Components of Computer Network

Components of Computer Network 



The  components that make up a computer network are - 

1. Client 
2. Server 
3. Middleware 
4. Router and Switch 
5. IP address 

Client - Client is a computer that retrieves information from or uses resources provided by the server or main computer.

Server - A server is an instance of a computer program that accepts and responds to requests made by client. 
Servers are used to manage network resources. 
For example, a user may setup a server to control access to a network, send/receive e-mail, manage print jobs, or host a website. 

Application Servers 
  • Audio/Video Servers
  • Chat Servers 
  • Fax Servers 
  • FTP Servers 
  • Groupware Servers 
  • IRC Servers 
  • List Servers 
  • Mail Servers
  • Proxy Servers 
  • Telnet Servers 
  • Web Servers
Middleware is the software that connects two otherwise separate applications.

Most networks today, including all computers on the Internet, use the TCP/IP protocol as the standard for how to communicate on the network. 

In the TCP/IP protocol, the unique identifier for a computer is called its IP address. TCP - is responsible for verifying the correct delivery of data from client to server. IP - is responsible for moving packet of data from node to node.

General electronics/digital aircraft systems are -  ECAM (Electronic Centralized Aircraft Monitoring) EFIS (Electronic Flight Instrument System) EICAS (Engine Indicating & Crew Alerting System) FMS (Flight Management System)      ECAM (Electronic Centralized Aircraft Monitoring) An  electronic  centralized  aircraft monitor  (ECAM) is a system, developed by Airbus , that monitors aircraft functions and relays them to the pilots.  ECAM produces messages detailing failures and in certain cases, lists procedures to undertake to correct the problem. Airbus developed ECAM, such that it not only provided the features of (Engine Indicating and Crew Alerting System)EICAS, but also displayed corrective action to be taken by the pilot, as well as system limitations after the failures. Using a color-coded scheme the pilots can instantly assess the situation and decide on the actions to be taken. ECAM was  designed to...
