What is a client side script?
It’s a small program that is a part of Webpage and run on the Clients, they interact with the user
to collect information or to accomplish the tasks. When it succeeded to collect the information
they pass the collected information to Server-Side Script.
Reduced Server Load
Reduced Network Traffic
Don’t send incomplete/incorrect/missing data to user’s browser.
Disadvantages:
Don’t work with all Browsers
Scripting may be turn off by user
Increases the complexity of the Webpage.
What is JavaScript?
It’s a programming language and designed to work with browsers developed by Netscape
and designed to develop small program called Client-Side Scripts and that can used in
HTML WebPages. JavaScript is a Case Sensitive language, and it is an interpreted language and
supports Event-Driven programming & it’s also a Object Based.
Some Things That JavaScript Can’t Do:
JavaScript can’t do “Read” “Modify” “Rename” “Delete” “Create”
What Is Object?
It is a named collection of methods and properties.
Types of Object:
There are three types of object
1 JavaScript objects (are part of JavaScript like window, document)
2 Browser objects ( are that objects that contain information about itself)
3 User-defined objects
Methods are function that are used to manipulate with the Object like (window. close)
Here (window is a Object and close is a Method)
What Is EVENT HANDLERS?
Objects are made up of methods and properties, many object also have event handlers. “Events”
are action that occurs with user interaction with the internet browser.
What Is Programming?
A process in which we tell the computer what needs to be done or what to do.
Types Of Programs:
There are two types of programs
1 Batch Programs
2 Event – Driven Programs
1) Batch Programs:
These program starts automatically via a scheduler like
Initializing the internal data
Reading input data
After reading process that data
After processing print that data
(Important) > No user interaction on those types of programs
2) Event – Driven Programs:
These program starts with user interaction e.g. Microwave Oven, GUIs, Camera
Events that user Does: It’s when user click the mouse button
Things the system itself Does: It’s when system automatically updating the Clock
Loops
Conditions
All Types Of Program Consist Of:
Sequence of instruction
Types Of Programming Languages:
Machine Language (Low Level Programming Language)
Assembly Language
High – level Language (High Level Programming language)
Object Oriented Language
Database Query Language
Procedural Language
Machine Language:
Consist of numbers only & 0s and 1s and this language is not close to human language &
difficult to understand by the computer user. Each type of microprocessor has its own Machine
Language; this is only a language that a computer understands easily without any translation.
Assembly Language:
That type of language that lay between Machine Language and High-Level Language.
In High-Level language you write code in English language. This language is user
friendly, because user can understand the code easily e.g. C++, COBOL, V.B, FORTRAN.
Object Oriented Language:
In object oriented language work is done on the object action, this language is better than
Procedural Language e.g. JAVA, C++.
Database Query Language:
In Database Query Language records are kept in tables permanently and each table is
related with each other e.g. now a days SQL is used for this purpose.
Procedural Language:
In Procedural languages program is written in a sequence e.g. COBOL, FORTRAN.
What Is Compiler?
Compiler is a program that translates the whole program from bottom to top or top to
bottom at a time. It tells you all errors in your program at a time and it is faster than an
interpreter.
What Is Interpreter?
Interpreter is also a translator that translates the program line by line. It doesn’t translate
the whole program at a time. It doesn’t tell all errors in your program but it tells you line by line
and it is slow in speed.
What Is Software Life – Cycle?
It is a sequence of phases we can say that it’s a step of new born to death.
Simple Software Life Cycle:
Concept & Feasibility (what needs to be done, what should be in it, has any scope) User
Requirements (what user want in his website, possible solution needed, lose form) Developer
Specification (how much developer make, structured form) Planning (think & plan that how to
make it) Design (comes after reading developer specification)Implementation (design
is complete now it’s time for coding) Integrating & Testing Operation & Maintenance Retirement
What is Variable?
We can say that Variables are the References of DATA like (x < 6) here x is a Variable.
What is Identifiers?
These are the names used by JavaScript to refer to Variable.

