This rule of thumb describes the pace at which CPUs improve. This rule predicts that the number of transistors inside a CPU will increase so fast that CPU capacity will double every 18 months.
Moore's Law
Helps determine how fast it can process data.
The number of transistors on a CPU chip
the most common form of memory -found on personal computers—increases about 60 percent every year.
Dynamic random access memory
(DRAM)
Subsystems included in a system evaluation
• CPU subsystem,
• memory subsystem (the computer’s random access memory, or RAM),
• storage subsystem (hard drive and other drives),
• video subsystem (video card and monitor),
• audio subsystem (sound card and speakers), and
• computer ports.
Advantages of a Notebook
- portable
- take up less physical space
- easy to ship/ transport if system needs repair
Advantages of Desktops
- best value: more speed, memory, storage capacity for lower price
- more difficult to steal, less susceptible to damage from dropping/mishandling
- easier to expand &upgrade
It coordinates the activities of all the other computer components.
Control unit
Responsible for performing all arithmetic calculations & makes logic and comparison decisions
Arithmetic Logic Unit (ALU)
Series of steps that the CPU goes through to perform a program instruction
Machine cycle
The steady and constant speed of the machine cycle is known as:
Clock speed
CPU, of current systems, are measured in units of :
Gigahertz

(older systems: megahertz)
It connects the processor (CPU) in computer to the system memory
Front side bus (FSB)

(FSB like a highway on which data travels btwn CPU and RAM. Faster the FSB, the faster the data can get to the processor)
Form of random access memory that is more accessible and faster than regular RAM
Cache memory
Block of memory built onto the CPU chip for storage of data or commands that have just been used
LEVEL 1 Cache
Block of memory located on CPU chip but slightly farther away from CPU, or on a separate chip next to CPU
LEVEL 2 Cache
Which block of memory has more storage area?
a. level 1
b. level 2
B
Path in which Intel CPU's can work in parallel, processing two separate programs at the same time instead of switching back and forth between them
DUAL path processors for data
(dual core processors)
Instead of Task Manager, Mac OS X has a similar utility known as:
Activity Monitor
Enables you to migrate files and settings from windows xp to windows vista via a network connection by using flash drive or external hard drive, or optical media
Easy transfer companion(from windows vista)
The small circuit boards that hold a series of RAM chips & fit into special slots on the motherboard
memory modules (or memory cards)
Rather than System properties, Mac has :
About This Mac (from the Apple menu)
the absolute minimum amount of RAm that your computer can run on:
kernel memory ( because of additional applications, you will need more than the minimum of course)
Term used to say that the system is limited in how fast it can send data to CPU because there's not enough memory
Memory bound
When the OS is using virtual memory to store data, it creates a file -which allows the system to run more applications that can actually fit in RAM- known as
Page file
What is the hard drive composed of ?
Several coated platters ( round, thin plates of metal) stacked onto a spindle
what is created when data is saved on the hard drive platter?
Magnetized spots ( iron oxide coating) - tracks and sectors
Hard drive that uses thinner cables and transfers data more quickly than older types
Serial ATA ( advanced technology attachment)- graphic designers and software developers benefit from it
Access time is measured in
milliseconds
Portable non-Volatile storage device also known as thumb or jump drive
Flash drive
Format for read-only optical discs
CD- ROM, DVD-ROM or BD-ROM
Recordable formats for optical discs
CD-R, DVD-R, BD-R
Read/writeable format for optical disks
CD-RW, dvd-rw, bd-rw
For CDs, the X after each number
represents the transfer rate of :
150 kB per second
a 1X DVD-ROM drive
provides a data transfer rate of approximately
1.3MBof data per second
Blu-ray technology defines 1X speed as
36 MB
per second.
This external hard drive offers extra storage up to
1TB
Why do some subsystems have their own fan?
To remove heat
The number of bits the video card
uses to represent each pixel (or dot) on the monitor, is referred to as
bit depth
the standard proportion in width to height for a computer monitor
aspect ratio
Allows you to see more
on your screen.
screen resolution
a special type of speaker designed to more faithfully reproduce low frequency sounds.
subwoofer
a device that connects to one port, such as a USB port
An expansion hub
