Switching and It's Types

Circuit-Switched Networks Datagram Networks Virtual-Circuit Networks Structure of a Switch A switched network consists of a series of interlinked nodes, called switches. Switches are devices capable of creating temporary connections between two or more devices linked to the switch. In a switched network, some of these nodes are connected to the end systems, others are used only for routing. A circuit-switched network consists of a set of switches connected by physical links. A connection between two stations is a dedicated path made of one or more links. Each connection uses only one dedicated channel on each link. Each link is normally divided into n channels by using FDM or TDM.

Questions On Computer Organisation

These are few assignment questions on computer organisation and micro processors which covers some basic topics like architecture of 8085 and basics of computer organisation.

Sixth Sense Technology

Sixth Sense is a wearable gestural interface that augments the physical world around us with digital information and let us use natural hand gestures to interact with that information. Steve Mann is considered as the father of Sixth Sense Technology who made wearable computer in 1990. He implemented the Sixth Sense Technology as the neck worn projector with a camera system. Sixthsense comprises a pocket projector,a mirror and a camera.The hardware components are coupled in a pendent like mobile wearable device.

Brief on Interview skills

Your interview starts before you walk into an employer’s door.. 1. Education 2. Experience, both paid and unpaid 3. Accomplishments and achievements 4. Skills and competencies 5. Community service 6. Clubs and organizations 7. Extra-Curricular activities 8. Work ethics 9. Values Create a professional resume. Look for ways to put a positive spin on your career history. Create a powerful, competent and experienced image by using action words to describe yourself and your accomplishments.

Interview Skills Part 2

AIM: To gain the practice of being interviewed by the interviewers To learnt to give appropriate answers in an interview. To develop the communication skills and to give spontaneous answers ACTIVITY: Practiced 3 types of interviews. 1.PANEL INTERVIEW: A panel of 2 (or) 3 members will be the interviewers and they interview the interviewee. 2.FACE TO FACE: One interviewer interviews the interviewer. 3.TELEPHONIC INTERVIEW: The interview will be carried over the phone. The questions that are to be considered before facing the interview: Self introduction (write self introduction: Name, place, educational qualifications, skills, strengths, family back ground, short and long goals, hobbies) Why do you choose this profession? Interest Passion Lot of scope for professional growth and research What attracted you to our organization? Reputation of the organization Provides the chance for the professional growth Chance to get more promotions Working environment

allows people to communicate on a given topic in a cohesive manner. JAM includes an introduction, a few relevant /supportive points a conclusion. Smile Don’t be nervous Be simple and use clear language Be brief Speak in an audible and clear voice Use correct grammar. If you are given an option to choose a topic…choose a topic related to Social, Political, Economical, Legal/Language or Technical (SPELT). Maintain a positive outlook. Finish with a Thanking note.

Presentation on ZigBee Technology

No wireless network standard that meets the unique needs of sensors and control devices. wireless systems don’t require high data rates but do require low cost and very low current drain. proprietary systems are creating significant interoperability problems with each other and with newer technologies. Low power consumption High density of nodes per network Simple protocol, global implementation Network Flexibility License free operation in 2.4 GHz band Small size-less than 9 mm*9 mm Hundreds of devices per Network

PROJECTIONS OF PLANES

This chapter deals with 2D- dimensional objects called planes. Planes have length, breadth and negligible thickness. The surface of a plane may be in one of the following positions as shown in fig. Parallel to H.P (& perpendicular to V.P). Parallel to V.P (& perpendicular to H.P). Perpendicular to both H.P & V.P. Inclined to H.P & perpendicular to V.P. Inclined to V.P & perpendicular to H.P. Inclined to both H.P & V.P.

Engineering Cycloid Curves

ENGINEERING CURVES CYCLOID: A cycloid is a curve generated by a fixed point on the circumference of circle, when it rolls along a straight line without slipping. INVOLUTE: IT IS A LOCUS OF A FREE END OF A STRING WHEN IT IS WOUND ROUND A CIRCULAR POLE. Solution Steps: 1)      From center C draw a horizontal line equal to D distance. 2)      Divide D distance into 8 number of equal parts and name them C1, C2, C3__ etc. 3)      Divide the circle also into 8 number of equal parts and in clock wise direction, after P name 1, 2, 3 up to 8. 4)      From all these points on circle draw horizontal lines. (parallel to locus of C) 5)      With a fixed distance C-P in compass, C1 as center, mark a point on horizontal line from 1. Name it P. 6)      Repeat this procedure from C2, C3, C4 upto C8 as centers. Mark points P2, P3, P4, P5 up to P8 on the horizontal lines drawn from 2, 3, 4, 5, 6, 7 respectively. 7)      Join all these points by curve. It is Cycloid.

Introduction to Object-oriented analysis and design

Object-oriented analysis and design (OOAD) is a popular technical approach to analyzing, designing an application, system, by applying the object-oriented paradigm and visual modeling throughout the development life cycles to foster better stakeholder communication and product quality. UML stands for “Unified Modeling Language” It is a industry-standard graphical language . UML is a pictorial language used to make software blue prints It is used for specifying, visualizing, constructing, and documenting the artifacts of software systems UML is different from the other common programming languages It uses mostly graphical notations. Simplifies the complex process of software design
