How did hewlett packard get its name?

it was 2 names and there was a toss to decide which name will come first

Is Everything in a computer binary?

In terms of digital information, most data in a computer is represented using binary, which is a system expressed in zeros and ones. Binary code is used to represent the instructions and data that the computer processes. However, there are also other systems and components in a computer that may not be strictly binary, such as analog signals in input/output devices.

What are examples of RAM?

Some examples of Random Access Memory (RAM) include:

  1. DDR4: A type of RAM commonly used in desktop computers and high-performance laptops.
  2. SDRAM: Synchronous Dynamic RAM, a type of RAM used in older computer systems.
  3. LPDDR4: Low-Power DDR4, a type of RAM commonly used in mobile devices like smartphones and tablets.

Was commodore 64 the first home computer?

No, several machines preceded it; including the Commodore PET, Apple ][, and Atari 400/800.

How long have you been using computers?

I'm certain others will give different answers, but I started using computers in 1973. My current home computer system includes 9 computers, 3 printers, and a tablet; all connected by a combination of ethernet and wi-fi.

What bureau of government first used punch cards to colect data?

The United States Census Bureau was the first government bureau to use punch cards for data collection. They began using punch cards in the late 19th century to process and tabulate census data. This technology greatly improved the speed and accuracy of data processing and became widely adopted by various government agencies and industries.

What phrase Grace Hopper coined?

There is a google article about her 107th birthday (Dec. 9, 2013) where it describes the "bug" that she found while they were testing the computer (Mark I Electromechanical Computing Machine). The anecdotal story is that the moth they found was a bug and that they debugged the machine.

What is the purpose of a Turing test?

The purpose of a Turing test is to determine a machine's ability to exhibit intelligent behavior that is indistinguishable from that of a human. It tests whether a machine can successfully imitate a human to the extent that another human interacting with it cannot differentiate between the two.

The first electronic computer was built between 1939 and 1942 by?

American mathematician and engineer Howard Aiken in collaboration with IBM. The computer, called the Harvard Mark I, was a massive machine that used more than 750,000 components to perform calculations. It was primarily used for scientific and military calculations and played a significant role in the development of early computing technology.

Where the super computer of India PARAM is placed?

The first Indian Super Computer PARAM 10000devloped by CDAC India is currently situated at PUNE Indiaand is used in atomic research and astronautical research.

Was the Atanasoff-Berry Computer programmable?

No, it was hardwired to solve only one type of problem: solution of systems of simultaneous equations of up to 29 variables. But if necessary Atanasoff could have easily designed a different computer using the same technology and methods that would have been programmable.

Does a system administrator have to log into a users account to view their history?

I assume you mean Web history. And generally speaking no. Then can just look at the logs and see what ip addresses you visited. Also most companies use VNC software, which will allow them to actively connect to a user's PC (as well as monitor what you are doing in real time, even though this is not what it is intended for.) see winVNC or tightVNC. Also most companies setup administrative shares (c:\) so they can backup your data, and move around files for users if needed. This means they can copy any history files off your computer if needed. This would be tedious and very time consuming to look through and unlikely for that reason. If they think you are doing something wrong, they can also capture all your incoming and outgoing packets via a program like wireshark, and figure out exactly what is going on. Some companies also use proxies for web browsing, to make sure employees are not going to anywhere they shouldn't. If your company is running the proxy server they have access to logs which would clearly show where you have been, what sites were blocked, etc. Medium to large companies use commercial grade ISPs which will also monitor live traffic if asked.

WHAT IS ENIC MEAN?

ENIC stands for European Network of Information Centres. It is an organization that aims to promote the recognition of academic qualifications and facilitate the mobility of students and professionals within Europe. ENIC centers provide information and assistance on issues related to recognition of qualifications obtained abroad.

What did the univac predict?

The UNIVAC, one of the earliest electronic computers, did not have the capability to predict or make future projections. It was primarily used for scientific calculations, data processing, and computing tasks.

What Can the eniac do?

multiply divide and count

Each of ENIAC's 20 accumulators could do 5000 additions or subtractions per second. A special panel called the "multiplier" could control 4 accumulators to do multiplication by repeated addition and shifting. A special panel called the "divider/square rooter" could control 5 accumulators to do division by repeated subtraction and shifting or square roots using a modification of the division process. A special panel called the "master programmer" could be programmed to sequence the machine through arbitrary functions or iterative processes.

