Each process can be defined by the portion of memory that contains the program which is being executed by the process (along with its associated data), and by the contents of the Central Processing Unit (CPU) registers used by the process.. Each process also alternates between processor usage and input/output (I/O) event occurrences. The latter could wait for an I/O to be performed or for some other external event to occur. The processor will execute one process at a time, but will switch to another process, if the latter is waiting for an event. The processor will thus be kept busy by executing a specific process, while all other system processes are in queue (either for the processor or for an
Imperative programming is the cornerstone of computing. CPUs primarily work as imperative execution engines, and compilers translate into this language. As the primary way of driving computers for most of our programming history, it's well represented in the language arena. > I'm not saying all of computing works this way. A
They can be the engineers, accountants, manager, customers, and so on. Most of us are information system end user because it must use the system to get and collect the information. Information System (IS) specialist is the people actually create or develop and operate the information system. In IS specialist include system analyst, programmers, testers, technical, computer operator, and so on. The tasks do by the system analyst are design information system based on the information requirements of end uses, computer operators operate large computer system, and programmers prepare computer programs based on the specifications of system
OPERATING SYSTEMS An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. The operating system organizes and controls the hardware and is the piece of software that converts the collection of hardware blocks into a powerful computer tool. In general terms, the tasks of the operating system are: 1. The main tasks in processor management are to ensure that each process and application receives enough processor time to function properly, using maximum processor cycles for a real job as possible and switching between processes in a multitasking environment. 2.
Operating system is a system software that is manages a computer hardware and a computer software provides resources and a common service of computer programs. Operating system provides all computer program and other devise including firmware to perform any function. Time sharing is an operating system that perform schedule task for used the system this may include various types of software such as accounting software that is used for the cost allocation time of processor mass storage printing and other resources. Computer Hardware function inputs and outputs and memory allocations operating system acts between computer program and computer hardware these applications code usually executed directly the computer hardware and frequently
The first one is software engineering. It is concerned with maintaining and developing software systems making sure that their programs run efficiently. You can get in this field while also having a degree in the computer science, although, our main focus right now is on computer engineering. Software engineers use their math skills and the theory of computers to develop new software. Computer software engineers can be into two categories: applications engineers and systems engineers.
Dandamudi (2005) stated that Assembly language are directly affected by the instruction set and processor architecture. However, Gaonkar (2002) mentioned that Assembly language uses symbolic code to represent each instruction. He also added that the mnemonic for a particular instruction include words that suggest the operation to be performed by that command. According to Seaver (n.d.), Assembly language refers to a simplistic encoding of computer code into something that can be identified with human. Assembly language must be processed by a program in order to produce the computer language code (Dandamudi, 2005).
Its research goal is to use the machine, usually electronic equipments, computers and so on, as much as possible to simulate the activities of the human spirit, and strive to improve and to reach human capacity in these areas. Its field of study and range of applications are very wide, such as automatic theorem proving, reasoning, pattern recognition, expert knowledge systems, intelligent robots, learning, gaming, natural language understanding, etc. Pattern recognition may be the most basic and the most important discipline of artificial intelligence. In short, pattern recognition is to allow computers to understand the things around it so that our communication with the computer more natural and convenient. It includes character recognition (reading), speech recognition (listening), speech synthesis (say), natural language understanding and computer pattern recognition.
The data from primary storage tends to go away after the computer is turned off. When a user activates a program on a computer, data is moved from secondary storage devices into the RAM and cache of primary storage in order for the computer to actually use
Software also allows the hardware to process the data for the user. However, it is important to know and understand that there is a distinct difference between hardware and software. Software is an intangible resource and it cannot be held in our hands meanwhile hardware consists of tangible resources such as a mouse, keyboards, USB ports, CPUs, memory, printers, and etc. Hardware and software need to work together in order to make a system fully
