If there’s No technology, what would happen to the world?

Talking about technology, almost everyone in the world will definitely cannot live without it and need it wherever they go. We all know pretty well all the good things we had when there’s a technology so I won’t mention much on that part and will explain more on the opposite. Because of the misused of technology, it brings disaster to our life and even affect the earth.   

When it comes to a technology that never existed in our daily life before, imagine that if we don’t know anything about the existing of technology or not yet existing, human can live without it and live their life like thousand years back then without any problem. Yes, without technology existing, our life will be like the old days of our great-great-grandparents. For instance, when the people go out of town, if it is far away, they will wake up early in the morning and walk all the way or maybe riding a bicycle. Most likely, the air people breathe in are fresh.

 I have seen this new technology create for housework where you don’t need to move your body around, just sit and take the remote control with you. When you need to throw your rubbish away, just click the remote controller and it will comes to you same goes to cleaning the floor. I think this was a good idea but not for our body as we might become lazier if depends too much on it unless if that person have difficulty moving than this would be useful to them.

Majority of people have their own cars nowadays. The more people driving cars, the more likely accident occur as it causes death which increasing rapidly every year. At the same time, it causes air pollution, noise pollution and etc. When people misused of mobile and laptop like they are too addicted and never give themselves some rest, it actually affect their health. There was this teenager who’s addicted in playing computer games without eating and sleeping for the whole 3 days and he passed away.

There is good and bad with and without technology. Here’s the good side of what happen if there’s no technology:

–       People will become more active at work and healthier without depending too much on technologies / exercise body (healthier activity).

–       Less likely to occur any kind of accident (cars, weapons, house burning cause from overuse electricity, anything that will cause explosion, pollution, and etc) which will harm/loss someone’s life even living things and earth.

There are a lot of bad sides of having no technology and below are a few to mention:

–       All the things take longer to produce for example food, if we want to eat vegetables and fruits, we need to wait it to harvest.

For cloth, to make more cloth needs more workers and it take days and weeks to   complete clothes. As for food and cloth, we can live without technology as it is not a whole part from technology just that without it, work seems taking longer than ever.

For car, people will have to walk all the way from where they are, if the places they go are too far, maybe using old method either by bicycle or boat.

If there’s no device like mobile, laptop and etc people will find it hard to contact others especially when there’s an emergency.

– For light, we cannot see the whole area clearly when walking down the path of dark area, only when with a light candle for an example. As for that, the world might seem darker during night time.

–       Some sickness cannot be cure and we wouldn’t know what cause it.

All of the things stated above are just some predictions and comparisons of what happen if there’s no technology exists.

Virtualization and its effect on to the world

Virtualization is the creation of a virtual version of something, such as operating system, a server, a storage device or network resources.

Operating system virtualization is the use of software to allow a piece of hardware to run multiple operating system images at the same time.

There are 3 areas of IT where virtualization is making headroads, network virtualization, storage virtualization and server virtualization :

• Network virtualization is a method of combining the available resources in a network by splitting up the available bandwidth into channels, each of which is independent from the others, and each of which can be assigned (or reassigned) to a particular server or device in real time. The idea is that virtualization disguises the true complexity of the network by separating it into manageable parts, much like your partitioned hard drive makes it easier to manage you r files.
• Storage virtualization is the pooling of physical storage from multiple network storage devices into what appears to be a single storage device that is managed from a central console. Storage virtualization is commonly used in storage area networks (SANs).
• Server virtualization is the masking of server resources (including the number and identity of individual physical servers, processors, and operating systems) from server users. The intention is to spare the user from having to understand and manage complicated details of server resources while increasing resource sharing and utilization and maintaining the capacity to expand later.

Virtualization can be viewed as part of an overall trend in enterprise IT that includes autonomic computing, a scenario in which the IT environment will be able to manage itself based on perceived activity, and utility computing, in which computer processing power is seen as a utility that clients can pay for only as needed. The usual goal of virtualization is to centralize administrative tasks while improvingscalability and work loads.

The effect of virtualization on Networking

Virtualization offers a host of benefits, but it also increases complexity. A new depth of understanding is required, particularly in configuring virtualization hosts to maximize reliability, bandwidth, and ease of management. With proper configuration, virtual servers can enjoy the same basic network resources as physical servers did in days gone by.

