Case's transimission

The unicast transmission is used to refer to one device which will send a message to another device in one to one communications. A unicast packet has a destination IP address that is a unicast address which will then go out to a single recipient froman source IP address that can only be a unicast address because the packet can only originate from a single source.This is regardless of the weather of an destination of an IP address which is a unicast,broadcast or multicast. A multicast is a transmission which is reduced by traffic that allows an host to send a single packet to a selected set of hosts that subscribe to a multicast group. A multicast packet is a packet that has a destination for a certain IP address which is a multicast address. IPv4 has reserved the 224.0.0 to 239.255.255.255 address and has a multicast range. Hosts can receive particular multicast packages called multicast clients and they use services which are requested by a client program to help subscribe to the multicast group. Each multiple cast group is represented by a single IPv4 multicast destination address however when an IPv4 host subscribes to a multiple cast group then the host processes packages which are addressed to the multicast address and packages are addressed to its uniquely allocated unicast address. The routing protocol such as OSPF that is used to multicast transmission for example the router enabled with the OSPF which communicates with each other while using the reserved OSPF that is a multicast address of 224.0.0..5. The only devices with these OSPF will helps to process these packages with 224.0.0.5 as the destination of an IPv4 address and all of device will ignore these packages. Legacy Classful Addressing In the year of 1981,IPv4 addresses were assigned to using classful addressing as defined in the RFC 790 (https://tool.ietf.org/html/rfc790) is assigned to numbers. The custors were allocated a network address based on one of the three classes A,B or C. The RFC is divided into the unicast range into specific as follows: Class A (0.0.0/8 to 127.0.0.08) that is designed to help support extremely large networks with more than sixteen million host addresses. Class A is used to help fix 8 prefixes with the first octet to indicate the network address and the remaining three octets for the host address more than sixteen host addresses per network. Class B (128.0.0.0/16 -191.255.0.0/16) is designed to support the need of moderate to large size networks with up to approximately 65,000 host addresses. Class B is used to fix up to 16 prefixes with the two high order octets to indicate the network address and the remaining two octets for host address. More than 65,000 host addresses per network. Class C (192.0.0.0/24 - 223.255.255.0/24) is designed to help support small networks with a maximum of 254 hosts. Class C is used to fix up to 24 prefixes with the first three octet to indicate the network and the remaining octet for the host addresses only has 254 host addresses per network. Carrier can sense multiple access/collision avoidance (CSMA/CA) is a type of protocol for the carrier to transmit IN. 802.11 networks. It was developed to help minimize the potential of a collision occurring when two or more stations send their signals over a data link layer. IDF stands for Intermediate Distribution Frame which is used for a free standing or wall-mounted rack for managing and interconnecting a telecommunications cable between end user devices and the main distribution frame. MDF stands for Main Distribution Frame which is used for the purpose of an MDF or main distribution facility is to connect and manage the wiring used for telecommunication between a service provider and IDFs. A Reaper is a complete digital audio production application for computers that offers a full multitrack audio and MIDI recording to the existing processing mixing and mastering toolset. The reaper is used to help support a vast range of hardware digital formats and plugins and can be comprehensively extended to be scripted and modified.

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
