Process: Processes are basically the programs that are dispatched from the ready state and are scheduled in the CPU for execution. PCB(Process Control Block) holds the concept of process. A process can create other processes which are known as Child Processes. The process takes more time to terminate and it is isolated means it does not share the memory with any other process....
The address through which any computer communicates with our computer is simply called an Internet Protocol Address or IP address. For example, If we want to load a web page or we want to download something, we require the address for delivery of that particular file or webpage. That address is called an IP Address....
In data communication terminology, a transmission medium is a physical path between the transmitter and the receiver i.e. it is the channel through which data is sent from one place to another. Transmission Media is broadly classified into the following types:...
An operating system acts as an intermediary between the user of a computer and computer hardware. The purpose of an operating system is to provide an environment in which a user can execute programs conveniently and efficiently....
This could also be seen as a way of how TCP connection is established. Before getting into the details, let us look at some basics. TCP stands for Transmission Control Protocol which indicates that it does something to control the transmission of the data in a reliable way....
Full Adder is the adder that adds three inputs and produces two outputs. The first two inputs are A and B and the third input is an input carry as C-IN. The output carry is designated as C-OUT and the normal output is designated as S which is SUM. The C-OUT is also known as the majority 1’s detector, whose output goes high when more than one input is high. A full adder logic is designed in such a manner that can take eight inputs together to create a byte-wide adder and cascade the carry bit from one adder to another. we use a full adder because when a carry-in bit is available, another 1-bit adder must be used since a 1-bit half-adder does not take a carry-in bit. A 1-bit full adder adds three operands and generates 2-bit results....
Simple Mail Transfer Protocol (SMTP) is an ASCII protocol. It is based on client-server model. It uses TCP port number 25 for this service. Therefore e-mail; is delivered from source to destination by having the source machine established a TCP to port 25 of the destination machine. To send mail, a system must contain client MTA and to receive a mail, a system must have server MTA. SMTP transfers this message from client MTA to the server MTA. To send a mail, SMTP is used two times: one between sender and sender’s mail server and the other between the two mail servers....
Both Stop and Wait protocol and Sliding Window protocol are the techniques to the solution of flow control handling. The main difference between Stop-and-wait protocol and Sliding window protocol is that in Stop-and-Wait Protocol, the sender sends one frame and wait for acknowledgement from the receiver whereas in sliding window protocol, the sender sends more than one frame to the receiver and re-transmits the frame(s) which is/are damaged or suspected....
Star Topology: In Star topology, the nodes are connected to the central hub or router in which the information is travel from the central hub or router to all the nodes. There are n links in Star topology if there are n nodes. The nodes are connected to each other completely via a dedicated link in which the information is travel from node to node....
Prerequisite – Open shortest path first (OSPF)
Open shortest path first (OSPF) is a link-state routing protocol which is used to find the best path between the source and the destination router using its own SPF algorithm....
In this article, we will discuss the overview of an entity and identifying and non-identifying relationships and finally will focus on differences between both of them. Let’s discuss it one by one....
CPU scheduling algorithms require CPU time and IO time required for its execution. CPU time is time taken by CPU to carry out the process while I/O time illustrates the time required for I/O operation by the process....