7 side effects of sloppy virtualization

Here are the reasons Gartner says virtualization is no IT cure-all:

1. Magnified failures. In the physical world, a server hardware failure typically would mean one server failed and backup servers would step in to prevent downtime. In the virtual world, depending on the number of virtual machines residing on a physical box, a hardware failure could impact multiple virtual servers and the applications they host.

“Failures will have a much larger impact, effecting multiple operating systems, multiple applications and those little tiny fires will turn into big fires fast,” Coyle said.

2. Degraded performance. Companies looking to ensure top performance of critical applications often dedicate server, network and storage resources for those applications, segmenting them from other traffic to ensure they get the resources they need. With virtualization, sharing resources that can be automatically allocated on demand is the goal in a dynamic environment. At any given time, performance of an application could degrade, perhaps not to a failure, but slower than desired.

3. Obsolete skills. IT might not realize the skill sets it has in-house won’t apply to a large virtualized production environment until they have it live. The skills needed to manage virtual environments should span all levels of support, including service desk operators who may be fielding calls regarding their virtual PCs. Companies will feel a bit of a talent shortage when moving toward more virtualized systems, and Coyle recommends starting the training now.

“Virtualized environments require enhanced skill sets, and virtual training across many disciplines,” he said.

4. Complex root cause analysis. Virtual machines move — that is the part of their appeal. But as Coyle pointed out, it is also a potential issue when managing problems. Server problems in the past could be limited to one box, but now the problem can move with the virtual machine and lull IT staff into a false sense of security.

“Is the problem fixed or did you just lose it? You can’t tell in a virtual environment,” Coyle said. “Are you just transferring the problem around from virtual server to virtual server?”

5. No standardization. Tools and processes used to address the physical environment can’t be directly applied to the virtual world, so many IT shops will have to think about standardizing how they address issues in the virtual environment.

“Mature tools and processes must be revamped,” Coyle said.

6. Virtual machine sprawl. The most documented side effect to date, virtual server sprawl results from the combination of ease of deployment and lack of life-cycle management of virtual machines. The issue could cause consolidation efforts to go awry when more virtual machines crop up than there are server administrators to manage them.

“The virtualized environment is in constant flux,” he said.

7. May be habit forming. Once IT organizations start to use virtualization, they can’t stop themselves, Coyle said. He offered tips to help curb the damage done from giving into a virtual addition.

 

Function of software for preventive maintenance

 

 

Check for hard disk error

1. Open Computer by clicking the Start button , and then clicking Computer.

2. Right-click the hard disk drive that you want to check, and then click Properties.

3. Click the Tools tab, and then, under Error-checking, click Check Now.  If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

4. To automatically repair problems with files and folders that the scan detects, select Automatically fix file system errors. Otherwise, the disk check will simply report problems but not fix them.

To perform a thorough disk check, select Scan for and attempt recovery of bad sectors. This scan attempts to find and repair physical errors on the hard disk itself, and it can take much longer to complete.

To check for both file errors and physical errors, select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors.

4. Click Start.

Depending upon the size of your hard disk, this may take several minutes. For best results, don’t use your computer for any other tasks while it’s checking for errors.

Defrag hard disk volume

Fragmentation makes your hard disk do extra work that can slow down your computer. Removable storage devices such as USB flash drives can also become fragmented. Disk Defragmenter rearranges fragmented data so your disks and drives can work more efficiently. Disk Defragmenter runs on a schedule, but you can also analyze and defragment your disks and drives manually. To do this, follow these steps:

To defragment your hard disk

1. Open Disk Defragmenter by clicking the Start button . In the search box, type Disk Defragmenter, and then, in the list of results, click Disk Defragmenter.

2. Under Current status, select the disk you want to defragment.

2. To determine if the disk needs to be defragmented or not, click Analyze disk.  If you’re prompted for an administrator password or confirmation, type the password or provide confirmation.

Once Windows is finished analyzing the disk, you can check the percentage of fragmentation on the disk in the Last Runcolumn. If the number is above 10%, you should defragment the disk.

3. Click Defragment disk.  If you’re prompted for an administrator password or confirmation, type the password or provide confirmation.

Disk Defragmenter might take from several minutes to a few hours to finish, depending on the size and degree of fragmentation of your hard disk. You can still use your computer during the defragmentation process.