Computer network mean where multiple computers are connected together to share
information.
Components of Computer Network:
Computers
Network interface Cards (NIC) (NIC communicate over a network)
Hub (network traffic controller)
Cables (either electrical or optical)
Protocols (rules governing of communication over a network)
What is Hub?
Hub is a device that is used to connect several computers through a network, it has
several ports, and we can say that Hub is a network traffic controller. E.g. any computer on the
network wants to send message to other computer on the same network first send to Hub, now
Hub broadcast it to specific one.
What is Packet?
Packet is a smallest unit of data that is transmitted over a computer network. Any message that is
transferring over the network is broken into small packets and these packets travel independently
and each packet contains the following information:
Sender’s Address
Destination Address
Error Recovery Information
Types of Computer Network According to the Network Access policy:
There are two types of computer networks according to network access policy.
Private Networks
Public Networks
Virtual Private Network
1. Private Networks: -
Organizations have many computers to connect them on the network, they usually
connect those computers via Private Network and these computers are restricted only authorized
computer access them. The purpose of these computers is to exchange the information to other
computers within the organization and to protect from the outsiders.
2. Public Networks: -
All networks that are not private are Public Networks. The communication
equipment used in these networks is generally used by the user.
3. Virtual Private Network
VPN is a secure, private network. VPN is use for public telecom infrastructure,
maintaining privacy through security procedures.
Types of Computer Networks:
There are three types of computer networks.
LAN (Local Area Network)
WAN (Wide Area Network)
MAN (Metropolitan Area Network)
LAN (Local Area Network):
Local area network is digital communication system in which you can connect a large
number of computers in a limited geographical area. Limited geographical area means less than 1
Km across.
A wide area network is digital communication system; it connects the computer with a
great distance, typically across cities or even countries. E.g. ATM of bank
MAN (Metropolitan Area Network)
MAN is a network that interconnects user with computer resources in geographical area
or region, larger than that covered by a large LAN but the smaller than the area covered by a
WAN.
Connecting LAN to other Network:
There are some devices that connect LAN to other networks, these devices called special
purpose devices.
Routers
Bridges
Gateways
Modems

Network Topologies:
There are four types of network topologies.
Star
Ring
Bus
Point-to-Point / Peer-to-Peer
It is designed with each node connected directly to a central network called Hub. Data on star
network passes through the Hub before continuing to its destination. If any of the local
computers fail, the remaining portion of the star network is unaffected. Multiple messages sent
simultaneously on star.
What is Ring Topology?
No server is required. In ring topology, computers are connected on a single circle of cable. It is
more reliable than the star network because communication is not dependent on a single host
computer.
What is Bus Topology?
No server is required for bus topology, in this topology the data or messages sent to one
computer to another computer directly, if any nodes goes down the rest of the network won’t
affected.
What is P2P Topology?
This type of topology is less expensive, have limited connectivity and used to connect
two LANs to form a WAN.
Types of Networking Protocol:
There is two types of networking protocols, these are
Ethernet protocol
Token Ring Protocol
What is Ethernet Protocol?
This type of protocol checks the shared connection before transmitting the message is it
in use or not.
What is Token Ring Protocol?
This protocol passes the special message through network called a Token. When any
computer receives the token has permission to send that packet or token to other one.
Types of Communication Channels:-
Wire (twisted pair, coaxial cable, optical fiber)
Wireless (laser, radio, cellular, satellite)
Key characteristics of these channel is Bandwidth
What is Bandwidth?
Capacity of carrying the data of communication and it is measured in bits e.g. (bps, kb/s,
Mb/s)
What is Internet?
Internet enables to share information with others from all over the world; it is very less
expensive utility and accessible to every humankind. Internet is accessible from every where of
the world and this is fastest growing technology. Internet is for public any one from any where
can access and do anything and intranet is for private, limited access.
What is TCP/IP?
TCP/IP stands for Transmission Control Protocol/Internet Protocol. TCP breaks down the
message to sent over the internet into packets, when message reached to its destination TCP
convert it to its original form.
Tools that are Available on the Internet:
Electronic mail (POP, SMTP) Post Office Protocol, Simple Mail Transfer Protocol
Instant messaging (MSN, YAHOO, ICQ, AOL)
Remote login (Telnet)
File transfer protocol (FTP)
Network news (nntp) Network News Transfer Protocol

In this scheme, pixels are used to simulate a color that is not present in the platelet.
What is Aliasing?
Computer screen consist of square-ish pixels & when we draw a single line, they don’t
show the single line show pixels in staircase this is aliasing. Aliasing can be managed by
reducing the size of pixel.
What is Anti – Aliasing?
OnClick
onDblClick
onMouseOver
onMouseDown
onFocus
OnBlur
onReset

Integrity refers to maintaining the correctness and consistency of the data. Integrity can
compromised in many ways like (Typing errors, Transmission errors, Bugs, Viruses)
Correctness Free from all errors
Consistency No conflicts among related data
Types of Integrity:
There are four types of integrity
Type Integrity (used to specify the data type e.g. credit card 12 number)
Limit Integrity (used to limiting the data to specified ranges e.g. age of person shouldn’t be -ve)
Referential Integrity (used for reference of data that exist in the database)
Physical Integrity (used for backup)

Database Management System is SW that operates a database, DBMS take care of the
storage, retrieval, and the management of the data in large sets on a database. DBMS can add,
delete, modify, make queries and produce reports and also summarize the required contents.
Database is a collection of data that is organized in such a fashion that the computer can quickly
search for desired data. Database consists of a collection of interrelated computer files.
What is Relational Database?
Database consists of two or more related tables called relational databases.

