Definition Of Computer Hardware

A computer device is made up of two major parts; Hardware and Software.
Hardware is the physical components of a computer like a monitor or the mouse, which you can actually touch. Computer Software are programs or applications that give instruction to hardware on what to do, and can not be physically touched. The best way to think about this concept, is to picture a human body, all physical parts such as arms, legs, heart, eyes, etc are the Hardware and the synapses made by the brain that send information to the rest of the body would be the Software.

The following are examples the hardware of our modern day computers:
-Monitor
-Motherboard
-CPU
-RAM Memory
-Expansion card
-Power supply
-Optical disk drive
-Hard Disk
-Keyboard
-Mouse

The Monitor is usually known as the computer screen and displays what is being processed and accessed.

The Motherboard holds the major components of the computer system and provides connectors to peripherals (keyboard, mouse). It is also known as the system, main or logic board.

The CPU carries out the instructions of programs and other computer functions.

The RAM (random-access memory) is the way to store data on a computer on circuits that can be accessed in any order. Types of RAM; ROM and some flash memory.

The Expansion card is a circuit board that is inserted into the expansion slot of the mother board and adds functionality or even memory to a computer system.

The Power Supply provides the power or electricity to the computer.

The Optical Disk Drive is where you insert you CD or DVD into the computer.

It uses a laser or waves to read or write information to and from the disk.

The Hard Disk stores data that is encoded digitally.

The Keyboard is the device used to input information and commands into the computer system. It resembles a typewriters keyboard.

The mouse is the device used to point to items on the screen.

There are many parts that make up a computer and there is no better way than e-learninge-learning to learn how to use the integration of both computer hardware and software. When the convenience of learning from home or the location of your choice is the only option, the best way to go is e-learning.

Best Internet Tv Software For Your Laptop Or Pc

What’s the very best Internet TV Software? I won’t tell a lie… I travel a lot and usually have my laptop with me for either work or pleasure. In April, whilst in Vegas at a WSOP circuit tournament, and back at my hotel room, I just didn’t feel like watching your regular programming on US TV. Boring, boring! And I certain didn’t feel like working.

So out came the laptop to check my emails, one of which was for Internet TV Software program. “Why not”, I said. It was of those having a one-time payment… not 1 of those where you had to pay a monthly fee. Well, it was the best purchase I’ve ever made. There I was watching uncensored Web TV, including adult stuff, from over the world. Not just that… I had good music also. Best component is… I got to test drive it for totally free.

Of course the software didn’t consist of paid channels like Showtime, but who cares because they always run the same movies over and over once more. I had a bunch of programs from all over the world that I didn’t even know existed. It’s an awesome tool allowing me to watch free media 24/7 via any web connection a your hotel/motel.

Downloading one of these is probably one of the very best purchases I’ve ever produced for my computer. I had instant access to over 3000 of totally free channels with fantastic content, and completely uncensored. Get what I mean. I never thought Internet TV Software could be this great. You are able to turn your home or work PC into a Global Entertainment Center.

From the privacy of your laptop or PC you are able to watch news channels from all over the world. Watch soccer along with additional sports programming from Mexico, Ireland, France, and SEXY programming from Europe. You will not think how much selection there is within the channels. See what you are astutely missing!

In the event you wish to learn much more about this Internet TV Software, I extremely suggest you think about visiting: Web TV Software program.

Hardware Virtualization Support In Modern Cpus

To avoid the issues surrounding the non-trappable privileged instructions, CPU manufacturers have added virtualization capabilities to modern CPUs. These CPUs still need to behave exactly like their older counterparts, to ensure backward-compatibility with existing applications, so the behavior of the non-trappable privileged instructions is identical on these newer units. However, a new set of instructions, which were not previously available, provides for a special virtual machine mode of operation. This mode provides extra levels of I/O and memory protection, and allows the special instructions to be detected and handled externally by the CPU in conjunction with a suitably written hyper visor VMM.

The first revision of this instruction set provided basic support for virtualizing the non-trappable privileged instructions, and the supporting instructions required to interface the hardware support to VMMs written to make use of it.

CPUs with first generation hardware virtualization support are not capable of nesting VMMs in a way that allows the nested VMM to also take advantage of the hardware virtualization capabilities. This means that when using CPUs with first generation hardware virtualization, only the outermost VMM can benefit from the hardware acceleration. While this may not initially seem to be a problem, some modes of operation are not possible without hardware virtualization support, meaning those modes will not be available in a nested-VMM configuration.

Furthermore, some computer manufacturers intentionally disable hardware virtualization support in their PCs, even if the hardware is capable of supporting it.6 The second revision of this hardware support, present in only the newest CPUs at the time of this writing, does allow virtualization of the hardware virtualization instructions, allowing for some degree of nested VMM capabilities.

Limitations and Challenges

Performance There will always be some level of performance overhead associated with hyper visor VMMs. As CPUs evolve to include more hardware support for virtualization, the areas of performance impact will shift from the VMM to the emulated hardware instead, which can still result in a non-trivial impact.

VM inside another VM As mentioned before, unless one uses extremely new hardware it is not possible to run a hardware-accelerated VM inside another hardware-accelerated VM.

No hardware assist Especially important in a virtual desktop solution, one must consider the millions of PCs in the field that could be used as host PCs that do not have even the first generation of virtualization support.7

Hardware Keylogger – Helping You To Monitor PC Users Without Being Detected

Sue has been the most commited employee. She is always at her duty post doing what she was being paid to do. With all the zeal and industry being exhibited by Sue and most of her colleagues, the company couldn’t explain why productivity was taking a steady and speedy decline until a consultant detective was hired.

