The incremental development model is a prescriptive model which delivers the working component at each increment of the project. Incremental model is implemented when the client needs an immediate release of the project. In this section, we will discuss the characteristics of the incremental model in brief, along with its phases. We will also consider the scenario when the … [Read more...] about Incremental Development Model
Prototyping Model
Prototyping is a process model which is used to develop softwares. The main purpose of the prototyping model is to satisfy the customer’s need. To acquire this, developers implement the prototype and present it to the customer for evaluation. After evaluation customer suggests the modifications in the prototype. The suggested modifications are then implemented in the prototype … [Read more...] about Prototyping Model
Spiral Model
Spiral model is a software development model introduced by Barry Boehm to decrease the uncertainty at each stage of software development. This model incorporates features of both the waterfall model and prototyping model. It is a risk-driven process model and its most important feature is to decrease the risk of the project. In this section, we discuss features of the spiral … [Read more...] about Spiral Model
Waterfall Process Model
A waterfall process model is considered as a dominant software development model used by software engineers from last three decades. This model divides the entire process of software development into a number of independent stages. Further, these independent stages are carried out in a sequential manner to obtain the final product (software). In this section, we will be … [Read more...] about Waterfall Process Model
User Interface Design
User Interface Design is a process of designing or fabricating the interfaces through which the user can communicate with the computer. It the software engineer who accomplishes the task of designing the user interface. Software engineer makes it sure that the user interface is easy to understand, achieve goals, good to use, encouraging and forgiving. In this section, we … [Read more...] about User Interface Design
Distance Vector Routing Protocol
Distance Vector Routing protocol is a 'dynamic routing' protocol. With this protocol, every router in the network creates a routing table which helps them in determining the shortest path through the network. All the routers in the network are aware of every other router in the network and they keep on updating their routing table periodically. This protocol uses the principle … [Read more...] about Distance Vector Routing Protocol
Mobile IP
Mobile IP is a communication protocol which is introduced as an improved version of the IP protocol. With mobile IP the host can move to a different network and still be connected to its home network and can communicate with the remote hosts. In this section, we will discuss mobile IP, it working, several entities of mobile IP, advantages and disadvantages of mobile … [Read more...] about Mobile IP
Internet Control Message Protocol version 4 (ICMPv4)
ICMPv4 Internet Control Message Protocol version 4 is definitely a Network layer protocol and its job is to report the error to the source if any problem arises while delivering the datagram from the source host to the destination host. The ICMPv4 is a message-oriented protocol. It’s a protocol of version of 4 of TCP/IP protocol suite. In this section, we will discuss the … [Read more...] about Internet Control Message Protocol version 4 (ICMPv4)
Address Resolution Protocol (ARP)
Address Resolution Protocol (ARP) is a dynamic mapping protocol that maps the IP address of a computer to it's MAC address. ARP maps the 32-bit IPv4 address of the receiver to 48-bit MAC address of the receiver. The Address Resolution Protocol is a Network Layer protocol. There also exists a reverse ARP protocol (RARP) that translates MAC address to IP address. In this … [Read more...] about Address Resolution Protocol (ARP)
Difference Between Private and Public IP address
Both private and public IP address identifies a specific computer in a network but still, they differ in many ways. Private IP address is an IP address that identifies a specific computer in a private network. On the contrary, a public IP address identifies a specific computer over the global internet. Private address need not be unique universally but, it has to be unique in … [Read more...] about Difference Between Private and Public IP address
