Computer Networks Questions
-
Internet Group Management Protocol
-
Internet Gateway Management Protocol
-
Intranet Gateway Management Protocol
-
Internal Group Management Protocol
A
Correct answer
Explanation
IGMP stands for Internet Group Management Protocol, used by IPv4 hosts and routers to manage multicast group memberships. It's not for gateway or intranet management - it specifically handles which hosts belong to which multicast groups.
B
Correct answer
Explanation
TELNET provides bidirectional interactive text-oriented communication through a virtual terminal connection, allowing users to log into remote systems. SNMP is for network device management, POP3 is for retrieving email, and TELNET is the correct answer for terminal emulation.
B
Correct answer
Explanation
DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses and network configuration to clients. FTP is for file transfers, RPC enables remote procedure calls, and DNS resolves domain names to IP addresses.
D
Correct answer
Explanation
ICMP is not a routing protocol - it's used for error reporting and network diagnostics (like ping). OSPF, RIP, and EIGRP are all routing protocols that determine optimal paths for data packets through networks.
-
Enhanced Interior Gateway Routing Protocol
-
Extended Internal Group Routing Protocol
-
Emerging Internal Gateway Routing Protocol
-
Emergent Interior Gateway Routing Protocol
A
Correct answer
Explanation
EIGRP stands for Enhanced Interior Gateway Routing Protocol, a Cisco-proprietary advanced distance-vector routing protocol. It's an enhancement of IGRP (Interior Gateway Routing Protocol), not "Emerging" or "Emergent".
-
Secure Sockets Layer
-
Secret Service Logarithm
-
Systematic Security Level
-
Secured Service Level
A
Correct answer
Explanation
SSL (Secure Sockets Layer) is a standard security technology for establishing an encrypted link between a server and a client. The link ensures that all data passed between the web server and browser remains private and integral.
-
File Transfer Protocol
-
Fake Transfer Protocol
-
File Truncate Protocol
-
None of these
A
Correct answer
Explanation
FTP stands for File Transfer Protocol. It is a standard network protocol used for the transfer of computer files between a client and server on a computer network. 'Fake' and 'Truncate' are incorrect terms in this context.
-
The time taken to transfer a web page
-
Standards of communication between two or more computers
-
The size of the e-mail attachment
-
None of these
B
Correct answer
Explanation
A protocol is a standardized set of rules and conventions that govern communication between devices on a network. In the context of the internet, protocols like HTTP, FTP, and TCP/IP define how computers exchange data reliably. Option A refers to transfer time, which is a performance metric, not a communication standard. Option C refers to email attachment size, which is unrelated to protocols.
-
Use the Send To field
-
Use the CC field
-
Use the BCC field
-
None of these
C
Correct answer
Explanation
BCC stands for Blind Carbon Copy. When you put an address in the BCC field, that recipient receives the email, but their address is not visible to the primary recipient (To) or the CC recipients.
-
Zone Alarm Pro
-
Comodo Firewall
-
Hit-Fire
-
Threat fire
B
Correct answer
Explanation
Comodo Firewall is a well-known free firewall software for Windows. Zone Alarm Pro is a paid commercial product (though a free version exists), while Hit-Fire and Threat fire are not recognized firewall products.
-
Simple Mail Transfer Protocol
-
Single Mail Transfer Protocol
-
Simple Message Transfer Protocol
-
Single Message transfer Protocol
A
Correct answer
Explanation
SMTP correctly stands for Simple Mail Transfer Protocol. It is the standard protocol for email transmission across the internet, working on port 25 by default. The protocol handles sending emails from a mail client to a mail server or between mail servers.
-
Stand alone PC
-
Network environment
-
Both
-
None of the Above
B
Correct answer
Explanation
The ISO OSI (Open Systems Interconnection) model is specifically designed for network environments to standardize communication between different systems and protocols. It's not relevant for standalone PCs that don't participate in network communication. The model provides a framework for network protocol development and implementation.
-
File Transport Protocol
-
Form Transfre Protocol
-
File Transfer Protocol
-
File Transfer Program
C
Correct answer
Explanation
FTP stands for File Transfer Protocol, a standard network protocol used for transferring files between a client and server on a network. File Transport Protocol, Form Transfre Protocol, and File Transfer Program are incorrect.
