Communication


Cabling and CAT Fights


n today's industry, there is contention over which cables should be laid where, what cable is best for which applications, and what is the best bang for your buck. The reality is, that most enterprises barely pay attention to the kind of cabling that is being laid for their IT network, and are just trusting the technicians to give them what they need. As cabling is the support system for every thing from business services to bring your own device policies to cloud access, it might be an intelligent idea to start paying closer attention.
Cabling has come a long way in the last few decades, when Ethernet standards hit the market. Since then, data rates have grown exponentially and the 10 megabits per second that were seen as amazing in the '80's are now basically obsolete. In 2010, the IEEE 802.3b a committee came out with the new 40 and 100 GbE standards. Due to this overly quick ascension in the need for speed, it is no wonder that most people are a bit daunted by choosing the best cabling for their company.
With the increase in video standards, cloud computing, and bandwidth, the need for faster network speeds can often come down to the cable. Although CAT5e was seen as progressive and adaptable, it really should't be used by any business that wants to have an efficiently working facility for over 5 years. With the massive technological advances, every enterprise that is serious about their network should be using CAT6 cabling or above, unless they want to be ripping out their network cabling and replacing their system in the next few years.
There has also been an argument of late over copper versus fiber. Fiber is seen as a standard in the industry and is used in the main infrastructure and in conferences. It can sometimes provide better performance end points in high-end computing facilities and R&D operations, but it tends to be responsible for a smaller amount of installed ports in a LAN environment. Copper is seen as the better choice from an installer's view, and also when calculating expenses. Copper based interfaces are in the most accessible price range, beating out wireless and optical. And copper tends to have dominance in LANs up to 100 meters that support 10GbE.
When deciding between shielded and unshielded cabling, it's really more a question of the environment and your geographic location. If your cabling will be in a noisy area with a high amounts of electromagnetic activity, then go with shielded cable. Electromagnetic interference generally comes from things like fluorescent lights, air conditioners, photo copiers, generators and compressors. If your enterprise is expanding to another country or region where a shielded or unshielded is more common, you may have to go with the local standard just to get your work completed.
The future of technology is impossible to predict. Tomorrow someone could invent a new system that makes everything we are working with today feel like Etch a Sketches. The best chance any business has for staying in the game is to choose the best infrastructure they can reasonably afford.
For all your structured and network cabling needs.

 Data Recovery


Taking photographs is a hobby or activity that has captured the interest of millions of people worldwide. While many people study photography and invest in courses and equipment, intending to use them for a successful career of capturing images, others have also learned to become selective in their choice of cameras and would sign up for a variety of courses and workshops so they can take better photos of special events and specific subjects-even if they only wish to enjoy their photos for themselves and share them with friends online or in photo albums.
With so many people carrying cameras during birthday parties, concerts, family vacations, or even during an ordinary walk in the park or a quiet dinner with their spouse at a brand-new restaurant, it can be expected that dozens or hundreds of photographs are stored in the camera's memory card and in phones, computers, and other gadgets. Rather than promptly looking through the photos, organizing which ones to keep and which to delete, and printing the chosen photos right after the event, it is more likely that a person would leave the image files untouched inside the camera or device for a long period, with new photos being added with every new photo opportunity that arises. There is a significant chance that a photo can become deleted, and without a physical printout, the image of a memorable event can be lost forever. It's important to know how to recover deleted photos and prevent the loss of precious memories from taking place.
Photography lovers will be happy to discover that they can use available innovative software to recover deleted photos easily. Deleted pictures in formats such as JPEG, TIFF, BMP, CRW, NEF, and RAW, deleted movie and sound files in AVI, MPEG, MOV, and WAV filetypes, and deleted photos from reformatted memory cards, cameras, SD cards, USB memory sticks, PC disk drives can all be easily recovered using exceptional software designed especially for this purpose.
In order for this software to work better and to increase the chances of recovering an accidentally deleted image file, the most important thing to do is to refrain from saving any more new images files onto the memory card or device. Deleted files still retain a small amount of data which can be used to recover the file, but this data will disappear if new data gets written over it. Taking more new photos using the same camera or opening and closing applications and web surfing on a computer will cause disk activity which increases the risk of losing the data forever.
The deleted photo recovery software is inexpensive and safe to use; it is only designed to read disk or memory card data, ensuring the owner of the gadget that existing files will not be modified or damaged during the recovery process. Any photography enthusiast will be able to retrieve deleted photos from a camera, phone, or computer and preserve memories of special events and ordinary days alike for many more years to come.
For this software to work more effectively and to increase the chances of recovering unintentionally deleted image file, the best thing to do would be to refrain from saving any more new photograph files onto the device or memory card of the device. Deleted files still keep a small amount of data which can be utilized to retrieve the file, but this data will disappear if new data gets written over it. Learn more how to retrieved deleted photos using recovery software.

