These parts are interconnected by busses, often made of groups of wires.</p> <p>The control unit, ALU, registers, and basic I/O (and often other hardware closely linked with these) are collectively known as a central processing unit (CPU). Early CPUs were composed of many separate components but since the mid-1970s CPUs have typically been constructed on a single integrated circuit called a microprocessor.</p><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4518034560091080470-6725152647933644857?l=computertoyou.blogspot.com' alt='' /></div>Kustianahttp://www.blogger.com/profile/08627780539646453815noreply@blogger.com0tag:blogger.com,1999:blog-4518034560091080470.post-33043517976307211082007-08-21T02:55:00.000-07:002007-08-21T03:32:22.506-07:00<p>A <b>computer</b> is a machine for manipulating and processing data according to a list of instructions.</p> <p>Computers take many physical forms. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers (and were nowhere near as advanced). Today, computers can be made small enough to fit into a wrist watch and be powered from a watch battery. Society has come to recognize personal computers and their portable equivalent, the laptop computer, as icons of the information age; they are what most people think of as "a computer". However, the most common form of computer in use today is by far the embedded computer. Embedded computers are small, simple devices that are often used to control other devices—for example, they may be found in machines ranging from fighter aircraft to industrial otomotifs, robots, digital cameras, and even children's toys . <br /></p> <p>The ability to store and execute programs makes computers extremely versatile and distinguishes them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: Any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, computers with capability and complexity ranging from that of a personal digital assistant to a supercomputer are all able to perform the same computational tasks as long as time and storage capacity are not considerations.</p> <div class="thumb tright"> </div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4518034560091080470-3304351797630721108?l=computertoyou.blogspot.com' alt='' /></div>Kustianahttp://www.blogger.com/profile/08627780539646453815noreply@blogger.com0
