Importance of Computer Accessories

Computers have become really advanced with wide varieties of accessories attached to it. We can define an accessory as a device which is attached to a computer but is not a part of it. The functionality of an accessory depends on the computer it is attached to. A computer has to be equipped with all the necessary accessories in order to carry out all the tasks in more efficient way. There are two forms of accessories one is basic accessories and other is an advanced accessories.Basic accessories available are speakers, printers, scanners, UPS, surge protector, headsets, cases and covers,cleaning and repair kits etc. Advance computer accessories include webcam, microphones, gaming equipments, portable storage devices, CD and DVD recordable drives, network accessories, modem.

These computer accessories make each task very fast and easy for example if you have a personal printer connected to your PC then there is no need to go to any office to get the document printed. The most important computer device is the UPS (Uninterrupted Power Supply), it provides a continuous power supply to a computer so that no data should be lost. A Headset comes with a built-in microphone so you can not only listen to music but also make a call from your computer to other computer or phone. Webcam allows taking pictures or recording your video or can be used to have a live chat with anyone through internet.

Portable storage devices like USB flash drives can be used to transfer data. The capacity of these devices varies from 8 to 12 Gigabytes. Rewritable CDs and DVDs are also other source of transferring and storing data. If above devices are not enough for transferring data then we can also go for networking accessories such as LAN cables or modem. These networking devices can be used to transfer data within a Local Area Network or over internet.

Most of the laptops have built-in wireless internet which enables the traveler to access the internet while traveling. Important features of the mini laptops are the external monitor support and S video used to connect it to TV. A wireless laptop mouse is a great accessory. A desktop computer also comes in amazing all-in -one features which includes touch screen, Wi-Fi, color choices, built-in webcams, and TV tuners.

In order to buy a new desktop computer one needs to know that there are standard accessories which comes with the computer like speaker, keyboard, mouse, monitor. But there are some which has to be purchased separately like webcams, UPS, modem, external hard disk etc. But in case of a laptop, webcam, speakers etc comes as built-in devices. Other devices to be purchased are portable laptop desks to prevent laptop burn and provide comfortable working position. Universal Laptop power adapters, portable projector, mobile printers, wireless laptop mice, laptop speakers are some of the other computer accessories to be purchased while buying a laptop.

Most Common Ways to Accumulate Spyware (where It is Downloaded to Your PC)

It is possible that if one avoided all sources of spyware, ad-ware and virus infection that infection would be at minimal levels. Although I don’t recommend using only this method as a form of fighting spyware, it can be a potentially effective mean. Used in conjunction with a virus scanning program (I recommend Avast), abstaining from visiting these web sites or using these programs will help your PC to fight off infections, infestations and slower speeds due to unneeded running processes.

The most common places where your PC will pick up spyware, ad-ware and viruses will be adult websites or websites related to security. By security, I mean websites related to computer hacking and the like. If you partake in software piracy, you will notice that many of these websites that are piracy download zones have javascripts and cookies running that download software to your computer unknowingly. They usually come in the form of cookies. If you run a good virus program while you visit these sites, your virus program will most certainly warn you to “abort the connection” or “terminate the script.” This means a server-side script is running to put spyware in the form of cookies onto your hard drive.

Another good spot to accumulate spyware, especially trojans, is peer to peer file sharing software. Such programs like Bearshare, ARES, Kazaa, etc. have been known to be breeding grounds for trojan horses and keyloggers for sometime. I recommend if you decide to use these programs, you use the “lite” version of the program. Lite versions of said programs have been scaled down in memory usage and the like. They will still operate just as well as the full program, but your computer will like you better for not subjecting it to unknown dangers.

And alas, the final spot of interest would be chain mail letters with attachments. These annoying buggers are usually sent to you by friends with too much time on their hands. Some people become addicted to chain mail letters; they send out every single one they receive. These letters sometimes can have viruses in their attachments, but because the average computer user does not realize it, he or she is spreading a virus. ALSO NOTE: Chain mail letters have been known to connect pedophiles with their prey. This is because the person who receives the letter can trace it back to every single person who has read it. Notice a chain mail letter has tens, maybe hundreds of e-mail addresses upon it, and sometimes these belong to young people (as young people make up a large portion of Internet users). Use a virus scanning program that checks your incoming mail (Avast will do this), and use something like NetNanny to make sure your kids have no strange men or women talking to them on MSN messenger.

