computer

A computer is a machine that accepts data as input, processes that data using programs, and outputs the processed data as information. Many computers can store and retrieve information using hard drives. Computers can be connected together to form networks, allowing connected computers to communicate with each other.
  • The two principal characteristics of a computer are: It responds to a specific instruction set in a well-defined manner and it can execute a prerecorded list of instructions call a program. There are four main processing steps in a computer: inputting, storage, outing and processing.
    Modern computers can do billions of calculations in a second. Being able to calculate many times per second allows modern computers to multitask, which means they can do many different tasks at the same time. Computers do many different jobs where automaction is useful. Some examples are controlling trafic lights,vehical computers, security systems, washingmashine and digital televisions.Most humans have a problem with math. To show this, try doing 584 × 3,220 in your head. It is hard to remember all the steps! People made tools to help them remember where they were in a math problem. The other problem people have is that they have to do the same problem over and over and over again. A casher had to make change every day in her head or with a piece of paper. That took a lot of time and made mistakes. So, people made calculator
     that did those same things over and over. This part of computer history is called the "history of automated calculation," which is a fancy phrase for "the history of machines that make it easy for me to do this same math problem over and over without making mistakes."

when somebody lost is happiness?

Sit in a quiet place and consciously think about optimistic future goals or happy memories. Make a list of five great moments from your past and five future events you're psyched about. Envision as much detail as you can.Find the things that make you happy. If you're stuck in a job you hate, but you have to stay (even just for a little), start doing things after work that make you look forward to waking up. Work out, make art, start a blog (or read some inspiring quotes)! Do what makes YOU happy, because you can't run from yourself  When going through tough times, it's easy to sit around wondering: "Why didn’t I?” “Why did I?” “What if?” “Why me?” “Why not them?" “What if my  fear  comes true?” These are all time-wasters and downward spiralers, as there are no happy answers.
