Question:
what does register mean in computers? Does windows platform support multithreading?if not why? What's the difference between "Activex controls" and com,dcom



Replies:
Register, when talking about computers generally refers to a specific memory location within the CPU. Generally each CPU has several registers, and the calculations are performed on the values in the registers. Data is loaded from memory into the registers, and results are saved from the registers back into memory.

Windows does support multi-threading. Pre-emptive multi-tasking was the big addition to Windows95.

ActiveX controls are controls designed to make web-content more exciting and usable. Developers can write the controls and have them download and plug into Internet explorer and Netscape navigator.

COM and DCOM are technologies designed to allow developers to resuse binary objects in different applications. COM stands for component object model, and DCOM is for distributed component object model. Basically, with COM and DCOM, a reusable object is installed on a computer (with DCOM on a network), and then applications can request access to the object and use it.

Hope this helps,
