What are the key concepts in project management, digital logic, software engineering, databases, and computer hardware?

Here are the solutions to the computer science questions: 36. Sequence of dependent tasks that determine the project earliest Completion date: The sequence of dependent tasks that determines the project's earliest completion date is known as the critical path. C. Critical path* 37. Which gate is the same as an OR gate followed by a NOT gate? An OR gate followed by a NOT gate is a NOR gate. C. NOR* 38. Validation and Verification techniques are used to ensure: Validation and Verification (V&V) techniques in software engineering are primarily used to ensure the correctness of a system, meaning it meets its requirements and is free from defects. D. Correctness* 39. It enhances the collection, access and management of interrelated data: A Database Management System (DBMS) is software designed to manage and organize data in a database, facilitating its collection, access, and management. B. DBMS* 40. When HDD is replaced with SSD, it results in: Solid State Drives (SSDs) use flash memory, which allows for significantly faster data access compared to traditional Hard Disk Drives (HDDs) that rely on spinning platters. A. Faster data access* 41. What is the required memory Space in MB to store 2GB of data? Step 1: Recall the conversion factor between GB and MB. 1 GB = 1024 MB Step 2: Convert 2 GB to MB. 2 GB = 2 × 1024 MB = 2048 MB C. 2048MB* 42. A type of Maintenance applied to the computer to anticipate future errors and technical problems is called Preventive maintenance is performed regularly to reduce the likelihood of future failures and anticipate technical problems. D. Preventive maintenance* 43. The full meaning of the acronym PDF is PDF stands for Portable Document Format. A. Portable Document Format* 44. The on demand and delivery of Computer Services over the Internet is referred to as? The on-demand delivery of computer services, including servers, storage, databases, networking, software, analytics, and intelligence, over the Internet is known as Cloud Computing. C. Cloud Computing* 45. Virtual memory is used to: Virtual memory is a memory management technique that allows a computer to compensate for physical memory shortages by temporarily transferring data from RAM to disk storage, effectively extending RAM. B. Extend RAM* 46. Consider the table below, | ID | NAME | SUBJECT | |----|------|---------| | F3 | Mercy | Chem, Bio | | F4 | John | Math, ICT | How many records and Fields are found on the table above? • Fields are the columns in a table. In this table, there are three fields: ID, NAME, and SUBJECT. • Records are the rows of data in a table. In this table, there are two records: (F3, Mercy, Chem, Bio) and (F4, John, Math, ICT). Therefore, there are 3 fields and 2 records. C. 3 fields and 2 records* 47. The Amount of time a task can delay without a delay in a project Completion date. This definition refers to slack time (also known as float) in project management, which is the amount of time an activity can be delayed without affecting the project's overall
