Understanding CPU

Understanding CPU can we know in brief from the stands for the CPU itself. CPU stands for Central Processing Unit or CentralProcessing Unit. In laymen, we often refer to it as the processor.Because it is a data processing center in a computer, the CPU can be likened to a brain of the computer itself. Fast or slow the performance of a computer simply determined by the quality andtechnology of the CPU being used.

The workings of the CPU according to wikipedia, is almost equal to the workings of a calculator. It's just data processing that is able to handle a more powerful CPU and probably more complex than can be handled by a common calculator. A CPU can process datain addition to arithmetic, can also manage the data that is logic.Simply put, in addition to counting, the CPU can compare.
But sometimes a different understanding of the CPU when used ineveryday language. A youth organization leader who asked hissubordinates "Monitor and keyboard already exists, but whyCPUnya not taken?"

CPU can be sure that the word used above is not referring to theCPU as a processor, but as a unity Processor CPU, Mainboard,RAM, hard drive installed in a casing like the picture beside.Exactly is meant by the chairman of the youth in the story above is acomputer tower (a term referring to wikipedia). But perhaps for reasons of convenience, the term CPU is used to save the word.Thus we see at least two meanings or two CPUs depending on thecontext of understanding the conversation.

Unfortunately, the card SD card, memory and storage configurations defined yet and not limited to slots, but still only a flash memory and RAM of 64 GB, available of 2 Gigabytes disproportionate number represents a $ 999 entry-level configuration, does not remain. Our storage and 128 gigabytes of RAM is $ 1,199 and has four gigabytes configuration. 

This is my MacBook Air, the biggest change is how to sell. For both the current entry-level white MacBook from the Apple MacBook Air laptop (with a big drop in more than one person's laptop), and there is no more than $ 999. $ 999 Apple MacBook 11 in. The MacBook Air has set the most advantageous. 

For 2011-11 the air in. undoubtedly, fall in the 2010 version is being developed. This is for everyone, the MacBook? If you can not live yet is still relatively limited storage air. The full-size notebook, 13-inch MacBook Air, or better battery life and performance to the absolute mobility, however, a full-featured, 13 in. MacBook Pro, which can be mistaken for one who can beat the air 11 inches.
