2nd Meeting at Network Princeples and Programing Languages

•  Take quiz

Networks Principles and Programming Languages

Types Of TOPOLOGY :

There are six types of topologies:

•  Mesh topology.

•  Star topology.

•  Ring topology.

•  Tree topology.

•  Bus topology.

•  Hybrid topology

Mesh Topology:

In a mesh topology, every device has a dedicated point-to-point link to every other device. The term dedicated means that the link carries traffic only between the two devices it connects. Here, if we have n nodes, then we need to connect to n-1 nodes and n(n-1) physical links. However, if each physical link allows communication in both directions (duplex mode), we need n(n-1)/2 links.

Star Topology:

In local area networks where the star topology is used, each machine is connected to a central hub. The star topology allows each machine on the network to have a point to point connection to the central hub. All of the traffic which transverses the network passes through the central hub. The hub acts as a signal booster or repeater which in turn allows the signal to travel greater distances.

Ring Topology:

In local area networks where the ring topology is used, each computer is connected to the network in a closed loop or ring. The signal passes through each machine or computer connected to the ring in one direction, from device to device, until it reaches its destination. Each machines or computers connected to the ring act as signal boosters or repeaters. When a device receives a signal intended for another device, its repeater regenerates the bits and passes them along.

Tree Topology:

The type of network topology in which a central 'root' node (the top level of the hierarchy) is connected to one or more other nodes that are one level lower in the hierarchy (i.e., the second level) with a point-to-point link between each of the second level nodes and the top level central 'root' node, while each of the second level nodes that are connected to the top level central 'root' node will also have one or more other nodes that are one level lower in the hierarchy (i.e., the third level) connected to it, also with a point-to-point link, the top level central 'root' node being the only node that has no other node above it in the hierarchy

Bus Topology:

In local area networks where bus technology is used, each machine is connected to a long, single cable. The cable acts as a backbone to link all the devices in a network. Each computer or server is connected to the single bus cable through drop lines and some kind of connector. A terminator is required at each end of the bus cable to prevent the signal from bouncing back and forth on the bus cable.

Hybrid Topology:

Hybrid networks use a combination of any two or more topologies in such a way that the resulting network does not exhibit one of the standard topologies (e.g., bus, star, ring, etc.). A hybrid topology is always produced when two different basic network topologies are connected.

5th meeting @ Software Engineering

Good Evening All; Lesson learned for this meetings are:

 *  THE WATERFALL MODEL

THE PHASES OF WATERFALL MODEL

• Requirement analysis and definition
• System and Software design
• Implementation and unit testing
• Integration and system testing
• Operation and maintenance

*  The Waterfall Model Problem

    - Flexible Partitioning

    - Few System have stable requirements

    -

2nd Meeting @ Software Engineering

INTRODUCTION;

Engineening
            =   Engineering the applcation of science in the design, Planning, contruction and maintenance of building , Machines, and other manufacturing.

  Software
             = Program and application that can be run on a comuter system. Ex. Word Processing or Database package.

THINGS WE LEARNED:

• The two factors of Sofware Engineering
• Kinds of software products
• Software Engineering Diversity
• Ethics of Software Engineering

First Meeting @ Software Enginnering

In this session we are doing 3 things as mention bellow.

       Making our Blogs , Gmail and Drop Box account.

 I Would like to thanks my instructor for this another learnings and also my classmates. :)
