Describe 4 types

of memory

RAM stands for Random Access Memory and is a type of chip used in in primary storage memory. It is also temporary storage, holding software

instructions and short-term working memory for the processor. Most RAM is volatile that requires electrical power to hold data. The capacity of RAM is expressed in megabytes or gigabytes and personal computers typically

feature between 2 GB and 128GB of RAM. An area of the hard disk, called virtual memory, can be used if an application runs out of allocated RAM. Accessing data in memory can be more than 200, 000 times faster than accessing data on hard disk, Because of the mechanical motion of

the hard disk. The access time (speed) of memory contributes to the overall performance of the computer – in nanosecond.

EEPROM stands for Electrically Erasable

Programmable Read-Only Memory. It is

more permanent than RAM, and less

permanent than ROM. Requires no power to hold data. Hold their startup instructions

because it allows the computer easily update

its contents.

CMOS is an acronym for complementary metal oxide semiconductor. In short, CMOS defines the type of material from which the chip is

made. CMOS runs on about a millionth of an amp of electrical current. This efficiency allows it to store configuration data for a long time

(maybe years), powered only from either low-voltage dry cell or lithium batteries. Nonvolatile storage in contemporary computers is often

in EEPROM or flash memory (like the BIOS code itself), the remaining usage for the battery is then to keep the real-time clock (RTC) going.

The typical NVRAM capacity is 512 bytes, which is generally sufficient for all BIOS settings.

ROM is a type of memory circuitry that holds the

computer’s startup routine, this is a

permanent and non-volatile memory. The ROM BIOS tells the

computer how to access the hard disk, find the operating system, and load it into RAM.ROM

chips in printers contain data for FONTS

Jerry don’t have the software

The best way Tom should do is by

reopen the image, modify the image as long it is same as before, click the "file" option and choose "save as". It is up to the user to change the name but the "save as type" need to be change from jpeg to gif.
