Computer Networks Questions
-
PING
-
PULSE
-
SONAR BEACON
-
None of these
A
Correct answer
Explanation
PING is a network utility named after the sonar term for a pulse that helps find objects. In networking, it performs a similar function by sending packets to check if a host is reachable and measuring response time.
-
Sun Microsystems
-
IBM
-
Intel
-
Cisco
A
Correct answer
Explanation
Sun Microsystems' 'The network is the computer' was a visionary slogan that anticipated cloud computing and network-centric computing. It reflected their Java and enterprise systems philosophy. This tests tech history and brand positioning.
-
CICSO
-
SUN MICROSYSTEMS
-
EBAY
-
DLINK
B
Correct answer
Explanation
Sun Microsystems coined 'The Network is the Computer' in the 1990s to emphasize their distributed computing vision. This slogan captured the shift from standalone desktops to interconnected systems, central to Sun's business model. Cisco (CICSO in options, note typo) focuses on networking hardware, while eBay and D-Link operate in different market segments.
-
WebSphere
-
Apache
-
IIS
-
Sun Java System Web Server
-
Both A & D
B
Correct answer
Explanation
Apache HTTP Server is the most widely used open-source web server software, freely available for anyone to use and modify. WebSphere is IBM's proprietary commercial web server, IIS is Microsoft's proprietary server, and Sun Java System Web Server (now Oracle) is also closed-source.
-
IBM
-
Sun Microsystem
-
CISCO
-
Cognizant Technologies
B
Correct answer
Explanation
Sun Microsystems coined the famous tagline 'The Network is the Computer', reflecting their vision of network-centric computing and distributed systems. IBM, CISCO, and Cognizant are technology companies but use different taglines. This question tests knowledge of tech industry slogans.
-
A client
-
A host
-
A web server
-
A router
A
Correct answer
Explanation
A client is a computer or program that requests data or services from a server, which is the computer providing the resources. A web server responds to requests, a host is any device on a network, and a router directs traffic between networks.
-
Laptop
-
Office
-
Network
-
I-Security
C
Correct answer
Explanation
Réseau is the French word for network, referring to interconnected systems or social connections. Network is the correct English translation. Laptop and Office are unrelated French technology terms.
B
Correct answer
Explanation
Ascenseur is the French word for lift or elevator, used to transport people vertically between floors. Lift is the correct English equivalent, commonly used in British English. Network and Door are unrelated French vocabulary terms.
-
Computer
-
Laptop
-
Network
-
Elevator
B
Correct answer
Explanation
Portatif in French means portable or mobile, commonly referring to a laptop computer (ordinateur portatif). Laptop is the best answer as it represents a portable computing device. Computer is too general, and Network is unrelated.
-
Serves as an interface between a computer and another computer or devices.
-
Serves as an interface between two software.
-
Serves as an interface between hardware and software.
-
Serves as an interface between CPU and RAM.
A
Correct answer
Explanation
In computing, a port is a physical or virtual connection point that serves as an interface between a computer and external devices or other computers. Ports allow data transfer between systems - examples include USB ports for connecting peripherals, network ports for internet connectivity, and serial/parallel ports for various devices.
-
Communication server
-
Print server
-
File server
-
None of the Above
C
Correct answer
Explanation
A file server is a network server dedicated to storing and managing files so that multiple users on a LAN can access shared programs and data. Communication servers handle network connections, print servers manage printers, and file servers specifically handle file sharing - which is exactly what the question describes.
-
Bus
-
Star
-
Ring
-
Double ring
A
Correct answer
Explanation
In bus topology, all devices share a single backbone cable. If that main cable breaks anywhere, the entire network fails because the backbone is the communication path for all nodes. In star topology, only the disconnected node fails. Ring and double ring can often recover from breaks using dual rings or token reconfiguration.
-
Bus
-
Star
-
Ring
-
None of the Above
B
Correct answer
Explanation
Star topology is preferred for large networks because it offers better scalability and easier troubleshooting. All devices connect to a central hub or switch, making it simple to add or remove nodes without disrupting the entire network. Bus and ring topologies become impractical at scale due to single points of failure and collision management issues.
-
STP server
-
Hub/switch
-
PDC
-
Router
B
Correct answer
Explanation
In a star topology, all devices connect to a central hub or switch that acts as the central connection point. This central device manages communication between all connected nodes. STP servers and routers serve different purposes in networking, while PDC relates to domain controllers.
-
ARCnet
-
Ethernet
-
ARPAnet
-
Sancharnet
B
Correct answer
Explanation
Ethernet uses CSMA/CD (Carrier Sense Multiple Access with Collision Detection) as its media access control method. This protocol helps manage how devices share the communication medium and handle collisions when multiple devices transmit simultaneously. ARCnet uses token passing, while ARPAnet and Sancharnet use different access methods.
