The USB was created in 1995 by several companies to provide a universal connection standard for computer devices. It was developed to address the problem of every new device requiring a unique serial port. The USB allows for cost effective and power efficient connections of devices through a small, durable port. While small USB drives can be easily misplaced, the USB standard provides versatility in connecting many types of devices, from keyboards to cameras. The USB standard has evolved from its initial 12 Mbps speed to today's 480 Mbps USB 2.0, with 5 Gbps USB 3.0 upcoming. Future developments may include wireless USB connections.

USB PD Introduction
USB PD (Universal Serial Bus Power Delivery) is a specification that enables flexible power delivery and data transfer over a single USB cable. It allows devices to negotiate the power they require through communication with the power source. This increases power levels above existing USB standards, up to 100W. It also allows power to flow in either direction and devices to draw only the power needed for a given application in order to optimize power management across multiple devices.
Optical disc drive
An optical disc drive uses lasers to read and write data to optical discs such as CDs, DVDs, and Blu-ray discs. It contains lasers and lenses to guide the laser beam to the disc, and photodiodes to detect light reflections from the disc. ODDs can be internal, connected via IDE or SATA interfaces, or external, connected via USB or FireWire. Potential issues include the drive not being recognized, improper cabling, or laser/mechanical faults. Troubleshooting involves checking for physical damage, cleaning the lenses, ensuring proper BIOS detection, and replacing faulty components.
Identification of parts of motherboard
The CPU executes instructions to run programs and performs basic logic, arithmetic, and input/output operations. A motherboard is the main circuit board that contains the CPU and connections for components like RAM, graphics cards, hard drives, and ports. RAM is a type of memory that can be quickly written and read from, and is used to store active programs and data.
Hard Disk
This document discusses the components and operation of hard disk drives. It describes how hard disks store data using longitudinal or perpendicular magnetic recording. The key components of a hard disk drive are platters, read/write heads, cylinders, and a spindle. Platters are coated disks that store data magnetically. Read/write heads barely touch the platter surface to read and write data. Cylinders refer to vertical sections of tracks that pass through all platters. The spindle holds the platters and rotates them at high speeds during operation.
Partitioning a Hard Drive
Partitioning a hard drive involves creating, deleting, and formatting partitions to organize and manage the drive's storage space. It is commonly done when purchasing a new hard drive. Using disk management built into Windows, you can create partitions by selecting "New Simple Volume" on unallocated space. You can delete partitions by right clicking the unwanted partition and selecting "Delete Volume." Formatting a partition allows changing its file system or wiping data; right click the partition and select "Format" to begin this process. Partitioning provides benefits like independent storage areas that won't break other partitions if one fails, easier data organization, and the ability to encrypt partitions for security.

A computer is a machine that performs mathematical and logical calculations using electricity and electronics. Early computers were enormous machines that filled entire rooms and used vacuum tubes. Advances like integrated circuits, transistors, and microchips made computers smaller and more accessible. Now, computers contain components like CPUs, memory, storage drives, and peripherals inside their cases. Hardware is the physical components while software is abstract computer code.
Basic computer fundamentals (1)
This document provides an overview of basic computer fundamentals, including definitions of hardware and software. It describes how a computer works at a fundamental level and defines key components. Specifically, it defines a computer as a programmable machine that can execute a list of instructions. It describes how modern computers are electronic and digital, and can be understood through their hardware and software. It provides examples of hardware components like chips and keyboards, and describes software as programs without physical substance. It also defines other important concepts like binary, bits, bytes, and how computers use random access technology to retrieve data.
About USB
USB (Universal Serial Bus) is a specification that allows for communication between devices and a host controller, usually a personal computer. It was designed to replace many serial and parallel ports and can connect devices like mice, keyboards, cameras, printers, and external storage. The USB specifications have evolved over time, with USB 1.0 introduced in 1996 at 1.5 Mbps, USB 2.0 in 2000 at 12 Mbps, and USB 3.0 in 2008 at 480 Mbps. USB allows for branching connections between devices using a tiered-star topology.
Computer Fundamental
The document provides information about computers and their components. It defines what a computer is and describes some key parts like the CPU, memory, storage devices, and input/output components. It also discusses the history of computers and important figures like Charles Babbage. Generations of computers are outlined and examples of components like processors, monitors, and printers are explained. Storage capacity units and memory types are also defined.

- 1. Universal Serial Bus(USB) By Aaron Specht
- 2. History When: In 1995-96 Compaq, Digital Equipment Corporation (DEC), IBM, Intel, Microsoft and NEC, joined later by Hewlett-Packard, Lucent and, Philips got together and designed the USB
- 3. History Why? The USB was created out of a need for universal communication between devices. The problem with that was that computer designers were literally running out of room Before the USB every new computer device needed a different serial port.
- 4. Advantages USB Flash Drive Cost effective Power efficient Universal design One fits all Resistant to scratches and Dust Convenience Size
- 5. Disadvantages Size Being to small leaves some devices to be easily misplaced It breaks its gone Compared to some CD’s that can be repaired once scratched to retrieve data USB’s once they fail they fail.
- 6. How it Works. Enumeration the computer would decided which kind of data the device uses Interrupt - low data transfer - keyboard or mouse Bulk - large amounts of data - printer or external hard drive Isochronous - streamed data - microphones or speakers
- 7. Encoding the process of recoding or modifying information into a desired format or pattern is when the two devices communicate and configure to which form of data transmission should be used
- 8. Transmission Convey information from the device to another location. Can be as simple as typing a few keys on the keyboard or transferring large amounts of data like pictures, music and the like
- 9. Receiving Recognizes and accepts information from transition and collects the inputs and readies them for storage This would be where the typed keys would be displayed onto the screen or stored in a word document.
- 10. Versatility USB can be incorporated into just about anything. Toys Camera’s Phones Speakers
- 11. Versatility Instruments Microphones Lights Cooling fans
- 12. Evolution USB 1.0 – 1.1 Maximum transfer rate of 12 mbps First appeared on market in 1995 and 1998
