Network convergence is known as having multiple communication mediums within a single network. Now here in this image, you can see there is a different kind of modules or tech or communication medium within a single network connection. Before going through the content, I would like to introduce you to the learning platform called Udacity,…
In this very article we will be discussing the different types of unguided or wireless medias for communications. Please comment down if you have any queries. Microwave System Microwave systems transmit high-speed radio signals in a line of sight path between relay stations i.e transmission from one antenna to another usually placed on top of…
A threat to a computing system is a set of circumstances that has the potential to cause loss or harm. It is a potential violation of security, means that it is a possible danger that might exploit the vulnerability. The attack is an assault on system security that derives from an intelligent threat, i.e. attack…
Let’s discuss what is Computer Security & Information Security and why they are important. First of all Information security means protecting information and information systems from unauthorized access, use, modification, or destruction. The terms information security, computer security and information assurance are frequently used interchangeably. These fields are interrelated and share the common goals of…
The basic difference between go back ARQ and Selective Repeat ARQ Go-Back-N ARQ is a specific instance of the automatic repeat request protocol, in which the sending process continues to send the number of frames specified by a window size even without receiving an acknowledgement packet from the receiver. Selective Repeat ARQ/Selective Reject ARQ is…
Protocol, Syntax, Semantics and Timing in Networking? Protocol A protocol is a set of rules that govern data, communications. A protocol defines what is communicated how it is communicated, and the key elements of the protocol are Syntax, semantics, and timing. Syntax The term syntax refers to the structure or format of the data, meaning…
Advantages and Disadvantages of Bus Topology in Networking: Simply bus topology is known as linear topology. It consists of a computer that is attached to a common cable called a bus or trunk which is also known as the backbone of the network. Bus topology is one of the simplest network topologies. In this topology,…
Networking is an interconnection between two or more computer (nodes or hosts) etc… There are a lot of advantages and some disadvantage of networking. Advantages of Networking Sharing of Information: The ability to share data and information to users or computer connected to the computer network. i.e you can send email through the network. Sharing of…
