LECTURE NOTES ON COMPUTER NETWORKS 2018 – 2019 III B. And sometimes computers send a lot of information like a whole movie or a piece of software to install that might take minutes or even hours to download. There are no servers in peer networks. other computer is available. Network Layer (Cont.) Basic of Networking A computer network consists of a collection of computers, printers and other equipment that is connected together so that they can communicate with each other. • IP is a standard that defines the manner in which the network layers of two hosts interact. BUS: A bus topology is multipoint. 3 Network IP Address Logical Address= 192.168.6.17 Usually, LAN covers an organization offices, schools, colleges or universities. So messages between computers can be short, medium, or long. Peer to peer network is useful for a small network containing less than 10 computers on a single LAN . Number of systems connected in LAN may vary from as least as two to as much as 16 million. Sign In. 2. In peer to peer network each computer can function as both client and server. A drop line is a connection running between the device and the main cable. Computers sometimes send medium-sized information like a single picture or a long email message. A tap is a connector that either The reach of a PAN is typically a few meters. •The devices may or may not belong to the person in question. Figure 1 : Computer Network Advantages of Computer Networks File sharing The major advantage of a computer network is that is allows file sharing and remote file access. 1.1. computer networking, introduces many terms, and provides a solid foundation before you get into more detailed subjects in later chapters. Kurose_Computer Networking A Top-Down Approach 7th edition.pdf. A person sitting at one workstation that is connected to a network can easily see files present on Nodes are connected to the bus cable by drop lines and taps. Personal Area Network (PAN) •A personal area network (PAN) is a computer network used for communication among computer devices, including telephones and personal digital assistants, in proximity to an individual's body. With a layered organization, students can see through the complexity of computer networking—they learn about the distinct concepts and protocols in one part of the architecture while seeing the big picture of how all parts fit together. Data Communication and Computer Networks Page 10 3. COMPUTER COMMUNICATION NETWORKS Department of ECE, ACE Page 1 COMPUTER COMMUNICATION NETWORKS UNIT 1 : INTRODUCTION TO NETWORKS Networking engineering is a complicated task, which involves software, firmware, chip level engineering, hardware, and electric pulses. Kurose_Computer Networking A Top-Down Approach 7th edition.pdf. K Munivara PrasadMr, Associate Professor CHADALAWADA RAMANAMMA ENGINEERING COLLEGE (AUTONOMOUS) Chadalawada Nagar, Renigunta Road, Tirupati – 517 506 Department of Computer Science and Engineering. network resources from peer to peer relationships. To ease network engineering, the whole networking Fig 1 gives an example of a network in a school comprising of a local area network or LAN connecting computers with each other, the internet, and various servers. A computer network spanned inside a building and operated under single administrative system is generally termed as Local Area Network (LAN). One long cable acts as a backbone to link all the devices in a network. The best-known computer network is the Internet. Connecting to Networks and the Internet The Networking Academy course that you are (likely) taking when using this book may be your first formal introduction to the world of computer networking. computer networking texts are often organized around the “layers” of a network architecture.
