COMPUTER NETWORK IS A NETWORK OF INTERCONNECTED COMPUTERS OR SERVER
Correct Answer
A. TRUE
Explanation
A computer network is indeed a network of interconnected computers or servers. This means that multiple computers or servers are connected together, allowing them to share resources, such as files, printers, and internet connections. These interconnected computers can communicate with each other, enabling the sharing of data and information. Therefore, the statement "Computer network is a network of interconnected computers or servers" is true.
4.
Which one has the widest coverage?
Correct Answer
B. WAN
Explanation
WAN stands for Wide Area Network, which is a network that covers a large geographical area, such as multiple cities or even countries. LAN stands for Local Area Network, which covers a smaller area, typically within a building or campus. MAN stands for Metropolitan Area Network, which covers a larger area than a LAN but smaller than a WAN, usually within a city or town. Therefore, WAN has the widest coverage among the three options.
5.
Which one is a type of network that can only communicate less than 30 miles in size but can connect to a 2 - 3 buildings.
Correct Answer
B. MAN
Explanation
A Metropolitan Area Network (MAN) is a type of network that can connect multiple buildings within a range of less than 30 miles. It is designed to serve a larger geographical area than a Local Area Network (LAN) but smaller than a Wide Area Network (WAN). MANs are commonly used by organizations or institutions that have multiple buildings in close proximity, such as universities or corporate campuses. MANs provide high-speed connectivity and allow for efficient communication and data sharing between the connected buildings.
6.
ANYTHING PHYSICALLY CONNECTED TO NETWORK is called _____.
Correct Answer
C. Node
Explanation
A node refers to anything physically connected to a network. This can include devices such as computers, servers, routers, switches, or any other network-enabled device. Nodes are essential components of a network as they allow for the transmission and reception of data within the network infrastructure.
7.
Which one is not an examples of Communications Media
Correct Answer
E. None of the Above
Explanation
The correct answer is "None of the Above" because all the options listed (Cables, Fiber Optics, and Radio Waves) are examples of communication media. Communication media refers to the various channels or means through which information is transmitted, and all three options mentioned are commonly used for communication purposes.
8.
What is a server?
Correct Answer
A. Any combination of hardware or software designed to provide services to clients.
Explanation
A server refers to any combination of hardware or software that is specifically designed to provide services to clients. This can include a physical server machine or a virtual server, as well as the necessary software and configurations to enable the provision of services. The server acts as a central hub within a network, allowing clients to access and utilize various resources or services. It can handle tasks such as storing and serving files, hosting websites, managing databases, or providing network services like email or DNS.
9.
A Client is ____?
Correct Answer
B. ANY PART OF THE NETWORK THAT RECEIVES DATA
Explanation
The term "client" refers to any part of the network that receives data. In a network, there are typically two main components: clients and servers. Clients are the devices or applications that request and receive data from servers. They can be computers, smartphones, or any other device connected to the network. The client's role is to initiate communication with the server and receive the requested data. Therefore, the correct answer is "ANY PART OF THE NETWORK THAT RECEIVES DATA."
10.
NIC IS A A SPECIAL CARD THAT U INSTALL IN THE PC THAT ALLOWS TO PLUG ETHERNET OR WIRLESS CONNECTION IT ALLOWS TO CONNECT TO THE NETWORK. NIC STANDS FOR WHAT?
Correct Answer
Network Interface Card
Explanation
A Network Interface Card (NIC) is a special card that is installed in a PC to enable the connection of Ethernet or wireless connections. It allows the PC to connect to a network, facilitating communication between the computer and other devices on the network.
11.
WHICH ONE IS NOT A TYPE OF TOPOLOGY
Correct Answer
A. TREE
Explanation
The correct answer is TREE because tree is a type of hierarchical network topology where nodes are connected in a parent-child relationship. This type of topology is commonly used in computer networks, but it is not one of the main types of network topologies. The main types of network topologies are star, ring, bus, and mesh.
12.
WHICH ONE IS A COMMON EXAMPLE OF A NIC CARD
Correct Answer(s)
A. WIRELESS CARD
B. ETHERNET CARD
Explanation
The correct answer is wireless card and Ethernet card because both are common examples of NIC (Network Interface Card). A wireless card allows devices to connect to a network wirelessly, while an Ethernet card enables devices to connect to a network using an Ethernet cable. Both cards serve the same purpose of facilitating network connectivity, but through different means.
13.
_______ is a set of rules which is used by computers to communicate with each other across a network.
Correct Answer(s)
Protocol
Explanation
A protocol is a set of rules that governs how computers communicate with each other over a network. It defines the format and order of messages exchanged between devices, as well as the actions to be taken in response to different situations. Without protocols, computers would not be able to understand each other and establish successful communication. Protocols ensure that data is transmitted accurately and efficiently, allowing for seamless network communication.
