1. The process of accessing information on a floppy disk is

a. random.

b. serial.

c. semirandom.

2. The operating system of a computer is defined as

1. hardware that operates the floppy disk.
2. a program that manages files on the disk.
3. a group of programs that manages and directs hardware and software in the system.

3. The Editor is

1. an assembly language program that reads and writes information on the disk.
2. a high-level language program that allows the user to edit programs.
3. a program that allows the user to write, modify, and store text in the computer system.

4. The Assembler is

1. a compiler that translates statements from high-level language into assembly language.
2. a program that translates mnemonics into binary code.
3. an operating system that manages all the programs in the system.

5. A file is

a. a group of related records stored as a single entity.

b. a program that transfers information between the system and the floppy disk.

c. a program that stores data.

6. The COM (TSK) file

1. consists of Hex digits and is used for communication.
2. is the only file that can be interpreted and executed by the microprocessor.
3. consists of Z80 mnemonics.

7. The Hex file generated by the Assembler is used primarily

1. to reduce the memory requirement for storing files.
2. to transfer a file from one system to another.
3. to transfer a file between a floppy disk and the system’s R/W memory.

8. The assembler directive DB (or DEFB)

1. reserves a specified number of memory locations.
2. stores data bytes written after the directive in successive memory locations.
3. defines bytes as decimal, Hex, or Octal.

9. A disk controller is

1. a program that manages the files on the disk.
2. a circuit that interfaces the disk with the microcomputer system.
3. a mechanism that controls the spinning of the disk.

10. The MS-DOS is

1. an operating system that is designed primarily to handle the communication between the l6-bit microprocessor and its peripherals.
2. a master disk that stores all system programs.
3. an application program that handles communication between various systems.

11. Assemble the following program with the starting address l820_H, and print the LST file. The address of the output port OUTPRT is 07_H•
