Answers
Explanation:
01. Computer is called diligent machine because it can perform the task repeatedly without loosing its speed and accuracy for a long time.
02. Computers are certainly more adept at solving quandaries that benefit from their unique skillset, but humans hold the edge on tasks that machines simply can't perform. Not yet, anyway. Computers can take in and process certain kinds of information much faster than we can.
03. Speed
A computer works with much higher speed and accuracy compared to humans while performing mathematical calculations. Computers can process millions (1,000,000) of instructions per second. The time taken by computers for their operations is microseconds and nanoseconds.
Accuracy
Computers perform calculations with 100% accuracy. Errors may occur due to data inconsistency or inaccuracy.
Diligence
A computer can perform millions of tasks or calculations with the same consistency and accuracy. It doesn’t feel any fatigue or lack of concentration. Its memory also makes it superior to that of human beings.
Versatility
Versatility refers to the capability of a computer to perform different kinds of works with same accuracy and efficiency.
Reliability
A computer is reliable as it gives consistent result for similar set of data i.e., if we give same set of input any number of times, we will get the same result.
04. Firmware is a software program or set of instructions programmed on a hardware device. It provides the necessary instructions for how the device communicates with the other computer hardware.
Examples of firmware include:
The BIOS found in IBM-compatible Personal Computers
Code inside a printer (in addition to the printer driver that is on the computer)
05.An abacus is a manual aid to calculating that consists of beads or disks that can be moved up and down on a series of sticks or strings within a usually wooden frame. The abacus itself doesn't calculate; it's simply a device for helping a human being to calculate by remembering what has been counted.
06. SQL stands for Structured Query Language.
Fourth generation languages are commonly used in database programming and scripts examples include Perl, PHP, Python, Ruby, and SQL.
07. Computer hardware includes the physical parts of a computer, such as the case, central processing unit (CPU), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard.
Software, instructions that tell a computer what to do. Software comprises the entire set of programs, procedures, and routines associated with the operation of a computer system. ... A set of instructions that directs a computer's hardware to perform a task is called a program, or software program.
08.Stands for "Garbage In, Garbage Out." GIGO is a computer science acronym that implies bad input will result in bad output.
09.This generation is based on parallel processing hardware and AI (Artificial Intelligence) software.
10.The computers of first generation used vacuum tubes as the basic components for memory and circuitry for CPU (Central Processing Unit).
11.those using microprocessors, the fourth
12.transistors
13. Professor J. von Neumann
14.There are five computer generations known till date.
