Write a short note on SLIP and PPP.

-

Solution :-

SLIP

1. Serial Line Protocol is an encapsulation of the Internet Protocol designed to work over serial ports and modem connections.

2. This packet-framing protocol and defines a sequence of bytes that frame IP packets on a serial line.

3. SLIP is commonly used for point-to-point serial connections running TCP/IP

4. It is designed to transmit signals over a serial connection and has very low overhead.

5. SLIP is serial line internet protocol

6. SLIP does not perform error detection and correction.

7. SLIP does not provide any authentication.

8. SLIP is not approved internet standard.

9. SLIP supports static IP address assignment

PPP 

1. PPP is point to point protocol.

2. It is a much more developed protocol than SLIP(which is why it is replacing it).

3. It transfers additional data, better suited to data transmission over the Internet(the addition of data in a frame is mainly due to the increase in bandwidth).

4. PPP perform error detection 

5. PPP provides authentication and security. 

6. PPP is approved internet standard. 

7. PPP supports IP and other protocols. 

8. PPP supports Dynamic IP address assignment 

9. PPP is a collection of three protocols: 

  • A datagram encapsulation protocol 
  • LCP i.e. Link Control Protocol, enabling testing and communication configuration. A
  • Acollection of NCPs i.e. Network Control Protocols allowing integration control of PPP within the protocols of the upper layers.

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. ...
