Study Notes

Computer Architecture and Memory

CISC stands for Complex Instruction Set Computers.
Fastest memory type is Cache memory, which is quicker than main memory or hard disks.
A processor with an 8-bit address bus can identify 256 memory locations (2^8).
RISC (Reduced Instruction Set Computer) architecture does not include Pentium IV.

Operating Systems

Operating Systems (OS) are system software that manage computer hardware and software resources.
File Management encompasses files, folders, and directory systems.
OS provides interactive capabilities, including Graphics User Interface (GUI) and data distribution.
Single task operating system example is MS-DOS.
Linux uses the ext2 file management system.

Software Types

Application software is designed for end-users (e.g., MS Word, VLC Player).
System software, like operating systems, serves as an interface between users and computers.
A compiler is part of application software.

Windows Operating System

Windows NT is a version designed like a server for network operations.
The default folder for saving files in Windows applications is "Documents."
Shift + Delete command permanently deletes files in Windows 7 and MS-DOS.
Windows XP was introduced in 2001.

Computer Generations and Basic Concepts

First-generation computers utilized vacuum tubes.
Volatile memory is exemplified by RAM; non-volatile includes ROM.
Output devices include monitors and printers; input devices include keyboards and mice.
1 Kilobyte equals 1024 bytes.

Boolean Algebra

Boolean algebra operates on one or more signals through basic electronic circuits known as gates.
The NOT gate serves as a logical inverter, reflecting the essence of Boolean logic.
True is represented by the value 1 and False by 0 in logical constants.

Programming Basics

High-level language programs are referred to as source code and can also be compiled into object or executable code.
Arrays in C++ are derived data types, and the syntax defining them can reference their size.
Characters in arrays are stored as strings and can be initialized with various formats.

Data Structures

Examples of structures in C++ include defining data types like integers and characters.
Memory allocation for data types varies, such as 4 bytes for integers or typically 1 byte for characters.
C++ syntax for character arrays can utilize both array and single-character initialization forms.
