A register is a small, high-speed storage location in the CPU used for temporarily holding data, instructions, or addresses during processing.

OR

A register is a temporary storage area in the processor of a computer where data and instructions are kept for immediate processing.

(3b)
(i) Special purpose register:
(PICK ANY ONE)
- AX register
- BX register
- CX register
- DX register

(ii) General purpose register:
(PICK ANY ONE)
- Program Counter (PC)
- Instruction Register (IR)
- Accumulator (ACC)
- Memory Address Register (MAR)

(3c)
(PICK ANY ONE)
A special purpose register performs a specific function in the CPU during processing, while a general purpose register is used for storing different types of data temporarily during program execution.

OR

Special purpose registers have fixed and dedicated functions, while general purpose registers can perform various operations depending on the instruction given.

OR

Special purpose registers control and coordinate processing activities in the CPU, while general purpose registers mainly hold data and intermediate results during calculations.

(3d)
(PICK ANY TWO)
(i)Register:
They are located inside the CPU and operate at very high speed.

-Main memory:
This is located outside the CPU and operates more slowly.

(ii) Register:
This store small amounts of data temporarily for immediate processing.

-Main memory:
This stores larger amounts of data and programs currently in use.

(iii) Register:
They are more expensive and have very limited storage capacity.

-Main Memory:
This is less expensive and has a larger storage capacity.

(iv) Register:
They are directly accessed by the processor during execution.

-Main Memory: Data must first be transferred to register before processing can take place.

An integrated software package is a collection of related application programs combined into one software system that can perform different tasks and share information easily with one another.

OR

An integrated software package is a software application that combines several programs and functions into a single package, enabling users to carry out different operations while sharing the same data and interface.

(PICK ANY ONE)
EXT mode is used to extend the selection of cells in a spreadsheet. It allows the arrow keys to highlight additional cells for formatting, copying, deleting, or editing.

OVR mode is used to replace existing text with new text while typing in a spreadsheet cell. In this mode, any new character typed automatically overwrites the character already present instead of inserting new characters between the text.

OR

EXT mode in a spreadsheet is used for extending the selection of cells. When it is activated, the user can use the arrow keys to select or highlight a wider range of cells from the current position. It helps in carrying out operations such as copying, formatting, moving, or deleting selected cells.

OVR mode, also known as overtype mode, is used to overwrite existing text in a cell. In this mode, newly typed characters replace the existing characters one after another instead of creating spaces or adding new text. It is mainly used when editing or correcting entries in a spreadsheet document.

(5c)
(i) Insert mode
(ii) Overtype mode
