What is a computer?

 A computer is a machine that can store and process information. Most computers rely on a binary system, which uses two variables, 0 and 1, to complete tasks such as storing data, calculating algorithms, and displaying information.


Computers are dumb devices with zero intelligence quotient (IQ). They cannot visualize and thinking what exactly to do under a particular situation, unless they have been programmed to tackle that situation. Computers must be directed to perform each and every action. Was this answer helpful?


All basic computers consist of four functions: input, storage, processing and output. IPO is often called IPOS or input, process, output, storage. The computer receives input, processes the input as per user instructions and provides output and can be stored in a desired format.

characteristics of algorithm

 What are the 5 characteristics of an algorithm? The 5 Properties of Algorithms Input specified. Output specified. Definiteness. Effectiveness. Finiteness. What are the characteristics of an algorithm? What Is An Algorithm? Characteristics, Types and How to write ... Unambiguity, fineness, effectiveness, and language independence are some of the characteristics of an algorithm. The scalability and performance of an algorithm are the primary factors that contribute to its importance. Characteristics of an Algorithm Input − An algorithm should have 0 or more well-defined inputs. Output − An algorithm should have 1 or more well-defined outputs, and should match the desired output. Finiteness − Algorithms must terminate after a finite number of steps. What are the 4 types of algorithm? There are four types of machine learning algorithms: supervised, semi-supervised, unsupervised and reinforcement.

What Sound Does a Giraffe Make? Guide: 6 Giraffe Noises

 Giraffes are notoriously quiet. What sound does a giraffe make? In this post, you’ll learn what sounds they make and what they mean. (Spoiler- giraffes make snorts, grunts, hisses, bellows, coughs, moos, and more). You’ll also learn about giraffe humming and infrasound. Are Giraffes Physically Capable of Making Sound? Yes, giraffes are physically able to make sound, that is to say, that they do have a larynx that contains vocal cords. However, because of their narrow trachea (windpipe), long neck (6.6-7.9 feet /2-2.4 meters), and comparatively small lung capacity, it is a challenge for them to produce enough airflow to vibrate the vocal cords. So while they can make various noises, most of the time they choose not to. Another reason for the lack of vocal communication is that giraffes are great at communicating visually. They have excellent eyesight, and with their height can see far into the distance. Some of their actions including stamping their feet, tossing their head, and wa...
