Who is considered the father of computers?
Atanasio Echeverria y Topete, a Spanish army captain and engineer, is considered the father of computers. In 1842, he designed and built what is believed to be the world’s first programmable computer. The machine was able to execute basic arithmetic operations using metal balls rolling down tracks on its front panel.

What was the first computer?
The first computer was created in 1945 by John Vincent Atanasoff and Clifford Berry. The machine was called the Atanasoff-Berry Computer (ABC) and it used vacuum tubes to perform its calculations.
How has computer technology changed over the years?
computer technology has changed a lot over the years. here is a timeline of some notable changes:
1971- first microprocessor, the intel 4004
1981- IBM introduced its first personal computer, the ibm 5150
1985- windows 1.0 was released
1995- internet explorer became the dominant web browser
2000- google was founded
2004- facebook was founded
What are some of the most significant moments in computer history?
In 1876, the first computer was built. It was called Charles Babbage’s Analytical Engine and could only be programmed by actually altering its hardware.
In 1937, John Atanasoff and Clifford Berry built the world’s first electronic digital computer, which used vacuum tubes.
In 1941, Konrad Zuse designed and built a programmable electromechanical relay-based computer.
In 1945, John Presper Eckert and John William Mauchly build ENIAC (Electronic Numerical Integrator And Computer), the world’s first general-purpose electronic computer.
ENIAC could solve up to 5 equations simultaneously at 1000 words per minute with results that were accurate to around 5 decimal places. It consisted of over 18000 individual parts including 10 000 vacuum tubes!
In 1948, Maurice Wilkes developed EDSAC (Electronic Delay Storage Automatic Calculator), the world’s first stored program machine – programs were literally entered on punch cards). 1951 saw Alan Turing publish “Computing Machinery and Intelligence” – one of the most important papers in computing history as it introduced the concept of artificial intelligence. In it he proposed what is now known as The Turing Test – a test to determine whether or not a machine can be said to think like humans do.
Why do we call them personal computers?
A personal computer is a desktop or laptop computer that belongs to an individual. The first computers were large, expensive and used by institutions such as governments, universities and businesses. Personal computing became possible with the invention of the microprocessor in 1971 by Intel co-founder Gordon Moore. The microprocessor allowed for more powerful and affordable computersand led to the development of the IBM Personal Computer (PC) in 1981. With its introduction, average people could own their own computer for home use at an affordable price point
The term “personal computer” quickly caught on, as it aptly described these new machines that were smaller than earlier models and catered to a single person’s needs. In contrast, mainframe computers were designed for group usage, while minicomputers could be used by individuals but typically had more limited applications than PCs did. Early personal computers ran dos operating systems which worked best when connected to a keyboard, monitor and printer all at once – hence why they’re often called ‘clunky’.
With further advancements in technology came better graphics capabilities, user-friendly interfaces and ever-smaller sizes; so much so that today we carry our entire personal computing experience around in our pockets! From toddlers learning how to swipe left on their parents’ smartphones to seventy-year olds using iPads like they’ve been doing it forever – everyone can benefit from some form of personal computing device in their lives
