IBPS Exam : Computer Awareness Questions Bank -1

Here is the important expected Computer Awareness Questions Bank -1 for IBPS Bank PO/SO/Clerk, RRB, RBI Officer and Assistant Exam. These Computer Network Questions and Answers are must for every aspirants.

Q.1. The connection points between the Network Layer and the Transport Layer is the IP number(s) whereas the connection points between the Transport Layer and the upper layers are called Ports which are represented by 16 bits in the TCP segment header. 

Q.2. Unlike TCP the Transport Layer Protocol UDP is a connectionless protocol. 

Q.3. The programmatic connection between the Network Layer and the upper (application) layers is usually established by small software running in Transport Layer. These are usually called Sockets. 

Q.4. In a 802.3 LAN, IP to ethernet address translation is performed by/with ARP which stands for Address Resolution Protocol. 

Q.5. In an IP address with CIDR standard a quad can range from 0 to 255. 

Q.6. Bluetooth uses Time Division Multiplexing. 

Q.7. A Bluetooth network with 7 active slaves is called a Piconet. 

Q.8. Bluetooth standard specifies 13 applications which are called profiles. 

Q.9. As modulation technology, Bluetooth employs FSK with 1M bps. 

Q.10. The number of necessary OSI layers in a bridge is two 

Q.11. Routers and Gateways are internetworking-connecting devices 

Q.12. A networked computer must minimally have a host-IP, a netmask and default gateway-IP numbers set up in order to do IP-networking properly. 

Q.13. An IP-address with all host bits set to 1 is called Broadcast address. 

Q.14. A Class-B IP-range may have about 65000 hosts in it. 

Q.15. IEEE-802.3 defines broadcast networks standards. 

Q.16. The word ‗Base‘ in 10BaseT identifies the media as baseband. 

Q.17. The letter ‗T‘ in 10BaseT indicates that it is a twisted-pair cable. 

Q.18. An ethernet address with all bits set to 1 is called ethernet broadcast address. 

Q.19. CIDR addressing scheme allows us to create subnets for efficient IP use. 

Q.20. ARP is a process of obtaining ethernet addresses from IP-addresses. 

Q.21. Performance of a network is usually measured by the amount of data transferred per unit time. 

Q.22. Reliability of a network is usually measured by the frequency of failure (inverse of it). 

Q.23. Logical to physical addressing conversion is done in the Network Layer. 

Q.24. In stop and wait flow control method receiver ACKs each data frame received. The alternative to this is called sliding window. 

Q.25. CSMA stands for "Carrier Sense Multiple Access" which is standardized in IEEE 802.3. 

Q.26. The 10 Mbps twisted pair ethernet is usually designated by 10BaseT. 

Q.27. Ethernet or NIC addresses are 48 bit unique numbers used to identify physical devices in CSMA/CD networks. 

Q.28. Bridges divide the networks into smaller segments in order to reduce traffic. 

Q.29. Repeaters and Bridges are networking connecting devices. 

Q.30. In class-B IP-addresses 16 and 16 bits are reserved for host and network identification respectively.
