In this contemporary world, computers and information technology (IT) are the key factors influencing the growth by accelerating innovations in almost all sectors. Introduction of new computational methodologies and architectural optimizations in the hardware and software arena is leading to more powerful automations in both industrial and public sectors shaping economic, social and cultural growth. The optimum use of emerging technological developments in the area of computers and information technology also play an important role in supporting human health care and medical sciences. The availability of advanced modelling methodologies with high performance algorithms and data processing techniques provides an appropriate platform for understanding natural phenomena and environmental issues. These are becoming possible due to outcomes of various research and development activities being conducted by scientific communities around the world. These research findings should be shared with the public for enabling further developments. Since 1998 the series of International Conferences on Computer and Information Technology (ICCIT) being organized by different public and private universities in Bangladesh has been successful in bringing together academics, researchers, IT professionals and IT managers to disseminate state of the art research activities and outcomes in these fastest growing fields.

  This Special Issue of the Journal of Computers presents nine papers. Two of these papers are selected from the first International Conference on Advances in Electrical Engineering (ICAEE) held at Independent University, Dhaka, Bangladesh in December 2011. The remaining seven papers are selected from the Fourteenth International Conference on Computer and Information Technology (ICCIT 2011) held at the American International University (AIU), Dhaka, Bangladesh during December 22-24, 2011. The first one of the ICCIT conference series was held at Bangladesh University of Engineering and Technology in 1998. Since then the ICCIT conference has grown into one of the largest computer and IT related research conferences in the South Asian region, with participation of academics and researchers from many countries around the world. Authors are required to submit full length papers to the conference for review. A double blind review process is followed whereby each paper is reviewed by at least two independent reviewers of high international standing. The acceptance rate of papers in recent years has been around 35% or less. This is an indication of the quality of work presented in the papers accepted for the conference. The proceedings of ICCIT have been included in IEEExplore since 2008, enhancing the visibility of research activities of the participating researchers with possible citations in a wider sense.
