RAM—Random Access Memory.
This is the computers short term memory, the computer uses ram to store
information from programs that is needed while the program is running. This
type of memory is very volatile and is wiped out when the computer is shut off.
ROM—Read Only Memory. As the
name suggest this memory can only be read from and not written to and is
usually non-volatile.
Cache—this is memory
set-a-side by a program like Internet Explorer to store information that is
referenced for later use. It aids in speeding up the loading of web pages.
Swap File—similar to cache,
except that it is used by windows when there isn’t enough RAM to run a program.
Bit—the smallest portion of
data measurement.
Byte—8 bits.
KB—short for kilobyte, 1
thousand bytes. The actual number of bytes is 1024 this is because bytes are measured
in the octal number system and then translated by the computer back into the
decimal number system.
MB—short for megabyte, 1
million bytes.
GB—short for gigabyte, 1
billion bytes.
TB—short for terabyte, 1
trillion bytes.
Decimal number system—this is
the number system that we humans use to count. Also known as base 10 because
there are 10 digits as the base of the system 0 thru 9, 0 is the first number
and 9 is the tenth number.
Octal number system—one of
three number systems used in computing. Also known as base 8, because there are
8 digits as the base of the system, 0 thru 7 with zero as the first digit and 7
as the last.
Binary number system—one of
three number systems used in computing. Also known as base 2, because there are
2 digits in the system 0 and 1, this is also the language of all computers.
Hexadecimal number system—one
of three number systems used in computing. Also know as base 16, because there
are 16 digits as the base of the system, the first 10 are 0 thru 9, while the
last 6 are the letters A thru F.
Machine language—the binary
number system is the language of all computers. All calculations are done by
the computer using binary numbers.
Boolean logic—sometimes
called Boolean algebra, uses the binary number system to perform operations.
Dip switches—an obsolete
method of configuring hardware using small binary switches, they are either
turned off (set to 0) or turned on (set to 1). Old style printers usually have
them.
Dot matrix printer—a now
obsolete style of printer that uses tiny dots to print text or graphics.
DPI—Dots Per Inch. The number
of dots per inch a dot matrix printer will print, the higher the number the
better.
Daisy wheel printer—a text only
printer which gets its name from the wheel that contains all the letters,
numbers and punctuation characters needed to print text.
Ink jet printer—a method of
printing by spraying ink with little jets. This is a common style of printer it
is cheep and fairly efficient, with high quality.
Bubble jet printer—this is
similar to ink jet printer made by the Canon Corporation. It has the same
quality as ink jet and affordability.
Laser printer—a fast high
quality printer that uses a laser to burn the images on to the paper, it is
however, very expensive.
ASCII—American Standard Code
for Information Interchange; this has been the standard for a long time but is
slowly dying if not dead already. The code consists of 256 characters each
represented by a number 0 thru 255. The code contains all the punctuation
marks, letters of the alphabet both upper- and lower-case, and numbers of the
American writing system, plus a bunch of other characters most of which are not
printable.
Font—this is the name given
to the style in which text is appears on the screen, not to be confused with
Italics or underlined as these are formats for text. An example of a font is
the text you see on this page it is known as Arial. This is Bookman Old
Style, and this
is Courier New.
Boot—to start your computers
operating system.
BIOS—Basic Input Output
System, this is ROM memory which helps the computer process all input and
output. It controls all of the computers hardware including, CPU, RAM, IRQ’s,
Hard drives, etc. It also tells the computer where to look for the operating
system boot files. The BIOS is kept alive via a battery that is located on the
motherboard.
CMOS--Complementary Metal Oxide Semiconductor sometimes referred to as the BIOS.
They are used interchangeably; however, CMOS, pronounce sea moss, is actually
the chip in which the BIOS is stored.
Motherboard—also
call the main board, this is the main circuit board that all the computers
hardware plugs into, including the BIOS.
CPU—Central
Processing Unit this is the number cruncher, it does all the calculations in
binary.
Drivers—software
used to tell the operating system how to control the specific hardware.
Hardware—these
are the physical components of a computer, examples include the CPU, Modem,
CD-ROM, etc.
Software—these
are programs that perform a useful function like the operating system, word
process, or drivers.
Programming
language—software used to develop programs.
RAD—Rapid
Application Development, a style of program development using a programming
language.
GUI—Graphical
User Interface, interfacing with a computer using graphics rather than text,
makes for easier usage without the need for typing complex text commands.
OS—Operating
System, software that manages all the computers resources, translates
instructions to machine language, etc.
IRQ—Interrupt
Request a system resource which allows for the interruption of a task being
performed so that another task can be performed.
Blue
screen of death—this is the blue screen that appears whenever windows is having
problems, throws a fit, crashes, etc. a very annoying screen if you ask me.
Java—a
programming language created by Sun Microsystems.
HTML—Hyper
Text Markup Language a programming language used in creating web pages.
WYSIWYG—What
You See Is What You Get as style of web page design that uses GUI interfacing
rather than HTML coding.
