The feature that distinguishes a LAN from a WAN is that (D) "a LAN connects computers in a single location".

A LAN (Local Area Network) is a computer network that connects devices in a small geographical area, such as a home, office, or building. In contrast, a WAN (Wide Area Network) is a network that covers a larger geographical area, such as a city, country, or even the whole world. The main difference between the two is the size of the area they cover and the number of devices they connect. LANs typically have higher bandwidth and faster data transfer rates, while WANs often have lower bandwidth and slower transfer rates due to the distance between devices. Both LANs and WANs can be used to share resources and data, but they are designed to meet different needs.

Therefore, the correct answer is (D) "A LAN connects computers in a single location."

The most distinguishing feature of the use of a client-server processing model over an old mainframe configuration is the distribution of computing power.

A client-server processing model is a distributed application structure that partitions tasks or workload between service providers and service requesters, called clients. Each computer in the client-server model operates as either a client or a server. The server provides services to the clients, such as data sharing, data manipulation, and data storage.

The client requests services from the server, allowing for the distribution of processing responsibilities between the two entities. In this model, the server is responsible for storing data, while the client is responsible for data retrieval. A mainframe configuration is an older computing model that is centralized, where the mainframe performs all computing activities.

All users are linked to the mainframe, which stores all data and applications, as well as handles all processing responsibilities. Mainframes can handle a large amount of data and have a lot of processing power, but they are inflexible and can be difficult to scale. The distribution of computing power is the most distinguishing feature of the use of a client-server processing model over an old mainframe configuration.

By utilising the idea of normalisation, a "base" (or database) in a database enables you to store only one version of the data.

Database design uses the normalisation process to reduce redundancy and enhance data integrity. It entails decomposing a database into smaller, more manageable tables and creating connections among them. Each item of data is therefore kept in a single location, and all references to that data are made of that location alone. This makes the database more effective and simpler to administer by reducing data redundancy and enhancing data consistency. There are different levels of normalisation, and each has its own specifications on how to arrange data. The end result of normalising is to produce a database that is dependable and simple to use, resulting in more consistent and efficient data administration.

Some trojan horses contain a virus or a worm, which can replicate and spread. Virus experts call this a blended threat because it combines more than one type of malicious code.

A blended threat is a combination of computer viruses, worms, and Trojan horses. Blended threats usually exploit security vulnerabilities or software bugs to spread rapidly through networks. Blended threats can be engineered to create a distributed denial of service (DDoS) attack or to provide remote control over your system to attackers. In most cases, blended threats require no human interaction to spread, so they may infect computer systems or networks before users are aware of their presence. Because of their stealthy nature, blended threats can often evade the most sophisticated intrusion detection systems (IDS) and intrusion prevention systems (IPS).

The given statement "c does not perform array bounds checking, making it possible for you to assign a pointer the address of an element out of the boundaries of an array" is TRUE.

The array is the set of values of the same data type that can be stored sequentially in memory using a single name. You can consider it as a set of containers that hold a particular type of data with a unique name. For example, an array can store ten values of the int data type. However, it is a bit of a double-edged sword.

On one hand, the array can improve the efficiency of the program's operation, and on the other hand, it can also put the system in danger if not used correctly. One example of it is array bounds checking.

Most programming languages that support arrays perform bounds checking to ensure that the array is only accessed within the bounds of the memory allocated for it. However, in the case of C, it does not perform any such checks, and if you try to access an array's elements beyond its bounds, it will generate an error.

It is also possible to assign a pointer the address of an element out of the boundaries of an array in C. However, the program will not check whether the address is in the array boundaries or not. It can cause a variety of errors, including program crashes or security vulnerabilities.
