Computers as a multi-purpose tool in today’s era of globalization

THE use of computers has seen the introduction of extended entertainment, with a computer, a number of interactive games can be played. Children can also be seen enjoying themselves with some of these games making computers to all age groups in the society in terms of usage. You can watch movies and play music on computers, indeed it’s a multi-purpose tool. For school going children and adults, computers have become a source of information through extensive use of powerful search engines on world wide web like google search engines, MSN search, AltaVista search, yahoo search etc. Many societies have benefited from computer technology advancement through monitoring systems that have taken control of some routine manual processes. This can be done manually and it is very tiresome when it’s supposed to be measured over a long period of time at intervals, say twice in every minute. Introduction of an automated computer system would mean a computer awaits inputs, carry out some operations and provide an output. A variety of approaches are available to train people. Each has its place but affordable Computer Based Training (CBT) video technology makes it possible to train a large number of people with ease and efficiency. A major advantage of CBT is that learning can take place at the convenience of the consumer. With further advancement a number of repetitive operations have been taken over by computer systems thereby reducing the amount of work to be done by human beings. It’s also worth noting that regardless of these positive innovations to human life, there has been a hot issue on the negative impart of computer systems whereby fears are that if might result in retrenchment of thousands of employees as little human intervention will be needed where a computerized system has been introduced.

The fastest of today’s computers can perform more than a billion calculations per second. Even so, they are still too slow to approximate a human being’s higher intellectual processes such as the capability to reason, discover meaning, generalize and learn from the past experiences. Though computers are very powerful tool, but without qualified people and effective electricity supply to operate them, their value is limited. Essentially electric power drives the economy, political and social lives globally both in the developed as well as in developing nations. For the case of Tanzania, this fact occasionally manifest when power rationing is scheduled to cushion the acute power shortage amid a protracted drought that usually occurs, an aspect that cause water levels drop in most of the country’s hydro-electric power generating dams. The country’s industrial production sector relies on electric power mainly generated by hydroelectric plants whose production is far below the 550 megawatt of the national demand. But since the country has enormous potentials of the electricity power, an investment in the sector is a solution to the problem. In order to resolve the electric power shortage, there is a great need to diversify the resources of energy in the country. According to an expert, more hydroelectric power plants should be established in big rivers found within the in the country. According to the Chief Engineer in the Ministry of Energy and Minerals, Eng. Hosea Mbise, hardly 10 percent of the country’s population of approximately 40 million people has access to electricity. In rural communities only 2 percent have been reached. The government through its power policy of 2003 continues to work out strategies to increase the ratio of power consumption from the current 10 percent to 25 percent by 2025.
