HARDWARE COMPONENTS

CPU

1.      CPU stands for ________________ _______________ _______________.

2.      If comparing a computer system to a human, the CPU would be the _______________.

3.      _______________ and _______________ are the two biggest CPU manufacturers for the PC.  They have quite a history of competition including some impressive lawsuits.

4.      The most important attribute in a CPU is the clock ________________ or clock _____________ or clock ____________.  However, since the mid-2000s, this has become a less important way to compare CPUs of different brands.  More on this later.

5.      The CPU’s frequency is measured in _______________.  This is the amount of cycles per second.  During each cycle, the CPU generally executes a command.

6.      The short form for gigahertz is _____________ and the short form for megahertz is ______________.

7.      The term hertz means _______________ per second.

8.      A CPU’s job is to _______________ the commands that it receives.  The commands are lined up one after another waiting in line to get to the CPU.

9.      Newer CPUs contain multiple ______________.  Each one is able to run its own commands.  Therefore, multiple commands can be executed at the same time (in parallel).  The introduction of this new technology has made comparing CPU speeds more difficult.

 

MOTHERBOARD

1.      The motherboard is the hardware component where all computer _____________ connect. 

2.      PCB stands for ______________ ______________ ______________.  The motherboard is the largest PCB in your computer.  Other PCBs connect to it via expansion slots.

3.      The CPU, _______________ slots (for extra cards) and ______________ slots (for memory) are all on the motherboard.  (The CPU and memory will be discussed in their own sections.)

 

RAM

1.      RAM stands for ____________ _______________ _______________.  The “RA” refers to the fact that any data on the chip can be access in the same amount of time.  An example of the opposite of this would be a tape back-up where data at one end can be accessed quickly but data at the other end requires the tape to be forwarded to that end before accessing it.

2.      Each piece of RAM is called a ______________, or a _____________, or a ______________.

3.      RAM, like the hard drive, is a form of ____________.  While the hard drive stores all of the computer’s data, RAM  stores system information that is soon likely to be used by the CPU.

4.      The reason that RAM stores a part of the hard drive’s information is that RAM is ______________ memory.  It would delay the CPU too much to constantly make requests to the hard drive for information.  Of course, the more RAM a system has, the more likely that required information will be stored in the RAM.

5.      So if RAM is faster than a hard drive, why do we even have a hard drive?  There are two reasons:

·               

·         

6.      RAM is said to be ______________ memory because it is erased if it stops being powered. 

7.      RAM plugs into a slot that is on the _______________.  There are usually 2 to 4 slots for different RAM sticks to be plugged into.

8.      The most common computer upgrade is to increase the amount of ______________ in a computer.  This is often done by simply adding another stick into an empty slot.

 

HARD DRIVES

1.      When comparing a computer to a human, the hard drive would be the human’s _____________ ______________.

2.      All _____________ is stored on the hard drive in the form of _____________.  This includes your operating system files, your application files, music files, game files, photo files, etc…

3.      If your hard drive fails, you lose all your ____________.  In this sense, it is the one truly irreplaceable part of your computer.  You can order another identical hard drive, but it won’t contain your files.

4.      _____________ , the abbreviation for hard drive, stands for _____________ _____________ ____________.

5.      SSD, a newer type of hard drive that is faster (but more expensive), stands for ___________ ____________ ____________.

6.      The primary attribute of a hard drive is its ____________.

7.      A hard drive’s size is measured in ____________.  The prefix mega means millions.  The prefix giga means billions.  The prefix tera means trillions.  Mr. Campeau’s first hard drive, in 1994, was 214 megabytes.

8.      Here is a table showing the unit of measure and its abbreviation:

VIDEO CARDS

1.      Another name used for a video card is ______________ card.  Some people also refer to it as GPU.

2.      The video card plugs in a(n) ______________ ________________ on the motherboard.

3.      The video card _____________ data from the CPU to a format that is understood by the monitor.  It saves the CPU time by allowing it to pass off some of the work.

4.      The video card has its own CPU called _____________ which stands for __________ ___________ ___________.
