-In order for us to avoid groundings while we are performing a task or we are handling a electronic device.
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. It consists of a stretchy band of fabric with fine conductive fibers woven into it

2. After installing a new computer component why is it important to obtain the most current driver for it?
- Because it is possible that your computer will not function properly if we use different drivers that are not compatible with our OS as well as our Hardware, we must choose the right thing for us to be satisfied.

3. What are the steps required to install a peripheral device?
-A peripheral is a device attached to a host computer behind the chipset whose primary functionality is dependent upon the host, and can therefore be considered as expanding the hosts capabilities, while not forming part of the system's core architecture.
- Steps to install a peripheral device.
Adding 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
Use How to Add a Peripheral Device to add the following devices that are not hot-pluggable to a system:
1.CD-ROM
2.Secondary disk drive
3.Tape drive
4.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 Device
1.Become superuser.
2.(Optional) If you need to add a device driver to support the device, complete the procedure
How to Add a Device Driver.
3.Create the /reconfigure file.
4.The /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.
-i0
Brings the system to the 0 init state, which is the appropriate state for turning the system power off for adding and removing devices.
-g30
Shuts the system down in 30 seconds. The default is 60 seconds.
-y
Continues the system shutdown without user intervention. Otherwise, you are prompted to continue the shutdown process.
5.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.
6.Turn off power to all peripheral devices.
7.For the location of power switches on any peripheral devices, refer to the hardware installation guides that accompany your peripheral devices.
8.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.
9.Verify that the peripheral device has been added by attempting to access the device.
For information on accessing the device, see Accessing Devices.

4. If a newly installed peripheral device does not function properly what steps can be taken to correct the problem?
- 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?
-One of the techniques available to help protect data is to divide the hard driveinto multiple partitions. With a clean install, many technicians prefer to create one partition for data and a separate partition for the OS. This enables an OS to beupgraded without the risk of losing data. It also simplifies backup and recovery ofdata files.
6. Explain what a software patch is.
-A patch is a small piece of software designed to update or fix problems with a computer program or its supporting data.
