What is accurate about fast-forward switching?
The switch stores the first 64 bytes of the frame before forwarding.
When a student begins a new reading assignment what should he or she do first?
he or she first open the book and reading assignment
What is fragment free switching?
Fragment free is a variation on cut-through switching that partially addresses this problem by assuring that collision fragments are not forwarded. This will hold the frame until the first 64 bytes are read from the source to detect a collision before forwarding.This is only useful if there is a chance of a collision on the source port. Fragment-free switching is also known as runtless switching and is a hybrid of cut-through and store-and-forward switching. Fragment-free switching was developed to solve the late-collision problem.

What type of switches propagate flawed packets and can contribute to greater network congestion?
Any switch that does not support store and forward can potentially propogate flawed frames/packets and contribute to network congestion. There are 3 Main types of switching: Store and Forward - Stores the entire frame, runs a crc check and forwards the frame if no errors are found. Most reliable, but has somewhat high latency. Fragment Free Switching - begins to forward the frame after the first 64 bytes of the frame if they are error free. Most errors will occur in the first 64 bytes, so this is generally a preferred compromise of speed and reliability. Cut Through - Forwards frame immediately after first 14 bytes are received. This provides extremely low latency and can be helpful in some environments like an iSCSI SAN. However when using cut through in a mission critical environment you want to make sure cabling and configuration are all optimum. It is a good idea to periodically check interface statistic for errors, and resolve any significant errors you find.
HOW TO USE A micrometer?
First calibrate the micrometer by dialing the spindle to zero and adjusting the anvil until it is flush against the spindle. Measure the screw until the ratchet begins to click and take the first reading. This reading can then be compared to a machining book to verify the pitch diameter.
What is 816.67mb plus 3.23gb equals?
First of all, I am going to assume you mean MB and GB and not Mb and Gb. There are two answers to this, because drive manufacturers use powers of 10 and computer scientists use powers of 2. Using powers of 10: 1MB=1,000,000 Bytes and 1GB=1,000,000,000 Bytes 3,230,000,000 Bytes + 816,670,000 Bytes = 4,046,670,000 Bytes ~= 4.047 GB Using powers of 2: 1MB=1,048,576 Bytes and 1GB=1,073,741,824 Bytes 3,468,186,092 Bytes + 856,340,562 Bytes = 4,324,526,654 Bytes ~= 4.124 GB

To read data which is superior 1. input stream 2. file reader?
First of all, these two classes are on different levels of abstraction. An InputStream is used for reading any stream of bytes, while a FileReader is used to read characters from a file. If you want to ask between a FileInputStream and a FileReader, then we need to look at what type of data you are reading. If you're reading plain-text file, for example, you want to use a FileReader because it was designed to read in characters. For other types of data, the FileInputStream would be better, as it is used to read in generic streams of bytes from a file.
Who invented the automatic switching system?
The first automatic switching system was introduced at the 1881 Paris Electrical Exposition, and a workable system had been patented by 1889.
