Computer hardware and software
Computer software refers to a collection of procedures, computer programs and codes that perform different functions on a computer system. Software systems are often classified into system software, programming software, and application software. Any physical device used in or with a computer is referred to as computer hardware. A computer display monitor, a CD-ROM and a printer are all examples of hardware.
Functions of computer hardware
The following are the functions of different computer hardware:
Internal system unit components
A processer, also known as the central processing unit (CPU), enables the operating system and operating software run on a system, by executing a set of instructions (Clements, 2006). A motherboard holds the processor and links internal components, such as the random access memory (RAM), together using communication buses. Basic input/output system (BIOS) is responsible for linking computer software and hardware (Clements, 2006). It ensures hardware components perform their functions and turns off processes in the correct way. A power supply unit (PSU) is used to power the components in a computer system while the universal serial bus (USB) and serial enable it to communicate with external devices.
Internal memory components
Internal memory components include the RAM, ROM and cache. Data is written and...

Similar to the suggestions offered by Gahala (2001), Brody (1995) identified several traits to be considered when developing a comprehensive professional development program. Among those traits include the reputation of the trainer, the rewards available to the participants, both tangible and intangible, and the support of the administration. Traditional staff development models have required everyone to participate at the same time and in the same location creating problems such
