Grasps knowledge about technologies via Computer Network Assignment Help

As per current scenario, the computer is one of the basic subjects and required in every field such as commercial purpose or for personal need. Addition, subtraction, division, and multiplication are the quite simple calculation which can be done by calculator but there are many raw data and information which are stored in computers for operating activities. It is better to take Computer network assignment help to engross the knowledge about the system and its connections.

Systems are connected each other through networks that can be external and internal. Internet and intranet are the best examples of networking. It is the main source of connection through which we can be connected with other person sitting at its remote place. In the traditional era, we used to send letters and message and then wait for a long time to get the reply.

Technologies had changed the world.  To explore the latest technology and its essential points take Computer network assignment help.  Through the internet, the person can communicate with another person faster than any other resource.   Innovative techniques and optimal information upgrades source of learning. Complex networking structure and computer networks both make our life easy and comfortable.

Let’s understands via Computer network assignment help what is a computer network?

-          It allows the exchange of data and packet between two distant sources.

-          It needs data connection to transfer information from one system to other

-          Connection Media can be cable or wireless device

-           Best and commonest example is the internet

-          Gets instant acknowledgment in one-one communication

Types of computer connections

A termed Topology is used for the different arrangement of the system in a network. There are   4 types of topologies:

-          Star Topology: each host system is connected to the central hub. This is the best example of point-to-point connection as each host system is directly connected to the central system. So all the host system work independently.

-          Ring Topology: It forms rings like structure, one host system is connected to another host system end to end. It has a disadvantage if one system fails then all stop working. The signals flow from one point to other.

•     Bus Topology: Every host system is connected with the single cable so every point gets the signals at a time.
  
•        Hybrid Topology: It is the combination of two or more topologies.
  

Types of Computer Network

It is basically divided into three main categories:

1. Local Area Network (LAN):  As the name suggests it is used for the short distance such as schools, colleges, and small organization.
   
2. Metropolitan Area Network (MAN): it is used to connect two blocks in a city and cover more than LAN.
   
3. Wide Area Network (WAN): it is used for distant geographical locations.
   
4. WLAN (Wireless Local Area Networks):  basically, it connects in the small distance but doesn’t require cables and wires for connection.
   

These are some of the common Networks required to establish a connection:

• Hubs are used for  connection of system  which are in simple topologies
  
• Repeaters are the device which accepts the signals and retransmit with high power.
  
• Modem, basically used for modulation and demodulation which transmit data through the telephone line in the form of analogs signals and receive back as digital signals.
  
• NIC (Network Interface Card) is hardware component used to connect the computers to home network or internet.
