Understanding A+ Core Components: Motherboard, Connectors, and Hardware Setup Essentials

This guide covers the essential components of a computer's A+ core structure, including the motherboard (system board), CPU, RAM (DIMMs), expansion slots, and power supply. It delves into common connectors like DB, DIN, RJ, BNC, and audio types, along with key hardware devices such as sound cards, video cards, NICs, modems, printers, and joysticks. Additionally, it explains the use of jumpers and DIP switches in hardware configuration. Ideal for anyone looking to enhance their PC hardware knowledge.

Presentation Transcript

  1. Intro to the A+ Core • Motherboard - also called system board • CPU- calculations take place, needs cooled • RAM-DIMMS replacing SIMMS • Expansion slots- where devices attach • Power Supply- converts 115 volt to 3,5,12 volt • Floppy Drive-34 pin connector, twist in cable • Hard Drive- can be SCSI or IDE

  2. Six Most Common Types of Connectors for PC’s • DB- most common, male and female • DIN-always female, 2 sizes- DIN and mini-DIN • Centronics-contacts and no pins, SCSI • RJ- 2 types- RJ 11 for modems, RJ 45 for networks • BNC-also called coax connectors, fading in use • AUDIO- one type- mini audio

  3. Most Common Connectors

  4. Other PC Devices and their Connections • SOUND CARDS-convert digital to sound, and sound to digital • VIDEO CARD- 15 pin female DB connector. Easy to identify, always 3 rows of 5 pins • NIC-Network Interface Card. Usually 2 types of connectors: RJ-45 and BNC

  5. Other PC Devices and their Connectors • KEYBOARD-PS/2-style mini-DIN • MOUSE- used to be connected via a SERIAL port. • Serial ports are either 25 or 9 pin male DB. Serial ports send streams of data one bit at a time • Now the mouse in connected with a mini DIN connector through a PS/2 mouse port which is a special serial port

  6. Other PC Devices and their Connectors • MODEMS- translates analogue telephone signals into digital serial data. Can be internal or external. Both have built in serial ports. Use 2 RJ-11 connectors • PRINTERS- Use parallel ports, which are 25 pin female DB connectors. • JOYSTICK- 15 pin female DB

  7. Jumpers and DIP switches • The Primary tools of Hardware setup. • DIP SWITCHES- can be on or off, which is which? • JUMPERS- tiny pins, grouped together in two’s or three’s. “Shunts are put on them to create a circuit. • No shunt= Open or Off • With shunt= Shorted, Closed or On • Parked shunt=Not being used
