People communicate with computers on two different levels. On the upper level we have a very flexible system of windows: we can move them, resize, overlap or put side by side. However, starting an application immediately removes all the flexibility, and now you can work only inside the scenario developed by the designer of the program; you cannot move graphics or controls nor resize them. Here is a description of an extremely powerful mechanism that makes screen objects moveable and resizable. This not only significantly improves the existing applications, but it takes them to another level. This article explains in detail the construction and use of moveable and resizable graphical objects and applying the same technique to controls and groups of controls, which opens absolutely new possibilities for forms' customization and design of programs. Applications, based on such graphics and controls, become user-driven. This is absolutely new in computers - users' relation.

Semiconductors are 90% of the time made of Silicon, enhanced into P-Type or N-Type depending on needed polarities. P = Positive, N = Negative, Boron gas has excess negative electrons and is used in doping to create N-Type Silicon.

A computer can do everything a calculator can do, and more. On the other hand, a calculator can only be used for one thing- calculating.

The answer to this question depends on what you are using them for. If you need a device that is small, lightweight and inexpensive, then a calculator is the better choice. If you require a device that can do more than calculate numbers, doesn't need to be light weight, and price is not a problem, then a computer is probably better.

It depends on what kind of adapter you are speaking of. Netbooks are just smaller laptops and have many of the same ports and connections that a regular laptop would have. Chances are that it should work fine.

The benefits to this are the same as you are using right now reading this page. A time-sharing system (what we call a server nowadays) provides many many people the opportunity to use the system. Technically, even a standard PC is a time-sharing system, because you can run many different programs on it at a time (think Browser, iTunes, Anti-Virus, etc.).

The old mainframe systems had a card reader and an output. Only one set of cards could be run through at a time. So, if payroll was running through all 14000 employee's paycheck calculations, you had to wait until they were done. Modern mainframe systems have some time-sharing capabilities by allowing multiple processes to run on the system, but those processes are virtualized, rather than a true sharing system. However, the details of that can be left to others.

There are benefits and downsides to every type of system. In a mainframe-style system, all resources are available to the process being run, which benefits large data crunching operations (like payroll). The downside to a mainframe-style system is that only one process can run at a time in each virtual machine.

In a server-style system, all resources are shared among all processes. If a process "runs away" by using more processes than it should, then the other processes suffer, which the end-user sees as a server responding very slowly and/or "timing out". The upside to a server-style system is that you can serve web pages to thousands of people, while at the same time handling thousands of pieces of email.
