Q

What network topology uses a token to communicate with?

A. Bus Topology

B. Ring Topology

C. Star Topology

D. Mesh Topology

A

B. Ring Topology

A token ring is a data link for a local area network (LAN) in which all devices are connected in a ring or star topology and pass one or more tokens from host to host. A token is a frame of data transmitted between network points. Only a host that holds a token can send data, and tokens are released when receipt of the data is confirmed. IBM developed token ring technology in the 1980s as an alternative to Ethernet.

Q

Convert binary 1001100 to a decimal number.

A. 75

B. 76

C. 101

D. 52

A

B. 76

Divide by 2 until you get 1. (ignore remainder)

0 = even, 1 = odd

1 = 2/2 = 4/2 = 9/2 = 19/2 = 38/2 = 76/2

1 0 0 1 1 0 0

Q

In a “Star” topology network, what device provides the central connection point?

A. Network switch or hub

B. Network Interfacing Computer

C. Router

D. The bus or “daisy chain”

A

A. Network switch or hub

In the Star Topology there is a central connection point called the hub which is a computer hub or sometimes just a switch. In a Star Network the best advantage is when there is a failure in cable then only one computer might get affected and not the entire network.

Q

Name two styles of connectors that are used on fiber-optic cables.

A. Straight Tip and Subscriber Connector

B. RJ45 and Coaxial

C. Straight Tip and Coupling

D. Optic Coupling and Fiber Subscriber

A

A. Straight Tip and Subscriber Connector

SC stands for subscriber connector and is a standard-duplex fiber-optic connector with a square molded plastic body and push-pull locking features. SC connectors are typically used in data communication, CATV, and telephony environments.

ST stands for straight tip, a high-performance fiber-optic connector with round ceramic ferrules and bayonet locking features. ST connectors are more common than SC connectors.

A.Middle Ware

B.CSMA/CD

C.Firewall Software

D.MAU Ware

A

B. CSMA/CD

Carrier Sense Multiple Access with Collision Detection (CSMA/CD) is a network protocol for carrier transmission that operates in the Medium Access Control (MAC) layer. … On detection of a collision, the station stops transmitting, sends a jam signal, and then waits for a random time interval before retransmission.

In computing, input/output (I/O, or informally io or IO) is the communication between an information processing system, such as a computer, and the outside world, possibly a human or another information processing system. Inputs are the signals or data received by the system and outputs are the signals or data sent from it. The term can also be used as part of an action; to “perform I/O” is to perform an input or output operation.
