But what to do with the web site ? It has taken >12 man years of work to create a repository of knowledge on many aspects of the art and science of embedded microprocessor development and even after closing the shop it still gets over 4,000 visitors per month. So as a service to my customers I have decide to keep it live providing my technical insights on the products and then redirecting viewers to sites where they can purchase the items they used to buy from us. Follow the link "Home" The "Information zone" consists of articles produced as background tutorials on subjects of interest to those designing new products. As different CPUs have became available this has lead to new development techniques and in particular to new ways of communicating between nodes.

Plain man's guide to
TCP/IP and related Mnemonics
| 802.11 | A radio LAN standard | This is one of the standard for wireless networks (AKA Wi-Fi) |
| AKA | Also Known As | Not an internet specific abbreviation but here to avoid confusion |
| ARP | Address Resolution Protocol | Translates an internet address into a hardware address |
| BOOTP | Bootstrap Protocol | For remote booting of diskless devices |
| CGI | Common Gateway Interface | A standard that allows web pages to invoke and pass data to Server programs |
| CHAP | Challenge Handshake Authentication Protocol | A PPP option that allows both ends to use passwords to check for a valid connection |
| CIFS | Common Internet File System | Networked access to Microsoft Windows file systems and peripherals (AKA SMB) |
| CSLIP | Compressed Serial Line Interface Protocol | Compressed version of SLIP |
| DHCP | Dynamic Host Configuration Protocol | Allocates IP addresses dynamically |
| DNS | Domain Name Server | A program / computer that converts a domain name into it's IP address |
| FTP | File Transfer Protocol | An application that transfers files across the network |
| HTML | Hyper Text Mark-up Language | The standard used to create web pages |
| HTTP | Hyper Text Transfer Protocol | The protocol used to transmit web pages |
| ICMP | Internet Control Message Protocol | Used to report errors from IP level and above |
| IGMP | Internet Group Management Protocol | Used when broadcasting to groups that exist across routers. |
| IMAP | Internet Mail Access Protocol | A relatively new advanced email Server that allows users to hold and manage their emails on the Server. |
| IP | Internet Protocol | The mechanism for delivering packets across the network |
| IPv6 | The next proposed version of Internet Addressing Protocol | Able to address many more items on a network this extension to IPv4 is still a few years away from normal use. |
| IPCP | IP Control Protocol | PPP's control protocol |
| IPSec | Secure Internet Protocol | A secure version of IP |
| IIOP | Internet Inter ORB Protocol | Protocol for passing object data |
| ISP | Internet Service Provider | A company that links an end user to the Internet backbone |
| LCP | Link Control Protocol | A PPP option negotiation |
| MIB | Management Information Base | A table of devices used by SNMP |
| MIME | Multi Purpose Internet Mail Extensions | Standard for adding diverse types of files to emails |
| MFS | Microsoft File System | Used by Microsoft OSs to link file systems across networks. |
| MTA | Mail Transfer Agent | An application for sending emails |
| MUA | Mail User Agent | An application for creating and reading emails |
| NAT | Network Address Translation | A method of connecting multiple computers to any IP network using a single IP address. |
| NFS | Network File System | A protocol for controlling remote NFS file systems |
| NTP | Network Time Protocol | Used to set the clocks on multiple machines across a network |
| ORB | Object Request Broker | Standard for object data interchange |
| PAP | Password Authentication Protocol | PPP password |
| PING | A diagnostic program | It tests the connection with a specified URL |
| POP3 | Post Office Protocol | A mail protocol that can include attachments |
| PPP | Point to Point Protocol | Supports simple (typically serial) links between computers on a network |
| PPPoE | Point to Point Protocol over Ethernet | Allows applications written for PPP to run across Ethernet links |
| RARP | Reverse Address Resolution Protocol | Allows a host to obtain it's IP address by sending it's hardware address |
| RIP | Router Internet Protocol | Used to control Routers |
| SLIP | Serial Line Interface Protocol | Simple protocol often used with RS232 |
| SMB | Server Message Block | Networked access to Microsoft Windows file systems and peripherals (AKA CIFS) |
| SMTP | Simple Mail Transfer Protocol | Protocol for sending and receiving emails. Messages must be text |
| SNMP | Simple Network Management Protocol | Protocol used by computers that monitor and manage network activity to communicate with one another and the computers they are monitoring Comes in 3 versions: v1 Simple – Simple v2 Some Security v3 Advanced Security & Encryption |
| SNTP | Simple Network Time Protocol | Synchronises clocks across a network |
| SSL | Secure Socket Layer | Sits below TCP, UDP and uses encryption and certification to provide commercial levels of security. |
| TCP | Transmission Control Protocol | Puts data into packets for delivery by IP |
| TELNET | An application that allows logging into remote computers | |
| TFTP | Trivial File Transfer Protocol | TFTP is a subset of FTP which does not require valid username and password. |
| TLS | Transport Layer Security | Like SSL which it supersedes uses encryption and certification to provide commercial levels of security. |
| UDP | User Datagram Protocol | Protocol found at the internet layer along with the TCP protocol. UDP does not guarantee reliable, sequenced packet delivery. If data does not reach its destination, UDP does not retransmit as TCP does |
For more Information: |
|
| MicroNet stack | A stripped down TCP/IP stack that is small enough to be suitable for 8 and 16 bit micros. It has drivers for Ethernet and PPP as well as FTP and Web server packages available. |
| RT-IP TCP/IP stack | A full stack with device drivers and network applications such as FTP, Mail and embedded Web servers and browsers. |
| TCP/IP Paper | Still Confused? - download a white paper designed to introduce Embedded 8 & 16 bit engineers to the possibilities and pitfalls of TCP/IP |
| EBS and RT-PX | Suppliers of RT-IP and a free multi-tasking executive. |
