Information Technology
Information technology is affecting culture and society in many important domains.
Information technology means using computers and computer software to acquire, convert process, transmit, protect and retrieve data. Computer science includes many fields, such as programming languages, computer graphics, hardware, and networks.
In 2006, some magazines rated software engineering as the best job in US. This appreciations in made in terms of growth, stress level, pay, creativity, flexibility in hours, working environment. It is also easy to enter in advance in the software engineering field.
Information Technology include many subfields, one of the most important is networking. The most common is the LAN (Local Area Network). This network covers a local area. It is designated to be used in offices, group of buildings, office, college, home or libraries. Usually, LANs are using Ethernet or Wi-Fi technology. The TCP/IP protocol is universal, and switched Ethernet is the most common. The public knows the Internet connection, the largest public network.
A spectacular and easy to use network is the wireless LAN or WLAN (wireless local area network). Wireless means that two o more computers are linked without cables. Radio waves are making possible the communication between computers in a restricted area, named basic service set. A laptop or PDA user can change his location without loosing the network connection. An access point is facilitating the permanent connection. This type of network becomes more and more popular; it is really efficient to use laptops and PDAs without loosing the Internet connection and enjoying the mobility advantages in the same time.
But the most attractive part in the computers’ world is computer programming. This means writing a set of commands or instructions that can be interpreted or compiled, transformed into an executable file. This can be execute, giving or no the expected results. Programming requires logic, first of all. But important knowledge of mathematics, science, physics, engineering, and art are required. Why art? A well designed menu in a customer application is more attractive and easy to use than a ugly one, even everything is correct and logic. And what about web design? It means imaging, animations and presentations. Without a good taste in arts, a web site will never attract visitors, and it is its main function.
In software engineering, programming is only a phase in the custom application development process. A computer can execute only the machine language programs. At the Information Technology beginnings, programmers worked only in machine code. It was very difficult and it was rapidly replaced by p-code, for example, used in the popular Java programming language, from Sun. The well known Microsoft software producer is also using the byte-code in the .net language family.
There are many programming languages. Some are already history, like COBOL or FORTRAN. Some are intensively used, like C and its versions. C is a compiled programming language. It was designed to create Unix, a popular operating system. C++ is a compiled programming language too. As its name is indicating, it is based on C and is great advantage is the object oriented programming. Is developed by Bjarne Stroustrup and one of its major advantages is the use of anew paradigm, the classes. Java, popular, easy to learn and having the ability to be run on many platforms, such as Linux, Mac OS and Microsoft, is an object oriented interpreted programming language. Not as popular as the other programming language, but spectacular and often used in Artificial Intelligence domain, Lisp is many times scripted too. Very popular, easy to learn and almost perfect to design customer application, Visual Basic is designed and developed by Microsoft. Every new version is bringing more functions.
But only a professional programmer can design customer application only with a good knowledge of one or more programming languages? The answer is no. System analysts are establishing the projects main functions, its concepts and the completion and implementation phases. The project must remain in its intended course and within its budget, delivered in time. Also very important is to have a friendly interface for unprofessional users and have a good relation with the customers even after the project is implemented.
Customer relationships management, human resources management, fleet management, web based systems can be accessed from any Internet browser on any platform. Fully integrated web based applications are now specifically developed for small or big enterprises. A major advantage is to provide reliable and secure communications, a lower cost for the infrastructure, a shorter time to market and flexibility of operations. Custom applications are designing software for a specific function or need. The difference between customer applications and packaged applications is that a general set of features never can be customized to fulfill every function or requirement. Custom application can design any feature the client needs, at low costs. In our days, offshore programming is making custom application affordable and efficient. Time and money are not anymore limiting factors.
Slate Information
Slate is formed through metamorphism, a process in which the tiny elements that make up a rock are pushed closer together to form a crystalline structure, also known as recrystallization of the stone. This all occurs while the stone is in a solid state, and the materials that make up the stone are not changed, they are merely repositioned to be closer to one another in a crystal pattern. Metamorphism can be caused by heat or pressure. The materials which undergo this transformation to form slate are generally a shale type sedimentary rock.
Slate forms in layers that easily cleave off in thin lines, generally known as Slaty Cleavage. During formation the original sedimentary rocks are forced down into these plains due to immense pressure. The resulting slate can be comprised of many different beds of sedimentary rock, all of which are now reoriented in the same direction.
While slate is generally a grey or grey-blue color, it can also have multicolored effects in its surface. These come from the various different beds of sedimentary rock of which it is comprised, often making this material a contrast of hues.
