What is a network ?

A computer network is defined as a group of computers which share the resources such as software, hardware and other computing resources like operating system, database, and others. Inside a network, computers are connected to each other through a communication channel. Apart from the shared resources, each computer has its own set of resource.

Client and Server

A server is responsible to have all the resources that can be shared. These resources form the services provided by the server like database service, printing service, and the like.

Clients are systems that access the shared resources that lie at the server.

How network works ?

The computers and the shared resources are connected to the network via network bus. When a computer transmits data for others, it is transmitted in the form of data groups called data packets. Each computer on the network acts as the receiver of the data packet.

The packet contains the addresses of the sender and the receiver. Based on the address, the actual recipient receives the packet. The other computers reject the packet since the address does not matches with their own address.

The sender’s address is included in order that the recipient should know the address so that response can be sent to the correct computer.

Network protocols

Every network functions according to the set of pre defined rules. These rules underline the communication which takes place between the computing systems in the network.

The rules are called network protocols.

The communication should take place according to the rules otherwise the networked systems can not communicate with each other.

Network security

Similar to an individual computer, the network also has its own security mechanism to prevent unauthorized access to the network and its components and data. Only the networked computers are authorized and allowed access.

This program should be a short piece of code that prints all of the positive integers from 1 to 100 as described more fully below. the program may contain multiple methods, and if using an oo language, should be contained within a single class or object. the program should be designed so that it begins execution when invoked through whichever mechanism is most common for the implementation language. â–ş print out all positive integers from 1 to 100, inclusive and in order. â–ş print messages to standard output, matching the sample output below. â–ş in the output, state whether the each integer is 'odd' or 'even' in the output. â–ş if the number is divisible by three, instead of stating that the number is odd or even, state that the number is 'divisible by three'. â–ş if the number is divisible by both two and three, instead of saying that the number is odd, even or divisible by three; state that the number is 'divisible by two and three'. â–ş design the logic of the loop to be as efficient as possible, using the minimal number of operations to perform the required logic. sample output the number '1' is odd. the number '2' is even. the number '3' is divisible by three. the number '6' is divisible by two and three.
