6LoWPAN stands for IPv6 over Low-Power Wireless Personal Area Networks.

It is a protocol defined between Network layer and Data Link layer.

It is defined by the IETF standards RFC 4919, 4944, draft-ietf06lowpan-hc and -nd, -draft-ietf-roll-rpl.

On a broad level, there are two types of computer memories — read only and read or write memory.

1. Read Only Memory (ROM) classifications

In its most simple realization, ROM consists of a pn diode and a tiny metal fuse at the cross-sections of word and bit lines of the memory matrix.

2. What is 802.15.4?

802.15.4 covers all the low power low data rate wireless communication standards in PHY/MAC Datalink layer in the ISO/OSI model.

3. What are the functionalities of Physical layer?

What is it that differentiates a Digital Signal Processor from the processor in your laptop? What are DSP processors used for? Read on to find more about DSP’s.

Any task that a processor does can be broken down into two operations- Data movement or data arithmetics. Not all processors excel in both the fields equally. For example, a processor such as Intel Pentium is designed by keeping in mind data movement operations. It is meant for word processing and such applications. On the other hand, a DSP is built for faster data computation rather than data movement.
