Question

the primary distinction between system software and application software lies in their functional purpose, which is defined as:
system software manages computer resources; application software is designe execute specific user tasks.
system software requires an internet connection; application software operates strictly in an offline environment.
system software is always proprietary and paid for; application software is consistently open - source and free.
system software handles data encryption; application software handles data archiving and physical storage.
a user runs an antivirus program to scan and clean potentially malicious files from the disk. this program belongs to which category of software?
core operating system (os) kernel software that directly manages the central processor unit.
application software, as it fulfills a specialized content creation task for the user.
utility program, which performs system maintenance and optimization tasks for th user.
proprietary middleware, which facilitates network communication between two different servers.
how many sequential bits are traditionally grouped together to form a byte, the standard unit used to encode a single text character?
four bits, which is the minimum binary string necessary to reliably transmit an audio signal.
eight bits, which is the necessary size for encoding one standard alphanumeric character.
sixteen bits, which provides the memory addressing scheme for most legacy application programs.
thirty - two bits, which is the base - level requirement for modern 64 - bit instruction

Explanation:

• For the first question: System software's main role is to manage computer resources (like the OS, device drivers). Application software is for user - specific tasks (e.g., word processing, antivirus scanning). The first option correctly states that system software manages resources and application software is for user tasks. The second option is wrong as neither system nor application software has a strict online - offline requirement. The third option is incorrect as system software can be open - source (e.g., Linux OS) and application software can be proprietary. The fourth option is wrong as data encryption and archiving can be done by both types depending on the software.
• For the second question: Antivirus programs are utility programs. They perform system maintenance (scanning for malware) and optimization (cleaning malicious files). The core OS kernel is more about basic system operations like process management. Antivirus is not for content creation. Middleware is for connecting different software components, not for antivirus tasks.
• For the third question: By definition, a byte is traditionally 8 bits. 4 bits is a nibble. 16 bits and 32 bits are larger units. 8 bits are sufficient to encode standard alphanumeric characters (e.g., ASCII uses 7 - bit for basic characters, but 8 - bit for extended ASCII).

Answer:

1. System software manages computer resources; application software is designed to execute specific user tasks.
2. Utility Program, which performs system maintenance and optimization tasks for the user.
3. Eight bits, which is the necessary size for encoding one standard alphanumeric character.