Investigations revealed that Sue spends 70% of her -work’ sessions in dating chat rooms. Other times, she was emailing her pals and reading internet news – oh she loved the -fashion and style’ segments!

Worse case for Steve who was discovered to be trading the company’s sensitive information’s to a rival group.

How were these discoveries made since these people work alone in their closets and never share their computers?

Hardware keyloggers to the rescue!

keylogger are devices that are used to monitor the activities on a computer. It works by tracking the keystrokes, recording conversations, tracking the creation of documents and monitoring emails. This is usually achieved when a hardware circuit is attached somewhere in between the computer keyboard and the computer. They are designed in such a way that they blend with the rest of the computer cabling.

How they work

They basically interrupt the keystrokes signals and stores them away. The storage can range from 2MB, which is enough for one – week use, and up to 2GB of flash memory. Ideally, these memories can only be accessed by the individual that installed the device.

To access these memories the installer presses a combination of keys which switches the device from a keystroke-capturing mode to a usb flashdrive mode. Then you receive a message which tells you that a new usb disc drive has been located, and there you will find the keystroke logs that were collected. You also see a configuration file which you can modify in order to change the secret access key.

Hardware Keylogger are now preferred to software keyloggers. The latter can be easily detected by software scanners, and their operations are limited to a single computer. They are also dedicated to only one type of operating system which could be Windows, Mac OS, Linux, etc unlike the hardware equivalents which are operating system – independent, and whose operations, recording and playback, can be done on two different computers. One other minus for the software type is that it requires full access to the operating system to be installed, when the installer might only want to sneak it up and catch the target users off guard.

So for parents who want to track their child’s PC activities or employers who want to monitor their workers or generally for computer users who want to back up typed texts, monitor remote computers, retrieve unknown passwords without depending on the operating system, hardware keyloggers provide the perfect answer.

Precautionary Action Plan Of Hardware Failure In High Availability Database Servers

Hardware failures pertain to failures experienced by different component such as disks, controllers, CPUs, memory, routers, gateways, cables, tape drives, fans, and so on. Such failures generally call for the malfunctioning component to be repaired or replaced. Once thats done, regular operations can be restarted. It is important to maintain multiple components for those susceptible to frequent failures. Single points of failures are common causes of high downtime. For instance, twin-tailed disks that connected across two nodes or mirrored disks allow systems to remain functional even when a node or mirror goes down in the case of a node going down, there may be a brief disruption, again depending on the fail-over solution implemented.

If just a single component is maintained, during the time it is being repaired or replaced in the repair window, service will be unavailable. Sometimes, the time required to obtain a component can be horrendously long. For example, when we blew a disk controller at a client site, the hardware engineers determined that the component needed to be totally replaced. It was not available locally and had to be flown in from out of state, taking at least two days to get in and be replaced. Situations like these can cause tremendous downtime.

There is a chance of failure of hard disk or disk controllers too. Important thing is that, we cant able to judge this kind of hardware failure. But for precautionary action plan, we need backup server in high availability database server environment. If backup server is not possible in every cases then we need to make strong Service Level Agreement SLA with strict condition and response time with hardware vendors. Sometime we need to put some penalty clause too in response time measurement of replacement and availability of failure component. Using this trick we are able to maintain lowest downtime for high availability database servers.

A two-day service interruption may cause a company to out of business in certain cases. To avoid situations like these, some of my clients have a component availability guarantee clause put in all hardware contracts, wherein the vendor would ensure that specific components prone to failure would be available locally or obtained within an acceptable predetermined time period from specific remote sources for immediate replacement. Identify all critical components are augment them with clones.

Additionally, all hardware should be maintained securely inside cabinets to prevent accidental or intentional damage. All guidelines from the manufacturer temperature, proximity to other devices, and so on should be strictly followed. Cabling should be done as neatly as possible, so as not to get in the way of people walking about. Raised floors in your data centers greatly help in preventing accidents.

Singing Lessons Software – Don’t Bang Your Head!

There are some good beginner singing lessons software programs out there if you look in the right places. Some programs don’t live up to their hype. I stick with the ones, which have a long established track record.

Just like anything, I always make sure to seek others, who have used something before I consider buying it. There are a couple of good learn singing guides you can download now, which eliminate the need for expensive vocal coaches. For me, singing lessons got expensive and I felt like I didn’t need them anymore to just review what we already learned.

With a decent beginner singing lessons software program, you don’t have to learn something one week with a teacher and then pay them again to review your progress and go over the same stuff.

I can usually hear my own progress as a singer or I can record myself to hear the progress. With a decent instruction program, they will have recording software and ways to play back what you just practiced into the mic. There are also ways to improve with singing games, which come with some programs. This might suit some aspiring singers more than hiring expensive vocal coaches.

Don’t get me wrong, some vocal coaches are absolutely fantastic, but who can afford them on a weekly basis? I sure couldn’t as an aspiring musician with a decent pay check coming from my day job. That’s why some teachers will even tell you they’re finished with you after you have four or five lessons. This is admirable when teachers do this because they could keep trying to milk you for more money.

So there are a few good programs out there just find which one has the best reputation and which one is created by someone well knows in singing circles. That way, you are less likely to be disappointed with the beginner singing lessons software that you decide to acquire.
