The Smallest Computer in the World

Main Features

Picotux is the smallest series of Linux computers in the world. The smallest of the lot is the Picotux 100. It measures 35x19x19 mm and can be compared to the size of an 8P8C modular connector. Some of the main features of the Picotux are elaborated in this guide.

Communication Interfaces

The Picotux has a couple of communication interfaces:

The Picotux is built on the platform of uClinux and busybox. You may even use it as a simple telnet or web server. But if you face any difficulties when using Picotux as a web server or in programming, it is better to ask for help. You can leave a request – do my programming homework on a specialized site. We are sure that, getting programming help, you will work with Picotux successfully.

Technical Specifications

The main technical specifications of the Picotux 100 are as following:


The Picotux stands out for its network capability. It uses DHCP for determining the IP address, when on reset or power-up. The Ethernet Interface is powered up only during startup. The local loopback can be enabled using a command. Similarly, TCP/UDP can be used for inter process communication using a command. It is simple to programme the networking IO. You can use the standard Berkeley sockets.


Picotux doesn’t have any MMU. Therefore, the fork() system function gets replaced by vfork(). You can perform multi processing using sub-process programming code in separate exec() functions. Therefore, dynamic allocation of memory needs to be done carefully. Picotux’s root file system is read-only and all the startup options are preset. It has a mnt directory that can be used for attaching NFS network shares.

Thus, the smallest Linux computer is capable of performing some of the functions of its larger counterparts.
