What is computer networking, how to create one?

Computer networking is formed when two or more computers are connected using network cables and configured those using a network operating system. Computer networking is very important concept and which is backbone of today’s internet. We can use computer networking to communicate with each other and share different types of documents and other media such …

Difference between connection oriented and connectionless service

Network layers can offer two different types of service to the layers above them. They are connection oriented and connectionless. Connection  oriented service is modeled after the telephone system. To talk to someone, we pick up the phone, dial the number, talk, and then we hang up. Similarly, to use a connection oriented network service, …

What is interface and its services in layered architecture of computer network?

The function of each layer in computer networking architecture is to provide services to the layer above it. The active elements in each layer are often called entities. An entity can be a software entity (such as a process), or a hardware entity (such as an intelligent I/O chip). Entries in the same layer on …

Computer networking Protocols and their layered hierarchy

To reduce the networking and it’s design complexity most of the networks are organized into series of layered structure. At each important stage of transferring data from one machine to another machine in computer networking there is a layered concept. This layered structure is just to fulfill the successful completion of the sending and receiving …

What is Internetworking

Internetworking is the process of connecting a computer network with many other networks using special machines called gateways or routers. This type of network provides a common method of routing packets between the different networks. The entire system of interconnected networks is called an internetwork  or internet. Internetworking is the art & science of connecting …

5 goals for implementing computer networks in companies

There are many organizations have a substantial number of computers in operation which are often located far apart. For example, a company with many factories may have computers at each location to keep track of inventories, monitor productivity and for doing local payroll. Initially these computers may have worked in isolation from other computers, but …

What is name server (DNS) and its functionality over the Internet?

Network computer users generally prefers to use domain names instead of IP addresses. However, computers use 32-bit IP addresses to communicate with other computers. To ensure successful internetwork communication between the programs and users, we need a fast and reliable method of translating between host names to IP addresses and vice versa. For this reason, …

What is transport layer and what are transport layer protocols?

Transport layer is the heart of the whole protocol hierarchy. Applications will exchange data with TCP/IP transport layer to communicate with Internet. The task of the transport layer is to provide cost effective and reliable data transport from source computer to destination computer, independent of physical network used. Transport layer consists of Transport Control Protocol …

What is an Internet protocol (IP) and its importance in data delivery system.

TCP/IP protocol suite consists of Internet protocol which is used for data delivery over network. Remaining protocols TCP, UDP and ICMP in the TCP/IP protocol suite uses the Internet protocol to deliver the data from one host to another host. This associates with the network layer of OSI reference model. The network layer is heart …

What is the protocol stack and Explain by taking TCP/IP suite as example?

Protocol stack can be defined as any combination of network layers and their associated protocols. An ISO/OSI network model divides network into layers. Each layer performs specific function.  OSI model associates protocols that define the layer’s functionality with each layer. OSI model stacks protocols on top of each other. So it is protocol stack. TCP/IP …
