IT importance


IT is important for your business and this sounds like a ridiculous, perfectly obvious statement to make. Few people, however, take the time to think about the major role that informational technologies play for corporate development and operations. Every employee needs some familiarity with informational technologies. Such knowledge gives the company an edge over competitors that are still unfamiliar with new computer advances.

E-mail is the main form of corporate communication. For many, especially for companies that operate in multiple countries, e-mail has actually become more important than telephone calls. Instant messaging and computer chats are two additional forms of communication that have established a leading role in the corporate world.

Document processing, spreadsheet manipulations and the creation of presentations are other important IT skills that will determine the efficiency of corporate operations. Having to train employees or having employees that lack such skills will slow down the production process and decrease business efficiency.

Internet and technologies are becoming increasingly important for corporate operations. Many companies are already offering online services, selling products via their websites or using the online realm for marketing purposes. It is unbelievable to imagine a new business that lacks a website.

The world of computing and web is changing all the time. Trends that used to be fashionable several years ago are already outdated. Investing in the IT qualification of employees gives companies access to the newest advantages and characteristics of corporate communication and operations.

The fact that the world of computing has developed a lot over the past few years means that IT crime is also on the rise. Good IT policies and knowledge of the most successful practices minimizes some dangers connected to corporate information security breaches.

Proper IT practices will diminish the chance of becoming the victim of internet crime or experiencing a breakdown due to a virus. Such threats should never be underestimated because they can bring corporate operations to a halt.

Good company traditions in the realm of IT can ultimately increase the success of a company and the profit that it makes. Informational technologies are a part of nearly any business process and their proper utilization will determine whether your business ranks among market leaders or whether it experiences difficulties getting established and recognized as something innovative and highly modern.


Android & Mobile phone


The difference between A909.7Inch Android4.0.3IPS Screen
Tablet PC and mobile phone
My classmates have changed mobile phone; some also have the Android tablet computer, but me still in use several years ago to buy the phone. My phone Contrast to the touch screen phone, it is too bad. Every time I see them using a or Android computer, I am very jealous, and I feel very humble, I want to have very much.
Finally I got a little money, but when I have money, I do not know how to choose, which I can to choose? I will to buy a new phone, or to buy an Computer? This is a very annoying problem.
On the computer, I recently saw A90 9.7Inch Android4.0.3IPS Screen Tablet PC, I checked, I think this tablet computer, the price is very cheap, very convenient operation, but also to meet a variety of software. I like Android tablet computer, because the A90 9.7Inch Android4.0.3IPS Screen Tablet PC has a large screen, I watch a movie or browse the webpage can be more comfortable, fonts and images will show big.
Although the Android Computer and mobile phone function is almost the same, but the flat computer large volume, mobile phone is littler than Tablet Computer. also has Internet function and a variety of entertainment function, the same support for some games, but it only has a small screen, seems uncomfortable.

Finally, most of the people are in favor of me buy A909.7 Inch Android4.0.3IPS Screen Tablet PC. So I bought this Android Tablet computer.
But of course the portability can be reduced.

Cisco



  To stand in competition there is a need for an individual to have some professional certifications in his/her related field. Cisco provides certifications for people.In many workplace they always encourage junior network engineers to follow a Cisco certification path, either through the Routing and Switching path or other important technology paths such as network security and VoIP.  Getting your Cisco CCNA Certification is perfectly sufficient to start with; don't be pushed into attempting your CCNP. After gaining experience in the working environment, you will have a feel for if it's relevant for you to have this next level up. If so, your experience will serve as the background you need to master your CCNP - which is quite a hard qualification to acquire.

Most network administrators and engineers are going to spend a lot more time troubleshooting than installing. That's just the way it is. And to troubleshoot effectively, you've got to know what's going on at all layers of the OSI model, not just layers 2 and 3.

  Additionally, the only way to truly develop your troubleshooting abilities is to know what's going on over the entire network, not just the routers and switches. Troubleshooting always starts at Layer 1 if you don't find a problem at the Physical layer, and everything's fine with your routers and switches, how are you going to continue troubleshooting if you don't know what the next steps are as data moves closer to the end user?

