In our previous post Routing Concepts in Computer Networks we have explained the basic introduction of the routing concept. In the continuation of that post now in this article of Computer Science Study Material for Gate, we are going to tell about routing table. In this article provides the information about the different fields of a routing table with a suitable example, what is the use of these fields and how a particular route is selected for the destination host. So let's start with the introduction of routing table. http://www.computersciencejunction.in/2017/12/Study-Material-for-Gate-Computer-Science-routing-table-in-computer-network.html

What is Process Control Block ? Today in this Computer Science Study Material for Gate we will discuss about process control block and its various field which provides the information about process. .So let see what is process control block. A Process Control Block is a data structure maintained by the Operating System for every process. Each process has it own data structure. When a process is created then a unique id is assigned to the process Operating system identify a process among all processes on the basis of this process id. A PCB keeps all the information needed to keep track of a process. Generally a process control block contains the following information about a process.

TCP/IP protocol based questions for gate computer science exam Q1.What is the difference between transport and session layer of OSI model. Answer: OSI Model Transport Layer The transport layer uses the services provided by the network layer, such as best path selection and logical addressing, to provide end-to-end communication between source and destination. • The transport -layer data stream is a logical connection between the endpoints of a network. • End-to-end control is provided by sliding windows and reliability in sequencing numbers and acknowledgments. The transport layer regulates information flow to ensure end-to-end connectivity between host applications reliably and accurately. • The TCP/ IP protocol of Layer 4 (t transport t layer ) has two protocols. They are TCP and UDP. The transport layer accepts data from the session layer and segments the data for transport across the network. Generally, the transport layer is responsible for making sure that the data is delivered error-free and in the proper sequence. Flow control generally occurs at the transport layer. OSI Model Session Layer The session layer establishes, manages, and terminates communication sessions. Communication sessions consist of service requests and service responses that occur between applications located on different network devices. These requests and responses are coordinated by protocols implemented at the session layer. The session layer establishes, manages, and terminates sessions between applications Functions of the session layer and the different processes that occur as data packets travel through this layer. More specifically, you learned that Communication sessions consist of mini-conversations that occur between applications located on different network devices. Requests and responses are coordinated by protocols implemented at the session layer. • The session layer decides whether to use two-way simultaneous communication or two-way alternate communicati

In this post under Computer Science Study Material for Gate, we are going to tell the differences between File Transfer Protocol (FTP) and Hypertext Transfer Protocol (HTTP). File Transfer Protocol FTP and HTTP both were developed to make Internet transmission better. FTP is used to exchange files between computer accounts, to transfer files between an account and a desktop computer (upload), or to access software archives on the Internet. It 's also commonly used to download programs and other files to your computer from other servers. It transfers files in two different formats ASCII for text files and Binary format for binary files.
