You will typically set the jumper on the second hard disk to slave. See Book II, Chapter 5.

A boot sector virus prevents a system from booting because it corrupts the boot sector. See Book IX, Chapter 3.

The CMOS configuration information is stored in CMOS RAM. This special RAM chip maintains its information by using a small battery on the system board. If the battery loses its charge, then the CMOS RAM is flushed out, meaning that it will prompt you for the information such as the date and time as the system boots up. See Book II, Chapter 4.

ESD stands for electrostatic discharge and occurs when there is an inbalance of electrons between two sources. The electrons move from one object to another to create a balance and create the "shock" that we feel when we touch one another. This shock is enough to kill computer chips. See Book I, Chapter 3.

A bar code reader is a type of device that reads bar codes and converts the code into data to be used on the computer. See Book III, Chapter 2.

You should perform a Windows Update regularly to download current patches to your system. See Book IX, Chapter 3.

Only members of the Administrators group have been granted the right to load and unload device drivers, by default. See Book VI, Chapter 1.

Event Viewer is used to read, back up, and clear your event logs. See Book VII, Chapter 1.

Reducing office temperature is something that may help systems as part of a preventative maintenance plan, but it is not a reason to implement the plan. See Book IV, Chapter 1.

Ribbon cables create small walls in the path of airflow and can be replaced with rounded cables to improve airflow in most situations. See Book IV, Chapter 1.

The acronym POP stands for Post Office Protocol. See Book VIII, Chapter 4.

Virtual memory is created by using a page file, which resides on a hard drive. Disk caching uses memory to cache data from the hard drive. See Book VI, Chapter 3.

CMOS RAM is a small amount of memory that maintains the CMOS configuration information. Since this information is stored in a type of RAM, the memory has to have constant power; this power comes from the battery found on the system board. Choice A describes shadow RAM. See Book II, Chapter 3.

A bus topology must have all loose ends terminated to prevent signal bounce. See Book VIII, Chapter 1.

A parallel cable has a different style of connector at each end of the cable. The end that connects to the computer has 25 pins, and the end that connects to the printer has 36 pins. See Book II, Chapter 1.

16-bit applications can be preemptively multitasked within Windows XP by running each application in a separate memory space. See Book VI, Chapter 2.

The maximum length of a filename is 255 characters. See Book V, Chapter 4.

The system BIOS on some systems allow for testing of IRQs, memory, hard disks, CPU processing ability, and most internal components. See Book IV, Chapter 2.

SMTP is used to send mail messages over the Internet. See Book VIII, Chapter 4.

The motherboard will include I/O ports or connectors for a variety of devices, but will not typically include the devices themselves. It will include the ATA controller, and a connector to attach the ATA drive, but not the drive itself. The same would be true of USB drives; the motherboard will include the controller and connector for the USB bus, but not the actual device. See Book I, Chapter 4.

Most device settings can be modified through either the Device Manager or the device's control panel. Resource Manager and Device Arbitrator are made-up terms. See Book VI, Chapter 1.

When a 16-bit Windows application crashes, it halts other 16-bit Windows applications in the same memory space. MS-DOS-based applications and 32-bit Windows applications should continue to operate. See Book VI, Chapter 2.

Most 802.11 wireless networks have a range of 30 meters in open air. See Book VIII, Chapter 2.

The Windows 9x version of msconfig.exe is able to edit most of the startup files, while the Windows XP version is not able to edit autoexec.bat. See Book VI, Chapter 4.

Disk latency is the time it takes to move the sector that has the data under the read/write heads. See Book II, Chapter 5.

There is no specific area of RAM that is used for caching printer data. See Book VI, Chapter 3.

Windows XP supports cooperative and preemptive multitasking. See Book VI, Chapter 2.

Modems occupy one of those dual roles that can also be held by network cards, as they allow for information to enter and leave the computer. See Book I, Chapter 4.
