What is a byte?
8 bits. A single character.
What is kilobyte?
1000 bytes. Can be written as 10^3 bytes. KB
What is a megabyte?
1,000,000. Can be written as 10^6 bytes. MB
What is a gigabyte
1,000,000,000. 10^9. GB

1,000,000,000,000,000 10^15 PB
what are character sets
Character sets are collections of characters that a computer recognizes, along with their binary codes
what is ascii
ASCII (American Standard Code for Information Interchange) is a character encoding standard used for representing text and control characters in computers and other devices. It was developed in the early 1960s and has been a foundational element in computing ever since
what is Unicode
Unicode is a universal character encoding standard designed to represent text and symbols from all writing systems around the world. Unicode is the most fundamental and universal character encoding standard. For every character, there is a unique 4 to 6-digit unique hexadecimal number known as a Unicode point. Unicode is standardized among all computing platforms, enabling consistent representation and manipulation of text across different systems and applications.
what is denary
Denary, also known as the decimal numeral system, is the standard system for denoting integer and non-integer numbers. It uses the digits from 0 to 9, and each position represents a power of 10
what is base ten
Base 10 is a method of assigning a place value to numbers. It’s also known as the place value number system, or decimal system, as the numerical value of a number relies on where the decimal point sits.
what is binary
relating to, using, or denoting a system of numerical notation that has 2 rather than 10 as a base.
what is an overflow error
An overflow error occurs when a program attempts to store data beyond the limits of its allocated memory. This can happen in various contexts, such as stack overflow, data type overflow, or buffer overflow.
what is binary shift
Binary shift refers to the process of moving each digit in a string of binary to the left or the right by a certain position
what is a most significant bit
Definition The Most Significant Bit (MSB) is the binary digit in a binary number system that carries the highest weight or value. …
what is a least significant bit
Sometimes abbreviated as LSB, the Least Significant Bit is the lowest bit in binary numbers. It is either the leftmost or rightmost bit in a binary number, depending on the computer’s architecture. If the LSB is on the right, the architecture is called “little-endian.”
what is hexadecimal
Hexadecimal Number System is a base-16 numeral system used in diverse fields, especially in computing and digital electronics. It consists of 16 symbols, including numbers 0 to 9 and letters A to F, offering a compact way to represent binary-coded values. The hexadecimal number system is sometimes also represented as, ‘hex’.
what is base 16
Hexadecimal (also known as base-16 or simply hex) is a positional numeral system that represents numbers using a radix (base) of sixteen. Unlike the decimal system representing numbers using ten symbols, hexadecimal uses sixteen distinct symbols, most often the symbols “0”–”9” to represent values 0 to 9 and “A”–”F” to represent values from ten to fifteen.
what is a nibble
a nibble is 4 bits and half a byte
what is LAN
A local area network (LAN) is a collection of devices connected together in one physical location, such as a building, office, or home. A LAN can be small or large, ranging from a home network with one user to an enterprise network with thousands of users and devices in an office or school.
what is WAN
A wide area network (WAN) is a large computer network that connects groups of computers over large distances. WANs are often used by large businesses to connect their office networks; each office typically has its own local area network, or LAN, and these LANs connect via a WAN. These long connections may be formed in several different ways, including leased lines, VPNs, or IP tunnels (see below).
what is bandwidth
Bandwidth refers to the maximum capacity of a wired or wireless communications link to deliver data via a network connection in a given amount of time. It is typically measured in bits per second (bps), kilobits per second (Kbps), megabits per second (Mbps), or gigabits per second (Gbps)
2
. Bandwidth is often confused with network speed, but it actually represents the volume of data that can be transmitted over a connection in a specific period
what is a client-server network
A client-server network is a distributed application structure that divides tasks or workloads between service providers, known as servers, and service requesters, known as clients. This model is fundamental to many network applications, including email, web browsing, and network printing
