By completing this section, you achieve the following objectives: • Define its computer networks. About $600 billion in intellectual property losses occur annually because of how we structure computer networks and use them. 2. Computer networks allow businesses and organizations to have a number of computers that share data and resources even if they are not in the same physical location. Some devices can act as hosts and peripherals. Main benefits of networks include: File sharing - you can easily share data between different users, or access it remotely if you keep it on other connected devices. Online collaboration tools include email, forums and chat, voice and video, and instant messaging. Advantages of computer networks . • Telephone system • Internet. In this Computer Network Advantages and Disadvantages post, we are going to study in detail about the advantages and disadvantages of a computer network, but for now, let’s focus on the differences. • Storage space on removable devices, such as hard drives or optical drives. Here’s a quick list of the most common uses for a network. According to the procedure of connection of the computers and range of area, there are many types of network available which are Peer-to-Peer Network, Server-based network, PAN (Personal Area Network… Converged data networks can include general-purpose computers, such as personal computers and servers, as well as devices with more specific functions, such as printers, phones, televisions, and game consoles. What is Bus Topology? An administrator can control the data, devices, and permissions of network users. Message Services: This service facilitates email, voice mails and coordinate object oriented applications. e. Networking provides a flexible networking environment. Peripherals are devices that are connected to hosts. 5. Application Services: This services allows to centralize high profile applications to increase performance and scalability. 3. Advantages and Disadvantages of Bus Network. The servers store the data and share it with the users of a network. If you’ve never used a network to link multiple computers, you might not realize which applications are network ready. Network devices connect through various connections: • Copper wiring: uses electrical signals to transmit data between devices. This classification also called computer architecture. What is the difference between computer networks and network communications. A host is any device that sends and receives information on the network. Duplication and file corruption are avoided, It is possible to distribute data processing among many computers to prevent a computer from being overloaded with processing tasks. • Laptops. Advantages of Network: These are main advantages of Computer Networks: Central Storage of Data – Files can be stored on a central node (the file server) that can be shared and made available to each and every user in an organization. Centralized administration reduces the number of people needed to manage devices and data on the network, allowing the company to save time and money. The major networking services are. The information on the network moves from one place to another, sometimes by different routes, to reach the correct destination. 2. • Print and file servers. Websites that allow people to create links to each other with their pages are called social networking sites. The print server can distribute print jobs among the various printers, or it can queue jobs that require a particular printer. The site license allows a group of people or an entire organization to usethe application for a single fee. Users of these computers can share programs, information, software, and even hardware like printers and scanners because the computers are linked through the network. Learn: What are Network topologies?In this article we will see the various types of Network topologies with their advantages and disadvantages. 1. Cars, trucks, and other vehicles are like the messages that travel on the net. Creating backup copies of the data is more comfortable because of the data stored in a central location. The Network is the interconnection between computers, laptops, servers, smartphones and other network devices for communication, data sharing, data transporting, data exchanging, operations. A network can be as simple as two computers connected by a single cable or as complex as hundreds of computers connected to devices that control the flow of, All converged networks of data, voice, and video share, A data network consists of a set of hosts connected by network devices. Acquiring application licenses can be expensive for individual computers. Network services are the thing that a network can do. Assuming that proactive systems are developed and installed to counter the effects of the potential disadvantages, a computer network, at any level of connectivity, will help every society come closer to its full potential. A set of related ideas can be called a conceptual network. We’ll be covering the following topics in this tutorial: Networks constitute systems formed by links. Advantages of computer networking. The purpose of the connection is mainly transfer or share data, share of resources such as printers, applications etc. The connections you have with all your friendscan be called your personal network. • Fiber optic cabling: uses plastic or glass cable, also called fiber, to transport information as the light emitted. A host is any device that sends and receives information on the network. Network topology refers to the arrangement of computers connected in a network through some physical medium such as cable, optical fiber etc. Many software providers offer site licenses for networks,which can significantly reduce the cost of the software. All converged networks of data, voice, and video share information and use various methods to direct the flow of information. If the printer is connected directly to a network device,such as a hub, a switch or a router, it acts as a host. Computer network can be classified on the basis of following features : By Scale: Computer networks may be classified according to the scale : What is a Computer Network? Resources such as printers, scanners and internet can be shared. • Wireless connection: uses radio signals, infrared (laser) technology, or satellite transmissions. The advantages and disadvantages of computer networking show us that free-flowing information helps a society to grow. In this system, there are rules, such as stop signs and traffic lights, that control the movement from origin to destination. Database Services: This involves coordination of distributed data and replication. The public transport system is similar to a data network. Computer network can be classified on the basis of following features : By Scale: Computer networks may be classified according to the scale : • Local Area Network (LAN) • Metropolitan Area Network (MAN) • Wide Area Network (WAN), By Connection Method: Computer networks can also be classified according to the hardware technology that is used to connect the individual devices in the network such as Optical fibre, Ethernet, Wireless LAN.
