What is a Distributed Computing System?

A Distributed computing is a model of computation that is firmly related to Distributed Systems, refers to as multiple computer systems located at different places linked together over a network and use to solve higher level computation without having to use an expensive supercomputer.

What is protocol and its types?

Protocol Definition: It is a digital language through which we communicate with others on the Internet. protocol meaning is that it a set of mutually accepted and implemented rules at both ends of the communications channel for the proper exchange of information. By adopting these rules, two devices can communicate with each other and can interchange information. We can't even think of using the Internet without Protocols. Each protocol is defined in different terms and different use with unique name.

What is LAN (Local Area Network)

what is lan: It actually stands for local area network. A network is a group of computers and other devices connected together so they can pass information back and forth. The local area network (LAN) is a network which is designed to operate over a small physical area such as an office, factory or a group of buildings. LANs are very widely used in a variety of applications.

What is Router

What is router: Router is a network layer (Layer 3) of the OSI reference model device that means it can connect multiple computer networks via wired or wireless connections. Network router can receive, analyze, perform the traffic directing functions and forwards data packet from one network to its destination node.

What is Ethernet?

Ethernet (pronounced "eether net") is a computer network technology which is used in different area networks like LAN, MAN, WAN. Ethernet connecting computers together with cable so the computers can share information. Within each main branch of the network, "Ethernet" can connect up to 1,024 personal computers and workstations.

What is Hub | Definition of Hub | Meaning of Hub

What is Hub: Another name of Hub is Ethernet Hub, Repeater Hub, Active Hub and Network Hub. Basically, it is a similar to switch but are not as "smart", Hub Definition and Meaning : hub in computer network is used for connecting multiple computers or segments of a LAN. Normally, it is used for Peer to Peer small Home Network. LAN Hub receive data packets (frames) through one port and broadcasts them through all other ports, so that all other computers or other network devices can see all packets.

What is Cluster Computing?

Cluster computing or High-Performance computing frameworks is a form of computing in which bunch of computers (often called nodes) that are connected through a LAN (local area network) so that, they behave like a single machine. A computer cluster help to solve complex operations more efficiently with much faster processing speed, better data integrity than a single computer and they only used for mission-critical applications.

What is HTTP (Hypertext Transfer Protocol)?

What is http: HTTP full form HyperText Transfer Protocol used mainly to access data on the World Wide Web. HTTP is a Server and Client communication Protocol, which is primarily set of rules for formating and transferring webpage data (text, images, video and Multimedia files) over the world wide web. This is the Protocol used to create communication between Web Servers and Web Users. HTTP is an application layer Protocol that works on the top of the TCP/IP suite of Protocols.

What is OLE (object linking and embedding)?

OLE definition is that, OLE (pronounced as oh-leh) was originally mean as 'object linking and embedding', it is a Microsoft compound document technology based on Component Object Model (COM), It is introduced into Microsoft Windows 3.1. 'OLE (object linking and embedding)' gives all Windows applications a standard way to create compound documents that create objects within one microsoft application and embed them into other document. OLE object meaning is graphic,spreadsheet,msword, etc. that can be embedded into a document called the "container application." If the object allowed to be edited, the application associated with it is called "server application".

What is Parallel Computing?

In computers, parallel computing is closely related to parallel processing (or concurrent computing). It is the form of computation in which concomitant ("in parallel") use of multiple CPUs that is carried out simultaneously with shared-memory systems to solving a supercomputing computational problem. Parallelism is the process of large computations, which can be broken down into multiple processors that can process independently and whose results combined upon completion. Parallelism has long employed in high-performance supercomputing.

History of computer | Generation of Computer

Each generation of computer is characterized by a major technological development that fundamentally changed the way computers operate, resulting in increasingly smaller, cheaper, more powerful and more efficient and reliable devices.

Service of a man is the service of God.
