Components

Question 1

CPU(1)

Answer 1

1 - CPU uses transition books or instruction set to translate and perform function data on our computer.
2 - CPU and motherboard type must match.
3 - there are types of CPU processor, like Intel Core i7 and Snapdragon 810.

Question 2

CPU(2)

Answer 2

4 -There is the socket that CPU must fit; Land Grid Array ( pins stick out) and Pin Grid Array ( have contact points that look like dots).
5 - Computers have either 32 or 64 bit ( how much data it can efficiently handle
6 - Heat sink takes heat from CPU and dissipates it through a fan or another medium.

Question 3

RAM

Answer 3

1 - RAM loses its short term memory when computer is turned off.
2 - There are different types of RAM:
- DRAM (dynamic random access memory) (1s and 0s) stores bits in a microscopic capacitor. They are semiconductors put into chips that are on the RAM and stores our data.
- DIMM(dual line memory module) have different size of pins on them
- SDRAM or Synchronous DRAM is synchronized into clock speed, allowing faster process of data.
- double data rate DRAM is faster, less power and takes up less space (DDR4 is the latest iteration).

Question 4

Motherboard

Answer 4

1 - Motherboards have few key characteristics.
2 - A Chipset is a key aspect that allows us to manage data between CPU, RAM and peripherals (Northbridge handles RAM and video cards and Southbridge handles input/output controllers like hard drives and usb devices.
3 - peripheral is external devices we connect to computer like mouse.
4 -Expansion slots, which very between small/weak and large/very powerful. there are types like ATX.

Question 5

Storage

Answer 5

1 - there are two types of basic hard drive today.
2 - HDD (hard disk drive) which use spinning platter and mechanical arm to read and write info. RPM (revolution per minute) faster the better.
3 - SSD has no moving parts and info is stored on microchips and data travels faster. Slimmer as well.
4 - HDD break easier but are more accessible; SSD are more durable but are more expensive.
5 - Among the interface that hard drive uses are ATA (SATA or serial, are most popular) uses one cable for data transfer. Hot swappable ( can keep machine on when plugging ATA).
6 - New iteration is NVM express (NVME) and can be inserted into an expansion slot.

Question 6

Power Supplies

Answer 6

1 - DC is electricity that flows in one direction and AC changes direction. Computer has DC
2 - Power supply converts AC from the wall to DC.
3 - Amps pull electricity as needed and voltage push everything.
4 - watts is the amount of volts and amps that a device needs. err on the side on more.

Question 7

Mobile Devices

Answer 7

1 - mobile devices, like computer, have CPU, RAM, storage, power systems and peripherals.
2 - They have a system on a chip( SoC) which uses less power than the separated ones.

Question 8

Batteries and Charging Systems

Answer 8

1 - Rechargeable devices might have an external charger for a removable batteries, or might have a cradle stand or wireless charger.
2 - Rechargeable batteries have limited lifespan, which is measured by one cycle of charging and docking off.
3 - rechargeable batteries can be damaged by hot or cold temperatures environments

Question 9

Peripherals

Answer 9

1 - USB (Universal Serial Bus) has USB 2.0 (480Mb/s), USB 3.0 (5 Gb/s) and USB 3.1 (10 Gb/s).
2 - Popular type is USB type C, which to replace older versions for display and data transfer
3 - Display peripherals include DVI (output videos only) and HDMI (both video and audio).
