A computer is a device that is programmed to perform certain mathematical or logical operations automatically, without human supervision. Modern computers are able to execute a wide array of tasks called programs. These programs allow computers to do a wide assortment of tasks. Some examples of computer programs are word processors, spreadsheets, operating systems, databases, and web browsers. The computer hardware, which includes mainboards, input and output devices such as printers and keyboards, memory devices such as hard drives and random access memory (RAM) all collectively form a central processing unit (CPU) of the computer.
A computer’s CPU is the center of the computer. The computer hardware stores the instructions and data that are fed into programs through the CPU. The computer hardware also controls the execution of the program in turn. The computer software controls the operation of the computer and is stored on memory in the form of instructions, options, and data. The computer hardware stores programs and data in a memory that can access by the CPU. A typical computer has four to eight sockets for connecting external hardware such as a printer or scanner.
Computers have many layers; the inner layers are instruction processors. The application software installed on the desktop has the job of running the main frame computer that connects the input and output devices, processing messages, and performing any other tasks needed by the user. The output from the main frame computer is displayed on the monitor or in a browser.
Many computer systems are designed for simple, singular tasks like word processing or simple data entry. However, in the past, the computer system was designed for the creation of large scale, complex programs such as operating systems, databases, and web applications. Computer engineers, who specialize in software development, are often called upon to develop specific computer systems for specific businesses or industries.
Computer software developers write the code that allows a computer to carry out a specific set of commands. The computer engineers then convert the written code into machine instructions that are carried out by the appropriate hardware. Most commonly, computer engineers are responsible for the creation and maintenance of a computer system that allows a business to process large amounts of information.
One of the most popular computer engineering degree fields is the information systems manager, or IT Manager, who works mainly in the areas of hardware, networking, memory, and input/output devices. This field requires great attention to detail and a general knowledge of technology. A Bachelor’s degree in this area will provide you with the necessary skills to become one of the most sought after professionals in your field. As you enter the workforce, most major employers require a minimum GPA of 3.0 in order to apply. These professionals often begin their careers with a temporary position and later find permanent positions at larger companies.
