This document provides an introduction to the main internal and external parts of a computer. It discusses the monitor, mouse, keyboard, chassis, motherboard, power supply, hard drive, floppy drive, CD/DVD drive, RAM, ROM, microprocessor, expansion cards, ports, slots, and chipset. It provides details on the purpose and basic functioning of each part.
Memory devices can be classified in several ways:
1. By location as registers, main memory, and secondary memory. Registers are inside the CPU while main memory is external but faster than secondary memory like hard disks.
2. By access as sequential (location must be accessed in order) vs random access memory (RAM) which allows random access.
3. As static (maintains data without refresh) vs dynamic RAM which must be periodically refreshed.
4. As volatile (loses data on power off) vs non-volatile like ROM and magnetic storage.
Read-only memory (ROM) is non-volatile and only allows reading. It is used to permanently store information. Various RO
Computer hardware includes various components that perform different functions like input, processing, output, and storage.

The document defines the key components of a computer system including hardware, software, and input/output/storage devices. It describes hardware as the physical parts like peripherals for input/output and storage. Software are sets of instructions that control the computer's operation. Input devices allow data to enter the system, storage devices save data long-term, and output devices present data to the user. The purpose of each is also outlined.
The document defines and provides brief explanations of several key components of computer hardware that are important for game platforms. It discusses the central processing unit (CPU), graphics processing unit (GPU), random access memory (RAM), storage mediums, interface devices, connectivity, displays, sound cards, and power supplies. Each component is defined with a short description of its function and importance to operating a computer system and playing games.
Primary storage, also called main memory or immediate access store (IMAS), consists of random access memory (RAM), read only memory (ROM), and cache. RAM holds data and instructions temporarily during processing and also holds the results, while ROM stores fixed system-level programs like the BIOS needed for starting up the computer. Cache provides very fast temporary memory the processor can access more quickly than RAM.
The document discusses computer memory units. It describes three types of memory: internal processor memory, primary memory (RAM and ROM), and secondary memory (magnetic tapes, disks, and optical disks). Primary memory handles data, with RAM being volatile and ROM being non-volatile. Secondary memory stores output and installed software. The document also defines common units for measuring computer memory capacity, such as bytes, kilobytes, megabytes, and terabytes.
Desktop computers are intended for regular use at a single location due to their size and power needs. A typical desktop computer consists of a monitor, keyboard, mouse, hard disk for storage, CD-ROM or floppy disk for transferring data, RAM for temporary memory storage, ROM for permanent storage, and a processor as the central component. Additional devices like optical mark readers can be used as specialized input devices to read marks on paper into the computer.

The south bridge connects slower devices like the PCI bus, IDE interfaces, and USB ports. It also controls the floppy disk drive and BIOS chip. Modern motherboards use the north and south bridge architecture to connect the various internal and external components.
The document discusses the history and components of computers. It describes how early computers were developed to perform calculations but are now used for a variety of purposes. The main components of a computer are the central processing unit, memory, storage devices, input devices, output devices, and buses that connect them. The CPU fetches and executes instructions while the memory stores active programs and data. Common internal components are the motherboard, processor, RAM, and hard drive, while external components include keyboards, mice, displays, and optical drives.
Storage devices in computer systems can be classified into three categories: primary storage (RAM), secondary storage (hard disk drives), and tertiary storage (tape drives). RAM is used for short-term storage and access by the CPU, while hard disks provide permanent secondary storage. Tertiary storage devices like tape drives are used for offline backup and archiving. The document then discusses the evolution of storage technologies over time, from early memory technologies like Williams tubes and drum memory, to floppy disks, hard disks, flash memory, and modern cloud storage solutions. It also explains key concepts like how data is represented digitally and stored on physical storage media.
The CPU controls all tasks inside the computer from basic to complex. RAM is temporary storage for active programs and data, flash memory can be deleted and reprogrammed in blocks, and ROM permanently stores data that can only be read. Adapter cards allow communication between computers and peripheral devices. The network topology determines available functions and resilience to failures. Storage devices like hard drives store and read information for the operating system, apps, and user files. Partitioning divides hard disks to create groups for multiple operating systems.
