The energy density of a fuel per unit mass
is called the specific energy of that fuel.
The coconut shell has a high calorific value
of 20.8MJ/kg and can be used to produce
steam, energy-rich gases, bio-oil, biochar
etc. The "caloric content" dried wood is
about 19 to 20 MJ/kg. While one dung cake
of an average size gives 2100 kJ worth of
energy.

There was once a time when CPU clock
speed increased dramatically from year to
year. in the 90s and early 2000s processors
increased at incredible speeds, shooting
from 60 MHz Pentium chips to gigahertz level
processors within a decade. But around
2005, the top CPU clock speed of the high-end
processors settled around 4 GHz and
hasn't increased much since then. Now
greater improvements in power come from
multi-core processor designs. As a result,
we see chips like AMD's recent offerings,
with a dramatically increased number of
cores. These modern transistors and Chips
have increased the power of processors.
Thus CPU clock speed need not to increase.
A local-area network (LAN) is a computer
network that spans a relatively small
area. Most often, a LAN is confined to a
single room (with any brand of computer),
building or group of buildings; however,
one LAN can be connected to other LANs
over any distance via telephone lines and
radio waves. The acronym ISP is 'internet
service provider'. It provides services for
accessing, using, or participating in the
internet.
The National Policy of Education of 1986
and Programme of Action of 1992 provided
a significant formulation regarding the
content and process of education. District
Institutes of Education and Training (DIET) should be established with the capability
to organize pre-service and in-service
courses for elementary school teachers
and for the personnel working in nonformal
and adult education. As DIETs get
established, sub-standard institutions should
be phased out. Selected Secondary Teacher
Training Colleges should be upgraded to
complement the work of the State Councils
of Educational Research and Training.
