A nybble, sometimes spelled “nibble,” is a set of four bits. Since there are eight bits in a byte, a nybble is half of one byte. While it may take the average person several nibbles to equal one bite of a cookie, in the computer world, two nybbles always equal one byte.
A pebibyte is a unit of data storage that equals 2 to the 50th power, or 1,125,899,906,842,624 bytes.
In networking, a packet is a unit of data that is transmitted over a network. It consists of two main parts: a header and a payload.
Stands for “Simple Network Management Protocol.” SNMP is used for exchanging management information between network devices. For example, SNMP may be used to configure a router or simply check its status. There are four types of SNMP commands used to control and monitor managed devices: 1) read, 2) write, 3) trap, and 4) traversal operations.
A petabyte is 2 to the 50th power, or 1,125,899,906,842,624 bytes.
Each spoken language has a general set of rules for how words and sentences should be structured. These rules are collectively known as the language syntax. In computer programming languages, syntax serves the same purpose, defining how declarations, functions, commands, and other statements should be arranged.
Stands for “Secure Sockets Layer.” SSL is a secure protocol developed for sending information securely over the Internet. Many websites use SSL for secure areas of their sites, such as user account pages and online checkout. Usually, when you are asked to “log in” on a website, the resulting page is secured by SSL.
A tebibyte is a unit of data storage that equals 2 to the 40th power, or 1,099,511,627,776 bytes. While a terabyte can be estimated as 10^12 or 1,000,000,000,000 bytes, a tebibyte is exactly 1,099,511,627,776 bytes. This is to avoid the ambiguity associated with the size of terabytes. A tebibyte is 1,024 gibibytes and precedes the pebibyte unit of… Read More »
When computers communicate over the Internet, there are often many connections made along the way. This is because the Internet is made up of a network of networks, and two different computers may be on two separate networks in different parts of the world. Therefore, if a computer is to communicate with another system on the Internet, it… Read More »
A terabyte is 2 to the 40th power, or 1,099,511,627,776 bytes. It can be estimated as 10 to the 12th power, or 1,000,000,000,000 bytes. A terabyte is 1,024 gigabytes and precedes the petabyte unit of measurement. While today’s consumer hard drives are typically measured in gigabytes, Web servers and file servers may have several terabytes of space. A… Read More »
