Quiz# 1:

Questions to be answered.

1. What is the reason for technitians to wear special wrist grounding straps?

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. The fibers are usually made of carbon or carbon-filled rubber, and the strap is bound with a stainless steel clasp or plate. They are usually used in conjunction with an anti-static mat on the workbench, or a special static-dissipating plastic laminate on the workbench surface.

The wrist strap is connected to ground through a coiled retractable cable and 1 megaohm resistor, which allows high-voltage charges to leak through but prevents a shock hazard when working with low-voltage parts. Where higher voltages are present, extra resistance (0.75 megaohm per 250V) is added in the path to ground to protect the wearer from excessive currents; this typically takes the form of a 4 megohm resistor in the coiled cable (or, more usually, a 2 megohm resistor at each end). Very cheap wrist straps do not have conductive fabric and instead use the fabric to hold the metal plate against the skin, which can result in reduced ESD protection over time as the metal corrodes.
Wrist straps in industry usually connect to Earth Bonding Points (part of the grounding system) via either a 4 mm plug or 10 mm press stud, whereas personally owned straps are likely to be connected to ground via a
crocodile clip.
In addition to wrist straps, ankle and heel straps are used in industry to bleed away accumulated charge from a body. These devices are usually not tethered to earth ground, but instead incorporate high resistance in their construction, and work by dissipating electrical charge to special floor tiles. Such straps are used when workers need to be mobile in a work area and a grounding cable would get in the way, such as in an
operating theatre.

2.) After installing a new computer component why is it important to obtain the most current driver for it?

It is required that we install the proper drivers for a certain OS and the hardware used by our computer. Because it may not funtion properly if you intalled a different driver or sofware for a certain driver or the softare is not updated properly. It is important to obtain the most compatible driver or softwares for your computer for it to function properly and no errors may occur.

Source: none.

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.

Some of the more common peripheral devices are printers, scanners, disk drives, tape drives, microphones, speakers, and cameras. Peripheral devices can also include other computers on a network system. A device can also refer to a non-physical item, such as a pseudo terminal, a RAM drive, or a virtual network adapter.


Steps:
1.) Install or connect the device to your computer.
2.) Install the proper software for the certain device.
3.) Configurate the software using its SETUP options.
4.) Use the device thoughrouly.

4.) If a newly installed peripheral device does not function properly what steps can be taken to correct the problem?

First you must check if the compabability of a certain device you installed was compatible for your computer. Then check the handware and software you installed as well. Then you may re-install the software for your device so that you can fix the errors you may encounter. Check also the configurations of your device so that you can determine that the divice is already ready to use and it is functional.

Source: none.

5.) Explain the technique used t0 help protect data on a hard drive when doing a clean install?

In information technology, backup refers to making copies of data so that these additional copies may be used to restore the original after a data loss event. These additional copies are typically called "backups." Backups are useful primarily for two purposes. The first is to restore a state following a disaster (called disaster recovery). The second is to restore small numbers of files after they have been accidentally deleted or corrupted. Data loss is also very common.

Since a backup system contains at least one copy of all data worth saving, the
data storage requirements are considerable. Organizing this storage space and managing the backup process is a complicated undertaking. A data repository model can be used to provide structure to the storage. In the modern era of computing there are many different types of data storage devices that are useful for making backups. There are also many different ways in which these devices can be arranged to provide geographic redundancy, data security, and portability.
Before data is sent to its storage location, it is selected, extracted, and manipulated. Many different techniques have been developed to optimize the backup procedure. These include optimizations for dealing with open files and live data sources as well as compression, encryption, and de-duplication, among others. Many organizations and individuals try to have confidence that the process is working as expected and work to define measurements and validation techniques. It is also important to recognize the limitations and human factors involved in any backup scheme.

6.) Explain what a software patch is:

A patch, or diff, is a record of changes made to a resource. Typically a patch will add a new feature, fix a bug, or add documentation to the project.

Patches are the preferred way to submit contributions to open development projects such as open source software. Various tools are available to help with patches. These tools make it very easy to create and manage patches for project outputs such as source code and documentation.

Some people wonder why they should put the effort into providing a patch. They may consider it additional work over and above the development effort of making the modifications in the first place. If everyone thought like that there would be no community and therefore no open development, so clearly it is in everyone's interest to provide patches. However, there is a second, much more selfish reason for creating and submitting a quality patch: it makes it easier to maintain your use of the project outputs.

At some point in the future an organisation is likely to want to utilise the latest and greatest release of the project outputs. If that organisation's staff has failed to work with the community in order to have their local modifications accepted they will need to reapply all changes, or lose them. That is, the organisation will be paying its staff to make each change twice.
It is easy to ignore this fact. After all, each change seems insignificant and easy to reapply. However, each change is cumulative, and since the project has been progressing independently of your changes it is quite possible that the application of your modifications will no longer be a simple activity.

