What do you mean by testing strategies?

-

 Solution:-

A strategy for software testing may also be viewed in the context of the spiral. 

Unit testing begins at the vortex of the spiral and concentrates on each unit (e.g., component,class, or Web App content object) of the software as implemented in source code.

Testing progresses by moving outward along the spiral to integration testing, where the focus is on design and the construction of the software architecture. 

Taking another turn outward on the spiral, which encounters validation testing, where requirements established as part of requirements modeling are validated against the software that has been constructed.

 Finally, system testing, where the software and other system elements are tested as a whole. To test computer software, spiral out in a clockwise direction along streamlines that broaden the scope of testing with each turn.


1. Testing begins at the component level and works "outward" toward the integration of
the entire computer-based system.
2. Different testing techniques are appropriate at different points in time.
3. Testing is conducted by the developer of the software and (for large projects) an independent test group.
4. Testing and debugging are different activities, but debugging must be accommodated
in any testing strategy.
5.A strategy for software testing must accommodate low-level tests that are necessary
to verify that a small source code segment has been correctly implemented as well as high-level tests that validate major system functions against customer requirements.

State the functions of Hub, Repeater, Bridge and Router.

-
  1)Hub : Hub connects all nodes in star topology. Hub is broadcasting device. It sends packets to all nodes in the network. It works at Physical Layer of OSI model. 2) Repeater : Repeaters are used to take the distorted, weak and corrupt input signal and regenerate this signal at its output. It ensures that the signals are not distorted or weak before it reaches the destination. It increases the signal strength. 3)Bridge : A bridge device filters data traffic at a network boundary. Bridges reduces the amount of traffic on a LAN by dividing it into two segments. It inspects incoming traffic and decides whether to forward or discard it. It sends packets between two networks of same type. 4)Router : Router chooses the best path for packet forwarding. Router read complex network address in packet. It works at Network Layer of OSI model Efficiently direct packets from one network to another, reducing excessive traffic. Join neighbouring or distant network Connect dissimilar networks. P...

Describe the OSI model with neat diagram.

  Solution:- OSI model (open system interconnection) model was developed by ISO (international standard organization) Function of OSI model: i. It provides way to understand how internetwork operates.  ii. It gives guideline for creating network standard. OSI model has 7 layers as shown in the figure.  OSI model has following 7 layers as Physical layer, data link layer, Network layer, Transport layer, session layer, presentation layer, application layer.  1. Physical layer: 1. It co-ordinates the functions required to transmit bit stream over physical medium. 2. It deals with mechanical and electrical specifications of interface and transmission medium. Functions of physical layer are: Physical characteristics of interfaces and media.  Representation of bits: Data rate (transmission rate).  Synchronization of bits.  Line configuration: Point to point or multipoint configuration should be used.  2. Data link layer: 1. It is responsible for transmit...

Explain Database languages.

-
Data Definition Language The language is used to create database, tables, alter them, etc. With this, you can also rename the database, or drop them. It specifies the database schema. The DDL statements include − CREATE :  Create new database, table, etc. ALTER : Alter existing database, table, etc. DROP : Drop the database RENAME : Set a new name for the table. Data Manipulation Language The language used to manipulate the database like inserting data, updating table, retrieving record  from a table, etc. is known as Data Manipulation Language − SELECT : Retrieve data from the database INSERT : Insert data UPDATE :  Update data DELETE : Delete all records Data Control Language Grant privilege to a user using the GRANT statement. In the same way, revoke the privilege using the REVOKE statement. Both of these statements come under the Data Control Language (DCL). − GRANT : Give privilege to access the database. REVOKE:  Take back the privilege to access the database. ...
