Migrant Workers (प्रवासी-मजदूर): Getaway From City in 2020

प्रिय साथियों (Migrant Workers),

कुछ दिनों से प्रवासी मजदूरों (Migrant Workers) का पलायन चल रहा है अपने गांवों की तरफ इस बारे में मैं कुछ अपने विचार आपके सामने व्यक्त करना चाहता हूं | मैंने अभी तक यहीं पढ़ा एवं सीखा है की हम हर इंसान में भगवान देखें एवं उनकी मदद करें |
यह मजदूर वर्ग (Migrant Workers) जो कि पलायन कर रहा है अपने गांव की तरफ यह वही वर्ग है जिसने की देश में बड़े-बड़े निर्माण अपने घर से दूर रहकर के करें हैं |

संकट की इस घड़ी में जबकि हर तरह से इनका धंधा भी बंद हो गया है तब यह अपने प्रिय जनों के पास जाने का प्रयास कर रहे हैं |

migrant workers

मैं किसी भी हालत में सरकार या विपक्ष के बारे में कोई भी टिप्पणी ना तो करना चाहता ना कर रहा हूं | लेकिन एक बात मैं तहे दिल से जरूर कहना चाहूंगा की इन मजदूरों की जो भी जितनी हेल्प कर सके वह करनी चाहिए |हर व्यक्ति को इस बारे में अपने हिस्से का काम करना चाहिए ताकि अप्रवासी मजदूर सुरक्षित अपने घर पहुंच सकें |

Migrant Workers Contribution:

समाज में हर वर्ग का अपना योगदान है देश व विश्व को आगे बढ़ाने का एवं हर व्यक्ति का सुरक्षित रहना बहुत जरूरी है इस संकट की घड़ी में |

हम सब की एक बड़ी जीत इस समय होगी अगर हम स्वयं एवं परिवार के सदस्यों को सुरक्षित रख सकें |

बड़े-बड़े विश्व युद्ध हुए पहले भी महामारी आई लेकिन कुछ समय बाद इंसान ने अपनी बुद्धि व मेहनत के बल से पहले से भी ज्यादा अच्छा काम करके दिखाया जो इस बार भी होने वाला है |

भारत विश्व गुरु बनने के सपने देख रहा है लेकिन आज के इस आधुनिक युग मे पूरा विश्व गांव के रूप में सिमट चुका है एवं विश्व के एक कोने से दूसरे कोने में शीघ्र खबर पहुंच जाती है |

आजकल जो खबर है प्रवासी मजदूरों को लेकर के टीवी में दिखाई जा रही है या अखबारों में लिखी जा रही है वह पूरे विश्व में पहुंचेगी और हमारे देश का जो प्रयास विश्व गुरु बनने की तरफ चल रहा है इस खबर से उसको झटका लगेगा|

पूरा विश्व यह सोचेगा कि अगर हम अपने परिवार के सदस्यों का भी ध्यान नहीं दे सकते तो हम कैसे विश्व गुरु बनेंगे या कैसे दूसरे देशों से जो कंपनियां भारतवर्ष में आना चाहती हैं वह आएंगी |

This Critical situation:

यह कठिन समय किसी भी हालत में राजनीति करने का नहीं है सबको साथ मिलकर इन अप्रवासी मजदूरों की जितनी हो सके सहायता देनी चाहिए ताकि यह अपने घर सुरक्षित पहुंच सकें |

आशा है आप मेरे इस विचार से सहमत होंगे एवं इस पोस्ट को जगह-जगह पहुंचाएंगे तकिए प्रवासी मजदूर सुरक्षित अपने घर पहुंच सकें |

आज वाकई अप्रवासी मजदूर बहुत ज्यादा संकट की स्थिति में है उन्हें मदद चाहिए कई मजदूरों ने तीन-तीन दिनों हजारों किलोमीटर पैदल चलने का प्रण ले चुके हैं अपने घर वालों के पास पहुंचने के लिए कृपया जितनी ज्यादा हो सके उनकी मदद करें |

