I am a CTO with over 5 years of experience in start-up and over 10 years in working at managing position for big companies. I am also a full-stacks developer with over 12 years in system design, product development and technology product deployment. User experience and system security are the things I care about most.
Username Definition
A username is a name that identifies a user in a computer system or a website. Usernames are often unique, meaning two users cannot share the same username. Also, usernames are usually paired with a password, and both may be required to sign in to a computer or website. Usernames
Password Definition
A password is a secret set or characters and numbers to something like a computer or website. Passwords are often paired with usernames or email addresses to identify specific users. For good security, your passwords should be long, difficult to guess, but easy for you to remember. Your passwords should
Bit Definition
A bit, which is short for “binary digit”, is the smallest form of data on a computer. Bits can only be 1 or 0. If a bit is 1, then it is “on” or true. And if a bit is off, then it is “off”, or false. The concept of
Byte Definition
A byte is a collection of 8 bits. Bits can only be 1 or 0. If a bit is 1, then it is “on” or true. And if a bit is off, then it is “off”, or false. Because bytes are collections of 8 bits, they range from 00000000 to
Kilobyte Definition
A kilobyte is a collection of about 1,000 bytes. In the metric system, kilo is 1,000, and in some cases a kilobyte is defined as 1,000 bytes. This definition is commonly used by storage medium companies and to measure data transfer speeds. But because computers work in binary, computer scientists
Megabyte Definition
A megabyte is a collection of about 1,000,000 bytes, which is around 1,000 kilobytes. In the metric system, mega is a prefix for 1,000,000, or 106. So in some cases, a megabyte is defined as 1,000,000 bytes. But because computers work in binary, computer scientists usually define a megabyte as
Gigabyte Definition
A gigabyte is a collection of about 1 billion bytes, which is around 1,000 megabytes. In the metric system, giga is a prefix for 1 billion, or 109. So in some cases, a gigabyte is defined as 1 billion, or 1,000,000,000 bytes. Storage media companies usually use this definition of
Terabyte Definition
A terabyte is a collection of about 1 trillion bytes, which is around 1,000 gigabytes. In the metric system, tera is a prefix for 1 trillion, or 1012. So in some cases, a terabyte is defined as 1 billion, or 1,000,000,000,000 bytes. Storage media companies usually use this definition of
