What is the most widely used character encoding standard today?
The ASCII (American Standard Code for Information Interchange) character set uses 7-bit units, with a trivial encoding designed for 7-bit bytes. It is the most important character set in use today, despite its limitation to very few characters, because its design is the foundation for most modern character sets.
What is the term for two or more independent processors within a system unit?
Multicore processor. A new type of chip that provides two or more separate and independent CPUs. Parallel processing.
Which of the following is a function of the control unit quizlet?
Which of the following is a function of the control unit? It directs the movement of electronic signals between memory and the arithmetic-logic unit.
Are portable and much smaller than desktops with the keyboard and pointing device as part of the system unit?
Desktop system units that are placed vertically are sometimes referred to as a tower unit or tower computer. Although typically not as powerful as desktops, laptops are portable and much smaller. Their system units are housed with selected secondary storage devices and input devices (keyboard and pointing device).
What is encoding =’ UTF-8?
UTF-8 is a Unicode character encoding method. This means that UTF-8 takes the code point for a given Unicode character and translates it into a string of binary. It also does the reverse, reading in binary digits and converting them back to characters.
Is ASCII the same as UTF-8?
For characters represented by the 7-bit ASCII character codes, the UTF-8 representation is exactly equivalent to ASCII, allowing transparent round trip migration. Other Unicode characters are represented in UTF-8 by sequences of up to 6 bytes, though most Western European characters require only 2 bytes3.
What is a CPU unit?
The computer's central processing unit (CPU) is the portion of a computer that retrieves and executes instructions. The CPU is essentially the brain of a CAD system. It consists of an arithmetic and logic unit (ALU), a control unit, and various registers. The CPU is often simply referred to as the processor.
Where is the memory management unit placed state the use of it?
The MMU is usually located within the computer's central processing unit (CPU), but sometimes operates in a separate integrated chip (IC). All data request inputs are sent to the MMU, which in turn determines whether the data needs to be retrieved from RAM or ROM storage.
What is the function of control unit subsystem in a computer?
The control unit of the central processing unit regulates and integrates the operations of the computer. It selects and retrieves instructions from the main memory in proper sequence and interprets them so as to activate the other functional elements of the system at the appropriate moment…
Which of the following is a popular mobile operating system?
The most well-known mobile OSs are Android, iOS, Windows phone OS, and Symbian. The market share ratios of those OSs are Android 47.51%, iOS 41.97%, Symbian 3.31%, and Windows phone OS 2.57%. There are some other mobile OSs that are less used (BlackBerry, Samsung, etc.)
Which type of computer is the most common use?
Microcomputers. A microcomputer, also known as a personal computer, is designed to be used by one user at a time. The term microcomputer relates to the microprocessor that is used for the purpose of processing data and instruction codes. These are the most common computer types since they are not very expensive.
Which of the following computer is smallest in term of form factor and size?
Microcomputers are the smallest, least expensive and the most used types of computers.
Why is UTF-8 popular?
UTF-8 is currently the most popular encoding method on the internet because it can efficiently store text containing any character. UTF-16 is another encoding method, but is less efficient for storing text files (except for those written in certain non-English languages).
What is UTF-16 encoding?
UTF-16 is an encoding of Unicode in which each character is composed of either one or two 16-bit elements. Unicode was originally designed as a pure 16-bit encoding, aimed at representing all modern scripts.
Is UTF-16 same as Unicode?
UTF-16 is an encoding of Unicode in which each character is composed of either one or two 16-bit elements. Unicode was originally designed as a pure 16-bit encoding, aimed at representing all modern scripts.
Why is UTF-8 used?
Why use UTF-8? An HTML page can only be in one encoding. You cannot encode different parts of a document in different encodings. A Unicode-based encoding such as UTF-8 can support many languages and can accommodate pages and forms in any mixture of those languages.
What mean GPU?
Graphics processing unit Graphics processing unit, a specialized processor originally designed to accelerate graphics rendering. GPUs can process many pieces of data simultaneously, making them useful for machine learning, video editing, and gaming applications.
What is CPU and GPU?
CPU (central processing unit) is a generalized processor that is designed to carry out a wide variety of tasks. GPU (graphics processing unit) is a specialized processing unit with enhanced mathematical computation capability, ideal for computer graphics and machine-learning tasks.
What is the MMU used for?
An important function of the Memory Management Unit (MMU) is to enable the system to run multiple tasks, as independent programs running in their own private virtual memory space.
What is meant by MMU?
A memory management unit (MMU) is a computer hardware component that handles all memory and caching operations associated with the processor.
Which subsystem of a computer is responsible for the sending of signals to other subsystems?
input/output subsystem The input/output subsystem allows the computer to communicate with the outside world, including archival storage for information the system needs. Input/output devices vary widely: keyboard, mouse, monitor, printer, hard drive, tape storage, etc. Each has different modes of communication.
What is the role of control unit and ALU in performing computer operations?
The control unit tells the ALU what operation to perform on that data, and the ALU stores the result in an output register. The control unit moves the data between these registers, the ALU, and memory.
Which is the most widely used operating system?
Microsoft Windows Microsoft Windows. Microsoft Windows is one of the popular operating system types and is preloaded on most new PC hardware.
Is the most widely used mobile operating system in the United States?
| Mobile Operating Systems | Percentage Market Share |
|---|---|
| Mobile Operating System Market Share in United States Of America – June 2022 | |
| iOS | 56.69% |
| Android | 43.02% |

Which type of computer is used today?
Personal computers A PC or microcomputer uses a single chip (microprocessor) for its central processing unit (CPU). “Microcomputer” is now primarily used to mean a PC, but it can refer to any kind of small computer, such as a desktop computer, laptop computer, tablet, smartphone, or wearable.
What is ascii code where is it used and why?
ASCII, in full American Standard Code for Information Interchange, a standard data-encoding format for electronic communication between computers. ASCII assigns standard numeric values to letters, numerals, punctuation marks, and other characters used in computers.
What is the most common type of computer?
Microcomputers. A microcomputer, also known as a personal computer, is designed to be used by one user at a time. The term microcomputer relates to the microprocessor that is used for the purpose of processing data and instruction codes. These are the most common computer types since they are not very expensive.
Which of the following computers are lower than mainframe computers in terms of speed and storage capacity?
Mini computers Explanation: The answer is a. Mini computers are compared to mainframe computers in terms of: 1. speed and, 2.
Is ASCII or UTF-8 more efficient?
There is absolutely no difference in this case; UTF-8 is identical to ASCII in this character range. If storage is an important consideration, maybe look into compression. A simple Huffman compression will use something like 3 bits per byte for this kind of data.
Is UTF-32 used?
The only UTF32 is fixed-width and unfortunately, no one uses it. Also, worth knowing is that Java Strings are represented using UTF-16 bit characters, earlier they use USC2, which is fixed width.
