Question

What is computer ? ( high level answer not simple answer )​

Answer 1

A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster.

A broad range of industrial and consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devices like personal computers and mobile devices like smartphones. Computers power the Internet, which links billions of other computers and users.

Early computers were meant to be used only for calculations. Simple manual instruments like the abacus have aided people in doing calculations since ancient times. Early in the Industrial Revolution, some mechanical devices were built to automate long, tedious tasks, such as guiding patterns for looms. More sophisticated electrical machines did specialized analog calculations in the early 20th century. The first digital electronic calculating machines were developed during World War II. The first semiconductor transistors in the late 1940s were followed by the silicon-based MOSFET (MOS transistor) and monolithic integrated circuit chip technologies in the late 1950s, leading to the microprocessor and the microcomputer revolution in the 1970s. The speed, power and versatility of computers have been increasing dramatically ever since then, with transistor counts increasing at a rapid pace (as predicted by Moore's law), leading to the Digital Revolution during the late 20th to early 21st centuries.

Conventionally, a modern computer consists of at least one processing element, typically a central processing unit (CPU) in the form of a microprocessor, along with some type of computer memory, typically semiconductor memory chips. The processing element carries out arithmetic and logical operations, and a sequencing and control unit can change the order of operations in response to stored information. Peripheral devices include input devices (keyboards, mice, joystick, etc.), output devices (monitor screens, printers, etc.), and input/output devices that perform both functions (e.g., the 2000s-era touchscreen). Peripheral devices allow information to be retrieved from an external source and they enable the result of operations to be saved and retrieved.

Answer 2

Answer: A computer is a device that accepts information

Explanation:

There are 3 types of computers

Analogue Computer.

Digital Computer.

Hybrid Computer.

Hybrid computers are computers that exhibit features of analog computers and digital computers. The digital component normally serves as the controller and it provides logical and numerical operation.

What do they do?

Computers have revolutionized the way we live, work, and communicate. With their ability to process vast amounts of data at incredible speeds, computers have changed the face of many industries, from medicine to finance. They have made our lives more efficient and convenient, allowing us to shop, bank, and connect with others online. However, they also come with their own set of risks, such as cyber attacks and addiction. As computers continue to evolve, it is important that we use them responsibly and ethically, and stay vigilant against potential threats.

Computers are electronic devices that can perform various tasks such as processing data, storing and retrieving information, and communication. These machines are made up of several components including the CPU, RAM, motherboard, and storage devices. A computer operates using binary code, which is a series of 1s and 0s. The first computer was invented in the 1940s and was the size of a room. Computers have revolutionized the world and changed the way we communicate, work, and learn. They have also played a critical role in the development of other technological innovations such as smartphones, tablets, and robots.

How are they simular to smartphones?

Phones and computers are similar in many ways. Both are electronic devices that allow users to communicate and connect with others. They both have screens for displaying information, cameras for capturing pictures and videos, and speakers for playing back audio. Both also connect to the internet, enabling users to access a vast amount of information and services. Both devices often have similar operating systems, such as iOS or Android, making them easy to navigate and use. Additionally, both devices can be customized with various apps and software programs to enhance their functionality.

Electronics and electricity have revolutionized the way we live our daily lives. Without them, we would not have access to instant communication, entertainment, or even basic necessities like lighting and heating. Electronics have made significant advancements in recent years, from the miniaturization of devices to the development of cutting-edge technologies like artificial intelligence and blockchain. Electricity powers all of these devices, enabling them to function efficiently and effectively. As we continue to rely more on electronics and electricity, it is important to ensure sustainable and efficient use to mitigate their negative impact on the environment.
