Computer networks involve the architecture, protocols, and security measures used for digital communication. This collection covers OSI model layers, IP addressing, data transmission, and cryptographic standards. These concepts are vital for the computer knowledge sections of banking and government exams.

Computer Networks Questions
-
still ip is not secure
-
long host address
-
inclusion of ipsec
-
strong access list features
C
Correct answer
Explanation
IPv6 was designed with IPsec as an integral, mandatory part of the protocol suite, whereas IPv4 treats IPsec as an optional add-on. This native integration in IPv6 makes security implementation more standardized and ubiquitous.
-
unicast
-
anycast
-
broadcast
-
multicast
C
Correct answer
Explanation
IPv6 removed the broadcast addressing mode that existed in IPv4. Instead, IPv6 uses multicast for one-to-many communication. Unicast, anycast, and multicast all exist in IPv6, but broadcast was eliminated to improve efficiency.

dhcpv6
-
arp6
-
icmpv6
D
Correct answer
Explanation
In IPv6, ARP (Address Resolution Protocol) is replaced by ICMPv6 through the Neighbor Discovery Protocol (NDP). ARPv6 doesn't exist, and DHCPv6 is for address configuration not address resolution. ICMPv6 handles neighbor solicitation and advertisement.

just fact
-
freebie (this is right answer)
-
no no no
C
Correct answer
Explanation
This is a freebie question testing attention rather than technical knowledge. The content itself explicitly states 'this is right answer' for option C. The other options are intentionally dismissive ('no no no', 'just fact').

Digital Transmission Protocol
-
DeskTop Publishing
-
Data Type Programming
-
Document Type Processing
B
Correct answer
Explanation
DTP stands for DeskTop Publishing, which refers to the creation of documents using page layout software on a personal computer. It combines text and graphics to produce professional-quality printed materials like brochures, newsletters, and books.
-
Network Address Translation
-
Network Administration Tool
-
Novell Address Transfer
-
Newly Added Technology
A
Correct answer
Explanation
NAT (Network Address Translation) is a method used in networking to remap IP addresses by modifying network address information in packet headers. It allows multiple devices to share a single public IP address, conserving address space.

B
Correct answer
Explanation
In computer terminology and publishing software, 'DTP' stands for Desktop Publishing. This refers to the creation of documents using page layout software on a personal computer, combining text and graphics to produce professional-quality printed materials such as brochures, newsletters, and books.

Newly Added Technology
A
Correct answer
Explanation
NAT (Network Address Translation) is a router function that allows multiple devices on a local network to share a single public IP address when accessing the internet. It translates private IP addresses to a public one and vice versa. This conserves IP addresses and adds a layer of security by hiding internal network addresses.
C
Correct answer
Explanation
Option C is correct: The analytics plugin uses SAWTCP protocol to communicate with BI Presentation Services. Options A (TCP) and B (UDP) are incorrect protocols. Option D (HTTP) is used for web browser communication, not plugin communication.
A
Correct answer
Explanation
Microsoft Remote Desktop Protocol (RDP) uses port 3389 as the default port for Terminal Server connections.
A
Correct answer
Explanation
Telnet protocol uses port 23 by default for unencrypted text-based remote terminal connections and command-line access.
A
Correct answer
Explanation
LDAP uses port 389 as the default port for directory service operations. Port 636 is used for LDAPS (LDAP over SSL/TLS).
C
Correct answer
Explanation
SMTP uses port 25 as the default port for email transmission between mail servers. This is the standard for mail routing.
C
Correct answer
Explanation
HTTP uses port 80 as the default port for unencrypted web traffic. HTTPS (encrypted) uses port 443.
A
Correct answer
Explanation
HTTPS (HTTP over SSL/TLS) uses port 443 as its well-known port. This is the standardized port for secure HTTP traffic. Port 444, 445, and 441 are used for other services (444 for SNPP, 445 for SMB over TCP).
