DEVELOPMENT OF COMPUTERSThe first generation of computers, dating back to 1945, was relatively large and very expensive due to the technology available to us at the time. Called “Colossus,” it was the very first electronic computer developed. These are programmable, digital, electronic computing devices. Vacuum tubes or called thermionic valves are used to perform calculations. It is used to solve the mathematical problem encountered by the British army during World War II. Colossus is used to decrypt secret messages from German messages during World War II. However, Colossus' existence remained secret until decades after the war. The first generation of computers was primarily used by the military, they are not commercially available for use by citizens. In 1946 the first ENIAC (Electronic Numerical Integrator and Computer) was fully built, development began in 1943 which took the developer ENIAC. team took 3 to 4 years to build it. 2 people designed this computer, namely John Mauchly and J. Presper Eckert from the United States. Much like the Colossus, ENIAC took a long time in space. This took up up to 170 square meters of space, which is equivalent to a large room. Thousands of vacuum tubes, diodes, relays, resistors, capacitors and a million solder joints are used to program ENIAC. The ENIAC weighs up to around 30 tonnes and consumes a large amount of energy, around 150 kW. This is not practical because vacuum tubes often break and need to be replaced. Finding the broken vacuum tubes is not an easy task to do, so it takes more time, hours, days and even weeks to program it properly. The ENIAC serves as a device to print shooting tables for...... middle of paper ......computer with the intention of promoting computing worldwide. It can be easily accessible to everyone to develop a program or anything that will contribute to the development of computers. For fifth generation computers, which are currently under development with the aim of developing a device capable of responding to natural language input, capable of learning, but also of self-organization. This can be considered a development of artificial intelligence. Even though the technology is developing, some applications are still widely used today, such as voice recognition. Fifth generation computers will be based on quantum, molecular and nanotechnology computing. This will significantly change the face of computers we see in the future. It appears that fifth generation computers will match the power of human intelligence..
