A company's identity is the visual manifestation of the company's reality as conveyed through the organization's name, logo, motto, products, services, buildings, stationery, uniforms, and all other tangible pieces of evidence created by the organization and communicated to a variety of constituencies. Image is a reflection of an organization's identity, so it is the organization as seen from the viewpoint of its constituencies. Image can vary among constituencies, and advertising is helpful to get people to adapt the image that the company wants to have. A company can have different images. A company's identity and image are two of the most critical components the corporate communication function has to deal with. When an organization's identity and image are aligned, the foundation for a solid reputation exists. The image and identity of a company also helps the company differentiate itself from others in the eyes of their constituents.

Reputation differs from image because it is built up over time and is not simply a perception at a given point of time. It differs from identity because it is a product of both internal and external constituencies, whereas identity is constructed by internal constituencies (the company itself). Reputation is based on the perceptions of all constituencies.In the changing environment for business, corporate philanthropy and social responsibility are gaining visibility and importance in the eyes of many constituencies. A company that has a good understanding of its own constituencies and what is important to them, and that gives thought to how to tie such programs into its corporate vision, will be well positioned to create programs that will enhance reputation.
So the corporate should take care of their identity, image, and keep the communication well to make sure they can provide good product and service to keep the high reputation.
What i have learnt from my personal experience is that the first impression/appearance/contact with any company is extremely important. When I interact with a company for the first time and something goes awry, I tend to have a negative image of the company and will try my level best to avoid contacting the company again. This happened to me with Sify Inet India. I had gone to Sify's office to apply for a new internet connection. What I witnessed over there was that all the people working there were very unorganized and took a lot of time to do anything and everything like getting application forms, clearing my doubts etc. This inturn lowered the image of the company in my mind and thus I not only did not take the connection but I even asked my friends to avoid Sify.

Lasswell, a political scientist, provided a general view of communication that extended well beyond the boundaries of political science. He said that the communication process could best be explained by the simple statement: "Who says what to whom in what channel with what effect." Both Aristotle and Lasswell viewed communication as a one-way process in which one individual influenced others through messages. The addition of the channel as a component was a response to the growth in new communication media, such as print, the telegraph, the radio, etc. Lasswell's approach also provided a more generalized view of the goal or effect of communication than did the Aristotelian perspective.
The information source selects a desired message out of a set of possible messages. The selected message may consist of written or spoken words, or of pictures, music, etc. The transmitter changes the message into the signal which is actually sent over the communication channel from the transmitter to the receiver. Shannon and Weaver introduced the term noise. Noise was used as a label for any distortion that interfered with the transmission of a signal from the source to the destination, such as static on a radio, rain-soaked pages of a newspaper etc.
