Spiral model was originally proposed by Boehm.It is an evolutionary software process model which is a combination of an iterative nature of prototyping and controlled and systematic aspects oftraditional waterfall model.

The most fundamental calculation in the COCOMO model is the use of the Effort Equation to estimate the number of Person-Months required to develop a project. Most of the other COCOMO results, including the estimates for Requirements and Maintenance, are derived from this quantity. Basic COCOMO Basic COCOMO computes software development effort (and cost) as a …
A switch is used in a wired network to connect Ethernet cables from a number of devices together. The switch allows each device to talk to the others. Switches aren’t used in networks with only wireless connections, since network devices such as routers and adapters communicate directly with one another, with nothing in between. A …

If you want to add your computer to a network or a network device like a router then you need to install or configure your network card. Every new computer and motherboard you buy nowadays has a built in network port known as RJ45 socket. If you have an older computer or a motherboard that …
What is Digital Computer ? Digital computer is any of a class of devices capable of solving problems by processing information in discrete form. It operates on data, including magnitudes, letters, and symbols, that are expressed in binary form i.e., using only the two digits 0 and 1. By counting, comparing, and manipulating these digits …

Hubs, Bridges, Switches and Routers are used to build networks. If you are trying to design your own LAN (Local Area Network) at home, then you probably need to know what they do and the main differences between them. I will try to cover all that in addition to some networking details to cultivate the …
The means through which data is transformed from one place to another is called transmission or communication media. There are two categories of transmission media used in computer communications. (1) Bounded/Guided Media. (2) UnBounded/UnGuided Media Bounded/Guided Media Bounded media are the physical links through which signals are confined to narrow path. These are also called guide media. …
In Computer networks, a topology is a usually schematic description of the arrangement of a network, including its nodes and connecting lines. There are two ways of defining network geometry: the physical topology and the logical (or signal) topology.The physical topology of a network is the actual geometric layout of workstations. There are several common …
A local Area Network (LAN) is a computer network that interconnects computers in a limited area such as a home, school, computer laboratory, or office building using network media. The defining characteristics of LANs, in contrast to wide area networks (WANs), include their smaller geographic area, and non-inclusion of leased telecommunication lines. Ethernet: Ethernet is a 10Mbps …
