Explain. (i). Components-level design elements (ii). Deployment level design elements. With respect to design model.

-

 Solution:-

Component-level design elements:

1. Component-level design defines data structures for all local data objects and algorithmic detail for all processing that occurs within a component and an interface that allows access to all component operations .

2. Within the context of object-oriented software engineering, a component is represented in UML diagrammatic form. 

3. The design details of a component can be modeled at many different levels of abstraction. A UML activity diagram can be used to represent processing logic.

4. Detailed procedural flow for a component can be represented using either pseudo code or some other diagrammatic form. 

5. Algorithmic structure follows the rules established for structured programming. Data structures, selected based on the nature of the data objects to be processed are usually modeled using pseudo code or the programming language to be used for implementation. 

Deployment-level design elements: 

1. indicate how software functionality and subsystems will be allocated within the physical computing environment that will support the software. 

2. During design, a UML deployment diagram is developed and then refined. Each subsystem would be elaborated to indicate the components that it implements. 

3. The deployment diagram shows the computing environment but does not explicitly indicate configuration details. 

4. These details are provided when the deployment diagram is revisited in instance form during the latter stages of design or as construction begins. Each instance of the deployment (a specific, named hardware configuration) is identified.

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. ...
