Question:
The College was created in 1965 and the computer network came in the mid-1970's; it was a mainframe-based star network with a centralized mainframe computer supporting all of CUNY colleges. In the 1980's BMCC used VT-100 terminals to connect to multiple mainframes (to provide additional capacity).
? In the 1990's BMCC's computer network was modernized with PCs to replace the VT-100 terminals (which provided local computer power), some of these PCs were fitted with IRMA boards to connect to the mainframe computer. However, this option was expensive, so the college wired the computer labs with IBM 3270 terminals which provided a "native" connection to the mainframe. The ISO 7-Layer model was already in existence and the IBM Corporation implemented the 7-Layer model using a protocol called "Systems Network Architecture (SNA) which was proprietary. This SNA protocol was in use here and all IBM networks.
? The year 2000 was a major transition; PCs became more powerful and this allowed for applications to be written in a "client - server" processing mode.. Linux servers became more popular than IBM mainframes (mainly because of cost) and to readily connect to Linux/Unix servers (as well as IBM Mainframes) most computer networks adapted the TCP/IP networking protocol.
? The TCP/IP protocol readily supported web-based applications and networking evolved into the web services model in use today. This transition was no different here at BMCC. About twenty years ago, the College implemented its first 10 Base-T Ethernet network (using a bus topology to connect classrooms and a star topology within each classroom):
