Why is the keyboard calledQWERTY

2 answers:

I believe it is because the arrangement of the first six letters in the top alphabet row of a standard keyboard QWERTY goes way back. The layout was created in 1873 when Christopher Latham Sholes made improvements to his earlier typewriter models in order to design a quicker and more efficient typewriter for E. Remington and Sons.

The standard QWERTY layout keyboard is called 'QWERTY' because on the top line of the keyboard the first 6 letters from chronological left to right order are; Q, W, E, R, T, and Y.

Or...if you're wondering why it's QWERTY and not ABCDEF, it's because when typing with the alphabetical format, many of the keys would clash with each other due to the arrangement of keys on the original typewriter. The QWERTY layout became so popular, it was the standardized layout for typewriters, and even keyboards today.

jeyben [28]

Answer:

Metrical task system algorithm is the online algorithm that is used for organizing the online problems like k-server issues, paging issues etc.This task system works in the form of metrics to decrease the complete cost experienced due to processing of the operation and analyzing the competition.

It can be used for the online shopping project for the analyzing the comparison between the performance on basis of online and offline trends and then optimization can take place according to the the results.

What is Robotics?

Robotics is the branch of technology that deal with the design, construction, operation and application of robots as well as computer system for there control, sensory feed back, and information processing. the design of given robotic system often contain principle of mechanical or electronic engineering and computer science. The word robotic was first used in 1941 by the writer Isaac Asimov.

Branches of robotics:

Artificial intelligence: The developing of an intelligence of machine and is a branch of computer science.

Nano Robotics : the field of creating machines that are at a scale of a nano meter.

Tele-presence: The study given to an illusion of being at a place without being there physically.

Robot Locomotion: The study of method that Robots used to transport them selves from place to another.

Robots have long captured the human imagination but despite many advances robots have yet to reach the potential so often envisioned in science fiction today engineers and computer scientist are still pursuing one missing ingredient high intelligence it would be nice for example: if robots possessed the intelligent needed to cope with uncertainty, learn from experience and work as team.

Intelligent robots will be one of the engineering achievement of 21 century said Junku Yuh, how leads the robotics program in the national science foundation computers and information science and engineering directorate "we will see them more and more in our daily life".

Which one of these is the most commonly used hardware interface for attaching peripherals to a microcomputer?

Tanzania [10]

Hey there!

The most commonly used hardware interface for attaching peripherals to a microcomputer is the universal series bus, or USB, port. Many computers have at least 2 to 4 USB ports that allow for multiple devices to be plugged in at once. In terms of wired devices as opposed to wireless, this is the main way that a mouse, a keyboard, a smartphone (for charging and syncing information), and many other devices are connected to computers.

Hope this helped you out! :-)

a password to a certain database consists of digits that cannot be repeated. if the password is known to consist of at least 8 d

BaLLatris [955]

Answer:

$\frac{10!}{2}mins$

Explanation:

12 seconds to try one combination will be equivalent to $\frac{1}{12}\times 60 = \frac{1}{5} \ mins$

Password contain at least 8 digit i.e. password can contain 8, 9, 10 digit.

Password cannot contain more than 10 digit because it will give room for repetition which it is clearly stated that digit cannot be repeated.

Possible digit that can be used: 9,8,7,6,5,4,3,2,1,0.

Total number of passwords combination possible for each position in 8 digit.

1st position = 10, 2nd position = 9, 3rd position = 8, 4th position = 7, 5th position = 6, 6th position = 5, 7th position = 4, 8th position = 3. Total number of passwords combination possible in 8 digit is equivalent to $\frac{10!}{2}$ .

Total number of passwords combination possible for each position in 9 digit.

1st position = 10, 2nd position = 9, 3rd position = 8, 4th position = 7, 5th position = 6, 6th position = 5, 7th position = 4, 8th position = 3, 9th position = 2. Total number of passwords combination possible in 9 digit is equivalent to $\frac{10!}{1}$ .

Total number of passwords combination possible for each position in 10 digit.

1st position = 10, 2nd position = 9, 3rd position = 8, 4th position = 7, 5th position = 6, 6th position = 5, 7th position = 4, 8th position = 3, 9th position = 2, 10th position = 1. Total number of passwords combination possible in 10 digit is equivalent to 10!.

Adding them up and multiplying by $\frac{1}{5} \ mins$ to get the total number of time needed to guarantee access to database = $[\frac{10!}{2}\times\ \frac{10!}{1} \times 10!] \frac{1}{5}\ mins = \frac{10!}{2}$
