TCP - Transfer Control Protocol is:a. Reliableb. Connection oriented.c. Acknowledgement

UDP - User Datagram Protocol is none of the above.

Public IP are the IP that can be accessed by every onetime very user has the access to this IP's e.g. yahoo.com, google.com etc are the pubic IPs.

Private IP's are the IP that are accessed by every one, I.e. they are excessively owned by an organization, only the user of that organization has the access to this IP's.

Ranges of private IP address are

Class A 10.0.0.1 to 10.255.255.254

Class B 172.16.0.1 to 172.31.255.254

Class C 192.0.0.1 to 192.255.255.254

Excluding imps are public IP's.

Remote Access services (RAS) on Wide Area Network (WAN) Connection.

Subnet mask is use to isolate the network ID and Host ID. e.g. - if an IP is 192.168.0.1 then the default subnet is 255.255.255.0 because it is a C Class Address C Class Add. Have three network octate and one host octate i.e.

Network ID: 192.168.0.0

Host ID : 0.0.0.1

Terminal Services is a component of Microsoft Windows operating systems (both client and server versions) that allows a user to access applications or data stored on a remote computer over a network connection. Terminal Services is Microsoft's take on server centric computing, which allows individual users to access network resources easily.

DNS stands for Domain Name System. DNS is used to IP address to name resolution.

Open System Interconnection is an ISO standard for worldwide communication that defines a networking framework for implementing protocols in seven layers. The seven layers are:

1) Application Layer

2) Presentation Layer

3) Session Layer

4) Transport Layer

5) Network Layer

6) Data Link Layer

7) Physical Layer

DHCP Is A Server Service. Before Installation of DHCP, We should install DNS Active Directory in Server Only Assigning IP Address to Clients.

Protocol - Set of rules and regulation, which are necessary for communication the data between one or more computers.

TCP/IP- In same manner Transmission control Protocol and Internet Protocol are the group of the protocol, which is supported by various operating system (windows, Linux, sun, Macintosh, Polaris etc.) for communicating data frequently without interruption.

These protocols are follows IEEE standards.

void Mult_Matrix(matrix A, matrix B, matrix C){int i, j, k;for ( i = 1; i < N; i++)for ( j = 1; j < N; j++ ){C[i][j] = 0;for ( k = 0; k < N; k++ )C[i][j] = A[i][j]*B[k][j];}return;}

The time complexity of matrix multiplication is O (N^3)

The null pointer is a special C++ pointer value that can be any pointer does not point anywhere. It is the constant NULL form stlib.h

The goal is completely fill the distance array so that for each vertex v, the value of distance[v] is the weight of the shortest path from start to v.

An abstract class may have fields and some implemented methods. An interface has no implementation, only constants and method declarations.

It is a four-step process consisting of (a) IP request, (b) IP offer, © IP selection, and (d) acknowledgement.

The 169.254.*.* netmask is assigned to Windows machines running 98/2000/XP if the DHCP server is not available. The name for the technology is APIPA (Automatic Private Internet Protocol Addressing).

The server should authorize first with the Active Directory.

Windows 2000 Servers have PAP, SPAP, CHAP, MS-CHAP and EAP.

NWLink (Novell), NetBEUI, AppleTalk (Apple).
