What is the process and project matrics? Explain 3 P's in software engineering.

-

Solution:- 

a) Process Metrics

These are the metrics pertaining to the Process Quality. They measure efficiency and effectiveness of various processes.

b) Project Metrics

These are the metrics pertaining to the Project Quality. They measure defects, cost, schedule, productivity and estimation of various project resources and deliverables.found in acceptance)/ total no of testing defects) x 100

THE THREE Ps:-

The People

• People factor is very much important in the process of software development.

• There are following areas for software people like, recruiting, selection performance management, training, compensation, career development, organization and work design, and team/culture development.

• Organizations achieve high levels of maturity in the people management area.

The Product

• Before a project can be planned, product objectives and scope should be established, alternative solutions should be considered and technical and management constraints should be identified.

• Without this information, it is impossible to define reasonable estimates of the

cost, an effective assessment of risk, a realistic breakdown of project tasks, or a manageable project schedule.

• Objectives identify the overall goals for the product without considering how these goals will be achieved. Scope identifies the primary data, functions and behaviors that characterize the product.

• Once the product objectives and scope are understood, alternative solutions are considered. From the available various alternatives, managers and practitioners select a "best" approach.

The Process

• A software process provides the framework from which a comprehensive plan for software development can be established.

• A small number of frame-work activities are applicable to all software projects, regardless of their size or complexity.

• A number of different tasks, milestones, work products and quality assurance points enable the framework activities to be adapted to the characteristics of the software project and the requirements of the project team.

• Finally, umbrella activities such as software quality assurance, software configuration management, and measurement overlay the process model.

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.

Image
  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. ...
