A software development process is a structure imposed on the development of a software product. Synonyms include software life cycle and software process.

Domain Analysis

Often the first step in attempting to design a new piece of software, whether it be an addition to an existing software, a new application, a new subsystem or a whole new system, is what is generally referred to as “Domain Analysis”. Assuming that the developers (including the analysts) are not sufficiently knowledgeable in the subject area of the new software, the first task is to investigate the so-called “domain” of the software. The more knowledgeable they are about the domain already, the less the work required. Another objective of this work is to make the analysts who will later try to elicit and gather the requirements from the area experts or professionals, speak with them in the domain’s own terminology and to better understand what is being said by these people. Otherwise they will not be taken seriously. So, this phase is an important prelude to extracting and gathering the requirements.

Notebook, notebook computer, laptop, and laptop computer are different terms for a small computer, which is mobile, and weighing about 1 to 6 kg or 2.2 to 18 pounds, depending upon the model. In 1979-1980, Bill Moggridge of GRiD Systems Corp. designed one of the first laptops and named it as the GRiD Compass 1101. It featured the clamshell design where the flat display folded shut on the keyboard. In May 1983, Gavilan Computer Corp. introduced and first marketed as a laptop, known as Gavilan SC. About this same time, Sharp Corp.Ltd., announced their laptop Sharp PC-5000.

In 1989, Compaq introduced Compaq LTE, which was a laptop of a smaller size, about the size of an A4 paper notebook, and it popularly came to be known as a notebook computer or notebook. Thereafter the terms laptop and notebook began to be used interchangeably. Nevertheless, the terms, notebook and laptop are incorrect terms, as due to the heat, many laptops cannot be placed on top of the lap, and most notebooks are not the size of an A4 paper notebook. However, what manufacturers usually call as a notebook, end-users prefer to call it as a laptop; hence both the terms are used.

According to the functions and the models of notebooks, they are generally classified as: Ultraportables (screen is diagonally less than 12 inches, weight is 1.7 kg or less); thin-and lights (screen is diagonally from 12 to 14 inches, weight is from 1.8 to 2.8 kg); medium-sized laptops (screen is diagonally from 14 to 15.4 inches, weight is from 3 to 3.5 kg); and desktop replacement computers (screen is diagonally from 17 to 20 inches, weight is 4 to 6 kg).  Read more...

Information Technology Something New?

January 25 2010 by admin in IT |No Comments

When people hear the words “Information Technology,” the first things that come to mind are computers and the Internet. It may also bring up words like “network,” “intranet,” “server,” “firewall,” “security,” as well as more arcane expressions such as “router,” “T-1,” “Ethernet,” or the mysterious and exotic-sounding “VoIP” (pronounced “voyp”).


In fact, information technology is all of these things, and more. It’s hardly new, however. Information technology is as old as the brain itself, if you think of the brain as an information processor. As far as I.T. being a science, even that goes back as far as the earliest attempts to communicate and store information.


And that is essentially what information technology is: the communication and storage of information, along with the ability to process and make use of the information stored. In this chapter, we’ll begin with a brief history of I.T., what it comprises today, and the different major types of I.T. systems available today.


A Short History of Information Technology


As human societies have grown in size and complexity, so has the need to collect, store and transmit information. While it could be argued that brains represent a form of “bio-information technology,” Greek word “Tektra” – from which we get the word “technology” – really refers to scientific or mechanical knowledge, particularly that which involves the use of tools. Therefore, we’ll begin our journey with humans first attempts to record and transmit knowledge through mechanical means.  Read more...
