The directorate of Computer Services and Information Technology was a merger of three existing IT departments of the University, namely Computer Centre headed by Mr T. I Aiyelabegan as Director, Management Information System Unit (MIS) with Mrs O.V. Mejabi as Ag. Head and Unilorin Nigeria Universities Network Office(Unilorin NUNet) which had Dr. T.S. Ibiyemi of Electrical Engineering as head and chairman.
Each of the units had a board they report to prior to the merger and this resulted in the dissolution of the board in line with the new realities of the new ICT Policy and Strategic Plan put in place in 2001/2002 by the University through the Academic Planning Unit.
In 2002, the office of the Director of Academic Planning Unit was the convener of the first meeting of COMSIT as a merger with Mr. T. I. Aiyelabegan as the Director of the directorate, Mrs. J. Olorunfemi as head of Computer Centre, Mrs. O.V. Mejabi as head of MIS and Engr. Sogo Popoola as head of Unilorin NUNet office. After the merger these unit developed to fit the IT demands of the University community.
All other IT staff in academic department, laboratories, centres and units were pulled together to COMSIT to create a formidable IT team in order to enable an ICT driven academic environment at University of Ilorin in line with the new ICT Policy and Strategic Plan 2003-2008.
Computer Centre as a unit continued with her training programs and technical support for academic laboratories, MIS eventually developed its applications to deploy a Portal systems for students and staff in 2007/2008, while the NUNet office known for rendering/supporting email services through dial-up technologies, registered a fully qualified domain name for the University in 2003 and thereafter web services and campus wide networking began in earnest. Feat achieved by the merger cannot be overemphasized. The Portal development, the first of its kind in any Nigeria institution brought Unilorin into limelight as it was ranked the best in the country three(3) times and runners up in subsequent years by Webometics.info and 4icu.org ( now Unirank) between 2008 and 2014.
The visibility and activities brought about by web presence (webdomain and over 35 sub domains) could not (and cannot) be rivaled by other institutions. Other Units that sprang up such as the Network Operation Centre (NOC), made the campus wireless and campus wide fibre optics network connectivity available for Internet and Intranet services to about 204 physical buildings of the University on the permanent site and offsite such as the college of health sciences, school of preliminary studies in fufu, the mini campus( hosting the Open and Distance Learning-ODL, the Institute of Education-IOE, Unilorin Secondary School-USS and JUPEB) and other University’s Infrastructure. Staff and students were able to access Internet/Intranet services on the go.
Subsequently, a Helpdesk Unit also was put in place to render technical support to staff and students on the use of Portal and act as computer emergency response or computer security incidence respond team (CERT/CSIRT).
