What is computer

computer is a digital electronic machine that can be programmed to carry out sequences of arithmetic or logical operations (computation) automatically. Modern computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. Computers are so advanced in these generations because, we are now developed too much, and now we have a higher technology. In past generations, the computers were not too much developed, they were too big and not were very fast and responsive, the computers were bigger than a large room because there were no technology and not too many developed engineers to make it small. The people only used it for communication and to save and send data but surprisingly in that time, the computers have only near 1 byte storage in the computers, so you can understand now that how much is now technology developed, and it is faster than a sound wave to response the command which is given to the computer. The people in the old time can't even expect that the world can have terabytes in a small chip. The computer is an electronic machine which is divided into two parts called software and hardware. The hardware is that which we can sense and see physically in our real life. The software is that which we can see but can't touch physically. The software is also called an organization system, which have too many names, but these three are popular in the world. The Windows is an operating system made by Microsoft company which is being handled by Bill Gates who is also a billionaire and all know him because he also invented Microsoft apps which we use in our daily life. The second one is called macOS which is made by Apple company which is a rich company known for making the best quality accessories in the world, its MacBook uses the macOS software which is used to control the MacBook, this is also the world's most expensive laptop in the world. These two were the software programs which take too much cost to get its installation CD from the original shop, but the third one Linux is the free one version of software and is also available on Google, so this is more useful than the two others, so I prefer you to get this software on your computer. Now we can talk about laptop and computer companies from which you should buy your computer, first apple this company is a mobile manufacturing company, and it also makes laptops and laptops from this company are too safe and are made up of the best quality material, but it is too expensive. Second the dell company, this company is also like the apple company, but it didn't make mobiles, and it is less expensive than apple. Its material is also good, and it is safer also, so I prefer you this company to buy laptops and computers. I prefer you dell computer. Dell computer is good product .
