Computer Networks

To solve this question, the user needs to know the characteristics of a peer-to-peer network.

The statement "Peer-to-Peer network are not flexible" is not entirely true. Peer-to-peer networks are actually flexible in nature since they are decentralized and do not rely on a central server. Each node in a peer-to-peer network can act as both a client and a server, allowing for greater flexibility in terms of sharing resources and data. Moreover, peer-to-peer networks can also be easily expanded or reduced in size, making them more adaptable to changes in network traffic.

Therefore, the correct answer is:

The Answer is: B. False

A remote computer is the system you control or work with over a network connection from another location. This could be through Remote Desktop Protocol (RDP), SSH, VNC, or similar remote access technologies. The computer you're physically using is the local computer.

Flow control manages the rate of data transmission to prevent overwhelming the receiver. This is a transport layer responsibility, implemented by protocols like TCP through windowing mechanisms. The data link layer can also provide flow control (like in HDLC), but the primary OSI flow control is at Layer 4.

Repeaters and hubs operate at the physical layer (Layer 1) of the OSI model. They regenerate and amplify electrical signals to extend network transmission distance but have no intelligence to read or process data. The physical layer deals with raw bit transmission.

To answer this question, the user needs to have a basic understanding of the OSI (Open Systems Interconnection) model and its different layers.

Bit synchronization refers to the process of coordinating the start and end points of a data transmission between two devices. This ensures that the receiving device can properly interpret the transmitted data.

Now, let's consider each option and see which layer is responsible for bit synchronization:

A. Physical: This layer is responsible for the transmission and reception of raw bit streams over a physical medium. It deals with physical connections and electrical signals. Bit synchronization is indeed handled at this layer, so option A is a correct answer.

B. Network: This layer is responsible for the routing and forwarding of data packets between different networks. It does not deal with the physical transmission of data, so option B is incorrect.

C. Physical: This is just a repeat of option A, so it is also correct.

D. Data Link: This layer is responsible for the establishment and maintenance of reliable data links between adjacent nodes. While it does handle some aspects of bit-level synchronization, such as framing, it is not responsible for the overall synchronization of data transmission. Therefore, option D is incorrect.

E. Presentation: This layer is responsible for the translation, compression, and encryption of data. It has no role in the synchronization of data transmission, so option E is incorrect.

Therefore, the correct answer is:

The Answer is: A. physical

To answer this question, the user needs to have a basic understanding of the layers of the OSI model and the functions of each layer.

Bridges operate at the Data Link layer of the OSI model. This layer provides node-to-node data transfer, and it oversees data link protocols such as Ethernet. Bridges are used to connect network segments at the data link layer and are responsible for forwarding frames between these segments.

Therefore, the correct answer is:

The Answer is: B. data link

When installing Windows 2000 Server from a network share on an unpartitioned disk, booting with a Windows 98 network boot disk allows you to create and format a FAT32 partition (which Windows 98 supports and Winnt.exe can install to), connect to the network share, and run the Winnt.exe setup program. This is the standard network-based installation method. Creating a boot floppy with NTLDR (Option B) is for systems that already have Windows installed. Dsclient.exe (Option C) is for Directory Service client tools, not setup. Option D is incomplete. Makebt32.exe (Option E) creates startup disks for local CD-ROM installations, not network installs.

The star-bus (or tree) topology is the most common in modern corporate networks, combining the centralized management of a star topology with the scalability of a bus backbone.

Token Ring architecture is recommended under high network utilization (70-80%) because of its deterministic token-passing access method, which eliminates collisions and provides predictable performance. Ethernet bus (CSMA/CD) performance degrades significantly under load due to collision handling and exponential backoff. FDDI and DLC are not suitable answers - FDDI uses token passing but wasn't listed as the recommended architecture in this context.

DSLAM stands for Digital Subscriber Line Access Multiplexer. It's a network device used by ISPs to connect multiple DSL subscribers to the internet. A multiplexer combines multiple signals into one, which is exactly what a DSLAM does - it aggregates multiple DSL connections for transmission to the internet. 'Multiplier' is incorrect in this context.

Universal Network Objects (UNO) is the component model for OpenOffice.org and LibreOffice, allowing for interoperability between different programming languages and objects across a network. The other options are plausible-sounding but incorrect fabrications.

Bluetooth, GSM, and IEEE 802.11 (WiFi) are all wireless communication standards. TokenRing is wired networking, ATM is a cell-switching protocol, and WAP is a protocol for mobile web access (not a wireless tech itself).

ATM indeed stands for Asynchronous Transfer Mode, which is a telecommunications technology used for transferring digital information. It uses asynchronous time-division multiplexing and was commonly used in telecommunications networks and computer networks. The statement is correct.

Internet2 is a not-for-profit consortium (founded in 1996) that develops and deploys advanced network technologies for education and research. It's not a new cabling system, browser standard, or local area network - it's an association of universities, government, and industry working together on advanced Internet applications and infrastructure.
