JSP, Servlet Context Initialization and Request Parameters, allows you to initialize the variables on startup in a global scope and get form or url parameters which are send via form submission or via dynamic url creation. In this article we are going to explain some key points of the servlet and JSPs. Now what is […]

HTTP protocol works with TCP/IP to transfer data, it uses the GET or POST request to retrieve the response from server, the response status is known by a code which tells what was the response or else if error occured what was the error and its cause. HTTP: HTTP is a application level protocol which is

Spiral model was originally proposed by Boehm.It is an evolutionary software process model which is a combination of an iterative nature of prototyping and controlled and systematic aspects oftraditional waterfall model.

The most fundamental calculation in the COCOMO model is the use of the Effort Equation to estimate the number of Person-Months required to develop a project. Most of the other COCOMO results, including the estimates for Requirements and Maintenance, are derived from this quantity. Basic COCOMO Basic COCOMO computes software development effort (and cost) as a
A switch is used in a wired network to connect Ethernet cables from a number of devices together. The switch allows each device to talk to the others. Switches aren’t used in networks with only wireless connections, since network devices such as routers and adapters communicate directly with one another, with nothing in between. A

What is Digital Computer ? Digital computer is any of a class of devices capable of solving problems by processing information in discrete form. It operates on data, including magnitudes, letters, and symbols, that are expressed in binary form i.e., using only the two digits 0 and 1. By counting, comparing, and manipulating these digits

Hubs, Bridges, Switches and Routers are used to build networks. If you are trying to design your own LAN (Local Area Network) at home, then you probably need to know what they do and the main differences between them. I will try to cover all that in addition to some networking details to cultivate the

The means through which data is transformed from one place to another is called transmission or communication media. There are two categories of transmission media used in computer communications. (1) Bounded/Guided Media. (2) UnBounded/UnGuided Media Bounded/Guided Media Bounded media are the physical links through which signals are confined to narrow path. These are also called guide media.