Question No: 30 ( Marks: 3 )
How a designer makes Structured Design? Answer: Structured Design: Materials and member
type, size, and configuration to carry loads
in a safe and serviceable fashion.
In general, structural design implies the engineering of stationary objects such as buildings
and bridges, or objects that may be mobile but have a rigid shape such as ship hulls and aircraft
frames tructural design involves at least five distinct phases of work, project requirements,
materials, structural scheme, analysis, and design It is insufficient in most cases, for the designer
to consider a solution, a design. He should evaluate several alternate designs and choose the best
in the sense of maximizing such technical objectives as efficiency, reliability, and maintainability
while satisfying such design constraints as memory size and response time.
What is Turing machine? Who invented it and also explain how a Turing test is conducted?
Answer: A Turing machine is a theoretical device that manipulates symbols contained on a
strip of tape. Despite its simplicity, a Turing machine can be adapted to simulate the logic of
any computer algorithm, and is particularly useful in explaining the functions of a CPU inside
of a computer. The "Turing" machine was designed by Alan Turing in 1937.
The Turing test is a proposal for a test of a machine's ability to demonstrate intelligence. It
proceeds as follows a human judge engages in a natural language conversation with one
human and one machine, each of which tries to appear human. All participants are placed in
isolated locations. If the judge cannot reliably tell the machine from the human, the machine
is said to have passed the test. In order to test the machine's intelligence rather than its ability
to render words into audio, the conversation is limited to a text-only channel such as a
computer keyboard and screen. If a computer pass the test ,we can say that a machine can think.
Question No: 32 ( Marks: 5 )
What are JavaScript literal and what are its types?
Answer: The raw data that make up the root of data types are called "literals." These are, in
effect, literally what they represent themselves to be. Numbers, strings, and Boolean values
make up the core set of literals in JavaScript. Little mystery exists with literals, but important
differences exist between them. In JavaScript, data types include strings, which are simply
quoted characters, numbers, Boolean, Objects and even a type which has no value at all, Null.
Since JavaScript is a loosely typed language, you don't necessarily need to know what type of
data every value is (although it certainly helps).
Every piece of data in these categories is known as a value. When a value is referred to
outright in a statement, it is called a literal value. For the same reason people are identified by
names as opposed to "human" or "person", literal values can be named in order to make
repeated reference to them practical, efficient and readable. These names are called variables.
Literals can be of several types. Some of them are:
Array Literals
Boolean Literals
Floating-Point Literals
Integers
Object Literals
String Literals
Define URL
URL(Uniform resource locator)
URL (Uniform Resource Locator, previously Universal Resource Locator) - is the
address of a file (resource) accessible on the Internet. The type of file or
resource depends on the Internet application protocol.

Question No: 30 ( Marks: 3 )
How a designer makes Structured Design?
Structured Design is known as a Top-down design.
The designed first conceives about the High level design and then further
designs the details of the high level design components and it goes on and on.
Making small changes in the functionality of the systems sometimes leads to
major re-design exercise. Structured design separates the functionality from
programs data and that’s why program’s designed by this methodology are
difficult to maintain.
Question No: 31 ( Marks: 5 )
Why microprocessor uses the binary number system and not the decimal or any
other number system?
The processor is the logic of a computer and functions comparably to a human central nervous
system, directing signals from one component to another and enabling everything to happen. A
microprocessor is made from miniaturized transistors and other circuit elements on a single
semiconductor integrated circuit (IC) . These are made up of semiconductor and silicon.
Microprocessors are composed of components which has only two states either 0 or 1. Binary
number system is also composed of these two states. Microprocessor till today only understand
the machine language and machine language is only based on binary number system. Even
today’s 64 bit microprocessors are also based on this technology.
Question No: 32 ( Marks: 5 )

• Each column of those tables can contain only a single type of data (contrast this
with spreadsheet columns!)
• Table rows are called records; row elements are called fields
• A relational database stores all its data inside tables, and nowhere else
• All operations on data are done on those tables or those that are generated by table
operations
• Tables, tables, and nothing but tables!