Preventive maintenance for PC and its steps

Preventive Maintenance is taking regular action to take care of your computer before problems occur.

Following these few steps will decrease the chances of your computer having major problems down the road.

All Users

Restart your computer. It is best to restart your computer on a regular basis, at least once per week. Windows computers especially benefit  from regular restarts.

Monitor your hard drive. Keep at least 10% of your hard drive’s capacity free. On a 40 GB drive, this means you need to keep at least 4 GB free.

Let your laptop battery run low on occassion. To keep your laptop battery in good condition, allow it to run down to a low charge and recharge it to varying levels, rather than to the same level every time.

Backup, backup, backup. Although not really a “maintenance tip”, it’s important to never rely on only one copy of your important documents (such as your doctoral thesis), and to not rely on ACU’s backup program, which is a safety net, but not a fail-proof safety net. If you care about your documents, it’s best to store them on at least three different media (hard drive, network drive, CD, flashdrive, as a Google Email attachment, etc) stored in three different locations. When working on a document, you might want to consider saving the document every five minutes or every paragraph, alternating between document names (save it as “MyDoc.doc”, then as “MyDoc-2.doc” the next save, then back to “MyDoc.doc” the third save, etc), or better, alternating between two locations (the local hard drive, a network drive, then the local hard drive, etc).

Windows Users

Clean the hard drive of temporary files. Your computer collects temporary files that can waste a good portion of your hard drive space.

To do this, you need to run the Windows Disk Cleanup Utility. Open “My Computer” and right click on the main hard drive. Select “Properties” and you will find the “Disk Cleanup” button on the “General” tab. Click once on the “Disk Cleanup” button to initiate the process. You can also set this to run automatically by going to “Start”, “All Programs”, “Accessories”, “System Tools”, “Scheduled Tasks”. Double-click the icon labeled “Add Scheduled Task” which will initiate the “Scheduled Task Wizard”. Click “Next” and choose “Disk Cleanup” from the populated list. In the next window you can specify how often you want it to run, then click “Finish”.

Defragment your hard drive. When you save a file, your computer will often split it into different physical locations on the hard disk. This is known as fragmentation. It is problematic because being split into different places makes it take longer to read the file. When you defragment your hard drive, it puts the fragments together requiring less work of your computer.

To do this, you need to run the Windows Defragment Utility or Diskeeper (an ACU-supported application). Open “My Computer” and right click on the main hard drive. Select “Properties” and you will find the “Defragment Now…” button on the “Tools” tab. (This should automatically open the Diskeeper application if you have it installed on your computer.) Choose the option in the bottom-left navigation pane to “Set it and Forget it.” Select the top option, “Primary Defragmentation Job Properties” and check the box next to “Enable the Primary Defragmentation Job to run on selected volumes”. You can select how often you want the defragmentation to run. Click “OK” when finished.

Check the hard disk for errors. Errors can occur on your hard drive and if not corrected may cause quite a problem. This task can occur weekly or monthly if you prefer.

The error-checking utility can be found in the properties of your hard drive. Open “My Computer” and right click on the main hard drive. Select “Properties” and you will find the “Check Now…” button on the “Tools” tab. Click the “Check Now…” button to initiate the process. Select the two options “Automatically fix file system errors” and “Scan for and attempt recovery of bad sectors”. Click “Start”.

Don’t install unnecessary programs. Try to refrain from installing programs like screen savers, instant messaging programs, desktop search utilities, toolbars, mouse cursors, and weather buglets, etc. Although these things may not cause problems, they’ve done so often enough that they have the reputation for causing problems. They also make trouble-shooting and fixing problems harder.

You shouldn’t need to need to apply System Updates or Microsoft Office Updates on your ACU-owned Windows computer. Since ACU-owned computers are generally members of the ACU “network”, this step should be automatic and you won’t have to worry about doing this manually.

Macintosh Users

Apply System Updates. Go into System Preferences, then Software Update, and click on “Check Now”. If any updates are available, you can install them. There’s a good chance that this feature has been set to check for updates automatically.

Apply Microsoft Office Updates. Go into the hard drive, then Applications, then “Microsoft AutoUpdate,” and click on “Check Now”. There’s a good chance that this feature has been set to check for updates automatically.

