Computer Science -Optical Drives
Optical drives utilize lasers to inscribe data onto a detachable disc that may be stored independently from the computer system. These optical discs, exemplified in Figure 7.5, exist in numerous formats: Compact discs (CDs) were the initial optical storage medium, capable of storing up to 680 MB of data on a single disk. Digital video discs (DVDs) enhance storage density, permitting the accommodation of up to 17 GB of data on a single disk. Blu-ray discs (BDs) provide the greatest capacity among optical formats, enabling the storing of up to 128 GB of data on a single disk.
Various categories exist for each type of optical media. Read-only CDs are manufactured with pre-recorded data that cannot be altered by users. Recordable discs enable users to inscribe data into them; however, this material is permanently retained and cannot be wiped or altered. Rewritable disks are erasable and can be reused following data recording. Optical drives rapidly rotate discs while employing a laser to read and write data. Consequently, optical drives, like to HDDs, exemplify spinning disk media.

Computer Science – Enterprise Storage Services
Enterprise Storage Services Organizations typically do not wish to manage significant amounts of removable media or store data on drives connected to individual PCs. Instead, they prefer centralized business storage services, which store data in a single area and allow multiple users to access it.
Cloud Storage
Today, cloud storage services enable businesses to outsource storage, employing services offered by a vendor who controls storage resources and makes them available to users wherever they are located.
File Servers
Businesses that do not use cloud services may run their own centralized storage services to satisfy the needs of their employees. They frequently accomplish this by operating a file server, which is essentially a computer with a lot of storage loaded. The file server is located on the network, and users can access it from their own PCs. Network attached storage (NAS) systems are self-contained file servers that connect directly to a network and give users access to shared storage space.

Computer Science – Keyboard and Mice
Peripheral devices like keyboards and mouse let you input data into a computer system. You can enter text and numbers with the keyboard, and you can move items and operate in a graphical user interface (GUI) with the mouse. For desktop computers, keyboards and mouse are essentially essential components. Although external keyboards and mouse are frequently integrated into laptops, many laptop users find that these full-sized devices are more user-friendly than the smaller ones that are included inside laptops.

Computer Science – Display
Displays are essential for a computer to be functional for its users. The standard display is a monitor that enables the user to observe the computer's activities during interaction, as illustrated in Figure 8.2. Servers typically lack linked screens, whereas laptops and desktop computers require displays to be functional for users. Similar to keyboards and mouse, laptops are equipped with integrated displays; nevertheless, users frequently utilize bigger monitors on their workstations while operating their laptops in an office setting. Touchscreen screens are popular as they enable users to interact directly with the screen without the need for a keyboard or mouse. Based on business needs, computers may utilize alternatives to conventional displays for output presentation. For instance, PCs can be connected to smart televisions or projectors to present content to extensive audiences.

Computer Science - Servers
There exists an additional kind of nonportable computers that warrants your attention. Servers are robust computers designed to perform a certain purpose. Companies may utilize servers for internal file sharing, internet hosting, database management, or several other services. It suffices to recognize that servers are robust computers usually located in specialized data centers designed to accommodate numerous servers in dedicated racks.

Computer Science - Laptops
With the main advantage of being incredibly portable, laptop computers are remarkably comparable to the desktop computers that once occupied every office and cubicle. They consolidate all of the computer's parts, such as the keyboard, trackpad, and monitor, into a single unit that is portable. Additionally, laptops have batteries that enable them to function for hours without requiring an electrical connection. The power of a contemporary laptop can rival that of a desktop computer. The one drawback is that laptops are usually more expensive than desktop computers, and most laptop users also want a full-sized monitor on their desk, which raises the whole cost of their workspace.

Computer Science – Tablets
In terms of size and functionality, tablets fall somewhere between smartphones and computers. Although tablets lack a laptop's actual keyboard and computing capability, they do feature larger screens than phones. Tablets are frequently utilized in settings where staff members are on the go and interacting with clients and require a portable device. Touchscreen kiosks, such those in hotel lobby areas, are frequently powered by them as well. Specialized tablets called e-readers were created especially for reading books and other digital materials. They frequently exhibit text in an easily readable format using electronic ink (e-ink) technology.
Convertible laptops,may be flipped around and used as either touchscreen tablets or normal laptops.

Computer Science - Wearable devices
As computing technology develops further, it is making its way into increasingly more compact and individualized gadgets. At the front of this trend are wearable technology, such as the smartwatch. An unprecedented degree of integration into our daily lives is made possible by these small but mighty devices, which bring computing capabilities to the body itself. Among wearable technologies, smartwatches are arguably the most well-known. In addition to being watches, they also function as fitness trackers, notification hubs, and even smartphone extensions. Because the wristwatch has its own operating system, it can run a number of apps without a phone. Although interactivity may be limited by the small screen size, designers have addressed this issue by including contextual awareness, touch gestures, and voice control into the user interface.
In addition to smartwatches, other wearable technology includes health monitors, fitness bands, and smart eyewear. Each is made with regular wear and portability in mind, frequently emphasizing specialized features that enhance the capabilities of larger devices. In order to sync data or take advantage of greater processing power and storage when needed, they frequently connect to other computer devices, such as laptops or smartphones.
