The command apt install bc sysstat is used on systems that utilize the apt package manager (typically Debian-based Linux distributions like Ubuntu) to install the bc and sysstat packages. Here's what each package does:

1. bc:

   • Stands for "Basic Calculator."
   • It is a command-line calculator that allows for precision arithmetic and mathematical operations, including floating-point calculations. It is often used in shell scripts for numerical computations.

2. sysstat:

   • A package that includes a collection of performance monitoring tools for Linux systems.
   • It provides utilities like iostat, sar, and others to monitor CPU, memory, disk I/O, and other system performance metrics.

In summary, this code installs the tools necessary for performing mathematical calculations (bc) and for monitoring system performance (sysstat).
