Understanding Computer Specs and Networks

What metric is commonly used to measure CPU performance?

• Memory Size (GB)

• Cache Latency (ns)

• Clock Speed (GHz) and Instructions Per Cycle (IPC)

• Thermal Design Power (W)

Which type of storage device uses flash memory?

• Magnetic tape drives

• USB flash drives, solid-state drives (SSDs), and memory cards

• Hard disk drives (HDDs)

• Optical discs (CDs/DVDs)

What is a star topology in networking?

• A star topology connects nodes in a linear fashion.

• A star topology has no central device and connects nodes directly to each other.

• A star topology is a wireless network configuration without any physical connections.

• A star topology is a network layout where all nodes are connected to a central hub or switch.

What does an IP address identify in a network?

• A method for encrypting data in transit.

• A specific device or interface on a network.

• A type of network cable used for connections.

• A network protocol for data transmission.

Which wireless standard operates at 2.4 GHz and 5 GHz?

• Wi-Fi (IEEE 802.11 standards)

• NFC (Near Field Communication)

• Zigbee (IEEE 802.15.4)

• Bluetooth (IEEE 802.15 standards)

What is the purpose of a CPU cache?

• To replace the main memory entirely.

• The purpose of a CPU cache is to speed up data access for the CPU by storing frequently used data and instructions.

• To increase the CPU's power consumption.

• To store all data permanently for the CPU.

What is the difference between SSD and HDD?

• SSDs use mechanical parts while HDDs are solid-state drives.

• SSDs are cheaper and have larger storage capacities than HDDs.

• SSDs are faster and more durable than HDDs, which are slower and use mechanical parts.

• HDDs are faster and more reliable than SSDs.

What is a mesh network topology?

• A mesh network topology connects devices in a star formation.

• A mesh network topology is a network where each device is interconnected, providing multiple pathways for data.

• A mesh network topology is a linear arrangement of devices.

• A mesh network topology requires a central hub for communication.

What is the function of a subnet mask?

• To define the network and host portions of an IP address.

• To assign IP addresses to devices automatically.

• To encrypt data transmitted over the network.

• To determine the speed of the network connection.

Which wireless communication standard is known for high speed?

• NFC

• Wi-Fi 6 (802.11ax)

• Zigbee

• Bluetooth 5.0
