Functions of Device Drivers For the Hardware and Software Components

techno11

However, device drivers are coded differently for conforming to the requests of the application and the features of the hardware component. >

Device drivers act as programs tasked to translate application or user requests into a form comprehensible to the hardware. Despite the diversity of features coded directly into an application, it does not contain the necessary procedures that can allow it to directly relay its requests to a hardware device.

They are programmed to receive related software requests for using the features and functions of the corresponding hardware device. These requests usually take the form of high-level codes from a programming language used in the creation of the software.

Device drivers subsequently convert such related application or user requests into machine language or codes comprehensible to the hardware component after it receives the requests. The result would be the implementation by the hardware device of the related application or user requests.

A programming language called Assembly has the capability to directly tap into the functionality of a device. However, it is not compatible with the design and complexity required by user’s for high-end applications.

A simple example of such device driver activity is when a user tries to view a music file using a third-party application such as Windows Media Player. The media application then relays the user’s instructions to the sound device through the use of the audio device driver. The user can subsequently view the audio data contained in the music file through the speakers or headphones attached to the sound card of the machine.

Hardware devices also require the capability of device drivers to provide users with the ability to directly manipulate its functionality. Aside from using a third-party program to achieve this, a user may change the settings and configurations of a hardware device using its respective drivers. This is usually the case of display and sound devices installed in the computer.

However, the correct device drivers need to be installed before a related application or a user can manipulate a hardware device and use its bundled functions or features. One should always consider these factors when installing the correct drivers for a particular hardware device: the version of the operating system used; manufacturer of the device and the model or make of the hardware component.

Software Reviews

techno2

Nowadays almost all information is kept in the electronic form. There are numerous advantages of such evolution: spare place on your shelves and in the house, as a whole, quick and categorized access to each topic, great visual design and interactive interface of most applications which are used for data storage and general computer functioning. Most of us buy additional memories, hard drives and other devices in order to download films, games, keep personal photos and videos and install large and consuming software. It is obvious that all modern information is taken from the world`s network – Internet. It is a massive storage of all information indeed. I think that there hardly exists a book or a magazine which has not yet been converted into the electronic form. Thus, it is obvious that we would like to protect such data from sudden delete, from being infected by spy viruses or stolen from our private machines. That`s why antiviruses have become one of the most frequently downloadable software. But together with safety they have brought some negative outcomes. For example, well-known McAfee protection system is one of the most complained one when it is time to apply to the software reviews. It is obvious that paid services are more reliable than the free ones. But don`t start to make conclusions because together with offered bonuses you can get unauthorized charges from your account, low level customer service, slow operation power, etc. -I had checked my account and it appeared they had not stored mycredit card info: As I was about three weeks out before the term expired I thought I was good to go/. I planned on letting the account expire?. They then charged my account for a years worth of service (15 days before the end of my current term).- – proves my words one of the McAfee`s, I guess, ex-clients. Moreover, software reviews highlight the activities of such companies as Iolo Technologies, Rainsoft, Intuit, Microsoft, WaebWatcher and many others. They provide a wide range of services and very often differentiate from just software supply to the supply of appliances, supportive instruments, etc. The already mentioned computer giant Microsoft and well-known companies like Intuit are, unfortunately, leading the list of the most complained one when it comes time to mention negative opinions from the software reviews. How to deal with the negative issues and outcome? Specialists recommend to purchase the software from the official representatives and check such details as serial number, holographic sign, description, etc. As for the warranty, it is also foreseen for the reliable software. You should keep all the documents and checks which submit your purchase and be ready to show them in case of any troubles. Also, be careful with the online purchase of the software because fraud issues are very often to take place on such resources which offer immediate download.

Define Computer Hardware

techno4

It is quite well known that the working of the computer is pulled by hardware and software. One can define computer hardware as the electronic, magnetic, and electric devices that carry out the computing functions. Hardware is the physical components of the computer like microprocessor, hard disks, RAM, and motherboard. The peripheral devices such as monitor, mouse, keyboard, printer, and speakers can also be included in the list of hardware parts. The programs that run on the computers like Windows, C++, and Photoshop are the software parts of the computer. A good example for an easy understanding of hardware-software definition is music CDs. The actual compact disk is the hardware, while the songs and music in the CD are the software parts.

There is another way to define computer hardware. Hardware devices are the executors of the commands provided by software applications. For example, let us see what happens when you click the print button of the web browsing software. The software application provides a command to the processor, which is the central part of all computer hardware. Processor in turn checks for an attached printer. If the printer is ready, the software will get a positive response from the processor. Then the software application provides instruction to the printer via the processor to print the web page. In that sense, hardware parts are the foot soldiers and software applications are the commanders in the digital operation that takes place within a computer.

The main player of computer hardware is undoubtedly the microprocessor. It is the sun in the solar system of computer hardware devices. It is the central component and all other components work around it. It is an integrated chip on which a number of functions are incorporated. Two specifications determine its efficiency. One is its processing speed, which is measured in gigahertz. The other is its bit rate. Commonly available processors are 32 bit and 64 bit. The bit rate is a measure of the efficiency of a processor to carry out multiple operations at the same time.

One cannot define computer hardware without mentioning the two types of memory used in computers. One is permanent memory. It refers to the magnetic storage capacity of hard disk. It is measured in gigabytes. The second is RAM or random access memory. This memory is able to store data only when the computer is switched on. The memory will lose all the data when the computer is switched off.

Another important product that one should mention when one defines computer hardware is motherboard. It is the electric and electronic circuit board on which all the other components are inserted. There are several other kinds of products such as sound card, video card, network card, and modem that complete the hardware spectrum.

It Consultants Don’t Skimp On Hardware With Power Users

techno8

As IT consultants, whatever you do, don’t let your clients skimp on PC purchases for power users who run high-end software.

While many of your small business clients employees depend mainly on software with modest hardware requirements, such as basic word processing, spreadsheet, e-mail and Web browsing software, there are certainly exceptions. Make sure you know who your clients power users are.

Power Users Need Cutting Edge Technology

If you have clients that depend on an advanced software application, such as graphic design, computer assisted design (CAD) or financial modeling, as IT consultants, you may want to advise your clients to implicitly “eat” that sky-high first years depreciation on the purchase of the latest and greatest PC hardware.

With processor and memory-intensive software applications, the employee productivity your clients will gain with leading-edge PC hardware likely will offset any major depreciation cost concerns.

Keep In Mind The Users’ Salary

Consider the salary required to attract and retain highly technical professionals who run advanced software applications. (As IT consultants, this high-salary-requirement-reality should come as no surprise.)

For example, if a clients of yours has a veteran graphic design artist or engineer on payroll at a $60,000 base salary, an extra $1,000 a year on PC-related expenses for this technical wizard easily could drive a productivity gain that makes the incremental expense seem trivial.

Get To Know Your Users

The moral of story: get to know your clients power users and their specific software applications needs. Just as important, clients power users are a kind of influencer that you need to be very aware of. Your clients power users are often very powerful votes when it comes to making decisions about hiring (and firing) IT consultants.

IT Consultants Should Consider “Hand Me Downs”

In many small businesses, the premium performance PC purchased for the power user gets replaced every year or two, and is passed down to an end user with less demanding software requirements. This is one way to extend the life of an expensive, high-end PC, while minimizing the out-of-pocket and related support expenses of bringing new PC hardware into your company.

Make sure your computer support, asset management and proactive maintenance plans all take this hand-me-down phenomenon into account.