Installation Process in Windows XP:

Most new computers come with Windows XP installed, so many people never have to install it. However, you may need to install Windows XP if:

You replaced your hard disk drive with a new hard disk drive that does not have Windows XP installed.

You are reinstalling Windows XP on a computer because you want to clean off your hard drive and remove any unwanted programs, such as spyware.

You purchased a computer without an operating system.

Fortunately, you do not need to be a computer expert to install Windows XP. Installing Windows XP is a straightforward process that takes between one to two hours. Of that time, you need to be present for only about 30 minutes.


You have the Windows XP CD.

Check

You have the product key available. The product key is located on your Windows XP CD case and is required to install and activate Windows XP.

Check

Your computer hardware is set up. At a minimum, you should connect your keyboard, mouse, monitor, and CD drive. If available, you should connect your computer to a wired network.

Check

You have Windows XP drivers available. Drivers are software that Windows XP uses to communicate with your computer’s hardware. Most new computers include a CD containing drivers. If you do not have drivers available, Windows XP may already include drivers for your hardware. If not, you should be able to download them from your hardware manufacturer’s Web site after you set up Windows XP.

Check

If you are reinstalling Windows XP on an existing computer, you need a backup copy of your files and settings. The installation process will delete all of your files. You can use the File and Settings Transfer Wizard to store your files and settings on removable media and then restore them after installation is complete.

25.January.2006 -- The Solaris 10 Operating System (Solaris OS) just got better. The newest release of the software includes a host of new features, such as:

  • GRUB-based (GRand Unified Bootloader) boot loader for simplification of installation and boot of the Solaris 10 OS on x64/x86 platforms
  • Sun Update Connection, which provides immediate access to the latest patches and fixes, or software updates
  • Solaris Containers improvements to enable customers to install and update patches dynamically within a Container
  • Improved network performance
  • Improved memory management
  • Updated peripheral support including iSCSI support
  • Integrated bug fixes

Simplified Installation and Updating

The Solaris 10 Operating System 1/06 integrates two applications that simplify installing and updating. The popular GRUB boot loader, traditionally used on Linux, simplifies and accelerates the boot process for alternate operating systems from a Solaris system or USB device.

Sun Connection software enables immediate access to Sun Connection Services, so you can get the latest software updates (including security patches and fixes), as they become available.

Market Momentum

Nearly four million people have chosen the Solaris 10 OS since it became available just over a year ago. The list of supporting independent software vendors grows longer each day.

Customers are seeing remarkable performance improvements after deploying the Solaris 10 OS in their environments, due to networking enhancements, a radically improved kernel, special optimizations for memory allocation, and chip multithreading (CMT). The Solaris 10 software's unique Solaris Dynamic Tracing feature (DTrace) yields additional application performance gains by tuning applications.

"We favor Solaris because we've seen it's faster than Linux for the same applications with no changes, especially large memory footprint applications, including simulations and large database cache applications," says Neal Tisdale, vice president of Software Development at NewEnergy Associates, a Siemens Company.

"We also like the features of DTrace and the Sun compilers. These are pulling my development teams over into Solaris."

What's new in Windows 7: Faster & easier


Windows 7 was built around your feedback, so you'll see a lot of things you've asked for. You asked us to make everyday tasks faster and easier, make your PC work the way you want it to, and make new things possible. And that's exactly what we're doing. Click below to see how it's coming to life!

mproved taskbar and full-screen previews

The taskbar at the bottom of your screen is what you use to switch between the applications you've got open. In Windows 7 you can set the order in which the icons appear and they'll stay put. They're easier to see, too. Click once on the new large icons or bigger preview thumbnails and you're ready to go. You can even see a full screen preview before switching to the window.

New Windows 7 taskbar

Get the picture: See what's open with previews and easily control your Windows experience with the new Taskbar.


Better device management

One of the great things about PCs is how they let us use such a wide array of devices. In the past, you had to use several different screens to manage different types of devices. But With Windows 7, you'll use a single Devices and Printers screen to connect, manage, and use whatever printers, phones, and other devices you have on-hand.

Gathering place: Devices and Printers collects device details in a single location

All together now: See all your devices in one spot

A new technology in Windows 7 called Device Stage takes device management a step further. Device Stage helps you interact with any compatible device connected to your computer. From Device Stage you can see device status and run common tasks from a single window. There are even pictures of the devices which makes it really easy to see what's there. Here's a list of products that take advantage of Device Stage.

Device Stage puts device features front and center

HomeGroup

Setting up a home network can be complicated. With PCs running Windows 7, a home network will be easier to setup and a lot more useful. HomeGroup makes it easier to connect to other computers and devices on a wireless home network, so you can share files, photos, music, and printers throughout your home. To use HomeGroup, you’ll need to have at least two PCs running Windows 7. Once you've set up a homegroup, you can use the Network and Sharing Center to choose what you share with other homegroup members.