मेरी इस पोस्ट को किसी भी हालत में राजनीति की पोस्ट ना मानकर इंसानियत के खातिर सहयोग दें |

Pollution”SSC Descriptive paper”

A challenge for India , According to a world Health Organisation (WHO) study , more than 5 lakh Indians die every year due to pollution. Pollution is the Contamination of environment from materials interfering with human health, The quality of life and natural functioning of ecosystem. Be it air water or noise pollution, the small looking issue is gravely affecting the lives especially in a developing country like India.

The major causes of pollution are rapid industrialization , population explosion and disregard to the plight of Mother Nature . Any pollutants be biodegradable (like seauage , wood ,papper) or non degradable (like plastic, chemicals ,industrial effluents) will cause contamination if present in excessive quantities. Once contamination occurs it is difficult or impossible to prevent then from causing Pollution .

Alarmingaly the affect of these pollutants is not limited to humen health (causing disease like cancer, asthma or chronic ailments) . It also cause harm to the natural flora and fauna there by affecting our food chain and ecosystem. A developing economy like India with huge population and limited resources cannot afford to bear the damage caused by population.

Over the years, we have extensively polluted our environment. Than fully how the awareness is spreading . Many green compaign are being organised by school and extending to big corporates . Parallels , various government initiative like formation National Green Tribunal (NGT) ,launching national mission for clean Ganga , promoting hybrid vehicles and banning polyethen bags is proving helpful to curb the problem of pollution . With all those cumulative efforts , we can envision to the lead the world by setting an example of green , sustainable and eco friendly nation . As a wise man once said ,” success is the some of small efforts ,repeated day in and day out”. Currently there are many step to follow the control the pollution as like electronic vehicles and solar system used.

Best Interview Questions and Answers of Data Communication and Computer Networks

Best Interview Questions and Answers of Data Communication and Computer Networks

Data Communication and Computer Networks Viva Questions & Answer

 

1.What is Data Communication?

Data Communication and Computer Networks in which Data Communication means the exchange of data between two devices via some form of transmission medium such as a wire cable.

For data communications to occur, the communicating devices must be part of a communication system made up of a combination of hardware (physical equipment) and software (programs).

2. What are the Characteristics of Data Communications?

The effectiveness of a Data Communication and Computer Networks system depends on four fundamental characteristics: delivery, accuracy, timeliness, and jitter.

  • Delivery: The system must deliver data to the correct destination. Data must be received by the intended device or user and only by that device or user.
  • Accuracy: The system must deliver the data accurately. Data that have been altered in transmission and left uncorrected are unusable.
  • Timeliness: The system must deliver data in a timely manner. Data delivered late are useless. In the case of video and audio, timely delivery means delivering data as they are produced, in the same order that they are produced, and without significant delay. This kind of delivery is called real-time transmission.
  • 4. Jitter: Jitter refers to the variation in the packet arrival time. It is the uneven delay in the delivery of audio or video packets. For example, let us assume that video packets are sent every 3D ms. If some of the packets arrive with 3D-ms delay and others with 4D-ms delay, an uneven quality in the video is the result.

.3. What are the Components of Data Communication?

The different components of Data communication are shown in the following figure.

  • Message: The message is the information (data) to be communicated. Popular forms of information include text, numbers, pictures, audio, and video.
  • Sender: The sender is the device that sends the data message. It can be a computer, workstation, telephone handset, video camera, and so on.
  • Receiver: The receiver is the device that receives the message. It can be a computer, workstation, telephone handset, television, and so on.
  • Transmission medium: The transmission medium is the physical path by which a message travels from sender to receiver. Some examples of transmission media include twisted-pair wire, coaxial cable, fiber-optic cable, and radio waves.
  • Protocol: A protocol is a set of rules that govern data communications. It represents an agreement between the communicating devices. Without a protocol, two devices may be connected but not communicating, just as a person speaking French cannot be understood by a person who speaks only Japanese.

