Interconnecting Devices An Interconnecting devices is a network device. It used to transfer data from one computer to other computer with the help of network devices. There are five categories of interconnecting devices are such as. Router  Hubs  Switches/Bridge  Repeater  BRouter Repeater: Now I am going to tell you the repeater is an electronic device that used to receive and send a signal. It amplifies the signal and noise. It provides transmission of the signal.  HUB (Hyper User Bus):  In this, it used to link several computers in the same network. It based on broadcasting, and it sends the data to all computers and repeats the signal which receives a signal from one port and copies to other port and traffic are high. Bridge / Switch:  In this, we can see the interconnecting devices which can divide a single network into two or more segment are called Bridge / Switch.  It has multiple ports like 2, 4, 16, and 32. The Switch maintains MAC-TABLE (MEDIA ACCESS CONTROL) and The Bridge

Rollover Crimping It is used for connecting Router Console Port to PC Com Port. The following color patterns are  Brown  Brown white  Blue  Blue white  Green  Green white  Orange  Orange white Rollover Crimping  

Crossover Crimping It is used between like devices (Similar Devices) such as Hub to Hub, PC to PC, Switch to Switch, Hub to Switch and PC to Router  DTE (Data Terminal Equipment)   - DTE (Data Terminal Equipment) DCE (Data Communicating Equipment) - DCE (Data Communicating Equipment) Connecting same device The following color patterns are  Orange White  Orange  Green White  Blue  Blue White  Green  Brown White  Brown A Cross Crimp is consists of colors such as orange-white, orange, green-white, blue, blue-white, green, brown-white, and brown this is the color patterns were used for cross crimp and the following diagram is given below. Crossover Crimping

Straight Crimping It used between unlike device (dissimilar devices) such as Hub to PC, Switch to Hub and Hub to Router. DTE (Data Terminal Equipment) - DCE (Data Communicating Equipment) Different device Example: PC and Router Communicate with Modem, Hub, and Switch The following color patterns are Green white  Green  Orange white  Blue  Blue white  Orange  Brown white  Brown  A straight crimp is consists of color such as green-white, green, orange-white, blue, blue-white, orange, brown-white, and brown these are the color patterns were using for straight crimp and the following diagram is given below Straight Crimping

Types of Crimping There are three types of crimp with Twisted Pair Cable  Straight  Crimping ( Different device ) DTE - DCE  Cross Crimping ( Connecting same device ) DTE - DTE  & DCE - DCE Rollover Crimping ( Connecting Router Console Ports to PC Com Ports)  Where,  DTE – Data Terminal Equipment   (Used in PC, Router)  DCE – Data Communicating Equipment   (Used in Modem, Hub, and Switch)

Crimping The Configuring of cables with respective connector is called Crimping. The commonly used cables for crimping are Cat 5, Cat 5e and Cat 6 and these cables connected with RJ45 connector. It used to connect network devices such as PC, Hub, Switch, Router, Modem, Router Console Ports and PC Com Ports. Twisted Pair cable is have 4 pairs of wire  Green  Green white  Blue  Blue white  Orange  Orange white  Brown  Brown white

Computer Peripherals A Computer Peripherals is a combination of Input and Output devices. Therefore the process of peripherals device is to put information into computer and get information from computer for users and other devices. Therefor the computer perform some operations by connecting a peripherals devices to the computer machine. For example like keyword connected to computer for giving input information to the computers. The computer peripheral is a hardware component. It used to provide a input and output operations to a computers machines. The following input and output devices pictures are given below. Input Devices When you work with the computer to enter your data and instructions through some devices to the computer. Therefore these devices are called input devices and the input devices are necessary to convert data or instructions enter into the computer to a form which can be recognized by the computer. Keyboard  Mouse  Scanner  Joystick  Microphone  Digital camera Out
