ITF Module 1 Review Questions, CompTIA ITFundamentals+ Module 1 (copy)

True or false? All types of computers use CPU and system memory

True or false? All types of computers use CPU and system memory

True

What type of computer is most likely to need peripheral devices?

Desktop computer—you could also call this a Personal Computer (PC)

or a workstation. An All-in-one PC also uses peripheral devices, with the

obvious exception of a monitor.

What type of computer is best suited for using in a job where you have to make

notes and be able to move around easily?

A tablet or smartphone or possibly a hybrid laptop/tablet. Notetaking is

supported by a touchscreen-based device.

Why don't laptops make good servers?

There is no room for expansion and you are paying for components and

design (maximum portability) you do not need.

Why isn't a smartphone a good tool for writing a report?

Touchscreen or mini keyboards are not optimized for writing lots of

text, though it is possible to attach them as peripheral devices.

What type(s) of IoT appliance are less likely to be controlled via a home

automation hub?

Modern cars and medical devices are unlikely to interface via a hub.

Home automation hubs link to kitchen and domestic appliances,

streaming media players, and potentially security systems.

What should you do before attempting to set up a new computer system?

Verify that the environment is suitable and that the installation will be

safe.

When setting up a desktop computer, what factor should you consider when

deciding on the location of the system case?

You do not want to leave trailing wires over walkways so you need to

consider the position of power outlet(s) and where peripheral devices will

be placed. You also want to ensure adequate air flow around the system

unit.

What factors should you consider when positioning input and output devices?

Ensure that they can be used without exerting strain, especially on the

arms/wrists and back/neck. Ensure that cabling is not a trip hazard. Avoid

locations that cause excessive screen glare

Υou have to sign in to Windows—does it matter if the CAPS LOCK light on the

keyboard is activated?

Yes—passwords are case-sensitive

You have to open a word processing application but you cannot see an icon on

the desktop. What should you do?

Look for the shortcut in Start Menu or Start Screen—not all programs

add shortcuts on the Desktop.

Your colleague has to run many applications at the same time and finds it

difficult to know which icon to choose when switching between them. What

alternative method could you suggest?

Press Alt+Tab—this shows previews of the window. Windows can also

show previews of the window contents when pointing at the taskbar icon.

Your colleague is using a laptop and you notice that he laboriously clicks the

mouse repeatedly to scroll through the document you are co-editing. What

technique could he use to be more productive?

Use the mouse scroll wheel (or if it doesn't have one drag the scroll

button in the scroll bar).

What function of an operating system is performed by the "shell?"

Interface between the user and the computer.

What type of file in an OS is the main means of providing coordination of

hardware components?

A driver (or device driver)

What is an example of an open source operating system?

Linux, Chromium, or Android.

What type of computing device(s) is macOS designed for installation on?

Desktop computers/workstations and laptops.

True or false? Windows 10 is the first 64-bit edition of Windows.

False—Windows 10 is better described as a version than edition and

there have been 64-bit editions of Windows versions since Windows XP

You have to open a file located on a network server. What should be your first

step?

Open the Network object from Explorer and locate the server

(computer) hosting the file.

What is the technical term for a web address?

Uniform Resource Locator (URL). In fact, Uniform Resource Identifier

(URI) is now preferred in web standards documentation but URL is more

widely known and used.

What key combination can you use to force the browser to ignore any locally

cached files when refreshing a page?

Ctrl+F5.

What is the registry and how does it distinguish Windows and Linux?

The registry is a database of configuration settings supporting the

Windows OS. Linux uses individual text files to store settings.

What term is used to describe terminating a process that is not responding to

user input?

This is often called "killing" the process.

Why might you use the Services snap-in to manage background processes

rather than Task Manager?

Task Manager allows you to start and stop services but the Services

snap-in also allows you to configure service properties.

The Task Scheduler allows you to run a process automatically in Windows.

What is a widely-used Linux equivalent?

cron is widely used to run tasks automatically in Linux.

What part of the system memory setup is most user-configurable?

Use of virtual memory or a pagefile, where disk space is used to

supplement system RAM.

What two things are configured on a disk to make storage space on the disk

available to the Windows OS?

The disk must contain at least one partition, typically allocated a drive

letter, and the partition must be formatted with a suitable file system.

What is a CLI?

A Command Line Interface allows the user to interact with the OS using

typed commands or scripts rather than a GUI.

What protection feature in Windows is designed to prevent a script or software

from making unauthorized changes to the OS configuration?

User Access Control (UAC). UAC means that the user must input their

credentials or click through an authorization prompt before the

configuration change can be made.

True or false? A standard user cannot change their own password.

False—ordinary users can change their own password but cannot

change anyone else's.

You are advising a colleague about best practices when troubleshooting. You

have identified the following techniques to use to identify a problem: gather

information, duplicate the problem, question users, identify symptoms, and

approach multiple problems individually. If you are following CompTIA's

troubleshooting model, what other piece of advice should you give?

Determine if anything has changed—this is one of the most useful

troubleshooting techniques.

You have asked a senior manager to authorize your plan of action for resolving

a fault in a software application. What name is given to the process you are

following?

This is escalating the problem. You might escalate a problem to more

experienced staff or seek help with a solution plan that is beyond your

authority to put into action.

You are setting up a new computer, but it doesn't seem to be working. Should

you check anything or contact the manufacturer?

It would be best to double-check you have connected the cables

correctly (especially power).

Your computer locks up periodically and feels hot to the touch. Could these

things be related?

Yes, many lockup problems are caused by overheating. The first step

would be to clean the fan exhaust vents of dust.

What crucial piece of information would you need when trying to locate

support information about a computer system on the manufacturer's website?

The model number or a service code.

If you do not have a support contract, what is likely to be the best option for obtaining advice about a problem with an application?

A product support or community forum.

You are looking for content on a topic but your search is returning millions of

matches that are not particularly helpful. What two methods could you use to

get better search results?

Use more search keywords (ideally with 'uncommon' words) or search

for an exact phrase by enclosing it in quotes

You want to find something on a particular website, but the site does not have

a search tool. Could you use a general search engine, and if so, how?

Yes—you use an advanced search form or use the site: operator (for

example 'certification site:comptia.org').

OS X
