The first computers were created in the early 1800s. They were called mechanical calculators, and they could only be used by mathematicians and scientists. In 1876, Charles Babbage designed a machine called the Analytical Engine, which could be programmed to perform any calculation that could be done by hand. However, the machine was never completed.
In 1937, John Atanasoff and Clifford Berry developed the first electronic computer, called the Atanasoff-Berry Computer (ABC). However, this machine was not actually built until 1973. In 1941, Konrad Zuse designed and built the first programmable computer.
In 1941, John Mauchly and J. Presper Eckert developed the first electronic computer that could be used for general purposes. This machine was called the ENIAC (Electronic Numerical Integrator and Computer). It could perform up to 5,000 calculations per second.
In 1948, William Shockley, John Bardeen, and Walter Brattain developed the transistor, which made computers smaller and faster. In 1957, Jack Kilby developed the integrated circuit, which made computers even smaller.
In 1971, Intel released the first microprocessor, which made computers even smaller and faster. In 1981, IBM released the first personal computer, which allowed individuals to use computers at home.
Today, computers are used in almost every aspect of our lives. They are used to communicate with others, to do our banking, to shop, to learn, and to work.

How was the computer originally invented?
In 1876, an American inventor named Charles Babbage designed and began building a machine he called the Analytical Engine. The Analytical Engine was intended to be a mechanical computer that could perform any calculation that could be done by hand. However, Babbage never completed the machine, and it was not actually built until 1991.
In 1937, an American mathematician named John Atanasoff and a graduate student named Clifford Berry developed the first electronic computer, called the Atanasoff-Berry Computer (ABC). However, their work was not recognized until 1973, when it was finally proved that the ABC was the first electronic computer.
In 1941, an English mathematician named Konrad Zuse designed and built the first programmable computer, called the Z3. The Z3 was not actually completed until 1941, but it was the first computer to be able to be programmed to perform a specific task.
In 1943, an American mathematician named John Von Neumann designed the first computer that used a program stored in memory, called the Von Neumann architecture. This design is still used in most modern computers.
In 1945, an American scientist named John Mauchly designed the first electronic computer, called the ENIAC. The ENIAC was completed in 1946 and was the first computer to use transistors.
Why was the first computer invented?
The first computer was invented because of a need for a more efficient way to calculate and store information. In 1822, Charles Babbage designed a machine called the Analytical Engine, which could store and calculate numbers. However, the machine was never completed. In 1937, John Atanasoff and Clifford Berry designed the first electronic computer, called the Atanasoff-Berry Computer. However, this machine was not actually built until 1973.
What is the brief history of computer?
The brief history of computer is a timeline that shows the progression of computers from the first computers to the modern computers.
The first computers were created in the early 1800s. These computers were large, expensive, and used for scientific purposes. In 1876, Charles Babbage designed the first programmable computer, but it was never completed. In 1937, Konrad Zuse created the first computer that could be operated with a program.
In 1941, John Atanasoff and Clifford Berry developed the first electronic computer. However, this computer was not actually built until 1973. In 1945, John von Neumann designed the first computer that could store and use programs. In 1948, the first computer was created that could be used by the general public.
In 1950, the first computers were made that could be used for business purposes. In 1971, the first microprocessor was created. In 1981, the first personal computer was created. In 1993, the first smartphone was created. In 2007, the first tablet was created.
The modern computer has come a long way from the first computers that were created in the early 1800s. The modern computer is smaller, faster, and more efficient than the early computers.
What was used before computers?
What was used before computers?
The answer to this question can be a little difficult to define, as there are a number of devices and tools that could be considered before the modern computer. One of the earliest devices that could be considered a predecessor to the computer was the abacus, which was a tool used for mathematical calculations. Other early devices that could be classified as precursors to the computer include the slide rule, the mechanical calculator, and the ENIAC machine.
