What was IBM’s first computer and when did it come out?
IBM’s own Personal Computer (IBM 5150) was introduced in August 1981, only a year after corporate executives gave the go-ahead to Bill Lowe, the lab director in the company’s Boca Raton, Fla., facilities. He set up a task force that developed the proposal for the first IBM PC.
How much did the first personal computer cost?
IBM priced its initial IBM PC at $1,565, and that was a relatively steep price in those days, worth about $5,000 today, give or take a few hundred dollars. In the US in 1981 that was about the cost of a decent used car.
What did Bill Gates invent?
In 1975 Gates, then a sophomore at Harvard University in Boston, Massachusetts, joined Allen, who was working as a programmer for Honeywell near Boston, to write software for the first microcomputers, later called PCs. They started by adapting BASIC, a popular programming language for large computers.
What are the 7 types of computers?

Who invented the PC?
Henry Edward Roberts, designer of the Altair 8800 Computer, “deserves credit as the inventor of the personal computer,” Cerruzi asserts. “Although calling Roberts the inventor makes sense only in the context of all that came before him . . . he does deserve the credit.” C’mon IBM, have a heart.
Why did IBM fail?
A Failure at Fundamentals. In the 1980s, IBM’s profit margins suffered a steep decline. For example, the decline of profit margins was a result of falling customer interest in mainframe computers. That IBM executives failed to foresee this was the result of two more basic factors.
What happened to IBM computers?

What is the most expensive computer?
Here are the most expensive gaming computers ever built
- 8Pack OrionX – $30,000.
- Yoyotech XDNA Aurum 24K – $13,000.
- Kylaralthor Janus 2.0 – $18,000.
What did Apple do first?
Apple’s first product, the Apple I, invented by Apple co-founder Steve Wozniak, was sold as an assembled circuit board and lacked basic features such as a keyboard, monitor, and case.
How much does it cost to run Computer 24 7?
Electricity ranges from about 10 cents per KWH to 20 cents in the US. So the laptop on 24/7 would cost $32.40 at 10 cents and $64.80 per year at 20 cents. The desktop on 100% full power 24/7 would cost about $193 to $386.
