Digital Consultancy Service Centre

In $2024,$ during the summer vacations, the College of Business Administration will launch a Digital Consultancy Service Centre $($DCSC$).$ The DCSC will be managed and operated by Year $3$ MIS students from Sunday to Thursday between $10$:$00$am to $6$:$00$pm$.$ The aim of the initiative is to engage small and medium enterprises $($SME$\text{'}$s$)$ within the Eastern province with students who are specialists within the field of MIS.

There are two ways to contact DCSC; a toll$-$free number reaching the main headquarters on $+912345678$ and a messenger service via the DCSC website

Data and analytics lab located in building $600$ room $6215.$

Networking lab located in building $600$ room $6217.$

Security lab located in building A$7$ room $7204.$

Headquarters located in building A$7$ room $7110.$

Details about the divisional labs are as follows:

The data and analytics lab consists of $15$ desktop computers and $15$ tablets. Consultants are permitted to use their own devices to connect to the resources.

The networking lab has $20$ desktop computers and $5$ laptops. Consultants are
