    Computers are increasingly present in most childhood education settings in Ghana. Very young children have shown comfort and confidence in using computers in Ghana. The computer also offers unique opportunities for learning through exploration, creative problem solving, and self-guided instruction. This paper presents a review of the level usage of the computer and the internet by teenage girls in Ghana. The amount of time and the types of activities that these girls engage in while using computer and internet.

    The information superhighway pinnacled as the internet has significantly altered many aspects of life especially in the areas of banking, commerce, work and employment, transportation, entertainment, community life, family life, human relationships, education, freedom, democracy, and many more. The Internet Technologies provide communication tools and services, with distinct characteristics and communication capabilities that allow individuals and organizations to use them either independently or jointly, to achieve multiple communication goals. While the internet technology continues to develop as an important aspect of Ghanaian life, it becomes increasingly important to understand the behaviors of internet users in order to effectively market to its target audience. The objective of this study is to review the adoption and penetration of internet usage in Ghana and evaluate the current internet usage by various working folks in the country. The study shows that 45.6% use internet ...

    Programming with locks is very difficult in multi-threaded programmes. Concurrency control of access to shared data limits scalable locking strategies otherwise provided for in software transaction memory. This work addresses the subject of creating dependable software in the face of eminent failures. In the past, programmers who used lock-based synchronization to implement concurrent access to shared data had to grapple with problems with conventional locking techniques such as deadlocks, convoying, and priority inversion. This paper proposes another advanced feature for Dynamic Software Transactional Memory intended to extend the concepts of transaction processing to provide a nesting mechanism and efficient lock-free synchronization, recoverability and restorability. In addition, the code for implementation has also been researched, coded, tested, and implemented to achieve the desired objectives.
