2. You organize files by storing them in
- archives
- folders
- indexes
- lists
There are several ways to organize files, but one of the most common ways is by storing them in folders or directories.
Folders are used to group related files together, making it easier to locate and manage them. For example, you might create a folder called "Work" and store all your work-related files in that folder. You could further organize the "Work" folder by creating subfolders for different projects or clients.
In addition to folders, you can also use file naming conventions to help organize files. For example, you might use a consistent naming convention for files, such as starting each file with the date followed by a brief description of the contents. This can make it easier to sort and locate files based on their names.
Other ways to organize files include using tags or labels to categorize files, creating shortcuts or aliases to frequently accessed files, and using file management software that allows you to create custom categories or tags.
- Printers
- Speakers
- Floppy disk drives
- Keyboards
A common shared resource in a computer network is a printer. Printers are often shared resources because they can be expensive to purchase and maintain, and many users in a network may need to print documents. By sharing a printer, multiple users can access it and print documents without having to purchase their own printer.
Other common shared resources in a computer network include file servers, which allow multiple users to store and access files from a central location, and Internet connections, which are often shared among multiple users in an office or household.
In general, any resource that is expensive to purchase or maintain, or that multiple users need to access, is a good candidate for sharing in a computer network. The key is to ensure that the shared resource is set up properly and managed effectively to avoid conflicts or performance issues.
4. Which device is required for the Internet connection?
- Joystick
- Modem
- CD Drive
- NIC Card
To connect to the Internet, you need a device that can access the Internet and communicate with other devices on the network. The most common device used for this purpose is a modem or a router.
A modem is a device that connects your computer or other devices to the Internet through your Internet Service Provider (ISP). It converts the signals from your ISP into a format that your devices can understand and vice versa.
A router, on the other hand, is a device that allows multiple devices to connect to the Internet at the same time. It also provides network security features such as firewalls, and it can help prioritize network traffic to optimize performance.
Many modern devices, such as smartphones and laptops, have built-in wireless capabilities that allow them to connect to a Wi-Fi network. In this case, a wireless router is required to provide the Wi-Fi signal for these devices to connect to.
In summary, to connect to the Internet, you need a device that can access the Internet and communicate with other devices on the network, such as a modem or a router.
5. What is a light pen?
- A Mechanical Input device
- Optical input device
- Electronic input device
- Optical output device
A light pen is a type of input device that allows the user to interact with a computer by pointing a pen-shaped device at the computer screen. The light pen was popularized in the 1960s and 1970s as a means of interacting with early computer systems.
6. UNIVAC is
- Universal Automatic Computer
- Universal Array Computer
- Unique Automatic Computer
- Unvalued Automatic Computer
- UNIVAC (Universal Automatic Computer) was the name of the first commercially available electronic digital computer. It was designed and built by J. Presper Eckert and John Mauchly, and was delivered to the United States Census Bureau in 1951.
- The UNIVAC was a large, room-sized computer that used vacuum tubes to perform calculations. It had a memory capacity of 1,000 words and could perform about 1,000 calculations per second. The UNIVAC was the first computer to be used for business applications, such as payroll and accounting, as well as for scientific calculations.
- The success of the UNIVAC marked the beginning of the computer age and led to the development of more advanced and powerful computing technologies. It also had a significant impact on society and the economy, paving the way for new industries and changing the way people work and live.
7. CD-ROM stands for
- Compactable Read Only Memory
- Compact Data Read Only Memory
- Compactable Disk Read Only Memory
- Compact Disk Read Only Memory
- CD-ROM stands for Compact Disc Read-Only Memory. It is a type of optical disc that can store large amounts of data, including text, images, audio, and video. CD-ROMs were introduced in the 1980s and quickly became a popular means of distributing software, games, and multimedia content.
- A CD-ROM consists of a flat, circular disc made of polycarbonate plastic, with a diameter of 120mm and a thickness of 1.2mm. The disc is coated with a layer of aluminum, which is used to reflect laser light. The data is stored on the disc in the form of pits and lands, which are read by a laser beam.
- CD-ROMs are read-only, which means that data can be read from them, but not written to them. To write data to a disc, a different type of optical disc, such as a CD-R or CD-RW, is required.
- CD-ROMs have largely been superseded by newer technologies, such as USB flash drives and online distribution platforms. However, they remain a useful means of distributing large amounts of data, particularly for archival and historical purposes
8. ALU is
- Arithmetic Logic Unit
- Array Logic Unit
- Application Logic Unit
- None of above
- ALU stands for Arithmetic Logic Unit. It is a digital circuit that performs arithmetic and logic operations on input data. The ALU is a fundamental component of most central processing units (CPUs) and is responsible for carrying out the mathematical and logical operations required by computer programs.
- The arithmetic operations performed by an ALU include addition, subtraction, multiplication, and division. The logic operations performed by an ALU include logical AND, OR, and NOT operations, as well as comparison operations, such as equal to, less than, and greater than.
- The ALU operates on binary data, which means that it works with numbers represented in base 2, using only 0s and 1s. The input data is typically stored in registers within the CPU, and the ALU retrieves the data from these registers, performs the required operations, and stores the result back in a register.
9. VGA is
- Video Graphics Array
- Visual Graphics Array
- Volatile Graphics Array
- Video Graphics Adapter
- Video Graphics Adapter And Video Graphics Array
- VGA stands for Video Graphics Array. It is a display standard used for video output in computers and other devices. VGA was introduced by IBM in 1987 and quickly became a popular standard for displaying graphics on computer monitors.
- VGA defines a display resolution of 640x480 pixels, with 16 colors or shades of gray. The standard uses analog signaling to transmit video signals from the computer to the monitor. VGA connectors typically use a 15-pin D-sub connector, which is still commonly used on computer monitors and projectors today.
- Video Graphics Adapter (VGA) is an older video display standard that was introduced by IBM in 1981. It was the first widely used video display standard for IBM-compatible personal computers and remained a popular standard until it was superseded by the Video Graphics Array (VGA) standard in 1987.
