Difference Between Blackbox and Whitebox Testing
Parameter
|
Black Box Testing
|
White Box Testing
|
Definition
|
It is a Software Testing Technique that examines the functionality of an Application without peering into its working or coding.
|
It is a Software Testing Technique to test internal structure and working of an Application Software.
|
Technique Applied in
|
This Technique Applied in Unit, Integration, System and Acceptance levels of Software Testing Process.
|
This Technique Applied in Unit, Integration and system levels of Software Testing Process.
|
Test Procedures
|
For Black box Testing Specific knowledge of the application's coding/internal structure and programming in general is not required.
|
For White box Testing Specific knowledge of the application's coding/internal structure and programming is required. |
Difference Between MAC and IP address
Parameter
|
MAC Address
|
IP Address
|
Acronym for
|
media access control address
|
Internet Protocol Address
|
Used for
|
It is a unique identifier that is assigned to network interfaces for communicating on the physical network segments.
|
It is a numerical value that is assigned to all the participating devices in a network. i.e. Servers, Computers, Printers, WAP, Laptops etc.
|
Provided BY
|
It is generally provided by the manufacturer of the NIC cards and is stored in its hardware.
| |
Length
|
It is 48 bit address which contains 6 groups of 2 hexadecimal digits, separated by either hyphens (-) or colons (:)
E.g. 00:FF:FF:AB:BB:AA
Or 00-FF-FF-AB-BB-AA
|
IPv4 uses 32 bit address in dotted notations, whereas IPv6 Uses 128 bit address in hexadecimal notations.
e.g. IPv4 192.168.1.1
IPv6 FFFE:F200:3204:0B00: 0122:4555:8001:AB00 |

Difference Between OSI and TCP/IP Reference Models
Parameter
|
OSI Reference Model
|
TCP/IP Model
|
Clarification between Services, Interfaces and Protocols
|
OSI Model clearly distinguishes between Services, Interfaces and Protocols. Each layer performs some services to upper layers, layer interfaces tells the processes above it how to access it, and different protocols are used by different layers as per their needs until a job is not finished.
|
TCP/IP model does not clearly distinguish between Services, Interfaces and Protocols.
|
Protocol Biasing
|
This model is not biased for a particular set of protocols and was developed before corresponding protocols invention.
|
This Model was developed after inventing corresponding protocols and just was description of existing protocols.
|
Layers
|
It is a Seven Layered Model. Which are as follows :
a) Physical Layer
b) Data Link Layer
c) Network Layer
d) Transport Layer
e) Session Layer
f) Presentation Layer
g) Application Layer
|
It is a 4 Layered Model. Which are as follows:
a) Subnet Layer
b) Internet Layer
c) Transport layer
d) Application Layer

Difference Between Synchronous TDM and Statistical TDM
Parameter
|
Synchronous TDM
|
Statistical TDM
|
Working
|
In Synchronous TDM data flow of each input connection is divided into units and each input occupies one output time slot.
|
In Statistical TDM slots are allotted dynamically. i.e. input line is given slots in output frame if and only if it has data to send.
|
No. of Slots
|
In Synchronous TDM no. of slots in each frame are equal to no. of input lines.
|
In Statistical TDM, No. of slots in each frame are less than the no. of input lines.
|
Buffers
|
Buffering is not done, frame is sent after a particular interval of time whether someone has data to send or not.
|
Buffering is done and only those inputs are given slots in output frame whose buffer contains data to send.
|
Addressing
|
Slots in Synchronous TDM carry data only and there is no need of addressing. Synchronization and pre assigned relationships between input and outputs that serve as an address.
|
Slots in Statistical TDM contain both data and address of the destination. |
