Necrophobia specifically refers to the fear of death or dead things/dead bodies. Social Phobia is fear of social situations, Agoraphobia is fear of open spaces, and Claustrophobia is fear of confined spaces.

The CPU has two primary components: the Control Unit (manages instruction flow and data movement) and the Arithmetic Logic Unit (performs mathematical and logical operations). Registers are internal CPU storage, while main memory and bus are external to the CPU core.

Sequential access processes records in order (like magnetic tape), while random/direct access can retrieve any record directly by address (like disk). Indexed access uses an index to achieve random access. 'Online' and 'real time' describe system characteristics, not fundamental access methods.

Laser printers are actually quieter than impact printers (not a disadvantage), they are fast (not slow), and they produce high-quality output (not lower quality). Therefore, none of the listed options (A, B, C) are actual disadvantages of laser printers, making 'None of the above' the correct answer.

Buses are sets of parallel electrical conducting lines on a motherboard that link different components together, allowing data to flow between them. The CPU, memory, and peripherals all communicate via buses. Conductors is too general, connectors are physical interfaces, and 'consecutives' is not a technical term in this context.

Machine language (also called machine code) is the only language directly understood and executed by computers. It consists of binary instructions (0s and 1s) that the CPU can execute without translation. Application software and system programs are written in high-level languages that must be compiled or interpreted into machine language.
