Hardware inside a PC
Fichas del conjunto (6)
- 1MOTHERBOARD - Connects crucial parts of the computer together SOME FEATURES INCLUDE: - Processor sockets that house the CPU and make electrical interface contact with it - DDR(X) memory slots that speed up chips without increasing clock speedBIOS
- Stands for Basic Input-Output System
- Contains all code needed to control hardware outside the PC - 2CPU - Stands for Central Processing Unit - Carries out instructions using "Fetch Execute" cycle - Speed of CPU measured in Megahertz (MHz) - One CPU core carries out one task at a time (why most CPUs have more cores) - Fan near CPU used for active cooling, so CPU cannot overheat"FETCH EXECUTE" CYCLE
- Three stages: "Fetch", "Decode" and "Execute"
- "Fetch" - CPU receives instructions
- "Decode" - CPU understands what needs to happen to carry out instruction
- "Execute" - CPU carries out instruction - 3POWER SUPPLY - Main electrical source for PC - Supplies power for the computerPORTS
- Connect input and output devices to the computer
DIFFERENT TYPES OF PORTS
- VGA port used for the connection of monitor
-HDMI port used for connection of television box or peripheral devices
- USB ports used for connecting pen drives into device
-RJ-45 port used for Ethernet
S-Video port used for video input - 4ETHERNET VS WIRELESS - Ethernet cables reach faster speeds and less interruptions -Wireless connections are much more convenient and take less time to set upRAM VS ROM
- RAM = Random Access Memory
- Place to hold inputted data
- ROM = Read-Only Memory
- Used for information that can only be read
- Example of ROM: EEPROM - 5HARD DRIVE - This is a type of long term storage device that stores dataVIDEO/SOUND/NETWORK CARDS
- Video cards generate output images to display
-Sound cards convert digital data to analogue sound waves so we can hear the sound
- Network cards connect electric circuitry required to communicate - 6OPTICAL DRIVE - Uses laser light to read data tf
