Which of the following are the capabilities of Function-based Integrated System?1. Intended for the exclusive support of a specific application area.2. Share a common set of database files.3. Only one database file implies 0% redundancy and 100% data integrity.4. Database files easily become different if one is updated and the others are not.
- A.
1 and 2 only
- B.
2 and 4 only
- C.
2 and 3 only
- D.
1 and 4 only
Correct Answer
D. 1 and 4 onlyExplanation
Function-based Integrated Systems are designed to support a specific application area exclusively, which is stated in option 1. This means that the system is tailored to meet the specific needs and requirements of that particular application area. Additionally, option 4 states that if one database file is updated, the others easily become different. This implies that there is a lack of synchronization or consistency among the database files, which can lead to data inconsistencies and potential issues with data integrity. Therefore, the correct answer is 1 and 4 only.Rate this question:

It is a communication channel whose direction of transmission is unchanging.
- A.
Fixed channel
- B.
Half channel
- C.
Full channel
- D.
Simplex channel
Correct Answer
D. Simplex channelExplanation
A simplex channel is a communication channel where the direction of transmission is unchanging. In this type of channel, information can only flow in one direction, from the sender to the receiver. It does not allow for two-way communication or simultaneous transmission in both directions. This type of channel is commonly used in broadcast systems, where information is transmitted from a central source to multiple receivers.Rate this question:

This involves the concept of routes, wherein a message sent on the network can take any ofseveral possible paths by “hopping” from node to node until the destination is reached.
- A.
Mesh Network Topology
- B.
Ring Network Topology
- C.
Tree Network Topology
- D.
Star Network Topology
Correct Answer
A. Mesh Network TopologyExplanation
Mesh Network Topology involves the concept of routes, wherein a message sent on the network can take any of several possible paths by "hopping" from node to node until the destination is reached. In a mesh network, each node is connected to every other node, creating a highly redundant and fault-tolerant network. This topology is commonly used in wireless networks where devices can communicate directly with each other without the need for a central access point. It allows for efficient and reliable communication as messages can be rerouted if a node or path fails.Rate this question:

A bus network may not work well if the nodes are located at scattered points that do not lienear a common line.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
A bus network relies on nodes being located along a common line to efficiently transmit data or communicate. If the nodes are scattered and not linearly aligned, it can lead to longer transmission distances and increased latency. This can result in poor performance and reduced effectiveness of the bus network. Therefore, the statement that a bus network may not work well if the nodes are located at scattered points that do not lie near a common line is true.Rate this question:

- A.
True
- B.
False
Correct Answer
A. TrueExplanation
A record is indeed one complete set of fields. In a database or spreadsheet, a record represents a single entity or item, and it contains all the relevant information about that entity in the form of fields. These fields can include attributes such as name, age, address, and so on. Therefore, the statement "Record is one complete set of fields" is true because a record encompasses all the necessary data for a specific entity.Rate this question:

Broadcast networks is a type of transmission technology which consist of many connectionsto individual pairs of machines
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Broadcast networks are a type of transmission technology that allows information to be sent from one source to multiple destinations simultaneously. In broadcast networks, there is a single channel through which all the connected machines receive the transmitted data. This is different from point-to-point networks where each pair of machines has its own dedicated connection. Therefore, the given statement is false as broadcast networks do not consist of many connections to individual pairs of machines.Rate this question:

Printing pay cheques and updating the payroll register are example transactions ofComputer-based Payroll System
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Printing pay cheques and updating the payroll register are indeed example transactions of a computer-based payroll system. In a computer-based payroll system, pay cheques are generated and printed using software that calculates the wages and deductions for each employee. The payroll register is then updated to record the payment details and maintain accurate records of employee salaries, taxes, and other deductions. These tasks are efficiently and accurately performed by computer-based systems, making them essential components of payroll management.Rate this question:

Transmitter is a pathway over which information can be transferred
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is incorrect. A transmitter is not a pathway over which information can be transferred. Rather, a transmitter is a device or equipment that is used to send information or signals to a receiver through a medium such as air or cables. It converts the information into a suitable form for transmission and then sends it over the medium. Therefore, the correct answer is False.Rate this question:
