The biggest technical difference between Windows and MS-DOS is the _______________.  The _______________ is a database that keeps track of hardware and software configuration and setup information.

The objects in the COntents window are viewed in one of several formats.  You can use the View menu bar or the View icon on the tool bar to change the view (Icon, Tile, List, Details, and the Thumbnail).  The _________view is the default but is difficult to use if you are concerned with file sizes, the dates they were modified, or if you have a list of files that could be sorted for easier viewing.  We recommend switching to the _____________view.

______________________ is generally used to describe any memory that does not lose data when the power is removed.  Its opposite is _______________, which lose data when power is removed.  ____________ is the physical memory package, usually a large IC on the motherboard.

The _______________________ contains information that points to the location of the operating system. In DOS and WIndows 95/98 that file was __________________.  In Windows NT/2000/XP that file is _______________.  In earlier operating systems the key files were ____________ and __________________. In Windows NT, 2000, and XP, _________________ is the key file.

Microsoft recommends that you only used _______________ drivers, which also come with a special Windows logo stating they are designed for Windows. 

The ___________________ and _________________ are an attempt to verify that you are the authentic intended user, and not an imposter.  The process of verifying that the person typing is the actual authorized user is called ____________________.

One final approach takes a bit of work upfront but it works very quickly.  You can make a copy of your entire system partition and put it on CD or another hard drive.  This copy is called _______________, and is an exact duplicate of your drive.

With ___________________ drives, You connect a single drive to a port on the motherboard, and that's it.

DVD capacity table: DVD Type = Max Capacity; Single-layer, single-sided = _______________GB; Single-layer, double sided = _____________GB; Dual-layer, single sided = ______________________ GB; Double layer, double sided = ___________GB.

The problem is how does the CPU know when a device needs attention?  It works the same way a student gets the attention of the instructor.  Each device will "raise its hand" and wait for the CPU to respond.  Each device will use the raising its hand  version known as, a _____________________.

A ___________________ works having an electron gun at the long narrow end which is heated and emits a stream of high-speed electrons in the direction of the large end of the tube.

______________ displays are known for their sharp image quality, low power usage, light weight, and thin profile.  

Because of the level of complexity and the millions of microscopic transistors that need to be printed onto the LCD substrate,  LCDs are fairly expensive and difficult to manufacture.  In a standard 1,024 x 768 color laptop screen, there are more than __________________ transistors.  If a single transistor doesn't operate properly,  the associated pixel loses its sub-pixel color.

Microsoft and Intel jointly developed the ______________________ (APM) specification.  These specifications define the _____________________ between the hardware and the operating system.  In order for a computer to provide power management it must comply with both of these standards, DPMS for monitors, APM on the computer side.

In some peer-to-peer networks,  a single machine is assigned to be the ________________________.

The next step-up is the ________________________.  This network requires that one computer,  the server, is dedicated to acting as a central repository of account and login information, and usually files and applications.

___________________________ establish the rules on how computers talk to and understand each other.

In a ________________________, all devices are connected to a single linear cable.

In a _______________________,  all workstations and servers are connected in a closed loop.

_______________________ (NICs) link the computer to the network cable systems.

_________________________ consists of two insulated strands of wire twisted around each other to form a pair.

Twisted-pair cable is limited to a maximum lenght of _________________, and it requires a hub or a switch to connect more than two computers.  __________________ is by far the most popular type of cabling, even with its length limitation.

As with any technology,  the ____________________ has its downside.  For one thing it has limited throughput.  The theoretical maximum speed of today's fastest wireless technology is __________________Mbps.

The ______________________________________________ has specified several categories of twisted-pair cable.  Not all of these are approved for data communications.

Operating in the same 2.4Ghz range as the 802.11B,  the newer __________________ standard offers the same speed as 802.11A at 54Mbps, but is backward-compatible with 802.11B.  As of today this is the most widely used system.

______________________ is a fast, full time connection to the internet, and does not tie up a telephone line as it can operate at the same time as a telephone call.  Speed is between ___________________Kbps; depending on the type and how far you are from the nearest substation.

The Intel chipset system uses the ___________ device to control the transfer data into and out of the SATA ports.

• CPU

• GMCH

• ICH

It is important to know that ___________________________ itself does not cause electrical damage.  The damage occurs when these extremely high voltages are discharged in an uncontrolled manner, typically through a semiconductor such as an integrated circuit.

A time - tested way to increase system performance is to __________________________.  However,  when upgrading memory there are several precautions that must be observed to insure a smooth upgrade.

Most experienced system administrators will ____________________________, which effectively closes a potential security hole.  An amazing number of people use the default administrator account with their first name as password...and the hackers know this.

______________________ is most often defined as the act of playing a ruse to entice you to give up personal information.

Installing an optical drive is similar to installing a ___________________.

______________________ are used to connect devices to the motherboard and therefore allow the flow of data between that device and other devices in the computer.

_____________________ uses a serial data transfer method rather than parallel.

The best source of information to check before obtaining memory is the _____________________ that comes with the computer or motherboard.  This source will generally list the type of memory required,  how many modules are possible,  and how to install them on the motherboard. 

Beyond the remote workstation sits the __________________ network.  As its name implies,  this network is a collection of similar computers with a common connection.  This is the type of network created when several computers in an office are interconnected.

The key aspects of a peer-to-peer network are that no single computer is in charge of the others, and each computer is independent of the others.
