Explain inspection and walk through.

-

 Solution:-

  • Inspection:

i. Inspections are the most formal type of reviews.

ii. They are highly structured and require training for each participant.

iii. Inspections are different from peer reviews and walkthroughs in that the person who presents the code, the presenter or reader isn't the original programmer.

iv. These forces someone else to learn and understand the material being presented, potentially giving a different slant and interpretation at the inspection meeting.

v. The other participants are called inspectors.

vi. Each is tasked with reviewing the code from a different perspective, such as a User, a tester, or a product support person.

vii. This helps bring different views of the product under review and very often Identifies different bugs.

viii. One inspector is even tasked with reviewing the code backward that is, from the end to the beginning to make sure that the material is covered evenly and completely.

  • Walkthrough:

i. Walkthroughs are the next step up in formality from peer reviews.

ii. In a walkthrough, the programmer who wrote the code formally presents (Walks through) it to a small group of five or so other programmers and testers.

iii. The reviewers should receive copies of the software in advance of the review so they can examine it and write comments and questions that they want to ask at the review.

iv. Having at least one senior programmer as a reviewer is very important.

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. ...
