What is the difference between loose leaf tea and filter bag tea

A few major differences:

1) The quality of the tea in filter bags tend to be among the lowest. Nowadays, some merchants have decided to nike free 5.0 offer premium filter bag teas with higher grades of leaf, although in general these are still not as good as loose leaf tea. (Note: loose leaf tea has a huge variety of grading as well but I will not cover that in this question. Beware of merchants who claim that all loose leaf teas are leaf

2) One effect of this quality difference is that tea from loose leaves tastes generally better than tea from filter nike free 5.0 bags. First, because the fuller leaves allow for a more complex and interesting flavour, and second because the intensity of flavour reached is higher, without introducing as much astringency into the tea liquor. Another related effect is that since filter bags contain smaller pieces of leaf, they yield their flavour more quickly and require less steeping time (longer steep times will result in astringency and bitterness). All these tend to result in a significantly higher price for loose leaf tea compared to bagged tea (although some of the markup is also due to other unrelated factors like branding and snobbishness, particularly for posh retail brands which are often not the best places to go to for loose leaf teas!).

There been a recent fad of using loose leave teas in fancy filter bags (pyramidal mostly) which is said to be a way of combining the good taste of loose leaf and the convenience of filter bags (the fancy bags are said to allow loose leaves to expand much better than traditional nike free 5.0 filter bags). Naturally this cannot be for flavour than just allowing loose leaves to brew in a pot, but it is an option these days nike free 5.0 , hence the difference between filter bag tea and loose leaf tea.




Memory mapped I/O (MMIO) and port I/O (also called port mapped I/O (PMIO) or isolated I/O) are two complementary methods of performing input/output between the CPU and peripheral devi nike free 5.0 ces in a computer. Another method, not discussed in this article, is using dedicated I/O processors commonly known as channels on mainframe computers that execute their own instructions.

Memory mapped I/O (not to be confused with memory mapped file I/O) uses the same address bus to address both memory and I/O devices, and the CPU instructions used to access the memory are also used for accessing devices. In order to accommodate the I/O devices, areas of the CPU’s addressable space must be reserved for I/O. The reservation might be temporary the Commodore 64 could bank switch between its I/O devices and regular memory or permanent. Each I/O device monitors the CPU’s address bus and responds to any of the CPU’s access of address space assigned to that device , connecting the data bus to a desirabl nike free 5.0 e device’s hardware register.

Port mapped I/O uses a special class of CPU instructions specifically for performing I/O. This is generally found on Intel microprocessors, specifically the IN and OUT instructions which can read and write one to four bytes (outb, outw, outl) to an I/O device. I/O devices have a separate address space from general nike free 5.0 memory, either accomplished by an extra “I/O” pin on the CPU’s physical interface, or an entire bus dedicated to I/O. Because the address space for I/O is isolated from that for main memory, this is sometimes referred to as isolated I/O.

A device’s direct memory access (DMA) is not affected by those CPU to device communication methods, especially it is not affected by memory mapping. This is because by definition, DMA is a memory to device communication method that bypasses the CPU.

Hardware interrupt is yet another communication method between CPU and peripheral devices. However, it is always treated separately for a number of reasons. It is device initiated, as opposed to nike free 5.0 the methods mentioned above, which are CPU initiated. It is also unidirectional, as information flows only from device to CPU. Lastly, each interrupt line carries only one bit of information with a fixed meaning, namely “an event that requires attention has occurred in a device on this interrupt line”.
