Asynchronous and Synchronous Essay Example for Free

Asynchronous and Synchronous Essay A bit is a singular digit represented by a binary number. A character is represented in computing terms but a code called ASCII There are 7 bits to an ASCII number With parity bit added there are 8 bits, parity is added to aid in error detection. 8 bits is equal to a byte. 1 1 0 This diagram represents an 8 bit binary number (1byte). The step represents a 1 and the flat part represents nothing. This number would then look like this, 100000001. In ASCII this represents the character A. Packet Structure Instead of sending singular characters it is possible to send many in one go, this is called a packet. For example we use the ASCII code to represent a sentence and this may take up to 50 characters. When sent in the form of a packet we must split the packet up, this is done by using control characters. The control characters are; SYN = Synchronise STX = Start of text ETX = End of text Above is an example of a packet structure used with Asynchronous sending. Bit and Baud Rate When the term bit rate is used, it means the amount of bits per second that are sent. A single character is to be sent for example, the character is ASCII code is made of 7 digits and a parity bit and this is called the useful data. The standard speed for transmission sending is 8bits a second. This number or ASCII code that is sent will not only comprise of the 7 bit and parity, it contains a start bit and an end bit to represent where the character starts and stops. The bit rate is then combined to include these two extra bits and this is called the baud rate, this would then be 10 bits a second (8+2). Start bit Stop bit Parity bit Asynchronous and Synchronous Asynchronous communications do not depend on the synchronisation of a transmitter or a clock. It can be said that they are never independent. When sending individual characters there is no need for synchronisation at all. Asynchronous has a very simple interface and the data rate is normally at 64kbps. It can be used for connecting Printer, Terminal, Modem and home connections to the internet. Asynchronous protocol was one of the first around and was popular with the early invention of the tele typewriters. It requires the use of start and stop bits as previously said and this provides byte timing and overhead. No clocks are needed and a parity bit is also sent to help with error detection. Asynchronous transmission will send single bits of data at a time. There is a standard for this form and it is called RSC323C. Asynchronous represents negative voltage as 1 and positive voltage as 0. Information is sent in a packet with the start and stop bit plus parity for error detection. This method of transmission is suitable for low speed. This is because for every character that is sent a further 2 bits (start and stop) must be added. For example, 1000 characters are to be sent, there are 8 bits per character plus a start and stop for each thats a total of 10000 bits. This is very in efficient. Its packet structure is known as a packet frame. Asynchronous Transmission Start bit Stop bit Parity bit The synchronous transmission form occurs when bits are sent in the packet form. This form of data sending is normally sent through bigger Networks. To calculate the efficiency you must divide the bit rate by the baud rate and then multiply by 100. Synchronous communication is far more efficient than its counterpart. To start, there is no need for a start and a stop bit. This time however the data is grouped, and then sent with characters and the start and the end of the packet. This can be seen above with the syn x 3 which stands for synchronisation idol, stx for start of etx and etx for end of text. Synchronous can achieve much higher speeds than asynchronous and is preferably used within large network structures. It would be therefore worth bearing in mind that if large amounts of data were to be sent then the synchronous form would be far better. Less overhead means greater efficiency and asynchronous just cannot match this. However asynchronous does have its benefits and would be deemed worthy of smaller data packets. Its the lack of timing information sent with the data which restricts it so greatly. Synchronous Transmission Packet of data Effect Of Bandwidth Limitation And Noise Bandwidth is the sum amount of data being sent to a recipient in a given time through a form of communicational media. This sum is normally represented on bit per second. Bandwidth also has an alternative meaning and can represent the differing frequency ranges. All media types have their own forms of bandwidth limitation; this means we cannot transmit the same things on the differing types of media at the same speeds. If sending something with 10bits it will be sent at 10bits a second. This should apply for the bandwidth also (10 bits a second) however; it can be affected by something that is known as cross talk. This is interference on the line, also known as noise. Noise can occur in many forms and this will always affect speed. The only method of transmitting data without any electrical noise affecting it is by using a fibre optic cable. Fibre optic cables uses the use of light and mirrors, this is why it can not be affected. However it is also very expensive.

