Q. What kind of information can be stored in a database?
In the old days, databases were limited to numbers, Booleans, and text
These days, anything goes
As long as it is digital data, it can be stored:
Numbers, Booleans, text
Sounds
Images
Video
Q. What does NIC stand for?
Network Interface Card
Q. What is Information Technology?
The group of technologies concerned with the capture, processing and transmission of
information in the digital-electronic form.
Telecom Engineering, Computer Science, Computer Engineering, Software Engineering
Q. What is meant by universal access of internet services?
Universal Access
Same functionality to everyone
Q. Write JavaScript code to convert the number 236.2363611111556 into currency format and JavaScript statement to show output.
a = 236.236311111556 ;
b = a.toString( ) ;
decimalPos = b.indexOf( ".", 0 ) ;
c = b.substring( 0, decimalPos + 3 ) ;
document.write( c ) ;
Q. Briefly mention any three problems in old modes of presentation development
It was difficult and often costly to make changes, especially last minute changes
No sound, no animation, and no video
It was difficult keeping track of old ones and making sure of their proper storage
Q. What is the difference between Internet and Intranet ?
The Internet is a global system of interconnected computer networks that use the standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks of local to global scope that are linked by a broad array of electronic and optical networking technologies. The Internet carries a vast array of information resources and services, most notably the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail.
An intranet is a private computer network that uses Internet Protocol technologies to securely share any part of an organization's information or operational systems within that organization. The term is used in contrast to internet, a network between organizations, and instead refers to a network within an organization.
Q. Define the following terms:
A) Heuristic
A procedure that usually, but not always, works or that gives nearly the right answer
Rule of thumb learned through trial & error
Common sense lesson drawn from experience
Qualitative principle, guideline, general judgment
Natural language description of experience
B) System
System
A collection of elements which working together produces a result not achieved by
the things alone
C) System architecture
System Architecture
The structure
(in terms of components, connections, constraints) of a product or a process
D) Analysis of Algorithm
Analysis in the context of algorithms is concerned with predicting the resources that re
requires:
Computational time
Memory
Bandwidth
Logic functions
However, Time – generally measured in terms of the number of steps required to execute an algorithm - is the resource of most interest
By analyzing several candidate algorithms, the most efficient one(s) can be identified.
Q. Write a note on the following (4+6)
Two popular review methods
1. Give the problem statement, design, and code (that includes all assumptions) to a
peer, and ask him/her to see if things have been done properly
2. Walk a peer or a group of peers through the problem, the design, and the code
yourself
Two types of errors
Syntax Errors
• They are caused by the code that somehow violates the rules of the language
• Easy to detect and fix errors
• The browser stops code interpretation on detecting one of these
Examples:
–a = b + * c ;
–receiver = receiver + 2
Semantic Errors
• Occur when a statement executes and has an effect not intended by the
programmer
• Hard to detect during normal testing
• Often times occur only in unusual & infrequent circumstances
• the ‘+’ operator often results in unintended consequences. Remedy: Convert, before use.
