Basic computer parts and application

1. USB: THE BASICS USB (Universal Serial Bus) It is a protocol* and hardware** standard for digital communications. Its primary aim is to standardized communication and power sources for computer peripherals.*** It combines data and power supply. Protocol - is  a standardized set of rules for formatting and processing data . Computer hardware –is any of the physical components of an analog or digital computer . Peripheral device - is  an external device that connects to a computer  to expand its capabilities.

3. COMMON USB COLOR Orange/Yellow USB Ports   are mostly on Smartphone Fast or Supercharge Chargers and indicates USB PD(Power Delivery) which is a compliant specification for fast / supercharge / adaptive charge smartphone charging rates. Red USB Connectors allows for speeds up to 20 Gbps , nearly 4 times faster than standard USB 3.0 speed of up to 5 Gbps.

5. TYPES OF UNIVERSAL SERIAL BUS (USB)

6. USB TYPE A Application: To couple peripherals (mouse, keyboard, gaming controller) to a host (computer, charging hub).

7. USB TYPE A (1.0-2.0) TERMINALS CABLE SHIELDING Protection against external disturbances (noise with high EMI or Electromagnetic Interference like lightning, solar storms, solar flares) which could be induced in the cables that may cause problems in surrounding IC’s and systems. Generally made up of Foil or copper braided shield.

8. USB TYPE A (3.0) TERMINALS

9. USB TYPE B Application: For printers and scanners for stable data transfer. For musical equipment like synthesizers (generate audio signal like keyboard), mixers, MIDI controllers (Musical Instrument Digital Interface).

10. USB TYPE B (2.0) TERMINALS

11. USB TYPE B (3.0) TERMINALS

12. USB TYPE MINI (A, B, AB) Application: Early generations of cell phone ports, mp3 players, cameras, chargers, microphones.

13. USB TYPE MINI A,B, AB (2.0 below) TERMINALS ID PIN - used to detect the USB connection and enable the USB serial port interface , OTG.

14. USB TYPE MICRO A Application: For powering and charging small devices (cell phones). For transmitting data. For external hard drives. 10 9 8 7 6 5 4 3 2 1 PINOUT MICRO A 3.0

15. USB TYPE MICRO B Application: For powering and charging small devices (cell phones). For transmitting data. For external hard drives. PINOUT MICRO B 3.0

16. USB TYPE C Application: Provide and receive power to/from a device. Carry audio, video and other data to connect to monitor and external drives. *Chanel Configuration (CC) - for cable detection, orientation & current carrying capability. * Sideband Use (SBU) – for audio adapter, accessory mode, & alternate mode (usb4, display port, HDMI)

17. *Volatile Memory , which means that the information temporarily stored in the module is erased when you restart or shut down your computer. *SRAM (Static Random Access Memory)- used for cache and internal registers of a CPU. *DRAM (Dynamic Random Access Memory) – used for main memory applications. *SDRAM (Synchronous DRAM) – laptop *RDRAM (Rambus DRAM) – for video games in 1990’s. *DDR (Double Data Rate)- for pc.

18. PC SECONDARY STORAGE It is the device internal memory for data storage.

19. TYPES OF PC SECONDARY STORAGE

20. POPULAR BRANDS OF PC SECONDARY STORAGE

21. 1. HARD DISK DRIVE (HDD) It is also called “platter” drives. It consists of spinning disks, coated with a thin magnetic film, onto which data is written and read from. Used until 2000’s. Upto 32GB but commonly at 500GB, 1TB, 2TB. Ranging 30-150 MB/s. 1TB ≈ P2000 - P4,000 Pros Lower cost per GB than SSDs Available in high capacities Cons Physically larger than SSDs Moving parts vulnerable to damage Require cabling for data and power Require more power than SSDs. Lifespan of 3-5 years.

22. 1. SATA ( Serial Advanced Technology Attachment)- more affordable, commonly found and offers good performance for common applications. HDD INTERFACE/PORTS * Parallel ATA ( Parallel Advanced Technology Attachment  or PATA) is a legacy standard for connecting internal floppy disks, hard disk drives (HDDs) and optical disk drives to older computer systems.

25. 2. SOLID STATE DRIVE (SSD) It is a semiconductor-based storage device, which typically uses *NAND flash memory to save persistent data. Pros Use semiconductor chips to store data and have no moving parts. Faster, durable, more compact than HDD. More efficient than HDD (use less power) and run cooler. Average lifespan of 5 to 10 or 15 years. Higher storage capability. Cons Pricey. *NAND flash memory is a type of non-volatile storage technology that does not require power to retain data.

26. 2.5 SATA SSD 4.9”x3.1”x0.5” up to 5.2 GB/s 1 TB = P3000 - P6000 SSD INTERFACE/PORTS

27. 2. NVME (Nonvolatile Memory Express) up to 7 GB/s 1TB = P7000 SSD INTERFACE/PORTS

29. TYPES OF SSD 2.1) 2.5 SSD 4.9”x3.1”x0.5” (5-6 G B/s) 2.2) M.2 SSD (up to 20 GB/s)

30. TYPES OF SSD 2.3) m SATA SSD (3-5.5 GB/s up to 6 GB/s) 1 TB = P3000 – P9000

31. 2.4) U. 2 SSD @2.5 ssd size 4.9”x3.1”x0.5” Around 6.5 GB/s 1.92 TB = P11000 TYPES OF SSD Has higher operating temperatures and is more favorable for transferring heat than the M.2 form factor. For high-end workstations, servers & enterprise applications.

32. RAM (RANDOM ACCESS MEMORY) *Volatile Memory , which means that the information temporarily stored in the module is erased when you restart or shut down your computer. It is a temporary memory bank where your computer stores data it needs to retrieve quickly. Use for l oading apps (open/close/process), browsing websites, and editing documents, videos/photos.
