Introduction of J2EE application server

An applications server helps in creating and implementing applications by successfully executing programs, scripts, and routines. Where java platform is concerned, application server often refers to J2EE application server and there are a host of different J2EE application servers.

Benefits and limitations of J2EE application server

Benefits: Since all the information and data is stored in one centralized location, therefore updating and upgrading the applications become that much more easy. A central point for storing data also ensures a high level of security where only service provides can have access to the data.
The performance of large applications improves drastically since the network traffic is limited to performance tier traffic.

Limitations: Since all the information is stored at one centralized location that is the servers, therefore if there is a technical glitch in the servers, application cannot be accessed. Many times, there is dependability of network connections and this can cause problem if there is a network outage.

List of various J2EE application servers There are a number of different kinds of J2EE application Servers. Some of the most popular and common ones that J2EE developers use while building applications include the following:

Apache Geronimo: Apache Software Foundation built this open source application server and its foundation is based on a microkernel called Java EE agnostic.

Glassfish Application Server: Sun Microsystems have developed Glassfish for the Java EE platform and is based on Sun and Oracle Corporations TopLink persistence system source code.

JBoss: JBoss is an open source Java EE based application server and since it is Java based therefore it can run cross-platform. It can run on any operating system that supports Java.

Websphere: This application server is an IBM product and is constructed from open standards such as XML, Java EE and web services.

Oracle OC4J: Developed by Oracle, this server’s core components include Oracle HTTP server and OC4J, OracleAS containers that deploy Java EE based applications.

J2EE Server Comparison WebSphere and OC4J are two of the most common java servers used for a applications and there does exist a couple of differences between both of them. Installing WebSphere is quite complicated and for different platforms a different configuration would be required. This is not the case with OC4J, which requires only a couple of minutes to get installed. WebSphere needs J2EE developers to use only proprietary packages and therefore it does not support the Servlet 2.3 API requirements. OC4J is completely compliant with Servlet 2.3 API. To install and run applications, WebSphere needs a database repository while OC4J can perform server configuration and J2EE applications development through easy to understand and configure .xml files

Microbiology Science Fair Project Ideas

q

Microbiology science project ideas include: how infectious diseases spread, how the immune system responds to a virus, how does penicillin fight bacteria, and how various disinfectants differ in killing a bacteria.

Science fair is nearing and you want to present something that is unique and challenging. If you want to have a different approach this time, you could try coming up with microbiology-themed science fair projects to impress your teachers. Here are some cool ideas to help you come up with a fantastic presentation and help you get a winning grade.

How infectious diseases spread

Demonstrate how communicable diseases spread into your system. Give a comprehensive detail about the specific pathogen of certain disease. Trace the transmission from carrier, to the portal of entry then to the susceptible host. You may need an illustration of the human body to demonstrate the process.

The reasons for having good quality and latest science lab supplies in schools are innumerable. Science labs help develop the interest of students in science and related subjects. They encourage students to investigate and understand the things that make up the world around them. Be it the weather, the environment, the food that they eat, the animals and plants that surround them, the various resources that they use for getting heat and light, and the functioning of their own human body, school science labs promote knowledge and awareness about science amongst students.

School science labs prepare future scientists and research scholars. Most dedicated scientists and researchers develop their life long interest in the particular field in their school science labs, as soon as they perform their first science experiment. In the absence of proper school science lab supplies and science laboratory equipment, schools canno prepare next generation scientists, engineers, and doctors.

Most medical and engineering colleges and universities require students to have completed necessary laboratory courses for getting admissions. Students get first-hand experience of using various basic science laboratory equipment and tools which eventually prepare them for advanced study in the field of science and technology.

Considering all these factors, it becomes imperative for schools to buy essential school science lab supplies. While the basic science laboratory equipment includes organ models, skeletal models, torso models, electricity and magnetism models, prisms, optics, microscopes, rockets, models for waves and sounds, chemistry kits, beakers, and jars, there are many other school science lab supplies that are required for developing scientific knowledge and reasoning amongst students.

Evolution Of Computer Technology

Teknologi Komputer

Today computers are an indispensable part of the lives of human beings but at one point of time there were no computers. Knowing the history of computers and how much progress has been made can aid us in understanding just how complicated the invention of the computer really is. Unlike other devices, the computer is the one invention that does not have any one specific inventor. Throughout the development of the computer, various people have made contributions to making a computer work. Some of these inventions were those of complete computers or other additions that helped revolutionize the computer that existed at that time. One such invention was the Integrated Circuit.

The single most important year in the history of computers is 1936. It was in 1936 that the very first computer was created by Konrad Zuse who called it the Z1 Computer. This was the first system that was fully programmable. Even though there had been devices that had come and gone before this but they didnt match upto it because of its superior computing power. Till 1942 no business saw profits and opportunities in computers. The first computer company was called ABC computers and was owned and operated by Clifford Berry and John Atanasoff. Two years later in 1942 came the Harvard Mark I computer which furthered the science of computing even more.

The age of computers saw its biggest change ever in 1953 with the introduction of International Business Machines known today as IBM. The company has always been a key player in the development of new systems. This was the first real competition to bee seen in the world of computing and helped to encourage faster development of better computers. The first contribution of IBM was the IBM 701 EDPM Computer. A year after this the first high level programming language was brought to the centre stage. This was a programming language that had not been written in ‘assembly’ or binary languages and was called FORTRAN which was written to enable more people to be able to program computers. In the year 1955 Bank of America, Stanford Research Institute and General Electric joined hands to introduce the very first computer for use in banks.

After that the evolution was quick. Computers like Apple I and II, The Scelbi, Mark-8 Altair, TRS-80, the Commodore Pet computers and IBM 5100 were the leaders of the sector of home computing. The micro processor was like the heart of the computer and began with the Intel 4004. from then it has evolved into todays Pentium IV, Dual core and Core 2 Duo processors. Along with the evolution in Hardware came the evolution in software which went from assembly languages to todays languages like C++, Java and PHP. There is more to come in this field and that more will surely be AI or Artificial Intelligence. The term was coined by John McCarthy and is today a major field of study.
