What’s New in the A+ Exams, Part I: Core Hardware
Objectively in accordance with objective guidance to A + in the near future, and how they might affect your learning strategy.
from faithe text Peng November 19, 2003 - on November 26, the new version (CompTIA is a + The examination will be to live. these versions 2003 is based on a new target, as some technical changes we have seen, since the industrial Updated in 2001, which include not only the latest hardware (up to the P4), but also the latest version of Windows (as to Windows XP). a complete list of new goals and their topics, Click here.
One of the biggest changes I have noticed that in the new target is a better and more clear wording, making it easier to come up with different ways with a goal from another.
several goals also to be split into two parts (or three), so that each goal more specific issues, for example, in a couples circumstances portable computers be separated out from the desktop.
in this two-part article, I will provide an objective, in accordance with the objective of the report how to change what it means, I + students.
core hardware: Target 1.1 determine the names, the purpose and characteristics of the system modules. recognize these modules visual or definition.
the wording of this goal there are some minor changes, but it still has the same goals.
last words: 1.1 the basic terms, concepts and functions of the systems modules, including how to make each module of work, which should be in normal operation, and In "br> boot process.
new main topics are adapter, case, and riser card.
core hardware: Target 1.2 identified basic procedures for adding and removing field replacement modules for desktop systems. due to the replacement of the circumstances, the selection of appropriate sequence.
main difference between them is that the desktop and portable systems have been split into separate goals. goal of 1.2, now only refers to computers, desktop computers, and the new target of 1.3 also has been the same portable system. original wording : 1.2 the basic procedures for adding and the deletion of field replaceable module desktop and portable systems.
many of the themes for this purpose is the same as the title of the listing 1.1 goals, but they are approaching the point of view, accession and eliminate them here, not because they know very well that they specifications.
the topic of storage equipment has been made more specific, in the list of topics, clarify that, on this issue, rather than FDD and the hard drive, and standards and write CD and DVD and tape storage.
a cooling system has been increased, as a brand-new subject for the realization of this goal, including traditional media and liquid cooling systems.
core hardware: Target 1.3 the basic procedures for adding and removing field replacement module portable system. due to the replacement of the circumstances, the selection of appropriate sequence.
This is almost the same as 1.2 except goals, it applies to portable systems.
have equal before the goal. almost every subject, in this goal is technically the "new" because the target itself is a new problem, but many of them existed before the old Target 1.2.
new target appears to be joined expectation that an A + technician dismantling portable computers will be to remove the floppy and CD-ROM drives, however, because of the proprietary nature of portable computers, but every point disassembles different, we do not have too many A + exam can "test" on specific practices. some modular mobile computer diskettes and CD-ROMs Driver free swap out with other components others have built their hard system, and enable the dismantling of the need to be replaced. best views, and here is the "Reading service manuals." wireless network components are also added: Here, at client computers (also known as NIC). routers and other networking components cover other areas.
core hardware: Target 1.4 identify typical. IRQs, dmas and I / O addresses and procedures, altering When these settings, the installation and configuration of equipment. select the appropriate installation or configuration steps, in a specific situation.
formerly the 1.3 target, this one little change, in addition to its wording.
past worded as follows: identify available. IRQs, dmas, and I / O addresses and procedures for installation installation and configuration.
address this objective in terms of hardware, and its system resources. since almost all of the hardware use the same type of resources (. IRQs, DMA channel input / output address, and memory addresses), this is a simple matter. main task is rote default tasks of the common types of hardware. must first know transfer of all equipment out on the objective list of topics, such as the default IRQ for floppy disk control , as an example. infrared, and compatible with IEEE 1394, and USB no preset tasks, so for them, but they know the resources needed, for example, a USB root hub necessary resources.
individual USB devices but do not have such a requirement. an unexpected addition: specialized devices (For example: CAD / CAM technology).
core hardware: Target 1.5 identify the name, purpose, performance and features, standardization / common peripheral ports, the relevant cabling, and their joint recognition of the port, cabling and connectors, and so on, at a glance.
predecessor for the 1.4 target, but so far there has been little change, in addition to writing. that stressed that the wording of the new port vision recognition, that is likely to be take photographs to identify the pilot.
identify common peripheral ports, the relevant cabling, and their joints.
port here is the solution to this goal standpoint of identifying describe their ad hoc. its installation and troubleshooting, is not included in here These are the other goals . infrared has been added, and centronics has been divided into mini and 36. same sequence has been divided into NULL straight-through processing and modem .
