What type of communication network is used to communicate from one city to another?
Hide Answer
Answer:
WAN
Explanation:
A WAN (Wide Area Network) is used to communicate from one city to another. Unlike LAN (Local Area Network) and MAN (Metropolitan Area Network) which are limited to a specific area, WAN covers a larger geographical area, connecting multiple cities or even countries. It utilizes various technologies such as leased lines, satellite links, or internet connections to establish communication between distant locations. Therefore, WAN is the correct answer as it specifically addresses communication between cities.

What is the base of a number system called?
Hide Answer
Answer:
Radix
Explanation:
The correct answer is "Radix". In every number system, there is a base or radix which determines the number of unique digits used and the value of each digit. For example, in the decimal system, the radix is 10 because there are 10 unique digits (0-9). Similarly, in the binary system, the radix is 2 because there are only 2 unique digits (0 and 1). The radix is essential in understanding and interpreting numbers in different number systems.

Which part of the computer performs arithmetic and logical operations?
Hide Answer
Answer:
Arithmetic Logic Unit
Explanation:
The correct answer is the Arithmetic Logic Unit. The Arithmetic Logic Unit (ALU) is responsible for performing arithmetic operations (such as addition, subtraction, multiplication, and division) as well as logical operations (such as AND, OR, and NOT) in a computer system. It is a crucial component of the central processing unit (CPU) and is responsible for executing the instructions of a program by manipulating data and making decisions based on logical conditions.

15.
Which protocol is used to retrieve email from a mail server?
Hide Answer
Answer:
IMAP
Explanation:
IMAP is a protocol used by email clients to retrieve emails from a mail server. Unlike POP (Post Office Protocol), which downloads the email and usually removes it from the server, IMAP allows the email to remain on the server while providing access to it across multiple devices. This is particularly useful when users access their email from multiple locations, such as a phone, laptop, and desktop, because any actions performed on the email (such as reading, deleting, or moving) are synchronized across all devices. IMAP essentially keeps a copy of the email on the server, allowing for better flexibility in managing emails.

16.
What does 'SQL' stand for in database management?
Hide Answer
Answer:
Structured Query Language
Explanation:
SQL, or Structured Query Language, is a specialized programming language used to communicate with relational databases. It is the industry-standard language for querying, manipulating, and defining data in a database. SQL enables users to retrieve specific data, insert new records, update existing records, and delete records from a database. It also allows users to create and modify database structures (like tables) and set permissions for accessing the data. SQL is powerful because it is a declarative language, meaning that users specify what they want to do with the data, and the system decides how to do it, abstracting the complexity of managing large amounts of data.

In which year was the first hard disk drive introduced?
Hide Answer
Answer:
1956
Explanation:
In 1956, IBM introduced the first hard disk drive (HDD), known as the IBM 350. This was part of the IBM 305 RAMAC system, and it marked a significant advancement in data storage technology. The IBM 350 could store about 3.75 megabytes of data, which was substantial at the time. It used magnetic disks to store data, which could be accessed quickly and reliably. The drive consisted of fifty 24-inch disks and was enormous compared to modern storage devices. However, it laid the foundation for modern HDDs, which have since become smaller, more reliable, and capable of storing terabytes of data.

What is the main function of the ALU (Arithmetic Logic Unit)?
Hide Answer
Answer:
Perform Calculations
Explanation:
The Arithmetic Logic Unit (ALU) is a fundamental part of the CPU responsible for carrying out arithmetic and logical operations. Arithmetic operations include basic math like addition, subtraction, multiplication, and division. Logical operations involve comparing two numbers and determining if one is greater than, less than, or equal to the other. The ALU receives instructions from the control unit of the CPU and performs these operations on data stored in the computer’s memory. It is crucial for the overall functioning of a computer because it handles all mathematical computations and logical decisions required by applications and the operating system.

What is the term for the smallest unit of data in a computer system?
Hide Answer
Answer:
Bit
Explanation:
A bit, short for binary digit, is the smallest unit of data in a computer system. It can have only one of two values: 0 or 1, which correspond to the two states of a digital system (off or on, respectively). Bits are used in combination to represent more complex data. For example, a group of 8 bits forms a byte, which is used to represent a single character of text. In digital communication and computing, bits are fundamental because they represent the underlying data that all digital information is built upon. Large amounts of data, such as files, images, or videos, are stored as collections of bits.

Which programming language is known for its use in artificial intelligence?
Hide Answer
Answer:
LISP
Explanation:
LISP, or List Processing, is one of the oldest programming languages still in use, created in 1958. It was designed for artificial intelligence (AI) development and is known for its unique syntax based on lists. LISP is especially suited for symbolic reasoning, which is crucial in AI because it allows for the manipulation of symbols rather than just numbers. LISP supports recursion and dynamic data structures, both of which are important for solving complex AI problems. It has been used in areas like machine learning, natural language processing, and expert systems, which rely on its flexibility and powerful symbolic computation capabilities.

22.
In the computer memory hierarchy, which is the fastest memory type?
Hide Answer
Answer:
Cache
Explanation:
Cache memory is the fastest type of memory in a computer and is used to store frequently accessed data and instructions. Cache is located close to the CPU, either directly on the processor (L1 cache) or on the motherboard (L2/L3 cache). The speed of cache memory allows the CPU to access data much more quickly than if it had to retrieve it from the main memory (RAM). Cache is particularly useful for speeding up repetitive tasks because it keeps recently used data close at hand. However, it is small in size compared to RAM, so it is used only for critical data that needs to be accessed quickly.

What is the purpose of DNS in the internet structure?
Hide Answer
Answer:
Translate Domain Names
Explanation:
The Domain Name System (DNS) is the technology that translates human-readable domain names, such as www.example.com, into the numerical IP addresses that computers use to identify each other on the network. DNS is often compared to a phonebook because it allows users to access websites using easy-to-remember names instead of complicated numerical addresses. Without DNS, users would have to remember the exact IP address of every website they wanted to visit. The DNS system is distributed globally, with many DNS servers working together to provide quick and reliable access to websites.

What type of software controls a computer's hardware and provides a platform for applications?
Hide Answer
Answer:
Operating System
Explanation:
An operating system (OS) is a type of system software that acts as an intermediary between the computer hardware and the user. It manages all hardware resources, such as the CPU, memory, storage, and input/output devices, and provides an environment for applications to run. The OS handles tasks such as file management, process scheduling, and security. Common operating systems include Microsoft Windows, macOS, and Linux. Without an operating system, users would not be able to interact with the computer in a meaningful way because there would be no way to run software applications or manage hardware components effectively.
