1. Star and Tree
2. Tree and Ring
3. Star and Ring

1. None of the given

In Point-to-Point topology there are two topologies.

1. STAR topology
2. TREE topology

Q2. ------ Program sends a message to a remote computer and reports whether the computer responds.

Ping

1. Traceroute
2. ICMP
3. Non of the given

Ping program tests reach ability. It sends datagram from B to A, that echoes back to B. it uses ICMP echo request and echo reply messages.

Q3. ------ has no way to determine the cause of the problem.

1. ICMP

Ping

1. Trace route
2. Non of the given

Ping has no way to determine the cause of the problem. Tracing A Route Network administrators use another tool, trace route.

Q4. The term----- ------- refers to the general concept of a small block of data

Packet

1. Frame
2. Data
3. None of the given

Packet is a generic term that refers to small block of data. Packet have different format. Each hardware uses different packet format.

Q5. ---------- scheme, which is designed to help detect transmissions errors, send one extra bit of information with each character

1. Parity
2. Checksums
3. CRC
4. None of given

Correct answer: Parity

A parity scheme, which is designed to help detect transmission errors, sends one extra hit of information with each character. Although it allows receiver to determine if a single bit has been changed parity can not detect transmission errors that change an even number of bits.

Q6. Local Talk is a LAN technology that employs -------------

1. Bus topology
2. Ring topology
3. Star topology
4. None of the given

Correct answer: Bus topology

LOCAL TALK: Apple invented the LAN technology that uses bus topology. Its interface is included with all Macintosh computers.

Q7. Most LANs that employ ring topology use an access mechanism known as-------

1. CSMA/CD
2. CSMA/CA
3. TOKEN PASSING
4. None of the given

Correct answer: TOKEN PASSING

Most LANs that employ ring technology use an access mechanism known as . A token ring operates as a single, shared medium. When a computer wants to send data, it must wait until it obtains the token, when it is in control of the ring

Q8. Ethernet uses a ------ bit static addressing scheme in which each device is assigned a unique address by the manufacturer.

1. 64
2. 48
3. 32
4. 8

Correct answer: 48

Ethernet uses a 48-bit static addressing scheme

Q9. Formally named __________ informally known as the thick wire Ethernet or Thick net.

1. 10 Base 2

Q10. Base 5

1. 10 Base T
2. None of the given

Thick Ethernet, officially known as 10 Base 5, is the oldest form of Ethernet. It was originally developed in the late 1970's by Digital Equipment Corporation, IBM, and Xerox, and became an international standard (IEEE 802.3) in 1983.

Q10. Formally named __________ informally known as the twisted pair Ethernet or TP Ethernet.

1. 10 Base 2
2. 10 Base 5
3. 10 Base T
4. None of the given

Correct answer: 10 Base T

twisted pair ethernet Formally called 10 Base –T Also twisted pair Ethernet or simply TP Ethernet

Q11. The maximum size of an Ethernet segment is___________

1. 250 meters

Q500. meters

1. 700 meters
2. None of the given

One Ethernet cable is sometimes called a segment. This segment is limited to 500 meters in length. The minimum separation between connections is 3 meters. (P# 27)
