Master this for exam (29 cards)
Any physical device capable of storing information temporarily
Computer memory
Utilized integrated circuits and are use by operating systems, software, and hardware
Memory Devices
Keeps its contents even if the power is lost. Give example
Non-volatile, EPROM
Loses its contents when the computer or hardware device loses power. Give example.
Volatile Memory, RAM
Types of ROM
PROM, EPROM, EEPROM
Types of RAM
EDO RAM, SDRAM, DDR RAM, DDR2, DDR3, DDR4
What is SIMM and DIMM
Single inline memory module, Dual in line memory module
Makes up the typical computing device’s RAM, this data must be constantly refreshed with an electronic charge every few milliseconds to compensate for leaks from the capacitor
Dynamic Random Access Memory (DRAM)
Doesn’t need to be constantly refreshed, the transistor acts as a switch 1 and 0.
Static Random Access Memory (SDRAM)
What year was SDRAM first introduced?
1990
What year was DDR SDRAM developed?
2000
How many times did the DDR SDRAM evolved? And what are they?
3 times, DDR2, DDR3, DDR4
Other secondary storage devices are also known as…?
Disconnected or removable devices
This type of RAM is used in graphics and video cards
GDDR SDRAM (Graphics Double Data Rate)
The CPU access the memory through an…?
INPUT - OUTPUT
What is the latest generation of graphics memory?
GDDR6
It is called an external memory or ROM. Slower than the main memory
Secondary Memory
Referred to as disk space, disk storage, or storage capacity is the maximum amount of data a disk is capable of holding.
Disk Storage Capacity
Microprocessor accepts input, process it according to the instructions stored in the memory and later on produces output. What is this process called?
Data Processing Cycle
Referred to as a processor, central processor, or microprocessor.
Central Processing Unit (CPU)
A hard drive can be partitioned into sections that give the appearance of a new drive.
Partition Capacity
The CPU was first invented and developed at _____ with the help of _____ and others in the early _____. The first processor released was the ______.
Intel, Ted Hoff, 1970s, Intel 4004
This handles all instructions it receives from hardware and software.
CPU
What does ALU mean?
Arithmetic Logic Unit, performs mathematical, logical and decision operations