What is equal to exactly 1024 bytes?

A chunk of data measuring 1024 bytes is equal to exactly 1 kilobyte. These are units of measure for very small units of data.

What Is a Computer modem made of?

A computer modem is made up of various components including a modulator, demodulator, analog-to-digital converter, digital-to-analog converter, signal processor, and a connection interface such as Ethernet or phone line. These components work together to modulate digital data from the computer into analog signals for transmission over a communication medium and then demodulate received analog signals back into digital data for interpretation by the computer.

When you first turn on a computer what is accessed first?

When you first turn on a computer, the firmware known as the Basic Input/Output System (BIOS) or Unified Extensible Firmware Interface (UEFI) is accessed first. This firmware is responsible for initializing hardware components, running a Power-On Self-Test (POST), and locating the bootloader. The bootloader then loads the operating system, allowing the computer to fully initialize and start functioning.

What does J Presper Eckert have to do with the computer?

J. Presper Eckert was an American engineer and computer pioneer who co-invented the first general-purpose electronic digital computer called the ENIAC (Electronic Numerical Integrator and Computer) in the 1940s. Along with his colleague John W. Mauchly, Eckert made significant contributions to the development of modern computing technology.

What did the inventor of this machine need to know while developing the machine?

The inventor of this machine needed to have a strong understanding of the problem they were trying to solve, a deep knowledge of the technology and engineering principles involved, and the ability to design and create prototypes. They also needed to have a grasp of the market and potential user needs, as well as the ability to iterate and improve upon their design based on feedback and testing.

Who was Grace Hopper and what is she famous for?

She was an early computer programmer, famous for many things including writing the first compiler, inventing the word 'debugging' and coming up with possibly my favorite quote of all time: "It's easier to ask forgiveness than it is to get permission".

Very cool lady. Much more info on Wikipedia, you should read it.

Who is Seymour Cray and what was he famous for?

Seymour Cray was a Computer Architect and Computer Designer. He is best known for his work on advanced supercomputers and the founding of the companies Cray Research and Cray Computer Corporation.

His career began at Engineering Research Associates (ERA) in 1951 and when Remington Rand bought the company and incorporated it into their UNIVAC division he stayed.

When UNIVAC's scientific computing division was eliminated in 1957, a number of employees left to form Control Data Corporation (CDC). Cray wanted to leave also, but stayed to complete the prototype of the Naval Tactical Data System that he was then making. When that was completed early the next year, Cray left for CDC also.

After working on several midrange computers for CDC he began work in 1963 on the CDC 6600 which became the first commercial supercomputer in 1965 when the first was delivered to CERN.

Several backwards compatible supercomputers (the CDC 7600, CDC Cyber 70, and CDC Cyber 170) followed.

But when he wanted to design the CDC 8600 in 1972 the company refused to support it at the level he wanted and he left, starting Cray Research with the goal of making an entirely new type of supercomputer: the Cray-1 which came out in 1976. The Cray-2 followed in 1985.

The same thing happened with the Cray-3 at Cray Research in 1989 as had happened with the CDC 8600. So he started Cray Computer Corporation in 1990.

Only one Cray-3 was ever built, it was delivered in 1993 and had many problems.

Work on the Cray-4 began immediately but the company went bankrupt in 1995 before it was finished.

He started a new company, SRC Computers, in an attempt to design of his own massively parallel supercomputers. Design had barely started when Cray died as a result of a car accident in 1996.

Where should an adjustable condenser be set for maximum resolution?

An adjustable condenser in a microscope should be set at the highest position for maximum resolution. This position allows for maximum illumination and better focus of the specimen, resulting in sharper and more detailed images.

What is the old name for router?

Perhaps you are referring to IMP, but these would be more like a modern DSL or cable modem than a router in function.

Was grace hopper married?

Yes, Grace Hopper was married. She married Vincent Foster Hopper in 1930 and they remained married until his death in 1945. After his death, she kept his last name professionally and became known as Grace Murray Hopper.