There are several training options available for CCNA Exams preparation, such as self-study via books, instructor based training (boot camp style), video training, simulation exams etc. From my own experience when studying for my Cisco exams, and also from discussions with other certified colleagues, one of the best ways to study for CCNA is using a CCNA Training package. Especially when you combine a video training package with exam practice questions, you will have a complete preparation method for passing your exam. A video training package includes DVD quality videos with a real instructor teaching the course and guiding you through the exam objectives to help you pass.

Required Exam(s)

640-802 CCNA Interconnecting Cisco Networking Devices Part 1 (ICND1) v1.0

Interconnecting Cisco Networking Devices Part 2 (ICND2) v1.0

OR

640-822 ICND1 Interconnecting Cisco Networking Devices Part 1 (ICND1) v1.0

640-816 ICND2 Interconnecting Cisco Networking Devices Part 2 (ICND2) v1.0

CCNA aims at wide audience of professionals as well as students in the background of computer science and IT sector. Cisco CCNA is for those people who are basically engrossed towards acquiring technical information of networking and internet. This can aid in starting a good career in the industry of networking.

Certification program of CCNA and courses of CCNA is to enhance the professionals’ skills in the small and home office segment of networking. Certification of Cisco CCNA is an essential competency in networks of computer. Support and installation of 100 nodes or less than that in an environment of WAN/LAN is the examination of knowledge in this certification. It involves Internet protocol, Apple talk networks and Novel IPX.

Hard Drives


HDD's or Hard Drives usually refers to Hard Disk Drives. Hard disk drives play important role in a computer by storing all the informations of a user such as programs,documents,music etc.   A computer system must have at least one Hard Drive or may  have multiple drives. Hard drives have two positions in a computer system. A hard drive may be positioned  internaly that is inside the computer or may be positioned  externally that is  outside the computer. In a computer system, a hard drive is the slowest part from all the parts of system. The size of a hard drive is measured in Gigabytes (GB).
Types of Hard Drives
Many types of hard disk drives are available today but the main types are few which are differentiate from each other according to their technological structure.

  1)_ SCSI - These hard drives are the fastest hard drives uptill now. They are basically used in servers. SCSI are used in places where only the  best reliability is needed. SCSI drives are highly expensive. Their speeds reach up to 320 MB/s.

  2)_  SATA - SATA is a new era technology. SATA drives are becoming the standard for desktop computers. Their speeds reaches up to 375 MB/s. Because, SATA technology is latest therefore it can not work on older computers. A convertor card is used to use SATA technology in older computers. A  SATA  drive can be used either as internal and external drives depending upon the  requirements of computer system. A computer may use internal SATA drive or may use external SATA drive.

  3)_  IDE or PATA - This technology is in use for many years. Most  systems of the last 15 years suppors this technology. PATA and IDE both refers to the same technology. Infact this technology is the replacement of the SATA. IDE hard drives reaches up to speeds of 133MB/s.

 4)_   USB/ Fire wire - These technologies are used as external hard drives. USB2 is commonly used connection for an external hard drive. External hard drives generally slower than the internal hard drives. The max speed of Fire wire hard  drives reaches up to 60MB/s.

 Spin Speed 
        Besides the type of hard drives, the spin speed of hard drive also matters. The spin speed may vary from as slow as 4800 rpm  to 15000 rpm. RPM is the ‘rotation per minute’. Usually the speed is measure in rpm. Slow spin speed as 4800 rpm is used in laptops and  high spin speed as 15000 rpm is used in SCSI drives. The average spin speed of hard drive  is 7200 rpm..

Cache Size
           Cache size is also an important factor  in hard drives. Usually, the hard drives have a cache of between 8MB to 16MB. The cache is a place where the data is temporarily stored before it is written to the hard disk. The cache is much faster than the drive itself.

      Internal and external hard drives are manufactured by many manufacturers. The popular manufactures for hard drives are Maxtor, Western Digital, Seagate, IBM, FreeCom and LaCie.
