What is the fundamental difference between a compiler and an interpreter?
What is the fundamental difference between a compiler and an interpreter?
- An interpreter stops execution upon encountering an error, while a compiler continues processing. (correct)
- A compiler executes code line by line, while an interpreter compiles all code at once.
- A compiler produces an object file, while an interpreter generates an executable file directly.
- An interpreter checks for errors after generating intermediate code, whereas a compiler checks while compiling.

Study Notes
Secondary Storage Devices
- Store operating systems, device drivers, applications, and user data.
- Used for backup data, long-term archiving, and low-cost non-critical data storage.
- External drives, USB flash drives, and cloud storage are common forms.
- Cloud storage services include Dropbox, Google Drive, AWS, and Microsoft Azure, supporting the SaaS model.
Backup Storage Types
- Includes solid-state drives (SSDs), hard disk drives (HDDs), cloud storage, CD/DVD/Blu-ray drives, USB flash drives, SD cards, tape drives, and Zip/Jaz drives.
- Secondary drives are usually assigned letters from D: onwards, following historical DOS volume letter assignments.
System Configuration
- Refers to hardware, software, and processes that comprise a computer system.
- Includes both automatic settings and user-defined configurations.
- Specifies types, models of devices installed, and the software used.
Checking System Configuration
- To view hardware specs on a Windows PC:
- Click the Start button, go to Settings, click on System, then select About to see processor, memory, and system info.
Hard Disk Drives (HDD)
- Traditional storage component in PCs, now supplemented by SSDs but still prevalent.
- Modern HDDs are advanced with features like helium-filled enclosures for better performance.
- Uses rotating magnetic platters and read/write heads for data retrieval/recording.
Entering BIOS on Windows PCs
- BIOS initializes hardware before the operating system loads.
- Access BIOS by pressing the designated key during startup (e.g., F10, F2, F12, F1, DEL).
- Windows 10 also allows access through advanced start menu recovery settings.
NFC (Near Field Communication)
- Short-range wireless technology for data exchange (about 10 cm distance).
- Provides higher security than Bluetooth, ideal for crowded areas.
- Two types: Active (sends and receives data) and Passive (only sends data, e.g., student ID cards).
SATA (Serial Advanced Technology Attachment)
- Interface for data transfer between the motherboard and storage devices.
- Replaced PATA (Parallel ATA) for better speed and reduced interference.
- Serial communication enables simpler and slimmer cabling, enhancing performance.
Bluetooth Device Pairing
- To pair Bluetooth: Turn on the device and make it discoverable.
- Specific discoverability methods depend on the device.
- Pairing usually involves accessing the Bluetooth settings on a laptop.
Assembler
- Translates assembly language programs into machine code.
- Produces object files combining machine instructions and necessary data.
- Allows developers to manage computer hardware by interpreting assembly language into executable code.
