2.7 Basic Networking Concepts Flashcards
The Post Office Protocol v3 (POP3) protocol is for incoming mail. Which protocol is used for outgoing mail?
SMTP
What device is capable of performing packet switching?
A router.
How is an IP Address structured?
An IP address is used to logically identify each device (host) on a given network. The address is either a 32-bit binary value (IPV4) or a 128-bit binary value (IPV6). In IPV4, the IP address is broken into four 8-character binary values called octets. This results in a decimal value between 0 and 255 within each octet.
What protocol is used to retrieve email from a server and supports multiple clients connecting to the same mailbox simultaneously?
Internet Message Access Protocol (IMAP)
What is the networking term that describes the total time it takes a data packet to travel from one node to another?
Latency
What is the advantage of downloading files from a site that begins with HTTPS as opposed to HTTP?
The HTTPS site uses SSL/TLS to encrypt data and provide a secure connection.
What usually happens to email messages when a client accesses them using the Post Office Protocol v3 (POP3)?
The messages are downloaded to the client and deleted from the server.
How does a Uniform Resource Locater (URL) get translated to an Internet Protocol (IP) address?
Using the Domain Name System (DNS) resolution process.
How many Ethernet LAN ports are typically found on a Small Office Home Office (SOHO) network switch?
Four to eight.
What limitation should you be aware of when applying Media Access Control (MAC) filtering on your network devices?
You will need to modify the safe list for each new authorized client device going forward.
What is the primary difference between a LAN and a WAN?
The geographic distance between the devices that are being networked.
Which feature of a wireless router allows you to specify precisely which wireless clients may join your network?
MAC filtering.
Which is NOT a key function of a Small Office Home Office (SOHO) wireless router?
It provides access to 3G and 4G
What is packet switching?
The ability of one computer to forward information to another using any available pathway.
What does Internet Message Access Protocol 4 (IMAP4) allow a user to do that Post Office Protocol 3 (POP3) does not?
View the same email from many different devices.