The abacus is a tool that has been used for centuries, and it is believed to have originated in Babylonia. The abacus is a simple device that consists of a frame with a number of beads or balls that can be moved along the frame. The abacus is still used in some parts of the world today, and it can be used to perform basic mathematical operations.
The slide rule was a tool that was invented in the 17th century, and it was used to help perform mathematical calculations. The slide rule consists of a rule with a number of scales that can be slid along each other. The scales are used to perform different mathematical operations, and the slide rule can be used to calculate a variety of different values.
The mechanical calculator was another early device that could be used to perform mathematical calculations. The mechanical calculator was first invented in the 18th century, and it consisted of a number of gears and levers that could be used to perform calculations. The mechanical calculator was eventually replaced by the electronic calculator, which was first introduced in the 1970s.
The ENIAC machine was the first electronic computer, and it was first introduced in 1946. The ENIAC machine was a large and complex machine, and it was used to perform a variety of mathematical operations. The ENIAC machine was eventually replaced by the modern computer, which was first introduced in the late 1940s.
What is the history of computer in short?
The history of computer is a long and eventful one. In short, computer is a machine that can be used to perform various tasks by following a set of instructions. It can be said that the history of computer can be divided into three parts – pre-computer era, computer era, and post-computer era.
The pre-computer era is the era that predates the invention of computer. It started with the invention of abacus in 2400 BC and ended with the invention of Charles Babbage’s Analytical Engine in 1834. The abacus is a tool that was used to perform mathematical operations by sliding beads on a series of wires. The Analytical Engine was the first mechanical computer that could be programmed to perform any calculation that could be done by hand.
The computer era is the era that started with the invention of digital computer in 1937. It lasted until the early 21st century. In this era, computer became an essential tool for businesses, governments, and individuals. The invention of transistors in 1948 made it possible to build small and affordable computers. The first computers were large, expensive, and used vacuum tubes. However, with the invention of transistors, computer became smaller, faster, and more reliable.
The post-computer era is the era that started in the early 21st century. In this era, computer is becoming more and more embedded into everyday objects. The most famous example of this is the iPhone, which is a computer that is also a phone. With the advent of cloud computing, computer is also becoming more and more accessible from anywhere in the world.
What is computer full explanation?
A computer is a programmable machine that can store, retrieve, and process data.
The two most common types of computers are personal computers (PCs) and servers. PCs are made for individual use, while servers are used in networks to provide services to multiple users.
Computers are made of electronic components, including a central processing unit (CPU), memory, input/output (I/O) devices, and a storage device. The CPU is the brain of the computer and controls all its operations. Memory is used to store data and programs, and I/O devices allow the computer to communicate with the user and other devices. The storage device is used to store data and programs permanently or temporarily.
Computers use a variety of input and output devices, including a keyboard, mouse, touchpad, trackball, joystick, scanner, digital camera, microphone, and printer.
Computer processors come in a variety of sizes and speeds. The speed of a processor is measured in gigahertz (GHz) or megahertz (MHz). A gigahertz is one billion hertz, and a megahertz is one million hertz.

How do you make a computer?
Making a computer is a process that can be done in a variety of ways, depending on the components that are used.
The most basic way to make a computer is to start with a motherboard, add a CPU, and then add RAM. The CPU and RAM can be plugged into the motherboard in a variety of ways, depending on the type of motherboard and CPU. The CPU and RAM can also be plugged into a power supply, which can be plugged into an outlet.
After the motherboard, CPU, and RAM are in place, a storage device can be added. This can be a hard drive, a solid state drive, or a flash drive. The storage device can be plugged into the motherboard or into a separate drive controller.
After the storage device is in place, a graphics card can be added. This can be a separate card or it can be integrated into the motherboard. The graphics card plugs into the motherboard or the drive controller.
Next, a case can be added. The case contains the internal components of the computer and provides a place to attach the external components, such as the keyboard, mouse, and monitor.
The computer can be finished by adding an operating system and any other desired software.
