4. Multiscreen systems
It is the use of multiple
physical display devices, such
as monitors, televisions, and
projectors, in order to
increase the area available for
computer programs running
on a single computer system.
The system can be run by a
single CPU or multiple CPUs
Multi-head may increase the
productivity by up to 40-50%.
5. Super Computers
A supercomputer is a computer which
increases processing capacityparticularly speed of calculation.
These systems work in two ways :
In one approach is a large number of
computers distributed across a
network devote some or all of their
time to solving a common problem
each individual computer receives and
completes many small
tasks, reporting the results to a
central server which integrates the
task results into the overall solution.
In another approach, a large number
of dedicated processors are placed in
close proximity to each other; this
saves considerable time moving data
around and makes it possible for the
processors to work together, for
example in mesh architectures.
Cray Titan – 17.59 PetaFLOPS
6. Supercomputers are used
for a wide range of
computationally
intensive tasks in various
fields.
Quantum mechanics.
Weather forecasting
Climate research
Oil and gas exploration
Molecular modeling
Aerodynamics
Counter-cryptography.
NUDT Tianha – 33.86 PetaFLOPS
7. Radio dog collar
Used for tracking
Works on radio waves
of particular frequency
Has to be in Line of
sight
Can be used as a
communication means
also.
8. Servers
A server is a system that
responds to requests across a
computer network to provide a
network service.
Servers are computer
programs running to serve the
requests of other
programs, the clients.
Thus, the server performs
some task on behalf of clients.
Servers can be run on a
dedicated computer, which is
also often referred to as "the
server", but many networked
computers are capable of
hosting servers.
Typical computing servers are
• Database server
• File server
• Mail server
• Print server
• Web server
• Gaming server, etc.
9. Internet
It is a global system of
interconnected computer
networks that use the
standard Internet protocol
suite (TCP/IP) to serve several
billion users worldwide.
It is a network of networks
Consists of millions of
private, public, academic, bus
iness, and government
networks, of local to global
scope, that are linked by a
broad array of
electronic, wireless and
optical networking
technologies.
12. Computer worms
A worm is designed to
tunnel into your system
and allow malicious users
to control your computer
remotely.
Does not require an
action to spread
Can make multiple copies
of itself. (E-mail)
Slows down computers n
networks significantly.
13. Transatlantic Telecommunication Cable
A transatlantic
telecommunications
cable is a submarine
communications
cable running under
the Atlantic Ocean.
All modern cables
use fiber
optic technology.
14. Most such cables
connect London, Englan
d to New York City, USA
Built mainly for high-
speed requirements of
international financial
transactions.
Financial trading firms
spend billions of dollars
annually to get an edge
on trading
