System Board:The system board is the personal computer component that acts as the backbone for the entire computer system. Central Processing Unit (CPU):The central processing unit (CPU), sometimes called microprocessor or just processor, is the real brains of the computer and is where most of the calculations take place. Memory:Memory is the personal computer component that comprises the electronic storage areas in the computer. It can be considered either volatile or non-volatile. System Bus :The system bus is the main communication path between the CPU and memory. Storage devices :A storage device is a system unit component, such as a hard drive, that enables users to save data for reuse at a later time, even after the personal computer is shut down and restarted. Power supplyis an internal computer component that converts AC power from an electrical outlet to the DC power needed by system components. Adapter cardis a printed circuit board that you install into a slot on the computer’s system board to expand the functionality of the computer. Riser cardis a board that plugs in to the system board and provides additional slots for adapter cards..

The main memory stores data and instructions. Main memories are usually built from dynamic IC’s known as dynamic RAMs. These semiconductor ICs can also implement static memories referred to as static RAMs (SRAMs). SRAMs are faster but cost per bit is higher. These are oten used to build caches. continue to full answer….View full post

The various types of storage devices used in personal computers are:
- Floppy Disk Drives (FDD): is a personal computer storage device that reads data from, and writes data to, removable disks made of flexible Mylar plastic covered with a magnetic coating and enclosed in a stiff, protective, plastic case.
- Hard Disk Drives (HDD) :is a personal computer storage device that uses fixed media, which means that the disk is built into the drive and the drives are not removed from the computer unless you are performing an upgrade or a repair.
- Optical Drives: is a personal computer storage device that stores data optically, rather than magnetically.
- Tape Drives: is a personal computer storage device that stores data magnetically on a removable tape that is enclosed in a tape cartridge.
- Solid State Storage devices: is a personal computer storage device that stores data in special types of memory instead of on disks or tape.

The various PC connection methods are:
- Ports : is a hardware connection interface on a personal computer that enables devices to be connected to the computer.
- Personal Computer Connections : is a means by which a personal computer component is attached to other components to provide computing capabilities.
- Serial Connections : Serial connection is a personal computer connection that transfers data one bit at a time over a single wire.
- Parallel Connections : 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.
- Universal Serial Bus (USB) Connections : 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.
- Infrared connection : Infrared connections require no additional wiring, and both devices come with IrDA ports as standard. However, infrared connections require line-of-sight to operate reliably, and even then performance is not acceptable for debugging. However, IrDA can be useful as a last resort technique to copy files to devices.
- Bluetooth : Many devices feature Bluetooth wireless networking. Once paired, the smart device can connect over ActiveSync as long as it is within range of the desktop computer. Because Bluetooth is not as fast as 802.11b/g wireless, avoid using it for debugging.
- Wireless 802.11b/g network : Wireless networking is as fast as a wired Ethernet network connection.
- IEEE 1394 and FireWire Connections : 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.

Cascading Style Sheet:
CSS is the language for describing the presentation of Web pages, including colors, layout, and fonts. It allows to adapt the presentation to different types of devices, such as large screens, small screens, or printers. CSS is independent of HTML and can be used with any XML-based markup language. The separation of HTML from CSS makes it easier to maintain sites, share style sheets across pages, and tailor pages to different environments. This is referred to as the separation of structure (or: content) from presentation.