4. What are Different Data Flow Directions?

Communication between any two devices can be simplex, half-duplex, or full-duplex.

  • Simplex: In simplex mode, the communication is unidirectional, as on a one-way street. Only one of the two devices on a link can transmit; the other can only receive which can be represented in the following figure. Keyboards and traditional monitors are examples of simplex devices. The keyboard can only introduce input; the monitor can only accept output. The simplex mode can use the entire capacity of the channel to send data in one direction.

Data Communication and Computer Networks Simplex

  • Half-Duplex: In half-duplex mode, each station can both transmit and receive, but not at the same time. When one device is sending, the other can only receive, and vice versa which will represent in the following figure.

Data Communication and Computer Networks Half Duplex

The half-duplex mode is like a one-lane road with traffic allowed in both directions. When cars are traveling in one direction, cars going the other way must wait. In a half-duplex transmission, the entire capacity of a channel is taken over by whichever of the two devices is transmitting at the time. Walkie-talkies and CB (citizens band) radios are both half-duplex systems.

The half-duplex mode is used in cases where there is no need for communication in both directions at the same time; the entire capacity of the channel can be utilized for each direction.

  • Full-Duplex: In full-duplex mode (also called duplex), both stations can transmit and receive simultaneously as shown in the following figure.The full-duplex mode is like a two-way street with traffic flowing in both directions at the same time. In full-duplex mode, signals going in one direction share the capacity of the link: with signals going in the other direction. This sharing can occur in two ways: Either the link must contain two physically separate transmission paths, one for sending and the other for receiving; or the capacity of the channel is divided between the signals traveling in both directions

 

Data Communication and Computer Networks.

One common example of full-duplex communication is the telephone network. When two people are communicating by a telephone line, both can talk and listen at the same time. The full-duplex mode is used when communication in both directions is required all the time. The capacity of the channel, however, must be divided between the two directions.

5. Different Types of Connections

A network is two or more devices connected through links. A link is a communications pathway that transfers data from one device to another. For communication to occur, two devices must be connected in some way to the same link at the same time.

There are two possible types of connections: point-to-point and multipoint.

  • Point-to-Point: A point-to-point connection provides a dedicated link between two devices. The entire capacity of the link is reserved for transmission between those two devices. Most point-to-point connections use an actual length of wire or cable to connect the two ends, but other options, such as microwave or satellite links, are also possible which are shown in the following figure.

Data Communication and Computer Networks

 

  • 2.Multipoint: A multipoint (also called multidrop) connection is one in which more than two specific devices share a single link as shown in the following figure.

Data Communication and Computer Networks

In a multipoint environment, the capacity of the channel is shared, either spatially or temporally. If several devices can use the link simultaneously, it is a spatially shared connection. If users must take turns, it is a timeshared connection.

6. Explain Types of Networks

Network category is determined by its size, ownership, the distance it cover and its physical architecture. The types of networks are local-area networks and wide- area networks. The category into which a network falls is determined by its size. A LAN normally covers an area less than 2 miles, a WAN can be worldwide. Networks of a size in between are normally referred to as metropolitan area networks and span tens of miles.

  • Local Area Network: A Local Area Network (LAN) is usually privately owned and links the devices in a single office, building, or campus (see Figure 1.10). Depending on the needs of an organization and the type of technology used, a LAN can be as simple as two PCs and a printer in someone's home office; or it can extend throughout a company and include audio and video peripherals. Currently, LAN size is limited to a few kilometers.

Data Communication and Computer NetworksLANs are designed to allow resources to be shared between personal computers or workstations. The resources to be shared can include hardware (e.g., a printer), software (e.g., an application program), or data.

