My personal experince

                Software , instructions that tell a computer what to do. Software  comprises  the entire set of programs, procedures, and routines associated with the operation of a computer system . The term was coined to  differentiate  these instructions from  hardware such as  the physical components of a computer system. A set of instructions that directs a computer’s hardware to perform a task is called a program, or software program.  In 2000, Fred Shapiro, a librarian at the Yale Law School, published a letter revealing that John Wilder Tukey's 1958 paper "The Teaching of Concrete Mathematics" contained the earliest known usage of the term "software" found in a search of JSTOR's electronic archives, predating the OED's citation by two years. This led many to credit Tukey with coining the term, particularly in obituaries published that same year, although Tukey ...

Since the advent of the first computer different types and sizes of computers are offering different services. Computers can be as big as occupying a large building and as small as a laptop or a micro computer like mobile phone.  The four basic types of computers: Super computer Mainframe computer  Mini Computer  Micro Computer  SUPER COMPUTER:   The most powerful computers in terms of performance and data processing are the Supercomputers. These are specialized and task specific computers used by large organizations. These computers are used for research and exploration purposes, like NASA uses supercomputers for launching space shuttles, controlling them and for space exploration purpose. Super Computer The supercomputers are very expensive and very large in size. It can be accommodated in large air-conditioned rooms; some super computers can span an entire building. Uses of Super Computers: The supercomputers are very ex...

Howard Akin invented the machine in 1937 that could do complex calculations. So, Howard Akin is considere d the inventor of the computer. After seven years in 1944, the electric computer was used at Harvard University. Then after many inventions and developments in the fields of the microprocessor, silicon chip, computer language, operating system, storage device etc. and many generatio ns of computers, the computers have reached their present state. A computer system is made up of three main types of components: Input devices  CPU (Central Processing Unit) Output devices  Input Devices:   An input device is any hardware device that sends data to a computer, allowing user to interact with and control it. The most commonly used or primary input devices are mouse and key board.  However, there are dozens of other devices that can also be used to input data input the computer.  Input devices Input devices are important because they are wha...

The random forest is one of the most popular and most powerful supervised machine learning algorithm. That is capable of performing both regression and classification tasks. In general the more trees in the forest the more robust the prediction and thus higher accuracy to model multiple decision  trees to create the forest. Build up multiple decision tree using algorithm such as  Information gain GIGI index approach  Other decision tree algorithms Advantages: Here are some advantages of using random forests. Both classification and the regression task Handle the missing values and maintains the accuracy for missing data Will not over-fit the model  Handle large data set with higher dimensionality.  Disadvantage: Good job at classification but as good as regression  Very little control one what the model does  Application of Random forest: It use in banking sectors so these are for finding loyal customers and finding the fra...

Everybody has their own specific goals set to achieve in order to reach their long aspired lifestyle. For some, a prestigio us job with more than enough salary and for others heaps of money for a luxurious living. But in my point of view, other than money, an ideal life is accompanied by learning, lots of travelling and at the same time enjoying the journey with your loved ones along the way . To accomplish this aim I have planned to study in abroad. The reason why I came to this decision is due to the lack of opportunities available in my country in the computer engineering sector.  After doing research on some universities, I decided to take my bachelors degree in Universiti Teknologi Malaysia (UTM).  In 27th January, the  journey towards the next chapter in my life started when I finally said goodbye to my parents and relatives who came to leave me in airport. The flight departed at 12:30 pm from Hazrat Shahjalal International Airport. After taking my fa...