History of India


History of India


This article is about the history of the Indian subcontinent prior to the partition of India in 1947. For the modern Republic of India, see History of the Republic of India. For Pakistan and Bangladesh, see History of Pakistan and History of Bangladesh.

The history of India begins with evidence of human activity of Homo sapiens as long as 75,000 years ago, or with earlier hominids including Homo erectus from about 500,000 years ago.[1] TheIndus Valley Civilization, which spread and flourished in the northwestern part of the Indian subcontinent from c. 3300 to 1300 BCE in present-day Pakistan and northwest India, was the first major civilization in South Asia.[2] A sophisticated and technologically advanced urban culture developed in the Mature Harappan period, from 2600 to 1900 BCE.[3] This Bronze Age civilization collapsed before the end of the second millennium BCE and was followed by the Iron Age Vedic Civilization, which extended over much of the Indo-Gangetic plain and which witnessed the rise of major polities known as the Mahajanapadas. In one of these kingdoms, MagadhaMahavira andGautama Buddha were born in the 6th or 5th century BCE and propagated their śramanicphilosophies.
Most of the subcontinent was conquered by the Maurya Empire during the 4th and 3rd centuries BCE. It became fragmented, with various parts ruled by numerous Middle kingdoms for the next 1,500 years. This is known as the classical period of Indian history, during which time India has sometimes been estimated to have had the largest economy of the ancient and medieval world, with its huge population generating between one fourth and one third of the world's income up to the 18th century. Much of northern and central India was united in the 4th century CE, and remained so for two centuries, under the Gupta Empire. This period, witnessing a Hindu religious and intellectual resurgence, is known among its admirers as the "Golden Age of India". From this time, and for several centuries afterwards, southern India, under the rule of the ChalukyasCholas,Pallavas, and Pandyas, experienced its own golden age. During this period, aspects of Indian civilization, administration, culture, and religion (Hinduism and Buddhism) spread to much of Asia.
Kingdoms in southern India had maritime business links with the Roman Empire from around 77 CE. Muslim rule in the subcontinent began in 8th century CE when the Arab general Muhammad bin Qasim conquered Sindh and Multan in southern Punjab in modern day Pakistan,[4] setting the stage for several successive invasions from Central Asia between the 10th and 15th centuries CE, leading to the formation of Muslim empires in the Indian subcontinent such as the Delhi Sultanateand the Mughal Empire. Mughal rule came from Central Asia to cover most of the northern parts of the subcontinent. Mughal rulers introduced Central Asian art and architecture to India. In addition to the Mughals and various Rajput kingdoms, several independent Hindu states, such as theVijayanagara Empire, the Maratha EmpireEastern Ganga Empire and the Ahom Kingdom, flourished contemporaneously in southern, western, eastern and northeastern India respectively. The Mughal Empire suffered a gradual decline in the early 18th century, which provided opportunities for the AfghansBalochisSikhs, and Marathas to exercise control over large areas in the northwest of the subcontinent until the British East India Company gained ascendancy over South Asia.[5]
Beginning in the mid-18th century and over the next century, large areas of India were annexed by the British East India Company. Dissatisfaction with Company rule led to the Indian Rebellion of 1857, after which the British provinces of India were directly administered by the British Crown and witnessed a period of both rapid development of infrastructure and economic decline. During the first half of the 20th century, a nationwide struggle for independence was launched by the Indian National Congress and later joined by theMuslim League. The subcontinent gained independence from the United Kingdom in 1947, after the British provinces were partitioned into the dominions of India and Pakistanand the princely states all acceded to one of the new states.


