Layer 1: Port Serial0/1/0 1. Serial0/1/0 receives the frame. Layer 2: HDLC Frame HDLC 1. The device de-encapsulates the payload from the HDLC frame and sends it to the upper layer. Layer 3: IP Header Src. IP: 192.168.1.2. Dest. IP: 192.168.0.2 ICMP Message Type: 0 1. The device looks up the destination IP address in the CEF table. Layer 3: IP Header Src. IP: 192.168.1.2, Dest. IP: 192.168.0.2 ICMP Message Type: 0 1. The CEF table has an entry for the destination IP address. 2. The device decrements the TTL on the packet. Layer 2: Ethernet II Header 0002.1732.6901 >> 000A.F3A8.111A 1. The next-hop IP address is in the adjacency table. The device sets the frame's destination MAC address to the one found in the table. 2. The device encapsulates the PDU into an Ethernet frame. Layer 1: Port(s): FastEthernet/0 1. FastEthernet0/0 sends out the frame.

Operators in C language

Operators One of the most important features of C is that it has a very rich set of built in operators including arithmetic, relational, logical, and bitwise operators. An operator can be any symbol like + - * / that specifies what operation need to be performed on the data. For ex: + indicates addition operation * indicates multiplication operation Operand VS Operator • An operand can be a constant or a variable. • An expression is a combination of operands and operators that reduces to a single value. For example: Consider the following expression: a+ b Here 'a' and 'b' are operand while 't' is an operator Operators & Expression are 1) Arithmetic Operators and Expressions 2) Assignment and Compound Assignment Operators 3) Increment and Decrement Operators 4) Relational Operators and Expressions 5) Logical Operators and Expressions 6) Bitwise Operators and Expressions Arithmetic Operators An arithmetic operator performs mathematical operators such

3D printers

3D  printers  A 3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process of an object that is being created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced cross-section of the object. 3D printing is the opposite of subtractive manufacturing which is cutting out / hollowing out a piece of metal or plastic with for instance a milling machine. 3D printing enables you to produce complex shapes using less material than traditional manufacturing methods. Slicing: From printable file to 3D Printer Slicing basically means slicing up a 3D model into hundreds or thousands of layers and that is done with slicing software. When your file is sliced, it’s ready for your 3D printer. Feeding the file to your printer can be done via USB, SD or Wi-Fi. Your sliced file is now
