however, information technology and computer jobs that require significantly less schooling. Individuals are employed as network administrators; technical support professionals; and computer repair technicians — and often, they are eligible for this sort of employment after just several months of study. This 70-290 article will discuss some types of quick-study computer education and career training programs that lead to professional certification — and often, directly to technology careers.
The A+ certification is designed to prove a student’s abilities as a general computer technician. A+-certified technicians understand computer systems inside and out. They are as comfortable working with hardware (the “guts” of the computer) as they are with operating systems, software, networks, and files. They have the ability to troubleshoot computer problems and to achieve resolutions to those problems with 70-291.
The Security 5 certification is established and administered by the International Council of E-Commerce Consultants. This organization considers it to be an entry-level security certification. Nonetheless, it is recommended that students or network administration career professionals possess the equivalent knowledge of A+ and Network + exam material if they wish to seek careers in network security.
This exam covers a variety of network and desktop security principles. Students will need to have a solid foundation of basic computer security concepts, like firewalls and hack-proof log-ins. They will also need to understand computer cryptography, e-mail and communications security, secure site and Web browser procedures, and file transfer/FTP security. Desktop and hard drive security, portable and wireless security, and secure computing with third-party devices are additional topics covered.
This exam, when combined with another professional certification or prior networking and information systems experience, can be a powerful career asset. For those computer users who are not employed in the networking or information sciences sectors, the Security 5 certification can be a great asset in protecting the privacy and integrity of personal data.
The Microsoft Certified Desktop Support Technician (MCDST) certification is specific to information technology applications in the Windows desktop environment and Windows operating system. It is considered to be a beginner-level credential, and it demonstrates that an individual is competent in assisting end users and helping to test and troubleshoot Microsoft desktops and applications. This Microsoft certificate can be completed in tandem with other certifications supported by Microsoft, including the Microsoft Office Specialist (MOS) certification and the Microsoft Certified Database Administrator (MCDA).
Currently, professional Windows environments are in a transitory phase between Windows XP Professional and Windows Vista. Vista’s large allocated operating memory requirements and compatibility difficulties have caused XP to remain widely used in the workplace — so there are some career environments in which the MCDST, MOS, MCDA, and other certifications are necessary. Network administration specialists and information sciences students should be aware, however, that Microsoft is changing the certification requirements in accordance with the new Vista user interface and desktop functions.
