State and describe various core principles of software engineering.

 Solution:-

The First Principle: The Reason It All Exists A software system exists for one reason: To provide value to its users. All decisions should be made with this in mind. Before specifying a system requirement, before noting a piece of system functionality, before determining the hardware platforms or development processes, ask yourself questions such as: "Does this add real VALUE to the system?" If the answer is "no", don't do it. All other principles support this one.

The Second Principle: Keep it Simple and Stupid Software design is not haphazard process. There are many factors to consider in any design efforts. All design should be as simple as possible, but no simpler. This facilitates having a more easily understood, and easily maintained system. This is not to say that features, even internal features, should be discarded in the name of simplicity.

The Third Principle: Maintain the Vision A Clear vision is essential to the success of a software project. Without that A project almost unfailingly ends up being ―of two minds about itself. Without conceptual integrity, a system threatens to become a patchwork of incompatible designs, held together.

The Fourth Principle: What You Produce, Others Will Consume Seldom is an industrial strength software system constructed and used in vacuum. In some way or other, someone else will use, maintain, document or otherwise depend on being able to understand your system. So always specify design and implement knowing someone else will have to understand what you are doing.

The Fifth Principle: Be Open to the Future While implementing a system a developer of a system shall always consider for the scope of improvement in a given system, by virtue of which there will be continuous upgrading in a given system and the system can be timely reviewed. As a result of this one can have better and improved system at the end of all iterations.

The Six Principle: Plan Ahead For Reuse While implementing a system the development team can think about having a module which are already developed in a similar kind of system, resulting in a less time of development and as these modules are reused very little time can be spend on the

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. ...
