Answer :
Let's go through each term one by one:
Computer Science: Computer Science is the study of computers and computational systems. It involves the theory, development, and application of software and systems to solve problems. Computer Science encompasses a variety of topics including algorithms, data structures, artificial intelligence, programming, and hardware.
Computer Skill: Computer skills are abilities and knowledge that enable someone to use computers effectively. This can include anything from basic tasks like typing, using a mouse, and navigating software, to more advanced skills like programming or system administration.
Hard Disk: A hard disk (also called a hard drive or HDD) is a data storage device used in computers to store and retrieve digital information using one or more rigid rotating disks coated with magnetic material. It is a non-volatile storage medium, which means it retains stored data even when the power is turned off.
Resolution: Resolution refers to the number of distinct pixels that can be displayed on a screen or captured by a camera, typically expressed as width × height (e.g., 1920×1080). Higher resolutions mean more pixels and generally result in sharper, clearer images.
CPU (Central Processing Unit): The CPU, or Central Processing Unit, is the primary component of a computer that performs most of the processing inside a computer. It executes instructions from a computer's hardware and software, performing the basic arithmetical, logical, and input/output operations of the system.
Information Technology (IT): Information Technology refers to the use of computers, networking, storage, and other physical devices, infrastructure, and processes to create, process, store, secure, and exchange all forms of electronic data. IT is typically used within the context of business operations.
Computer Hardware: Computer hardware is the collection of physical elements that constitutes a computer system. This includes the computer case, monitor, keyboard, and mouse; and all the parts inside the computer like the hard disk drive, motherboard, video card, and other components.