  • Wide Area Network: A Wide Area Network (WAN) provides long-distance transmission of data, image, audio, and video information over large geographic areas that may comprise a country, a continent, or even the whole world. A WAN can be as complex as the backbones that connect the Internet or as simple as a dial-up line that connects a home computer to the Internet.

Data Communication and Computer Networks

  • Metropolitan Area Network: A Metropolitan Area Network (MAN) is a network with a size between a LAN and a WAN. It normally covers the area inside a town or a city. It is designed for customers who need a high-speed connectivity, normally to the Internet, and have endpoints spread over a city or part of city. A good example of a MAN is the part of the telephone company network that can provide a high-speed DSL line to the customer.

Data Communication and Computer Networks

7. Explain Types of Topologies

The term physical topology refers to the way in which a network is laid out physically.

Two or more devices connect to a link; two or more links form a topology. The topology of a network is the geometric representation of the relationship of all the links and linking devices (usually called nodes) to one another.

There are four basic topologies possible: mesh, star, bus, and ring which are shown in the following figure.

  1. Mesh Topology: In a mesh topology, every device has a dedicated point-to-point link to every other device. The dedicated link carries traffic only between the two devices it connects. The number of physical links needed in a fully connected mesh network with n nodes are, n(n - 1). However, if each physical link allows communication in both directions (duplex mode), we can divide the number of links by 2. In other words, we can say that in a mesh topology, we need n(n -1) /2 duplex-mode links. To accommodate that many links, every device on the network must have n – 1 input/output (I/O) ports to be connected to the other n - 1 stations which are shown in the following figure:

Data Communication and Computer Networks

       Advantages of Mesh Topology:

  • The dedicated links guarantees that each connection can carry its own data load, thus eliminating the traffic problems that can occur when links must be shared by multiple devices.
  • A mesh topology is robust. If one link becomes unusable, it does not incapacitate the entire system.
  • Another advantage of Mesh topology is advantage of privacy or security. When every message travels along a dedicated line, only the intended recipient sees it. Physical boundaries prevent other users from gaining access to messages.
  • point-to-point links make fault identification and fault isolation easy. Traffic can be routed to avoid links with suspected problems. This helps to discover the precise location of the fault and aids in finding its cause and solution.

Disadvantages of Mesh Topology:

  • Every device must be connected to every other device. So large amount of cabling and the number of I/O ports are required. So, the installation and reconnection are difficult.
  • The sheer bulk of the wiring can be greater than the available space (in walls, ceilings, or floors) can accommodate.
  • The hardware required to connect each link (I/O ports and cable) can be prohibitively expensive.

        2. Star Topology:

In a star topology, each device has a dedicated point-to-point link only to a central controller, usually called a hub. The devices are not directly linked to one another. Unlike a mesh topology, a star topology does not allow direct traffic between devices. The controller acts as an exchange: If one device wants to send data to another, it sends the data to the controller, which then relays the data to the other connected device as shown in the following Figure.

Data Communication and Computer Networks

  • Advantages of Star Topology: A star topology is less expensive than a mesh topology. In a star, each device needs only one link and one I/O port to connect it to any number of others.
  • A star topology is robust. i.e If one link fails, only that link is affected. All other links remain active. This factor also lends itself to easy fault identification and fault isolation.
  • Disadvantages Star Topology: One big disadvantage of a star topology is the dependency of the whole topology on one single point, the hub. If the hub goes down, the whole system is dead.
  • Although a star requires far less cable than a mesh, each node must be linked to a central hub. For this reason, often more cabling is required in a star than in some other topologies (such as ring or bus).

        3. Bus Topology: The preceding examples all describe point-to-point connections. A bus topology, on the other hand, is multipoint. One long cable acts as a backbone to link all the devices in a network which is shown in the following figure.

Data Communication and Computer Networks

Nodes are connected to the bus cable by drop lines and taps. A drop line is a connection running between the device and the main cable. A tap is a connector that either splices into the main cable or punctures the sheathing of a cable to create a contact with the metallic core. As a signal travels along the backbone, some of its energy is transformed into heat. Therefore, it becomes weaker and weaker as it travels farther and farther. For this reason there is a limit on the number of taps a bus can support and on the distance between those taps.

