Increasing virtual memory and advantages

Virtual memory is a technique used on computers by operating systems to utilize more main memory than it is physically available. For example, a system can run 2.3 GB of process on the computer with a physical RAM of 2GB. This technique is implemented by the use of an internal hard disk. The operating system swaps out an inactive process from the RAM to the hard disk and swaps in the required process.

Users of the Windows operating system can increase or customize the size of pages that can be allocated for virtual memory on the system setting. Click on advanced system setting > performance setting > changes to customize virtual memory.


Difference between PATA and SATA hard disk

SATA and PATA are standard types of interfaces used to connect storage devices to computers. Parallel Advanced Technology Attachment (PATA) is sometimes called Integrated Drive Electronics (IDE). It is an old attachment technology that used to have a 40 or 80-wire cable. It transmits data in parallel, which means data move in all the wire simultaneously. 

Serial ATA (SATA) replaced PATA and it transmits data serially which means data move one bit at a time. They are the most common connection found in modern computers.

The PATA hard disk connection is old and was used to transmit data in parallel while the SATA is the latest technology. In SATA data is transmitted one bit at a time. SATA is faster smaller and more flexible to work with.

5 advantages and disadvantages of E learning

Electronic learning (E-learning) also known as online learning is the use of electronic and information communication technology like computers, smartphones, the internet, TV, and other devices to facilitate teaching and learning. E-learning has evolved and has enabled to change of learning from 4-wall classroom learning to an open-time, everywhere kind of learning. It has eliminated the barriers of physical classrooms where both the teacher and student must be present for learning to happen.

E-learning’s main advantage is making learning to be flexible and affordable. It has also eliminated physical classroom barriers. However, it comes with its challenges such as the copyright of digital materials used for learning. It again creates a gap between those who have technologies to enable online learning and those who cannot afford it.


Dot matrix printer advantages and disadvantages

A dot matrix printer is an old printing technology that adopts its name from how it prints characters onto paper. It is made up of a matrix of tiny pins that create a character on paper by striking an inked ribbon against the paper. It is categorized under impact printer since the paper makes contact with the printing mechanism to make characters.

The most common industry that uses dot matrix printer today are a financial institution or other that requires to keep a copy of the data produced. 

Multi-core processor CPU

Types, Advantages, and Disadvantages of Multi-core CPU

A CPU core is an individual processing unit within a device processor for the computer that supports multi-core. The CPUs have more than one core which is capable of executing instructions independently of the others. Current types of computer system that are multitasking and multi-user use of many cores improves overall system performance and execution speed.


Difference between 2.4 GHz vs 5ghz frequencies

The 2.4 GHz and 5 GHz are wireless radio frequencies that transmit and receive signals in wireless devices. Most modern routers can support both frequencies and they are set to auto-select the best for each device. For the best WiFi experience, 5GHz is the best for homes and even offices within the same room.

The main difference between the 2.4 GHz and 5 GHz frequencies is the range they cover, number of devices using the frequency, and the data transmission speeds.

Pointing devices, mouse, trackball, stylus pointing stick

Pointing devices types, functions, and advantages

A computer-pointing device is an input device that is used to move the cursor or pointer on the screen. They are mostly used to click, select, drag, point, and other user movements on the computer screen.

The main types of pointing devices are a mouse, trackpad, trackball, touchscreen, lightpen, stylus pen, and pointing stick. They are used mostly in GUI systems for moving the cursor on the screen. Their main advantage is they are user-friendly, versatile, and can be used for dimensional movements.


Types, advantages, and functions of buffers in os

A buffer is a storage location that is used to store data temporarily as it transits from one device or process to the next. While buffering is the process of using buffers to increase the performance and efficiency of the system using buffers. In an operating system, buffers are used during input and output operations.

The 3 types of buffers in the operating system are single, double, and circular. They are used as temporary storage locations within the system. Their main advantage is to smoothen I/O device operations.
