Huzaifa is a grade 5 student who is very enthusiastic to learn coding in computers. He asks his computer teacher to help him choose a language to code. Which level language will the teacher recommend Huzaifa?

Answers

Answer:

High level language.

Explanation:

High level language can be defined as a programming language which is generally less complex than a machine (low level) language and easy to understand by the end users (programmers).

This ultimately implies that, a high level programming language is typically a user friendly language and as such simplifies coding or programming for beginners.

Some examples of high level programming language are Python, Java, C#, Ruby, Perl, Visual Basic, PHP, Cobol, C++, Fortran, Javascript, etc.

In this scenario, Huzaifa is a grade 5 student who is very enthusiastic to learn coding in computers. He asks his computer teacher to help him choose a language to code. Thus, the language level the teacher will recommend to Huzaifa is a high level language.

WiFi can be defined as a wireless local area network that allows network devices such as access points (APs), computers (both laptops and desktops), smartphones, smart televisions, etc., to communicate with each other wirelessly over a short-ranged network. It is a standard communication network that uses radio waves to establish a channel (medium) between multiple network devices.

This ultimately implies that, the network range or distance covered by WiFi is largely dependent on transmission power and frequency. The standard range or distance covered by WiFi is about 50 meters (160 feet).

Hence, a short-range wireless network is called WiFi.
