History of computer

Computer tech study:- History of computer
It was difficult for humans to calculate from the start. Humans can only calculate or calculate to a limited extent without machines. In order to be able to perform many calculations, humans have to rely on the machine to meet this need. Built computers, that is, to calculate.

Abacus - 3000 years ago

Abacus was developed by Chinese scientists about 3,000 years ago. In a rectangular frame were wooden boards on iron bars, which were calculated or calculated from top to bottom. That said, it was the first computer to run without electricity. In fact, it was up to you to do this job.

Antikythera system - 2000 years ago

Antikythera was originally an astronomical calculator used to track solar and lunar eclipses in ancient Greece. Antikythera is approximately 2000 years old and was discovered by scientists in 1901 on a ship that was completely destroyed on the island of Antikythera. Acquired in a chronically dilapidated state, the name Anticythera System has emerged since then. Scientists devoted themselves to decoding and carrying out long studies. This computer was later decoded. This machine shows the position of the planets as well as the sun and moon in the sky. The Antikythera system was credited with being the first known analog computer in modern times. The Greek Antikythera system was developed to correctly estimate astronomical and mathematical data.

Pascaline - 1642

Pascaline was built after Abacus. It was made in 1642 by Blaze Pascal, a math expert, who calculated it faster than Abacus. It was the first mechanical calculator. This machine was called an adding machine, this Blade Pascal adding machine is also called a Pascaline.

Difference engine- 1822

The differential motor was an instrument developed by Sir Charles Babbage that could perform precision calculations that were invented in 1822 and used punch cards to store programs. It used to run with steam, the foundation for computers that are built today. That is why Charles Babbage is called the father of computers.

Juse Z - 3 - 1941

The great scientist "Conard Juice" invented the "Zuse-Z3" salt, an incredible instrument that was the first electronic computer based on binary arithmetic and floating point arithmetic.

ENIAC- 1946

A US military examination room USA He built an "ENIAC" machine, which stands for electronic numerical integrator and computer. "ENIAC" worked on the decimal arithmetic system, later "ENIAC" was initially known as a computer, which later became a modern computer.

Manchester Small Scale Machine (SSEM) - 1948


(SSEM) was the first computer to protect a program in a vacuum tube. The nickname Baby was created by Frederick Williams and Tom Kilburn

computer memory basics

computer memory What is computer memory? The CPU is called the brain of a computer, but while the human brain does a lot of work and protects our memories, the CPU only does arithmetic and logical calculations. Processes input data, process data cannot be protected because process data must now be stored in a safe place so that this task can be performed using computer memory (computer memory). Computer memory is divided into many small parts that we call cells. Each cell has a unique address or path. Whenever you save or save a file on a computer, it is saved in a cell - There are two types of computer memory : Variable - It is also called primary storage, also called primary storage. It is in direct contact with the CPU and its data and instructions are used quickly and directly by the CPU. This is called a variable memory because this memory cannot store any data permanently. Example - RAM Non-volatile - This is known as secondary storage. It is used to permanently stor...

Computer classification based on the working method

Computer classification based on the working method                                 What is an analog computer? This category consists of computers that measure pressure, temperature, length, speed, etc. of the physical units. Let us understand a little more and talk about the pressure of meteorological wind, moisture, or rain in the atmosphere. Or what was the lowest or highest temperature today? Analog computer was developed to collect data of all these rain gauges (rain gauges) at a certain place. The amount of precipitation received is measured, 2 hygrometers - it measures the atmospheric humidity, anemometers - it measures the power and speed of the air, ie all-analog computers collect physical data. What is a digital computer? Digital computers are computers that you normally use at home or in offices, where data is fed in and output digitally. Most digital computers are used and marketed. Di...
