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 computerâyou 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
΄ou have to sign in to Windowsâdoes it matter if the CAPS LOCK light on the

difficult to know which icon to choose when switching between them. What
alternative method could you suggest?
Press Alt+Tabâthis shows previews of the window. Windows can also
show previews of the window contents when pointing at the taskbar icon.

technique could he use to be more productive?
Use the mouse scroll wheel (or if it doesn't have one drag the scroll

FalseâWindows 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

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.
Falseâordinary 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

approach multiple problems individually. If you are following CompTIA's
troubleshooting model, what other piece of advice should you give?
Determine if anything has changedâthis 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

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