Stone Age India

STONE AGE(7000–3000 BC)


The South Asian Stone Age covers the PalaeolithicMesolithic and Neolithic periods inSouth Asia. Evidence for the most ancient anatomically modern Homo sapiens in South Asia has been found in the cave sites of Batatotalena and Belilena in Sri Lanka.[1] InMehrgarh, in what is today western Pakistan, the Neolithic begins ca. 7000 and lasts until 3300 BCE and the first beginnings of the Bronze Age. In South India, the Mesolithic lasts until 3000 BCE, and the Neolithic until 1400 BCE, followed by a Megalithictransitional period mostly skipping the Bronze Age. The Iron Age begins roughly simultaneously in North and South India, around 1200 to 1000 BCE (Painted Grey Ware cultureHallur).


HOMO ERECTUS


Homo erectus lived on the Pothohar Plateau, in upper Punjab, Pakistan along the Soan River (nearby Rawalpindi) during thePleistocene Epoch. Soanian sites are found in the Sivalik region across what are now India, Pakistan and Nepal.[2]
Biface handaxe and cleaver traditions may have originated in the middle Pleistocene.[3] The beginning of the use of Acheulian and chopper-chopping tools of lower paleolithic may be dated to approximately the middle Pleistocene

THE COMING OF HOMO SAPIENS



Bhimbetka rock painting, Madhya Pradesh, India.Analysis of mtDNA dates the immigration of Homo sapiens to South Asia to 70,000 to 50,000 years ago.[5] An analysis of Y chromosome haplogroups found one man in a village west ofMadurai to be a direct descendant of these migrators.[6] These populations spread further to Southeast Asia, reaching Australia by 40,000 years ago. Cave sites in Sri Lanka have yielded the earliest record of modern Homo sapiens in South Asia. They were dated to 34,000 years ago. (Kennedy 2000: 180). For finds from the Belan in southern Uttar Pradesh radio carbon data have indicated an age of 18-17kya. Palaeolithic rock art is also well-known.
At the Rock Shelters of Bhimbetka humans lived throughout the Upper Paleolithic (10th to 8th millennia BC), revealing cave paintings dating to ca. 7000 BC; the Sivaliks and the Potwar(Pakistan) region also exhibit many vertebrate fossil remains and paleolithic tools. Chertjasperand quartzite were often used by humans during this period.


NEOLITHIC


The aceramic Neolithic (Mehrgarh I, Baluchistan, Pakistan, also dubbed "Early Food Producing Era") lasts ca. 7000 - 5500 BC. The ceramic Neolithic lasts up to 3300 BC, blending into theEarly Harappan (Chalcolithic to Early Bronze Age) period. One of the earliest Neolithic sites inIndia is Lahuradewa, at Middle Ganges region, C14 dated around 7th millennium BC.[7] Recently another site near the confluence of Ganges and Yamuna rivers called Jhusi yielded a C14 dating of 7100 BC for its Neolithic levels.[8]
In South India the Neolithic began by 3000 BC and lasted until around 1400 BC.South Indian Neolithic is characterized by Ashmounds since 2500 BC in Andhra-Karnataka region, expanded later to Tamil Nadu. Comparative excavations carried out in Adichanallur in Thirunelveli District and in Northern India have provided evidence of a southward migration of the Megalithic culture[9] The earliest clear evidence of the presence of the megalithic urn burials are those dating from around 1000 BC, which have been discovered at various places in Tamil Nadu, notably atAdichanallur, 24 km from Tirunelveli, where archaeologists from the Archaeological Survey of India unearthed 12 urns with Tamil Brahmi script on them containing human skulls, skeletons and bones, plus husks, grains of rice, charred rice and Neolithic celts, giving evidence confirming it of the Neolithic period 2800 years ago. This proved that Tirunelveli area has been the abode for human habituation since the Neolithic period about 3,000 years ago. Adhichanallur has been announced as an archaeological site for further excavation and studies.

