Architecture identifiers

While Choosing the distro you need to select some architecture then. You need to know about it. These are architecture identifiers that specify the type of CPU architecture and instruction set used by a system. Each corresponds to a different hardware or processor family. Here's a brief explanation of each:

1. amd64

• Architecture: 64-bit x86
• Description: Designed for 64-bit processors, initially developed by AMD, but also used by Intel.
• Usage: Most modern PCs and servers.

2. arm64

• 
  Architecture: 64-bit ARM
• Description: Refers to 64-bit ARM processors (also known as AArch64).
• Usage: Modern ARM-based devices like smartphones, tablets, and some servers (e.g., Apple M1/M2 chips).
  

3. armel

• 
  Architecture: ARM (32-bit, little-endian, soft float)
• Description: Used for older or embedded ARM systems, supporting software floating-point operations.
  
• Usage: Embedded devices or legacy ARM platforms.

4. armhf

• 
  Architecture: ARM (32-bit, hard float)
• Description: Supports hardware floating-point operations.
  
• Usage: Raspberry Pi and other ARM-based systems.

5. i386

• 
  Architecture: 32-bit x86
• Description: Refers to 32-bit Intel processors starting with the 80386 (introduced in 1985).
  
• Usage: Older PCs and systems still running 32-bit operating systems.

6. mips64el

• 
  Architecture: 64-bit MIPS, little-endian
• Description: A 64-bit version of the MIPS architecture in little-endian byte order.
  
• Usage: Network devices, embedded systems, or specialized hardware.

7. mipsel

• Architecture: 32-bit MIPS, little-endian
• Description: A 32-bit version of the MIPS architecture in little-endian byte order.
  
• Usage: Older embedded systems and routers.

8. ppc64el

• Architecture: 64-bit PowerPC, little-endian
• Description: A version of the PowerPC architecture for 64-bit systems in little-endian byte order.
  
• Usage: IBM POWER servers.

9. s390x

• Architecture: IBM z/Architecture (64-bit)
• Description: A 64-bit architecture used by IBM mainframes.
  
• Usage: Enterprise and high-performance computing environments.

Text-based User Interface (TUI) commands in Linu

Text-based User Interface (TUI) commands in Linux allow for a graphical-like interface within the terminal, enabling users to interact more visually without needing a full GUI environment. Here are some popular TUI commands and tools in Linux:

System Monitoring and Management

1. htop - An enhanced version of top, showing CPU, memory, and process usage with interactive controls.

        $ htop

2. glances - A comprehensive system monitoring tool that displays CPU, memory, network, and disk usage.

        $ glances

3. nmon - A performance monitor that shows CPU, memory, disk, network, and more.

        $ nmon

File Management

1. mc (Midnight Commander) - A powerful file manager that allows navigation, copying, moving, and editing files.

        $ mc

2. ranger - A file manager with VI keybindings and previews of images and text files.

        $ ranger

3. vifm - A file manager with VI-like keybindings for navigating and managing files.

        $ vifm

Text Editors

1. vim - A highly configurable text editor with TUI, known for its power in text editing.

        $ vim filename

2. nano - A simple and user-friendly text editor for editing text files.

        $ nano filename

3. emacs -nw - Emacs in "no-window" mode runs a powerful editor within the terminal.

        $ emacs -nw filename

Disk and Filesystem Utilities

1. ncdu - Disk usage analyzer, providing a tree-view of disk space usage.

        $ ncdu

2. cfdisk - A partition manager that allows creating and managing partitions.

        $ sudo cfdisk

3. fdisk - A TUI for managing disk partitions.

        $ sudo fdisk /dev/sdX

Network Monitoring and Management

1. nmtui - A TUI for managing network connections.

        $ nmtui

2. bmon - A network bandwidth monitor for real-time bandwidth usage visualization.

        $ bmon

3. nload - Displays incoming and outgoing network traffic in real time.

        $ nload

System Utilities

1. alsamixer - A sound mixer for configuring audio levels.

        $ alsamixer
