Computer Networking |

The need for seamlessly moving information
across the globe for many to use and share
through computers and Internet has given birth
to computer networking.
Networking is changing the world of consumer
electronics, biomedicine, industrial automation,
super computing and defense. With the advent of
Ethernet-enabled sensors and controllers,
companies are increasingly looking at hooking
their factory floor to their executive offices
and beyond. Enterprise management is another
widespread application made possible by
networking.The
Work
Computer network management is a purely
technical function. In a world where
connectivity is the key, expertise in networking
can take you places. There are several career
avenues within networking, some of which are the
following: Instead of working in a bank, credit
card company or telecom company where you get to
interact face-to-face with the custom
Network Administration
Working from the concept upwards, network
administration involves configuring and
managing LANs (Local Area Networks), WANs
(Wide Area Networks) and VPNs (Virtual Private
Networks). You will be responsible for
analyzing, installing and configuring the
company’s network even from a remote location.
Monitoring network performance,
troubleshooting problems and maintaining
network security has to be done on a daily
basis. With the proliferation of B2C (business
to customer) websites, e-commerce,
e-governance, VPN (Virtual Private Networks)
and other Internet and telecom-based
applications like remote servicing and IVR
(Interactive Voice Response) the demand for
network administrators is expected to peak in
the next couple of years.
Familiarity with the intricacies of the
specific systems being used by a company:
Windows NT, Novell, Unix, Linux and so forth,
thorough knowledge of networked applications,
security and virus-protection schemes, system
diagnostic utilities and experience with
routers, hubs and bridges is also necessary.
Network Technicians
Focus more on the set up, troubleshooting and
repair of specific hardware and software
products.
Service Technicians
Visit customer sites to perform “field”
upgrades and support functions.
Network Programmers and Analysts
Write software programmes or scripts that help
evaluate third party products and integrate
new software technologies into an existing or
new network environment.
Network Managers
Supervise the work of administrators,
engineers, technicians and programmers. They
also work at long-range planning and strategy.
At the entry level you will be focusing on
tasks such as troubleshooting, monitoring, LAN
performance, adding or deleting users, adding
new servers, etc.
Network Security
As more and more organizations move their
offline transactions online and vast
quantities of vital and sensitive data travels
through networks, the need for developing
“fool proof” e-security systems to safeguard
the networks and databases from rampant
cracking has emerged as the number one IT
concern globally. And consequently, it is one
of the hottest and most sought-after
specialties.
With over 300 new viruses released everyday
and rampant hacking (82,000 recorded cases,
according to a Carnegie Mellon University
study, governments and corporations have
beefed-up their IS spend and tightened access
to their systems and core applications. They
are looking for people who can administer
their enterprise network security safely and
securely as a strategic priority.
To excel in this field, you must be as
familiar with system programming and
administration as with security configuration
and firewalls. This also includes knowledge of
advanced TCP/IP, security fundamentals,
security implementation, router security and
attack routes.
Employment Opportunities
The Indian market for computers and peripherals
has been growing at a rapid pace. In fact, the
networking market is one of the fastest growing
segments in the industry. Over three million
units were sold in FY 2003-04 and the figure is
expected to grow by 40 per cent crossing the 4.2
million mark in 2004-05. Driving this boom are
technological innovations and a drop in prices,
thanks to the IT agreement under the WTO, which
will soon come into effect (translating into a
PC penetration of 20 per 1000). Going by the
average requirement of one hardware engineer for
every 50 machines, the demand for networking
professionals is bound to increase.
Moreover, Internet usage is increasing by the
day and correspondingly the need for larger
bandwidth for simultaneous transfer of data,
voice and visuals (still and streaming video).
The spurt in demand, has in turn, spurred the
need for next generation data services like
broadband access, virtual private networking,
Voice over Internet Protocol (VOIP) and hi-tech
Video Conferencing. With the tremendous growth
in telecommunications and networking, people
with good knowledge of computer network
management on various platforms are in high
demand. No doubt then, that there’s a
considerable demand gap in the availability of
networking professionals globally. Whereas over
1,00,000 networking technicians and engineers
are required, there are barely 50,000 of them
presently.
What it
takes?
Knowledge of computer hardware is the foundation
for a career in computer networking. A good
course will familiarise you with the basics of
operating systems, microprocessors, peripheral
devices, computer architecture, assembly and
disassembly, installing various software,
configuring PCs, preventive maintenance and
troubleshooting.
This can be followed by a relevant course/s or
certification in networking to gain expertise in
LAN and WAN, which is in high demand.
LAN shares the information and resources within
the premises through the intranet with the help
of products like Windows NT or Windows 2003 from
Microsoft, Unix from SCO, Solaris from Sun
Microsystems, Netware from Novell, etc. It can
be further connected to the Internet through
internetworking devices such as Routers and
Switches.
WAN is a combination of Internet and Intranet —
a network of networks, as it were.
Vendor certifications like Microsoft’s MCSE or
Cisco’s CCNA or CCNP or CCIE, or Novel’s CNE or
Sun Microsystems’ Sun Solaris Administrator at
the higher end, are increasingly sought by
recruiters.