Slate is most commonly used for roofing because it can be sliced into thin layers. It is also very popular in flooring, countertops, and architectural applications, due to its durability, its natural beauty, and it’s relatively low cost. Its clefted surface makes it slip resistant, causing it to be popular in kitchens, bathrooms, and restaurants, as well as public hallways and other high traffic areas. It is also used in decorative home furnishing, fish tanks, and even in novel accessories such as board games.
Slate is found naturally in mountains. When it is quarried, it is usually done so in large blocks known as slabs. These blocks are then chopped up into smaller slabs for distribution. The size of the slab they can make is dependent on the relative strength of the type of slate. The inherent layering of this material makes some rather large sizes difficult to maintain and keep from cracking.
In stores, slate is generally available in tiles of various sizes including 16X16, 12X12, 8X8 as well as in slabs of various sizes, usually running to about 80 inches in length. Installations are generally done with mortar backing to even out varying thicknesses. Then grout lines are run along the joints of the stones. It is important to adequately seal and protect all tiles before grouting them.
Information Technology (IT) – An Overview
This present era is an era of information technology. This article is dealing with development of information technology in different facet of our life”
INTRODUCTION
In today’s world (IT) is all pervasive, everywhere, and in every facet of our day to day life. Prominently service sector involving railway, airlines, scientific and businesses establishments, banks, universities, schools, and most definitely in our homes. The phrase ‘information technology’ has many varying connotations in the same way as it has a wide spread presence. From the most mundane of things which a common person does to the most complex wizardry which only a techno savvy geek comprehends. Information technology can be seen and experienced in processes improving services to citizens and consumers (online transactions, bookings, university admissions, professional consultations, telecommunications, consumer products etc), increasing the productivity and efficiency of governments (computerization of government records, departments, e-cops), strengthening the legal and law enforcement systems (Judicial administration and Court Management) and in promoting the priority economic sectors (banking, agriculture, industry, marketing and the like), involving processes of manufacturing and production chain. Possibly the greatest impact Information technology has had is on blurring the time and geographical divide.
The penetration of the home computer or the personal computer phenomenon along with the Internet has increased the impact of information technology beyond our own imagination. Thus use of Internet has given the globe a shrinking effect. Every kind of information is only a few clicks away. In today’s world of competition -”information” is the key word to success. Availability of right information at the right time can make all the difference. Today relevant information outweighs the price of gold. The graphical user interface has simplified one of the most complex issues in the world. Indeed, the world is undergoing a second Industrial Revolution.
Information technology today touches every aspect of life, irrespective of location on the globe. Everyone’s daily activities are affected in form, content and time by the computer. Businesses, Governments and individuals all receive the benefits of this Information Revolution. While providing tangible benefits in time and money, the computer has also had an impact on everyday life, as computerized routines replace mundane human tasks. More and more of our businesses, industries, economies, hospitals and Governments are becoming dependent on computers. With the computer, the heretofore impossible has now become possible, The computer has allowed large volumes of data to be reduced to high-density, compact storage, nearly imperceptible to the human senses. It has allowed an exponential increase in speed, and even the most complex calculations can be completed in milliseconds. The miniaturization of processors has permitted worldwide connectivity and communication.
WHAT IS INFORMATION TECHNOLOGY?
The broad subject concerned with all aspects of managing and processing information, especially within a large organization or company. Because computers are central to information management, computer departments within companies and universities are often called IT departments. Some companies refer to this department as IS (Information Services) or MIS (Management Information Services). The penguin dictionary of computers defines it as “a portmanteau phrase to cover all aspects of the art or science of processing data to produce information”. It includes computer software, hardware, programs, and databases, semiconductor chips that put together process and produce the output. Output can be expressed in human readable form (printouts) or in machine readable form (series of electronic pulses) which are further used to control a any other machine, tool or device. Information technology also includes networking of computers and databases exchanging and feeding information between one another.
Basic understanding of and about technology law warrants proper grasp and appreciation about technology itself. Inherently technology law, like any other emerging facts of law, is purely inter-disciplinary in nature. Hence, it is now proposed to explain and introduce some of essential and relevant aspects of information technology.
Importance of information technology
The importance of information technology cannot be ignored by banking and insurance sectors, except at the cost of elimination from the competition. This is so because the use of information technology produces certain advantages, which are not available when the traditional and conventional methods of doing business are used. The use of information technology generates the following advantages and benefits:
