A computer program in its human-readable form is called source code. Source code needs another computer program to execute because computers can only execute their native machine instructions. Therefore, source code may be translated to machine instructions using the language's compiler. (Assembly language programs are translated using an assembler.) The resulting file is called an executable. Alternatively, source code may execute within the language's interpreter.[2]
Computers manufactured until the 1970s had front-panel switches for manual programming.[27] The computer program was written on paper for reference. An instruction was represented by a configuration of on/off settings. After setting the configuration, an execute button was pressed. This process was then repeated. Computer programs also were automatically inputted via paper tape, punched cards or magnetic-tape. After the medium was loaded, the starting address was set via switches, and the execute button was pressed.[27]

COBOL (1959) stands for "COmmon Business Oriented Language." Fortran manipulated symbols. It was soon realized that symbols did not need to be numbers, so strings were introduced.[54] The US Department of Defense influenced COBOL's development, with Grace Hopper being a major contributor. The statements were English-like and verbose. The goal was to design a language so managers could read the programs. However, the lack of structured statements hindered this goal.[55]
However, the Basic syntax was too simple for large programs.[7] Recent dialects added structure and object-oriented extensions. Microsoft's Visual Basic is still widely used and produces a graphical user interface.[6]
Writing large, reliable, and readable Lisp programs requires forethought. If properly planned, the program may be much shorter than an equivalent imperative language program.[75] Lisp is widely used in artificial intelligence. However, its usage has been accepted only because it has imperative language operations, making unintended side-effects possible.[77]
Modular programming is a technique to refine imperative language programs. Refined programs may reduce the software size, separate responsibilities, and thereby mitigate software aging. A program module is a sequence of statements that are bounded within a block and together identified by a name.[114] Modules have a function, context, and logic:[115]
Computer programs may be categorized along functional lines. The main functional categories are application software and system software. System software includes the operating system, which couples computer hardware with application software.[120] The purpose of the operating system is to provide an environment where application software executes in a convenient and efficient manner.[120] Both application software and system software execute utility programs. At the hardware level, a microcode program controls the circuits throughout the central processing unit.
The term operating system may refer to two levels of software.[129] The operating system may refer to the kernel program that manages the processes, memory, and devices. More broadly, the operating system may refer to the entire package of the central software. The package includes a kernel program, command-line interpreter, graphical user interface, utility programs, and editor.[129]
A utility program is designed to aid system administration and software execution. Operating systems execute hardware utility programs to check the status of disk drives, memory, speakers, and printers.[138] A utility program may optimize the placement of a file on a crowded disk. System utility programs monitor hardware and network performance. When a metric is outside an acceptable range, a trigger alert is generated.[139]
Utility programs include compression programs so data files are stored on less disk space.[138] Compressed programs also save time when data files are transmitted over the network.[138] Utility programs can sort and merge data sets.[139] Utility programs detect computer viruses.[139]
FNS works to end hunger and obesity through the administration of 16 federal nutrition assistance programs including WIC, Supplemental Nutrition Assistance Program and school meals. In partnership with state and tribal governments, our programs serve one in four Americans during the course of a year.
OFAC administers a number of different sanctions programs. The sanctions can be either comprehensive or selective, using the blocking of assets and trade restrictions to accomplish foreign policy and national security goals.
HUD's programs and related topics support HUD's priorities across a range of policy areas including Affordable Housing Development and Preservation, Community and Economic Development, Environment and Energy, Fair Housing, Homelessness, Homeownership, Rental Assistance, and Supportive Housing and Services.
The Grazing Lands Conservation Initiative (GLCI) was developed as a coordinated effort to identify priority issues, find solutions, and effect change on private grazing land, enhancing existing conservation programs.
The J-1 Visa provides countless opportunities for international candidates looking to travel and gain experience in the United States. The multifaceted programs enable foreign nationals to come to the U.S. to teach, study, conduct research, demonstrate special skills or receive on the job training for periods ranging from a few weeks to several years.
An accredited universityAll ASU undergraduate and graduate academic programs are fully accredited by the Higher Learning Commission. Many programs also have additional accreditation through specialized accrediting agencies.
The EBCCP (formerly RTIPs) website is a searchable database of evidence-based cancer control programs and is designed to provide program planners and public health practitioners easy and immediate access to program materials.
This optional funding opportunity allows states and territories to apply for up to 2.5 percent of their total allocations from each of the two Home Energy Rebates programs, capped at $2.5 million, or $5 million total. The amount that states and territories receive in early administrative funds will be subtracted from the allocation received from the full funding amount described above.
VA helps Veterans, Servicemembers, and eligible surviving spouses become homeowners. As part of our mission to serve you, we provide a home loan guaranty benefit and other housing-related programs to help you buy, build, repair, retain, or adapt a home for your own personal occupancy.
While the IRS manages the VITA and TCE programs, the VITA/TCE sites are operated by IRS partners and staffed by volunteers who want to make a difference in their communities. The IRS-certified volunteers who provide tax counseling are often retired individuals associated with non-profit organizations that receive grants from the IRS.
Founded in 1989 by inventor Dean Kamen, FIRST is a global nonprofit organization that prepares young people for the future through a suite of life-changing youth robotics programs that build skills, confidence, and resilience.
Project-based, hands-on FIRST programs introduce students to engineering and coding in engaging, inclusive, and creative learning environments, where students work collaboratively to solve themed robotics challenges.
This Executive order established two new programs and modified another. They are the Internship Program for current students; the Recent Graduates Program for people who have recently graduated from qualifying educational institutions or programs (2 years from the date the graduate completed an academic course of study); and the reinvigorated Presidential Management Fellows (PMF) Program for people who obtained an advanced degree (e.g., graduate or professional degree) within the preceding two years. These programs, collectively the Pathways Programs, are streamlined developmental programs tailored to promote employment opportunities for students and recent graduates in the Federal workforce.
As directed by the Executive order, OPM issued a final Pathways Rule to implement these programs. The final rule aims to improve recruiting efforts, offer clear paths to Federal internships for students from high school through post-graduate school and to careers for recent graduates, and to provide meaningful training and career development opportunities for individuals who are at the beginning of their Federal service.
The Student Educational Employment Program provides Federal employment opportunities to students who are enrolled or accepted for enrollment as degree seeking students taking at least a half-time academic, technical, or vocational course load in an accredited high school, technical, vocational, 2 or 4 year college or university, graduate or professional school. The Student Educational Employment Program established December 16, 1994, is a streamlined program which replaces the old Federal Student Employment Program by consolidating four programs:
The Recent Graduates Program affords developmental experiences in the Federal Government intended to promote possible careers in the civil service to individuals who have recently graduated from qualifying educational institutions or programs. To be eligible, applicants must apply within two years of degree or certificate completion (except for veterans precluded from doing so due to their military service obligation, who have up to six years after degree completion to apply). Successful applicants are placed in a dynamic, developmental program with the potential to lead to a civil service career in the Federal Government. The program lasts for 1 year (unless the training requirements of the position warrant a longer and more structured training program). Here are some key provisions of the Recent Graduates Program.
On September 27, 2023, the U.S. Department of Education awarded approximately $235.8 million in new funds through 29 grants in three CSP programs, CSP State Entity Grants, CSP Developer Grants, and CSP Credit Enhancement Grants. These funds will be used to open, replicate, and expand charter schools across the country and support entities that demonstrate innovative methods of helping charter schools address the cost of acquiring, constructing, and renovating facilities by enhancing the availability of loans and bond financing.
