Terms in this set (71)
T or F | Layer 4 The Transport Layer is where ports are Controlled
A computer that has a rate of 7,000,000 bits a second should have what speed network adapter.
7mbps (NOT 7MB/s that is Megabytes, mbps is Megabits, A million bits is 1 megabit)
T or F | In task manager you can access the properties of a network adapter
False (it is Device Manager)
When it comes to just recieving information is Half-Duplex or Full-Duplex Faster?
Full-Duplex (It is faster at everything and it can send both ways at the same time)
T or F | A token ring is physically a Star topology but sends data like a ring
Port Number 110 is used by which Protocol?
T or F | Port number 23 is used by Telnet?
True (Telnet is 23, 25 is SMTP)
SSH stands for ________ _______
If your boss asks you to find the current MAC address of his computer what command would you type in CMD
ipconfig /all (It displays the MAC address while ipconfig doesn't)
When a host is Transmitting data will the process start by using the Application Layer or the Physcial Layer?
Application Layer (If the computer was the Receiving Computer it would start with Physical)
T or F | Using the command ping will only use the first Three Layers of the OSI Model Physical, Data Link and Network
True (Layers 2 and 3 are what do cmd commands)
To see the history of your computers MAC addresses what command should you type in CMD
The most common type of switch used on a LAN is ______________
A Layer 2 Switch
Wireless Access Points, Bridges and Network Adapters reside on which layer?
Data Link (Layer 2)
The Protocols FTP, HTTP, POP3 and SMTP are associated with which layer?
Layer 7, Application
T or F | Data Link Layer handles Frames while Network Layer handles Packets
True (Physical Layer also handles Bits)
What is the difference in Internet and Intranet?
The internet is the public network of computers. Intranet is a private network for certain people.
Name the sizes of networks from least to greatest
Pan (Personal), Lan (Local), Man (Metropolitan) & Wan (Wide)
An Intranet allows only people in the company to access it while Extranet allows ____________ to use it.
Some people out of the company
Peer to Peer is where every computer requests and sends information with no central administration. While Client Server is where ________________
Each computer has a role it full fills assigned by the administrator. (Think Anarchy vs Communism)
Client Servers use which two protocols for Emails?
POP3 and IMAP4
NIC (Network Interface Card) is what?
Expansion card on the motherboard that provides a means for network and Internet connections.
Does Class A Networks or Class B Networks have more Useable Addresses?
Class A (Because the default subnet for A is 255.0.0.0, there are more nodes)
Does Class A Networks or Class B Networks have more total number of networks
Class B (Because the default subnet for B is 255.255.0.0 there are more networks)
The IP range of class A networks is
0-127 (Class B's is 128-191, With each letter it goes up you add half the number of how much it went up each time, So Class C would be 192-223)
Cat 7 Ethernet Cabling uses which Wire?
GG45 (The successor to the RJ45)
The Hexadecimal Value of 1D is what in Decimal?
29 (Because 10 in Hexidecimal is 16 in Decimal you go up by 13, and reach another set of ABCDEF after 19)
The Application, Presentation and Session layers of the OSI Model make up what Layer of the TCP/IP Layer?
T or F | Transport and Network layers of the OSI model have their own layers in the TCP/IP model
The Data Link and Physical Layers of the OSI model make up what TCP/IP Layer
A DNS does what:
Changes domain names into the actual IP address.
What is the difference in WINS and DNS
WINS resolves NetBIOS names to IP addresses. DNS is used to resolve domain names.
To find the hosts per subnet you do what math equation
Using that last question how many hosts per subnet does the IPv4 address 188.8.131.52/21 have?
2,046 (This is really long explanation come ask me IRL how to do it)
To find the number of USABLE subnets you do which math equation
2^subnet bits-2 (If you were looking for unusable ones you would take out the minus 2)
Using that last question how many usable subnets does the IPv4 address 184.108.40.206/21 have?
32 (Because the address starts with 172 we know it is a Class B network, so their are 2 sets of octets, taking the 21 at the end and subtracting by 16 it gives you 5, then you do 2^5 to get 32 then you subtract by 2 to get 30)
T or F | A Break in a Bus Topology will disable only that host from the network
False (It will disable the entire network)
T or F | A WAN is the largest type of network size
The port number 1701 is which protocol
L2TP (Layer 2 Tunneling Protocol which is used to support a VPN)
TELNET (Port 23) does what?
It gives you an Unencrypted remote communication
DHCP (Dynamic Host Configuration Protocol, 67-68) does what?
Automatically Assigns IP Addresses, MAC Addresses,etc
NetBIOS Port Numbers are _____-_____
LDAPS (Lightweight Directory Access Protocol Secure, 636) does what?
Stores and receives network information using SSL/TLS
What is the difference in FTP, SFTP and TFTP
FTP transfers files, SFTP does it with SSH and TFTP uses Encryption
RTP (Real-time Transport Protocol) has what port number
The command-line tool used to list a host's active incoming connections is
A Media Access Control (MAC) address identifies a
Network Interface Card (NIC)
______________ is when you can move seamlessly from one access point to another. If the access points all have the same SSID and same encryption and authentication.
Which technology can you use to extend an internal network across shared or public networks?
10 Gigabit Ethernets Maximum segment Length is is ____km
100BaseTX Bandwidth is
100 Mbps (half duplex)
200 Mbps (full duplex)
1000BaseCX (short copper)
Is used for very short distances with a maximum segment length of 25 meters (It uses a special copper wire, while 1000BaseSX and 1000BaseLX is fiber optic)
You need to divide a network into three subnets. Which device should you use?
To directly connect the Ethernet network interface cards (NICs) of two computers, you should use a what?

The Ping Tool is used to do what
Self-test a host's own network interface & Determine whether a host is reachable
What type of DNS record maps host names to addresses?
Host (A) DNS record
Teredo tunneling is a protocol that

Domain Name System (DNS)
In which OSI layer does routing occur?
Network (Layer 3)
