1.2 Memory
- ROM
- Read only memory, ROM is non
volatile so when you turn off
your computer/device it'll save
everything in ROM
- ROM is the thing that keep you computer
running if you had no ROM your monitor
wont proccess any words because its there
to read only what its set to do
- It doesn't lose data when your device
is turned off
- Once data has been written onto a
ROM chip, it cannot be removed and
can only be read
- Read only memory
- It doesn't lose data when your device
is turned off
- Read only memory, ROM is non
volatile so when you turn off
your computer/device it'll save
everything in ROM
- Cache
- To store data locally in order to speed up subsequent
retrievals. Pronounced cash. See Web cache and
browser cache.
- GHz
- MHz
- The cpu is made of cache,
cores and clock speed
- GHz
- Reserved areas of memory in every computer
that are used to speed up instruction
execution, data retrieval and data updating.
- Cache memory, also called CPU memory, is random access
memory RAM that a computer microprocessor can access more
quickly than it can access regular RAM
- To store data locally in order to speed up subsequent
retrievals. Pronounced cash. See Web cache and
browser cache.
- RAM
- RAM (pronounced ramm) is an acronym
for random access memory
- a type of computer memory that can be
accessed randomly
- that is, any byte of memory can be accessed without touching
the preceding bytes.
- Random access memory (RAM) is a type of data storage used in
computers that is generally located on the motherboard.
- This type of memory is volatile and all information that
was stored in RAM is lost when the computer is turned
off
- This type of memory is volatile and all information that
was stored in RAM is lost when the computer is turned
off
- Random access memory (RAM) is a type of data storage used in
computers that is generally located on the motherboard.
- that is, any byte of memory can be accessed without touching
the preceding bytes.
- Random access memory
- a type of computer memory that can be
accessed randomly
- RAM (pronounced ramm) is an acronym
for random access memory
- Flash Memory
- a kind of memory that retains data in the
absence of a power supply
- for transfering data between a personal
computer PC and digital device.
- Flash memory is a non-volatile memory chip used for
storage
- Flash memory is a non-volatile memory chip used for
storage and for transfering data between a personal
computer
- Flash memory is a type of electrically erasable
programmable read-only memory
- Flash memory is a non-volatile memory chip used for
storage and for transfering data between a personal
computer
- Flash memory is a non-volatile memory chip used for
storage
- a kind of memory that retains data in the
absence of a power supply
- Solid State
- This is no moving parts and it used flash memory
- Because it has no moving parts its hard to hack
- solid states are faster than hard
disk because there is zero latency
- An all-electronic storage device that is an alternative to a hard disk
- solid states are faster than hard
disk because there is zero latency
- Because it has no moving parts its hard to hack
- This is no moving parts and it used flash memory
- Virtual
memory
- Virtual memory is needed to
let more memory in then there
is available in the system
- it is temporary memory
- it is located on the
hard drive
- Virtual memory is an area
of secondary storage that is
used like RAM
- rapidly exchanging data in memory for data on disk, to
the exclusion of most application-level processing
- rapidly exchanging data in memory for data on disk, to
the exclusion of most application-level processing
- Disk thrashing: In computer science, thrashing occurs when a
computer's virtual memory subsystem is in a constant state
of paging
- Virtual memory is an area
of secondary storage that is
used like RAM
- When the hard drive is
full you can no-longer
do things such as copy
and paste
- Virtual memory is needed to
let more memory in then there
is available in the system
- Registers
- A processor register CPU register is one of
a small set of data holding places that are
part of the computer processor
- A register may hold an instruction, a
storage address, or any kind of data
- A register may hold an instruction, a
storage address, or any kind of data
- The storage time of internal registers is
extremely temporary, as they often hold
data for less than a millisecond
- A processor register CPU register is one of
a small set of data holding places that are
part of the computer processor
