What is Bandwidth Baud Bit Bitrate Clob Byte
Bandwidth: Computers are connected through cables all over the world, which also connects one to their ISP (Internet Service Provider). An ISP has super high internet speed and doles out small chunks of this internet for those using it in their homes. The speed of this internet connection on your preferred device all depends on bandwidth.
The bandwidth hinges on wires that connect to the modem, which then connects to the ISP. Depending on the thickness of the wires, your internet speed will be slow or fast.
Example 1: Dial-up: connected by a telephone line to ISP, the bandwidth is usually 50kbps (or 50,000 bits/second). This is slow.
Example 2: Broadband: Usually between 128kbps and 2,000kbps or even more. This is fast.
Baud: The term baud is up for much debate. Baud was used to describe the number of signalling elements (information) that occurred each second in a telecommunication sense. The term was replaced by the more accurate and relevant ‘bits per second’ (or bps) to describe the measurement of the speed of signalling or data transfer. However, as previously stated, this term is up for much debate as people question whether it still has any purpose in the telecommunication world.
Bit: A bit, or binary digit, is the smallest unit of information. It represents one single basic unit of information in connection with computers. Like all electrical machinery, a computer has two states: “on” (1) and “off” (0). A bit is both a 1 and a 0.
Example: coding for words in computers is only written in a series of 1 and 0. The letter “A” is stored on a computer as 01000001.
Bitrate: The bit rate (sometimes written as bitrate) is the number of bits per second that can be transmitted along a digital network or conveyed per unit of time.
Blob: Blob (pronounced BLAHB), or binary large object, is a storage space for binary data (see bit). Due to the fact that it can store larger objects, image and sound files are generally stored, uploaded or downloaded via this.
Bps: Bps, or bits per second (bit/sec), is common measurement for the speed of data travel for computer modems and transmission carriers. (See bit and baud).
Byte: In short, a byte is larger than a bit (and, in fact, made of bits). There are 1024 bytes in 1 KB (kilobyte): 10010101 = exactly 1 byte. In early computing days, only 8 bits could be send and received at a time, so it made sense to join these 8 lines together with other 8 lines (of bits) to make a byte.
Example: In a small gif image of about 4000KB, there are roughly 4000 lines of 8 bits (1’s and 0’s). So, 8 x 4000 = 32,000 1’s and 0’s for a single small gif image.
CLOB: CLOB (character binary object) is just like BLOB, only it is used to store large formatted and unformatted texts: such as JSON’s and XML docs.
Data: Every single piece of software is divided into two categories: 1. Data; and 2. Programs. Programs are actually collections of instructions for manipulating data and data refers to bits or bytes stored in electronic memory. The correct way to describe multiple data is datum but the word data has taken over as both the singular and plural meaning.
Data Transfer Rate: In short, the term ‘data transfer rate’, refers to the amount of digital data moved from one place to another. Typically measured in bps (bits per second), this is often confused for bytes per second because there are 8 bits (b) to a byte (B) and, when abbreviated, they appear similar.
Example: a data transfer rate of 80Mbps is only transferring 10MB per second. ISP companies use the term Mbps to make it look like their customers get more for their money.
