PDF Full Form

The full form of PDF is “Portable Document Format”. PDF was developed in the 1990s for viewing documents as an electronic image. It was developed and controlled by Adobe Systems. It stores text and images that be opened on any OS. Portable Document Format (PDF) files are especially useful for documents such as magazine articles, product brochures, or flyers in which you want to preserve the original graphic appearance online.

To read PDF file, we need PDF reader software. Adobe Reader is one such software. But it is very large and takes a long time to start up and runs slow (especially on older PC). One of the most popular, lightweight, small size and free software to read PDF files is – Foxit Reader. It runs very fast, starts up quickly.

• Provides perfect mobility and portability: PDF provides mobility and portability. You can read a PDF file anywhere using free tools like Adobe Acrobat Reader.
• Retains the original format: PDF shows the same format, layout, and content regardless of the device, software, and operating system it’s viewed on.
• Highly Secure: PDF provides an easy and secure approach to data transmission and sharing via email.
• Compact – PDFs can be compressed into a small file size that you can easily share with others while keeping full control over the document.
• File Compression: You can compress your raw data file without any loss in quality. It can make data sharing faster.

CPU: Central Processing Unit

The full form of CPU is “Central Processing Unit“. CPU is also called as processor, central processor, main processor or microprocessor. CPU is also known as the brain of the computer. The central processing unit (CPU), is the unit that performs most of the processing inside a computer. To control the flow of instructions and data to and from other parts of the computer, the CPU relies heavily on a chipset, which is a group of microchips located on the motherboard.

Traditionally the term CPU refers to a processor consisting of a control unit and an arithmetic logic unit.

Central Processing Unit (CPU) = Arithmetical Logical Unit (ALU) + Control Unit (CU)

Components of CPU

The CPU is broadly divided into three main parts.

It is a significant part of the CPU. It is responsible for the supervision of all numerical and logical functions, such as subtraction, addition, division, multiplication etc.

CU is the main component of the CPU. It directs a task to the whole system, and it regulates all the computer activities that occur.

A register is a particular type of device for memory. The memory stores the information which the processor has to process or already processed.

PC: Personal Computer

The full form of PC is “Personal Computer“. It is a computer system that is used exclusively by individuals or small groups. Microprocessors are mainly helpful in making these computers; That is why it is also called as microcomputer. Personal computers are manufactured keeping in mind the specific area and task. For example – home computers and computers used in the office. In the market, small scale companies prefer personal computers for their office work. A Personal Computer (PC) can be a microcomputer, a desktop computer, a laptop computer, a tablet PC or a handheld PC.

A typical personal computer assemblage consists of a central processing unit (CPU), which contains the computer’s arithmetic, logic, and control circuitry on an integrated circuit; two types of computer memory, main memory, such as Random-Access Memory (RAM), and auxiliary memory, such as magnetic hard disk or Solid-state drive (SSD) and special optical compact discs, or read-only memory (ROM) discs (CD-ROMs and DVD-ROMs); a Power Supply Unit (PSU), a fan for cooling and various input/output devices, such as a display screen, keyboard and mouse, modem, and printer.

PCs are used in the company to perform tasks such as accounting, desktop publishing and word processing as well as running databases and spreadsheets. At home, PCs are primarily used for multimedia entertainment, such as playing games, accessing the Internet, etc. Even though PCs are intended to be used as single user systems, it is common to link them together to form a network, such as a Local Area Network (LAN).

The full form of UPS is “Uninterruptible Power Supply“. It is used to protect critical loads from utility-supplied power problems, including spikes, brownouts, fluctuations and power outages, all using a dedicated battery. UPS runs on a battery that is used to supply power in the absence of a primary source or when the supply is cut off. Battery size is an important factor in the selection of a UPS system. UPSs are commonly used to protect hardware such as computers, data centers, telecommunications equipment or other electrical equipment where an unexpected power interrupt can result in data loss.

What is the use of UPS in Computer?

An uninterruptible power supply (UPS) allows a computer/PC to keep running for at least a short time when the primary power source is lost. Having your computer connected to a UPS protects it from electrical surges and outages. When computers shut down improperly, such as when a power outage happens, it can damage the computer’s internal parts and cause lost data. Having a UPS helps prevent the computer from being improperly shut down and helps protect the computer and its data. A UPS can run a computer for a few minutes which should give you enough time to save all your data so that you don’t lose it. Many UPS now offer software that automatically saves your data and Shuts down your computer. A UPS isn’t much use if you are working from a laptop as they have their own battery source.

The full form of USB is “Universal Serial Bus“. USB is an industry-standard used for connection, data transfer and power supply between computers, laptops and electronic devices. It is used to define the connectors, cables, and communication protocols used in the bus. The main idea behind its creation was to support file transfer and transmit electric power between devices. Keyboards, mouse, printer, media players, disc drives, power banks are some of the devices that use the Universal Serial Bus (USB). It device can be used across multiple platforms such as Windows, Mac, Android and Linux.

Types of USB

• USB Type-A:- This is the most commonly found one. Used primarily for smartphones, computers, keyboards, mouse, cameras.
• USB Type-B:- These types of usb, have very specific usage and are rare to find. Mainly printers and scanners use it for connecting to an input device.
• Mini USB:- This is an obsolete version of USB. Older models of various gadgets used this type of USB before the next one replaced it.
• Micro USB:- They have a sleek design. They are being used globally for almost all the devices that need a USB connectivity.
• USB Type-C:- More modern in technology, you will find in the new age renewed models of gadgets.

Brief History

• 1994:- USB was developed by a group of seven companies. Compaq, DEC, IBM, Microsoft, Intel, NEC and Nortel. It was developed to make it easier to connect external devices to the PC.
• 1996:- USB 1.0 was released with the speed of 1.5 Mbit/s (Low Bandwidth or Low Speed) and 12 Mbit/s (Full Speed).
• 1998:- USB 1.1 was released, it was the earliest revision that was widely adopted.
• 2000:- USB 2.0 was released, with the speed of 480 Mbit/s named High Speed or High Bandwidth.
• 2008:- USB 3.0 was released with the speed of 5.0 Gbit/s named SuperSpeed.
• 2013:- USB 3.1 was released with the speed of 10 Gbit/s named SuperSpeed+.
• 2017:- USB 3.2 was released with the speed of 20 Gbit/s over the USB-C connector.
• 2019:- USB 4.0 was released with the speed of 40 Gbit/s.Thunderbolt 3 forms the basis of the USB4 standard.
