Answers & Comments
Answer:
1) Portable Devices:
Smartphone
Laptop
Flas Drive
External Hard Disk
Calculator
2) The term random access as applied to RAM comes from the fact that any storage location, also known as any memory address, can be accessed directly.
3) A computer memory are storage devices which stores information.
4) A Hard Disk is a device which is used to store data permanently until the data is removed.
5) A CD is a compact disc which is used to store and share data as it is portable.
6) Primary Memory is the easiest to access
7) DVD, in full digital video disc or digital versatile disc, type of optical disc used for data storage and as a platform for multimedia.
8) These are binary digits, or bits for short. Single bits are too small to be much use, so they are grouped together into units of 8 bits. Each 8-bit unit is called a byte. A byte is the basic unit which is passed around the computer, often in groups.
9) A microprocessor is a computer processor where the data processing logic and control is included on a single integrated circuit, or a small number of integrated circuits. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer's central processing unit.
10) A motherboard is the main printed circuit board in general-purpose computers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit and memory, and provides connectors for other peripherals.
