Part 4: Computer Systems & Networking (Paper 1 continued)

This section of the 2026 Mock GCE covers industrial computing, hardware architecture, and communication protocols.

Industrial Computing: The main purpose is to control and monitor industrial processes.
Input Devices: Out of the options provided (Plotter, Speaker, Scanner, Projector), the Scanner is used to enter data into a system.
System Software: Responsible for managing hardware resources (unlike application software used for posters or videos).
Device Drivers: Required so the operating system can detect and control connected devices.
Microcontrollers vs. Microprocessors: A microcontroller differs because it includes CPU, memory, and I/O on one single chip.

Transmission Media: * The term refers to the path through which data travels.
- An example of unguided (wireless) media is Radio waves.
Transmission Modes:
- Serial Transmission: Sends bits one after another on a single line.
- Full-duplex: Allows data transmission in both directions simultaneously.
Protocols: Mainly responsible for defining the rules for data exchange.
Topologies: The Star topology connects all devices to a single central device (hub/switch).

Based on Figure 1 in the exam paper:

Wired Network Connection: The port used to connect a computer to a wired network is the RJ45 port (indicated as number 3 in the diagram).
External Ports: The RJ45 is the primary port for wired LAN cables, whereas HDMI and VGA are for video, and USB is for general peripherals.

Relational Databases: * A record corresponds to a complete row in a table.
- A foreign key is primarily used to link related tables together.
Computer Architecture: The Harvard architecture is characterized by using separate memory spaces for programs and data (distinct from the Von Neumann architecture).

Utility Software: Designed to maintain and protect the computer system (e.g., antivirus, disk defragmenters).
