IMS-1

IMS-1 is an Earth observation satellite in a sun-synchronous orbit. The satellite which is the fourteenth satellite in the Indian Remote Sensing (IRS) satellite series has been built, launched and maintained by the Indian Space Research Organisation (ISRO). IMS-1 is the first satellite to use ISRO's Indian Mini Satellite bus.

It was launched by the Polar Satellite Launch Vehicle - C9 on April 28, 2008 along with the Cartosat-2A and eight nano research satellites belonging to research facilities in Canada, Denmark, Germany, Japan and the Netherlands.

Intersil 6100

The Intersil 6100 family consisted of a 12-bit microprocessor (the 6100) and a range of peripheral support and memory ICs developed by Intersil in the mid-1970s. The microprocessor recognised the PDP-8 instruction set. As such it was sometimes referred to as the CMOS-PDP8. Since it was also produced by Harris Corporation, it was also known as the Harris HM-6100. The Intersil 6100 was introduced in the second quarter of 1975, and the Harris version in 1976.

The 6100 family was produced using CMOS rather than the bipolar and NMOS technologies used by its contemporaries (Z80, 8080, 6502, 6800, 9900, etc.). As a result of its CMOS technology and low clock speeds (8 MHz max. for the Harris HM-6100A), it had relatively low power consumption (less than 100 mW at 10 V/2 MHz) and could be operated from a single supply over the wide range of 4–11 V. Thus, it could be used in high reliability embedded systems without the need for any significant thermal management, if the rest of the system was also CMOS.

Instant messaging

Instant messaging (IM) is a type of online chat which offers real-time text transmission over the Internet. A LAN messenger operates in a similar way over a local area network. Short messages are typically transmitted bi-directionally between two parties, when each user chooses to complete a thought and select "send". Some IM applications can use push technology to provide real-time text, which transmits messages character by character, as they are composed. More advanced instant messaging can add file transfer, clickable hyperlinks, Voice over IP, or video chat.

Non-IM types of chat include multicast transmission, usually referred to as "chat rooms", where participants might be anonymous or might be previously known to each other (for example collaborators on a project that is using chat to facilitate communication). Instant messaging systems tend to facilitate connections between specified known users (often using a contact list also known as a "buddy list" or "friend list"). Depending on the IM protocol, the technical architecture can be peer-to-peer (direct point-to-point transmission) or client-server (a central server retransmits messages from the sender to the communication device).
