What company created the Winchester computer drive?
In 1973, IBM developed the Winchester computer drive
What did the very first computer look like?
The screen was very bad and it was much heavier and bigger than computers today. They took up entire rooms and a hard disk for 5 megs was ans wide as your arms are long (this is 80s military tech). They also had what look like giant casset players (as tall as you are wider then your arm span). This was used to play the previous version of the floppy, which was a long magnetic tape, just like VHS and tapes.
Importance of computer in hospital?
Biotechnology That is the correct name but does not explain what. Electronics are used in medicine to supply many functions to help us survive. Artificial heart for one or heart stimulus to control the rate of beating of the heart.
What is Computers to which other computers connect called?
A Server
Depends on the network topology (design). Is the topology a token-ring, star, bus, etc? Server is usually the correct answer in general, but you also have switches, routers, and on older networks, hubs. Some old networks didn't use servers at all. All of the computers combined made up the "server" so to speak as they were all directly linked to one another such as in a bus topology. The problem with bus is that if on computer goes down, the entire network goes down.
When was the first apple mac laptop invented?
Interesting Facts:
Though often thought of as the first mac laptop, The "Mac Portable" (released in 1989) was not the first mobile computer with a Mac OS. The "DynaMac" released in 1987 used a Mac Plus ROM in a laptop case. The $4,000 to $8,000, 18 to 24 pound laptops were a repackaged Mac Plus or SE with a 9" 640x400 backlit amber electroluminescent or gas plasma screen. Dynamic acted as an official Value Added Reseller for Apple. Like other laptops of the day, there was no integrated pointing device (none needed for DOS!), so users had to attach an external mouse. So the Mac Portable was rather innovative in that it included a trackball.
How do you explain about computer?
Computer of all sizes have common characteristics - speed, arithmetical and logical operations, accuracy, reliability, storage, retrieving data and programs, automation, versatility, communications, diligence , feelings ,travel and leisure life today. Computers are the foundation of business, travel , and leisure life today. Computer provide the processing speed required by all facets of society. The quick service we expect at the bank, at the grocery store, on the stock exchange, and on the stock exchange ,and on the Internet are dependent on the speed of computer.
What is the mission statement of CISCO?
Cisco ... enables people to make powerful connections - whether in business, education, philanthropy, or creativity. Cisco hardware, software, and service offerings are used to create the Internet solutions that make networks possible-providing easy access to information anywhere, at any time."

I'm pretty sure it doesn't i think it says bu I'm not sure and my friends said it wont
Rubies are a nonconducting gem stone. Almost all crystals, stones and gemstones are nonconductors, with a few rare exceptions, such as graphite.
Why computer called computer not calculator?
A calculator requires that a human tell it each operation step by step as the problem is being solved, every time a problem is being solved.
A computer performs the steps needed to solve the problem automatically without human supervision, once those steps had been specified (i.e. computer program) by humans.
Babbage designed 3 machines but built none:
- Difference Engine - This was a machine for calculating polynomial functions by the "method of differences". He had a government contract to design and build a prototype, but he got diverted by ideas for a better machine (Analytical Engine) that could solve a much wider range of problems also he argued repeatedly with his machinist delaying parts. Eventually parliament canceled the contract for nonfulfillment and the project died.
- Analytical Engine - This was an actual general purpose programable digital mechanical computer, but without funding it couldn't be built.
- Difference Engine II - This was a redesigned Difference Engine using concepts from the Analytical Engine, the parts count was reduced by over a factor of 6 thus reducing the cost by a similar factor but with the same calculation ability as the original Difference Engine. Babbage tried to convince the government to fund this, but parliament decided they had wasted enough money on this crackpot already, and without funding it couldn't be built.
Two copies of Difference Engine II have been built by the London Science Museum, to prove that the machine could be built to 1840's machining tolerances and work (a long debated point). Both work as designed computing correct answers. However the machines have a tendency to break difficult to replace parts, so the museums tend to select simple problems to solve that avoid using known broken parts instead of replacing them.
universal automatic computer
Means UNI VAC IDEA OF JON VON NEUMANN..
How did chales Babbage get the idea to invent the computer?
he got frustrated being a human computer, with human computer error rates, with typesetting errors of human computers hand written answers, and said "there has to be a way to do this with steam!"
How did the computer change the world?
It changed the world because you didn't have to use computer art the libray anymore you can just use the one that you got .Also for the people that was born in the times that it was invented could have something to do there work on. and it had to do with the making of a great way to find out things on the internet and i must tell all people that the internet is a great thing to use in the furture and it will be inproved
When was multimedia first used in the world?
The first use as a adjective was in 1962, several sources, including the including Merriam Webster
Webster says, the first use as a noun (multimedia as in 'combining several kinds of media') was in 1950.
Wikipedia says the term was coined in 1966
In technology (printers, etc), Hewlett Packard.
In food (HP Sauce, etc) Harry Palmer - the founder. (Not "Houses of Parliament", despite an image of the Parliament being on the label of every sauce bottle).
The acronym HP can also be an abbreviation for "horsepower" (a unit of mechanical work equal to 746 watts).
Did lady Augusta lovelace create the computer?
She assisted Charles Babbage by writing programs for his computational engine and as such she is attributed with being the first ever programmer. In honour of this a programming language was named after her 'Ada'.
Why an understanding of the binary number system is important to IT professionals?
Computers do most of their calculations in binary, internally.
The binary system consists of 1's and 0's only, which are used in computer technology to signify "on" or"off", the only possible states for each of the millions of transistors operating the machine.
What was the memory capacity of second generation of computer?
8 gb hard drive running win98 and 32 MB ram,WOW! 3 grand for that what a ripoff lol