core hardware: Target 1.6 1.6 to determine the appropriate procedures for the installation and configuration of common IDE devices.
the selection of appropriate installation or configuration sequence, in a specific situation.
recognize relevant cables.
formerly the 1.5 target, this goal has become more specific, but as a whole is the same. original wording is: to determine the appropriate procedures to install and configure the IDE / Eide devices.
listing subject to this goal is much more specific than they previously identified in the objectives, and add some of the topics such as the IDE RAID was not specified before it also outbreak of IDE type, Eide ATA / ATAPI and Serial ATA.
core hardware: Target 1.7 to determine the appropriate procedures for installation and configuration of the SCSI common devices. select the appropriate installation or configuration sequence, in particular scenarios. recognition Related cable.
formerly the 1.6 target, the target has become more concrete and its topics covered deeper understanding of the subject. original objectives are: determine the appropriate procedures for the installation and configuration of SCSI devices.
topic is much more specific, in this revised purpose, despite The magnitude of these problems was implicitly included in the earlier version. link "br> more expectations now, you will know the the differences between the numerous version of the SCSI and how they are compatible or not. expectations be asked whether the SCSI cable, including the length and type of , and termination provisions.
SCSI RAID is also the explicit reference prepared distinction between air raids 0, 1, 5 types.
core hardware: Target 1.8 determine the appropriate procedures for installation and configuration of common peripherals device. select the appropriate installation or configuration sequence, In particular scenarios.
formerly the 1.7 target, the target is more specific, but basically unchanged. original reads: determine the appropriate procedures for the installation and configuration of peripherals device.
many examples of this goal difference from the earlier version , and some issues have been removed, for example, reported a portable peripherals no longer belong here. Therefore, you should study the topic list this one carefully. new topics, including all types of Internet Link Line Device (dial-up, cable, DSL, ISDN network), digital cameras, PDA, wireless access points, printers, and UPS and repression.
core hardware: Target 1.9 identification procedures, in order to optimize personal computer business, in certain special situations.
forecast the impact of specific procedures, because scenarios.
this goal is formerly known as 1.8, which involves the procedures, and enhance system performance The original wording is: hardware identification methods improve system performance, procedures replacement component of the basic subsystems, unique components and when to use them .
the topics covered here is that the projects have been added or upgraded system Whether to solve a particular problem or to improve its performance. many of these are new to this amendment, including liquid cooling systems, RAID controllers cards and additional processors.
core hardware: Objective 1.10 identify problems, we must consider upgrading a PC. In "br > a particular circumstances, decide when and how to upgrade system components.
This is a new target, although some of its contents from earlier current goals. you should know how each of the other components affected When another component of the upgrade. this is a good example of the objective of the one-way word has been improved, and these are the necessary skills a technician said that the list has never been before.
core Hardware: 2.1 objective understanding of common problems with each of the modules and their symptoms are, and identify steps to isolate and Problems . since it is a problem situation and explain symptoms and infer the most likely reason.
Most of this target is still the same, but the wording of the new changes, including: Interpretation infer a cause symptoms. original wording is: identify common symptoms and related problems, each module, and , how to isolate and resolve problems.
this goal produced a huge list of topics that it covers, both desktop and notebook computers.
Many of these issues are also covered elsewhere, but here, we are talking about specialized problems and troubleshooting. some new things with the IEEE 1394 and infrared troubleshooting, mobile storage, and portable liquid cooling unique storage, and writeable CD and DVD.
core Hardware: Target 2.2 determine basic troubleshooting procedures and tools, as well as how to win symptoms of the problem, from customers. reason to question , especially in a scenarios.
this goal is still mostly the same, a simple increase added, which involves On strategy with customers and hardware interface is a problem. It also includes how to work with the a basic set of tools.
core hardware: Target 3.1 identify different types of preventive maintenance measures, product and procedures, as well as when and how to use them.
this goal involves tools, procedures and consumables participation keep the system clean and performing preventive maintenance. previous wording : the purpose of identification of different types of preventive maintenance and product procedures, as well as use them at any time.
most notable added that here is clean and removable media verify the ups and downs suppressor. other topics considered is not listed earlier including cleaning monitor, control dust and moisture on the internal PC, and performance and disk defragmenting check.
core hardware: Target 3.2 determine the safety measures and procedures, and when / how to use them .
this goal, and in the next one (3.3) was originally a single goal have been split for the revision. goal of 3.2 procedures, in order to prevent suffer harm to the user or computer technicians, as well as The original wording is: identify the problems, procedures and equipment for the protection of computer environmental impacts, including people, hardware, and the surrounding room to work.
have nothing new here these topics are simply a subset of Before topics as the goal. only change is that the ESD prevention measures are spelling a more detailed description.
core hardware: Target 3.3 determine environmental protection measures and procedures, and when / how to use them .
