed whenever a user wants to view it through the Internet.How Does It Work?Special computers vastly known as servers store these websites and pages and help to access and view whenever they get the command. Their computers get connected to their server and your web pages will be delivered to their screen through ...
Read MoreWhat is LAN (Local Area Network) in Computer Network?
A local area network is a comparatively lesser and privately-owned network with the highest duration of 10km to support local connectivity within a building or limited geographical area.In private offices, this type of networking is trendy and effectively used. They are generally used to interface with personal computers and buildings, incorporate workplaces and industry to share resources and transfer data.The figure shows a LAN having computers from several departments like Sales, Finance, Production, Publication, etc.Features of LANLimited Geographic LimitsA LAN is constructed for a limited area. It usually traverses a single frequency workgroup floor in a building or on campus ...
Read MoreADSL versus Cable
ADSL −Asymmetric Digital Subscriber Line (ADSL) is a type of broadband communications technology to transmit digital data at a high bandwidth on existing phone lines to homes and businesses.Cable − Cable network is a system of providing varied services like television programming, FM programming, Internet and telephone services over existing cable TV network.Comparison of ADSL and Cable NetworksADSL uses the existing telephone lines for providing data, voice and multimedia services, while cable uses existing cable TV networks to provide similar services.Both ADSL and cable networks use fiber optic cables in their backbone. However, in the customer end, cable network uses ...
Read MoreLow-Earth Orbit Satellites
Low earth orbit (LEO) satellites systems orbit below 2000 km from the earth’s surface, i.e. below the lower Van Allen belt. They move at very high speeds and may not have any fixed space with respect to the earth.The following diagram depicts LEO satellites in their orbits.Features of LEO SatellitesA network of LEO satellites are needed for global coverage as their orbits are not geostationary.These satellites are not as powerful as the MEO and GEO satellites.Due to their high speeds, satellites move in and out of the earth station’s range from time to time. So, data is handed off from ...
Read MoreWhat are the differences between Physical and Logical Topology?
The network topology is a structure or the physical arrangement of the network devices, how the components of the network are interconnected with each other.Types of network topology are as followsBusStarRingMeshHybridLogical TopologyIt tells about a network that should be configured for the transfer of information. This is different from physical topology as it does not explain the physical wiring of a network, but instead, it describes the flow of data, information, and back, from one system to another and the routes it takes.Some examples of Logical topology are as follows −Logical Star Topology − Uses logical bus topology to transfer ...
Read MoreWhat is Campus Area Network (CAN)?
Campus Area Network (CAN) is also called a corporate area network and it helps to like LAN with small geographical space. The main objective is offering the best accessibility of campus residential regions like schools, colleges, university, small institutes (Campus), and corporate area (building). It is larger than LAN but small than WAN and MAN networksIt can cover many buildings in an area. Here all computers are connected together and have some relationship to each other.For example − Different buildings in a campus are connected using Campus Area Network (CAN) they help to interconnect departments, library and computer laboratories.Given below ...
Read MoreDifferentiate between Data Privacy and Data Security.
Let us understand the concepts of data security and data privacy.Data SecurityIt uses physical and logical strategies to protect information from cyber attacks, and accidental or intentional data loss.It is a technology and technique which is use to prevent the following −Unauthorized accessIntentional loss of sensitive dataAccidental loss or corruption of sensitive dataSo, data security is a technologically sophisticated, holistic approach which secures every network, application, device and data repository in an enterprise IT infrastructure.Data security includes the followingPhysical access controls to serversMulti-factor Authentication (MFA) requirementsLeast-privilege access controlsPassword complexity requirementsData encryptionIdentification and remediation of stale dataData PrivacyData privacy is defined ...
Read MoreWhat is ISCII Encoding?
The full form of ISCII is Indian Script Code for Information Interchange. It was established as Bureau of Indian Standards in 1991 and it is based on an earlier Indian Standard IS 10401:1982. It is a type of coding scheme for Indian languages.It is an 8-bit standard where lower 128 characters (0-127) conform to ASCII standard and higher 128 characters (128-255) are used to encode characters from an Indian script.ISCII encoding strategy is used in Unicode in their encoding. Generally the characters of the Indian language derive from the ancient Brahmi script. Mostly all the characters resemble closely to each ...
Read MoreWhat are the challenges of a Computer Network?
Let's try to understand what reliability challenges for computer networks are.This can be defined as packet loss, bandwidth saturation, and latency, but this type of information would be really unhelpful to those IT companies whose networks are small, and failures not well under- stood & might be limited to rebooting.Five reliability challengesThe reliability challenges for a computer network are as follows −Host IdentificationThe Host ID is the portion of an IP address that uniquely identifies a host on a given TCP/IP network.The smaller networks can be easily configured with the help of manual addressing, but it becomes a serious problem ...
