    Trade forms a vital part of the world economy. The analysis of data on trade and related parameters plays a pivotal role in developing policy inputs for efficient trade and sustainable development. It is evident that the success of any type of analysis depends on the availability of the suitable type of data. In general, time series, cross sectional and pooled data are the three types of data available for trade analysis. Time series data are characterized by observations collected at regular intervals over a period of time while cross-sectional data are data on one or more variables collected at the same point of time. The pooled data is a combination of time series and cross-sectional data. For example, panel data, which is a special type of pooled data is used to study the relationship between trade flows and trade barriers over time. In recent years, the quantitative and qualitative analysis of trade and the effects of policies have grown sharply. This was due to the advances in the theoretical and analytical techniques as well as increased computational and data processing power of computers

    Our lifestyles have undergone a sea change with the advancement in technology especially in the field of computers. Computers are an integral part of our lifestyles today and are found at offices, banks, homes, schools, colleges, hotels, shops etc. This advance in technology has made our lives easy and comfortable. For instance, we can execute a number of activities using computer based systems- we can write a draft on word processor and email it, make calculations using an electronic spread sheet and incorporate graphics, create a database of friends with their phone numbers, addresses and e-mail ids etc. This chapter gives overview of components of computer, different types of input and output devices, different types of memory, classification of computer, various computer generations, different types of computer languages and various applications in today’s arena

    Sampling methodology employed by CMFRI for monitoring the fishery and estimation of marine fish landings in India

    Fisheries sector plays a key role in Indian economy. The sector supports livelihood, nutritional security, and subsistence to large number of people as well as foreign exchange earnings. India’s coast line stretches about 8129 km. There are 1355 landing centres scattered along the coastline of the main land as per the records from National Marine Fisheries Data Centre at Central Marine Fisheries Research Institute (CMFRI). Marine fish landings take place almost all along the coast line throughout the day and sometimes during night. Under these circumstances, collection of statistics by complete enumeration would involve a very large number of enumerators and a huge amount of money apart from the time involved in collection of data. Therefore, a possible solution for quantifying marine fish landings is adoption of a suitable sampling technique. As, monitoring and assessment of the exploited marine fishery resources of India is one of the important mandates of the CMFRI, institute made attempts to evolve the scientific methods for collection of data on catch and effort, since its inception in 1947. Pilot surveys were conducted along the coastline of India and different sampling designs were tested

    In the existing sampling methodology, the interest is to estimate gear-wise, species-wise landings for the state in a month, fishing effort according to different types of fishing boats and also in terms of man hours. The analysis is carried out at CMFRI headquarters. Before the data is processed for analysis it will be ensured that the data collection is made as per the approved schedule, by checking the appropriate proforma. The responsibilities and functions of staff at the headquarters are data coding, estimation and database management. The data analysis is computerised and estimates are made using the software developed by the Fishery Resources Assessment Division of the Institute. The processed data are again counter- checked for errors. When discrepancies are detected, the estimation procedure is scrutinised in detail

    Fishing has been a traditional occupation of a section of people all over the world from time immemorial. In India, the fisheries sector contributes significantly towards strengthening nutritional security, income, employment, foreign exchange earnings and livelihood opportunities. These facts established the fisheries sector as an important enterprise of Indian economy. During the last six decades, Indian fisheries had made tremendous progress, with the annual fish production increasing from 0.75 million tonnes in 1950 to 6.4 million tonnes in 2006, indicating over eight fold increase during the period. As per the latest available data, marine fishery sector earns a foreign exchange of Rs. 8000 crores annually through seafood export

    Internet is a worldwide system of interconnected computer networks. It connects several millions of computers all over the world. There is no central computer. All computers are placed at different places and are connected to each other by phone lines, cables or wireless connections. Any two computers connected to the internet can exchange information. The internet is therefore a very fast and efficient way of sending information. According to recent statistics, there is an estimated 3,179,035,200 internet users worldwide. The number of Internet users represents nearly 40 per cent of the world's population. The largest number of Internet users is in China, followed by the United States and India. This chapter is organized as follows. It gives an introduction to internet and its applications in day to day life followed by basic requirements for connecting to internet. Subsequently a brief on World Wide Web, Web browsers, search engines, online safety measures are given. Lastly, a step by step procedure for creating e-mail ID is given in the chapter
