Q1) Explain the concept of "perceived usefulness" in the context of technology acceptance model (TAM).
Answer: In the TAM model, "perceived usefulness" is defined as the degree to which individuals believe that use of a system will improve their performance. The perceived ease of use is the degree to which individuals believe that the system will be easy to learn and use. Both the perceived usefulness and ease of use can be strongly influenced by the expressed opinions of others who have used the system and the degree to which the organization supports use of the system (e.g., incentives, offering training and coaching from key users). Perceived usefulness and ease of use in turn influence an individual's attitude toward the system, which affect their behavioral intention to use the system.

A)True
B)False
Answer: False
Q3) _____ are responsible for maintaining the security and integrity of their organizations' systems and data.

The control unit sequentially accesses program instructions, decodes them, and coordinates the flow of data in and out of the ALU, the registers, the primary storage, and even secondary storage and various output devices. Registers are high-speed storage areas used to temporarily hold small units of program instructions and data immediately before, during, and after execution by the CPU.
