The document discusses several key components of internet and computer systems. The CPU controls the operating system and has processors ranging from 2.1-3.1 GHz depending on whether it's a laptop or normal computer. Memory comes in various types like ROM, RAM, SRAM, and DRAM that allow storage and retrieval of data. Adapter cards like PCI and PCIe connect hardware to the motherboard. Storage devices include hard drives connected via PATA, SATA, or SCSI interfaces, and solid state drives. Input devices provide input to computers while output devices like monitors provide output.

2. CPU
A CPU (Central Processing Unit) is like the brain
of the computer. It controls every operating
system.
It has 64 bit processor.
For a normal computer its 3.1 GHz and for
laptops its 2.1 GHz.
The mother stores the memory on it.

3. Memory
• ROM: Read only memory it is a
software component that hold
hardware components.
• RAM: random access memory it allow
you to open more than one
applications at the same time.
• sRAM: statics random access memory
is if you store some thing it will stay
there until it has been removed.
• dRAM: dynamic random access
memory is if you store something is
only keeps it for a limited time unless
it a refreshed.
• EPROM: erasable program read only
memory this allows you to keep the
memory even if the powers been
turned off.
• Flash memory permanent storage: is a
storage that can be re written or re
programed.

4. Adapter cards
• PCI: peripheral component
interconnect this can connect
hardware to the mother board.
• PCIe: peripheral components
interconnect express is the
upgraded and faster version of
PCI and AGP.
• On board and pcmica: is a
portable card for expanding your
laptop witch is a hot plugging
devise.
• Card BUS: is a version of pcmica
that is used for laptops and Wi-
Fi.

5. BUS types
• Buses are something that moves data around
the mother board. There is three types of bus
control bus, address bus and data bus. Thiess
busses are in a system bus.

6. Storage devises
• PATA: is a interface component for storage devises.
• SATA: is a newer faster version of PATA and it allows
hot swapping.
• SCSI: it’s a small computer system interface. Its for
connection peripherals and allows 8 and 16 bit devises
on a single bus.
• Solid state: is a new hard drive that uses integrated
circuits for memory.
• Partitioning: splitting up a hard drive in to multiple
segments.
• Formatting: setting the hard drive for a set file format
like FAT32 and NTFS.

7. Input and output devices
• Input devices are devices that feeds
information in to the computer. Things like
keyboards, mice, microphones and touchpads.
• Outputs are devices that feed information out
from the computer. Things like monitors,
earphones, speakers and printer.
