Network Hardware & Software Components

Network Hardware & Software Components

1. Interconnections

   • It means to link the computers together in a network , you would need
   • Bandwidth
     • Is the term used to describe the amount of data transmitted across a network
   • Different interconnections are able to carry different bandwidhts

2. Hardware Components

   • Its a Physical components , its something that you can touch
   • Peripherals
     • External devices that are connected to the computer
     • Input Devices
       • Enables a turn things from the real human physical world into data for the digital e.g Keyboard , Mouse , Microphone
     • Output Devices
       • Take data from the digital world and communicate it with the real human physical world e.g. Monitor
     • Storage Devices
       • Backing storage is used to save data and retrieve it later e.g Hard Drive, DVD
   • Main Memory
     • RAM
       • RAM stands for Random Access Memory
       • Memory in which data is temporarily stored for processing. Its a volatile it means when the computer switch off you lost your work
     • ROM
       • ROM stands for Read Only Memory
       • ROM is a permanent, and its non volatile which means when the computer switch off you don't lose your work
   • Processor
     • ALU
       • ALU stands for Arithmetic Logic Unit
       • It main function is to performs arithmetic functions on the data and it does all the maths
       • It also performs logical operations on the data
     • Control Unit
       • It mains function is to manages how CPU instructions are carried out and coordinates memory and Peripherals
   • Registers
     • its a chip memory that monitor ,store binary data and control the information being Fetched and executed ( Fetch cycle )
   • Buses
     • Buses are circuits used to move binary data around the computer
