Answer: An antistatic wrist strap, ESD wrist strap, or ground bracelet is an antistatic device used to prevent electrostatic discharge (ESD) by safely grounding a person working on electronic equipment and avoid the components to destroyed.
A wrist grounding strap is used to prevent electrostatic discharge when handling computer components. Just like a shock when walking on carpet can carry several thousand volts, it destroys computer components.

2. After installing a new computer component why is it important to obtain the most current driver for it?
Answer: A device driver is a program that controls a particular type of device that is attached to your computer. There are device drivers for printers, displays, CD-ROM readers, diskette drives, and so on. When you buy an operating system, many device drivers are built into the product. However, if you later buy a new type of device that the operating system didn't anticipate, you'll have to install the new device driver. A device driver essentially converts the more general input/output instructions of the operating system to messages that the device type can understand. You need to have a newer version of your device driver because a newer version of a device driver has new features on it.

3. What are the steps required to install a peripheral device?
Answer:
Adding a Peripheral Device to a SystemAdding a new peripheral device that is not-pluggable usually involves the following:
1.Shutting down the system
2.Connecting the device to the system
3.Rebooting the system
How to Add a Peripheral Device to add the following devices that are not hot-pluggable to a system:
CD-ROM
Secondary disk driveT
ape drive
SBUS card
In some cases, you might have to add a third-party device driver to support the new device.For information on hot-plugging devices, see Chapter 6, Dynamically Configuring Devices (Tasks).How to Add a Peripheral DeviceBecome superuser.(Optional) If you need to add a device driver to support the device, complete the procedure How to Add a Device Driver.Create the /reconfigure file.# touch /reconfigureThe /reconfigure file causes the Solaris software to check for the presence of any newly installed devices the next time you turn on or boot your system.Shut down the system.# shutdown -i0 -g30 -y-i0Brings the system to the 0 init state, which is the appropriate state for turning the system power off for adding and removing devices.-g30Shuts the system down in 30 seconds. The default is 60 seconds.-yContinues the system shutdown without user intervention. Otherwise, you are prompted to continue the shutdown process.Select one of the following to turn off power to the system after it is shut down:For SPARC platforms, it is safe to turn off power if the ok prompt is displayed.For x86 platforms, it is safe to turn off power if the type any key to continue prompt is displayed.Turn off power to all peripheral devices.For the location of power switches on any peripheral devices, refer to the hardware installation guides that accompany your peripheral devices.Install the peripheral device, making sure that the device you are adding has a different target number than the other devices on the system.Often, a small switch is located at the back of the disk for selecting the target number.Refer to the hardware installation guide that accompanies the peripheral device for information on installing and connecting the device.Turn on the power to the system.The system boots to multiuser mode, and the login prompt is displayed.Verify that the peripheral device has been added by attempting to access the device.For information on accessing the device, see Accessing Devices.
Installing a Peripheral
If you add a first or even second device to a basic system, you may have no conflicts, but as you add more, the chances are greater for a conflict. Each device uses one or more resources of the computer, and two devices cannot generally share the same one. If the CD-ROM, sound card, scanner, etc., that you add uses the same setting as an existing board, you have to figure out where the conflict is and choose another resource.
ISA, EISA AND Micro Channel Buses
The ISA bus was the original PC bus and does not have any advanced installation features. PCs that used the EISA and Micro Channel buses still had configuration problems, but had two advantages. First, when a board is added, a setup program was run to install the board, and conflicts were identified ahead of time. Although you still had to participate in this "plug and tell" capability, it was better than the "plug and hope" offered by ISA-bus cards.
Secondly, the boards were configurable by software, which eliminated the need to set switches or jumpers on the boards themselves. If you have to change a setting, you did not have to pull the board out of the socket in order to do it. You ran the setup program and selected the configuration option.

4. If a newly installed peripheral device does not function properly what steps can be taken to correct the problem?
Answer: Check if the product or the hardware you bought has no defect or company defects.
You should also check for driver updates for all your peripheral devices. If you're up to date, and you started having issues around the time you last updated a driver, try backing down to a lower version.

5. Explain the technique used to help protect data on a hard drive when doing a clean install?
Answer: One of the techniques available to help protect data is to divide the hard drive
into multiple partitions. With a clean install, many technicians prefer to create one CCNA Discovery 4.0 Jonesr0

partition for data and a separate partition for the OS. This enables an OS to be
upgraded without the risk of losing data. It also simplifies backup and recovery of
data files.

6. Explain what a software patch is.
Answer: A patch is a piece of program code that can correct a problem or enhance the
functionality of an application program or OS. They are usually provided by the
manufacturer to repair a known vulnerability or reported problem. CCNA Discovery 4.0 Jonesr0
