  STORAGE💣 Storage is a process through which digital data is saved within a data storage device by means of computing technology.  Storage is a mechanism that enables a  computer to retain data, either temporarily or  permanently. Storage is among the key components of a computer system and can be classified into several forms, although there are two major types: Volatile Storage (Memory):  Requires a continuous supply of electricity to store/retain data. It acts as a computer’s primary storage for temporarily storing data and handling application workloads. Examples of non-volatile storage include cache memory and random access memory (RAM). Non-Volatile Storage:  A type of storage mechanism that retains digital data even if it’s powered off or isn’t supplied with electrical power. This is often referred to as a secondary storage mechanism, and is used for permanent data storage requiring I/O operations. Examples of volatile storage include a hard ...

  CENTRAL PROCESSING UNIT(CPU)💻 The CPU is the brain of the computer that processes and executes digital instructions from various programs; its  clock speed  determines the computer's performance and efficiency in processing data. The CPU is an  electronic  machine that works on a list of computer things to do, called  instructions . It reads the list of instructions and runs ( executes ) each one in order. A list of instructions that a CPU can run is a  computer program . He  clock rate , or speed of a CPU's internal parts, is measured in  hertz  (Hz). Modern processors often run so fast that gigahertz (GHz) is used instead. One GHz is  1,000,000,000  cycles per second.

 ICT IN DAILY LI FE📹 💫ICT systems are often confused with computers; however, they are not the same thing.  Computers refer to the hardware that forms part of an ICT system . The ICT system refers to the overall set-up, consisting of hardware, software, data and the people that use it. ICT systems are often confused with computers; however, they are not the same thing. Computers refer to the hardware that forms part of an ICT system. The ICT system refers to the overall set-up, consisting of hardware,  software , data and the people that use it. It commonly includes communication technology, such as the internet. Information and communication technology (ICT) is a field that is related to computers and communication networks. It can also be in the form of audiovisuals, for example, film and digital productions. Digital technologies use data, such as text, numbers, images, sounds and videos. Computers use this data to show information. Hardware refers to  the comput...
