What is the correct sequence of computer?
The correct answer is Fetch instruction, Decode instruction, Read operands, Execute instruction and Store data.
What is the boot sequence of PC?
Boot sequence is the order in which a computer searches for nonvolatile data storage devices containing program code to load the operating system (OS). Typically, a Macintosh structure uses ROM and Windows uses BIOS to start the boot sequence.
What are BIOS in computer?
As your PC’s most important startup program, BIOS, or Basic Input/Output System, is the built-in core processor software responsible for booting up your system. Typically embedded into your computer as a motherboard chip, the BIOS functions as a catalyst for PC functionality action.
What is sequence in coding?
Sequences are the main logical structure of algorithms or programs. When creating algorithms or programs, the instructions are presented in a specific correct order. A sequence can contain any number of instructions but each instruction must be run in the order they are presented.
What is the sequence of computer memory?
In computing, sequential access memory (SAM) is a class of data storage devices that read stored data in a sequence. This is in contrast to random access memory (RAM) where data can be accessed in any order. Sequential access devices are usually a form of magnetic storage or optical storage.
What are the fundamental sequence of all computers?
Step 1 − Takes data as input. Step 2 − Stores the data/instructions in its memory and uses them as required. Step 3 − Processes the data and converts it into useful information. Step 4 − Generates the output.
What are the steps of the boot process?
Although it is possible to break down the boot-up process using a highly detailed analytical methodology, many computer professionals consider the boot-up process to consist of five significant steps: power on, POST, load BIOS, operating system load, and transfer of control to the OS.
What are the four main parts of the boot process?
The Boot Process
- Initiate filesystem access.
- Load and read configuration file(s)
- Load and run supporting modules.
- Display the boot menu.
- Load the OS kernel.
What is CMOS full form?
Complementary metal–oxide–semiconductor (CMOS, pronounced “see-moss”), also known as complementary-symmetry metal–oxide–semiconductor (COS-MOS), is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for …
What are the four functions of a BIOS?
The 4 functions of BIOS
- Power-on self-test (POST). This tests the hardware of the computer before loading the OS.
- Bootstrap loader. This locates the OS.
- Software/drivers. This locates the software and drivers that interface with the OS once running.
- Complementary metal-oxide semiconductor (CMOS) setup.
What is a sequence in programming example?
Sequence is the default control structure; instructions are executed one after another. They might, for example, carry out a series of arithmetic operations, assigning results to variables, to find the roots of a quadratic equation ax2 + bx + c = 0.
What are the theoretical aspects of Computer Science?
Theoretical computer science ( TCS) is a subset of general computer science that focuses on mathematical aspects of computer science such as the theory of computation, lambda calculus, and type theory . It is difficult to circumscribe the theoretical areas precisely.
What is the duality view of Computer Science?
A programmer designs algorithms, intended for mechanical execution, intended to control existing or conceivable computer equipment. (Dijkstra 1974: 1) On the duality view, computer science is not an abstract mathematical discipline that is independent of the physical world. To be used, these things must have physical substance.
Which is true of the philosophy of Computer Science?
Computational systems are widespread in everyday life. Their design, development and analysis are the proper object of study of the discipline of computer science. The philosophy of computer science treats them instead as objects of theoretical analysis. Its first aim is to define such systems, i.e., to develop an ontology of computational systems.
Why is computer science considered an exact science?
Computer programming is an exact science in that all the properties of a program and all the consequences of executing it in any given environment can, in principle, be found out from the text of the program itself by means of purely deductive reasoning.
