They are fast, but a supercomputer is faster.
If the mainframe were using TCP/IP then you don't need to do anything except route the traffic to it. If the protocols are not Ethernet on both the mainframe and the LAN then you would need a gateway to convert the protocols back and forth from the mainframe.
mainframe
Yes
Careers that work with computers can fall into the category of mainframe jobs. Anything having to do with designing computer software and programs goes along those lines.
Unix can be run on a variety of server, mainframe, and workstation devices.

Mainframes have a history spanning over 60 years: 1950s: Early large-scale computers such as IBM's 701 introduced centralized computing for governments and businesses. 1960s: IBM launched the System/360 (1964), creating a standardized mainframe family that could support different business workloads. 1970s–80s: Mainframes became central to banking, airlines, insurance, government, and large enterprises. Technologies such as CICS, DB2, and COBOL became widely used. 1990s: Mainframes evolved with stronger networking, virtualization, and enterprise database capabilities, while continuing to run critical legacy applications. 2000s–2010s: IBM's zSeries/System z platforms integrated Linux, virtualization, improved security, and web technologies. Today: Modern IBM Z systems continue to process high-volume, mission-critical workloads while integrating with cloud, APIs, DevOps, analytics, and AI. In short: Mainframes evolved from large centralized computers into highly secure, resilient enterprise platforms that still power critical digital services worldwide.
There are many places where one can find out more about how a mainframe works. This includes reading computing infrastructure books from your local library and blogs dedicated to the subject.
Yea, it works great!
