Define fixed length fields?
Fixed length fields are columns in a database table that always use a set amount of space for each row of data in the table. A fixed length field of 50 characters will always consume 50 characters for that field, regardless of how long the actual data in that field requires. Fixed length fields typically use more storage resources than variable length fields, but they are a bit faster for the processor to work with, since the length only needs to be determined once. Fixed length fields are appropriate for data where the length is constant. Some examples of fields that are good candidates for fixed length fields include Social Security Numbers, fixed length postal codes/ZIP Codes and telephone numbers (provided international data is unexpected.) Data that varies in length should be stored in a variable length field, as it will take less physical storage space and will not need to be truncated to remove extra spaces.

What are the advantage of using fixed length fields instead of variable length fields in a database?
A fixed length field is one which contains a set number of characters.With fixed length fields, the fields may need to be padded out to the right length, eg with characters.eg If a Surname field is set at 10 characters then the name SIMPSON would need 3 s added on to the end of it.Advantage - Every record is the same size, so it is possible for the computer to calculate exactly where each record starts in the file and therefore it is quicker for the computer to find a particular record.

Why does the TCP header have a header length field and UDP header does not?
in tcp header (32 bits) we have a field that is called options and padding that has variable in length and the header length shows the actual header size i.e size of 20 octets+size of options and padding field and in UDP we dont have any field like that and its header is fixed of 8 OCTETS (32 bits header size) refrence: WIRELESS COMMUNICATIONS AND NETWORKS by William Stallings Second Edition pg 91(see fig)

What would be an appropriate data type to choose for a fixed-length field designed to hold a person's name?
A string data type with a fixed length would be appropriate for storing a person's name in a fixed-length field. This ensures that all names are stored uniformly and can accommodate the longest expected name in the field.
