Who built the world's first binary digit computer the Z1?
Konrad Zuse of Berlin. The Z1 was first designed in 1934 and completed in 1938. It was destroyed by Allied bombing raids in 1943 along with all construction plans. However, Zuse reconstructed the original Z1 from 1986 to 1989. It now resides in the German Museum of Technology in Berlin.
Clear History
Generation of modern computer?
Modern computers currently in use today typically belong to the fourth generation of computers which was marked by the introduction of the microprocessor. There are some instances of fifth generation computers in use today, but for the most part this generation is still in the research phase.
A system is a group of independent but interrelated elements comprising a unified whole.
Transistors placed in computers?
The transistor was originally used in computers to replace the vacuum tube.
The function of the vacuum tubes was to regulate the flow of energy throughout the computer in order to answer a function.
Transistors are semiconductors that are most commonly embedded in Central Processing Unit (CPU) chips. These "electric flow regulators" act as microswitches to help the computer "think."
WHAT IS A level certificate in doeacc?
I am a Bikas Chandra Maity. I lost my all paper clearance marksheet. How am I collect duplicate marksheet?
Google translator states it as "ávakas" - pronounced a-va-cas"
What does unexplained phenomenon mean?
An unexplained phenomenon is a thing that someone or a group of people saw. It is unexplained when their is no logical reason as to why it happened. UFO's serve as examples to unexplained phenomenons.
What does Moore's law predict?
Moore's Law is not a law of physics, but is a mere trend identified by the IC engineer Gordon Moore in 1965. It predicts, or more accurately states that the number of transistors that can be placed inexpensively on an integrated circuit doubles approximately every two years.
No, HAL is a fictitious computer that appears in the Arthur C. Clark book and Stanley Kubrick movie 2001 a Space Odyssey. No such machine exists nor is one likely to ever exist.
What are the uses and different types of monitors?
There are two main types of monitors - TN and IPS.
There are also different sizes and aspect ratios of monitors too.
TN displays - what most monitors are. These types of monitors usually have poorer colour rendition and poorer viewing angles that IPS monitors, but they can have much higher refresh rates (100 hz, 120hz, 144hz etc) and their input lag is usually very low (1ms response time). These are best used for gaming as you need fast response times and refresh rates. They are usually cheaper that IPS displays.
IPS displays - more suited to those that are wanting to watch films in high definition, edit photos/videos or just enjoy the colour rendition a bit more than would be yielded with a TN display. IPS monitors tend to have normal refresh rates (60hz) and have usually higher input lag (5ms +) but their colours are MUCH better than TN monitors are are really fantastic for that. They also have much larger viewing angles ( up to 179 degrees). These are usually more expensive.
There are diferent sizes of monitors too, the two main options being 24" and 27". The sizing depends on what you want it for, but performance wise they are largely similar. 24" monitors are the most popular
One more point is the aspect ratio and resolution of the monitor. Most 24" monitors have an aspect ratio of 16:9, and a resolution of 1920x1080 pixels. These can vary (such as 16:10 aspect ratio monitors and 21:9) but it is personal preference. You can get 4K displays too, though these are very expensive currently.
