Fundamental of Computing

 Network Devices It is a physical devices that allow hardware on a computer network to communicate and interact with one another. It can transmit and receive wireless hart data and perform the basic functions. Repeater   A repeater is  a powerful network hardware device that regenerates an incoming signal from the sender before retransmitting it to the receiver  It is also known as a signal booster, and it helps in extending the coverage area of networks. The Incoming data can be in optical, wireless or electrical signal. Hub It is the a multiport repeater which connects multiple wires which come from differnet braches.  An example is a USB hub, which allows multiple USB devices to connect to one computer, even though that computer may only have a few USB connections. Types of Hubs Active Hub Passive Hub Intelligent Hub Switches Switches  are key building blocks for any network and connect multiple devices.  A network switch could be used to connect a computer, printer and server and p

                     Computer network and hardware essentials        Network Communication Kilobit is used to measure the amount of data transferred per second. Kilobits per second is shortened to kb/s, Kbps or kbps (as opposed to   Kbps  which is Kilobytes per second) .  the lowercase b is commonly used to denote bits, and the other Uppercase B is used foe bytes K stands for 1024 ....210(2 power 10) k stands for 1000.....103(10 power 3) 1 kbps = 1000 bits per second 1 KBps = 1024 bytes per second   So an internet speeds of 512kb/s can never achieve  download speed of 512KB/s formula to calculate the maximum download is [ download KB/s speed =( kb/s value*1000/8)/1024.      Components of network  Hardware Component NIC= Network Interface card- is hardware components that  physically connects computer and network    network medium  is a cable that plugs into the NIC and makes the connection between the computer and the rest of the network. interconnecting device  all
