What system is the father of almost all modern multiuser systems?
There is no correct answer without qualifying which multiuser systems are being discussed. All modern operating systems have inherited traits and abilities from other older multiuser systems. There are multiple multiuser operating systems currently in use. IBM has their mainframe system (Z/os) as well as IBM i, both multiuser systems are unique from each other and from other systems. IBM also has AIX, a descendant of unix. Current unix systems go back to the original proprietary AT&T unix implementation in the 1970's and 1960's. Unix itself was modeled after a multiuser system called Multics. Linux was modeled after unix but written independently of it. Microsoft Windows NT was designed by Dave Cutler who brought his experience in developing OpenVMS with him. All other Microsoft Window implementations follow from that.
What type of environment does a mainframe computer need?
A clean cool environment without dust particles. Should be spacious.
What is a Minicomputer?
minicomputer are smaller than mainframe general purpose computer, and give computing power without adding the prohibitive expenses associated with larger systems. microcomputers are even smaller than minicomputers. the computer you are using to read this is almost certainly a microcomputer.
How many users can a mainframe computer handle?
Well, isn't that a happy little question! Mainframe computers are mighty powerful, my friend. They can handle thousands, even millions of users at the same time, all working together to create beautiful digital landscapes. Just like a painter with a big canvas, mainframes provide plenty of space for everyone to express themselves.
Where do computing terminals with no power get their ability to compute?
Computer terminals that have no computing power contend for access to the mainframe computer for computing that is then sent back to the respective computer terminal.
Why is windows systems important?
cause its your operating system without it your computer wont operate at all.
Why do you need system software and applications software on your computer?
Systems software is essential to make your computer operate. Without it, a computer cannot work. Applications are the programs that people use to do things on a computer, like word processors, spreadsheets, databases etc. Applications require a computer to have systems software to work.Systems software is essential to make your computer operate.

Will a 2001 dodge Cummins motor fit into a 2005 dodge Cummins?
While is would bolt into place, it will not work without major modifications. The fuel and computer control systems are completely different.While is would bolt into place, it will not work without major modifications. The fuel and computer control systems are completely different.
How do you secure your data?
Guardium for Mainframe is the only database auditing solution that provides 100% visibility into mainframe database activity without impacting business processes.
Is a supercomputer a mainframe computer?
No, they're not. Mainframe computers are those large and bulky machines used by organizations for a specific function. They were often used as servers. Microcomputers are among the most popular form factors of computer, and modern microcomputers are much more powerful than the gigantic mainframes of the past.
What is the difference between multiuser multitasking and multiprogramming?
Multiuser multitasking is what many mainframe computers were set up to do after about 1965, when it was realized that a computer was sitting idle for most of the time, waiting for the next input to arrive. By setting up a number of different terminals, each with its own address, and its own interrupt number, several different users could be working with a computer at the same time, running different programs, which required the computer to perform different tasks, such as creating data tables, calculating values based upon variables that were input, reading records and assigning each different record a value based upon a calculation which used variables included in the records, and so forth. Multiprograming is what an operating system such as Windows, or the Apple OS for Macintosh does, as well as many Linux operating systems. Several different programs are loaded into a desktop computer, such as a web browser, mail program, games, image editor, etcetera, and they are all opened up and running at the same time. Of course, most desktop computers were not powerful enough until recently to be able to actually manipulate an image while browsing the internet while running a game. However, the newest generation of processors, which are clocking over 2 gigaHertz, can easily perform all of these functions without appearing to hesitate at all.
What are the federal laws on computer hacking and how do they regulate unauthorized access to computer systems?
Federal laws on computer hacking include the Computer Fraud and Abuse Act (CFAA) and the Cybersecurity Information Sharing Act (CISA). These laws regulate unauthorized access to computer systems by making it illegal to access a computer without authorization or to exceed authorized access. Penalties for hacking can include fines and imprisonment.
