Flashcards for COMPTIA A+

Flashcards are a great way to study for any vocabulary heavy exam. As such, they are perfect for tests like Network+ and especially both A+ exams.

You'll remember port numbers, motherboard types, and information about peripherals. My flashcards below are broken up into sections to help you segment your studying into small, digestible pieces.

Port Numbers

To get started, simply click the protocol you want to study to reveal its port number along with a helpful tip on how to remember it.

SMTP uses port number 25 and is responsible for sending e-mails. To remember what this protocol is used for, use this version of the acronym: Send Mail To People.
The port number is 145. To remember what this protocol does, recognize that SMTP is for sending and IMAP is for receiving.
POP uses port number 110 and is responsible for receiving mail. Remember, POP and IMAP only take, they do not give. The giver of the bunch is SMTP.
SSH uses port number 22. The protocol is used for secure connections so remember, SSH means "Shhhh!" because it's a secret.
RDP uses port number 3389. It is the protocol that enables the use of remote desktop. 3389 is a number that is far away from the other port numbers on the exam. So remember remote equals far away.
HTTPS uses port number 443. It is responsible for secure communications within browsers and other places.
DNS uses port number 53 and is responsible for giving a name to nameless IP addresses.
HTTP uses port 80. It is the insecure version of HTTPS. To remember this, keep in mind that HTTP is less secure and uses a lower port number.
FTP uses port numbers 20 and 21. Remember when transferring files, you want to go through door number 20, 21.

Cable Types

Tranmits at speeds of 100 Mbps over 100 meters.
Tranmits at speeds of 1 Gbps over 100 meters.
Transmits at speeds up to 10 Gbps over a maximum of 55 meters.
Transmits at speeds up to 10 Gbps over a maximum of 100 meters. Remember 6 and 6a have the same speeds but 6a is a lot longer.

Connection Types

The slower USB connection, it has a max speed of up to 480 Mbps.
The faster of the two USB connections with a max speed of up to 5Gbps.
Thunderbolt has the same oval shape as USB type C and is used primarily for video transmission.
You might hear people call this connector type an "Android" charger but its actually compatible with all sorts of devices, even Apple ones. It has largely replaced micro USB.
This is an older standard that is being replaced by USB type C. You will still see this type of connector for some digital cameras, and computer mice.

Command-Line Tools for Microsoft



ACL stands for access control list and is used to determine what type of traffic to permit through your firewall.
MFA stands for multi-factor authentication and consists of the following: some you have (like an ID badge), something you are (a retina scan), and something you know (like a PIN number or password).