Tourettes Syndrome and the :: Biology Essays Research Papers

Tourette's Syndrome and the "I" Function Tourette's syndrome is characterized by a presentation of verbal and motor tics. The first descriptions of the syndrome, involving symptoms similar to Tourette's, were reported in the nineteenth century. For most of the twentieth century TS was thought to be a psychiatric disorder because of the ability the patients had to suppress their tics. In the past twenty years more biological factors have been introduced in the study of the syndrome, arising from the use of pharmacological treatment and the discovery of hereditary patterns of the disorder. In the diagnosis of Tourette's Syndrome the concept of involuntary tics has become hard to define. Many patients experience a volitional aspect of the tics, "a capitulation to an internal urge for motor discharge accompanied by psychological tension and anxiety Patients who are afflicted with Tourette's syndrome can only describe their symptoms by using terms associated with the "I" function, the consciousness of self and relation to one's environment, and many of their symptoms are associated with or affect the function of their self. This can imply that what ever is causing the symptoms of Tourette's is subsequently affecting the part of the nervous system that controls the self and the "I" function. Most of the studies done on the neuropathology of Tourette's syndrome (TS) have been focus on the basal ganglia, a group of nuclei located mostly in the diencephelon of the brain, a region beneath the cortex. This area has been classically associated with involuntary movement and tic disorders such as Parkinson and Huntington's disease. The neural circuits formed by the basal ganglia and the thalamus are critical for normal function and hypothesized to be required for the planning of movement ranging from simple to complex. Though what these pathways actually do is still very vague the basal ganglia has been found, in normal circumstances, to exert an inhibitory influence on the thalamus. Disruption of this inhibition could correspond with TS in which the making of uncontrolled and unplanned movements are involve. There is evidence that patients with Tourette's syndrome have some structural abnormalities in the region of the basal ganglia, mainly TS patients showed a comparative size reduction in the basal ganglia. There are various different behaviors through which Tourette's syndrome presents itself. The diagnostic categories of TS depend on the presence of tics, alone, although patients with Tourette may have mental or behavioral disorders, which over shadow the severity or impairment on normal function of the tics.

Any form of exchanging information between people or groups of people is referred to as communication. For any cooperate to achieve effective organizational change, internal communication is very important. Research indicates that employees in lower levels are usually ignored while making organization’s decisions. It was also found out that the employees become alienated especially when the decision is aimed at initiating a change in the organization. As a way of fostering employee productivity, effective internal communication is therefore very important.This does not downplay the vital role of external communication in an organization but both must be balanced. The up and down or horizontal internal communication- as in the case of Vodafone- helps the employees in understanding what they are expected of them and taking the necessary steps in ensuring their work is completed on time. (http://www. thetimes100. co. uk/downloads/vodafone/vodafone_12_full. pdf ) Internal communic ation can also be verbal or written. The vital role of internal communication involves explaining organization’s values, culture as well as visions to employees for them to make informed decisions.It will also strengthen employee relationship and enhance their sense of belonging. For example; ‘eVelopers internal communication system was developed and implemented to ensure that all employees are informed about all corporate policies, strategies, decisions, updates, news, changes, etc. and properly apply them, increasing the efficacy of company performance. ’ http://www. evelopers. com/qm5 This paper examines cooperate meetings as one of the internal communication processes in an organization. Participant selectionCooperate meetings have proofed to be very successful especially where the organization succeeds to invite the right participants. This can be done by conducting extensive consultations with the employees from different departments in an organization. Thi s will however depend on the reason as to why the meeting should be held. After making a decision about whom to invite, it is very important for them to be briefed on the purpose of the meeting. They should also be informed on where, when, the expected participants and where to make further enquiries if they needed to do so.It was found out that the conditions or the environment surrounding the meeting’s venue highly determines whether the meeting will be a success or not. The venue should be comfortable enough to win the concentration of the participants. When setting the date and time care should be taken to ensure that every participant is comfortable. Religious, gender and cultural diversity among the employees should be considered, failure to which the participants may pay little or no attention to the proceedings of the meeting.True representation of the organization in the meeting should be demonstrated by including employees or their representatives from all departmen ts. (http://www. managementhelp. org/misc/mtgmgmnt. htm ; Quirke B, 2000, pp. 25-61) Agenda development The meetings agenda should be made known to all expected participants. Research indicates that no effective meetings agenda can be developed without adequate consultations among all the concerned parties. The key participants should help in identifying feasible outcomes and what ought to be done to ensure the identified target outcomes are reached.It is very important for every meeting to have an overall outcome. For instance, increasing sales, improving quality of products or service, conflict resolution, management and transformation, and introducing change among others. The agenda should clearly indicate how the participants should be kept busy especially those who arrive earlier than stated. It is very important to ensure that all topics are listed together with their respective action or expected output. Opening meetings Punctuality is always very important in any meeting.Mee tings should therefore start on the scheduled time. Acknowledging the presence of participants who dedicate their time to attend the meeting encourages them and enhances the sense of meaning in whatever goes on in the meeting. It is also very important to review the meeting’s agenda in order to consider any possibility of making any amendments. Meeting participation and evaluation Every one should be given an opportunity to participate actively. This can be done through use of questions, opinions, votes, demonstrations and individual presentations.Discursions should revolve around the agenda items. The meetings should be made as lively as possible to help the participants to open up and give their views without fear or favor. The appropriate momentum should be maintained. Participants should be asked to evaluate the progress of the meeting from time to time in order to ensure the correct pace is maintained. An effective meeting must be successfully concluded. Participant conf identiality must be guaranteed. Soon after conclusion, the overall evaluation must be done.This will help in setting a date for another meeting if need be and decide on its agendas. Proceedings of the meetings should be recorded and every participant should get a copy at the end of the meeting. Further development Even though cooperate meetings have been held by many organizations over the past, there is still need to improve them in order to reap their full benefits. It is very unfortunate that the physically challenged have been neglected during cooperates meetings.The deaf and the dump should not be ignored. Sign language should be introduced in order to enable such people with special needs to follow what the other participants are doing. Departmental meetings should be held before the actual meetings in order to bring the employees from a particular department together. This will save time and ensure that a true reflection of the status of the organization is portrayed. Meeting s involving many participants should be held in a room with adequate facilities but not in the open air.Some organizations address their employees in open-air meetings and their intention is not met due to disruptions from external factors. Audiovisual gadgets should be introduced to enable people to participate even from their offices. This will ensure that incase some senior officers are not able to attend -simply because they are out for other cooperate duties –they can participate in the meeting and provide appropriate responses when asked to. Since meetings are expensive, such a decision will reduce the number of meetings held especially when an urgent problem solution is required.This can be made possible by the use intranet. (Klein A, 2004, pp. 59) Depending on the purpose of the meeting, thorough consultations should be carried out from every department to ensure all underlying issues are tabled before the meeting. It is also good to invite at least one representative from those departments that are thought to be less concerned because an issue affecting a particular department affects the organization at large and needs cooperation in seeking for a long-lasting solution.It is expected that, in the future, cooperate meetings may take another dimensions and be transformed into be Parliamentary Procedures, which will involve the use of parliamentary laws. (http://www. jimslaughter. com/corporate. htm ) These parliamentary laws can be defined as; â€Å"the best method yet devised to enable assemblies of any size, with due regard for every member’s opinion, to arrive at the general will on the maximum number of questions of varying complexity in a minimum amount of time and under all kinds of internal climate ranging from total harmony to hardened or impassioned division of opinion.† http://www. jimslaughter. com/corporate. htm Conclusion Internal communication must however include all the other forms of internal communication processe s in order to ensure smooth running of the organization. These processes may be used interchangeably in order to ensure that information reaches the intended person at the correct time to enable proper action to be taken. References Slaughter, J. (1998).