As mentioned above, this goal in the last (3.2) was originally a single objective. this new goal, deals specifically with the environmental impacts of handle all kinds of spare parts and consumables, all that part of the original goal of 3.2. are nothing new.
core hardware: Target 4.1 distinction between popular CPU chip, their basic characteristics wording of this goal remains unchanged. only new issue here is L3 cache memory.
core hardware: Target 4.2 identify the types of RAM, form factors, and operational characteristics.
and the speed of a banks request, in view of scenarios.
this goal is not much change, the latest addition to the more RAM technology topic. original wording is: identify types of RAM (random access memory) terminology, location and physical characteristics.
this goal is now to a special appeal to the sodimms, microdimms, demobilization, as well as Rambus, it did not have before, but in addition it more simple clear specific repeat the theme of the previous list. It also specifically mentioned ECC with non-ECC, and now single and dual distinction Surface memory.
core hardware: Target 4.3 to identify the most common types of motherboards, their parts and components, and its structure (Bus Architecture).
main difference is that the topic of power supply has been removed.
past the wording of the objective results as follows: to identify the most common types of motherboards, their parts and components, and its structure (bus structure and power supply).
this goal seems to be a very big topic had not previously included, but many of them simply enumerations of the topic was implicitly included in the ago, for example, according to communications ports, memory and processor sockets, this goal is now list all types, you need to know specific. also brought 32 and 64 of the speed of PCI and AGP. new mentioned include AMR (audio modem Riser) slot, the Community Rehabilitation Network (Communication Network Riser) slot and chipset.
core hardware: Objective 4.4 determine the purpose of CMOS memory, its contents, as well as how and when change its parameters. CMOS involved in the situation, choose appropriate course of action.
essentially the same wording, and here the earlier version, as follows: identification of the purpose of CMOS (complementary metal oxide semiconductor) It includes how to change its basic parameters.
the same basic topic is covered in the meantime, a couple of small additions such as disable onboard devices, disable anti-virus protection, and work and power management settings, as well as infrared.
core hardware: Target 5.1 determine printer technology, interface and options / upgrade new version launched Options / upgrade, but in other respects the same. that previous version is: the basic concept, printers and printer business group Some 10%.
several new printer technology, has been added here, such as the solid ink thermal dye sublimation. several new interface also added , including the SCSI, IEEE 1394 and wireless.
core hardware: Target 5.2 common understanding of the issues and the printers use technology to solve these problems.
objective even if the wording did not mention the preventive maintenance (the "care") As the previous wording (see below) , and the topics covered include those project. new projects, including the printer firmware and color correction. former wording : determined by the care and service skills and common problems and primary schools printer type.
some of the many new issues, including here on the printer driver, firmware updated calibration, printing a test page, memory, configuration, network and local connections, consumables and the environment.
core hardware: Target 6.1 identify the various types of common network cable, and its characteristics and connector.
This is a new target, although some people, and it is the predecessor of covering other areas.
many new cable and connector types here that were not on the previous version of the test, but realistically speaking Many of them are fuzzy not enough, and they are not likely to appear in the examination. some of the many types The emergence of cable TV in here, including all types of coaxial cable, UTP cable, Sewage treatment plant and fiber, and their joint , including a high current RJ - 45, aui, St. / SC, and IDC / Luen Fat.
core hardware : Target 6.2 establish basic network concepts, including how to network engineering.
this goal, and in the next one (6.3) before a single target have been split up, and is continually expanding. original objectives are: identify basic network concepts, including how the network works, and consequences maintenance services network.
notice pointed out that the current version 6.2, does not include any troubleshooting or repair. most of the issues in this goal are new to the list, including bandwidth, protocols, cabling, network model, infrared and wireless technologies.
core hardware: 6.3 identify common objectives of the existing technology and establish Internet connections and characteristics of This is a the goal of the new struggle, after separating from the objective 6.2. almost presents a whole new issue, which includes a comprehensive list of Internet technology and its features, such as LAN, DSL, cable, ISDN, dial-up, satellite and wireless technologies.
next week: what faithe bad new for 2003 in the operating system + technical examination.
