Hello, lately, I've been having an issue when my iBook G4 didn't recognise my Airport Extreme card during a netinstall of debian and ended up not installing basic packages like gedit, Libre Office, and synaptic. Also any ram I inserted was not recognized. Can anyone help me with the following problems:

No wireless card drivers
missing packages
ram not recognized

Did you install from live-cd/usb?
Are You using unetbootin?

No, just a plain install cd

Not a net install cd how to.
But close for what you are trying to do.
Probably easier to do the net install over a land line though.
Then download and enable wireless then from there.

even the SUDO command is missing

Debian doesn't setup sudo by default, you have to configure sudo from root or just su to root.

@OP: Your wireless issue is almost certainly because your card requires non-free firmware that is in violation of the Debian Free Software Guidelines and so is not supplied on the official ISO images.
https://wiki.debian.org/Firmware

If the card wasn't functional during the installation and you used a netinstall, your system will be very basic indeed and lacking most of the functionality that can be expected from a Debian system.

You could add the "non-free" & "contrib" components to the repository lines in /etc/apt/sources.list and download the non-free firmware (if you have a wired connection available) or you could install the .deb package for the firmware by downloading it on another computer & transferring the package over via USB stick (install using it using gdebi or `dpkg -i <name of .deb>`) and then install all the missing packages manually or you could simply install again using one of the unofficial ISO images that already include the non-free firmware your card requires:

I don't know about your RAM issues though -- are you sure the chip is functional?

If you are using a 32-bit system, it will not recognise RAM above 4GiB anyway; you should install a 64-bit operating system if your machine can make use of it and RAM is not restricted (ie, more than 1-2GiB).
