The various PC connection methods are:
-Ports
-Personal Computer Connections
-Serial Connections
-Parallel Connections
-Universal Serial Bus (USB) Connections
-IEEE 1394 and FireWire Connections
-Small Computer Systems Interface (SCSI) Connections
-Parallel ATA (PATA) Connections
-Serial ATA (SATA) Connections
Let's see the details of connection
Port
A port is a hardware connection interface on a personal computer that enables devices to be connected to the computer. 
Personal Computer Connection
A personal computer connection is a means by which a personal computer component is attached to other components to provide computing capabilities.
Serial Connections
A serial connection is a personal computer connection that transfers data one bit at a time over a single wire. 
Parallel Connections
A parallel connection is a personal computer connection that transfers data eight bits at a time over eight wires and is typically used to connect a printer to a system unit. 
USB Connections
A USB connection is a personal computer connection that enables you to connect multiple peripherals to a single port with high performance and minimal device configuration. 
IEEE 1394 and FireWire Connections
A FireWire connection is a personal computer connection that provides a high-speed interface for peripheral devices that are designed to use the IEEE 1394 standard. 
Small Computer Systems Interface (SCSI) Connections
A SCSI connection is a personal computer connection that connects internal and external components to the system unit and provides for high-speed data transfer.
Parallel ATA (PATA) Connections
A PATA connection is a personal computer connection that provides a parallel data channel from a disk controller to the disk drives. 
Serial ATA (SATA) Connections
A SATA connection is a personal computer connection that
provides a serial data channel between the drive controller and the disk drives.
Summary
In this session, you learned that:
~The four primary components of a typical personal computer are system unit, display device, input devices, and external devices.
~The major components of the system unit are system board,CPU, memory, system bus, and storage devices.
~The various types of storage devices used in personal computers are FDD, HDD, optical drives, tape drives, and solid state storage devices.
~The various PC connection methods are ports, PC connections, serial connections, parallel connections, USB connections, IEEE 1394 and FireWire connections, SCSI connections, PATA connections, and SATA connections.
