Computers only understand two types of data; binary code and character-based code. Binary code consists only of ones and zeros—which can be meaningful when put together in long, differentiated strings. Character-based code consists of letters, numbers, and symbols that humans recognize as part ...
Some people say that the increasing use of computers and mobile phones for communication has had a negative effect on young people's reading and writing skills. To what extent do you agree or disagree? Give reasons for your answer and include any relevant examples from your own knowledge or ...
How do your computers,cell phones or i-pads remember you?Maybe they get to recognize*you by your secret numbers.Soon computers and other machines like cars will be able to remember you by looking at your eyes.It is the eye-recognition program.The program works because everyone's eyes are ...
Photo: Calculators and computers are very similar, because both work by processing numbers. However, a calculator simply figures out the results of calculations; and that's all it ever does. A computer stores complex sets of instructions called programs and uses them to do much more interesting...
You may be wondering how a computer can actually generate a random number. Where does this "randomness" come from. If it's just a piece of computer code, isn't it possible the numbers the computer generates could be predictable? We generally group the random numbers computers generate into ...
Method 2. Open Numbers File on PC via iCloud It's a good idea to open Numbers via iCloud. All you need to do is login to iCloud and follow the steps below. Step 1.Launch a web browser on our computer and go toiCloud.com. ...
how much ram the machine has. why does this matter and how can you know what numbers you should be looking for? read on, and we will tell you everything you need to know – and it won’t feel random at all. what is ram and what does it do? at a very basic level, a computer...
That is why the range of positive numbers you can store in unsigned integers is larger than signed ones. For example, most computers use a 32-bit architecture these days, so integers will have 32 bits as well in C. This means that an unsigned INT can go up to 4,294,967,296 (which...
Humans work on numbers in decimal format (the numbers 0–9) largely, it's believed, because we have ten fingers and toes to count with. But the numbers we use to write out amounts of things are arbitrary. Let's say you have a pile of coins and you want to tell me how wealthy yo...
