Computer Engineering

What is  it  about ?

No technology in the world has shown more rapid progress than that of computers and few technologies have had the impact on our lives and the way we work as information technology. Both these trends will accelerate during the next decade. Computers today are indispensable in optimising performance in almost every field of work from space science, genetic, medical science, meteorology, agriculture, navigation, office automation, teaching to design, music and films. The figure movements and sound of the Dinosaurs in the film `Jurassic Park’ were entirely created by computers.

Computer engineering is the creative application of engineering principles and methods to the design and development of hardware and software systems. A Computer Engineer is someone who

  • designs the control system for an automated production line in the manufacturing industry
  • creates software for digital telephone switching systems
  • plans and supervises the installation of a Local Area Computer Network (LAN)
  • develops a new operating system for a client with specific needs
  • investigates methods of creating smaller, more powerful computer chips using VLSI (Very Large Scale Integration)

Management- IT / Systems

What is Management- IT / Systems?

Management of Information Systems integrates people, technologies, and procedures (the information system) effectively and optimally to solve business problems. It is a combination of two branches of study, information technology and management. It is not a theoretical sudy of computer science but is the application of management techniques in the computer related environment. Management information systems emphasize the collection, organization, analysis and dissemination of information for the planning and control of business or organizational operations.

The programme develops technical skills and administrative insights required for the design, development, implementation, maintenance and management of organizational information systems. The bottom line of the systems management approach to IT and Systems is total quality assurance through process-related improvements in the entire organization.

Wireless and Mobile Technology

What is Wireless and Mobile Technology ?

Pankaj and Mohan were traveling together when they saw an injured man lying on the road, groaning in pain. Fortunately Pankaj had a mobile. He immediately contacted an ambulance and transported the injured man to a hospital where he got medical attention. This saved his life.

Mobile and wireless technology is a blessing of new age technology. It helps you to connect people wherever, whenever.

Communication remains by far the most popular application of mobile wireless technology today. In addition to the traditional modes of voice and text paging, new communication applications are emerging with mobile email and instant messaging. Another important new mobile wireless application, mobile Internet access, makes information available everywhere.  Internet access to news, weather, health, sports, shopping, business, education, and entertainment is becoming available on a variety of different portable devices and supported through several competing types of wireless service.   Mobile Internet access is available on laptop computers and personal digital assistants through local area networks using wireless Ethernet and Bluetooth network access. ...

Voice Technology

What is Voice Technology ?

“Good morning sir, this is Sharon here, how can I help you ?” Sharon, I haven’t received my insurance bonus yet, what is the amount due to me and when should I expect it ?”. “I’ll put you on hold for a minute and get back to you”. Sharon looks up the records immediately and says “The amount due to you this year is 30 dollars and this should reach you in a week”.

Voice technology is about customer relations and much more. “Evolving user interface technology will be critical in overcoming the constraints of today’s wireless data devices” says a voice analyst. Now everyone can make calls, send and receive E-mail, SMS, Paging and Instant Messages from any phone or control device – using only their voice. Voice technology works with mobile phones, PC’s, and other devices and lets people get more done – faster and more easily than ever before.

Voice technologists use speech recognition and speech synthesis to allow you to communicate with the...

Network Systems Analyst

What is Network Systems Analysis ?

Network is the buzz word for the 21st Century. Modern society increasingly depends on large-scale networked systems for business, government, marketing, defense and social life (Orkut, Facebook, etc).

A Case study : Mental health treatment management is often a manual process with handwritten forms and informal communication. As a result, substantial time and effort are consumed to coordinate various treatment

providers, including physicians, social service agencies, and healthcare facilities. A network systems organization developed a large-scale, comprehensive management system to automate, systematize, and integrate

multiple aspects of regional mental healthcare. This system, ultimately contained about 22 subsystems that operate on a distributed client/server network and maintained a large, complex database of patient and provider records.

Network system analysts design and implement systems, network configurations, and network architecture, including hardware and software technology, site locations, and integration of technologies. They maintain the peripherals, such as printers, that are connected to the network; Identify areas of operation that need upgraded equipment such as modems, fiber optic cables, and telephone wires; Train users in use...

Ethical Hacking

What is Ethical Hacking ?

You’re devoted to making your network secure. You’ve applied all the latest patches, updated your virus software, installed an intrusion-detection system, and double-checked the rules on the firewall(s). Nevertheless, you’re still dogged by nagging questions. Have you done enough? Do you know all the weaknesses in your network? Are you truly safe from attackers?

An ethical hacker is a computer and network expert who attacks a security system on behalf of its owners, seeking vulnerabilities that a malicious hacker could exploit. To test a security system, ethical hackers use the same methods as their less principled counterparts, but report problems instead of taking advantage of them. The end result is the company’s ability to prevent an intrusion before it ever occurs.

In a similar but distinct category, a hacktivist is more of a vigilante: detecting, sometimes reporting (and sometimes exploiting) security vulnerabilities as a form of social activism. This includes hacking into a terrorists network and corporate espionage.

Embedded Technology

What is Embedded Technology ?

An embedded system is a special purpose computer used inside of a device. It introduces advanced technologies and solutions for emerging embedded applications, including digital consumer electronics, automotive, wireless/ubiquitous computing and factory automation. Embedded systems were also used in the recent Mars landing and roving robot.

Embedded systems are designed to perform a specific function within a given time frame.
Embedded devices are found inside (besides PCs or workstations) in anything electronic that seems intelligent such as handheld devices like personal digital assistants (PDAs), toys, automobiles, mobile phones, microwave ovens, music systems, digital cameras, access cards, TVs, MP3 players, ATMs, traffic signals and numerous other gadgets that we come across in our every day life.

Embedded technology provides the intelligence of an electronics product; from basic function like sending a SMS on mobile phones to advanced functions like tracking the position of a launched missile. Embedded technologies have enabled and helped the entire electronics industry to grow at a phenomenal rate.
