1.Anti-Static Wrist Strap
- Worn by computer technicians to prevent damaging static discharge while working on static-sensitive equipment. Antistatic Wrist Straps work continuously, discharging electricity harmlessly as it's generated. A must for anyone who frequently works inside a computer. All wrist straps include a grounding cord attachment
- Electrostatic Protection Wrist Strap: Required
Used to safely dissipate static electricity so that it does not damage sensitive electronic equipment. Do not get the self-contained type that claim to dissipate static electricity without being connected to ground; they do not work as well as their wired counterparts.

2. After installing a new computer component why is it important to obtain the most current driver for it?
----ans. it is important to obtain the most current driver for the reason that the manufacturers of the new computer component updates new driver which is compatible for it.There are also new features added for it.
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.
Some Windows programs are virtual device drivers. These programs interface with the Windows Virtual Machine Manager. There is a virtual device driver for each main hardware device in the system, including the hard disk drive controller, keyboard, and serial and parallel ports. They're used to maintain the status of a hardware device that has changeable settings. Virtual device drivers handle software interrupts from the system rather than hardware interrupts.
In Windows operating systems, a device driver file usually has a file name suffix of DLL or EXE. A virtual device driver usually has the suffix of VXD.

3 Step in Installing a Peripheral
A computer device, such as a CD-ROM drive or printer, that is not part of the essential computer, i.e., the memory and microprocessor. Peripheral devices can be external -- such as a mouse, keyboard, printer, monitor, external Zip drive or scanner -- or internal, such as a CD-ROM drive, CD-R drive or internal modem. Internal peripheral devices are often referred to as integrated peripherals.
Adding a Peripheral Device to a System
Adding a new peripheral device that is not-pluggable usually involves the following:
Shutting down the system
Connecting the device to the system
Rebooting the system
How to Add a Peripheral Device to add the following devices that are not hot-pluggable to a system:
C D-ROM
Secondary disk drive
Tape drive
SBUS card
In some cases, you might have to add a third-party device driver to support the new device.
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. Shut down the system.
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.
For the location of power switches on any peripheral devices, refer to
the hardware installation guides that accompany your peripheral devices.
7.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 f r information on installing and connecting the device.
8. 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.
How to Add a Device Driver
This procedure assumes that the device has already been added to the system. If not, see What You Need for Unsupported Devices.
----1.Become superuser.
----2.Place the tape, diskette, or CD-ROM into the drive.
----3.Install the driver.
----4.Verify that the package has been added correctly

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 that can be 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 drive into 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 be upgraded without the risk of losing data. It also simplifies backup and recovery of data files

6. Explain what a software patch is.
A patch is a small piece of software designed to fix problems with or update a computer program or its supporting data. This includes fixing bugs, replacing graphics and improving the usability or performance. Though meant to fix problems, poorly designed patches can sometimes introduce new problems (see software regressions).
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