Repair Disk Permissions. Generally this is not needed unless your Mac is exhibiting odd behavior, such as certain programs not running properly. Go into the hard drive, thenApplications, then Utilities, then start “Disk Utility”. Highlight your boot partition and click on “Repair Disk Permissions”. If you have multiple partitions or multiple drives, this screen may be confusing. If it is,  contact the Helpdesk for further assistance.

You don’t need to worry about cleaning out temporary files or defragging your hard drive on your Mac.

Uses of Tools for PC Maintenance

Basic computer tools

1. Chip extractor

 

It is designed for removing fine chips formed on processing wood and plastics. The extractor can be connected directly to a machine.

Founders of Intel

Biography of Gordon Moore

Who is Gordon Moore and what have he done?

Gordon Earle Moore was born on 3rd January 1929 and was an American Co-founder and Chairman Emeritus of Intel Corporation also the Author of Moore’s Law. Under Gordon Moore, Intel introduced the world’s first single chip microprocessor, the Intel 4004 invented by Intel engineers.

Neither Moore nor Noyce were natural-born businessmen. They were scientists, people who felt more comfortable inside the walls of a laboratory than within the four walls of an office boardroom. They had spent the majority of their youth conducting science experiments rather than doing sales, playing with molecules and electrons instead of learning about contracts and markets. However, once the two decided to branch off on their own and create Intel, they knew that their success would rest upon how well they could learn by trial and error.

“There is such a thing as a natural-born entrepreneur, for whom the entrepreneurial urge drives everything, and who can make a business out of almost anything,” says Moore. “But the accidental entrepreneur like me has to fall into the opportunity or be pushed into it. Then the entrepreneurial spirit eventually catches on.” Moore and Noyce are evidence of the fact that entrepreneurs do not necessarily have to be born as such. Through a process of discovering their passion and being unhappy with their prospects at other companies, Moore and Noyce decided to start up their own business. It was their willingness to admit their shortcomings and seek out the help of others that the two accidental entrepreneurs in fact became two of the most successful entrepreneurs in modern time.

As self-described “accidental entrepreneurs,” Robert Noyce and Gordon Moore created what would become by far the foremost semiconductor maker in the world. They didn’t set out to create a billion dollar company or to transform an industry, but that is exactly what the pair did when they founded Intel in 1968. Though best known for its Pentium and Celeron microprocessors that can be found in more than three-quarters of the new PCs that come today, Intel also makes flash memories and embedded semiconductors. Now, with over $35 billion in revenue and annual growth standing at 13.5 percent, the legacy left by Noyce and Moore remains one of the strongest examples of innovation and entrepreneurship in the 21st century.

“It’s important to remember one thing that is essential for any entrepreneurial organization,” says Moore. “Do what you do well. Look at other things as incremental opportunities, but don’t change the basis of what you do well.” Moore and Noyce might have had many failed products over the years at Intel – arguably more than most successful companies – but they never strayed from their original idea as to what they wanted their company to be about. Indeed, it was by focusing on a single vision and doing that well that they increased their circle of influence and climbed to the top of the industry.

Today, Intel is ranked 49th on Fortune 500’s list of the top revenue grossing companies. Noyce and Moore may no longer be in charge of the daily running of the business they first founded in 1968; however, their impact on not only the company, but also the entire industry can still be felt. The maker of motherboard chipsets, network cards, flash memory drives, graphic chips, embedded processors and more, Intel is an innovator and a leader in the world of electronics and computing. How did two scientists who knew nothing about business become two of the most successful examples of entrepreneurship in history?

Hardware Technology

The oval shape above is a device. The device can be put under the water.  The use of that device is to draw anything underneath or on the water itself. When turning on the device, you can set the setting you want for your drawing choices. You may change the color setting and even after done your drawing, you can control how the drawing object move. For example if you draw a fish,  you may adjust how the fish swims or moving. Drawing doesn’t need any tool just our hand touching on the water.

Anything that contain water can use the device even if it is a glass of water, a container of water or a swimming pool. Below the device on the picture showing an example of a drawing of a lady in the swimming pool on a top view. Kind of  like a dream fantasy drawing.

Most of all, when turning of the light or in darker places, you may see the objects that you draw will be glowing in the dark.
