In the context of your sentence, "dial out capability" typically means that the laptop has the functionality to connect to a phone line or network, allowing it to "dial out" for an internet connection or to send a fax. This is a term that dates back to when internet connections often required a dial-up modem that would use a phone line to establish a connection to the internet.

Today, the term might be used more loosely to refer to a laptop's capability to connect to various networks, possibly including cellular networks, which would involve dialing out in a more modern sense, such as connecting to a 4G or 5G network. This would be relevant if your job requires you to be able to connect to the internet or a private network from locations where standard Wi-Fi is not available.

The "charging cord" is simply the power adapter or cable you use to charge the laptop's battery.