Frankenstein Compare/Contrast Essay - 922 Words

Maddie Mills October 19, 2010 CPBL, 5 Frank. Compare/Contrast Victor Frankenstein The novel Frankenstein was written by Mary Shelley in 1818. This gothic romance novel tells the story of a philosopher who discovered how to create life, without the full knowledge that his actions could cause grave consequences. Universal Studios made the film version of this novel in 1931. Unfortunately, the film version of Frankenstein has more differences than similarities to the novel. In the novel, Victor’s mental obsession seems to be more severe than in the film. The character of Victor Frankenstein was portrayed in both the novel and the film as a veriphobe, or one who is afraid of the truth, in this case, the truth of his actions. He†¦show more content†¦Throughout his life, Victor is constantly frightened that the monster will come back for him. It is not until Elizabeth is killed that Victor overcomes his apprehension about the monster. He joins the villagers that are gathered outside and goes up into the mountains to search fearlessly for the monster. Victor goes out by himself and finds the monster. Victor doesn’t seem to be frightened when he confronts the monster, and ultimately is trying to kill him, which is similar to his motives at the end of the novel. Although the fearfulness and the change of motives are similar throughout the novel and the film, there are differences too. One difference that is seen in the variations between the novel and the film is the state of Victor’s mentality, and whether or not he has a complete obsession over his monster. While Victor is creating his monster in the novel, he does not receive any visitors. He does not have any assistants. He doesn’t even take time to reply to the letters sent by Elizabeth. During the creation of his monster, Victor goes into social withdrawal. Even after the monster is created, Victor seems to be obsessive compulsive about his monster. He becomes physically ill and seems to be mentally and physically unstable because of the escape of his monster. The only thing that he talks about or even thinks about during this time is the monster.
