computer technology and devices








do you know that we can control the computer with our brain it is very simple with help of technology we are now able to controle the computer with help of our brain
and the product which is used to do all this task for us is available by many vendor online
we can get this type of device from the amazon as well as from the other online stores and
any of you is interested in
playing games with the help of yor brain we must buy it

A CPU gets its name because it is central to a computer's operation in its role of either executing or controlling all data transfer and processing; it processes data and it is a single self-contained chip or unit. The CPU's speed and performance are directly related to a PC's ability to do its work, making it by far the most vital of computer components. The question of how microprocessors do the things they do might never occur to some, and to others it might seem slightly akin to psychoanalyzing a genie that has just granted them three wishes. To be sure, the technology under a microprocessor's hood is complex and highly sophisticated, but with an understanding of a few main components, figuring out how they work is easier than it would seem. Do The Math. Before delving into the microprocessor's intricacies, it is important to form a basic understanding of how it "thinks." Whereas humans use letters, words, and a number system that includes 10 digits (0 through 9) to communicate ideas and thoughts, at the most basic level computers can only understand two digits, 0 and 1. This base-two math system is known as binary, and even the 1s and 0s are merely our translation of the values the computer understands. To a computer, 1 and 0 represent either yes or no, true or false, and are created by sending electronic pulses that either pass through a transistor (please see the "Bringing It All Together" section later in this story) to indicate "yes" or "1" or are impeded to indicate "no" or "0." Every instruction a microprocessor receives, whether programmed permanently into its instruction set or given to it as it processes an external and temporary set of instructions (software), is made up of commands that computer programmers have compiled into specific programming languages (for example, BASIC, COBOL, C, and others). In order to understand these commands, however, computers must first translate them into binary, a process that takes place within a microprocessor's decode unit. For this to work, each letter of the alphabet and each base-ten number must be assigned a binary equivalent made up of ones and zeros. To this end, programs established different systems to form standard character sets that consist of letters and numbers translated into their binary equivalents. Systems such as EBCDIC(Extended Binary-Coded Decimal Interchange Code) and ASCII (American Standard Code for Information Interchange) give letters a numerical equivalent (for example, M equals 77 in ASCII), which is then translated into a binary form computers understand. So each time you press and hold the Shift key and the m key on your computer keyboard, it sends a signal to the computer's processor which is translated internally from "M" into the binary equivalent of the number 77, or 01001101. In those terms, the letter is usable as pulses of electricity racing through a microprocessor's various parts.

the other bebfits of the brain mouse is that it is wireless in its modern form provided by the
advanced brain mouse providers they all provide it with best softwares ever made for all of us
