It's a combination of software and hardware Which are embedded by Kiel compiler to perform desired task.

alternate answer:
Embedded systems refer to devices, instruments or large engineering structures/systems that are built to handle one or a few pre-established tasks. The computer controlling the whole thing is built into or 'embedded' within the device.

Selection Process

Selection is the process of choosing from a group of applicants those individuals best suited for a particular
position. Most managers recognize that employee selection is one of their most difficult, and most important,
business decisions. This process involves making a judgment -not about the applicant, but about the fit
between the applicant and the job by considering knowledge,skills and abilities and other characteristics required to perform the job Selection procedures are not carried out through standard pattern and steps in this. Process can vary from organization to organization some steps performed and considered important by one organization can be skipped by other organization.
Environmental Factors Affecting the Selection Process A permanent, standardized screening process could greatly simplify the selection process. However, development of such a process even if it were possible and desirable would not eliminate deviations to meet the unique needs of  particular situation.

Legal Considerations
Legislation, executive orders, and court decisions have a major impact on human resource management. It is important for hiring managers to see the relationship between useful and legally defensible selection tools.

Speed of Decision Making
The time available to make the selection decision can have a major effect on the selection process. Closely following selection policies and procedures can provide greater protection against legal problems; however, there are times when the pressure of business will dictate that exceptions be made.

Organizational Hierarchy
Different approaches to selection are generally taken for filling positions at different levels in the organization.

Applicant Pool
The number of applicants for a particular job can also affect the selection process. The process can be truly
selective only if there are several qualified applicants for a particular position. The number of people hired for a particular job compared to the individuals in the applicant pool is often expressed as a selection ratio.

Type of Organization
The sector of the economy in which individuals are to be employed private,  governmental, or not-forprofit can also affect the selection process.

Probationary Period
Many firms use a probationary period that permits evaluating an employee's ability based on performance. This may be either a substitute for certain phases of the selection process or a check on the validity of the process.

Selection Criteria
Mostly the selection of applicant depends upon the
following factors or criterions.
1. EDUCATION
2. COMPETENCIES
3. EXPERIENCE
4. SKILLS AND ABILITIES
5. PERSONAL CHARACTERISTICS

Applicant who is best fit should be hired instead of hiring a person with extra ordinary skills it means right person for right job should be hired person who is over or under qualified for the particular job will not be able to adjust in the organization.

STEPS IN THE SELECTION PROCESS
The selection process typically begins with the preliminary interview; next, candidates complete the application for employment. They progress through a series of selection tests, the employment interview, and reference and background checks. The successful applicant receives a company physical examination and is employed if the results are satisfactory. Several external and internal factors impact the selection process, and the manager must take them into account in making selection decisions. Typically selection process consists of the following steps but it is not necessary that all organization go through all these steps as per requirement of the organization some steps can be skipped while performing the selection process.
1. Initial Screening
2. Application Blank
3. Pre-employment Testing
. General Intelligence Tests
. Aptitude Tests
. Personality and Interest Tests
. Achievement Tests
. Honesty Tests
4. Interview
. Structured Interview
. Unstructured Interview
. Mixed Interview
5. Background Checks
6. Conditional job offer
7. Medical Exam/Drug Tests
8. Final Selection Decision

Proficiency in basic word processing software and internet is needed in a call center job as call centers generally use computers and the internet to reach the clients. It's time to toot your horn. If you are proficient in MS Office, then say it. If you took a diploma course in Computer Srudies, by all means, tell them.I have very good internet research skills.

(A question aimed at testing your sense of enthusiasm) Customer Service Representative job is chanllenging and streessful work because you deal with the customer directly. You need patience. In my previuos job I faced difficulty with customer critised me for the product. I tried to conviced the policy and about the product with polietly altimatly he agreed with my thought.

I was woking with non- profit organization at that time i phoned for fundrising. Really, I never forget that day gentleman told me that your voice is very soft and he impressed with my presentation. That was my one of the best experince at Call Centre

Firewalls can't protect very well against things like viruses or malicious software (malware). There are too many ways of encoding binary files for transfer over networks, and too many different architectures and viruses to try to search for them all. In other words, a firewall cannot replace security-consciousness on the part of your users. In general, a firewall cannot protect against a data-driven attack--attacks in which something is mailed or copied to an internal host where it is then executed.

Alternate Answer:
Properly configured firewalls can limit the propagation of worms - a form of malware.  Typically, firewalls are edge or parameter devices (separates network zones) and most viruses and malware targets end points (user workstations and servers).

Web 2.0 is a trend in the use of World Wide Web technology and web design that aims to facilitate creativity, information sharing, and, most notably, collaboration among users. These concepts have led to the development and evolution of web-based communities and hosted services, such as social-networking sites, wikis, blogs, and folksonomies (the practice of catgorising content through tags). Although the term suggests a new version of the World Wide Web, it does not refer to an update to any technical specifications, but to changes in the ways software developers and end-users use the internet.

In n-tier architecture the entire application is divided in several pieces. These pieces can be logical or physical. Each piece performs a specific task such as displaying user interface or data access. There can be any number of tiers or layers of such pieces. Hence, the name n-tier (Note that many times the terms tier and layer are used interchangeably). However, most commonly applications have 3 distinct tiers or layers. They are:

• Presentation Layer
• Business Logic Layer
• Data Access Layer

As you can guess, presentation layer is nothing but a piece of software that deals with user interface of your application. Displaying data to the end user and allow them to interface with it is the core functionality of this layer.

In most of the cases the data entered by the end user needs some kind of validation or further processing. This is the responsibility of Business Logic Layer.

Finally, your application data needs to be stored and retrieved in some data store (RDBMS, XML etc.). This task is handled by Data Access Layer.

In short, the process works like this:

• User requests for some application data.
• The data access layer retrieves the data and is forwarded to the presentation layer via business logic layer. Sometimes data access layer gives this data directly to presentation layer.
• Presentation layer receives the data to be displayed via business logic layer.
• The user changes the data and initiates the appropriate action (such as insert, or update).
• The business logic layer validates the data submitted by the user.
• If the data is valid it is handed over to data access layer for updating into the database.

Advantages of N-Tier ArchitectureAt first glance this division of tasks may seem to be unnecessary. However, it gives following benefits:

• The applications gets divided in logically isolated pieces reducing tight coupling between the UI, business processes and database.
• Change in the underlying database and data access methods do not have any effect on the presentation layer or client application.
• Client application no longer has SQL statements embedded in it. This makes it de-coupled from rest of the application.
• Table and column names can be effectively eliminated from the client-side code.
• The client application is unaware from where data comes (location transparency).
• It becomes easier to modify or extend your application, without breaking or recompiling the client-side code.

The downside of n-tier architecture is that you need to create many isolated classes and pieces of software. However, benefits of n-tier applications will far outweigh its disadvantage.

The .NET Framework class library is a library of classes, interfaces, and value types that are included in the Windows Software Development Kit (SDK). This library provides access to system functionality and is designed to be the foundation on which .NET Framework applications, components, and controls are built.

Software that provides services to access the Internet, an intranet, or an extranet. A Web server hosts Web sites, provides support for HTTP and other protocols, and executes server-side programs (such as CGI scripts or servlets) that perform certain functions. In the J2EE architecture, a Web server provides services to a Web container. For example, a Web container typically relies on a Web server to provide HTTP message handling. The J2EE architecture assumes that a Web container is hosted by a Web server from the same vendor, so it does not specify the contract between these two entities. A Web server can host one or more Web containers.
