How to make Mainframe Computer

Mainframe technology is more powerful today than it was three generations ago.

With the advent of new technology, it would seem that mainframe computers are a relic, but they are still with us. The difference is modules that took up the size of 10 standard office spaces have been reduced to a small unit with triple the processing power. The creation of the mainframe ushered the world into the Information Age.

Third generation computers were created for multiprocessing and multiprogramming. Honeywell created the first dual processing mainframe system with advanced math functions for the science and business sectors. This generation of computers introduced the personal computer to consumers and server-based technologies modeled after mainframes, which became smaller and more compact. An example is the IBM AS/400, which can be purchased as a desktop server. Today's mainframe standard is the IBM Blue-Gene/P, a system that has 73,728 processors and 850MHz processing power. The current IBM mainframe also supports midrange, LAN (Local Area Network) and PC-based systems.

A small laptop can mimic a mainframe.

Large businesses and organizations use mainframes to secure, centralize and reduce the cost of computer resources. Though personal computer users might not possess the same technical know-how, hardware and software as these behemoths, they can still emulate the end results of using a mainframe. Microsoft gives system administrators -- or owners -- of its Windows operating system the ability to create several user accounts on one machine. Additionally, these established users can log into their personal Windows accounts one by one and have programs and applications running during simultaneous active logins, similar to how a mainframe operates.

1.) Log into Windows under an administrator's account. Click "Start." Type "User Accounts" in the search box at the bottom of the "Start" menu. Press "Enter." Click "Manage Another Account."

2.) Select the "Create a New Account" link. Type in the user's new account name in the text box. Fill in the "Standard User" radio button. Click "Create Account." Repeat this step until individual accounts are established for all computer users. Close the User Accounts window.

3.) Click "Start." Select the right arrow next to the "Shut Down" option on the "Start" menu, but don't shut down the PC. Choose "Switch User." The administrator's account will remain logged into Windows, with all programs running in an active or idle state.
4.) Give the users their account names. Instruct each user to click on their name on the Windows login screen. Once logged in, they will type "User Account" in the search box at the bottom of the "Start" menu and then press "Enter." They must then click the link to create a password.

5.) Instruct each user to click "Switch User" instead of "Shut Down" when they need to exit their own login so that another user can log in to use the computer.
