Accepted Answer

The processor is also known as the central processing unit (CPU) and is responsible for interpreting and carrying out the basic instructions that operate the computer. It is considered the "brain" of the computer. The motherboard is a circuit board that connects all the components of the computer, but it does not interpret or carry out instructions. The control unit is also a part of the CPU, but its function is to manage the flow of data within the CPU. The arithmetic unit is another part of the CPU that performs mathematical operations, but it is not responsible for interpreting or carrying out instructions.

Question 3

B)supercomputers
C)mainframes
D)mobile devices

Accepted Answer

Mainframes are specifically designed to handle large amounts of data and multiple users simultaneously. They are known for their reliability, security, and scalability, and are commonly used by enterprises and government organizations for critical applications such as financial transactions, batch data processing, and airline reservation systems. Supercomputers are also powerful computers, but they are typically used for specialized tasks such as scientific simulations, modeling, and data analysis. Embedded computers are small, low-power devices that are built into other products or systems, while mobile devices are portable computing devices such as smartphones and tablets.

Question 4

Question 5

Which of the following exists in the form of a single circuit board?
A)rack server
B)tower server
C)blade server
D)bay server

Accepted Answer

Blade servers are designed to be more compact than rack or tower servers, and they typically consist of a single circuit board. Bay servers are a type of blade server, but they are designed to be inserted into a blade enclosure. Rack servers and tower servers often have multiple circuit boards and are not typically designed to be as compact as blade servers.

Choice A, memory manager, refers to a software component that manages a computer's memory resources. Choice B, CP case, is not a commonly used term in the context of computers. Choice D, encapsulator, is not a commonly used term in the context of computer hardware.

Question 7

Which of the following do most major corporations use for business activities like billing millions of customers, preparing payroll for thousands of employees, and managing millions of items in inventory?
A)embedded computers
B)supercomputers
C)mainframes
D)mobiles devices

Accepted Answer

Mainframes are typically used for large-scale computing tasks that require high levels of security, reliability, and processing power. They can handle millions of transactions and store vast amounts of data, making them well-suited for tasks like billing, payroll, and inventory management for major corporations. Embedded computers and mobile devices are generally not powerful enough to handle these types of tasks, while supercomputers are typically used for specialized scientific applications.

Question 8

-Which of the following is the practice of sharing computing resources, such as servers, like those in the accompanying figure?
A)clustering
B)concatenation
C)aggregation
D)virtualization

Accepted Answer

Question 10

-Which of the following is not a part of a server like the one in the accompanying figure?
A)processor
B)network connections
C)storage
D)bundled software

Accepted Answer

Bundled software is not a physical component of a server; it refers to software that may come pre-installed or included with the server, but it is not a part of the server's hardware.

Question 11

Which of the following is an example of an operating system?
A)C++
B)C#
C)Windows
D)Visual Basic

Accepted Answer

Windows is an example of an operating system, as it is a software program that manages computer hardware and software resources, provides common services for computer programs, and allows applications to run on the computer system.

The other choices, C++, C#, and Visual Basic, are programming languages and not operating systems.

Which of the following terms includes speakers, webcams, and printers as examples?
A)peripherals
B)integrated systems
C)ports
D)embedded computers

Accepted Answer

Peripherals are external devices that can be connected to a computer, and speakers, webcams, and printers are all examples of peripherals. Integrated systems refer to a combination of hardware and software components, ports are the connection points for peripherals and other devices, and embedded computers are small computing systems embedded into larger devices.

Question 14

Which of the following are the fastest, most powerful computers - and the most expensive?
A)desktop computers
B)notebook computers
C)midrange servers
D)supercomputers

Accepted Answer

Supercomputers are the fastest and most powerful computers, capable of performing complex calculations and processing vast amounts of data quickly. They are also the most expensive, often costing millions of dollars to build and maintain. Desktop and notebook computers are not as powerful as supercomputers, and midrange servers are designed for specific business needs rather than high-performance computing.
