Abstract

A wireless LAN is a LAN that uses the air as a medium of transmission to permit data transmission among fixed, or moving computers. Wireless LANs operates either in infrastructure or Mobile Ad hoc mode. In infrastructure mode, devices are connected over the air to an AP which in turn connected to a wired network. Ad hoc mode does not require any central to operate. There are two different types of routing protocols for Mobile Ad hoc Networks (MANET): Reactive and Proactive. Ad-Hoc On-demand Distance Vector (AODV) is an example of Reactive routing protocol and in this paper we studied its performance by using Omnet++ simulator and INET simulation model.

Abstract

Nowadays technology is growing very fast. Today’s technology is being used in many things. One such thing is used in military forces. Military is a very strong part of India. So, some technology can be developed that can benefit these soldiers and save their lives. Military forces can use this robot for different purposes. In future, they can be used for communication, reconnaissance, surveillance. In order to use Robots for different purposes, research is continuously being carried out. Our main focus is to use these robots in military for war and peace. Our paper is a War Field Spy Robot. Spy Robot is controlled using remote. A wireless camera is mounted on this robot which captures the video of surrounding environment. A microcontroller PIC 16F877A is used to move the robot. To use the spy robot in the dark area as night, the camera set up with LED that is connected by lighting circuit.

Abstract

Cloud computing is the computing that is based on internet. Earlier, users download the application or software on a physical system, but with cloud computing, users can access the same kind of application or software through the net. Cloud computing is one of the fastest technology. Today lots of business organizations and educational institutions use cloud environment. Cloud computing is the most recent topic in Information Technology industry because of its flexibility in using the computing system. It provides everything as a service. Cloud computing is the fast growing concept promising to turn the dream of “computing utilities” into real things. It provides an easy and flexible way to store and retrieve a large amount of data ignoring the hardware requirements. The aim of this paper is to provide a better understanding of cloud, characteristics of cloud, Framework, benefits and limitations of cloud.

Challenges and Strategies of Information Communication Technology (ICT) Syllabus Implementation in Secondary Schools: A case study of Harare Urban Schools (2006 – 2010)

M. Mutema and Dr. F. Choga,JECET; March 2017- May 2017; Sec. B; Vol.6. No.2, 71-79.,[DOI: https://doi.org/10.24214/jecet.B.6.2.7179]

Abstract

This study investigated into the challenges faced by Harare Secondary schools in the implementation of Information Communication and Technology (ICT) syllabus from 2006 to 2010. In the study, the target population was 86 secondary heads of departments (HODs) of ICT. The sample size was 20 HODs. The descriptive survey was used. Questionnaires and face-to-face interviews were employed in data collection. The study showed that most of the HODs were trained ICT teachers. Most schools lacked adequate departmental budgets and shortage of computer laboratories, current hardware and software versions. They also did not have substitutes for electricity such as generators and solar panels for use during power cuts. The computer studies departments had problems of large classes, equipment breakdown, lack of technical support staff, faced competition for resources from other departments, no internet, negative attitude from heads of schools, inadequate parent and non-governmental support. This study recommended that Ministry of Education, Sports, Arts and Culture organize regular in-service training for teachers to improve skills and competence. It was also necessary for heads of schools, parents, pupils and other teachers to be educated on the importance of computers to improve interest and computer appreciation. There was also need for the heads of schools and parents to solicit for financial assistance. There was also a serious need to set strategies that could see a successful implementation of ICT syllabus in secondary schools.

Do Schools have adequate Information Communication Technology (ICT) Resources? A case study of Harare secondary schools (2006 – 2010)

M. Mutema and Dr.F. Choga

Abstract

This research study investigated the adequacy of ICT resources in Harare Secondary schools. In the study, the target population was ICT heads of departments (HODs)in 86 secondary schools. The sample size was 20. The descriptive survey was used. Questionnaires and face to face interviews were used to collect data. Most schools lacked adequate departmental budgets and enough laboratories for teaching and learning computer subjects. They had shortage of current hardware models and software versions. They also did not have substitutes for electricity such as generators and solar panels for use during power cuts. The computer studies departments had problems of equipment breakdown, lack of technical staff, and competition for resources from other departments, no internet, inadequate parent and non-governmental support. This study recommended fund raising activities to improve financial infrastructural shortfalls. There was need for government to motivate teachers to develop themselves professionally by subsidizing teaching degree and diploma tuition fees and also reducing the course duration to cater for the shortage of trained teachers.