  • Advantages of Bus Topology: The main advantages of a bus topology is ease of installation. Backbone cable can be laid along the most efficient path, then connected to the nodes by drop lines of various lengths.

Disadvantages of Bus Topology:

  • The disadvantage of bus topology is difficult reconnection and fault isolation. A bus is usually designed to be optimally efficient at installation. It can therefore be difficult to add new devices. Signal reflection at the taps can cause degradation in quality.
  • A fault or break in the bus cable stops all transmission, even between devices on the same side of the problem. The damaged area reflects signals back in the direction of origin, creating noise in both directions

       4. Ring Topology:

In a ring topology, each device has a dedicated point-to-point connection with only the two devices on either side of it. A signal is passed along the ring in one direction, from device to device, until it reaches its destination. Each device in the ring incorporates a repeater. When a device receives a signal intended for another device, its repeater regenerates the bits and passes them along. A typical ring topology is as shown in the figure.

Data Communication and Computer Networks

Advantages of Ring Topology:

  • A ring is relatively easy to install and reconfigure. Each device is linked to only its immediate neighbors (either physically or logically). To add or delete a device requires changing only two connections.
  • A signal is circulating at all times (token) if one device does not receive a signal within specified period, it can issue an alarm. The alarm alerts the network operator to the problem and its location

Disadvantages of Ring Topology:

  • The main disadvantage of ring topology is unidirectional traffic can be a disadvantage. In a simple ring, a break in the ring (such as a disabled station) can disable the entire network.

      5. Hybrid Topology:

A network can be hybrid. For example, we can have a main star topology with each branch connecting several stations in a bus topology as shown in the following figure.

Data Communication and Computer Networks

If one link fails, only that link is affected. All other links remain active. This factor also lends itself to easy fault identification and fault isolation.

browserstack.com - Check your website’s responsive design on multiple desktops, tables, iOS and Android phones running different versions of operating systems.

If you changed the DNS servers for your domain, by changing registrars or DNS hosting in the last few days, flush your main domain name first before you flush any subdomains. OpenDNS also has a web tool for refreshing the DNS cache.

DomainTools - The tool monitors one or more web domains and sends email alerts when the domain is expiring, the domain gets renewed, the nameservers change or when the registrant information is updated for the domain.

How To Find Out How Much Actual Traffic a Website Gets

Would you like to know how much traffic (or page views) other websites in your niche are getting for competitive analysis? While it will be difficult for any third-party to accurately measure the traffic of a site, there are a bunch of traffic estimation services that can give you a better understanding of the popularity of a website. Here’s a list:

1. Similar Web - It started as a tool for finding similar sites but now offers a range of data including traffic analysis in a clean interface. You get to know the site’s traffic over time, the countries that are sending the most traffic, what search keywords are bringing the organic referrals, how much time users are spending on a site and so on.

2. SEM Rush - It offers plenty of information around search (organic) traffic for any website. Put in the website URL and you’ll instantly know how the site has fared in organic search over time. The data can be split by country, you get to know which sites are sending traffic and also the keywords that are bringing the most visitors. Open Site Explorer is another popular tool in this category.

3. Alexa - Enter the website’s domain and Alexa will reveal the ranking of that website based on a combined measure of unique visitors and page views. The rank isn’t based on a site’s traffic alone but is relative to the traffic of all other sites that are monitored by Alexa. Webmasters are often skeptical of Alexa number but the rank is still a good indicator of a website’s popularity over time.

4. QuantCast - Like Compete, you can use QuantCast to determine how many people have visited a selected site during a given period from desktop or mobile phone. For sites that have implemented the QuantCast tags, you get more accurate metrics including visitor demographics, traffic by country, and the split in mobile and desktop traffic.
