Nt1110 Computer Memory
Random Access Memory – RAM. Where information is stored temporarily when a program is run. Information is automatically pulled into memory, we cannot control this. RAM is cleared automatically when the computer is shutdown or rebooted. RAM is volatile (non-permanent).
b. Read Only Memory – ROM. More permanent than RAM. Data stored in these chips is nonvolatile -- it is not lost when power is removed. Data stored in these chips is either unchangeable or requires a special operation to change. The BIOS is stored in the CMOS, readonly memory. c. Hard Drive – Where you store information permanently most frequently. This is also nonvolatile.
4. Motherboard – A circuit board that allows the CPU to interact with other parts of the computer. …show more content…
Most computers come with two PS/2 ports.
g. Ethernet Port – This port is used for networking and fast internet connections. Data moves through them at speeds of either 10 megabits or 100 megabits or 1 gigabit (1,000 megabits) depending on what speed the network card in the computer supports. Little monitor lights on these devices flicker when in use.
6. Power Supply – Gives your computer power by converting alternating current (AC) supplied by the wall connection to direct current (DC).
7. Expansion Cards – Used to add/improve functionality to the computer.
a. Sound Card – Used to input and output sound under program control.
Sound cards provide better sound quality than the built in sound control provided with most computers.
b. Graphics Card – Used to convert the logical representation of an image to a signal that can be used as input for a monitor.
c. Network Card – Used to provide a computer connection over a network. Transmit data at 10/100/1000 Mb/s.
8. CD ROM – A device used to read CD-ROMs. If capable of writing to the
CD-ROM, then they are usually referred to as a ‘burner’ or CD-RW.
9. DVD ROM – A device that is used to read DVDs/CDs. If capable of