Bhopal


Bhopal

is the capital of theIndian state of Madhya Pradesh and the administrative headquarters of Bhopal Districtand Bhopal Division. The city was the capital of the former Bhopal State. Bhopal is known as the City of Lakes[2] for its various natural as well as artificial lakes and is also one of the greenest cities in India.[3]
B-1 class city,[4] Bhopal houses various institutions and installations of national importance. Some of these include ISRO's Master Control Facility,[5] the CSIRAIIMS Bhopal,[6] National Institute of Fashion Technology (NIFT) AMPRIMANITIISERSPA,IIFMBHEL and NLIU. The city attracted international attention after the Bhopal disaster, when a Union Carbide India Limited (UCIL) pesticide manufacturing plant leaked a mixture of deadly gases including methyl isocyanate on the intervening night of 2 / 3 December 1984, leading to the worst industrial disaster in the history of industrialization and a loss of thousands of lives. Since then, Bhopal has been a center of protests and campaigns which have been joined by people from across the globe.


History




According to folklore, Bhopal is said to have been founded by the king Bhoja of theParamara dynasty (1000–1055 CE), who ruled from his capital at Dhar. This theory states that Bhopal was originally known as Bhojpal after the king and the dam ("pal") constructed by him. No available archaeological evidence, inscriptions or historical texts support the claim about an earlier settlement founded by Bhoja at the same place, although a temple complex constructed by him exists at Bhojpur, which is located 28 km from Bhopal. An alternative theory says that the name of the city was coined from the name of another king called Bhupala (or Bhupal).[7][8] (During theBritish Raj, the railway tickets printed in the city and the signboards on the railway station mentioned the name of the city as "Bhupal" in Hindi-Urdu and "Bhoopal" in English.)
In the early 18th century, Bhopal was a small village in the local Gond kingdom. The modern Bhopal city was established by Dost Mohammad Khan (1672–1728), an Afghan soldier in the Mughal army.[9] After the death of the emperor Aurangzeb, Khan started providing mercenary services to several local chieftains in the politically unstable Malwa region. In 1709, he took on the lease of Berasia estate, and later annexed several territories in the region to establish the Bhopal State.[10] Khan received the territory of Bhopal from the Gond queen Rani Kamlapati in lieu of payment for mercenary services, and usurped her kingdom after her death.[11]

During the early 1720s, Dost Mohammad Khan transformed the village of Bhopal into a fortified city, and acquired the title of Nawab.[12] Khan's support to the Sayyid Brothersearned him the enmity of the rival Mughal nobleman Nizam-ul-Mulk, who invaded Bhopal in March 1724, forcing Khan to cede much of his territory.[13] Dost Mohammad Khan and his Pathan associates brought the Islamic influence on the culture and architecture of Bhopal, the ruins of which can be found at Islamnagar near Bhopal. After Khan's death in 1728, the Bhopal state remained under the influence of the Nizam. The state also paid tribute to the Marathas, who defeated the Mughals at theBattle of Bhopal in 1737.

Nawab Faiz Muhammed Khan (1742–1777) moved the capital from Islamnagar to Bhopal. The state became a British protectorate in 1818. Between 1819 and 1926, it was ruled by four women – Begums – unique in the royalty of those days. Qudsia Begum was the first woman ruler, who was succeeded by her only daughter Sikandar Begum, who in turn was succeeded by her only daughter, Shahjehan Begum. Sultan Jahan Begum was the last woman ruler, who after 25 years of rule, abdicated in favour of her son, Hamidullah Khan. The rule of Begums gave the city its waterworks, railways, a postal system and a municipality constituted in 1907.[14]
Bhopal was the second largest Muslim state in pre-independence India after Hyderabad. After the independence of India in 1947, the last Nawab expressed his wish to retain Bhopal as a separate unit in March 1948. Agitations against the Nawab broke out in December 1948, leading to the arrest of prominent leaders including Shankar Dayal Sharma. Later, the political detainees were released, and the Nawab signed the agreement for Bhopal's merger with the Union of India on 30 April 1949.[15]
The Bhopal state was taken over by the Union Government of India on 1 June 1949. Sindhi refugees from Pakistan were accommodated in Bairagarh, a western suburb of Bhopal (now renamed to Sant Hirdaram Nagar). According to the States Reorganization Act of 1956, the Bhopal state was integrated into the state of Madhya Pradesh, and Bhopal was declared as its capital. The population of the city rose rapidly thereafter.
