Guidance for Interview

Wouldn't it be great if you knew exactly what questions a hiring manager would be asking you in your next job interview? While we unfortunately can't read minds, we'll give you the next best thing: a list of the 31 most commonly asked interview questions and answers. While we don't recommend having a canned response for every interview question (in fact, please don't), we do recommend spending some time getting comfortable with what you might be asked, what hiring managers are really looking for in your responses, and what it takes to show that you're the right man or woman for the job. Consider this list your interview question study guide.

Oral Communication Skills

Sentences are broadly divided into four kinds Assertive ( . ) Interrogative ( ? ) Exclamatory ( ! ) Imperative ( . ) Assertive sentence is also called as a declarative sentence, These sentences are used to state information. They are the most commonly used sentence type. Most academic writing employs simple or declarative sentences. Declarative sentences end with a period. For example: Research on the topic suggests that grammar is essential to success.

Presentation on Cloud Computing

…moving computing and data away from the desktop & the portable PC and simply displaying the result of computing that takes place in a centralized location and is then transmitted via internet to user’s screen. It offers the ability to access software or information that can be delivered on- demand , over the internet , without the need to store it locally. A simple example of Cloud Computing is Yahoo or Gmail etc. You don’t need a software or a server to use them. All a consumer would need is just an internet connection and you can start sending emails. The server and email management software is all on the cloud(internet) and is managed by the cloud service provider like Yahoo, Google etc. The consumer gets to use the software alone and enjoy the benefits. The analogy is “If you only need milk, would you buy a cow?”. All the users need is to get the benefits of using the software of computer like sending emails etc.. Just to get this benefit (MILK) why should a consumer buy software (COW)?

Basic Structural Modeling

Basic Structural Modeling Classes Relationships Common Mechanisms Diagrams Classes are the most important building block of an object oriented system. A class is a description of a set of objects that share the same attributes, operations, relationships and semantics. A class implements one or more interfaces. Classes are used to capture the vocabulary of the system you are developing. Classes may include abstractions that are part of the problem domain.

Introduction to Software Engineering

Evolving Role of Software Hardware vs. Software Software characteristics Changing nature of software Evolution of Software Software Myths Software is a product Transforms information - produces, manages, acquires, modifies, displays, or transmits information Delivers computing potential of hardware and networks Software is a vehicle for delivering a product Controls other programs (operating system) Effects communications (networking software) Helps build other software (software tools & environments)

Bandwidth Utilization: Multiplexing and Spreading

Bandwidth utilization is the wise use of available bandwidth to achieve specific goals. Two categories: multiplexing and spreading Efficiency can be achieved by multiplexing Privacy and anti-jamming can be achieved by spreading. Whenever the bandwidth of a medium linking two devices is greater than the bandwidth needs of the devices, the link can be shared. Multiplexing is the set of techniques that allows the simultaneous transmission of multiple signals across a single data link.

Structured Query Language (SQL)

SQL is the most widely used commercial relational database language THE FORM OFABASIC SQLQUERY SELECT [DISTINCT] field names FROM table names WHERE condition SELECT clause contains fields to be displayed in the result FROM clause contains table names Optional WHERE clause contains conditions on the tables mentioned in the FROM clause. Used to check whether an attribute value matches a value contained within a set of listed values

8086 microprocessors

A microprocessor is a computer processor that incorporates the functions of a computer's central processing unit (CPU) on a single integrated circuit (IC).  The microprocessor is a multipurpose, programmabledevice that accepts digital data as input, processes it according to instructions stored in its memory, and provides results as output Bit A digit of the binary number or code Nibble The 4-bit binary number or code Byte The 8-bit binary number or code Word The 16-bit binary number or code Double Word The 32-bit binary number or code Data The quantity operated by an instruction of a program is called data. The size of the data is specified as Bit, Byte,Word…….. Address The address is an identification number in binary for Memory locations. The 8086 processor uses 20-bit address for memory. Bus A bus is a group of conducting lines that carries data,address and control signals. Introduced in 1978 . Comes in Dual-In-Line Package(DIP) IC. 8086 1s a 16-bit microprocessor . Works on 5 volts power supply. It is built on single semiconductor chip and packaged in an 40-pin IC. It has 20-bit address bus and 16-bit data bus. It can directly address upto 220 I.e., 1M bytes of memory. The maximum internal clock for 8086 is 5MHz

Natural Resources and Their Importance

Natural resources are materials and components that can be found within the environment. They are naturally occurring substances that are considered valuable in their relatively natural form. 1. Based on origin: Biotic: Obtained from the biosphere Ex: Fossil fuels such as coal and petroleum Abiotic: Obtained from non-living or non- organic material. Ex: land, fresh water, air and heavy metals (gold, iron, copper, silver)

Ecosystem and It's Importance

Contents Definition Scope and Importance of ecosystem. Classification, structure and function of an ecosystem Food chains, food webs and ecological pyramids. Flow of energy Biogeochemical cycles Bioaccumulation Biomagnifications Ecosystem value, services and carrying capacity. Environment is the physical and biotic habitant (living place of organisms) which surrounds us; that which we can see, hear, touch, smell and taste. Environment = Physical Environment (Non-living system which includes water, land, air) + biological environment (which includes plants, animals and microorganisms)

Transmission Media & Switching

Guided Media Unguided Media: Wireless Transmission media are actually located below the physical layer and are directly controlled by the physical layer. We can say that transmission media belong to layer zero. A transmission medium can be broadly defined as anything that can carry information from a source to a destination. The transmission medium is usually free space, metallic cable, or fiber-optic cable. In telecommunications, transmission media can be divided into two broad categories:
