This is a video that a student made for a class project. It tells
briefly about the history of computers and where they first started. This video
tells about all the different types of computers and where they first and how
they worked. This is helpful because it tells you how the earlier computers
where designed. This video also tells about the newer computers as well as portable
computers.
This is a picture of the ENIAC. This computer weighed 30
tons was with the dimensions of 8.5 feet by 3 feet by 80 feet and took up about
680 square feet. This computer had 17,468 vacuum tubes, 7,200 crystal diodes,
1,500 relays, 70,000 resistors, 10,000 capacitors and approximately 5,000,000
hand-soldered joints. It could consume 150 kilowatts of electricity when it was
on.
In this video it talks about how Apple and Microsoft were
started. Bill Gates made the first electric calculator and Steve Jobs hacked
cell phones to make long distance calls. Later each of them went on and made
multi-million dollar businesses. Bill Gates was the inventor of Microsoft, the
Xbox, the Xbox 360, and a lot of other useful devices. Steve Jobs was the
Inventor of Apple which produces new devices every year. They have invented the
Ipad, iPod, iMac, and many other devices.
This is a picture of the Apple computer. This is a high-tech computer invented by apple. The speed of the processor or the CPU is measured in Hertz or cycles per second. Similar to the memory, the metric system is used to define the speed of the system. The higher the processing speed, the quicker the computations. The memory is incredible for a small computer like this one.
This is a video of the new Surface by Microsoft. This is a
computer and a tablet in one. The Surface has a detachable key board when you
need it. The Surface has a frontward and rear facing camera. The rear camera is
set at 20 degrees so when you put the kick stand out the camera is looking straight
ahead.
