It uses it's routing table. If the destination is on the same network, it transmits directly via the MAC address. If the destination is on another network, it transmits to whatever the table says for that network. For desktops it's usually a default address of the router on the computer's network.

Answer: Indexed
Explanation: Indexed property in the database system is for indexing .In this process reduction of the record/disk numbers results in the increase in the optimized performance. The structure of the index is in column form.
This technique rapidly provides the data from the table containing database when every query arises or requirement is proposed. Therefore the efficiency of the database increases.
Other options are incorrect because validation rule and text are regarding the verification of the data user and text respectively and expression is defined as the group of one or more value.Thus the correct option is indexed.
Answer:
Multiprogramming
Explanation:
<u>Multiprogramming:</u> In a modern computing system, there are usually several concurrent application processes which want to execute. Now it is the responsibility of the Operating System to manage all the processes effectively and efficiently.
One of the most important aspects of an Operating System is to multi program.
In a computer system, there are multiple processes waiting to be executed, i.e. they are waiting when the CPU will be allocated to them and they begin their execution. These processes are also known as jobs. Now the main memory is too small to accommodate all of these processes or jobs into it. Thus, these processes are initially kept in an area called job pool. This job pool consists of all those processes awaiting allocation of main memory and CPU.
CPU selects one job out of all these waiting jobs, brings it from the job pool to main memory and starts executing it. The processor executes one job until it is interrupted by some external factor or it goes for an I/O task.
Hexadecimal numbering system contains 0 through 9 plus letters "A'' through "F"
Explanation:
Before I explain what Hexadecimal is, it is good that we understand what base 10 number system is. Base 10 number system which is also known as the decimal number system has 10 digits that we count from 0 all the way through 9 (0-9). It is the standard numerical system that is used most often. If we took the base 10 numerical system and combined it with six extra symbols, we normally get the hexadecimal number system.
Hexadecimal number system is heavily used nowadays. It is a base-16 number that uses a possible 16 digits representation. The combination of base 10 numbers and an extra 6 digits helps create large hex numbers. Thus, this means hex uses the standard 0-9 combined with 6 digits taken from the alphabet A-F (A, B, C, D, E, and F). So instead of representing the numbers 10 to 15, we use A-F to represent the decimal values 10-15. In short we should get something like (0 1 2 3 4 5 6 7 8 9) (A B C D E F).
