Aryaka Interview Questions

Q4 What do you mean by Ethernet?

Ethernet is a network technology used in LAN, MAN and WAN that connects devices using cables for the transmission of data. It provides services on the Physical and Data Link layers of the OSI Model.

  • Q3 What is a client/ server network?

    A client/ server network is a network where one computer behaves as a server to the other computers. The server is usually more powerful than the clients and serves the clients.

    Q4 What is an encoder?

    An encoder is a program, circuit or a device that converts data from one format to another. Encoders convert analog signals into digital ones.

    Q2 What is a MAC address and why is it required?

    MAC or Media Access Control address is a computer’s unique number assigned to a Network Interface Controller (NIC). It is a 48-bit number that identifies each device on a network and is also referred to as the physical address. MAC addresses are used as a network address for communications within a network such as an Ethernet, Wi-Fi, etc.

    Q3 What is Round Trip Time?

    Round Trip Time or Round Trip Delay Time refers to the time taken for a signal to be sent and the ACK of that signal to be received.

    Q3 Explain what is DNS?

    DNS or Domain Name System is a naming system for devices connected over the internet. It is a hierarchical and decentralized system that translates domain names to the numerical IP Addresses which is required to identify and locate devices based on the underlying protocols.

    All devices connected to the internet have unique IP addresses which are used to locate them on the network. The process involves conversion on hostnames into IP addresses. For example, in case the user wants to load some web page (, this hostname is converted into an IP address that can be understood by the computer in order to load that web page.

    Q4 What is the difference between CSMA/CD and CSMA/CA?


    The effect is after a collision

    The effect is before a collision

    Minimizes the recovery time

    Reduces the possibility of a collision

    Usually used in wired networks

    Usually used in wireless networks

    Q3 What is OSPF?

    OSPF stands for Open Shortest Path First. It is basically a routing protocol that is used to find the best path for packets that are being transmitted over interconnected networks.

    Q What is TCP?

    TCP or Transmission Control Protocol is a connection-oriented protocol that establishes and maintains a connection between communicating devices until both of them are done exchanging messages. This protocol determines how application data can be broken down into packets that can be delivered over a network. It also sends and receives packets to and from the network layer and is in charge of flow control, etc.

    Q4 Explain the RSA algorithm briefly.

    RSA is a cryptosystem used to secure data transmission named after Ron Rivest, Adi Shamir and Len Adleman. This algorithm has a public key for encryption while the decryption key is kept secure or private. The encryption key is created using two large prime numbers and is published along with an auxiliary value. Anybody can make use of this public key for encryption but only someone with the knowledge of the prime numbers can decrypt it. However, this algorithm is considered to be slow and for the same reason, it is not used very often to encrypt data.
