SRAM also known as Cache is used to store the most used data.

It provides faster access to data than retrieving it from the slower DRAM,

The three main types of cache memory are L1, L2 and L3.

L1 is cache memory integrated into the CPU. L2 is cache memory which is also integrated into the CPU. L3 is cache memory is used on only some high end workstations.

Dynamic Temporary Storage often refers to computer components and recording media that retains data.

Dynamic Temporary Storage is the core function of computers in memory.

There are many different types of memory like:

-SDRAM-GB PATA-SDLT

EEPROM (Electrically Erasable Programmable Read-Only Memory) is a type of memory that can retain the stored information even when not powered on.

EEPROM has helped make Flash Memory for the computer which basically does the same job to EEPROM.

The data must be saved before the computer is powered off.

Flash Memory is also memory that can retain stored data even when the computer is not powered on, which can be electrically erased and reprogrammed.

It was developed by EEPROM (Electrically Erasable Programmable Read-Only Memory).

The data must be erased in quite big blocks before they can be rewritten with new data.

USB Memory Sticks and Memory Cards are types of Flash Memory.

Adapter Cards are used to give a lot more capability of the computer by expanding and customizing it.

There are lots of different kinds of Adapter Cards. There are Adapter Cards like Network Interface Cards (NIC), Wireless NIC, Sound Adapter, Video Adapter, Capture Card, TV Tuner, Modem Adapter, SCSI Adapter and RAID Adapter.

Expansion Slots lets you plug in Adapter Cards on the Motherboard. The type of Adapter Card must match with the expansion slot.

There are lots of different kinds of Expansion Slots like PCI, AGP, PCle, ISA, EISA and MCA.

Storage Drives read or write information to optical storage media. It can store permanent data or to retrieve information from a media disk.

SATA refers to the serial versions of the ATA drive controller. It uses a 7-pin data connector.

PATA refers to the parallel version of the ATA drive controller interface.

SCSI can connect both internal and external drives. It uses 50-pin, 68-pin and 80-pin connectors.

Partitioning and Formatting is when you set up a new, empty hard disk so that you can put it into an Operating System.

An Input Device is used to put data into a computer by plugging it into the computer.

Input Devices are devices like:

Mouse Keyboard Camera Biometric Authentication Device Touch Screen Scanner

An Output Device is used to take information from a computer by using special equipment.

Output Devices are devices like:

Monitors Projectors Printers Scanners Fax Machines Speakers Headphones
