Networking devices


Common basic networking devices

ยท         Router: a specialized network device that determines the next network point to which it can forward a data packet towards the destination of the packet. Unlike a gateway, it cannot interface different protocols.
ยท         Bridge: a device that connects multiple network segments along the data link layer.
ยท         Switch: a device that allocates traffic from one network segment to certain lines (intended destination(s)) which connect the segment to another network segment. So unlike a hub a switch splits the network traffic and sends it to different destinations rather than to all systems on the network.
ยท         Hub: connects multiple Ethernet segments together making them act as a single segment. When using a hub, every attached all the objects, compared to switches, which provide a dedicated connection between individual nodes.
ยท          Repeater: device to amplify or regenerate digital signals received while sending them from one part of a network into another.
ยท         Modem: device that modulates an analog "carrier" signal (such as sound), to encoded digital information, and that also demodulates such a carrier signal to decode the transmitted information, as a computer communicating with another computer over the telephone network
ยท         RJ45 Connector: may refer to a registered jack connector and wiring pattern used for connection of a high-speed modem to a telephone network using a keyed 8P8C(8 position 8 contact) modular connector

Data communication Terminology

Data Communication Terminologies There are several common terminologies used in data communication literature: Channel: The word channel refers to the portion of a link that carries a transmission between a given pair of lines. One link can have many (n) channels. Data Rate: The data rate defines the number data elements (bits) sent in 1 second. The unit is bits per second (bps). Signal Rate: The signal rate is the numbers of signal elements sent in 1 second. The unit is baud . The data rate is sometimes called the bit rate : the signal rate is sometimes called the pulse rate, the modulation rate, or the baud rate. One goal in data communications is to increase the data rate while decreasing the signal rate. Increasing the data rate increases the speed of transmission; deceasing the signal rate decreasing the bandwidth requirement. Bandwidth: Bandwidth can be used in two different contexts with two different measuring values:- Bandwidth in Hertz: Bandwidth in ...

Program for Checking whether the given number is Palindrome or not

Palindrome means a number which remains same if positions of its digits is reversed i.e., 1221 #include<stdio.h> #include<conio.h> void main() { int n,digit,rev=0,num; printf("enter the number"); scanf("%d",&num); n=num; do { digit=num%10; rev=rev*10+digit; num/=10; }while(num!=0); printf("reverse number is=%d\n",rev); if(n==rev) { printf("number is palindrome"); } else { printf("number is not palindrome") ; } getch(); }
