What is Dual Core Technology?

  Dual core technology refers to two individual microprocessors on a single die cast chip. This is essentially two computer processing units (CPUs) in one. The advantage of a this type of chip is that tasks can be carried out in parallel streams, decreasing processing time. This is referred to as thread-level parallelism (TLP) .TLP is also possible on motherboards that can accommodate two separate CPU dies. When TLP is accomplished in a single CPU through dual core technology, it is called chip-level multiprocessing (CLM) . In CPUs with more than one core, each microprocessor generally has its own on-board cache, known as Level 1 (L1) cache. L1 cache significantly improves system performance, because it is much faster to access on-chip cache than to use random access memory (RAM). L1 cache is accessed at microprocessor speeds. Dual core chips also commonly feature secondary shared cache on the CPU, known as Level 2 (L2) cache. Motherboards may also have a cache chi

What Is the Difference between a Sprocket and a Gear?

The biggest difference between a sprocket and a gear is how each works on a functional level. Both tend to be grooved wheels used in machinery, and their basic appearance is often really similar — but how they operate and what, exactly, it is they do tends to be really different. In general, a gear is a toothed wheel designed to mesh with other gears and transmit movement to them , which in turn can cause movement elsewhere. A sprocket, conversely, is a toothed wheel designed to engage and directly move a flexible indented or perforated item, like a chain or belt. The applications of each are different as a result. Sprockets are most common when there’s a moving belt or chain that is contained, as is commonly the case in bicycles, conveyor belts, and film projection reels. Gears are typically preferable in all other scenarios, cars and heavy machinery included. Not only are gears more universally useful, but they also aren’t as likely to need repairs or re-fittings
