Free example essay on Network Topologies:
In this type of network setup devices are connected with many redundant interconnections between network nodes. In a true mesh topology every node has a connection to every other node in the network. An advantage of this type of topology lies in the fact that it is relatively immune to bottlenecks and channel/mode failures. Allowing data to be rerouted around failed or busy nodes does this. A major disadvantage is high cost due to the high number of interconnections.
All devices are connected to a central cable, termed a bus or backbone. At each end of this cable is a terminating resistor, or a terminator. A signal gets passed back and forth between workstations and between the terminators. An advantage of this type of topology is that if one workstation fails, it does not affect the entire LAN. Another advantage is that it is easy to implement and cost efficient. A disadvantage to this type of topology is that it a connection to one of the workstations becomes loose, or a cable breaks, the entire cable segment loses connectivity.
Free sample essay on Computer Technology:
Since the beginning of time technology has helped us out as a human race. From the invention of the wheel to the Internet, technology has been a great factor on the way our civilization has grown. With more and more technological advances just around the corner, our civilization will continue to grow faster and faster than ever before.
Computers make life easier for people everyday. They help us to do tasks quicker and communicate with friends and family with the click on a button. Computers play a significant role in the school system as well. They help students to learn more efficiently and help them do their work. Computers offer the Internet which helps students research information for projects they may have. School computers also offer programs which can help anyone learn. An example of this is the program All The Right Type. This program helps students as well as teachers, to learn how to type faster and more efficiently. Also there are other programs which younger students can go on to help them with developing and reinforcing their math skills and reading skills. Programs like Math Circus and matching the word with the picture. Programs like these make it easy to understand and use computers, yet it also makes learning fun. Computers also make writing and doing homework easier to complete. With spell check and other spelling tools, it makes it easier and faster to complete work. This is because you are not spending all your time going through your homework looking for spelling mistakes, because the computer automatically does it for you, making your life easier.
Self-Presentation essay example:
The ability to manage impressions is an integral part in everyday life as individuals are able to alter people’s perceptions according to how one sees or wants to be seen by others. Self-presentation, also referred to as impression management, implies that an individual is monitoring how one is being perceived and evaluated by others and has considered the self-presentational implications of one’s behavior (Leary, Nezlek, Downs, Radford-Davenport, Martin, & McMullen, 1994). The amount of attention that people devote to their public images varies across situations and individuals. Some people are oblivious of others’ impression of them. On the other hand, there are people who are highly attuned to others evaluations and devote enormous amounts of effort to create the correct impression. A majority of people usually operate somewhere between these two bounds in that they tend to monitor at a moderate level on how they come across to others. However, in many situations people who are not monitoring or thinking about the impressions they are making can become quickly aware of others’ evaluative reactions (Leary & Kowalski, 1990).
The discrepancy between why in certain situations people are motivated to affect how others perceive them, and other times not is referred to as impression motivation (Tetlock & Manstead, 1985). Leary and Kowalski (1990) described impression motivation as being affected by three primary sets of factors: the perceived goal relevance of the person’s impressions, the value of the person’s desired goals, and the discrepancy between the person’s desired and current images.
Goal-relevance of impressions
The more important the attainment of a goal is to one’s self image, the more motivated people are to manage impressions to achieve that goal. People become more concerned with how others perceive them. Ferris and Porac (1984) researched some of the factors that would determine how relevant one’s impressions are to the fulfillment of their goals. Their results indicated that people set higher goals when others were present. In other words, the more public a behavior is, the more significant it is to manage impressions to accomplish that goal.
However, there are private behaviors that some people feel is necessary to self-present. Leary and Kowalski (1990) stated, “people may privately prepare to perform impression-relevant behaviors in public” (pg. 38). In some instances, people self-present in public settings so often that the actions become habitual, which may eventually carry over into their private behaviors.
