Computer network and communication
As we all are living in a world of Worldwide Web, we should understand the role of computer networking in our life. Computer networks facilitate the remote access programs and remote databases for the user. Data can reside either on the intranet of the same organization or from other enterprises or public sources. As our Computer Network and Communication homework help Online tutors state you can sit in one place and communicate with someone else sitting in the remote place using the fundamentals of computer networking. It is the area that is influenced by the area of communication as well.
A computer network or data network is a telecommunications network that allows computers to exchange data. According to our Networking helpers in computer networks, networked computing devices (network nodes) pass data to each other along data connections. The connections (network links) between nodes are established using either cable media or wireless media. The best-known computer network is the Internet. It is a technical definition of computer networking; however, in native terms, it can be understood as a complex structure that connects different people sitting in remote geographical locations. Communication is facilitated using data packets that are routed through the network.
Types of computer connections
The mode of connection of the computers in a network is called Topology. Our networking tutors analyze the different type of topologies as following:
- Star Topology: In this type of computer topology there is a central node that extends a connection to each computer on the network. All the computers are independently connected to the central node, and if any communication breaks in between, they still operate without any problem.
- Ring Topology: In this type of topology all the computers are connected to each other end to end in the form of a ring. The signal circulates through the network until it finds the required terminal. In case there is any discontinuity in communication all the computers will stop operating.
- Bus Topology: In this type of topology all the computers and network devices are connected to a single cable or backbone so that all the nodes receive the message at the same time.
Types of Computer Network
Our Computer Network and Communication homework help professionals define the type of computer networks as three broad categories:
- Local Area Network (LAN): This type of network is used to serve small number people located in a limited geographical area. It is most often used inside organization’s offices, schools, colleges/universities, etc.
- Metropolitan Area Network (MAN): This type of network interconnects the computer devices in an area larger than that of LAN. It covers an area of a few city blocks to the area of an entire city.
- Wide Area Network (WAN): This type of network is used to serve large number people located in a much larger geographical area. It consists of other LANs and MANs.
- WLAN (Wireless Local Area Networks): Computer Network and Communication Assignment help experts define it as a network formed without the use of wires or physical media to connect different computers to the server.
So based on the concepts mentioned above our Computer Network homework help service providers give complete details of the following other types of networks like CAN (Campus Area Network), SAN (Storage Area Network), PAN (Personal Area Network) and SAN (System Area Network).
Common network devices
Network devices perform the task that carries data through a computer network. Our computer networking experts analyze the basic network devices that are used by users:
- Hub: It connects computers together in a simple topology network.
- Repeater: It is an electronic device that receives a signal and retransmits it at a higher level or higher power.
- Modem: modem is a device that performs the function of modulation and demodulation.
- NIC (Network Interface Card): It is a computer hardware component designed to allow computers to connect to the internet or network.
- Media converters: According to our Computer Network and Communication assignment helpers, these are simple networking devices that make it possible to connect two dissimilar media types such as a twisted pair with fiber optic cables.
- Bridge: This is a network device which connects multiple networks so that they communicate. Our computer network homework help service providers go on to explain that it operates at the data link layer of the OSI model. It can interlink two of their ports together at very high speed.
- Firewall: It is a part of a computer system or network that is designed to block unauthorized access while permitting outward communication.
There are many other network devices too like Switch, Router, and Basic DHCP (Dynamic Host Configuration Protocol) server
Important concepts of Computer Networking
Allassignmenthelp experts are highly qualified and well versed in the Networking concepts, and we always look forward to helping you in difficult topics given below:
- Introduction to networks and layered architecture: Fundamental of computer networking starts with the seven-layer architecture. It is known as OSI model where each layer has a specific function to perform. Learn more about computer networking papers and assignment by consulting our experts.
- Routing algorithms: Several routing algorithms provide an efficient and secure way of transmitting information. However, these algorithms are hard to understand and difficult to program. Our team of experts provides best programming assignment help based on Routing algorithms.
- Congestion control techniques: Just like the congestion on roads, networks also suffer from the same problem. If there are too many data packets crossing a network, it might lead to the congestion problem. Hence, networking experts have devised a solution to such problems by implementing network congestion control techniques using Java Programming or other programming frameworks.
- Network management and security: Network data theft and hacking are major issues in the networking world. Hence, you have to understand the importance of network management and the security mechanisms. It includes packet tracer assignments, Packet filters, and Nessus. You can take assistance with any of these topics
Apart from the topics mentioned above, our experts are comfortable with the topics, such as Circuit switching and packet switching, Transmission media and topology , IPV4 and IPV6,Data communication concepts, data link layer, layer two switches and ATM switches, SONET/SDH, Wireless communications, Medium access control, Internetworking, and WAN, etc.Buy networks course solutionsby experts and stay stress-free.
