What are 3 elements of computer system and their examples?
Basic Computer Elements: In generally used computers one can find that there are four basic computer elements following are the elements.
(1) ALU (Arithmetic Logic Unit): The ALU is the digital circuit that is able to perform different types of functions, such as Addition, Subtraction, and Multiplication etc.
(2) Control Unit: The control unit is the part of CPU (central processing unit) or other devices that performs the duty to direct its operations, the control unit is just like a finite state machine that has some finite states and the transaction from one state to the other state is called action.
(3) Memory: The memory is another very important element of the computer without memory the computer can't operate in today's modern age it is called the RAM (Random Access Memory) when ever we give some instruction to the computer it passes through RAM to the Processor and the processor processes it and send it back. The main reason behind memory is that it is faster in communication with the processor then the other memory devices such as hard disk etc.
(4) Input/output devices: The input and output devices is another important element for example the processor is the input device and it gives its output to the monitor etc for output.
There is another very important point the basic elements are considered as CPU (central Processing Unit), I/O devices, and Memory actually the CPU is the composition of different other elements such as ALU, Control Unit, Registers which is another type of memory.
Who created the first commercially successful telegraph?
The wireless telegraph was invented by Thomas Edison.
Who invented the first recorded mechanical calculator?

What is the typical size of magnetic tape?
Magnetic backup tapes, like the audio tapes they were developed from, range in size from tiny cartridges with tape 1/8" wide all the way up to gigantic open reels several feet wide, containing 2" or wider tape.
There are actually two individuals who played a large part in building the first computer chip. Their names are Jack Kilby and Robert Noyce.

How are gears connected by a chain is on a bicycle?
Just fine, thank you for asking.
The chain transfer power from where it's generated by the pedals to the rear wheel where it can push the bike forward.
The gears on a bike work just like any other set of gears, they allow you to trade power for travel - or the other way around. If spinning the pedals is too easy and you can't crank them round any faster, then a change of gears will make the rear wheel turn more WRT the pedals than before, bringing more resistance to the pedals and more speed to the bike. If turning the pedals is too heavy, then dropping a gear will make the pedals easier to turn on the cost of the rear wheel spinning a bit less for each turn of the pedals
What are computers and name some types of computers?
Computers are device by which we can play games, watch movie, chat, work, etc. It is very useful to human beings as we made It for our own purpose.
Some types of computers are :-
1) Micro computers
2) Mini computers
3) Super Computers
4) Laptop (not exactly computer but is seems like and works like )
Thanks You for your Question!
Why was Apple Inc named Apple?
The history about the name of Apple Inc. is Steve gave his team members one day's time to think about a good name of his company otherwise he will put the company name A for Apple. He got many names at the end of the day but didn't like any one. So next day he named his company Apple.
There are various stories as to why the Apple name was adopted. Some say that it was just a name that did not sound like a techno geeky computer name. Steve Jobs has said that he was on a fruit only diet and declared that if no one came up with a better name he would call the company Apple. No one came up with a better name so it became Apple. Steve Jobs could not call it Apple because The Beatles already had the brand name Apple on there records, and the business name as well. It was taken to the high court in London and Steve jobs liked the name Apple as well as The Beatles. It was settled and Steve Jobs paid 26.5 million dollars to the Beatles company. It did not stop there he had further brushes with The Beatles company about iTunes.
What was sold first sony walkman post it notes or Macintosh computer?
The answer is Sony Walkman in 1979.
Post it - 1980's
Mcintosh - 1984
P.S.
Technically, the Post It Note was first launched in stores in 1977. They failed because nobody knew what they were, however they were still the first item of the three to be launched in stores.
Use of vacuum tube in first generation of computer?
It's purpose was to act like an amplifier and a switch. Without any moving parts, vacuum tubes could take very weak signals and make the signal stronger (amplify it). Vacuum tubes could also stop and start the flow of electricity instantly (switch). These two properties made the ENIAC computer possible.
Who invented the mainframe computer and when was it invented?
Thomas Flowers of the british post office in 1942. It was called Colossus and was used to crack the German high command's cyphers.
When was the first computer offered to the public?
I believe that International Business Machines built the first computers for sale, and they were basically built according the the customers requirements. Other companies followed suit, such as Burroughs. It was not until IBM introduced the 360 model that a standardized computer was offered for sale.
The first commercial computer in the US (sold in quantity more than one and designed to the manufacturer's specification, not the customer's) was made by Remington Rand beginning in 1951, it was the UNIVAC I. IBM followed in 1952 with its 701.
IBM's 709, 7090, 7094, and 7094 II scientific computer line and 705 I, 705 II, 705 III, and 7080 business computer line; long predated the 360 family as standardized compatible computers. The main thing the 360 family did in 1964 was produce a unified scientific/business computer architecture covering a wide range of implementation and price/performance options, making it attractive to a wider customer base.
What is a second generation computer?
Most systems of classifying computers define the second generation computers to be those built with discrete transistors (no vacuum tubes, no integrated circuits). This spans roughly ~1958 to ~1964.
Short note on generations of computers?
a lots of research is going on for the fifth generation computers . the major shortcoming in the earlier generation was lack of thinking power . the fifth generation computer system project was initiated by japan 's ministry of international trade and industry begin in 1982 .
What is the first computer programming software?
The first computer program is thought to have been created by Ada Lovelace in the 1840's for Charles Babbage's general purpose computer. The program was called Notes and it was an algorithm that was to be used by a computer.
How big was the first working computer?
first generation computers varied in size from about the size of an office desk to occupying an entire floor of a large concrete building in hundreds of racks.
What was the very first computer virus written in 1981 called?
The first computer virus ever invented was the Creeper virus. The Creeper virus was invented in 1971 by Bob Thomas. The Creeper virus was highly experimental and it was accidentally released. It infected dozens of machines (because back then there wasn't that many computers). A group of people realized the potential danger the Creeper virus showed, so they created a counter-program called Reaper in order to find and remove the Creeper virus from infected machines. The Reaper program spread like a computer virus, but it deleted itself once it found no more infected machines.
How did the first people use phones?
Alexander graham bell used his invention, the telephone, to call his assistant over across the street. they were both surprised that they could hear each other through the phone.
How did Charles Babbage help the world today?
it helps people makes life and assignment becomes faster and easier because of internet
