Developments in Information Technology

Information technology is a magic science. During the past one and half decade, IT has emerged a lot and is growing in an unexpected manner. The information technology today is integrated into almost all the departments, for example, medical or health care, mechanical, electrical, civil, machinery, space, information broadcast, robotics, construction industry. IT is used almost in all the fields. Use of the information technology in various fields gets the job done faster and easily, saves money for the businesses. Information technology is also used in the banking sector. Almost all the banks implement the software to process transactions, store the data and for many other purposes. Securing the data is also very important when we are using various software applications.

Information Technology in Banking:

Many internet based and network based and offline based IT applications are used by the banks. The software are used to process money transactions, storing the user data, storing the transaction data, providing the various kinds of information through online websites to the user and much more. The bank applications can be accessed by the end user from any where using the online websites. Using the online applications, the end user can view the current amount, amount sent, amount received and other various types of transactions.

IT in Health Care:

IT is used in most of the health care equipments. The doctors use network based healthcare software application to store the health records of the patients. These network based applications can send messages to the users. Sometimes these health records can help the doctor in the future to review the patient records and suggest a better medication. Many electronic health care devices also use many software application to display scans, store user data, suggest medications and the applications cannot be counted with a human hand.

IT in Space:

Information technology is also used for space missions, for example NASA used Java, Python and many other software technologies to produce various applications that help their space missions.

IT in Construction:

Various project management applications like primavera, Microsoft project are used for storing and reviewing the project data in the construction field. The construction also use Microsoft office product heavily. Now-days SAP also called as System Application and Products which is an enterprise relationship product is being used extensively in various construction departments and large enterprise level companies.

IT in household:

We in our home personally use many kinds of software for playing movies and songs, use many enterprise software for our daily work. Most of us have at least one computer in our home. The television set, the iPod, the iPhone, Samsung Galaxy S2 all are powered by software combined with hardware.

Despite the internet becoming increasingly ingrained in our culture, excepting engineers and enthusiasts, few people seem to know much about how it works. It is clearly a very complex piece of technology. However, on a simple level, it is just groups of smaller networks that communicate with each other. There are several large companies, which are refereed to as level 1 networks; they handle the bulk of the traffic. The rest of the ISPs - whether they provide their service through cable or mobile satellite internet - communicate with the rest of the world through these level one networks.

There are now dozens of different ways to access the web. However, the one that started it all was dial-up. This uses a modem to convert digital signals (data) into analogue signals, in the form of sound, which allows the data to be transmitted over the phone network.

Comparatively speaking, the internet is a very young technology, and most people can remember dial-up; in fact many people around the world still use it. However, it is a technology on its way out. More people each year are switching to broadband technologies.

Broadband is not a very specific term; it can refer to a number of technologies, and a large range of different speeds (bandwidth). However, the two dominant broadband technologies are cable and ADSL broadband. The first, ADSL, allows data to be transmitted in a digital form (i. E. Not being converted into sound first) over a traditional copper telephone line.

The data does not interfere with the sound on a telephone call, and inexpensive filters separate the data and audio streams at the end point. The benefit of this is that the broadband service can be provided over an existing phone line.

However, one of the main drawbacks is the variable performance. In fact, the further away one lives from the local telephone exchange, the poorer the signal will be. It follows that the poorer the signal is, the slower the connection will also be.

As an alternative to this, in areas where it is available, many people choose cable broadband. Instead of being provided over copper telephone lines, cable is provided over a cable TV network, which may also be many of copper, but is now more likely to be made of fiber optic cable. The very last part of the network - between the cabinet (or multiplexer) in the street and the customer's home - is often made from copper co-axial cable, rather than fiber. This is why cable TV / broadband networks are often refereed to as "hybrid fiber co-ax" networks.

These two services are now the most common digital communication technologies in the world. However, they require a person to live a suitable distance from a local exchange. For those living in very rural areas, or adventurous people who wish to take their service to a remote place, technologies such as satellite internet are often a good choice.

We have moved from using dial-up modems to ADSL and mobile satellite internet in less than 10 years. The internet is a marvel of technology, and demonstrates that with cooperation between people and countries, incredible feats of engineering are possible.
