FLV vs. MP4 – Why MP4 is Better?

MPEG-4, also known as MP4 is a graphics and video file type developed by the Motion Pictures Expert Group who are considered industry leaders when it comes to digital and video file formats. The main feature of this file format is that it enables users to save subtitles and images besides storing the contents. This file is better suited to low bandwidth media like smartphones and broadband internet connections.

FLV vs. MP4

FLV files are used for online video streaming and are popular streaming sites such as YouTube, Netflix, and Vevo among others. This is attributed to the fact that FLVs stream progressively whereas MP4 must be downloaded in their entirety to play. These file formats also have their similarities considering that they contain similar video and audio codecs. The only difference lies in their storage (container). If you want to play an FLV file format in a smartphone or share it with friends, the better way to complete this task is to convert it to MP4.

Why MP4 file formats

Better graphics

One of the main features of the MP4 file format is its ability to support various bits of data. As a result, this feature allows for the mixing of various visual elements like text, animation layers, and graphics. MP4 also support things like stage descriptions and embedded interactivity features. This makes this file format resourceful when creating files used for multimedia presentations.

Low bandwidth

MP4 files are made for narrow bandwidths. Ideally, bandwidth refers to the amount of data transmitted by a device within a set amount of time. Bandwidth is expressed in bits per second. That said, the ability to use narrow bandwidths means that MP4 files are easily transferable across different devices using wireless technologies.

Compatible with most devices

Compatibility is not much of a concern when using MP4 files as opposed to FLV. Ideally, FLV is a proprietary format that is not supported by some key mobile devices. Also, consortiums that make electronic devices support MPEG -4 video files. Companies like Apple, Sony, Samsung, and JVC among others have media devices that actively use MP4 files.

MP4 files have their unique pros and cons. Compatibility with multiple devices is one of the main strengths of this file format. Their main limitation is that you can only play archived content and is not the best file format for live streaming. This explains why FLVs are used in video streaming sites and MP4s by most mobile devices.…

Functions of a computer memory

The primary role of computer memory is to store all data on the computer. Depending on the type of data, the memory performs other functions as well. Whereas some people may not be interested in computers or IT, it is essential to understand some of the vital functions of computer memory.Nowadays, most employers need individuals who are tech savvy.  Below are some of the functions.

Primary functions of a computer memory

RAM

RAM is the acronym for random access memory. It is used to provide storage for temporary data. This means that whenever the computer needs some data, instead of going to the computer’s hard drive to collect the data, it will get the information from its RAM. This is because the RAM stores the applications that are frequently used. This makes it easier for the computer to access the information. When the machine is switched off, the data is moved to the hard drive to create room for new data.

Hard drive

This is the core of a computer’s storage of data. It stores all data in the computer from the operating system, documents, and images. The hard drive is the disk that has a magnetic coating. It operates efficiently by having one arm that moves as it reads and copies all data from the rotating disk. This allows individuals to save and open new data from the hard drive.

ROM

This is the acronym for read-only memory. Data that is saved here is used to control the basic functions of the computer like starting up the computer, detecting peripherals and turning on the computer fan among others. The system or individuals cannot edit this data. Even after switching off the computer, the information is not moved to any other storage. Therefore, ROM is an example of a non-volatile storage which simply means that the data stays in place even when the system is off.

Flash memory

Flash memory is a term for electronically-erasable-programmable-read-only- memory (EEPROM). It is used for essential programs of the system as well as the video game cards of the computer. Unlike other memories which are used to erase and copy data byte by byte, EEPROM is used to edit data in groups of bytes, therefore, making it easy to use. It is also convenient for other devices like cameras and memory sticks. This is because data stored in these devices change from time to time.…

Cybersecurity tips for retailers and consumers

It is crucial for retailers and consumers to prevent themselves from financial fraud and scams like identity theft. Previously, IT administrators focused mainly on the consumers but retailers are also getting a lot of attention lately. Consumers may lose their payments and confidential data, and the retailers may suffer catastrophic consequences when a cyber-attack hits their systems. This article enlists some of the tips which retailers can use to protect their data and those of their consumers from a cyber-security attack.

Protection tips from cybersecurity attacks

Amplify threat detection capabilities

Most organizations often have preventive security measures, but at times like the holiday season, their systems must have extra protection. Their threat monitoring capabilities should be on top of the game. Additional authentication steps should be present during the shopping peak season to monitor transactions and block out the suspicious transactions. However, they should not be too much because this may thwart some consumers. Therefore, organizations should implement techniques that will monitor suspicious activities and keep them at bay while not affecting the consumers’ user experience.

Implementing incidence response plans

Organizations should ensure that they have a functioning response plan for every threat that is detected. This may include rebuilding the system and having technical control. To add value to the scheme of things, the response plans should be both procedural and communicated to the staff in the organization. In addition to this, there should be a backup plan in the case that the security measures fail to recognize and counter the attacks.

Prioritizing employee awareness

When you add employees to your organization, you should ensure that they are trustworthy people. This is especially for temporary employees who may be out there to get money including causing data breaches. Therefore, it is essential to train them as part of the staff on boarding process to increase their awareness of this subject matter. This is because some of them may cause data breaches accidentally because they do not know how the systems work.

Sharing threat data

Criminals often share attack methodologies across various databases. Therefore, retailers should also threat data to procure an additional layer of safety. They can share the threat data and help each other to formulate the strategies to counter the threat. When they share this information with each other, it becomes easy for the other retailers to recognize the danger and come up with better strategies to deal with it.…
