Explanation

The continue statement skips the remaining code inside the loop for the current iteration.

It then shifts control back to the beginning of the loop for the next iteration.

Explanation

A database is a collection of logically related data sets or files that are organized for efficient storage, retrieval, and management.

It allows easy manipulation and querying of data through systems like SQL.

Explanation

In z = z + y;, since z is an int and y is long, y is converted to int (if possible) to match the type of z due to usual type conversion rules.

The result is calculated as an int, and this may cause data loss if y exceeds int range.

Explanation

1 PB = 1,000 Terabytes

1 TB = 1,000 GB

So, 1 PB = 1,000 × 1,000 = 1,000,000 GB

Explanation

The Interface Message Processor (IMP) was the first device used to connect computers in the early ARPANET, the precursor to the internet.

It acted like a packet-switching node, similar to modern routers.

Explanation

A Database Administrator (DBA) is responsible for the design, implementation, maintenance, and repair of a database.

They ensure that the database operates efficiently, securely, and reliably.

Explanation

In a do-while loop, the body executes first, and the condition is checked afterward, ensuring it runs at least once.

This differs from for and while loops, which check the condition before executing.

Explanation

"define" is a reserved keyword in C, used in preprocessor directives (e.g., #define) and cannot be used as a variable name.

Variable names like "address", "name", and "age" are valid as they follow C naming rules and aren't reserved.

Explanation

The Operating System (OS) keeps track of the location, names, and structure of all files stored on a computer.

It manages the file system, ensuring users and programs can access and organize data efficiently.

Explanation

Resolution is commonly measured in pixels per inch (PPI) or dots per inch (DPI) for screens and printed images.

Higher PPI/DPI means better image clarity and detail.
