Types Of Computer Network
WAN ( Wide Area Network)
WAN covers the broad area which may span across provinces and even the whole country. It is a sector of telecommunication that the system is utilized. The network is esteemed high speed, so the users spend time to take the money from these services. Government entities, business organizations and other education facilities use to get connected and transmit data to each other. Different technologies are used to develop the wide area network links from integrated telephone lines, radio wave transmission and the optical fiber.
LAN (Local Area Network)
LAN is confined to a single room, building or group of buildings; however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves. A system of LANs connected in this way is called a wide-area network (WAN). It is storage when systems are shared among the users. Today, Ethernet and Wi-Fi are the most common forms of LAN usage. It is effectiveness, flexibility, and cost. The LAN comprises two or three switches which are connected to the router or modem for internet access. LAN consist of several switches which a protocol prevents loops and manages more volumes of data transmission.
The network mostly used in recent private, public, business, academic and government networks are connected and guided by wireless and fiber optic technology. It is a network of globally connected technologies that use TCP/IP to transmit data.
It is an ideal of networking model for the future and also connects the endpoints through the public web. It is a transmission of data and exchanging information to a physical location. It is the high capacity of networks and peer-to-peer architecture has paved the way for the popularity of internet networking.
MAN (Metropolitan Area Network)
A metropolitan area network (MAN) is similar to a local area network (LAN) but spans an entire city or campus. MANs are formed by connecting multiple LANs. Thus, MANs are larger than LANs but smaller than wide area networks (WAN). MANs are extremely efficient and provide fast communication via high-speed carriers, such as fiber optic cables. It is used to build networks with high data connection speeds for cities and towns. It facilitates equip the whole city such as cable tv networks and can be used in various forms like Ethernet, token ring, ATM or FDDI. This network links generally use the microwave, radio or infra-red laser transmission to connect between two LANs. It can extend up to 40 kilometers to maintaining its speed and effectiveness.
CAN (Campus Area Network)
A campus area network (CAN) is a network of multiple interconnected local area networks (LAN) in a limited geographical area. A CAN is smaller than a wide area network (WAN) or metropolitan area network (MAN). A CAN is also known as a corporate area network (CAN) where the employees require high-speed data links.
SAN (Storage Area Network)
A storage area network (SAN) is a secure high-speed data transfer network that provides access to consolidated block-level storage and cannot perform file abstraction. SAN makes a network of storage devices accessible to multiple servers. SAN is assembled using three principles are cabling, Host Bus Adapters, and switches. It recognizes a common network into high speed and independent work.
PAN (Personal Area Network)
A personal area network (PAN) refers to the interconnection of information technology devices or gadgets within the environment of an individual user. These interconnected devices might include laptop computers, PDAs, cellphones, printers, PCs or other wearable computing devices and also known as a wireless personal network (WPAN).
SAN (System Area Network)
A SAN is linked to high-performance computers with high-speed connections in a cluster configuration and it is also known as Cluster Area Network. It provides a high-speed switched environment in which any device on the network can connect with any other device and communicate over a dedicated high-speed link.
Advantages And Disadvantages Of Computer Networking
The computer network allows the user to connect across the globe as if they were in the same room. It is also a negative aspect like a security risk, workplace distraction, etc.
It is one of the major concepts of the network. If you are setting a network for the purpose of the business you need to spend thousands of dollars.
It supports government agencies to detect any kind of unwelcome behavior from any source.
Communication And Information
It allows communicating with your friends, relatives, etc. It is like an instant sharing your data that you will easily deliver your files to another person within a minute. Internet is access to vast information.
It can share both hardware and software resources through a well-designed network. It increases efficiency and facilitates workplace collaboration.
Common Network Devices
The fundamental units of networking that carry data through a computer network. These are as follows:
Hub connects the computers together in a star topology network. It has multiple ports that are commonly used to connect segments of a network. When a data packet is inserted to one of its ports, it is copied to other ports to give all segments to see all packets. It performs as the central connection of the networking and carries data in the form of frames.
A network device used to regenerate or replicate a signal. Repeaters are used in transmission systems to regenerate analog or digital signals distorted by transmission loss. Analog repeaters frequently can only amplify the signal while digital repeaters can reconstruct a signal to near its original quality.
A modem is a device or program that enables a computer to transmit data over, for example, telephone or cable lines. Computer information is stored digitally, whereas information transmitted over telephone lines is transmitted in the form of analog waves. A modem converts between these two forms.
NIC( Network Infrared Card)
A Network Interface Card (NIC) is a computer hardware component that allows a computer to connect to a network. NICs may be used for both wired and wireless connections. It is also known as a network interface controller (NIC), network interface controller card, expansion card, computer circuit board, network card, LAN card, network adapter or network adapter card (NAC).
A media converter, in the context of network hardware, is a cost-effective and flexible device intended to implement and optimize fiber links in every kind of network. Among media converters, the most often used type is a device that works as a transceiver, which converts the electrical signal utilized in copper unshielded twisted pair (UTP) network cabling to light waves used for fiber optic cabling. It is essential to have the fiber optic connectivity if the distance between two network devices is greater than the copper cabling’s transmission distance.
A network switch (also called switching hub, bridging hub, officially MAC bridge) is a computer networking device that connects devices on a computer network by using packet switching to receive, process, and forward data to the destination device. It is a multi-port network bridge that uses hardware addresses to process and forward data and it operates at the data link layer of the OSI model. Some switches can also process data at the network by additionally incorporating routing functionality. Such switches are commonly known as layer-3 switches or multilayer switches.
A router is a network layer of the OSI reference model device that means it can connect multiple computer networks via wired or wireless connections. Network router can receive, analyze, perform the traffic directing functions and forwards data packet from one network to its destination node. A router is a device that forwards packets between networks by processing the routing information included in the packet.
A firewall is a system designed to prevent unauthorized access to or from a private network. You can implement a firewall in either hardware or software form, or a combination of both. Firewalls prevent unauthorized internet users from accessing private networks connected to the internet, especially intranets. All messages entering or leaving the intranet (the local network to which you are connected) must pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria. network assignment help
Basic DHCP (Dynamic Host Configuration Protocol) Server
The Dynamic Host Configuration Protocol (DHCP) is integral to networks and controls what IP addresses devices receive so they can communicate with the internet. Usually, IP assignment is automated, but if you need static IPs, familiarity with DHCP is essential.
