18.4.2 Remote Drive Connection Using SCP Program
SCP (Secure Copy) is a program that sends and receives files to and from a remote computer using SFTP or SCP protocol through SSH.
18.4.2.1 Installing/Enabling SSH server Program
This program basically assumes that SSH server of the remote computer is running. To do this, you must first enable the SSH server in the Raspberry Pi system. For details, see the description of [9.9.1 Enabling SSH].

First, we install the
18.3.2 Desktop GUI connection Using VNC Program
VNC (Virtual Network Connection) is a connection method that connects to a remote computer from my local computer and provides the ability to control the computer at will as if it were my own computer.
VNC program consists of a VNC server and a VNC client, each of which interacts with each other remotely.
18.3 Remote Desktop GUI connection
18.3.1 Remote Desktop Connection Using
As a way to connect to Raspberry Pi system from MS Windows, you can use “Remote desktop connection” method which is used as standard when connecting to remote system from MS Windows.
18.2.4 SSH Connection with
SSH client program is required to access Raspberry Pi system with SSH in MS Windows. There are a number of programs that can be used as SSH clients, and you can use anyone that supports SSH.
Here, we will use the Putty program, which is free and offers a lot of features, so many people use it as standard. PuTTY is a program developed by Simon Tatham that provides Telnet and SSH functions on MS Windows or Unix series computers, and basically provides functions which is the type of terminal emulator. To download the Putty program, you can use the following URL:
18.2.3 SSH Connection on Unix/Linux Series, and Apple Mac
The SSH client program is installed by default in these operating systems, so no separate program installation is required. To connect to the Raspberry Pi system using SSH, use “ssh” command. The following command is a command format on Linux. The command on Apple Mac is similar, and check details if necessary.
18.2.2 Configuring SSH Server
To remotely connect to the Raspberry Pi system via SSH, the SSH server in the Raspberry Pi system must be enabled. To configure the SSH server on the Raspberry Pi system, use the “raspi-config” command. For details, see the description of [9.9.1 Enabling SSH].
18.2 Remote Terminal Connection
18.2.1 Features of SSH
There are several programs that support remote terminal connections. In the past, a program called Telnet that supports remote terminal connections has been used widely. However, this program has a serious security problem because it transmits communication data in a text format without encrypting it, so it is rarely used now.
.3 SD Card Slot
Raspberry Pi supports SD card which is a type of flash memory for a storage device for installing operating system or storing necessary data. The SD card has less capacity and performance than a hard disk, but it has the advantage that it consumes less power than a normal hard disk.
In Raspberry Pi, an SD card has a special meaning, unlike in other computer systems. When Raspberry Pi is powered up and started for the first time, a special program called Boot Loader is supposed to read the operating system installed on Raspberry Pi from the SD card. If you do not have an SD card or you do not have the proper operating system installed on your SD card, you can not start the Raspberry Pi system.
2.8 GPIO
Raspberry Pi is not only able to use the resources in the system, but also has functions to communicate with various external devices and control them through the interface. It can process input or output with an external device, or adjust an external device. It is possible to implement a function of receiving various measurement values from an external sensor to judge a situation and performing appropriate processing accordingly. It is also possible to build a system that directly controls an external system by creating an Embedded Program.
