Vaccum tubes were the main/basic components  used for memory and circuitry for CPU.
The first generation computers used vaccum tubes for circuitry and magnetic drums for memory.

These components were enormous,taking up entire rooms.
Vaccum tubes were electronic component.

Lee DeForest has founded the vaccum tubes it and valued are used in first generation computers. Vaccum tube is an electronic device that controls the flow of electrons in a vacuum. It used as a switch, amplifier, or display screen in many older model radios, televisions, computers, etc.

First generation computers used vacuum tubes, magnetic drums, and punch cards as their main components. They also used switches and relays for input and output, and used electromechanical calculators for data processing. These computers were large and expensive, and required a lot of maintenance and repair due to the use of vacuum tubes, which were prone to failure. They also generated a lot of heat and consumed a large amount of electricity. Despite these limitations, first generation computers were able to perform simple calculations and logical operations, and played a crucial role in the development of modern computing technology.

First generation computers, which were developed in the 1940s and 1950s, used a variety of technologies that are quite different from those used in modern computers. Some of the main components of first-generation computers included: 

  1. Vacuum tubes: These were used to amplify and switch electronic signals and were the main component of first-generation computers. 
  2. Magnetic drums: These were used as a form of memory, storing data and instructions for the computer to use. Punched cards: These were used to input data and instructions into the computer. 
  3. Teletype machines: These were used as a way to input and output data, allowing users to communicate with the computer through a keyboard and printer. 
  4. Paper tape: This was another form of input and output, used to store and transmit data. 


Overall, first generation computers were much larger and less powerful than modern computers, and they used a variety of mechanical and electromechanical components in addition to vacuum tubes. They were also much slower and less efficient than modern computers, and they required a lot of maintenance.

Main electronic component – vacuum tube Main memory – magnetic drums and magnetic tapes Programming language – machine language Power – consume a lot of electricity and generate a lot of heat. Speed and size – very slow and very large in size (often taking up entire room).

The computers of first generation used vacuum tubes as the basic components for memory and circuitry for CPU.

These tubes like electric bulbs, produced a lot of heat and the installations used to fuse frequently.

First-generation computers, which emerged during the late 1940s and early 1950s, used vacuum tube technology as their primary electronic component. These computers were massive in size, consumed significant amounts of power, and produced a considerable amount of heat. Here are the key components used in first-generation computers:

Vacuum Tubes: Vacuum tubes, also known as thermionic valves, were used as electronic switches and amplifiers in early computers. They were large, fragile glass tubes that controlled the flow of electrons. Vacuum tubes generated a significant amount of heat and were prone to failure, leading to frequent maintenance and cooling requirements.

Magnetic Drum Memory: Early computers used magnetic drum memory for data storage. Magnetic drums were large metal cylinders coated with a magnetic material. Data was stored and accessed by magnetizing specific areas on the drum's surface. However, magnetic drums had limited storage capacity and slower access times compared to modern storage technologies.
