This section applies to most common RAM machine-based computers.
In most cases, computer instructions are simple: add one number to another, move some data from one location to another, send a message to some external device, etc. These instructions are read from the computer's memory and are generally carried out (executed) in the order they were given. However, there are usually specialized instructions to tell the computer to jump ahead or backwards to some other place in the program and to carry on executing from there. These are called "jump" instructions (or branches). Furthermore, jump instructions may be made to happen conditionally so that different sequences of instructions may be used depending on the result of some previous calculation or some external event. Many computers directly support subroutines by providing a type of jump that "remembers" the location it jumped from and another instruction to return to the instruction following that jump instruction.
Program execution might be likened to reading a book. While a person will normally read each word and line in sequence, they may at times jump back to an earlier place in the text or skip sections that are not of interest. Similarly, a computer may sometimes go back and repeat the instructions in some section of the program over and over again until some internal condition is met. This is called the flow of control within the program and it is what allows the computer to perform tasks repeatedly without human intervention.
Comparatively, a person using a pocket calculator can perform a basic arithmetic operation such as adding two numbers with just a few button presses. But to add together all of the numbers from 1 to 1,000 would take thousands of button presses and a lot of time, with a near certainty of making a mistake. On the other hand, a computer may be programmed to do this with just a few simple instructions. For example:
mov No. 0, sum ; set sum to 0 mov No. 1, num ; set num to 1 loop: add num, sum ; add num to sum add No. 1, num ; add 1 to num cmp num, #1000 ; compare num to 1000 ble loop ; if num <= 1000, go back to 'loop' halt ; end of program. stop running
The largest difference between any laptop computer and desktop computer is that a laptop is portable and a desktop is not. If you do not require you computer to be portable then a desktop computer is preferable as it will be cheaper to purchase than a laptop of equal specs.
It's a matter of choice. If you like flexibility laptop will be better for you. If you do not mind to have your computer at the same place desktop will work for you.
A laptop offers the portability that a desktop computer does not. You can take a laptop with you on flights and on travel trips while you cannot bring a desktop computer.
the desktop is the thing that you see when you start your laptop with the icons etc. the laptop is the computer (portable)
laptop have fast speed this is wrong answer plz give me the answer og this qyesion plzz
It depends on the person. A laptop would be good for college because you can take it around with you. A desktop is standard and if you need something to do at school. You would have to use the school desktop computers.
Desktop computer
The main screen of laptop where you can see icons like my computer, my documents is desktop
if your going to go somewhere to practice sometimes laptop, but if your only practicing in 1 place (like your room or something) then a desktop.
It is called a laptop because a desktop is a computer that goes on a desk where as a laptop is a computer that goes on someones lap.
at the back of the laptops is a cooling fan, it is not as powerful as the desktop computers but if is sufficent if you play games on the laptop it might over heat there for it would be better to play games on a desktop computer!!
A desktop is larger and sits on a desk. A laptop is smaller and portable; you can carry it with you.
