What is a computer? - 🧠ANSWER ✔✔A computer is a device that accepts

information (in the form of digitalized data) and manipulates it for some

result based on a program or sequence of instructions on how the data is to

be processed.

Computers also include the means for storing data (including the program,

which is also a form of data) for some necessary duration. A program may

be invariable and built into the computer (and called logic circuitry as it is

on microprocessors) or different programs may be provided to the

computer (loaded into its storage and then started by an administrator or

user).

Linux Version "Debian" known as "Raspbian"


What are some applications software for Rasp Pi? - 🧠ANSWER ✔✔Surf

Internet with a Browser, High Definition Video, Spreadsheets and Word

Processing, Games

What are some of the compilers and interpreters used with a Rasp Pi? -

🧠ANSWER ✔✔Compilers and Interpreters: C, C++, Java, Python, R, etc.


What is a Raspberry Pi? - 🧠ANSWER ✔✔Raspberry Pi is a low cost, credit

card sized computer that can plug into a display monitor or TV, standard

keyboard and mouse, hard disk and USB storage devices and connect to

the network wired or wirelessly.


How much memory does a Raspberry Pi have? - 🧠ANSWER ✔✔1GB RAM


CPU of Raspberry Pi - 🧠ANSWER ✔✔1.2 GHz Quad-Core ARM Cortex


-(The ARM Cortex-A9 MPCore is a 32-bit processor core)


What's Headless mode? - 🧠ANSWER ✔✔Raspberry Pi is typically used in

environments where attaching a display, keyboard, mouse, etc., is not
