Distributed Technologies Quiz

What is a computer network?

• A collection of autonomous computers

• A single computer system

• A hardware device

• A type of software

Answer explanation

A computer network is defined as a collection of autonomous computers that communicate and share resources. This distinguishes it from a single computer system, hardware devices, or software, which do not encompass multiple independent computers.

What does LAN stand for?

• Limited Area Network

• Local Area Network

• Large Area Network

• Long Area Network

Answer explanation

LAN stands for Local Area Network, which refers to a network that connects computers within a limited area, such as a home, school, or office. The other options do not accurately describe this type of network.

Which of the following is a type of network that covers city areas?

• MAN

• PAN

• LAN

• WAN

Answer explanation

A MAN (Metropolitan Area Network) is designed to cover city areas, connecting multiple LANs within a specific geographic region. In contrast, PAN, LAN, and WAN serve different scopes, making MAN the correct choice.

What is the primary purpose of a computer network?

• Data storage

• Data exchange

• Data processing

• Data encryption

Answer explanation

The primary purpose of a computer network is data exchange, allowing devices to communicate and share information efficiently. While data storage, processing, and encryption are important, they are secondary to the core function of exchanging data.

Which device is used to connect different networks?

• Hub

• Switch

• Router

• Modem

Answer explanation

A router is used to connect different networks, directing data between them. Unlike hubs and switches, which operate within a single network, routers manage traffic between multiple networks, making them essential for internet connectivity.

What is middleware in distributed systems?

• Software that connects different applications

• A type of hardware

• A network protocol

• A programming language

Answer explanation

Middleware is software that facilitates communication and data management between different applications in a distributed system, making it the correct choice. It is not hardware, a network protocol, or a programming language.

What is a characteristic of distributed applications?

• They run on a single computer

• They require no network

• They appear as one system

• They are only for local use

Answer explanation

Distributed applications often consist of multiple components that work together over a network, making them appear as a single system to users. This characteristic distinguishes them from applications that run locally on a single computer.

Which of the following is an example of a distributed application?

• Spreadsheet software

• Word processor

• Text editor

• Online banking

Answer explanation

Online banking is a distributed application as it operates over a network, allowing users to access their bank accounts remotely. In contrast, spreadsheet software, word processors, and text editors are typically local applications.

What is the client-server model?

• A type of network architecture

• A programming language

• A hardware specification

• A database model

Answer explanation

The client-server model is a type of network architecture where clients request services and servers provide them. This structure enables efficient resource sharing and communication between devices.

What is task partitioning in distributed processing?

• Dividing a process into smaller tasks

• Combining tasks into one

• Running tasks sequentially

• Eliminating tasks

Answer explanation

Task partitioning involves dividing a process into smaller tasks, allowing for parallel execution in distributed processing. This enhances efficiency and resource utilization, making the correct choice 'Dividing a process into smaller tasks'.
