What are Difference between RIP, IGRP, EIGRP and OSPF Routing Protocol?

                 
1.    RIP-:
o    RIP Stands For Routing Information protocol
o    It Is a Industry standard Dynamic Routing Protocol
o    IT Is not a More Intelligent Dynamic Routing Protocol
o    It Is Basically Use For Smaller Size Organization
o    It Support Maximum 15 Routers in the Network. 16 Router Is Unreachable
o    It is denoted By R in Routing Table.
o    It’s Administrative Distance Is 120.
o    In RIP Routing protocol We cannot create A Separate Administrative boundary in The Network.
o    It Calculate the Metric In Terms Of Hop Count From source Network to destination Network. Lower the Hop count that Is the Best route For That Particular Network.
o    It works on Bellman Ford algorithm
o    RIPV.1 Do Not Support VLSM
o    RIPV.2 Support VLSM


2.    IGRP-:
o    IGRP Stands For Interior Gateway Routing protocol
o    It Is a Cisco standard Routing protocol
o    It IS A More Intelligent Routing Protocol Than RIP
o    It Is Basically use For Medium To Larger size organization in The Network
o    It Is denoted by I in Routing Table
o    It supports  Maximum 255 routers in The Network
o    It’s administrative Distance Is 100
o    In IGRP Routing protocol We Can Create a separate Administrative Boundary in The Network with the Help Of autonomous System No.
o    It Calculates the Metric in terms Of bandwidth And Delay. It Is Also Called Composite Metric.
o    It works On Bellman ford Algorithm
o    IGRP Do Not Support VLSM

3.    EIGRP-:
o    EIGRP Stands For Enhanced Interior Gateway Routing protocol
o    It Is a Cisco standard routing protocol
o    It Is a More Intelligent routing protocol Than RIP And IGRP
o    It Is Basically Use For Medium to Lager Size Organization in the network.
o    It supports Maximum 255 Routers in The Network
o    It’s Administrative distance Is 90
o    It calculates the Metric In Terms Of Bandwidth And delay
o    EIGRP Works on DUAL(Diffusing Update Algorithm) Algorithm
o    EIGRP is denoted by D in Routing Table.
o    EIGRP Supports VLSM
o    EIGRP Creates three table In the Router-  
1.     
1.    Neighbor Table
2.    Topology Table
3.    Routing Table

    4. OSPF-:
·         
o    OSPF stands For Open shortest path First
o    It Is A Industry standard Routing protocol
o    It supports Unlimited router in the Network
o    It Is Denoted By O in routing Table
o    It’s Administrative distance is 110
o    It Is basically Use For Larger Size Organization in The Network
o    In OSPF Routing protocol We Can Create a separate administrative boundary in the Network through Area No. within The same area all of The routers Are exchanging The Route information From Neighbor router in the network.
o    It Calculates the Metric in terms of Bandwidth
o    OSPF works on DIJKSTRA Algorithm
o    It Is a More Intelligent routing protocol
o    OSPF Supports VLSM
o    OSPF Routing protocol Creates three Table in the router—
1.    Neighbor Table
2.    Database table
3.    Routing Table


What are the Timer of RIP, IGRP, EIGRP and OSPF Routing Protocol?

              
RIP Timer:
1.    Update Timer— 30 Second
2.    Hold down Timer—180 Second
3.    Invalid Timer—180 Second
4.    Flush Timer—240 Second

IGRP Timer:
1.    Update timer—90 Second
2.    Hold Down timer—280 Second
3.    Invalid timer—270 Second
4.    Flush Timer—630 Second

EIGRP Timer:
1.    Hello timer—5 Second (Point-to-Point), 60 Second (Multi Point)
2.    Hold Down timer—15 Second (Point-to-Point), 180 Second (Multi Point)
3.    Active Timer (It is a configurable and it is used for overcome stuck in activity (SIA)

OSPF timer:
1.    Hello timer—10 Second (Broadcast and Point-to-Point), 30 Second (Non-Broadcast, Point-to-Multipoint)
2.    Dead timer—40 Second (Broadcast and Point-to-Point), 120 Second (Non-Broadcast, Point-to-Multipoint)

Overview of FAT, HPFS, and NTFS File Systems Summary This article explains the differences between FAT, HPFS, and NTFS under Windows NT, and their advantages and disadvantages. It is divided into the following sections: FAT Overview HPFS Overview NTFS Overview NOTE: HPFS is only supported under Windows NT versions 3.1, 3.5, and 3.51. Windows NT 4.0 does not support and cannot access HPFS partitions. Also, the FAT32 file system is only supported in the Windows 98/95 and Windows 2000. More Information FAT OVERVIEW FAT is by far the most simplistic of the file systems supported by Windows NT. The FAT file system is characterized by the file allocation table (FAT), which is really a table that resides at the very "top" of the volume. To protect the volume, two copies of the FAT are kept in case one becomes damaged. In addition, the FAT tables and the root directory must be stored in a fixed location so that the system's boot files can be

The Version API Helper functions are used to determine the version of the operating system that is currently running. For more information, see Getting the System Version. The following table summarizes the most recent operating system version numbers. Operating system Version number Windows 10 10.0* Windows Server 2016 10.0* Windows 8.1 6.3* Windows Server 2012 R2 6.3* Windows 8 6.2 Windows Server 2012 6.2 Windows 7 6.1 Windows Server 2008 R2 6.1 Windows Server 2008 6.0 Windows Vista 6.0 Windows Server 2003 R2 5.2 Windows Server 2003 5.2 Windows XP 64-Bit Edition 5.2 Windows XP 5.1 Windows 2000 5.0 *  For applications that have been manifested for Windows 8.1 or Windows 10. Applications not manifested for Windows 8.1 or Windows 10 will return the Windows 8 OS version value (6.2). To manifest your applications for Windows 8.1 or Windows 10. Identifying the current operating system is usually not the best way to determine whether a particular operating sys
