TrueCrypt Advantages

One advantage to using TrueCrypt on your PC is that it Encrypts data "on-the-fly." This means that data will be encrypted and decrypted much faster than previous encryption schemes. Encryption will be faster and less time-consuming. However, the PC still needs to process the encryption command, so it won't be as fast as a computer without TrueCrypt. Another advantage is that TrueCryot uses special coding that is given to the user so that the device doesn't need to be used on a specific computer and data can be transferred easier. However, if the user forgets their password, then they will not be able to retrieve their data and will have to spend time figuring out how to change or recover their password, or their data will be as good as lost. A third advantage is that the user's data will be encrypted so that no one else can use it. This protects personal information from being stolen. however, if the user's password is stolen and the hacker also has or is familiar with TureCrypt, then they can steal the password and access the uer's information. However, this would take longer than stealing unprotected information, and having to tak ethe extra time may discourage a hacker and cause them to look for a different victum.

ATM advantages

One advantage of using an ATM is that an ATM is available longer. A person doesn't need to wait for any specific time of day to go to an ATM, whereas they do need to wait in order to go to the bank. This is good because people can access the services of an ATM at many more times of the day than at a bank, and thus is more convenient for the user. Another advantage is that an ATM is less pronged to human error. Getting helped by a bank employee has its benefits, but the service is pronged to human error, and can be very inconvenient if not caught right after the error is made. An ATM, being a programmed machine, is less pronged to random error, although it is not completely error-free. Humans built this device, and so there exists a possibility of a programming error, causing error on a much wider scale. However, these errors can be caught and fixed more easily, as certain trends that have to do with the error are much easier to spot and it is much easier to reprogram a machine sometimes than it is to correct a human error. A third advantage is that transactions made by an ATM are much easier to keep track of than by a human teller. A human must manually record the transactions he or she made, and sometimes this can lead to an incorrect recording due to human error or poor memory. However, an ATM is programmed to record every transaction it makes, and, given that the device has been programmed correctly, these records will not be incorrect or pronged to error as much as if a human were recording. An ATM is a machine, and has no emotions, making it less likely to make an error in a transaction. There are quite a few advantages to using ATMs, but they are not without their disadvantages.