IT Job Titles – What Do They Mean?

Although only a few decades old, the information technology or IT field is as broad and deep as industries that have been around for centuries. IT job categories, titles and specialties abound – so many that anyone investigating IT as a career is likely to be very, very confused. What’s the difference between a Network Engineer and a Network Support Analyst? Between a Web Developer, a Web Designer and a Web Technology Specialist? Just what does a Database Administrator do?

Although labels and responsibilities tend to vary from employer to employer, here are some common IT job titles and their descriptions. Consider these when looking for an IT career that best suits your interests, talents and temperament:

Database Administrator – A database is any collection of information that a company or organization keeps on file (e.g. customer names, addresses, inventory, etc.) The Database Administrator (DBA) is in charge of organizing, maintaining and updating this database and creating systems so that people authorized to view, add or remove information are able to do so as quickly and as easily as possible.

Internet Solutions Developer – This is a “catch-all” description for a person responsible for devising and executing Internet-based projects. The job usually involves working with programs that allow the public to view and interact with a company, organization or agency’s Website.

IT Project Program Manager – This is a managerial position requiring some years of experience in the IT field. The IT Project Program Manager is responsible for finding solutions to IT-related problems and then implementing those solutions, often with the help of a team.

Network Administrator – A “network” is any collection of computers that are linked either to each other or to a central server so that information can be created, shared and updated. The Network Administrator is generally responsible for making sure than an existing network runs smoothly and for adding or removing hardware (computers, printers, etc.) and software (programs, applications) from the system.

Network and Security Specialist – The Network and Internet Security Specialist is the person responsible for making sure people who use a computer network only get access to that information they are allowed to see, that information in the network database’s is protected and properly preserved, and that the network cannot be accessed (or “hacked”) by unauthorized individuals, wherever they may be.

Network Engineer – The network engineer is usually responsible for 1) Designing new computer networks, 2) Actually creating these networks, 3) Installing the computers and software that connect to the networks and, 4) Ensuring the network is able to grow and function as needed.

Network Support Analyst – A Network Support Analyst is much like a Network Administrator in that he/she is responsible for keeping an existing network operating as needed, but has fewer managerial responsibilities. The Network Support Analyst may also be responsible for monitoring how people actually use the network, identifying problem areas and then recommending and implementing solutions.

Software Developer/Engineer – “Software” is the set of instructions that make a computer do what you want it to do. The Software Developer/Engineer is the person who writes the instructions, also known as “code,” for these computer programs/applications. Software Developer/Engineers may work “in-house” developing customized programs for a specific employer or client, or may work on programs that are then sold commercially.

Technical Support Specialist – Computers and networks invariably have problems, and it’s the Technical Support Specialist’s job to identify these problems and find a way to correct them. Technical Support Specialists often work at “help desks” where they communicate with company employees or customers by phone, IM or email.

Web Developer – Web Developers create, maintain and update the functional aspects of Websites, be they on the Internet or on a company’s internal Intranet. When designing a new site, they’re usually responsible for creating its architecture, navigation and interactive functions. They may also be responsible for creating programs or applications designed specifically for the Web.

Web Designer – While the Web Developer is concerned with the technical aspects of a Website or Web-based application, the Web Designer is responsible for how such a site or application actually looks. This is an artistic position that requires training and experience in graphic design and layout – and perhaps even animation — as well as the technical aspects of Web operations.

Web Technology Specialist – This position combines the responsibilities of the Web Developer and Web Designer. The Web Technology Specialist needs to not only the technical aspects of Websites and applications, but also needs to frequently handle the design and graphic aspects as well.

If you are considering career training in Information Technology, you need to understand these (and other) job descriptions so you can pursue the education and training that will qualify you for the kind of IT job that fits your talent and personality.
