This computer was the base for all of the current computers, and those that will come after. One huge invention to aid the computer is the CPU, or central processing unit, this is the part people often call the “brain” of the computer. They are wrong, the CPU is not the brain, it is literally the part that does the computing. “Every command you send to your computer — whether it’s a key press, a mouse click or a complicated command line instruction — is converted into binary and sent to the CPU to be dealt with” (Guinness). A CPU has billions of transistors, a transistor is a device that regulates current or voltage flow and acts as a switch or gate for electronic signals.
He invented the first fully operating computer in the early 19th century. (wikipedia.com) A computer can be defined as “an electronic machine which helps in solving problems quickly and easily. It solves problems according to the instruction given to it. It is also a digital machine used in all fields” (wikipedia.com) this is the working definition of a computer. Today imagining our world without computer and computer dependent devices is near to impossible.
According to Merriam-Webster dictionary the word Computer means: "an electronic machine that can store and work with large amounts of information". Computers that we use today have undergone many years of evaluation and development. The history of computer development is referred to the five generations, vacuum tubes, transistors, integrated circuits, microprocessors, and finally artificial intelligence computing devices. Moreover, each generation is characterized by a crucial technological development that basically changed the way computers operate. The most essential part in computer is the Operating System that enables us to use the computers.
Computer system consists of any software and various peripheral devices such as a printers, scanners or routers that are necessary to make the computer function. Every computer requires an operating system. The computers that are connected to the system can operate independently. They have the ability of communicating with other external devices and computers. Computer system is a combination of electronic hardware and software.
The evolution of computers have altered our lives a great deal; it affects our government and the way we work and learn. The improvement of computers can be classified into three generations of computers. The first generation of computers (from 1937 to 1946) were built primarily for the military and were only able to perform one task with no operation system. The second generation of computers (from 1947 to 1962) were much improved. They had over 100 different programming languages, they
Under different conditions, it becomes clear which shines brighter as the better alternative to the other. With their introduction in the late 20th century, computers are probably one of the most complex tools known to man. With the ability to perform thousands of tasks every second, they can quickly produce, receive, and access a larger pool of data globally. Since its debut in the 1990s, anything you could ever think of can now be accessed on the portal known as the internet. This in turn made computers highly sought after to enable people access to a worldwide database of information.
In most case an information system also include people. 2. COMPONENT IN COMPUTER-BASED INFORMATION SYSTEM (CBIS) a) Hardware Hardware can be a single PC, a single main frame or networks of computers. It also includes physical device to control the process of input and output like keyboard, mouse and modem. Other than that, hardware resources consist of variety of interconnected peripheral devices.
The Invention of Computers Inventions that changed the world Mohammed Abdulhameed – H00258404 CMG LSC 2103 - Academic Reading and Writing 2 Mr. Napoleon Mannering Word Count: 1179 Computers are one of the biggest inventions that have an impact to our life daily, it helped us in our education fields, entertainments fields and business fields. I have chosen to talk about computers because in the old days we used to have everything written on papers which was difficult for us to do tasks, send messages to other people or even communicate with other people, nowadays in the 21st century it has been made easier with the help of the computers and the internet to communicate globally with different people around the world, the use of computers
Onyemelukwe Dillon A00020911 CIE 111 section 10 Mr. Emmanuel Nicholas November 18, 2017 THE COMPUTER AND ITS ADVANTAGES A computer is defined as an electronic machine that is used for storing, organizing, and finding words, numbers, and pictures, for doing calculations, and for controlling other machines (Meaning of "computer" in the English Dictionary) . The computer has been around for decades, evolving from the room-sized machines they once were into the personal computers we have today. Moreover, through this evolution, the computer has gotten both smarter and more efficient. This has made the computer to have a greater impact on our lives. For instance, the computer has allowed faster and more efficient completion of work.
Computers in Daily Life Computers are becoming significant and indispensable in many distinct areas namely education, business even in daily life. Actually, in the past, the term computer was just a name for the devices which facilitated the process of calculation. Abacus was one of the first computers due to its benefit to calculation, for instance. Computer which first comes to our minds was designed to calculate complex numbers, too. However, it was such a huge device that it could fill a room.
