  • LAN (Local Area Network): Covers small geographic areas such as an office, home, or computer laboratory.
  • MAN (Metropolitan Area Network): Spans a town, campus, or municipality.
  • WAN (Wide Area Network): Spans countries or continents (e.g., the Internet).
  • PAN (Personal Area Network): Short-range connection around an individual (e.g., Bluetooth).
• Network Topologies:
  • Star Topology: Devices connect to a central hub/switch.
  • Bus Topology: Devices attach to a single backbone cable terminated at both ends.

Strategic UTME Computer Studies Exam Preparation Tips

2027 JAMB UTME Updated Computer Studies Syllabus

• • Study with the Syllabus: Align your daily reading directly with the topics outlined in the official syllabus instead of reading textbooks randomly.
  • Practice CBT Environment: Computer Studies in JAMB is written via Computer Based Testing (CBT). Familiarize yourself with keyboard navigation, basic shortcuts, timer management, and mouse operations.
  • Master Logic Gates & Binary Conversions: Spend time practicing manual conversions between Binary, Denary (Decimal), Octal, and Hexadecimal number systems, as well as evaluating truth tables.
  • Review Past UTME Questions: Solve at least 10 to 15 years of past JAMB Computer Studies questions. Take note of recurring questions on computer generations, network devices, system software, and memory types.
